Feed fabricating method for special animal such as fox, ermine and raccoon dog

Abstract

The invention relates to a manufacturing method for animal feed, in particular to a manufacturing method for a special animal feed exclusively used in fox, mink and raccoon dog. The method has the advantages that: raw materials of corn and soybean meal required in the formula are bulked by a dry method or wet method and ground; the ground material is mixed with meat and bone meal and imported fishmeal, and then bulked again (by the dry method or wet method); the second bulking is completely different from other bulking methods for an annular space discharging mode is adopted in the discharging in front of a bulking machine in the second bulking and the bulking temperature is 100-130 DEG C, which not only realizes the aim of sterilization and curing, but also avoids breaking the nutritional factors of the materials due to over-high temperature; the product produced by the process has high bulking degree, good water binding capacity, good palatability and thorough sterilization. The premix materials are added and mixed twice to avoid reducing the effect caused by heating.

Description

technical field [0001] The invention relates to a manufacturing method of animal feed, in particular to a manufacturing method of fox mink and raccoon special animal feed. Background technique [0002] With the improvement of people's living standards and the increase in demand for foreign trade, the consumption market for special animal fur is expanding day by day, which has led to the development of the special animal breeding industry. The breeding scope is mainly concentrated in Shandong, Hebei and the three northeastern provinces. According to incomplete statistics, the annual consumption of special animal feed is more than 1 million tons. Because fox mink and raccoon dogs are carnivorous animals, the traditional breeding mainly feeds miscellaneous fish, poultry, duck and other slaughtering waste and meat offal. With the expansion of breeding volume, the original feed resources are difficult to meet the demand, and people start to formulate full-price feeding. special ...

AI Technical Summary

Problems solved by technology

The feed produced by the above method has poor expansion degree, poor water holding capacity and palatability of the product. At the same time, there are some problems in the safety of the feed due to incomplete sterilization. To solve the above problems, we have invented a new special animal feed processing method.

[0003] The discharge nozzles of the existing extruders all adopt the single-mode hole or multi-mode hole discharge method. This kind of processing equipment can no longer meet the processing requirements of the current new feed. Specifically, in the traditional feed processing, Especially for single raw materials such as soybeans and corn, the puffing process of the raw materials adopts a single-die hole discharge method, and the soybeans or corn are puffed and then mixed with other raw materials to make products; With the changes in the breeding structure, for economic animals such as ferrets, the traditional feed can no longer meet the requirements. The raw material composition and ratio of the feed have undergone great changes, and the processing technology has also had special requirements. There are many shortcomings and deficiencies in the way of die hole discharge. First, the output of the product is limited (one ton per hour for single die hole discharge), and the energy consumption is large; High pressure can lead to excessive processing of raw materials, reducing the nutritional content of feed products
