Production process method of aquatic feed

Abstract

The invention, which relates to the technical field of aquatic feed production, discloses a production process method of aquatic feed. The method comprises the following steps of raw material receiving and primary coarse crushing, primary batching and mixing, secondary crushing and secondary batching and mixing, granulation section execution, fish feed finished product treatment and packaging, shrimp feed finished product treatment and packaging, granule puffing section and finished product treatment. The production process method has the beneficial effects: the operation is convenient; various raw material varieties can be involved; the batching precision is high, the crushing fineness is fine, and the mixing uniformity requirement is high; the technological process can be simplified; with full utilization of functions of equipment, unnecessary equipment investment and plant construction investment can be saved; the construction period is shortened, the yield is increased, and the production cost is lowered; and the production line process can be used for producing 8 to 10 t / h of granular fish feed, 8 to 10 t / h of granular shrimp feed and 3.5 to 4.5 t / h of high-grade puffed aquatic feed at the same time.

Description

technical field [0001] The invention relates to the technical field of aquatic feed production, in particular to a production process for aquatic feed. Background technique [0002] Aquatic feed includes: fish meal, shrimp head meal, shell meal and so on. Aquafeed is bait specially provided for aquatic animal breeding. According to feeding species, aquatic feed can be divided into fish feed, shrimp feed and crab feed; according to feed characteristics, it can be divided into compound feed, concentrated feed and premixed feed. The raw materials for the production of aquatic feed are mainly composed of fishmeal, grain raw materials and oil, and fishmeal and grain raw materials often account for more than 50% of the feed cost. [0003] Generally speaking, the development of China's aquatic feed industry has gone through three stages. The first stage was before the 1980s, when the feed was basically natural feed; the second stage was from the 1980s to the end of the 1990s. It...

Problems solved by technology

[0004] In the past, the production process of aquatic feed was cumbersome to operate, could not involve a variety of raw materials, low batching precision, large crushing fineness, low mixing uniformity requirements, could not simplify the process flow, could not make full use of equipment functions, and easily caused equipment investment and plant construction investment, the construction period is long, which reduces the output and increases the production cost
