Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method for removing surface deposits from grains such as rice, wheat, and red beans, and other granular materials.

Conventionally, as a method for cleaning this type of particulate matter, a method is known in which surface deposits are removed by sequentially rubbing the particulate matter between the facing surfaces of rotating belts arranged in multiple stages facing each other in a horizontal state. In most of these conventional methods, the particulate matter is rubbed while rotating in the same direction and at the same speed, and although it can be expected to remove a certain amount of surface deposits, it is not possible to remove the surface deposits almost completely. Since it cannot be removed to the extent that it can be removed and furthermore, the treatment requires a long time, improvements and improvements have been desired.

Therefore, the present invention has been developed in view of the above points, and it is an object of the present invention to attach the surface of the granular material by rubbing the granular material in a rubbing manner while frequently changing the direction and speed of rotation of the granular material during the cleaning process. It is an object of the present invention to provide a method for cleaning particulate matter that can efficiently and almost completely remove kimono.
Specifically, in a method for cleaning particulate matter, the cleaning belt is wound around at least a pair of basic roller belts which are positioned facing each other in an inclined state, and the particulate matter is inserted and rubbed between the opposing surfaces of these cleaning belts. The opposing parts of the cleaning belts are moved in the same direction and both cleaning belts are moved intermittently or at variable speeds, and the particulate matter inserted between the opposing surfaces of the cleaning belts is rotated in forward and reverse directions and at variable speeds. It is an object of the present invention to provide a method for cleaning particulate matter characterized by frequent rubbing.

The details will be explained below with reference to the illustrated example. The figure shows a schematic diagram of a particulate matter cleaning device, and in the figure, 1a and 1b are a pair of units 1a and 1b positioned facing each other in an inclined state toward the base frame 2. This pair of basic roller belts 1a and 1b are basic roller belts.
A cleaning belt 3a, 3b is wound around each of the cleaning belts 3a, 3b, and a slight gap 5 as a cleaning processing section is formed between the opposing surfaces 4a, 4b of both cleaning belts 3a, 3b. Further, granular materials 7, such as rice, wheat, red beans, etc., are input and can be taken out from the lower hopper 8.

The two basic roller belts 1a, 1b connected to a power source (not shown) are used as driving sources to rotate the cleaning belts 3a, 3b, which are wound around them, at different speeds and in symmetrical directions (in the illustrated example, the cleaning belts 3a clockwise (arrow A
Also, the cleaning belt 3b is rotated in the counterclockwise direction (in the direction of arrow B) to move the opposing parts of the cleaning belts 3a and 3b in the same direction (in the example shown, from the top to the bottom), and in addition, the The cleaning belt 3
Both a and 3b are rotated at variable speeds intermittently or at predetermined intervals. At this time, the timings of the intermittent state and variable speed state of both cleaning belts 3a and 3b are slightly shifted so that when one is moving, the other is stopped. The intermittent or variable speed operation of both cleaning belts is appropriately set depending on the opposing lengths of the tarnishing belts, and is performed frequently (for example, several times per second).

In addition, in the above and below, "intermittent" means something that repeats a stopped state and a rotating state, and includes both intermittent movement that repeats this at regular intervals and movement that repeats irregularly, and "variable speed" This refers to a state in which the speed repeatedly increases or decreases periodically or irregularly in the rotating state.

When the particulate material 7 is thrown into the gap 5 between the cleaning belts 3a and 3b as a cleaning processing section from the upper hopper 6, the opposing parts of the cleaning belts 3a and 3b move at different speeds in the same direction (in the illustrated example, upward These cleaning belts 3a and 3b rotate and rub the particulate matter 7 within the gap 5 by moving the particulate matter 7 intermittently or at variable speeds, and also frequently and forcibly move the particulate matter 7 forward and backward. While rotating and changing the rotational speed, all surfaces of the granular material 7 are evenly rubbed and sent to the lower hopper 8.

As explained above, when using the method for cleaning particulate matter according to the present invention, the cleaning belts are wound around at least a pair of basic roller belts that are positioned opposite each other in an inclined state, and the opposing parts of the cleaning belts are connected to each other via the basic roller belts. in the same direction and both cleaning belts are moved intermittently or at variable speeds, and the particulate matter inserted between the opposing surfaces of the cleaning belts is frequently rubbed while rotating in forward and reverse directions and at variable speeds. Therefore, by frequently and forcibly changing the rotating direction and rotation speed of the granular material, the granular material is rubbed and rubbed, so that the cleaning belt can remove the surface deposits of the granular material in a short time and efficiently. Moreover, it is possible to completely rub all sides of the granular material evenly, and by moving both cleaning belts intermittently or at variable speeds, it is easy to fine-tune the cleaning process, and it is possible to rotate in many directions in a short period of time. Since it is possible to apply a change in the rotational speed to the granular material, it has great effects such as further improving the cleaning processing ability.
