Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method and apparatus for cleaning peas that have been harvested using a combine harvester or the like and are contaminated.

Conventional technology Conventional cleaning of peas uses a double-structured cleaning cylinder consisting of an outer cylinder made of a perforated plate and an inner cylinder whose surface is covered with fluff, and the gap between the outer cylinder and the inner cylinder is It was common practice to supply peas to the washing machine and wash the washing cylinder while rotating it.

Problems to be Solved by the Invention When cleaning using the above-mentioned conventional cleaning cylinder, there is a problem in that the fluff of the inner cylinder hits the beans against the outer cylinder, resulting in cracking of the beans and damage to the surface of the beans. It was hot. Furthermore, since the bean particles floating between the outer cylinder and the inner cylinder are cleaned with fluff, there is a problem in that the entire surface of the bean cannot be thoroughly cleaned without leaking. Furthermore, since these beans are packaged and shipped immediately after being washed, their surfaces remain slightly wet, causing problems such as the moisture content becoming higher than a predetermined value over time and the appearance of wrinkles on the epidermis. There was also the problem of deterioration in quality.

An object of the present invention is to solve such conventional problems and provide a method and apparatus for cleaning beans that can be cleaned and finished in a good condition.

Means for Solving the Problem As a means for achieving the above object, the first invention, a method for cleaning peas, has a surface with appropriate elasticity, as can be understood from FIG. 1 showing an embodiment thereof. Two cleaning belts 1 and 2 containing an appropriate amount of cleaning liquid are rotated at different speeds with the surfaces of the belts 1 and 2 parallel to each other and close to each other. W is pinched and rotated while running, and both cleaning belts 1,
This method is characterized in that the beans W discharged from step 2 are immediately dried and finished.

In addition, the second invention, a bean cleaning device, includes two cleaning belts 1 and 2 that have moderate elasticity on their surfaces, contain an appropriate amount of cleaning liquid, and rotate at different speeds. In order to compress the bean W between the surfaces of , 2 and make it run while rotating,
It is characterized in that the surfaces of the cleaning belts 1 and 2 are placed in parallel with each other in a stretched manner, and a drying device B for drying the bean grains W is provided on the bean discharge side of both cleaning belts 1 and 2.

Function When the beans W are supplied between the two cleaning belts 1 and 2, the beans W travel at a speed that is the sum of the speeds of the two cleaning belts 1 and 2 divided by 2. Since the surfaces of the cleaning belts 1 and 2 have elasticity, the particles W are wrapped in the surfaces of the cleaning belts 1 and 2 and are appropriately compressed, and furthermore, since the speeds of the cleaning belts 1 and 2 are different from each other, , it runs while rotating. As a result, the entire surface of the beans comes into contact with the appropriately moist surfaces of the cleaning belts 1 and 2, evenly and without leakage.
Cleaned and polished.

The beans W washed in this way are discharged from both washing belts 1 and 2 and passed through a drying device B.
Moisture adhering to the surface is immediately removed and finished.

Embodiments Examples of the present invention will be specifically described with reference to the drawings.

Reference numerals 1 and 2 are endless cleaning belts in which outer materials (surface materials) 1a and 2a made of slightly stiff sponge or nonwoven fabric are attached to stiff linings 1b and 2b. The outer materials 1a and 2a have moderate elasticity that wraps around the bean W,
It has a moderate liquid retention ability that absorbs a small amount of water or alcohol solution. And this one cleaning belt 2
On the surface (the surface of the outer fabric 2a), several endless groove-shaped bean running paths 3 extending in the belt direction are formed at appropriate intervals in the width direction of the belt. The bean running path 3 is a meandering path with a wide shallow bottom and a U-shaped cross section, and is wide enough to accommodate several bean grains W (about 5 to 7 mm in diameter) and deep enough to accommodate a little less than half a bean grain W. be.

The cleaning belts 1 and 2 have upper rolls 4 and 4 and lower rolls 5 and 5 arranged in two tiers in the horizontal direction, with their surfaces parallel to each other and close to each other (with an interval of approximately 1 to 2 mm).
They are lined up on racks. These cleaning belts 1 and 2 are
They are designed to be conducted so that they rotate at different speeds. Note that the rotation directions of the cleaning belts 1 and 2 do not necessarily have to be the same. Furthermore, the cleaning belts 1 and 2 may be formed horizontally as described above, but may also be vertically or inclined.

Reference numeral 6 denotes a bath liquid cleaning device for cleaning the surfaces of the cleaning belts 1 and 2, which includes a cleaning brush 7 that rotates in contact with the surface of each cleaning belt 1 and 2, and a cleaning liquid such as water or an aqueous alcohol solution applied to the brush 7. It consists of a liquid supply pipe 8 that injects liquid.

Reference numeral 9 denotes a liquid retention amount adjusting device for appropriately adjusting the amount of liquid retained (content of cleaning liquid) on the surfaces of the cleaning belts 1 and 2. Next to the bath liquid cleaning device 6, there is a squeezing roll 10.
It is set up in two stages.

In addition, the reference numeral 11 in the figure is a machine frame of the cleaning apparatus main body A, 12 is a supply hopper, and 13 is a discharge gutter.

B is the bean discharge side (discharge gutter 13) of the cleaning device main body A.
This drying device for bean grains W is attached to the side) and consists of a machine box 14 with a breathable soybean plate 15 slanted over the top surface and a hot air generator 16 installed in communication with the inside. The machine box 14 is shaped like a low and long immovable conveyor so that the beans W on the soybean plate 15 can be manually sorted. The drift bean board 15 is made of a permeable member such as a perforated board or a mesh board to blow up hot air, and has a guide piece 18 on its surface for forming a meandering path 17 for the beans W.
... are arranged, and a flow control plate 19 whose opening degree can be freely adjusted is installed downstream of the weir. The hot air generator 16 includes a burner and a blower.

Here, the cleaning action of peas based on Examples will be explained.

The washing belts 1 and 2 are supplied with beans W from the hopper 12.
When supplied between the two, the beans W enter the meandering path 3,
It is deeply wrapped in the surfaces of the cleaning belts 1 and 2 and runs while being appropriately compressed and rotated (see Fig. 5).
Moreover, the beans W meander through the meandering path 3 while rotating in various directions (see FIG. 4).
While the beans W stably travel on a predetermined course, their entire surfaces come into contact with the surfaces of the cleaning belts 1 and 2 evenly and without leakage, and are thoroughly cleaned and polished before being discharged from the discharge gutter 13. Ru.

In addition, the surfaces of the cleaning belts 1 and 2 that have been soiled by cleaning the peas W are brush-cleaned by being bathed in cleaning liquid by the bath liquid cleaning device 6, and the amount of the cleaning liquid absorbed at that time is transferred to the next liquid reservoir. The amount is adjusted appropriately by the amount adjusting device 9. Therefore, the beans W are always cleanly cleaned and polished by the surfaces of the cleaning belts 1 and 2, which are always clean and appropriately moist. The surface of this bean W is slightly wet.

The beans W discharged from the discharge gutter 13 in this manner are supplied onto the floating bean plate 15 of the drying device B, and naturally flow down while rolling on the floating bean plate 15 and being exposed to hot air from below. Moreover, beans W
While rotating in various directions on the meandering path 17,
Further, the flow rate and flow rate are appropriately adjusted by the flow control plate 19, and the flow takes a detour and flows down in a meandering manner. However, beans W
The entire surface is exposed to hot air evenly and without leakage,
The moisture adhering to the surface is immediately removed and the surface is finished. Then, the bean grains W flowing down on the flow bean board 15 are manually sorted by workers standing on both sides of the machine box 14, and moth-eaten grains, half-chipped grains, and immature grains are removed.

Effects of the Invention As described above, the present invention wraps the pea grains W between the surfaces of the two cleaning belts 1 and 2, presses them appropriately, and makes them run while rotating to clean them. Not only is there no chance of cracking the body of the bean W or damage to the surface of the bean W, but the entire surface of the bean W can be cleaned and polished evenly and without leaking.
It has the effect of finishing the product in good condition.

In addition, since the present invention immediately dries and finishes the washed peas W, the water adhering to the surface of the peas W is quickly removed, and the water content of the peas W remains at a predetermined level as in the conventional method. higher than the value,
Wrinkles do not occur on the epidermis of the pea grains W, which has the effect of stabilizing the quality.

In addition, if the machine box 14 is formed in the shape of a low and long immovable conveyor as in this embodiment, a synergistic effect is produced in which the beans W on the floating bean plate 15 can be manually sorted.
