Problems solved by technology

Chicken manure feed is not mass-produced in various existing processes, and limited by certain conditions, it cannot be used as protein feed for various animals
The conventional chicken manure feed production process is mainly the fermentation method, which is fermented by straw starter or em bacteria or gold baby fermentation aids. In addition, there are physical methods and chemical methods, but these methods take a long time to process and emit odor. It pollutes the environment and causes a large loss of nutrients, so it is not suitable for large-scale production

Abstract

The invention provides chicken manure puffing processing technology. The chicken manure puffing processing technology comprises the following steps: fresh chicken manure is adopted as raw materials, and the water content of chicken manure reaches to 25%-40% after the chicken manure is dried by a dryer; feeding is achieved through a feeding device; through hardening and tempering of a conditioner, steam is added for hardening and tempering, the add amount of the steam is 30-50%, working pressure of a boiler is 0.8-2MPa, hardening and tempering time is 180-300s; and puffing is carried out through the adoption of a single threaded rod extrusion type bulking machine, wherein pressure of a working chamber of the bulking machine is 150-300MPa, the temperature is 100 DEG C-200 DEG C, the rotating speed of a threaded rod is 300-450 revolutions per minute, length-diameter ratio of the threaded rod is 15-25:1, and the compression ratio is 2-5:1. The crude protein content, pepsin digestibility, the protein dissolution rate and amino acid average digestibility are all greatly promoted, and at the same time, the productive process is clean and environment-friendly, environmental pollution is reduced, production and processing cycles are short, the processing technology is suitable for large-mass industrial production, and economic benefits of enterprises are improved.

Description

technical field [0001] The invention belongs to the field of feed processing, and in particular relates to an expansion processing technology of chicken manure. Background technique [0002] Chicken manure has the highest protein content in animal excrement. Chicken manure is a cheap low-energy protein feed, which can greatly improve the economic benefits of animal husbandry, reduce pollution, purify the environment, and form an ecological industrial chain. Chicken manure feed is not produced on a large scale in the existing various processes, and is limited by certain conditions and cannot be used as protein feed for various animals. The conventional chicken manure feed production process is mainly the fermentation method, which is fermented by straw starter or em bacteria or gold baby fermentation aids. In addition, there are physical methods and chemical methods, but these methods take a long time to process and emit odor. Not only pollute the environment but also cause ...
