Description

Technical Field

[0001] This utility model relates to the field of rice technology, specifically a desiccant device for rice processing. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy grains through processes such as cleaning, hulling, milling, and finishing. Rice contains nearly 64% of the nutrients found in paddy rice and more than 90% of the nutrients needed by the human body. It can be divided into three types: indica rice, japonica rice, and glutinous rice. There are many ways to eat rice. People usually use methods such as steaming or braising to make cooked rice, or cooking rice into porridge. The basic chemical principle of these cooking methods is the gelatinization reaction that occurs when rice and water are heated together. It is through this gelatinization reaction that rice becomes a food that people can eat directly. After paddy rice is processed, due to storage and transportation, the rice grains rub against each other, producing small pieces of bran. These small pieces of bran mixed in with the rice affect its taste. Usually, equipment is used to screen and separate these small pieces of bran.

[0003] Existing screening equipment includes air separation equipment. Air separation utilizes the difference in suspension velocity between materials and impurities to remove light impurities and dust by means of wind power. Existing air separation equipment usually uses a sieve plate to scatter rice during air separation, and uses a fan to separate the lighter scraps from the rice. Because the amount of material is relatively large when scattering, the rice and scraps cannot be evenly dispersed and suspended, resulting in poor screening effect.

[0004] Therefore, those skilled in the art have provided a desiccant device for rice processing to solve the problems mentioned in the background art. Utility Model Content
