Compact type high-efficiency combined rice milling machine

Abstract

The invention relates to a compact type high-efficiency combined rice milling machine comprising a machine body and a motor. The top of the machine body of the compact type high-efficiency combined rice milling machine is provided with a rice hulling machine head and a fan, the top of the rice hulling machine head is provided with a feed hopper, a bran separator and a rice milling machine are arranged in the machine body from top to bottom, an air inlet at the bottom of the fan is connected with a bran outlet at the top of the bran separator, an unpolished rice outlet at the bottom of the bran separator is positioned above the feed hopper of the rice milling machine, and the bottom of the rice milling machine is provided with a fine bran hopper; according to the compact type high-efficiency combined rice milling machine, the functions of rice hulling, rice milling and fine processing are integrated; and the compact type high-efficiency combined rice milling machine has the characteristics of compact structure, small size, little energy consumption, short processing procedure, low processing cost, convenient operation and the like. According to the compact type high-efficiency combined rice milling machine, a rice milling chamber has a simple structure, a strip-shaped rice knife of a fixed screen mesh and a rice milling roller are matched with high efficiency, and the quickness and the cleanness of rice milling are ensured. A rice output regulating device can be used for regulating the magnitude of the frictional force of the rice milling of unpolished rice, and the rice output rate is high. By applying the device, the inherent defect of a traditional rice milling machine can be overcome, and the condition of obtaining rice with low broken rice rate and bright and integral rice grains becomes a normal state.

Description

technical field [0001] The invention relates to a combined rice mill for grain processing, in particular to a compact and high-efficiency combined rice mill. Background technique [0002] To grind the grain into rice, you need to use a rice huller and a rice mill. Commonly used huskers include rubber roller huskers and sand disc huskers. The main components of the rubber roller husker are a pair of parallel rubber rollers. The two rollers rotate in opposite directions and have different peripheral speeds. When the grains pass through the rolling distance between the two rollers, they are shelled due to tearing and rubbing. Adjusting the rolling distance between the two rubber rollers or sand discs of the husker can obtain a suitable husking efficiency and reduce the damage of rice grains. After the rice has been hulled, there are still about 20% of the unhulled rice, so the materials after hulling (the mixture of brown rice, rice and chaff) need to be separated by winnowin...
