Manufacturing method using biological puffing technology to prepare pellet feed from straws

Abstract

The invention discloses a manufacturing method using a biological puffing technology to prepare a pellet feed from straws, equipment, and product. The manufacturing method is characterized in that straw powder, which has been processed by urea, is subjected to multi-enzyme pretreatment and biological fermentation, then the processed straw powder is evenly mixed with energy components, additives, and trace elements according to a specific ratio, and finally the mixture is granulated, dried and cooled to produce the puffed pellet feed for sheep and cows in a puffing machine and drying-cooling machine. The dry and yellow straws, which cannot be processed by common technology and have a low feeding value, are adopted to replace the grains, and the application range of agricultural straws is enlarged.

Description

[0001] (―) Technical field:

[0002] The invention relates to a feeding and feed processing method, in particular to a manufacturing method, equipment and product for preparing granular feed by applying biological and puffing technology to straw. (two) background technology:

[0003] The current straw treatment mainly focuses on the silage and ammoniation of corn straw, and a large amount of corncobs and wheat straw are seldom utilized due to their low feeding value. Moreover, the processed corn stalks can only be used as roughage, and still need to be supplemented with grain, which cannot fundamentally solve the contradiction between the development of animal husbandry and the "competition between humans and animals for grain". At the same time, the country produces about 600 million tons of agricultural straw every year, about 80% of which are discarded or burned, which can easily cause fires and pollute the environment. This kind of public hazard needs to be solved urgentl...
