Abstract

FIELD: fodder production.

SUBSTANCE: meat-and-bone raw material, milled into a paste-like state, is mixed with a protein component and granulated. Protein component used is pea grain wastes, which are mixed with meat-and-bone paste at ratio of 1:1. Mixture is held for at least 60 minutes for water saturation of pea grain wastes in a paste-like meat-and-bone medium, after which the obtained composite mixture is milled, stirred until homogeneous and granules are formed using a lattice-knife type apparatus.

EFFECT: wider range of fodder products.

Description

The invention relates to feed production, in particular to methods for producing protein and mineral products.

There is a known method for preparing a protein-mineral feed product, including grinding meat and bone raw materials, mixing it with protein components in the form of flour and subsequent production of granules [EA14382 B1 Open Joint Stock Company "Slonim Meat Processing Plant" (BY) dated 10/29/2010].

The disadvantage of this method is the relatively high cost of the finished product, due to the significant costs of labor and money to obtain feed in the form of flour.

There is also a known method for preparing a protein-mineral product, including the preliminary preparation of protein pulp, its mixing with meat and bone paste and the production of granules [Patent RU No. 2486759, taken as a prototype].

The disadvantage of this method is the relatively high cost of obtaining the finished product, determined by the need for preliminary and costly production of the protein component in the form of flour.

An analysis of known similar technical solutions has shown that an important technical problem in this area is expanding the range of feed products with low production costs.

The technical result of the invention is to expand the range of feed products while reducing the cost of their production.

To solve this problem and achieve the stated result in the method of preparing a protein-mineral feed product, including mixing meat and bone raw materials, crushed to a paste with a protein component and subsequent granulation, pea grain waste is used as a protein component, which is mixed with meat and bone paste in a ratio of 1 :1, the mixture is kept for at least 60 minutes to saturate the pea grain waste in a pasty meat-and-bone medium, after which the resulting composite mixture is crushed, mixed until homogeneous and granules are formed using a lattice-knife type apparatus.

The inventive method allows, due to the water saturation of pea grain waste in a paste meat-and-bone medium, to reduce the resistance of the grain of destructible peas at least twice and to carry out its disintegration in the composition of the paste composition with a decrease in energy intensity of at least two times, without the presence of flour dust.

An example of the method.

In fig. 1 shows a technological scheme for obtaining a protein-mineral product in the form of granulate; Fig. 2 - hardware diagram of protein-mineral granulate.

The method is carried out as follows. A paste is preliminarily prepared from meat and bone raw materials using device 1 (Fig. 2), containing a grinding apparatus (IA) 2, a lattice-knife type. In this case, this device 1 has a removable module in the form of a pressing-granulating unit (PGU) 3.

According to Scheme I, meat and bone paste is prepared using IA 2, which enters the mixer in the required quantity. Pea grain waste in the form of grain or waste grains is fed into the same mixer 4 in the same quantity by weight. The resulting mixture is kept in its composition for at least 60 minutes, in the case of using pea feed grain. Then, after the semolina or grain is saturated with water, device 1 is switched on to mode II - obtaining meat-bone-pea granulate. For this purpose, device 1 is equipped with a PTU.

When working according to this scheme II (Fig. 2), the pre-prepared meat-bone-pea mixture is fed by dispenser 5, which is part of the mixer 4, into device 1, additionally equipped with PTU 3.

The mixture passing through the sieve-knife apparatus 2 disintegrates water-saturated pea grain waste, destroying its particles, which are intensively redistributed among the particles of meat and bone paste. Then, the resulting homogeneous mixture is formed into granules using PTU 3, and enters tray 6. Trays 6 are placed in drying oven 7, where the granules are dried and their humidity is brought to 8...10%. After this, the dry granulate is packaged, stored and sold to the consumer.

At the first stage, according to Scheme I, meat and bone paste is obtained using device 1. The paste, for example, in an amount of 100 kg is continuously fed into a working mixer 4. Pea grain waste is also supplied here, for example in the form of waste grains in an amount of 100 kg . The grain, being in a paste medium, is saturated with water due to the phenomenon of mass exchange, as a result of which a duration of 60 minutes is sufficient and, accordingly, for peas - more than 60 minutes. At the same time, the resistance to destruction of the pea component (grains, grains) in the lattice-knife apparatus 2 is halved. Next, the meat-bone-pea mixture paste passes through a previously and additionally installed PTU 3, where granules are formed. Granules, according to scheme II (Fig. 2), accumulate in tray 6. Trays 6 are placed in a drying cabinet 7, for example, ESPIS-4 “Universal” with nine drying modes.

The dried granules are packaged, stored and sold to the consumer.

Compared with the prototype, the method of preparing a protein-mineral feed product will provide an expansion of the range of feed products containing proteins of animal and plant origin with the presence of calcium with a low cost of production, by reducing the resistance to destruction of moisture-saturated pea grain waste in the form of pea grains and waste grains.
