Preparation method and preparation machine of cattle and sheep feed prepared by fermentation of potato residues and straw powder

Abstract

The invention relates to a preparation method and preparation machine of cattle and sheep feed prepared by fermentation of potato residues and straw powder fermented. The preparation machine comprisesa straw crusher, a straw dust remover, a mixing mixer, a mixing hopper and a quantitative briquetting sealing packaging machine which are connected in sequence through a conveying device, and the preparation machine also comprises a first auxiliary material hopper, a second auxiliary material hopper and a potato residue hopper which are connected with the mixing mixer through the conveying device, wherein a strain spraying device is arranged in the potato residue hopper. The preparation method of the feed provided by the invention is simple and easy to implement, and potato waste residues canbe well fermented. Agricultural wastes are fully utilized as main materials, the excellent cattle and sheep feed is produced on the basis of adding a small amount of grain auxiliary materials, and onthe premise of not adding antibiotics and hormones into the feed, the feed has a high nutritional value. Through microbial fermentation treatment, the protein content of the potato residues can be greatly improved, the fiber structure of coarse fibers can be improved, and palatability of the feed is improved.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a method for preparing feed for cattle and sheep fermented with potato dregs and straw powder and a preparation machine thereof. Background technique [0002] China is a big potato producing country, with an annual output of more than 60 million tons, and at least 4 million tons of potato dregs are discharged every year in potato processing and production. The water content of potato dregs is as high as 80%. It is not easy to store and transport, and it is easy to deteriorate and spoil. If it is directly discharged, it will not only waste resources, but also seriously pollute the soil, groundwater and atmospheric environment. The utilization and treatment of potato dregs is currently the production of high-protein feed, the second is the extraction of dietary fiber, and the third is the extraction of pectin and new adsorption materials. The most important use is to produ...

AI Technical Summary

Problems solved by technology

The production process is complicated, the operation is difficult, and the drying treatment of bean curd dregs requires a lot of energy consumption, the cost is high, and the nutrients mainly come from the added auxiliary raw materials. It is difficult to use the nutrients in potato dregs, resulting in the loss of nutrients in potato dregs , resulting in a waste of resources

[0003] In the past, in order to improve the growth-promoting effect of feed on livestock and poultry, people generally added some antibiotics and hormones to the feed. However, these drugs are used as feed additives by livestock and poultry. The livestock and poultry cannot completely decompose these additives, and the residues will have adverse effects on the human body.
