Description

Improved food processor with slag collecting function

Technical Field

The invention relates to the technical field of food processing devices, in particular to an improved food processor with a dreg collecting function.

Background

Food processing is a common occurrence in people's daily lives, such as cleaning, cooking, crushing, squeezing, etc. of food. Wherein, the pulverization of food is mainly the pulverization of beans, cereals, chinese medicines, etc., the pulverization is for pulverizing food into smaller particles, for example, beans are mixed with water, pulverized and decocted to extract to prepare soybean milk, and the Chinese medicines are pulverized and then extracted by water to extract the effective components; the squeezing of food is mainly the squeezing of fruits and the like, and is to squeeze the food out of juice, for example, the juice can be made into freshly squeezed juice after the fruit is squeezed, the juice can be made into freshly squeezed vegetable juice after the vegetable is squeezed, and the like.

The positive displacement food processor in the prior art can be used for extracting nutritional ingredients after crushing and decocting beans, and can also be used for extracting juice after crushing fruits and vegetables. Food processors of this type generally comprise a motor, a cutter shaft, a cutter, a tub, a body and an electronic control device, rotation of the cutter breaking up the food or a mixture of food and water in the tub into a food liquid.

Generally, fruits, vegetables (or fish, etc.) and the like are pulverized into a food liquid by a cutter of a food processor, and then are roughly divided into two parts, namely, a "water-soluble substance" and a "water-insoluble substance". "Water-insoluble material" is colloquially referred to as "sludge". Most of these residues are something that has a rough mouthfeel and cannot (or is difficult to) be absorbed by the human body. The residue still contains a large amount of liquid, and even if the residue is filtered for a long time, the residue still contains a large amount of liquid, usually about 1 to 5 times of the dry weight of the residue, and the liquid such as fruit juice or soybean milk contained in the residue is wasted.

Food processors in the prior art generally have the problem that the slag is troublesome to handle. In order to solve the slag treatment problem, various solutions are proposed in the prior art.

Patent document CN204192427U proposes a high-speed wall-breaking extraction device for fresh edible medicinal materials, the device comprises an extraction cup, a centrifugal cup, a high-speed motor, an extraction blade, a control module and the like, the centrifugal cup is arranged in the extraction cup, and a filter hole is arranged on the wall of the centrifugal cup. In one embodiment, a clutch is connected between the motor and the extraction blade, the bottom of the centrifugal cup is connected with the clutch, the rotation process of the extraction blade and the rotation process of the centrifugal cup are switched through the clutch, the extraction blade is started to carry out the basic crushing process, and after the crushing is completed, the high-speed motor is started to drive the centrifugal cup. The bottom of the centrifugal cup is closed, the crushing process is completed in the centrifugal cup, the centrifugal cup has larger volume, and the foodstuff liquid is formed in the centrifugal cup and is communicated with the extraction cup through the hole of the cup wall. The scheme has a plurality of defects that firstly, how to arrange holes on the wall of the cup is not disclosed, if the holes are arranged more upwards, spin-drying cannot be realized in practice, if the holes are lower, the centrifugal cup is communicated with the extraction cup during centrifugal operation, and if the spin-drying function is used, juice in the extraction cup is taken out from a liquid taking port, so that the spin-drying function can be realized only by starting up and stopping for a plurality of times, and the operation is complicated; secondly, the extraction cup cover, the centrifugal cup cover and the like are all required to be cleaned, the centrifugal cup is large in size and porous, the extraction cup comprises a liquid taking channel, a plurality of parts are required to be cleaned, and the cleaning is difficult; finally, the extraction blade must be placed in the centrifugal cup, and both the extraction blade and the centrifugal cup must be disassembled during cleaning, so that the disassembly and assembly are inconvenient. In this embodiment, since the centrifugal cup is a space for pulverizing the edible medicinal material, the centrifugal cup is large in size and weight, and particularly, it is required to avoid rotation of the centrifugal cup during pulverization, particularly, in an initial stage of pulverization, rotation of the centrifugal cup is not desirable even more when the edible medicinal material is solid and the edible medicinal material such as fruit is pulverized, and to avoid rotation of the centrifugal cup during pulverization, the centrifugal cup is connected to the extraction blade and the centrifugal cup through the clutch, respectively, so that rotation of the centrifugal cup is controlled. In another embodiment which does not comprise a clutch, the centrifugal cup is arranged separately from the extraction blade, during crushing, the extraction blade is taken down during centrifugation in the extraction cup, the centrifugal cup is installed, the food liquid is poured into the centrifugal cup, the motor is started again, and the centrifugal cup is driven to perform centrifugal treatment.

Patent documents WO2018/171370A1 and CN106943039a respectively disclose a food processor with a slag collecting function, wherein a diversion component and a separation part with hollow structures are arranged in a barrel body, a diversion port is arranged at the lower part of the diversion component, and a liquid outlet is arranged at the separation part. During operation, the crushing step is carried out in the barrel body, the cutter and/or the pump-like mechanism is used for driving the food liquid, so that the food liquid enters the guide component from the guide port and is conveyed to the separating part, the juice flows out from the liquid outlet, the material slag is collected in the separating part and circularly reciprocates, the separation of the material slag and the juice is realized, the crushing and separating steps can be carried out simultaneously or in different time periods, and in some embodiments, the drying step is further carried out. The work mainly comprises a crushing step, a slag collecting step (in certain embodiments, the crushing step and the slag collecting step are carried out simultaneously) and a spin-drying step, and the method comprises the following steps of:

crushing: the cutter shaft drives the cutter to rotate, so that the cutter pulverizes foodstuff;

Slag collection: the foodstuff liquid in the barrel body is driven by the cutter and/or the pump-like mechanism to pass through the flow guide opening of the flow guide part or enter the separation part from the liquid inlet of the separation part when the flow guide part is not provided, the liquid in the foodstuff liquid is discharged out of the separation part from the liquid outlet, and at least part of the material slag in the foodstuff liquid is collected in the separation part.

And (3) spin-drying: the material slag in the separation part is spin-dried, the motor can drive the separation part in the barrel body (directly driven or driven by the flow guide component and the like) to rotate through the cutter shaft, the food liquid is blocked outside the separation part, and liquid contained in the material slag in the separation part is thrown out from the liquid outlet, so that at least part of liquid in the material slag is thrown out.

However, the inventor found in practice that since the cutter of the food processor is still driven by the motor in the spin-drying step, the rotation speed of the cutter shaft is as high as 3 ten thousand rpm or more, even as high as 5 ten thousand rpm, even though the liquid level is lower than the separating portion of the separating portion when the food liquid is stationary, the food liquid is vigorously tumbled in the tub due to the agitation of the cutter rotating at high speed and mixed with a large amount of air, the volume of the air-liquid mixture is increased, and the liquid level is raised (even the whole space in the tub is filled) due to the combined action of the agitation and the tumbling, so that the food liquid is continuously raised to the height of the separating portion and enters the separating portion through the liquid outlet of the separating portion, thereby resulting in poor material dreg spin-drying effect.

Detailed Description

The present invention will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present invention more apparent. Those skilled in the art will recognize that the present invention is not limited to the drawings and the following examples.

The present invention incorporates by reference the entire patent document international publication number WO2018/171370A1 as part of the present invention.

The present invention is not related to improvements in knives in food processors. The cutter refers to a crushing cutter device or a general term of a crushing device of a food processor, and the cutter can be driven by a motor of the food processor to rotate or rotate so as to crush foodstuff. The cutter in the invention is the existing cutter and comprises a collision type crushing cutter, a shearing type crushing cutter, a grinding device with a matched dynamic grinding head and a static grinding head, and the like. Wherein in particular the shear-type crushing cutter comprises a main cutter, which is the main part, which is arranged on and driven by the arbor, and a counter cutter, which is not driven by the arbor (or is not driven mainly by the arbor; in most cases the counter cutter is stationary, is freely rotatable, and is also counter to the direction of rotation of the main cutter). The working state of the main cutter is mainly focused on the shearing type crushing cutter, and the matched cutter is not described. For example, when the cutter is rotated in the present invention, if the shear crushing cutter is referred to, the expression describes a state in which the main cutter is rotated, and the description of the auxiliary cutter is omitted. The grinding device with the matched dynamic grinding head comprises a dynamic grinding head and a static grinding head, wherein the dynamic grinding head is a main part, the dynamic grinding head is arranged on the cutter shaft and driven by the cutter shaft, and the static grinding head is not driven by the cutter shaft (or is not driven by the cutter shaft mainly. The working state of the movable grinding head of the grinding device matched with the movable grinding head is mainly focused on, and the static grinding head is not described.

When the cutter is a shear crushing cutter: the motor can drive the cutter in the barrel body through the cutter shaft, which also means a main cutter of the shearing type crushing cutter driven by the motor through the cutter shaft, and comprises the motor which directly drives the cutter in the barrel body through the cutter shaft and the cutter in the barrel body driven by the motor through other transmission devices.

The cutter is connected with the cutter shaft through a cutter clutch. In the present invention, the term "the cutter is connected to the cutter shaft through the cutter clutch" means that the main cutter is connected to the cutter shaft through the cutter clutch "as used in the present invention.

When the cutter is a grinding device with a matched dynamic grinding head and a static grinding head: the motor can drive a cutter in the barrel body through the cutter shaft, which means a movable grinding head of a grinding device matched with the movable grinding head through the cutter shaft, and the motor not only comprises the motor which directly drives the movable grinding head in the barrel body through the cutter shaft, but also comprises the motor which drives the movable grinding head in the barrel body through other transmission devices.

The cutter is connected with the cutter shaft through a cutter clutch. In the invention, for a grinding device with a matched dynamic grinding head and a static grinding head, the expression that a cutter is connected with a cutter shaft through a cutter clutch means that the dynamic grinding head is connected with the cutter shaft through the cutter clutch.

A food processor is a device that performs food processing. The foodstuff in the invention is a food material which can be processed by a food processor, such as fresh fruits, vegetables, traditional Chinese medicine materials, grains and the like. In general, the foodstuff may be mixed with water, for example, "apple+water" together with apple juice or the like. In the food processor of the invention, when the cutter rotates, the food in the barrel is processed to form the food liquid with the food residues, which means that: the knife breaks up food materials such as fruits and the like in the barrel body and water into food liquid with slag when rotating. Of course, the food material having a large water content may be directly crushed into a food liquid with slag. The foodstuff with high water content refers to foodstuff with high water content, such as fresh grape, cucumber and the like. Or pulverizing the Chinese medicinal materials together with wine (Chinese liquor, grape wine or yellow wine, etc.), and making into medicated liquor (after pulverizing the Chinese medicinal materials in wine, more beneficial to dissolving out the effective components in the medicinal materials), for example, pulverizing 20g radix astragali together with 500 g Chinese liquor, and making into radix astragali medicated liquor.

The food liquid obtained after processing is the solid-liquid mixture of juice and slag. In strict terms, the juice itself is also a solid-liquid mixture, and the juice generally contains solid scraps with smaller particles, but the scraps are in a liquid state relative to the slag, so that the terms "juice" and "liquid" in the specification are used for convenience in description to refer to the part of the food liquid after the slag is removed. The slag referred to in the present invention means "solid particles which cannot be discharged through the liquid outlet of the separation section, or solid particles having a particle diameter larger than that of the liquid outlet (or the filtering hole of the filter screen)".

For convenience of description of the text and the drawings, the rotation direction of the cutter is assumed as follows: the forward rotation of the cutter is to crush foodstuff, and the process is prior art and will not be described in detail.

All references to "forward rotation" and "reverse rotation" in this invention are relative terms. Such as "motor forward rotation", "motor reverse rotation", "tool forward rotation", "tool reverse rotation", "separation forward rotation", "separation reverse rotation", etc., are defined for convenience of clarity of description of the "rotational direction of the respective members". Forward and reverse rotation are merely indicative of the direction of rotation and the operational condition of the corresponding components of the food processor of the present invention. Either one of the clockwise or counterclockwise rotation directions may be defined as "forward rotation" according to the actual need or the structural feature of the embodiment, and then the opposite direction to the "forward rotation" is "reverse rotation".

However, in the same food processor, the definition of the forward and reverse directions of all rotating parts must be identical. For example, when the counterclockwise rotation direction of the cutter shaft is defined as a normal rotation, then the counterclockwise rotation direction of other rotating members such as a shutter, a separating portion, etc. is also defined as a normal rotation. On the contrary, when the clockwise rotation direction of the definition knife shaft is forward rotation, the clockwise rotation direction of other rotating parts such as the blocking piece, the separating part and the like is also forward rotation.

However, in different embodiments of the invention, the definition of forward or reverse rotation may be different.

In the invention, the cutter clutch comprises an overrunning clutch and an electric control clutch, and also comprises an axial displacement clutch mechanical structure which can enable the cutter to axially displace along the cutter shaft based on the change of the rotation direction of the cutter shaft so as to realize the switching between the cutter and the cutter shaft in the connection state and the separation state; the electric control clutch comprises an electric control clutch commonly used in the field and also comprises an electric locking clutch mechanism or an electromagnetic locking clutch mechanism based on the mutual matching of a cutter shaft and a cutter.

Example 1

Referring to fig. 1a, the present embodiment proposes a food processor with a slag collection function, comprising a motor 1, a cutter shaft 2, a cutter 3, a separating part 4, a tub 5, a machine body 6 and a controller; the motor 1 is arranged in the machine body 6, the separating part 4 is connected with the cutter shaft 2, the cutter 3 is connected with the cutter shaft 2 through the cutter clutch 7, and the motor 1 can drive the cutter 3 and the separating part 4 which are positioned in the barrel body 5 through the cutter shaft 2; the cutter clutch 7 has an engaged state and a disengaged state, and the controller is used for controlling the operation of the food processor, for example, the controller can control the rotation direction, rotation speed and the like of the cutter shaft, and for example, the controller can control the cutter clutch 7 to switch between the engaged state and the disengaged state, when the cutter clutch 7 is in the engaged state, the cutter 3 is driven by the motor 1 to rotate along with the rotation of the cutter shaft 2, and when the cutter clutch 7 is in the disengaged state, the power transmission between the cutter shaft 2 and the cutter 3 is released, and the motor 1 no longer drives the cutter 3; in the pulverizing step, the cutter clutch 7 is in an engaged state, and the cutter 3 processes foodstuff in the tub 5 while rotating, forming a foodstuff liquid with a residue. Preferably, the separating portion 4 is detachably connected to the arbor 2.

The separating portion 4 has a hollow structure having a side wall, for example, a cylindrical hollow body made of stainless steel. The separation part 4 has a liquid outlet hole 41 (see fig. 1b for the arrangement of the liquid outlet hole 41), for example, a hole opened in the side wall of the separation part 4, or a screen having the liquid outlet hole 41 is arranged at the hole opened in the side wall of the separation part 4. Optionally, the separating portion 4 has a bottom surface, and the bottom surface and/or the side wall of the separating portion 4 are provided with a liquid inlet 42 serving as an inlet for the food liquid. Preferably, the separating portion 4 has a top cover 43 (the arrangement of the top cover 43 is referred to in fig. 1 b), more preferably, the top cover 43 is a detachable top cover 43. The setting top cap can avoid getting into the material sediment of separation portion 4 and be taken out by the foodstuff liquid, sets up the removable top cap and is convenient for get the material sediment, also is convenient for wash separation portion 4.

When the cutter 3 rotates, the food liquid in the barrel 5 can enter the separation part 4 from the outside of the separation part 4 through the liquid inlet 42 under the drive of the cutter 3, the liquid in the food liquid is discharged out of the separation part 4 from the liquid outlet 41, at least part of the slag in the food liquid is collected in the separation part 4, the cutter clutch 7 is in a separation state in a spin-drying step, the separation part rotates along with the rotation of the cutter shaft, and at least part of the liquid in the slag collected in the separation part 4 can be thrown out.

In the step of collecting the slag, in order to enable the cutter to drive the food liquid to enter the separating part when rotating, various schemes can be adopted, for example, the blade of the cutter is in an axial flow blade shape, through setting the angle of a proper blade, the cutter can generate axial pressure from bottom to top on the food liquid when rotating, the food liquid flows from the outside of the separating part to the inside due to the conduction effect of liquid pressure, the food liquid enters the separating part, the liquid in the food liquid is discharged from the liquid outlet to the outside of the separating part, and at least part of the slag in the food liquid is collected in the separating part. Such tools are well known to those skilled in the art and will not be described in detail. It should be noted that, in the crushing step and the slag collecting step, the rotation directions of the cutters may be the same or different; the pulverizing step and the slag collecting step may be performed simultaneously or separately, for example, when the cutter is an axial-flow blade cutter, the pulverizing step and the slag collecting step may be separated by different rotation directions, or may be rotated in one direction to combine the pulverizing step and the slag collecting step.

When the food processor is in use, the liquid inlet of the separation part can be positioned above the liquid level when the food liquid is stationary (a certain distance exists between the liquid inlet and the liquid level), or can be positioned at least partially below the liquid level when the food liquid is stationary. When the cutter rotates at a high speed, the axial pressure of the axial flow pump generated by the cutter is enough to be high enough to enable the food liquid to flow fast enough, and at the moment, even if the liquid level of the food liquid is lower than the liquid inlet when the food liquid is static, the food liquid mixed with a large amount of air and vigorously rolled in the barrel body can still enter the separation part.
