Description

[Detailed description of the invention] Industrial application field This invention efficiently produces soybeans, which are used as raw materials for manufacturing tofu, miso, natto, etc., and legumes, such as azuki beans, kidney beans, and cowpeas, which are used as raw materials for manufacturing bean paste, sweet natto, etc. The present invention relates to a cleaning device.

Conventional technology Legumes are used as raw materials for manufacturing various foods.
Prior to processing, it is necessary to remove sand, mud, soil bacteria, and debris that adhere to the surface. Up until now, the method of washing such beans has been to simply use a container equipped with a stirrer, place the beans in the container, pour running water over the container, and stir the beans while the water overflows.

However, since such a method is batch-based, the amount that can be processed is limited, it is inefficient, and it cannot be incorporated into a continuous process.

Problems to be Solved by the Invention This invention was made for the purpose of providing a continuous washing device that can efficiently wash a large amount of beans.

Means to Solve the Problems As a result of extensive research to develop a device for continuously washing pulses, the inventor of the present invention has discovered that a screw feeder with spiral blades made of a perforated plate is used to continuously wash pulses. Efficient cleaning is carried out by pushing the beans in one direction and cleaning the surface of the beans by bringing them into contact with a flowing water stream that efficiently flows through the holes of the perforated plate in the opposite direction to this pushing direction. We discovered this and came up with this idea based on this knowledge.

That is, this invention has a screw feeder 7 in which a spiral blade 6 is formed of a perforated plate inside a horizontal cylindrical casing 1 which has both ends facing upward and one of which is a curved pipe. A pulse outlet 1 is installed inside the casing 1 and has a water inlet 11 at an appropriate position on the circumference of one of the curved pipes at both ends of the casing 1.
0. To provide a bean washing device in which the other side is configured as a bean input port 8 having an overflow port 9 at a suitable location.

Embodiment Next, an embodiment of this invention will be explained with reference to the drawings. In FIG. 1, 1 is a casing, the middle part is horizontally cylindrical, and both ends are one side (the left end in the figure).
One is a straight pipe section 2 that opens upward, and the other is a curved pipe section 3 that opens upward.

Inside this casing 1 is a screw feeder 7 consisting of a rotating shaft 5 whose one end is connected to a drive mechanism 4 outside the casing, and a spiral blade 6 fixed to this rotating shaft. It is made of a perforated plate.

Next, the straight pipe portion 2 of both ends of the casing 1 is
The upper end opening is used as the legume inlet 8, and
As is clear from FIG. 2, the overflow port 9 is formed by providing a small pipe in a direction perpendicular to the main body of the casing 1, and the bent pipe portion 3 opens at the upper end as a legume discharge port 10, and a small pipe is provided slightly below it. water inlet 11
is attached.

Effects This device has the above-mentioned structure, and the beans to be washed are supplied to the beans input port 8, pushed out to the right in FIG. 1 through the screw feeder 7, and overflowed from the beans discharge port 10. By continuously injecting a constant amount of water from the water inlet 11 and letting it flow out from the overflow port 9, the cleaning water is forced through the screw feeder through the holes in the helical blades of the screw feeder. Since the beans are in countercurrent contact with the legumes, the legumes are affected by mutual friction caused by the screw feeder and
The constantly fresh water flow that faces the direction of movement of the beans and also flows through the holes in the spiral blades enables efficient cleaning, and the beans can be taken out smoothly along the curved surface of the curved pipe. The process can be carried out easily by being transferred upwards, large quantities and continuous processing can be performed, and the entire apparatus can be made compact as shown in the figure, which is very convenient for industrial implementation.
