Preparation method of corn kernel fermented feed

Abstract

The invention discloses a preparation method of a corn kernel fermented feed and relates to a preparation method of a fermented feed. The preparation method disclosed by the invention solves the technical problem that loss of nutritional ingredients is severe as the kernel crushing method ferments the corn kernels and the kernels are easily corrupted if being stored. The preparation method comprises the following steps of: I, threshing the corn kernels, the water content of which are 25-30%, to obtain the corn kernels; II, dissolving sodium propionate in water to obtain a sodium propionate aqueous solution; III, uniformly spraying the sodium propionate aqueous solution to the corn kernels, uniformly stirring the corn kernels and the sodium propionate aqueous solution, then compacting and sealing the mixture, and covering the surfaces of the compacted corn kernels with 10-20cm soil or a weight; and IV, storing the corn kernels for 1 month at normal temperature to obtain the corn kernel fermented feed. The preparation method disclosed by the invention is simple in used equipment and not severe in demand on fermenting condition. The cost of raw materials of an additive for treating 1 ton of the corn kernels is about 60 yuan. The preparation method is simple to operate and is of extremely promotional meaning. The preparation method disclosed by the invention belongs to the field of preparation of the fermented feed.

Description

technical field [0001] The invention relates to a method for making fermented feed. Background technique [0002] Corn is the main food crop and feed raw material in my country. When harvested, the ear of corn has bract leaves, and the original moisture is generally high, generally 25% to 30% or even higher in Northeast China and Inner Mongolia. At the same time, the embryo of corn is larger, accounting for about 1 / 3 of the total volume of corn grains. The embryo also contains more than 30% protein and more soluble sugar, so it has strong hygroscopicity and strong breathing. Therefore, in the high-moisture corn after harvesting, at a suitable temperature, the mold in the embryo will proliferate in large numbers, local fever and mildew are quite common, and the loss of nutrients is serious. Fever and mildew are very common after warming up in the spring of the second year, causing a lot of corn to be wasted in vain. As the Northeast China is the main producing area of ​​cor...

Problems solved by technology

Fever and mildew are very common after warming up in the spring of the second year, causing a lot of corn to be wasted in vain

However, in the prior art, the fermented corn grains adopt the grain crushing method, which leads to serious loss of nutrients, and the problem of corruption is prone to occur after storage.

And the production conditions are strict, and it is not easy for general users to operate
