Method for preparing fish feed and fish attracting bait from distillers' grains

Abstract

The invention relates to a method for preparing a fish feed and a fish attracting bait from distillers' grains. The method comprises the following steps of stirring the distillers' grains, wheat bran, rice bran, corn grits and a binder, performing homogenization, performing soaking, performing evaporation for controlling moisture, forming balls / pellets, performing high-temperature flash consolidation and performing sterilizing. The distillers' grain fish feed pellets prepared by the method are dissolved and dispersed when being in contact with water, the wheat bran, the rice bran and part of tiny distillers' grains float in a water body, and large distillers' grains and the corn grits settle down into water, so that three-dimensional feeds are obtained, and self adult fish and adult fish in different water layers can effortlessly suck the feed. The distillers' grains, the wheat bran and the rice bran are recycled, waste is turned into wealth, and flash-drying and sterilizing are performed at high temperature; and residual heat is recycled, the heat utilization efficiency is high, discharge of three industrial wastes does not exist, the utilization way of the distillers' grains is extended, and superior cheap feeds are provided for large-scale freshwater fish and fish attracting baits for large fish are provided for vast fishermen.

Description

technical field [0001] The invention belongs to the field of feed preparation, and in particular relates to a method for preparing fish feed and fishing nest material 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 that of corn. It also contains a variety of trace elements, vitamins, yeast, lysine , methionine and tryptophan, etc., because there is still a considerable amount of ethanol remaining, so it has a greater wine aroma. [0003] Distiller's grains are often used as feed for cattle or other animals. However, directly feeding cattle or other animals with distiller's grains not only does not fully utilize the nutritional value, but also has...

AI Technical Summary

Problems solved by technology

[0007] 1. For cattle or other animal feed, it is difficult to match silage, which makes it difficult to expand the scale of cattle or other animal breeding

[0008] 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

[0009] 3. Due to the high moisture content and the high cost of drying treatment, its further processing and utilization are limited

[0010] 4. Our country has a vast territory. Both fish farmers and fishermen are far away from liquor production areas. Due to the storage, transportation and corresponding cost constraints of distiller's grains, the majority of fish farmers and fishermen cannot buy distiller's grains.

Because the fish are distributed in layers in the water, the fish feed prepared by this method is difficult to meet the needs of different fish when used, and it is inconvenient to be used as a fish lure nest material for catching large fish
