Description

(54) FOOD CONSERVATION METHOD

one

The invention relates to agriculture and can be used in the preparation and preparation of feed.

A known method of preserving feed, for example, the preparation of grass meal, includes grinding the grass and artificially drying to 10-12% moisture content Tl.

The disadvantage of this method of preservation is high fuel consumption per unit of production (8085 kg of liquid fuel is consumed for evaporation of 1 ton of water), as well as a longer duration of drying the grass.

The closest in technical essence and the achieved result to the proposed method is the preservation of feed, including mowing and wiping the grass, drying it in rolls to a moisture content of 18-20%, then grinding and salting the table salt at the rate of 8 kg of salt per 1 ton of grass chaff 2

However, production checks show that this method of harvesting and storing hay does not exclude the possibility of focal areas of mold in various places of ricks, which is due to the uneven processing of the whole mass and having salt separation through the hay mass and separation of the salt fraction from the vegetable areas of stored feed.

The purpose of the invention is to reduce the energy consumption for the preparation of grass meal, grass chop or briquettes, improving the quality and improving the preservation of feed.

The goal is achieved by the fact that the chopped crushed green mass is salted before artificial drying at the rate of 315 3.5 kg of finely ground salt per 1 ton of raw material and dried to a moisture content of 22-25% with subsequent preparation of briquettes or bookmarking for storage in loose form .

The positive effect of salting the green mass before drying allows, during high-temperature drying, to dissolve the salt in the vegetable juice vapors and with this solution to treat the whole mass uniformly, ensuring uniform penetration of the salt solution directly into the plant mass. Salted herbs in this way are cut and dried to 20 -25% of moisture is well preserved without foci of mold damage, decay, etc., eagerly eaten by cattle. No sanding of herbs on flour or briquettes is good. They are stored only when dried to 10–12% moisture. Salting the feed at the rate of 3-3.5 kg of fine-salt salt per 1 ton of natural moisture feed eliminates the need for complete drying, which significantly reduces energy consumption and, consequently, fuel consumption, while reducing the time of thermal impact on the raw green mass, which also contributes to improving the quality of the harvested feed, preserving its nutrients, vitamins, which is essential for animal salt components. Example. Perennial crushy fire is awnless — they are mowed in phase, with ears with simultaneous grinding by a KSK-100 combine, and 3.5 finely ground salts are added to 1 ton of green mass, or saturated salt solution in the same ratio. The mass is evenly mixed with the salt. The salted green mass is transported to the drying unit and held for 1.5 hours. Then the mass is artificially dried on an AVM-1.5 to a moisture content of 23%, after which it is briquetted and stored loose in bags. The use of the proposed method of preserving feed provides, in comparison with the known, an economic effect in cyNnvie rubles. per 1 ton of grass flour or briquettes. In addition, when using the proposed method, energy is saved (118 kW / h per 1 ton of production) t fuel is saved (10.4 kg per 1 ton of harvested feed); reduced time for preserving food by 20%; i improves the quality of food by 8-10%; in addition, the method is carried out by existing machines and aggregates in production. Claims method of preserving feed, including cutting feed crops, grinding green mass, drying and preserving by salting, characterized in that, in order to reduce energy consumption, improve quality and improve feed safety, the green mass is salted in front of the head at the rate of 3-3.5 kg finely ground salt per 1 ton of raw material, and drying is carried out to moisture. 22-25% with the subsequent preparation of briquettes or laying in storage and scattered form.
