RU2245629C1 - Method for preparing fodder supplement based upon post-alcoholic distillery grains and soybean - Google Patents

Abstract

FIELD: fodder production.

SUBSTANCE: the present innovation deals with preparing fodders out of waste products of alcoholic production. The method deals with filtration of distillery grains followed by its mixing with soybean grinding product, chalk, salt. Then comes drying, fragmentation and granulation.

Description

The invention relates to the alcohol industry, namely the preparation of feed from waste from alcohol production.

Known methods of feeding post-alcohol distillery stillage in various forms: fresh and warm, canned and silage, mixed with straw, straw, chaff, oatmeal, bran and other feed additives. Prepare fodder lanes, enriched distillery concentrate (OBK) and dried distillery vodka for feed from post-alcohol stillage.

Before feeding the animals, the soybeans are subjected to heat treatment, extrusion, infrared, ultraviolet and microwave (VHF) irradiation and other methods for inactivating the anti-nutritional substances contained therein (Combine feed, 2002, No. 6, pp. 25-26).

All types of heat treatment of soybeans require significant energy costs.

Reducing energy costs for the heat treatment of soybeans, utilization of vinasse and the production of feed additives for farm animals on the basis of vinasse and soybeans is achieved by filtering the vinasse into the mixer, in which it is mixed with soybean grinding, salt and chalk, then dried at a temperature of 130- 140 ⁰ to the content of CB = 90-92% and carry out crushing to a homogeneous mass, add vitamins and minerals and granulate.

The drawing shows a process diagram of the installation for implementing the proposed method. The post-alcohol distillery vinasse with a content of CB = 6-8% of the volume by centrifugal pump 1 is pumped from the distillery pit 2 to the vinasse collector 3. From the vat-collector 3 vinasse is directed by gravity to the screw filter press 4. From the filter press 4 the vinasse filtrate to 50 % of volume with a concentration of CB = 2–3% is directed by gravity to the stillage 5 filtrate collector and subsequently pumped to the technological needs of alcohol production by a centrifugal pump: to sort the grinding of starch-containing raw materials and to dilute the mash. The remaining stillage with a content of CB = 25-30% by screw conveyor 6 is directed to the second filter press 7. From the filter press 7, the filtrate of the stillage CB = 3% by gravity enters the collector of the stillage of the stillage 8 and is sent to the evaporator by centrifugal pump 9. the content of CB = 35-40% from the filter press 7 is sent to the mixer 11, soybean grind up to 40% to the volume of stillage, chalk, salt, condensate from the evaporator 12 and gravity from the evaporation unit 10, the distillery concentrate CB = 40- fifty%. In the shirt of the dryer 13 fall steam under a pressure of 5-6 atm. The temperature in the dryer is maintained at 130-140 ⁰ C. From the rotary-disk dryer, the feed mixture with a content of CB = 90-92% enters the hammer mill 14, the evaporated moisture of the feed mixture from the dryer is sent to the evaporator 12.

The grinding coming out of the hammer mill 14 is transferred by a screw conveyor 15 to a mixer 16, where it is mixed with mineral additives and vitamins supplied to a mixer 16 from the collectors 17 and 18. The mixed fodder mass is fed by a screw conveyor 19 to the granulator 20. From the granulator, the feed is ready to be fed. additive packaged in bags and sent for sale.

Example 1. Mix 400 ml of potato stillage with a content of CB = 45% of the volume with 50 mg of soybean grinding with a content of CB = 14% of the volume. Drying the mixture is carried out at a temperature of 120 ⁰ C for 10 minutes To determine the activity of urease pH, a 50 mg sample of soybean grinding is taken, not mixed with vinasse, and here it is subjected to heat treatment in the same mode as the mixture. A chemical analysis of the mixture is carried out after drying and heat treatment, and unmixed soybean grinding is checked for urease activity.

In the table. 1 shows the chemical composition of the mixture (potato stillage and soybean grinding) and the activity of pH urease in soybean grinding.

Example 2. Mix 400 ml of potato stillage with a content of CB = 45% of the volume with 50 mg of soybean grinding with a content of CB = 14% of the volume. The mixture is dried at a temperature of 130 ⁰ C for 5 minutes.

The activity of pH urease in soybean grinding is produced similarly to the first example.

In the table. 2 shows the chemical composition of the mixture (potato stillage soybean milling) and the activity of urease pH in soybean milling.

Thus, the advantage of the proposed production line over the prototypes is as follows: obtaining a feed additive with a high protein content (27-40% in a.u. of a.e.) as a result of inclusion of soybean grinding in the stillage; the use of heat supplied for drying bards to inactivate anti-nutritional substances contained in soy, while there is no need to mount thermal units on farms to inactivate anti-nutritional substances in soy when preparing it for feeding to farm animals; disposal of bards. The proposed method has the following technical and economic advantages over prototypes. The protein content in the feed increases by 8-10% due to the inclusion of soybean grinding in the mixture. With the capacity of the distillery 1000 dal alcohol per day, 70-80 kW of electric energy is saved on the inactivation of anti-nutritional substances contained in soybean grinding, using heat directed to drying the stillage. About 30 tons per day of a high-protein feed additive for farm animals are obtained from the currently unused alcoholic waste.
