All-in-one coarse crusher for grain}

The present invention includes a crushing unit that crushes grains with husks, separates the husks from the grains, and discharges them; a peeling unit that selects and discharges the grains and grains discharged from the crushing unit into a first discharge unit and a second discharge unit, respectively; A coarse grinding unit connected in communication with the first discharge part of the peeling unit and coarsely crushing grains discharged from the first discharge unit, wherein grains with husks are sequentially divided into the crushing unit, the peeling unit, and the coarse grinding unit. It relates to an integrated coarse grinding device for grains, characterized in that it is composed of coarse grinding material from which the husk is removed during processing.

Grains refer to the fruits of agricultural crops used for food and include rice, barley, beans, millet, millet, sorghum, wheat, and corn. The main component of grain is starch, and not only does it have a light taste, but it also has a low moisture content, making it easy to handle and store for a long time. It is also easy to distribute, so it has been widely used since ancient times as the most important food among all foods. Therefore, wheat is mainly used as a staple food in many Western countries and Australia, rice in Southeast Asia and the Far East, and corn in Latin America.

These grains are processed into powder form, distributed and stored to manufacture other foods (bread, beverages, etc.). In order to process the above-mentioned grains into powder form, a grain grinder has been used in the past. The grain grinder includes a rotary grinding blade that rotates at high speed by a motor while the grains input through the upper input hopper are transferred to the lower grinding unit. It is finely pulverized and turned into powder by repeating the process of colliding and scattering on a fixed fixed grinding blade. The pulverized powder is passed through a screening net consisting of a mesh sieve installed in the grinding unit, and only powder of a certain particle size is passed through the lower part. Discharge occurs through the outlet.

However, when using such a grain grinder, there was a problem that the quality of the powder deteriorated because the grain husks were mixed with the powder. Therefore, before putting the grains into the grinder, the work of removing the grain husks in a separate dehuller had to be done first. .

In addition, when it is desired to coarsely grind grains, a crusher for crushing the grains, a dehuller for removing the husks of grains, and a coarse grinder for coarsely crushing the grains from which the husks have been removed must be separately provided as shown in Figure 1. Device configuration A lot of manpower is invested in each process, and in the process of moving the raw materials that have been completed from one device to the equipment for the subsequent process, loss of raw materials, contamination of foreign substances or pests, etc. occurs, leading to a decrease in the quality of the powder. It continued.
