Abstract

FIELD: food industry; feed production.

SUBSTANCE: invention relates to the food industry and feed production, in particular to a method for preparing a pasty product based on grain raw materials. To obtain the product, the initial grain raw material is pre-soaked in an aqueous solution of vitamin and (or) mineral substances up to 50% of their water saturation. Then the water-saturated grain raw material is sent for disintegration in a grinding device containing at least a 4-stage lattice-knife apparatus.

EFFECT: use of the invention will reduce the cost of energy, labor and funds associated with the production of pasty products as well as losses from the presence of flour fraction.

Description

The invention relates to feed production and, in particular, to methods for preparing feed products based on grain raw materials.

A known method of preparing pasty feed in the form of liquid mixtures of feed with water / Melnikov S.V. Mechanization and automation of livestock farms. Leningrad: Kolos-1978. - 560 p. Page 222-224 Analog/.

The disadvantages of this method are:

- firstly, a large amount of the resulting flour fraction when grinding dry grain raw materials with a hammer-lattice apparatus, leading to its losses, dustiness, explosiveness, and in connection with this, the need to use an aspiration system;

- secondly, due to the microdoses of vitamins and microelements introduced into the crushed dry mass, a long and thorough mixing of them with fillers is required when obtaining combined feeds, which is associated with high energy, labor and cost;

- thirdly, mixing ready-made dry feed with water to obtain liquid paste-like masses also requires additional labor, energy and money;

- fourthly, grate-hammer devices used in crushers do not allow crushing wet grain.

There is also a method for preparing liquid pasty feed according to a scheme involving crushing dry grain in hammer mills, roller mills and other devices, followed by mixing them with vitamins, minerals (premixes) and water in a certain ratio / Melnikov S.V. Mechanization and automation of livestock farms. Leningrad: Kolos-1978. - 560 p. Page 215. - Combination of the first and third typical technological schemes. Prototype/.

The disadvantages of this method are the relatively high costs of labor, energy and money due to the multi-operational production to obtain a finished pasty product, the heterogeneity of the resulting mixtures, and the need for high dosing accuracy when adding vitamins and trace elements to a dry flour filler obtained in an energy-intensive way by disintegration using a lattice - hammer apparatus, which is not operational on wet grain.

The objective of the present invention is to reduce the cost of energy, labor and funds associated with the production of pasty products by eliminating the multi-operational nature of their production, as well as losses from the presence of a flour fraction associated with the operation of a sieve-hammer apparatus for grinding dry grain components.

This is achieved by the fact that the initial grain raw material is pre-soaked in an aqueous solution of vitamin and (or) mineral substances to 50% of their water saturation, followed by disintegration in a device containing at least a 4-stage lattice-knife apparatus.

The technical result lies in the fact that such a preliminary soaking of grain raw materials, as well as the use of impactless destruction of the product, makes it possible to reduce the cost of energy, labor and funds, by eliminating operations for aspiration, dry, highly accurate dosing and mixing of the finished compound feed with water, at the final stage of obtaining liquid paste product.

In FIG. 1 shows the technological scheme for the implementation of the proposed method. In FIG. 2 hardware diagram of the line for the production of paste.

The method is carried out as follows.

At the first stage, an aqueous solution of vitamins or microelements is prepared in container 1 (Fig. 2), according to accepted zootechnical standards according to the scheme shown in (Fig. 1).

Then, the initial grain raw material, for example, seeds or wheat, or barley, or oats, or millet, or sorghum, or soybeans, or peas, etc., is placed in container 1.

Upon reaching the seeds of 50% water saturation, they are fed by auger - 2 into the hopper - 3 of the paste maker, containing the screw - 4 and the 4-stage lattice-knife apparatus - 5.

Further, moistened and enriched grain raw materials are fed by a screw - 4 to a 4-stage lattice-knife apparatus - 5, where it is intensively destroyed without forming a flour fraction. Then, the paste-like and enriched mass, crushed to the required grinding module, enters the container - accumulator - 6, and then to the consumer.

In principle, this method is a dual-purpose method - both for the production of feed and food products and semi-finished products.

Example. At the first stage, an aqueous solution of either ascorbic or succinic acid, etc., or a solution of calcium or magnesium or their salts CaCl ₂ and MgCl ₂ , etc. is prepared in tank 1. Then, prepared seeds are placed in the resulting solution, for example, or wheat, or barley, or oats, or millet (millet), or sorghum, or soybeans, or peas, etc. or their combinations.

When the seeds reach 50% water saturation, they are fed by an auger - 2 into a hopper - 3, from where they are transported by a screw - 4 into a 4-stage lattice-knife apparatus - 5, made, for example, like a meat grinder-top, without the formation of a flour fraction .

The finished enriched pasty product is accumulated in a container - 6 and, further, is sold for its intended purpose.

Thus, the proposed method, at least 2 times, allows to reduce the cost of energy, labor and money compared to traditional methods, by eliminating the operations of aspiration and thorough mixing of dry compound feed with vitamins and minerals in their dry form with the replacement of the lattice-hammer apparatus on a 4-stage lattice-knife apparatus, which allows to obtain a degree of grinding within λ=12-15 units. and more.
