Bran discharging mechanism and milling equipment

Abstract

The invention provides a bran discharging mechanism and milling equipment, and belongs to the field of grain processing machinery, and the bran discharging mechanism comprises a separation body arranged at the bottom of a discharge port and used for receiving milled grains and bran coats; the bran outlet pipe is arranged on the side face of the separation body, communicates with the separation body and is used for collecting bran; the negative pressure generator is arranged in the bran outlet pipe and used for generating negative pressure to generate suction force on the bran in the separation body, so that the bran enters the bran outlet pipe, a plurality of flow guide plates are arranged in the separation body and are sequentially arranged on the inner walls of the two sides of the separation body in a staggered mode in the length direction of the separation body, and the flow guide plates are arranged on the inner walls of the two sides of the separation body. Grain flows out from the bottom of the separation body after sequentially passing through the flow guide plates, each flow guide plate obliquely extends from the corresponding inner wall to the direction away from the discharge port, a bran outlet is formed in the side, away from the discharge port, of the flow guide plate farthest from the discharge port on the inner wall of the separation body, and the bran outlet pipe is fixedly connected to the bran outlet.

Description

technical field [0001] The invention belongs to the field of grain processing machinery, and particularly relates to a bran discharging mechanism and a grinding device. Background technique [0002] Milling equipment is a type of equipment used to grind large particulate matter into small particulate matter. For example, a rice mill is a relatively common milling equipment, and its function is to peel brown rice to form polished rice. [0003] Conventional rice mills usually use the extrusion principle, which can easily lead to broken rice grains. In order to reduce the phenomenon of broken rice grains, there are some equipments in the prior art that use abrasive belt grinding for peeling. The grinding equipment using the abrasive belt includes a frame, a feeding device, a discharging device, a main drum, an abrasive belt sleeved on the main drum, and a whitening chamber surrounding the main drum. After the brown rice is milled, polished rice and grain bran will be produc...

AI Technical Summary

Problems solved by technology

The bran discharge room is set under the whitening room, and the bran discharge fan is set at the bran outlet of the bran discharge room. The rice bran in the whitening room is discharged from the whitening room under the action of the blowing wind net, and finally enters the bran outlet from the bran outlet. The pipe is sucked away, but the efficiency of the existing device for discharging the bran hole is low, the bran discharge chamber is not completely discharged, and it is troublesome to replace the collection device
