Description

Technical Field

[0001] This utility model relates to the field of rice bran meal production technology, specifically to a raw material crushing device for rice bran meal production. Background Technology

[0002] Rice bran meal is made from rice bran, specifically a byproduct of rice processing. Rice bran is a mixture of the bran, germ, and broken rice that is removed during the whitening process of brown rice, and it is rich in nutrients such as protein, oil, vitamins, and minerals.

[0003] For example, a raw material crushing device with announcement number "CN219129399U" uses a cam and a screening plate in combination. When the crushing rollers crush the raw material, one of the crushing rollers drives the drive pulley to rotate. The drive pulley drives the driven pulley to rotate via a belt. The driven pulley drives the rotating rod to rotate, which in turn drives the cam to rotate. During the rotation of the cam, it pushes the screening plate upward and compresses the spring. When the cam disengages from the screening plate, the screening plate returns to its original position due to the force of the spring. This cycle repeats, causing the screening plate to vibrate and screen the crushed raw material, thus enabling the crushing device to perform a screening function without the need for transferring and screening the crushed material, thereby improving the working efficiency of the crushing device. However, with this raw material crushing device, if too much raw material is poured in for crushing, a large amount of raw material entering the crushing rollers can easily lead to uneven crushing, with some particles being too large and others too small, failing to meet the usage requirements. At the same time, crushing the raw material through the primary crushing rollers can easily result in incomplete crushing, failing to reach the specified size. Therefore, it is necessary for workers to manually collect the raw material for secondary crushing, which consumes the workers' physical strength and increases labor costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the raw material crushing equipment. In this equipment, all raw materials are poured into the box at once for crushing. The large amount of raw materials entering the crushing roller can easily lead to uneven crushing. At the same time, crushing the raw materials through the crushing roller once can easily lead to incomplete crushing and failure to reach the specified size. Therefore, it is necessary for the staff to manually collect the raw materials and crush them again, which consumes the staff's physical strength and increases the labor force. Therefore, a raw material crushing device for rice bran meal production is proposed.
