The present invention relates to a peanut peeler that minimizes damage to seeds during peeling of peanuts, has excellent peeling efficiency, and minimizes the generation of scattering dust.

Peanuts are harvested in the field and then distributed as blood peanuts in the shell state and sold to consumers, but they are made in the state of peeled peanuts and distributed as they are, used as seeds, or distributed as various processed foods.

Peanuts are wrapped in a hard cuticle in the state of being cultivated and collected, and the thin peel-like shell inside is double-protected.

Peanuts are generally distributed in a state in which the outer shell is removed during the sale and distribution process.

In general, in the case of farmhouses or factories that consume a large amount of peanuts, a peanut peeler that performs mechanical continuous work is used to remove the outer cuticle.

Conventional peanut peelers remove hard cuticles by passing peanuts between a pair of metal rollers or by applying pressure from the outside, but the shape and size of the outer cuticles are very diverse, while the mechanical peelers work at the same intensity and speed, resulting in peanut The cuticle of the plant was not removed efficiently or the seeds were continuously damaged due to strong impact.

Therefore, even when the cuticle is removed using a conventional peanut peeler, it has a high damage rate and has a low germination rate, which makes it difficult to use as a seed. there was.

In addition, when the peanut peeler is used, there is a problem in that the powder of the removed cuticle, sand and dust mixed with the peanut are scattered, and the working environment is poor and the health of the worker is adversely affected.

Therefore, the present inventors have completed the present invention as a result of diligent efforts to develop a peanut peeler capable of minimizing seed damage and scattering dust as well as excellent separation efficiency.

Hereinafter, embodiments of the present invention will be described in detail, but it is obvious that the present invention is not limited by the following examples.

One aspect of the present invention, the body housing 160 including an inner space; A semi-cylindrical peeling drum 110 located inside the body housing 160 and having a curved lower end; At least one pressing member 120 protruding in the longitudinal direction along the rotating shaft 111 at the lower end of the peeling drum 110; a rotating member 130 connected to the rotating shaft 111 of the peeling drum 110; a blowing member 140 provided to flow gas along at least one flow line at the lower end of the peeling drum 110; It provides a peanut peeler 100 comprising a; and a filter plate 150 disposed at the bottom of the peeling drum 110 at predetermined intervals and having a plurality of holes.

The peanut peeler 100 is a device for removing the skin of the peanuts and separating the peanuts, and operates manually without a separate power source that provides rotational force to the peeling drum 110, or connects an external power source. so it can work.

For example, the peanut peeler 100 can manually or automatically operate the peeling drum 110 through the rotating member 130 to effectively remove the cuticle of the peanut without damaging the seeds.

The rotating member 130 may be provided with a grip part that can be manually operated by a user, or may be provided with an external power source such as a motor to automatically provide rotational force.

The peanut peeler 100 may remove the cuticle through the pressing member 120 protruding outside the peeling drum 110, and at this time, the pressing member 120 having elasticity may be applied to prevent damage to the seeds. there is.

The pressure member 120 may apply pressure to the peanuts located on the filter plate 150 by a pendulum motion of the peeling drum 110 .

The peeling drum 110 of the peanut peeler 100 performs a pendulum movement by the user's manipulation, and the pressing member 120 protruding to the lower end of the peeling drum 110 is located on the filter plate 150. can apply pressure.

Referring to FIG. 1 showing an example, the peanut peeler 100 includes a body housing 160, a peeling drum 110, a pressing member 120 protruding from the lower end of the peeling drum 110, the peeling drum ( 110) A rotating member 130 connected to the rotating shaft 111, a cover housing 161 in contact with at least a part of the upper end of the main body housing 160, connected to the cover housing 161 and at the lower end of the peeling drum 110 A blowing member 140 provided to flow gas along at least one oil line, an input housing 162 in contact with the remaining part of the upper end of the main body housing 160, and the lower end of the peeling drum 110 at predetermined intervals. It may include a disposed filter plate (150).

The body housing 160 may include a predetermined space therein, and may include a series of components for separating peanuts from peanuts.

At least a part of the upper portion of the main body housing 160 is open, and peanuts to be separated may be introduced.

The cover housing 161 is in contact with at least a portion of the upper portion of the main body housing 160, to prevent the inflow of foreign substances when the peanut peeler 100 is not in use, and to open the upper portion of the main body housing 160 only when in use. However, this cover housing 161 is not essential to the peanut peeler 100.

When the cover housing 161 opens the upper part of the body housing 160, the entire cover housing 161 is opened (FIGS. 2, 3, and 5) or a part of the cover housing 161 is opened. (FIG. 1, FIG. 6) it is possible to secure the input route of the peanuts.

The input housing 162 is in contact with the remaining part of the upper part of the main body housing 160, and has a ramp therein so that the peanuts can be continuously input, but this input housing 162 is the peanut peeler 100 ) is not essential to the configuration.

The body housing 160 includes a peeling drum 110 that performs a pendulum movement therein, and after introducing a target to be separated into the body housing 160, the cuticle is pulverized by manipulating the peeling drum 110. can make it

The "pendulum motion" is to vibrate at a constant cycle based on one fixed axis, and the peeling drum 110 repeats a back and forth motion to crush the cuticle of the peanut located at the lower end of the pressing member 120 at the lower end. can (Fig. 2).

The peeling drum 110 is located inside the body housing 160, and a lower end thereof may form a curved surface.

The peeling drum 110 may have a semi-cylindrical shape, and a central portion of the semi-cylinder may be connected to the rotation shaft 111 so as to perform a pendulum motion based on the rotation shaft 111 .

In one embodiment, since the peeling drum 110 may have a semi-cylindrical structure, it may be semi-circular when viewed from one side (FIG. 1) and may be rectangular when viewed from the other side (FIG. 3), and the lower end may form a curved surface. can

However, the peeling drum 110 does not necessarily have to be a semi-cylindrical shape, and is not particularly limited as long as it is in the form of a column capable of pendulum motion, such as a curved lower end.

In one embodiment, the vibration caused by the pendulum motion of the peeling drum 110 is transmitted to the input housing 162 to sequentially input the blood peanuts.

The pressing member 120 serves to crush the cuticle by applying pressure to the peanut located at the bottom, and may protrude in the longitudinal direction along the rotating shaft 111 at the lower end of the peeling drum 110.

The peeling drum 110 has a columnar shape and performs a pendulum motion based on the rotating shaft 111, and since the pressing member 120 protrudes in a longitudinal direction parallel to the rotating shaft 111, it is positioned on the lower filter plate 150. You can continuously pressurize blood peanuts.

The peeling drum 110 can be operated by applying force directly by the user without a separate power source through the rotating member 130 or by connecting to an external power source.

The rotating member 130 may be connected to the rotating shaft 111 to apply rotational force to the peeling drum 110 .

In one example, the rotation member 130 may include a grip portion applied with a material having high frictional force to prevent slipping as a handle portion, and the user may hold the grip portion with his hand and operate the peanut peeler 100 .

The grip part may be a cylindrical rod that is vertically connected to the rotating shaft 111 of the peeling drum 110 and transmits the user's force, or may be a metal material that does not bend or break even with strong force.

When the user applies force back and forth through the rotating member 130, rotational force is transmitted to the rotating shaft 111, and the peeling drum 110 is directed to the rotating shaft 111 in a direction opposite to the direction of the force applied by the user can exercise with

In another example, the rotating member 130 may include a power source such as a motor for imparting rotational force.

The power source serves to repeatedly perform pendulum motion within a predetermined angular displacement, for example, in the range of 15º, 30º, 45º, 60º, 75º, 90º, 105º, 120º, 135º, 150º, 165º, 180º, etc. The peeling drum 110 may be pendulum-moved by applying rotational force to the rotating shaft 111 .

The filter plate 150 serves to filter the peanuts from which the cuticles are removed to the lower end, and is disposed at the lower end of the peeling drum 110 at predetermined intervals and may have a plurality of holes.

Since the filtering plate 150 can be located at the lower end of the peeling drum 110 at a predetermined interval, the peanuts to be separated can be located in the space between the peeling drum 110 and the filtering plate 150, , The pressing member 120 may repeatedly reciprocate between the spaces and crush the peanuts (FIG. 2).

The filtering plate 150 may include a plurality of holes having an area smaller than that of the peanuts and larger than that of the peanuts, and the peanuts separated from the peanuts are separated to the lower end through the holes of the filtering plate 150. It can be.

An outlet 170 for moving the separated peanuts to the outside may be located at the bottom of the filter plate 150, and the peanuts separated by the peeling drum 110 have a predetermined slope through the outlet 170 You can naturally slide and move along the outside.

The peanut peeler 100 may include a pressing member 120 having elasticity to minimize damage to seeds (peanuts) while crushing the cuticle of the peanut through the pressing of the pressing member 120.

The pressing member 120 may be used without particular limitation as long as the material has a certain level of elasticity or higher. For example, in the group consisting of EPDM (ethylene propylene diene monomer), silicone, urethane, thermoplastic elastomer, and thermoplastic rubber and polypropylene One or more may be selected, but may be preferably made of silicone or rubber.

The hardness of the pressing member 120 can be appropriately controlled so as not to cause damage to the peanuts at the same time as crushing the cuticles of the peanuts. For example, Shore Hardness (shore A) may be 60 to 80 .

If the hardness of the pressing member 120 is too low, the cuticle cannot be efficiently removed, and if the hardness of the pressing member 120 is too high, damage to the peanuts may occur.

Referring to FIG. 4 , the lower end of the pressing member 120 may form a gentle curved surface.

The lower end of the pressing member 120 is an area in contact with the target peanut to be separated, and if it is angular, the target to be separated does not intervene between the pressing member 120 and the filter plate 150, and even if the seed is not pressurized or is pressurized, the seed is damaged. This can be caused, so it can be appropriately curved.

The pressure member 120 has a structure that protrudes from the lower end of the peeling drum 110, and the size may vary in consideration of the characteristics of the product, and the width (w) and height ( h) can be properly controlled.

Meanwhile, one or more pressing members 120 may be formed along the curved surface of the lower end of the peeling drum 110, and the number may vary in consideration of product characteristics or the area of the peeling drum 110.

Referring to FIG. 5 , the pressing member 120 may be composed of a first pressing member 121 located at the center and a second pressing member 122 located at the outer side, and the second pressing member 122 is It may protrude more than the first pressing member 121 .

The first pressing member 121 is located in the center, that is, the lowermost part, and the second pressing member 122 is located in the outer part, and can continuously press the peanuts according to the pendulum motion of the peeling drum 110. In addition, since the size and shape of peanuts to be separated are very diverse, the degree of protrusion may be varied to supplement the pressing strength between the pressing members 120.

The first pressing member 121 is an area for mainly removing the cuticles of peanuts, and the cuticles of peanuts not crushed by the first pressing member 121 are relatively more protruding second pressing members 122 can be crushed by

Also, the second pressing member 122 may have a higher Shore A hardness than that of the first pressing member 121 .

Since the first pressing member 121 is an area for mainly removing the cuticles of peanuts, the cuticles of peanuts that are not pulverized by the first pressing member 121 are relatively hard, the second pressing member 122 can be crushed by

The second pressing member 122 may assist or supplement the first pressing member 121, and by varying the protrusion degree and hardness of the first pressing member 121 and the second pressing member 122, the seeds damage can be minimized.

The pressure member 120 can be independently adjusted in height, and the pressure applied to the peanut can be controlled by varying the height of the pressure member 120.

Since the pressure members 120 can individually change their height and are arranged sequentially, the height of the predetermined area is relatively high and the height of the remaining areas is set relatively low to improve the efficiency of peeling or the rate of damage to seeds. You can control it.

A structure for changing the height of the pressing member 120 may be implemented through various mechanical means in the art.

In one embodiment, the pressing member 120 may include a groove therein, may be coupled to each other through a connecting rod fixed to the peeling drum 110, and the height of the pressing member 120 through a height adjustment screw. It may be a structure in which the height is changed.

However, the structure for changing the height of the pressing member 120 is not particularly limited, and if necessary, a motorized means such as changing the height through an electric motor may be employed.

When using a peanut peeler, sand and dust mixed in when harvesting peanuts and dust generated when removing the cuticle of peanuts may cause scattering dust, resulting in deterioration in usability.

The blower member 140 can suppress the generation of scattering dust by flowing gas along at least one flow line at the lower end of the peeling drum 110 .

For example, the blowing member 140 blows gas in a certain direction to the lower end of the peeling drum 110 to form a direct flow, or at least through an inclined plate (not shown) provided inside the cover housing 161. A flow expressed as a single flow line can be formed.

The blowing member 140 induces dust scattered in irregular directions to have directionality, and by colliding dust particles, it is possible to suppress irregular scattering of dust through mutual aggregation.

Although the drawings of this specification show that the blowing member 140 is connected to the cover housing 161 as an example, the blowing member 140 can flow gas in a predetermined direction at the lower end of the peeling drum 110. If there is one, it is not limited thereto.

Referring to FIG. 6 , the blowing member 140 may remove dust by flowing gas along an inclined direction of the lower end of the peeling drum 110 .

In another embodiment, the peanut peeler 100 may collect and remove dust generated by further providing a dust collecting member (not shown) at the end of the gas flow direction by the blowing member 140.

If the blowing member 140 is capable of implementing the above-described effect, its types include a member that guides the gas flow away from the blowing member 140 and a member that guides the gas flow closer to the blowing member 140. Not limited.

Through the following examples, the present invention is further detailed, but it is obvious that the present invention is not limited by the following examples.

Experimental example: performance evaluation

The performance of the peanut peeler manufactured according to Examples and Comparative Examples was evaluated.

The evaluation criteria were evaluation of molting efficiency and germination rate of seeds.

In the case of peeling efficiency, the quality of the experimental group was compared based on the performance of Example 2 for convenience of comparison, and the germination rate of seeds isolated from each separated case was evaluated.

The peeling efficiency of Comparative Example 2 was set to 100, and the quality of the remaining Examples and Comparative Examples was quantified.

The higher the threshing efficiency, the better the performance of the peeler, and the lower the damage rate, the lower the degree of damage to the target to be separated.

Referring to Table 2, while the Shore A hardness of the pressing member showed the highest level of peeling efficiency and seed germination rate in the range of 60 to 80, in the case of Comparative Example 1 using a metal pressing member, peeling efficiency decreased and seeds The germination rate was also significantly reduced. In the case of Comparative Example 2, the seed germination rate was slightly reduced due to its relatively high hardness, and in Comparative Example 3, the peeling efficiency was remarkably reduced due to the low hardness of the rubber.

In the case of Comparative Examples 4 to 6 in which the curved portion was not treated, the peeling efficiency and seed germination rate were significantly reduced.

The above results show that the peeling drum according to the present invention has excellent peeling efficiency, while minimizing damage to the object to be separated, which can be implemented by controlling the hardness and shape of the pressing member.
