Abstract

FIELD: fodders.

SUBSTANCE: invention relates to fodder production, in particular, to a method for preparation of a protein-concentrate additive. Method involves preparing a homogeneous mixture based on a nitrogen-containing and binder components, followed by moulding the composite mixture. Non-fat soya flour is used as the nitrogen-containing protein component, and as a binding agent - paste prepared on the basis of milled green mass of fodder crop Sosnowsky's hogweed, taken in phase preceding the budding, soya flour taken in weight ratio: paste from Sosnowsky's hogweed = 1:1. Mixture is moulded into granules at pressure P = 0.62 MPa. Obtained granules are dried in medium of active ventilation to 92 % of dry substances content.

EFFECT: invention usage allows to increase nutritive value of produced additive.

Description

The invention relates to feed production, in particular, to methods for preparing protein-concentrate additives of a given composition and properties.

A known method of preparing a feed additive, including the use of carbamide as a "protein" component, and molasses as a binder. [Mionchinsky PN, Kozharova L.S. Compound feed production. M: VO Agropromizdat. 1991 - 288 p. P. 96-98 (prototype)].

The disadvantage of this method is the use of a relatively toxic "protein" component - carbamide, with the simultaneous absence of a binder in its composition - molasses and vitamin complex C ++ E + β-carotene.

There is also known a method of preparing an amide-concentrate additive, including the supply of a nitrogen-containing component in the form of carbamide, carbohydrate, in the form of a grain component, as well as a binder component in the form of sodium bentonite (white clay) [V.V. Melnikov. Mechanization and automation of livestock farms. L .: Kolos. 1978 -560 p. P. 321-325 (analog)].

The disadvantages of this method is the use of a toxic component in the form of carbamide, as well as an expensive binder in the form of sodium bentonite. In addition, these components lack the vitamin complex C + E + β-carotene, which reduces the nutritional value of the finished product and its antioxidant activity. The technical problem to be solved by this invention is to increase the nutritional value of the finished product while increasing its feed safety and antioxidant activity.

This is achieved by the fact that fat-free soy flour is used as a nitrogen-containing protein component, and a paste prepared on the basis of the crushed green mass of the forage crop "Sosnovsky's Hogweed" harvested in the phase preceding budding, taken in a weight ratio - soy flour: paste from "Cow parsnip Sosnovsky" = 1: 1, the mixture is molded at a pressure of P = 0.62 MPa, and the resulting granules are dried in an active ventilation environment to 92% of the dry matter content.

FIG. 1 shows a technological scheme for the preparation of a protein concentrate additive, and FIG. 2 - structural and technological scheme of its production.

FIG. 2 shows: 1- dispensers; 2 - mixer; 3 - screw; 4 - nozzle; 5 - tray; 6 - drying cabinet.

The method is carried out as follows.

From the crushed green mass of the forage crop "Borshevik Sosnovsky", harvested in the phase preceding budding, a paste is prepared using a chopper-pasta-making machine of the "Volgar - 5" type. The resulting paste, not fat-free soy flour, at a ratio of 1: 1, is dosed (see Fig. 2) into the mixer - 2, from where the mixture is fed for homogenization, carried out by the screw - 3 of the pressing device. The homogenized mixture is molded at a pressure of P = 0.62 MPa by means of a nozzle - 4 and enters the tray - 5. The filled tray - 5 is installed in an oven, where the molded product is subjected to temperature drying in an active ventilation environment. The dried product is packaged, accumulated and sold to the consumer.

Example. Pre-obtained non-fatty soy flour and paste from the crushed green mass of the forage crop "Sosnovskogo Hogweed", harvested in the phase preceding budding using dispensers - 1 (Fig. 2) are fed in a 1: 1 ratio into the mixer - 2, where they are mixed. Further, the mixture is subjected to homogenization by means of a screw - 3 and pressed in a "soft" mode, for example, at P = 0.62 MPa, excluding denaturation of soy proteins for subsequent molding of the soybean-plant composition. Passing into the nozzle - 4, the resulting composition is formed, depending on the configuration of its section, into briquettes or, for example, cylindrical granules. The resulting product is accumulated on a mesh tray - 5, which is placed in a drying cabinet, for example, "ESPIS-4-Universal" with nine drying modes.

The active ventilation mode provides quick removal of moisture from the product, bringing the dry matter content in the product to 92%, ensuring the required strength of the granules.

At the same time, the ratio of flour and paste within 1: 1, gives an increased nutritional value to the product, compared with the prototype, 3.1 times in protein with the presence of vitamin C at 65.0 mg / 100 g, vitamin E at 7.52 mg / 100 g and β-carotene at 2.3 mg / 100 g (see table).
