Description

[0001]
BACKGROUND OF THE INVENTION
The present invention has fluidity in a heated state and is formed into a plate shape and film-wrapped in a state having this fluidity, and the formed state is retained by cooling after film packaging, It is related with the manufacturing method of the plate-shaped foodstuff which can use for food by opening a packaging bag in the state which does not break as much as possible.
[0002]
[Prior art]
Currently, many of the chocolates, caramels, candies, sheepskins, jelly, cheeses, strawberries, seaweeds, and curry roux and stew that are provided in a solid state are fluid when heated. After these mold materials are packed in a mold in the heated state and molded, they are allowed to cool at room temperature, or forcedly cooled using cooling water, cooling air, etc., and solidified. On top of that, it is packed and put in circulation.
[0003]
Alternatively, these foods are formed by rolling these constituent materials having fluidity in a heated state with a roll machine and then leaving them to cool at room temperature, or using cooling water or cooling air. It is forced to cool and solidify, and then packed in a bag for distribution.
[0004]
[Problems to be solved by the invention]
However, in such a food, it is necessary to make a package such as the bagging after the molding with the mold or the like. In addition, excess air easily enters the package in the packaging stage after the molding, and it is easy to cause deterioration in food quality due to the gap between the air and the package over time. For this reason, in this type of food, special consideration is required at the packaging stage such as packaging after molding in a sterile room, and preservatives must be added to the food. It was often done.
[0005]
In addition, it is difficult to finish the food thinly due to the separate packaging after molding by the mold, and in order to evenly adjust the weight and shape of the product, it is exceptional to stuff the constituent materials into the mold It was something that required consideration.
[0006]
Accordingly, an object of the present invention is to make it possible to easily form and package this type of food so as to form a plate having a desired thickness in a state where quality is not deteriorated.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, a method for producing a plate-shaped food packaged with a film includes the following steps (1) to (4).
(1) The first heat seal and the conveyance which are continuously applied in the direction along the conveyance direction of the film while conveying the film having the sealant layer which is heat-sealed so as to be capable of interfacial peeling, delamination or cohesive failure A second heat seal applied in a first order while forming a three-side seal packaging bag or a four-side seal packaging bag in succession by a second heat seal applied at intervals in the direction crossing the direction; A filling step of filling the constituent material of the food that is solidified by heating and fluidity in the heated state between the second heat seal applied in the next order in the heated state;
(2) Until the second heat seal applied in the next order is applied, the filled constituent material is Between a pair of squeezing rollers to spread A degassing step of pressing the film;
(3) A molding step of pressing the packaging bag filled with the constituent material and leveling the constituent material filled into the packaging bag to form a plate shape;
(4) A cooling step of cooling the packaging bag containing the food formed in the plate shape so as to solidify the constituent material of the food and keeping the food in a plate shape
[0008]
Here, foods made of constituent materials that are fluid in the heated state and harden when cooled include chocolate, caramel, candy, sheepskin, jelly, cheese, rice cakes, seaweed, solidified curry roux and stew. Lou is planned.
[0009]
Typically, a chocolate generally contains cocoa paste, cocoa butter, dairy products, and sugar in its constituent materials, and these actions have fluidity in a heated state but harden when cooled.
In addition, for example, caramel and candy generally contain sugar and various sugars in their constituent materials, and they have fluidity in a heated state by these actions, but harden when cooled.
In addition, for example, sheep yolk and jelly generally contain agar, gelatin, and sugar in their constituent materials, and these actions have fluidity in a heated state but harden when cooled.
In addition, for example, in cheese, milk fat and milk protein are contained in its constituent materials, and by these actions, it has fluidity in a heated state but hardens when cooled. In addition, for example, in the case of strawberry or eel wax, starch is contained in the constituent material, and due to this action, it has fluidity in a heated state but hardens when cooled.
In addition, for example, in the case of Carreru and Stuhl, it has fluidity in the heated state due to the action of lipids contained in these constituent materials, but becomes solidified and solidified when cooled.
[0010]
First, in the filling step, the three-side packaging bag or the four-side packaging bag is formed by a film having a sealant layer that is heat-sealed so as to be capable of interfacial peeling, delamination, or cohesive failure. A plate-shaped food product that is formed into a plate shape by a manufacturing method and that is shaped by cooling is pulled in a direction that separates the film portions on both sides that constitute such a packaging bag, so that any of the packaging bags It can be easily taken out from the packaging bag by opening the heat seal from one side.
[0011]
Further, the degassing step allows the air contained in the constituent material filled in the filling step to be contained in the constituent material until the second heat seal applied in the next order is applied. As long as it is removed, it is possible to prevent excess air from remaining in the constituent material enclosed in the packaging bag. In addition, in the film that has been flattened by the first heat seal until the second heat seal applied in the next order is applied, the second applied in the previous order. The material is densely distributed in the space up to the formation position of the second heat seal and the second heat seal applied in the next order, and the second heat seal applied in the next order is applied and formed. It is possible to prevent the air due to the filling gap from remaining in one packaged bag. As a result, it is possible to enclose the constituent material in a state in which excess air is prevented from entering the packaging bag as much as possible, and alteration of the plate-like food molded from the constituent material due to such air Can be prevented as much as possible, and can withstand long-term storage.
[0012]
Further, the constituent material filled in the packaging bag by the molding step is formed into a plate shape following the internal space of the packaging bag, more specifically, the first heat seal applied to the packaging bag. It is possible to form a plate-like food having a plate shape that follows the flat and square inner space formed by the inner edge of the second heat seal and the inner edge of the second heat seal. Moreover, the plate-shaped food which makes the plate shape shape | molded in this way shall be covered with the said film without the clearance gap with the said deaeration process. If the first heat seal and the second heat seal are regularly formed, each plate-shaped food enclosed in each continuously formed packaging bag has a uniform and substantially uniform weight and shape. Plate-like food, and the stable supply of the standardized product is possible. In addition, since the molding is performed in a state where the constituent material is sealed in the packaging bag, the plate-like food to be molded can be thinned without any trouble, and in the cooling step, the plate-like food can be reduced in a short time. Can be properly cooled and solidified.
[0013]
In addition, the cooling process allows the final consumption of the food that is formed in the packaging bag by forming the constituent material into a substantially rectangular plate shape in the molding step while keeping the substantially square plate shape. Can be provided until the person provides food.
[0014]
Cooling methods in such a cooling process include cooling by leaving at room temperature, forced cooling by immersing the packaging bag in a water tank in which cooling water is stored, blowing cooling air to the packaging bag, or placing it in a cooling atmosphere. Forced cooling will be planned.
[0015]
Further, the packaging bag is provided between a pair of cooling plates provided with a cooling water flow path and cooled by the cooling water flowing through the flow path, and at least one of the pair of cooling plates is transferred to the other cooling plate. By using a cooling device that is moved in the direction to be close to the packaging material, the constituent material filled in the packaging bag can be cooled at the same time while being formed into a plate shape in the cooling device. .
[0016]
That is, in this specification, cooling means cooling at a temperature at which the constituent materials are not frozen.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, typical embodiments of the present invention will be described.
[0018]
The manufacturing method according to this embodiment is formed into a substantially rectangular plate shape with fluidity and film-wrapped, and the molded state is retained by cooling, and the packaging bag H is opened to open the packaging bag H. It is for manufacturing the plate-shaped foodstuff M which can be provided to edible with plate shape.
[0019]
That is, the manufacturing method according to this embodiment includes steps 10, 20, 30, and 40, the outline of which is shown in FIGS.
[0020]
The first step is performed continuously in the direction along the transport direction x of the film F while transporting the film F having the sealant layer 2 that is heat-sealed so as to be capable of interfacial debonding, delamination or cohesive failure. While forming a three-side seal packaging bag or a four-side seal packaging bag successively in succession by one heat seal 8 and a second heat seal 9 provided at intervals in the direction crossing the conveyance direction x, It is the filling process 10 in which the constituent material Ma of the plate-like food M is filled between the second heat seal 9 applied in step 2 and the second heat seal 9 applied in the next order.
[0021]
The constituent material Ma of the plate-like food M to be filled in the filling step 10 is a constituent material of food that has fluidity in a heated state and solidifies when cooled, typically chocolate, caramel, candy, cane, jelly Constituent materials such as curry roux and stew to be provided in the solid state are planned.
[0022]
The three-side sealed packaging bag is a packaging bag formed by three-side sealed packaging. Such a three-side seal packaging is a direction along the transport direction x of the film F while transporting the film F in a state where the length direction of the film F is aligned with the transport direction x in a state where the long film F is folded in half. The first heat seal 8 is applied continuously, and the second heat seal 9 is applied at intervals in the direction crossing the conveyance direction x, so that the seal portion 3 is provided on at least three sides other than the folding side y. The packaging bags H that are formed and enclose the constituent material Ma are successively formed.
[0023]
The four-side sealed packaging bag H is a packaging bag formed by four-side sealed packaging. In such a four-side sealed package, the length direction of the film F is aligned with the conveyance direction x in a state where the long film F is folded in two or in a state where the two long films F and F face each other. A pair of first heat seals 8 are continuously applied in the direction along the transport direction x of the film F while being transported in the state of being moved, and the second in a direction crossing the transport direction x. The sealing bag 3 is formed on at least four sides, and the packaging bags H in which the constituent material Ma is enclosed are successively formed.
[0024]
The film F to be heat-sealed so as to be able to peel off the interface is, for example, a non-stretched plastic layer 2a, an adhesive film on one surface of a base film 1 formed by stretching a plastic via an adhesive layer 1a. It can be formed by integrally providing a sealant layer 2 composed of three layers of a layer 2b and an unstretched plastic layer 2a. According to this film F, the plastic layer 2a which comprises the said sealant layer 2 in the uppermost surface of the sealant layer 2 of the film part 4 which comprises one surface side of the packaging bag H, and the other surface side of the packaging bag H are comprised. By forming the packaging bag H by heat sealing at a temperature at which the plastic layer 2a constituting the sealant layer 2 on the uppermost surface of the sealant layer 2 of the film part 4 is firmly fused and bonded together, When the film portions 4 and 4 are pulled away from each other, the sealing portion 3 is broken at the contact interface 2c of the double-sided film portions 4 and 4 so that the film portions 4 and 4 on both sides can be easily separated. The (Fig. 6)
[0025]
In addition, the film F that is heat-sealed so as to be delaminated is, for example, an unstretched plastic layer 2a and an adhesive film that are formed from the inside through an adhesive layer 1a on one surface of a base film 1 formed by stretching a plastic. It can be formed by integrally providing a sealant layer 2 composed of three layers of a layer 2b and an unstretched plastic layer 2a. According to this film F, the plastic layer 2a which comprises the said sealant layer 2 in the uppermost surface of the sealant layer 2 of the film part 4 which comprises one surface side of the packaging bag H, and the other surface side of the packaging bag H are comprised. By forming the packaging bag H by applying the heat seal at a temperature at which the plastic layer 2a constituting the sealant layer 2 on the uppermost surface of the sealant layer 2 of the film part 4 is firmly fused and bonded, When the film parts 4 and 4 are pulled away from each other, the seal part 3 is broken in the interlayer 2d between the adhesive film layer 2b and the non-stretched plastic layer 2a constituting the sealant layer 2 in either one of the film parts 4. Thus, the film portions 4 and 4 on both sides can be easily separated. (Fig. 7)
[0026]
The film F that is heat-sealed so as to be capable of cohesive failure is provided with an aluminum foil layer 2e on one surface of a base film 1 formed by stretching a plastic via an adhesive layer 2a. It can be formed by providing a sealant layer 2 made of a heat-weldable adhesive layer 2f that causes cohesive failure on the upper surface of the layer 2e. According to such a film F, when the film portions 4 and 4 on both sides constituting the packaging bag H are pulled in the direction of leaving, the sealant layer 2 in both the film portions 4 and 4 welded by heat sealing is formed. Cohesive failure can be caused in the adhesive layer 2f, and the sealing portion 3 can be broken and the film portions 4 and 4 on both sides can be easily separated. (Fig. 8)
[0027]
The three-side packaging bag H or the four-side packaging bag H is formed by the film F having the sealant layer 2 that is heat-sealed so as to be capable of interfacial peeling, delamination or cohesive failure. Since the packaged food M is provided so as to maintain a plate shape in the state of being enclosed in the packaging bag H, the package on the surface of the plate-shaped food M is simply opened by cutting one side of the packaging bag H. This is because it becomes difficult to smoothly remove the plate-like food M from the packaging bag H due to the close contact of the inner surface of the bag H.
[0028]
That is, if the three-sided packaging bag or the four-sided packaging bag is formed by the film F having the sealant layer 2 that is heat-sealed so as to be capable of interfacial peeling, delamination, or cohesive failure, the three-sided packaging bag is on any side of the packaging bag H. By applying the seal portion 3 so that an unsealed portion 6 is formed between the edge 5 of the film F and the outer edge of the seal portion 3 directed toward the edge 5 of the film F, The sealing part 6 can be easily broken by pulling the film parts 4 and 4 on both sides of the packaging bag H in the direction of separating them with the allowance for peeling off. The two sealing portions 3 and 3 of the packaging bag H adjacent to the sealing portion 3 on the one side are continuously broken, and the film portions 4 and 4 on both sides are separated and sealed on three sides. It is can be taken out Jo food M easily. (FIGS. 9 to 12)
[0029]
The base film 1 in the film F having the sealant layer 2 that is heat-sealed so as to be capable of interfacial peeling, delamination, or cohesive failure is preferably a stretched film made of nylon, polyethylene terephthalate, or polypropylene. This is because stretched films made of nylon and polyethylene terephthalate are excellent in gas barrier properties and rigidity, so that it is difficult for the encapsulated plate-like food M to be altered by contact with the outside air, and during storage and transportation. This is because the film F is hardly damaged. Also, a stretched film made of polypropylene is slightly inferior in gas barrier properties and rigidity to a stretched film made of nylon or polyethylene terephthalate, but can be supplied at a low cost.
[0030]
From the viewpoint of facilitating the opening operation using the unsealed portion 6 of the packaging bag H as a peeling allowance, the edge 5 of the film portion 4 on the one surface side of the packaging bag H is the other surface in the unsealed portion 6. The seal portion on the unsealed portion 6 side in a state where the edges 5 of the film portions 4 and 4 are shifted in position in the unsealed portion 6 so as to be located inside the edge 5 of the film portion 4 on the side. 3 is preferably formed. (FIG. 10) If the edges 5 of the film portions 4 and 4 are displaced in this way, the two film portions 4 in the unsealed portion 6 before the pulling operation for opening is performed. This is because it is easy to hold it.
[0031]
Further, from the viewpoint of facilitating the opening operation using the unsealed portion 6 of the packaging bag H as a stripping allowance, the outer edge of the seal portion 3 on the unsealed portion 6 side is on the unsealed portion 6 side. It is preferable that the seal portion 3 is formed so as to be a mountain-shaped or wave-shaped edge 3a formed so as to have the top portion 3b. (FIG. 13) If such a seal part 3 is formed in this way, when the unsealed part 6 is used as a stripping allowance and the double-sided film parts 4 and 4 of the packaging bag H are pulled away from each other, this pulling is performed. This is because the force can be concentrated on the top portion 3b of the seal portion 3 and the seal portion 3 can be easily broken from the top portion 3b side.
[0032]
The filling of the constituent material Ma of the plate-like food M is typically performed by placing the second heat seal 9 on the inner side of the film F which is formed into a flat cylindrical shape by applying the first heat seal 8. The filling pipe 11 is inserted so that the discharge port 11a is positioned immediately above the heat seal means 16 for applying the heat sealing means 16 and is heated continuously or intermittently through the filling pipe 11 from the discharge port 11a. This can be done by feeding the constituent material Ma prepared in the state of having.
[0033]
In addition, for example, as shown in FIG. 3, the feeding of the constituent material Ma to the filling pipe 11 is performed by a feeding hopper 12a of the constituent material Ma and an extruded pipe portion communicated with the lower end opening 12b of the hopper 12a. 12c and the extruded tube portion 12c are provided at the center of the extruded tube portion 12c so as to extrude into the extruded tube portion 12c by its own weight or forcibly enter the constituent material Ma toward the front end side of the extruded tube portion 12c. The filling device 12 includes a rotary pump 12d, and the front end side of the extruded tube portion 12c communicates with the filling tube 11. (Note that the reference numeral 12e in the figure represents the rotor of the rotary pump.)
[0034]
The first heat seal 8 is composed of a pair of vertical heat rolls 15a and 15a in which the rotation axis is arranged in a direction orthogonal to the transport direction x of the film F as shown in FIG. It can be applied by heat sealing means 15.
[0035]
In the example shown in FIG. 2, the film F drawn from the raw film indicated by reference numeral 13 in the drawing is folded in half by the two-folding means indicated by reference numeral 14, and the film F thus folded is folded. A configuration is adopted in which a pair of the first heat seals 8 are provided along the folding side y side and the side z opposite to the folding side y side. That is, in the example shown in FIG. 2, the pair of longitudinally heated rolls 15 a and 15 a are respectively provided at both ends thereof with the folded side y side and the side z opposite to the folded side y side of the film F folded in half. An annular raised portion 15b having an outer casing shape that continuously applies the first heat seal 8 along the transport direction x of the film F while pulling in and feeding out the film F is provided at the edge of Yes.
[0036]
Then, the pair of vertical heat rolls 15a and 15a are arranged so that the raised portions 15b are brought close to the raised portions 15b of the other vertical heated rolls 15a on the side facing the other vertical heated roll 15a. The heat sealing means 16 for drawing the film F folded in half between the adjacent raised portions 15b from the side of the double folding means 14 and applying the second heat seal 9 to the drawn film F. It is set as the structure rotated in the reverse direction with respect to the other vertical heat roll 15a so that it may send out to the side of this.
[0037]
The second heat seal 9 is composed of a pair of transverse heat rolls 16a and 16a in which the rotation axis is arranged in a direction perpendicular to the transport direction x of the film F as shown in FIG. It can be applied by heat sealing means 16.
[0038]
In the example shown in FIG. 2, the pair of transverse heat rolls 16a and 16a draws the film F into the film F to which the first heat seal 8 has been applied by the pair of vertical heat rolls 15a and 15a. In addition, a protruding portion 16c that sequentially applies the second heat seal 9 with a predetermined interval while being fed out is provided in a protruding shape along the rotational axis direction of the transverse heat roll 16a.
[0039]
In this embodiment, the transverse heat roll 16a has outer flange-shaped portions 16d on both ends thereof, and has the ridge portion 16c between the outer flange-shaped portions 16d. Yes. In the present embodiment, the protrusions 16c are formed at a plurality of positions at intervals in the rotational direction of the transverse heat roll 16a. And the protrusion 16c of a pair of transverse heating rolls 16a, 16a is the protrusion of the other transverse heating roll 16a sequentially on the side facing the other transverse heating roll 16a as the transverse heating roll 16a rotates. As a configuration in which the second heat seal 9 is intermittently applied by the protrusion 16c to the long film F which is brought close to the part 16c and is drawn between the pair of transverse heat rolls 16a and 16a. is there.
[0040]
Next, in the second step, degassing is performed by pressing the film F so as to spread the filled constituent material Ma until the second heat seal 9 applied in the next order is applied. Step 20.
[0041]
This deaeration step 20 is first performed until the second heat seal 9 is applied, in which the air contained in the constituent material Ma filled in the filling step 10 is given in the next order. This is done to remove as much as possible from the constituent material Ma so that excess air does not remain in the constituent material Ma enclosed in the packaging bag H. Second, the tip in the film F formed into a flat cylindrical shape by the first heat seal 8 until the second heat seal 9 applied in the next order is applied. The constituent material Ma is densely distributed in the space up to the formation position of the second heat seal 9 applied in order and the second heat seal 9 applied in the next order, and applied in this order. This is done so that air caused by the filling gap does not remain in one packaging bag H formed by applying the second heat seal 9.
[0042]
By this deaeration step 20, the constituent material Ma can be sealed in a state where extra air is prevented from entering the packaging bag H as much as possible, and molding is performed from the constituent material Ma caused by such air. It is possible to prevent the plate-like food M from being altered as much as possible.
[0043]
In the example shown in FIG. 1 and FIG. 2, the rotation axis is in the direction perpendicular to the transport direction x of the film F between the discharge port 11 a of the filling tube 11 and the pair of transverse heat rolls 16 a and 16 a. The pair of squeezing rollers 21 and 21 facing each other are provided in two sets on the top and bottom, and the film F filled with the constituent material Ma passes between the pair of squeezing rollers 21 and 21 to perform the deaeration step 20. It is like that. That is, in this example, the film F filled with the constituent material Ma is pressed by the pair of squeezing rollers 21 and 21 so as to spread the constituent material Ma in the film F and squeeze out. Thus, before forming the second heat seal 9 in which the air contained in the constituent material Ma supplied from the filling tube 11 is applied in the next order by the pair of transverse heat rolls 16a, 16a. It is intended to escape upward.
[0044]
Next, in the third step, the plate-like plate-like food M is averaged so as to spread the component material Ma filled in the packaging bag H by pressing the packaging bag H filled with the component material Ma. It is the shaping | molding process 30 shaped into.
[0045]
This forming step 30 is first performed by applying the constituent material Ma filled in the packaging bag H to a plate shape following the internal space 7 of the packaging bag H, more specifically, to the packaging bag H. It is made to form a plate-like food M having a plate shape following the flat and square inner space 7 formed by the inner edge of the first heat seal 8 and the inner edge of the second heat seal 9. . Since the first heat seal 8 and the second heat seal 9 can be regularly formed by the vertical heat roll 15a and the horizontal heat roll 16a, each packaging bag H that is continuously formed, Each of the plate-like foods M, M,... Enclosed in H... Is a uniform plate-like food M that is substantially equal, and can stably supply the same standard product. In the three-side sealed packaging bag and the four-side sealed packaging bag, the first heat seal 8 along the transport direction x of the film F is separately provided at one or more places between both sides of the packaging bag H. In some cases, the packaging bag H is formed so as to have two or more internal spaces 7, 7..., And in this case, two or more plate-like foods M that form a rectangular plate shape in one packaging bag H. Can be molded and encapsulated. The first heat seal 8 for forming two or more internal spaces 7 of the packaging bag H is provided with a bowl-shaped raised portion 15b as described above at an intermediate portion between the pair of vertical heat rolls 15a and 15a. Can be formed. In addition, if the heat seals 8 and 9 are applied so that the corners formed by the inner edges of the heat seals 8 and 9 are rounded, the plate-like food having a plate shape with slightly rounded corners. M can be molded.
[0046]
In addition, secondly, the forming step 30 is configured such that the constituent material Ma filled in the packaging bag H is a plate-like food M having a plate shape. Can be appropriately cooled and solidified in a short time.
[0047]
In the example shown in FIG. 1 and FIG. 2, a pair of leveling rollers 31 having a rotation axis directed in a direction perpendicular to the transport direction x of the film F at the next rank position of the pair of transverse heating rolls 16 a, 16 a, 31 is formed in a continuous state between the pair of leveling rollers 31, 31, and the packaging bag H enclosing the constituent material Ma passes through the interior space of the packaging bag H by the leveling roller 31. 7 is formed so that the constituent material Ma is spread over the entire surface with a uniform thickness.
[0048]
In the example shown in FIGS. 1 and 2, a feed roller 32 that conveys the packaging bag H formed in a continuous state is provided at the next rank position of the pair of leveling rollers 31, 31. A cutting means 33 for cutting the packaging bag H formed in such a continuous state at the next rank position of the feed roller 32 within the width of the second heat seal 9 and dividing the packaging bag H into individual packaging bags H is provided. It is provided.
[0049]
Then, by this cutting means 33, the cut packaging bag H slides down on the guide plate 34, and on the end 35 a on the load receiving side of the belt conveyor 35 that feeds the packaging bag H one by one into the cooling device 41 described later. It is configured to be sent to. (Fig. 4)
[0050]
Further, in the example shown in FIGS. 1 and 2, the belt conveyor 35 is provided with a circling belt 36 a arranged so as to press the lower surface against the packaging bag H conveyed by the belt conveyor 35 from above. A pressing means 36 is provided. (FIGS. 1 and 4) Even between the pressing means 36 and the belt conveyor 35, the constituent material Ma is uniformly distributed in the entire internal space 7 of each packaging bag H, H. In the example shown in FIGS. 1 and 2, the pressing means 36 also executes the molding step 30.
[0051]
Next, the fourth step is a cooling step 40 in which the packaging bag H containing the plate-like food M that has been flattened into a plate shape is heated to keep the plate-like food M in shape.
[0052]
The cooling step 40 keeps the plate-like food M, which is formed in the packaging bag H and formed by forming the constituent material Ma into the substantially rectangular plate shape in the molding step 30 in the substantially square plate shape. It is made in order to be able to provide the final consumer up to the stage of eating.
[0053]
Such cooling is performed, for example, by feeding the packaging bag H into the cold water cooling device 41.
[0054]
FIG. 5 shows that the belt conveyor 42 that receives and conveys the packaging bag H from the end 35b on the unloading side of the belt conveyor 35 is conveyed while the packaging bag H is immersed in the cooling tank 41a in which cold water is stored. An example in which such heating is performed by the cold water cooling device 41 arranged in FIG. In the figure, reference numeral 43 denotes a pressing travel belt that travels in the same direction as the belt conveyor 42 with its lower surface positioned on the belt conveyor 42 in the cooling tank 41a of the cold water cooling device 41. The press traveling belt 43 prevents the packaging bag H, which is conveyed on the belt conveyor 42, from being lifted in the cooling tank 41a.
