Technical Field

The utility model belongs to the technical field of the rice dust collector, concretely relates to rice dust pelletizing system.

Background

The processing process flow of the practical application of the rice processing enterprise at present is as follows: raw grain → suction grain → weighing → air separation → scraper conveying → warehousing → electromagnetic receiving → conveying → primary cleaning → impurity cleaning → primary stone removal → dust separation → magnetic separation → husking → paddy separation → secondary stone removal → magnetic separation → coarse storage case → first rice milling → second rice milling → white rice grading → length grading → white rice stone removal → rice storage case → polishing → air screening → color selection → material storage → weighing and packaging → finished product warehousing.

In the raw grain treatment process, the raw grain is usually subjected to primary cleaning, stone removal and other treatments, so as to achieve the purposes of removing impurities in the rice and the like. Meanwhile, the rice belongs to granular articles, and a large amount of dust is generated in the impurity removing process of the rice. If the dust removal measures are improper, a large amount of dust is easy to escape.

Similarly, dust such as bran powder can be generated in the processes of rice milling and polishing, and environmental pollution can be caused if the dust removal facility is unreasonable.

Present rice dust pelletizing system only once removes dust or removes dust not thoroughly, causes the low or long time consuming that removes dust quality easily, like CN201921375003.8 discloses a rice dust collector, including supporting the base, the top fixedly connected with rice dust removal storehouse of support base, the top fixedly connected with motor case in rice dust removal storehouse, the bottom fixedly connected with motor of motor case, the vertical gear of one end fixedly connected with of motor, just the inner chamber top threaded connection of motor case has the dwang, transverse gear has been cup jointed to the one end of dwang, transverse gear joint is in the one end of vertical gear the other end of dwang runs through rice dust removal storehouse and extends to inside, just the middle-end of dwang has cup jointed the carousel, the one end fixedly connected with stirring rod of carousel, just the left end fixedly connected with conveying pipeline in rice dust removal storehouse.
