Description

one

This invention relates to agricultural fodder production, more specifically to the processing of green and mature stalked fodder.

There is a known method for preparing animal feed, which includes grinding green plants and straw, mixing and grinding components, and then feeding the resulting mixture or ensiling it 1.

The disadvantage of this method is that during the preparation of the feed mixture and especially during ensiling, irrecoverable losses of green plant sap are formed, which is an important raw material for obtaining protein concentrates or protein-vitamin supplements (BVD) used in non-scorpid animals and poultry rations. In addition, the juice flowing from the silo pollutes the environment.

A known method of preparing feed for animals from highly moist feed products, mainly green plants, involves grinding the raw material and dividing it by pressing into liquid and solid fractions in order to obtain concentrates from them 2.

The disadvantage of this method is that about 50% of the juice is extracted from the crushed green mass by pressing in a screw press. The resulting pulp is enriched in non-proteinaceous compounds with synthetic compounds, carbohydrates, etc. feed only after pressing, i.e. additional resources are spent on

10 purchase of special mixers, their operation and maintenance.

The purpose of the invention is to simplify the process, intensify the juice production and reduce the cost of the final products.

This is achieved by adding crushed coarse feeds or their waste in an amount of 30-60% of

20 weight green mass. As roughage, for example, chopped straw, shredded waste of roughage, corn stalks, etc. are used. products.

Example. Green plants crushed in the field are transported by mobile transporter to the workshop of preparation of protein-vitamin additives. Chopped coarse feeds, such as straw, are delivered here. Is30

The feed components, for example, 30% i chopped straw and 70% green mass, are mixed and loaded into a press bin. The chopped straw in this case is an auxiliary pressing material, which contributes to the intensification of juice production. In the pressing chamber, the chopped straw is the conductor for moving the juice toward the filter wall. At the same time, intensive mixing of the starting components takes place in the pressing chamber.

which provides a uniform mixture, then directed to feed the animals. From the obtained juice, protein-vitamin concentrates are then prepared. The use of an auxiliary pressing material (straw chopping) provides an increase in juice yield on serial equipment without additional costs.

The table shows the results of the above experiments on the selection of juice, depending on the amount of chopped straw in the initial mass. I

Claims (2)

Claim 1. A method of preparing animal feed from high-moisture feed products, including grinding the green mass and separating it by pressing into liquid and solid fractions, different τθν ”, which, in order to simplify the process and intensify juice production before pressing, crushed coarse feed is added to the green mass or their waste in an amount of 30-60% by weight of the green mass. 2. The method of pop. 1, distinguishing with the fact that as a roughage they use a section of straw, cereal crops or their waste.
