Spray bursting type processing method of fish soluble

Abstract

The invention discloses a spray bursting type processing method of fish soluble, comprising the following steps of: preparing meal and discharging the fish meal; feeding the fish meal into a spray bursting tank, closing and sealing a discharge valve of the spray bursting tank, cooking and boosting until the pressure gradually rises to 0.5-2.5MPa, keeping the pressure for 2-20 minutes; preparing to discharge and spray bursting the discharged meal; quickly opening the discharge valve of the spray bursting tank; spraying the fish meal from the spray bursting tank to a fish meal collecting tank so as to generate the instant spray bursting phenomenon; and making the fish meal into the uniform soluble with fine granular size and collecting the fish soluble. Compared with the prior art, the invention has the advantages that the spray bursting type processing method of the fish soluble has simple process flow and is convenient for operation; the fish soluble processed by the method has small and uniform granules; the quality of the fish soluble is upgraded to a new grade; and the fish soluble is a superior material for subsequently preparing high-quality fish meal, fish extract, fish peptone and fish protein organic fertilizer.

Description

Technical field: [0001] The present invention relates to the preliminary process of fish deep-processing products, that is, a method for pretreatment of fish feed, in particular, a spray-explosive processing method for fish paste. Background technique: [0002] In the process of deep processing of aquatic products such as high-quality fish meal, fish extract, fish peptone or fish protein organic fertilizer, there is a common process in the early stage, that is, the fish feed needs to be processed into fish paste, and then Then fish paste is processed into different products through different processes, such as: high-quality fish meal, fish extract, fish peptone or fish protein organic fertilizer, etc. For this process, it is called the fish feed pretreatment process or the spray explosion processing method of fish paste in the industry. There are two kinds of blasting processing methods for existing fish paste, one is raw material processing method: its work steps are: (1) ...

AI Technical Summary

Problems solved by technology

In actual production, people in the industry are well aware that it is difficult to crush fish without dehydration, especially making it into fish paste with uniform particles and small particle size; this is because there are a lot of muscle in fish body. Fibril protein and other proteins have gel characteristics, strong hydrophilicity and cross-linking ability, and are combined with each other by hydrogen bonds, making them very sticky and slippery. It is difficult for ordinary crushing equipment to crush muscle fibers. There are still many strips of muscle fibers in the fish paste produced by the raw material processing method, which cannot meet the ideal requirements of fish paste with uniform particles and small particle size; although the clinker processing method is easier to crush than the raw meal processing method, it needs to be heated. Grinding for many times will increase the cost and lower the quality of fish paste

Seriously affect the processing of subsequent products, such as affecting the quality and quality of high-quality fish meal; reduce the hydrolysis rate and yield of fish extract or fish peptone; reduce the full utilization rate of fishbone and fish bones when making fish protein organic fertilizer
