Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bean cleaning device for cleaning soiled bean grains that have been harvested by a combine harvester or the like.

Conventional technology In conventional cleaning of peas, 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 is used. It was common practice to feed beans into the gap between the washing cylinders 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 bean cleaning device that cleans and finishes beans in a good condition.

Means for Explaining the Problems As a means for achieving the above object, the pea washing device of the present invention has two peas having appropriate elasticity and water retention on their surfaces and rotating at different speeds. The cleaning belts 1 and 2 are stretched parallel to each other with their surfaces facing each other in parallel, so that the cleaning belts 1 and 2 run while rotating while pinching the peas W between the surfaces of the belts 1 and 2. , 2 are associated with a belt cleaning device 6 at an appropriate position above their rotational travel, and a bean drying device B equipped with a hot air generator 16 is installed on the bean discharge side of the cleaning belts 1 and 2. Furthermore, the belt cleaning device 6 includes:
The water supply pipe 21 is characterized by being connected to the hot air generating device 16 of the drying device B at an appropriate intermediate portion so that the water supply pipe 21 can be heated by the pea drying device B.

Function The bean W that supplies the bean W between the two cleaning belts 1 and 2 runs 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 pinched, 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 surfaces of the cleaning belts 1 and 2 evenly and without leakage, and is thoroughly cleaned and polished.

Further, the surfaces of the cleaning belts 1 and 2 are themselves cleaned by the belt cleaning device 6, and at the same time, they retain cleaning water for cleaning the beans W. As a result, the surfaces of the cleaning belts 1 and 2 are constantly washed and cleansed, and the peas W are constantly cleaned, and the surfaces of the cleaning belts 1 and 2 always retain an appropriate amount of cleaning water.
Always cleanly remove dirt from pea grains W. In particular, since the washing water of the belt washing device 6 is heated by the bean drying device B and becomes hot water, the washing water of the washing belts 1 and 2 is
To make it easier to remove dirt from pea grains W and to make the cleaning action more effective.

The beans W thus washed are discharged from the cleaning belts 1 and 2 and passed through the beans drying device B, where the water adhering to the surface of the beans is immediately removed and finished. In particular, since the water adhering to the surface of the beans W is warm water as described above, its evaporation is accelerated, making the drying effect more effective.

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

A indicates the main body of the cleaning device. 1 and 2 are endless cleaning belts in which a slightly stiff outer material (surface material) made of sponge or nonwoven fabric is attached to a stiff lining material. The outer material has appropriate elasticity to wrap around the bean W and adequate liquid retention ability to absorb a small amount of washing water.

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. Further, the cleaning belts 1 and 2 may be formed horizontally as described above, but may also be vertically or inclined.

Reference numeral 21 denotes a water supply pipe for supplying washing water to the belt washing device 6. One end is connected to the washing pipe 8 of the belt washing device 6, the other end is connected to the water faucet 22, and the intermediate portion is connected to the bean drying device B as appropriate. An associated arrangement is made in the machine box 14 of the drying device B to be heated. The water supply pipe 21 has a meandering structure to increase its heat receiving area so that it is exposed to hot air from the hot air generator 16. In addition to the above embodiments, the heating structure of the water supply pipe 21 may include a structure in which the water supply pipe 21 is wound around a furnace 19 (see Fig. 2), or a structure in which the water supply pipe 21 is connected to a boiler-shaped furnace 19. structure (see FIG. 3). The code 23 in the figure is the water supply pipe 2
This is a flow control valve for the wash water flowing inside the 1.

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 cleaning belts 1 and 2, the peas W are wrapped around the surfaces of the cleaning belts 1 and 2, are appropriately clamped, run while rotating, are thoroughly cleaned and polished, and are sent to the discharge tub 1.
It is discharged from 3.

Further, the washing water supplied from the water faucet 22 to the washing pipe 8 of the belt washing device 6 is exposed to hot air from the pea drying device B on the way and becomes hot water. Therefore, the cleaning belt 1, which is dirty after cleaning the grains W,
The surface of the belt 2 is well brush-washed by being bathed in hot washing water by the belt washing device 6, and the hot washing water absorbed at that time is adjusted to an appropriate amount by the next water retention amount adjusting device 9. Therefore, the peas W are always cleanly cleaned and polished by the surfaces of the cleaning belts 1 and 2, which are always clean and have appropriate temperature and humidity. The surface of this bean W is slightly wet.

The beans W discharged from the discharge tub 13 in this manner are supplied onto the floating bean plate 15 of the bean drying device B, and are naturally flowed down while rolling on the floating bean plate 15 and being exposed to hot air from below. The cleaning hot water adhering to the surface is immediately removed and finished. Then, the bean grain W flowing down on the flowing bean plate 15
The grains 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 peas W between the surfaces of the two cleaning belts 1 and 2, applies appropriate pressure to them, and runs them 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.

Further, the present invention provides a belt cleaning device 6,
Since the cleaning belts 1 and 2 are always cleaned and the cleaning belts 1 and 2 are always kept with cleaning water, it is possible to continue cleaning and polishing the peas W even more neatly over a long period of time.

Furthermore, in the present invention, the washed peas W are immediately dried and finished, so that the water adhering to the surface of the peas W is quickly removed, and the moisture content of the peas W is reduced as in the conventional method. This prevents the temperature from becoming higher than a predetermined value and from causing wrinkles on the outer skin of the beans W, resulting in the effect of stabilizing the quality.

In particular, in the present invention, since the washing water supplied to the belt washing device 6 is heated by the bean drying device B to make it hot water, it is possible to easily remove dirt from the washing belts 1 and 2 and the bean W. This has the excellent effect of making it easier to evaporate the washing warm water adhering to the surface of the washed peas W, thereby further promoting the cleaning action and drying action of the peas W. Further, the present invention has an economical effect since washing water can be heated without requiring a separate heating device.
