Screening and spraying device for feed processing based on Bernoulli principle

Abstract

The invention relates to the technical field of feed processing and discloses a screening and spraying device for feed processing based on the Bernoulli principle. The device comprises a base, whereina first fan blade is arranged at an upper part of the first rotating shaft, an upper part of the integral shell is connected with a screen, the upper side of an inclined plate is provided with a ventilation plate, a lower end of the first rotating shaft is fixedly connected with a centrifugal device, an upper part of the centrifugal device is surrounded by a third through hole, a lower end of thecentrifugal device is connected with a second rotating shaft, a lower end of the second rotating shaft is provided with a second leaf, the first rotating shaft drives the centrifugal device to rotate, the large particle feed enters into the centrifugal device through the first rotating shaft for centrifugal processing and then is thrown out through the third through hole, a second rotating shaftis driven by the centrifugal device to rotate, and the second rotating shaft drives the spraying liquid on an inner part of an outer side of a conical plate through a second blade to be included in the spraying liquid collection box. The device is advantaged in that problems of waste of feed spray liquid and excessive grease of feed in a feed screening and spraying device in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a screening and spraying device for feed processing based on the Bernoulli principle. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or pasture. Feed processing refers to the feed production and processing activities applicable to farms and farmers raising livestock and poultry, including the production of pet food. After the feed is processed into granules, it needs to be classified, and the unqualified feed granules are sieved through a sieve; Feed granules are sprayed with animal and vegetable oil, thereby improving the appearance quality of the feed and the quality of the finished product. [0003] However, the existing feed screening is prone to dust, and the dust disperses into the air, which affects the processing envir...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a screening and spraying device for feed processing based on Bernoulli's principle, which has the advantages of ensuring the quality of the feed, avoiding the waste of spraying liquid and preventing excessive grease on the feed, and solves the problem of The existing feed screening and spraying device can not guarantee the quality of the feed, the waste of feed spraying liquid is too much and the problem of too much oil on the feed
