Fish feed drying and spraying device

Abstract

The invention relates to a fish feed drying and spraying device. The device can be used for simultaneously carrying out drying and spraying processes of a fish feed; meanwhile, the device adopts a rotary feeding mode to carry out feeding, so that falling time and dispersity of the fish feed in a drying and spraying bin are improved and the fish feed is more completely dried and sprayed; moreover, the device uses an ultrasonic vibrating spray nozzle as a spray nozzle for spraying grease and the grease can be dispersed into small particles in a vibrating manner by the ultrasonic vibrating spray nozzle, so that the fish feed is guaranteed to be more completely sprayed and the sprayed grease is saved; and in addition, the device is provided with a cooling tank and an oil-water separation device, so that the grease in residual gas of the dried and sprayed fish feed can be recycled.

Description

technical field [0001] The invention relates to a feed processing device, in particular to a fish feed drying and spraying device, which belongs to the field of mechanical design. Background technique [0002] The processing of fish feed requires batching, stirring, tempering, granulation, drying and other processes. In order to make the fish feed not easy to be wetted by water in the water and cause waste, it is necessary to spray waterproof coating on the outside of the processed fish feed. oily substance. [0003] Most of the fish feed drying equipment directly puts the fish feed from the inlet, and uses the method of blowing at the bottom to dry. The disadvantage of this is that the fish feed falls directly from the top, resulting in uneven dispersion of the feed in the drying equipment, and due to the falling Time is off and becomes hard to dry enough. [0004] The traditional fish feed spraying equipment uses a high-pressure nozzle to spray high-pressure oil vapo...

Problems solved by technology

[0003] Most of the fish feed drying equipment directly puts the fish feed from the inlet, and uses the method of blowing at the bottom to dry. The disadvantage of this is that the fish feed falls directly from the top, resulting in uneven dispersion of the feed in the drying equipment, and due to the falling Time is off and is hard to dry enough

[0004] The traditional fish feed spraying equipment uses a high-pressure nozzle to spray high-pressure oil vapor into the fish feed in the spraying equipment to realize the spraying of fish feed. The disadvantage of this is that the spraying effect of the nozzle is not good, and the macromolecular oil is condensed together, resulting in poor spraying. Uniform and wasteful spray grease

[0005] In addition, the traditional fish feed dryer is separated from the spraying equipment, which not only increases the cost of the equipment, but also increases the processing cost and processing time due to the increase of the processing procedure.
