Embodiment Construction

[0039] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0040] A method for processing hydrolyzed fish meal, characterized in that it comprises the steps of:

[0041] A, remove the impurities in the raw fish;

[0042] B. The raw fish from which impurities are removed is pulverized by a pulverizer;

[0043] C, put the pulverized raw fish in the cooking machine for cooking;

[0044] D. Put the boiled raw fish in a degreasing machine for degreasing, and separate the water and oil mixture produced in the degreasing process from the fish meat;

[0045] E. Send the water and oil mixture to the separator for separation to produce fish oil and fish liquid, and send the fish meat to the press for pressing to form a pressed cake;

[0046] F. Transport the fish liquid and pressed cake ...

Abstract

The invention provides a processing method of hydrolysis fish meal, and belongs to the technical field of processing of fish meal. The processing method of hydrolysis fish meal disclosed by the invention comprises the following steps of A, removing impurities from raw fish; B, crushing the raw fish; C, cooking the crushed raw fish; D, performing defatting treatment on the cooked raw fish; E, separating a moisture and fat mixture to produce fish oil and fish liquid, and squeezing the fish meat to form squeezed cakes; F, mixing the fish liquid with the squeezed cakes to form fish meat pulp; G, transporting the fish meat pulp into a crushing pump, and performing one-step crushing; H, transporting the fish meat pulp after being crushed with the crushing pump into an enzymolysis jar, and performing enzymolysis so as to obtain enzymolysis fish thick pulp; I, performing vacuum concentration on the enzymolysis fish thick pulp so as to obtain high-concentration enzymolysis fish thick pulp; andJ, performing vacuum drying on the high-concentration enzymolysis fish thick pulp so as to obtain the hydrolysis fish meal. The hydrolysis fish meal produced by the method is high in quality; and besides, before the fish oil is enzymolysis, the quality of separated fish oil is good.

Description

technical field [0001] The invention belongs to the technical field of fish meal processing, and relates to a method for processing hydrolyzed fish meal. Background technique [0002] Due to the limitation of drying technology, hydrolyzed fishmeal technology has high production cost and low production efficiency. The traditional drying of hydrolyzed fish meal is to use spray drying technology, but this technology has high equipment cost, low efficiency, high processing requirements and higher cost. [0003] In addition, since enzymatic hydrolysis technology has just begun to be used in feed and fish meal industries. Generally, the fish is crushed and directly heated and enzymatically hydrolyzed, then thickened to obtain a fish thickener, and then the fish thickener is dried to obtain hydrolyzed fish meal. The hydrolyzed fish meal obtained by this method is of poor quality, and the quality of by-product fish oil is also bad. Contents of the invention [0004] The purpose...
