Novel process for producing feed

Abstract

The invention relates to a novel process for producing feed, which belongs to the technical field of feed production. In the novel process the processing sequence for raw materials is adjusted according to the temperature resistant performance of the raw materials, the primary granulating procedure is improved, and a secondary granulating procedure is added. The process comprises the following steps: 1. primary granulating: pulverizing corn, bean pulp and other large-proportion high-temperature-resistant raw materials, carrying out high temperature treatment, granulating in a granulator, and cooling to obtain the primary granules; 2. secondary granulating: repulverizing the primary granules, adding sucrose, whey powder, vitamins, trace elements, medicinal additives, enzyme preparation and other raw materials, mixing, granulating at low temperature, and cooling to obtain the secondary granules; and 3. product inspection, packaging and warehousing. In the invention, the primary high temperature granulating ages most raw materials, and the secondary granulating is carried out at low temperature, thereby preventing vitamins and other additives from being destroyed by high temperature, and enabling the raw materials susceptible to high temperature to not easily be pasted. Thus, the particle hardness of the feed is improved, the breeding cost is reduced, the production benefit is enhanced and the feed has favorable mouth feel.

Description

technical field [0001] The invention belongs to the technical field of feed production. technical background [0002] With the development of animal nutrition and livestock and poultry breeding, people have gradually realized that not only the ratio of nutrients will affect the utilization rate of livestock and poultry feed, but also the processing of feed, such as crushing, granulating, puffing, etc. It also affects the utilization efficiency of various nutrients in feed. Therefore, the organic combination of animal nutrition and feed processing can make full use of the nutritional value of feed and promote the healthy development of animal husbandry. [0003] At present, the production process of one-time granulation is adopted in feed production, and various feed raw materials and additives are crushed and mixed, and then granulated directly. The problem with this production process is that the processing temperature is relatively high. Although the problem of feed matur...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new feed production process to solve the problem that the processing temperature of the prior art is relatively high, and vitamins, enzyme preparations and other materials that are not resistant to high temperatures will be damaged during the ripening process of the feed, causing a part of nutritional loss; and the feed contains Raw materials such as sucrose and whey powder, high-temperature granulation may easily cause hardening of feed granules, poor palatability and other problems
