Method for preparing fish feed from vinasse

Abstract

The invention relates to a method for preparing a fish feed of vinasse. The method comprises the following steps: respectively thoroughly boiling corn grit and wheat; uniformly mixing vinasse having a vinasse liquid with the cooked corn grit, the cooked wheat, cereal flour, puffed corn flour and distiller's yeast in proportion, and compacting the obtained mixture to form a vinasse fish feed blank; integrating a one-way exhaust valve on an inner packaging bag, and arranging a ventilating hole in an outer packaging bag; and filling the inner packaging bag with the vinasse fish feed, carrying out hot pressing sealing by a vacuum packaging machine, pasteurizing the feed blank, packaging the inner packaging bag in the outer packaging bag, sealing the outer packaging bag, and carrying out storage, logistic delivery and shelf life fermentation alcoholization to obtain the high-protein vinasse fish feed. The fermentation alcoholization process of the vinasse fish feed is set in the storage, logistic delivery and shelf life stage, and the inner and outer packaging bags are packaging bags and also are small production devices, so the production cycle is shortened, the capital construction investment is saved, the production cost is reduced, the mellowness and the attractiveness to fish of the above product are improved, and the product can be used as a fish luring material and an explosive bait for general fishers to fish large fish.

Description

technical field [0001] The invention belongs to the field of feed preparation, in particular to a method for preparing fish feed from distiller's grains. Background technique [0002] Distiller's grains, also known as red grains, distiller's grains, etc., are the residues left after brewing rice, corn, wheat, sorghum, etc. Due to the different raw materials and methods of wine making, the ingredients are also different. The crude protein content can reach about 25%, which is about 2 to 3 times higher than the corn protein content. It also contains a variety of trace elements, vitamins, yeast, lysine Acid, methionine and tryptophan, etc., because there is still a considerable amount of ethanol remaining, so it has a greater wine aroma. [0003] In addition, the fishing population in my country has reached more than 200 million, and about one-third of them like to catch large fish such as carp, grass carp, and herring in natural and farmed waters. The demand for nest material...

AI Technical Summary

Problems solved by technology

[0006] 1. For cattle or other animals as feed, it is difficult to match green feed, which makes it difficult to expand the scale of cattle or other animal breeding

[0007] 2. The moisture content of distiller's grains is as high as 40% to 50%, not only the logistics cost is high, but also the problem of environmental pollution caused by spilling and dripping

[0008] 3. Due to the high moisture content and the high cost of drying treatment, its further processing and utilization are limited

[0009] 4. Our country has a vast territory. Both fish farmers and fishermen are far away from liquor production areas. Limited by the storage, transportation and corresponding costs of distiller's grains, the majority of fish farmers and fishermen cannot buy distiller's grains.

The problem of this method is that the capital investment is large, the production personnel are many, the cost is relatively high, and the production cycle is long.
