Description

The invention relates to feed production, namely the production of additives for animal feed or feed flour for feeding agricultural and non-productive animals based on brewing waste, in particular malt sprouts. The effectiveness of the feed industry is determined by solving a number of problems:

- firstly, this is the task of reducing the specific gravity of grain in animal feed;

- secondly, this is the use of new sources of feed protein in the form of new feed products, the use of which would increase the biological value of animal feed, as well as increase the efficiency of use of feed and protein by animals;

- thirdly, this is the task of rational use of secondary material resources of the food and processing industry of the agro-industrial complex of Russia, in particular brewing, the need to use these resources for feed purposes;

- fourthly, the satisfaction of increased requirements for the safety and environmental friendliness of the feed and feed used. So, currently in the world, including Russia, the production of bone and meat and bone meal for the production of dry feed has sharply decreased, since if these types of flour are used, the risk of infection of animals with viral diseases, “mad cow disease” is not completely excluded.

It is known that the brewing industry in Russia produces about 70 thousand tons of malt sprouts per year. Malt sprouts are traditionally used as a feed, cheap and are environmentally friendly, valuable, highly nutritious protein product. Malt sprouts contain soluble nitrogen-containing substances, carbohydrates, organic acids, vitamins and enzymes. The widespread use of malt sprouts is limited by the inconvenience of transportation, a relatively short shelf life due to the high hygroscopicity.

A known method of preparing feed for farm animals, in which malt sprouts are one of the components of the feed. This method involves the use of malt sprouts and involves mixing brewing waste and introducing into the enriched feed mixture an additional autolysate of brewer's yeast, table salt and feed chalk, the components being mixed in the following ratio (wt.% Per dry matter): beer grains - 82.8 malt sprouts - 7.5, grain waste - 6.0, barley alloy - 0.7, suction and polishing waste - 0.5, brewer's yeast - 0.5, protein sludge - 0.3, hop hop - 0, 2, brewer's yeast autolysate - 0.2, feed chalk - 1.0, salt p boiled - 0.3. Enriched feed mixture is replaced in the diets partially or completely feed grain, or feed, and it can be replenished with up to 50% of the missing protein (1. Pat. RF №2075298, CL A23K 1/16, publ. 03.20.1997).

The closest technical solution selected for the prototype is a composite feed for farm animals and a method for its production (2. Pat. RF No. 2086144, class A23K. 1/06, publ. 08/10/1997), which use malt sprouts as one of the components of the feed. The feed includes beer grains (1000 kg), malt sprouts (10 kg), alloy (2.6 kg), grain waste (10 kg), spent brewer's yeast (46 kg). A method of preparing feed for farm animals involves collecting beer grains, malt sprouts, alloy, grain waste, spent brewer's yeast, mixing and drying them. Heat treatment is carried out in a vacuum boiler for 1 hour to a temperature of 100 ° C and drying is carried out to a moisture content of 8 ÷ 10%.

A disadvantage of the known technical solutions is the insufficiently high nutritional value of the malt sprouts used in them due to the low bioavailability and water solubility of the nutrients contained in them. Therefore, when using well-known feeds, the nutrients of the malt sprouts are not fully absorbed by the feeding animals.

The problem solved by the claimed technical solution is to obtain feed flour from malt sprouts for agricultural and unproductive animals with increased water solubility and bioavailability of the nutrients contained in them, by mechanochemical processing of a mixture of malt sprouts with enzymes in the activator, that is, in a simpler and more economical way .

The problem is solved by the claimed method for producing fodder flour from malt sprouts for agricultural and non-productive animals and fodder flour obtained by this method.

The problem is solved thanks to the claimed method of obtaining feed flour from malt sprouts, including grinding malt sprouts into flour, in which malt sprouts are mixed with enzyme preparations with cellulolytic and proteolytic activity in a ratio of 100: 0.5-2: 0.5-2 by weight accordingly, the resulting mixture is subjected to mechanochemical treatment in an activator, and, as an activator, flowing ball vibrocentrifugal, ellipse centrifugal and roller centrifugal mills are used that provide accelerated grinding of grinding media 80 ÷ 250 m / s ² and the residence time in the treatment zone of 0.5 ÷ 2.5 min.

The problem is also solved thanks to the claimed composition obtained by the claimed method, containing malt sprouts in the form of flour, while it additionally contains an enzyme preparation having cellulolytic activity, an enzyme preparation having proteolytic activity, and has the following composition, wt.%: Enzyme preparation, possessing cellulolytic activity of 0.5-2; enzyme preparation with proteolytic activity of 0.5-2; malt sprouts - the rest.

Preferably, the total content of enzyme preparations in the inventive feed meal is 1 ÷ 3 wt.%.

Preferably, as an enzyme preparation having cellulolytic activity, the feed meal contains CelloLux-F with an activity of 2000 units / g.

Preferably, as an enzyme preparation having cellulolytic activity, the feed meal contains Cloververidin GZx with an activity of 2000 units / g.

Preferably, as an enzyme preparation having proteolytic activity, the feed meal contains Protosubtilin GZx with an activity of 70 units / g.

The indicated ratios of the concentrations of the components of the mechanochemically processed mixture and the parameters of the mechanochemical treatment (residence time in the zone of influence of grinding bodies, the number and geometric characteristics of grinding bodies loaded into the mechanochemical activator) depend on the kinetic characteristics of the mechanochemical process.

Since malt sprouts contain both cellulose and proteins, the use of enzymes separately leads to a significant decrease in the effect.

The use of enzymes in an amount of more than 2 wt.% Leads to a decrease in the economic efficiency of the use of feed flour.

The parameters of mechanochemical processing are determined by the following circumstances. When using the acceleration of grinding media less than 80 m / s ² there is a decrease in the efficiency of mixing and activation. The use of acceleration of more than 250 m / s ² leads to degradation of enzymes.

A residence time of less than 0.5 min in the processing zone does not allow to obtain a high-quality target product. A residence time of more than 2.5 minutes leads to inactivation of the enzyme preparations.

The inventive method is as follows.

Example 1

Air-dried malt sprouts are pre-crushed to a particle size of 1.0 ÷ 3.0 mm. The resulting intermediate is mixed to a homogeneous mass with enzyme preparation No. 1, having cellulolytic activity, and enzyme preparation No. 2, having proteolytic activity, in a ratio of 100: 0.5: 0.5 by weight. As enzyme preparation No. 1, CelloLux-F (activity 2000 units / g) or Cloverididin Gxx (activity 2000 units / g) is used. As enzyme preparation No. 2 Protosubtilin GZh is used (activity of 70 units / g). The resulting mixture is subjected to mechanochemical treatment in ball vibrocentrifugal, ellipse centrifugal or roller centrifugal mill, which provides acceleration of grinding media 80 ÷ 250 m / s ² and the residence time in the processing zone of 0.5 ÷ 2.5 minutes The product is a fine powder (flour) of yellow-tobacco color, with a characteristic bread-malt smell. The target product can be used as a feed in the production of animal feed and in the feeding of agricultural and unproductive (domestic) animals.

The properties of the target product were compared with the properties of the control samples. The first control sample is a semi-product after preliminary grinding to 1 ÷ 3 mm, but which has not undergone further mechanical or mechanochemical processing. The second control sample obtained by machining was prepared similarly to the target product, but without the addition of enzyme preparations and stirring.

From the data obtained it follows that as a result of the mechanical processing of the malt sprouts, the content of ROS is preserved, and as a result of the mechanochemical processing of the malt sprouts, an increase in the content of ROS is observed from 48 to 52 wt.

Example 2. It was carried out in the conditions of example 1. To further confirm the effectiveness of the proposed method at the enterprise LLC Fitolokomotiv (Novosibirsk region, Iskitim district, village Agroles) in 2009, a pilot batch was produced at a roller centrifugal mill with acceleration of 200 m / s ² feed flour from malt sprouts for agricultural and non-productive animals. Tests of the experimental batch were carried out in 2009 at the New Technologies Agricultural and Production Company LLC (Novosibirsk region, Iskitim district, Burmistrovo village) on geese of the meat direction of productivity during the fattening period. The experiment was carried out according to the following scheme: the control group of geese was fed a balanced compound feed, calculated and compiled according to zootechnical standards, with a meat and bone meal content of 3% (main diet); the experimental group of geese was fed with compound feed, in which the meat and bone meal was replaced with fodder flour from the aforementioned experimental batch. The gross increase in live weight of geese (age 55 days) from the experimental batch compared with the same indicator of geese (age 55 days) from the control batch was 8% higher.

Using the invention will allow using a new technologically simple method to obtain a feed agent from malt sprouts in the form of flour with a high content and increased bioavailability of water-soluble substances (VRV) contained in malt sprouts.

The socially useful effect of using the invention will be a more complete assimilation of the nutrients of the malt sprouts by the feeding animals with all the positive consequences arising from this, i.e. more complete and rational use of valuable, highly nutritious protein concentrate - malt sprouts.

The data obtained indicate that without mechanochemical treatment, as a result of mechanical processing of malt sprouts, the content of HRV remains at the level of 48 wt.%, While as a result of mechanochemical processing of malt sprouts, an increase in HRV is observed from 48 to 52 wt.%. This value can be interpreted as saving a valuable feed product - malt sprouts by 4% compared to the original malt sprouts or compared to malt sprouts flour obtained without mechanochemical treatment.

An additional positive effect achieved by the invention is an increase in the shelf life of fodder flour from one month established for malt sprouts by the industry standard (3. OST 18-350-79. Malt sprouts. Technical conditions), up to three months (4. STO 81124468-2009 Fodder flour from seedlings of barley "Dobrynya" (Novosibirsk, 2009). This effect is explained by the presence in the malt sprouts of grain husks containing cellulose and biogenic silicon dioxide, which, as a result of mechanochemical treatment, exhibit the properties of adsorbents - moisture absorbers and prevent rotting and mold.
