Rice and bran separation type rice milling machine

Abstract

The invention belongs to the technical field of rice milling equipment and relates to a separation type rice milling machine. The separation type rice milling machine comprises a case, a spindle, a bran sieving device, a bran collection chamber, a driving motor and a rice and bran separator; a whitening chamber is formed between the spindle and the bran sieving device; the bran collection chamberused for bran outlet is formed in the bottom of the whitening chamber; an output shaft of the driving motor is connected with the spindle through a belt; an emery roller for milling rice is arranged on the upper portion of the spindle; a spiral propeller is arranged in the position, on the lower portion of the whitening chamber, of the spindle; a feeding inlet for feeding of rice in husks is formed in the lower portion of the case; a discharging outlet for rice outlet is formed in the upper portion of the case and provided with a discharging pipe; the discharging pipe is connected with one endof the rice and bran separator, and the other end of the rice and bran separator is fixedly connected with a bran suction pipe; a negative pressure fan is arranged at one end of the bran suction pipe; a rice collection chamber is connected to the lower end of the rice and bran separator. The separation type rice milling machine has the uniform whitening effect, and rice grains are not piled at the bottom of the rice milling machine and can be subjected to secondary bran removing.

Description

technical field [0001] The invention belongs to the technical field of rice milling equipment, and in particular relates to a rice bran separation type rice miller. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. After the husking process, the brown rice includes the epidermis and the rice body, and then enters the rice milling process, where the brown rice is milled and rubbed with a rice mill to separate the brown rice epidermis from the rice body, and then the rice is brushed, bran removed, De-crushing, drying rice and other treatments to get the rice of the required grade. Among them, rice milling is one of the most important processes. The traditional horizontal rice mill is inconvenient to use. The rice grains are affected by their own gravity and suction under negative pressure. When the rice grains flow in the whitening room, a large amount of them will accumulate in the lower ...

Problems solved by technology

But the reality is that a small amount of bran powder will be discharged from the outlet of the whitening room together with the rice grains, and mixed and packed, resulting in poor quality of white rice
