RU2486759C1 - Method for preparation of protein and mineral fodder product - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: invention relates to fodder production, in particular, to methods for preparation of soya component based fodders. The protein and mineral fodder product preparation method involves milling meat and bone raw material represented by poultry by-products and the raw material mixing with a protein component in the form of soya flour and subsequent formation of granules. The meat and bone raw material is represented by a paste of poultry by-products represented by legs, heads and necks at a ratio of 1:1:1; the paste is preliminarily prepared by way of two-fold milling - coarse and fine, in a paste-producing chopper. The protein component is represented by full fat soya flour; the ratio of flour to paste is equal to 1:1 while mixing is performed simultaneously with components supplying for formation of granules; the dry substances content is conditioned to 90-92%.

EFFECT: invention implementation allows to reduce the cost of the product manufactured and enhance the product biological value.

Description

A known method of preparing a protein-mineral product, including the production of meat and bone meal by grinding meat and bone raw materials, followed by bringing it to a certain dry matter content, a protein component in the form of soybean meal (fat-free) and other components, mixing them (recipe PK - 22 - 3 - 89 tab. 247 p. 250-251 Reference “Compound feed, feed additives and WMS”, edited by V. Krokhina, Agropromizdat. - 304 pp. Analog).

The disadvantages of this method are the relatively high cost of obtaining meat and bone meal and fat-free soybean meal, due to the need to dry the meat and bone paste to turn it into flour, as well as heat treatment of soybean meal to remove the solvent after extracting the oil from the soy petal. Moreover, after extracting soybean oil from the soybean petal, vitamin E is absent in the soybean meal, as it is extracted together with the oil.

There is also known a method for producing a protein-mineral feed product, including grinding meat and bone raw materials in the form of poultry by-products, mixing it with a protein component in the form of soy flour and the subsequent formation of granules (see EA 14382 B1 (Slonim Meat Processing Plant Open Joint-Stock Company (BY)) , October 29, 2010, formula Prototype).

The disadvantages of this method are the relatively high cost of obtaining the composition by-product raw materials + soy flour, as well as the relatively low biological value of the composition.

The objective of the present invention is to obtain a protein-mineral product of relatively low cost, increased biological value due to the presence of vitamin E with high antioxidant activity.

This is achieved by the fact that upon receipt of a protein-mineral product, including grinding meat and bone raw materials with subsequent bringing to a certain dry matter content and mixing it with a protein component, paste from poultry by-products in the form of legs, neck and heads in a weight ratio is used as meat and bone raw materials 1: 1: 1, and as protein - non-fat soy flour, taken in a ratio of 1: 1, and mixing is carried out simultaneously with the supply of components for the formation of granules.

The technical result consists in the fact that this method allows, by averaging the moisture in the paste and soy flour, to halve the energy costs of the drying process and to obtain a finished product containing the vitamin-mineral complex E + Ca + P - (vitamin E + calcium + phosphorus), which provides the product with high antioxidant activity.

Figure 1 shows a diagram of the production of protein-mineral granulate, Figure 2 is a processing line for the preparation of protein-mineral granulate.

The method is as follows.

From offal raw materials - legs, neck, head, taken in a weight ratio of 1 kg: 1 kg: 1 kg, paste is prepared by double grinding - coarse and fine (see figure 1 and figure 2) on the grinder-pasta maker "Volgar -5". Paste with a screw 2 is fed into the hopper batch 3, and from it into the mixer granulator 5. Here also is fed non-fat soy flour from the batch in the ratio of 1 kg: 1 kg. The ratio of these offal as 1: 1: 1 provides the required solids content in the resulting meat and bone paste from 40% to 50%. Moreover, mixing a paste with such a solids content and non-fat soy flour with a solids content of 90% in a ratio of 1 kg: 1 kg allows you to get a protein-mineral composition with a solids content of from 65% to 70%. Accordingly, when removing moisture by drying, with such a dry matter content in the resulting protein-mineral compositions, less energy will be required.

At the same time, with the indicated ratios in the offal raw materials, as well as in the composition (weight), there is paste: non-fat soy flour = 1: 1, the protein content is: - 50.2%, Ca = 18 g, P = 7.5 g and vitamin E = 400 mg per kilogram of product.

Moreover, the solids content in the range of 65-70% is optimal for the formation of high-quality granules. At values below 65%, the granules disintegrate and do not hold their shape, and above 70% they disintegrate.

The granules formed by the mixer-granulator 5 are accumulated in the mesh tray 6, after which the tray is placed in the versatile dryer 7 - ESPIS-4.

In the dryer, the solids content is brought to the 90-92% required by technical specifications.
