Fish fodder spraying and classifying device

Abstract

After fish fodders are processed into particles, the fish fodders are classified so that the fodder particles are enabled to be uniform and qualified; meanwhile, in order to avoid the waste caused by the condition that the fish fodders are easily wetted in water and scatter, water-proof oily substances are sprayed on the outside of the fish fodders, two working procedures are separated in the current fish fodder processing process, and the equipment manufacturing cost and the processing cost are increased. Aiming the problem, the invention provides a fish fodder spraying and classifying device, which comprises a discharging port, a classifying screen, a crushed aggregates recycling bin, a vibration device, a powdery fodder recycling pipe, an oil vapor recovery pipe, a qualified fodder bin, a powdery fodder recycling bin, an oil gas cooling bin, an oil water separation bin, a high temperature grease sprayer, a fan and a fodder classifying and spraying bin. The working procedures of classifying and spraying the fish fodders are performed at the same time, the equipment manufacturing cost is reduced, the processing working procedures are reduced, and the processing cost is thus reduced.

Description

technical field [0001] The invention relates to a feed processing device, in particular to a fish feed spraying and grading device, which belongs to the field of mechanical design. Background technique [0002] After the fish feed is processed into granules, it needs to be graded, and the unqualified feed granules are screened out through a sieve to ensure that the feed granules are uniform and qualified; The graded and selected feed particles also need to go through the spraying process, and the fish feed is sprayed with waterproof oily substances, so that the fish feed can not disperse for a long time in the water. Most of the fish feed processing processes separate the fish feed grading and spraying processes, which has the disadvantage of increasing equipment manufacturing costs and processing procedures, thereby increasing processing costs. Contents of the invention [0003] In view of the above problems, the present invention provides a fish feed spraying and gradin...
