Method for preparing biological feed from arrow root starch processing waste residue

Abstract

The invention discloses a method for preparing a biological feed from arrow root starch processing waste residue. The biological feed is prepared from the following raw materials in percentage by weight: 50 to 55 percent of arrow root starch processing waste residue, 20 to 30 percent of oil bran or wheat bran, 8 to 10 percent of corn flour, 8 to 15 percent of bean pulp, 0.1 to 0.2 percent of ferment bacterium, 0.2 percent of brown sugar, 2 to 3 percent of fish meal, 0.5 percent of urea, 1 to 1.5 percent of calcium superphosphate, 0.1 percent of common salt, copper sulfate, ferrous sulfate andzinc sulfate, wherein every ton of feed comprises 105g of copper sulfate, 105g of ferrous sulfate and 105g of zinc sulfate; and the feed is prepared by the following steps of: mixing the raw materials for 10 to 15 minutes; controlling water content to be 45 to 50 percent; uniformly mixing the raw materials, stacking the raw materials in a strip with width of 2 to 3m and height of 1.5 to 2.0m and performing anaerobic fermentation for 2 to 3 days; and drying the obtained product at the temperature of between 55 and 65 DEG C, or squeezing, granulating and drying at the temperature of between 55 and 65 DEG C. In the method, the arrow root starch processing waste residue serving as an organic waste is fully utilized, the high-efficiency and high-quality biological feed is produced, the production cost and the environmental cost are reduced, the environment is protected and the development of the ecological breeding is promoted.

Description

technical field [0001] The invention relates to a method for utilizing enzyme bacteria to process waste residues from cassava starch processing to produce biological feed. Background technique [0002] Cassava is one of the three largest potatoes in the world and is widely cultivated in tropical and subtropical regions. In the subtropical region of my country, cassava is the fifth largest crop after rice, sweet potato, sugar cane and corn. In 2008, the planting area of ​​cassava in my country reached 430,000 hectares, and the output of fresh potato reached 8.57 million tons. , the area yield is second only to tropical fruits, sugar cane and rubber. After the cassava is processed into starch and alcohol, about 75% of the quality cassava residue (about 6.42 million tons) is left over, which is very large in quantity. Cassava residue contains a large amount of cellulose, hemicellulose and lignin, etc., and has a high crude fiber content, which cannot be decomposed by the dig...

AI Technical Summary

Problems solved by technology

Cassava residue contains a large amount of cellulose, hemicellulose and lignin, etc., and has a high crude fiber content, which cannot be decomposed by the digestive juice and enzymes of pigs and other livestock and poultry. Less nutrients, poor palatability

In addition, fresh cassava residues are not easy to preserve, and will turn yellow or black within 1 to 2 days (aflatoxin pollution), which often causes poisoning and frequent disease after feeding to animals, which seriously restricts the resource utilization of cassava residues. The slag is discarded and rotted to pollute the environment and waste resources. Therefore, it is of great significance to rationally develop and utilize these organic waste resources and develop a circular economy.
