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 tank 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 peas are hit by the fluff of the inner cylinder against the guests, causing the peas to crack or the surface of the peas to be damaged. there were. Also,
Since the peas floating between the outer cylinder and the inner cylinder are cleaned with fluff, there is also a problem in that the entire surface of the peas cannot be thoroughly cleaned without leaking. Furthermore, because these beans are packed and shipped immediately after being washed, their surfaces remain slightly wet, causing problems such as the moisture content becoming higher than a specified 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-mentioned object, the first invention, a method for cleaning peas, uses a method that imparts appropriate elasticity to the surface, as can be understood from FIG. 1 showing an embodiment thereof. Two cleaning belts (1, 2) containing an amount of 'S' of cleaning liquid are rotated at different speeds with the surfaces of the belts (1, 2) facing each other in parallel with each other, The pea grains (W) are pinched between their surfaces and run while rotating,
This method is characterized in that the beans (W) discharged from both washing belts (1, 2) are immediately dried and finished.

In addition, the second invention, a device for washing peas, comprises two washing belts (1, 2) that have moderate elasticity on their surfaces, contain an appropriate amount of washing liquid, and rotate at different speeds. In order to pinch the grains (W) between the surfaces of the belts (1, 2) and make them run while rotating, the surfaces of the belts (1, 2) are stretched parallel to each other and are placed close to each other, facing each other, and both cleaning belts (
This apparatus is characterized in that a bean (W) drying device (B) is provided on the bean discharge side of 1 and 2).

Function When beans (W) are fed between the two cleaning belts (1, 2), the beans (W) run at a speed that is the sum of the speeds of the two cleaning belts (1, 2) divided by 2. . Since the surface of the cleaning belt (1゜2) has elasticity, this bean (W) is wrapped in the surface of the cleaning belt (1゜2) and is appropriately pinched, and moreover, Since the speeds of 2) are different from each other, they run while rotating. As a result,
Use a cleaning belt (1, 2
) is cleaned and polished by contacting the surface evenly and without leakage.

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

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

A indicates the main body of the cleaning device. l, 2 is j! ! Using the cleaning belt at the end, remove the outer material (surface material) la, 2a made of slightly stiff sponge or non-woven fabric, etc., and the stiff lining material 1b, 2b.
The outer fabrics la and 2a that are attached to the surface have appropriate elasticity to wrap around the bean W, and appropriate liquid-retaining properties to absorb a small amount of water or an aqueous alcohol solution. On the surface of one of the cleaning belts 2 (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. This bean run #3
is a meandering path with a wide, shallow bottom, and a U-shaped cross section, which is wide enough to accommodate several peas W (about 5 to 71III in diameter) and deep enough to fit a little less than half a pea W.

The cleaning belts 1 and 2 are stretched over upper rolls 4 and lower rolls 5 and 6, which are arranged in two horizontal stages, with their surfaces parallel to each other and close to each other (at an interval of approximately 1 to 2 m+*). They are installed side by side. The cleaning belts 1.2 are arranged to run in rotation at mutually different speeds. Note that the rotational directions of the cleaning belts 1 and 2 do not necessarily have to be the same, and the type of the cleaning belt 1.2 may be formed not only horizontally as described above but also vertically or inclinedly. In some cases.

Reference numeral 6 denotes a bath liquid cleaning device for cleaning the surfaces of the cleaning belts 1 and 20, which includes a cleaning brush 7 that rotates in contact with the surface of each cleaning belt 1.2, and a cleaning liquid such as water or an aqueous alcohol solution applied to the brush 7. It consists of a liquid supply vibrator 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 surface of the cleaning belt 1.2, and a squeezing roll 10 is provided in two stages next to the bath liquid cleaning device 6. It becomes.

In addition, the code|symbol 11 in a figure is a machine frame of the washing|cleaning apparatus main body A, l2 is a supply hopper, and 13 is a discharge gutter.

B is a drying device for bean grains W attached to the bean discharge side (discharge gutter 13 side) to the main body of the washing device, and a permeable drift plate 15 is installed on the top surface.
It consists of a machine box 14 which is installed at an angle and has a hot air generator 16 installed in communication with it. The machine box 14 is shaped like an elongated 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 in order to blow up hot air, and the meandering path 1 of the bean grains W is formed on its surface.
A guide piece 18 for forming the flow rate 7 is disposed, and a flow control plate 19 whose opening degree can be freely adjusted is provided downstream of the guide piece 18. The hot air generator 16 includes a burner and a blower.

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

When the beans W are fed between the cleaning belts 1 and 2 from the supply hopper 12, the beans W enter the meandering path 3 and move between the cleaning belts 1 and 2.
It is deeply wrapped in the surface of 2 and runs while rotating under moderate pressure (see Fig. 5).

Moreover, the beans W meander through the meandering path 3 while rotating in various directions (see FIG. 4).

While the peas 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.
It is discharged from 3.

In addition, the surface of the cleaning belt 1.2, which has been soiled by cleaning the peas W, is brush-cleaned by being bathed in cleaning liquid by the bath liquid cleaning device 6. The adjustment device 9 provides appropriate adjustment. However,
Bean grain W is a cleaning belt 1 that is always clean and appropriately moist.
．． 2 surface keeps it clean and polished. 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, the peas W rotate in various directions on the meandering path 17, and the flow rate and flow rate are appropriately adjusted by the flow control plate 19 as they detour and meander down. As a result, the whole surface of the pea grain W is exposed to the hot air uniformly and without leakage, and the water adhering to the surface is immediately removed and finished. Then, the bean grains W flowing down on the drift bean plate 15 are manually sorted by workers standing on both sides of the machine box 14, and moth-eaten grains, half-hole grains, and immature grains are removed.

Effects of the Invention As mentioned above, the present invention wraps the peas (W) between the surfaces of the two cleaning belts (1, 2), presses them appropriately, and runs them while rotating to clean them. Unlike conventional methods, there is no cracking of 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 uniformly and without leaking ) 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 peas (W) can be finished as they were before.
) will not become higher than a predetermined value, and the epidermis of the beans (W) will not wrinkle or bend, resulting in the effect of stabilizing the quality.

In addition, if the machine box 14 is formed in the shape of an elongated immovable conveyor as in this embodiment, a synergistic effect is produced in which the beans W on the floating bean plate 16 can be manually sorted.
