Description

one

This invention relates to the production of feed from beet sugar production and glutamic acid.

The use of reed and saek-5. Molasses molasses as animal feed is known. Due to the high caloric content of these products, their use in feed has increased steadily. However, the syrup is in a liquid, and therefore it is difficult to process.

When it is introduced into foodstuffs or into carriers, for example palmmeal cake, bran, straw, peat, is, it has to be reheated. In addition, the molasses contains very little nitrogen, phosphorus, and calcium and does not meet the protein requirements of farm animals, therefore it is recommended to mix molasses with various salts containing phosphorus, calcium, and nitrogen when preparing food.

A method of producing animal feed is known, comprising mixing a liquid phase containing 20-70% pat-ox (molasses) and 8-20 urea with a solid phase containing phosphorus salts and calcium, for example calcium chloride, ammonium polyphosphates, tripolyphosphate. one.

However, the feed composition obtained in a known manner is of poor quality; in addition, it is obtained in liquid form, which makes its use difficult.

The purpose of the invention is to improve the quality of the feed product, to bring the content of Ca / P, N / P and Ca / M to a level that corresponds to the consumption of the animal.

The goal is achieved by the fact that in the method of obtaining food, including mixing a liquid phase containing molasses, and a solid phase containing phosphorus salts and calcium, the solid and liquid phases are mixed in

cc ratio is 0, and monovine phosphate and calcium oxide are used as the solid phase by weight ratio Ca / P 0 ,. N / P 0.9: 1.70 oe as a liquid phase — additionally waste products from the production of fruit juices and glutamic acid or their mixture with molasses, and the resulting mixture is dried.

Moreover, in order to increase the Ca / P, N / P content and to the level of the animal's needs, nitrogen-containing or ammonia-containing salts, or carbonate, or calcium sulfate, or dolomite, or magnesia are added to the mixture.

The weight ratio between the solid and liquid phases is preferably .0.96: 1.12.

Feed composition is obtained in eide powder, granules, tablets or some extruded product

The main raw materials for feed preparation are sugar production wastes, such as beet or cane syrup, urea phosphate and hydrated lime. In addition, you can use other industrial waste containing sugar, such as waste production of fruit juices and glutamic acid.

The chemical composition of the molasses is very diverse and depends on their origin. The molasses suitable for use according to the invention have the following characteristics: humidity 20-25, total sugar expressed in sucrose protein raw materials (6.25): 2-10 all mineral materials 6-12.

Sugar-containing industrial waste from the production of glutamic acid has additional advantages, since they contain about 39 raw proteins.

The carbohydrate content in the waste products of glutamic acid is 8-E%, the content of citrus syrup is about C6%.

The solid phase is formed mainly o6 ia3OM from a mixture of phosphate and calcium, introduced in the form of hydrated lime. Weight ratio of Ca / P 0.68 / 2.40 gO, 68 / 1.80, N / P 0.90 / 2.70 g

0.90 / 1.75.

Urea phosphate is a white solid obtained by crystallization.

mixtures of phosphoric acid and urea in stoichiometric proportion.

Thus, urea phosphate, passing for the composition according to the invention, 5 titrates, and 17.3-17.5% urea nitrogen.

The recommended granule size is 100% passage through a sieve with openings of 0.630 mm.

0 Made a feed product with the content of Ca (OH) o. and having a 100% pass through a 0.05 mm sieve.

It is established that with the introduction

5 parts of calcium in the form of carbonate during the neutralization reaction are emitted with CO2, which contributes to a more sprayed product by the end of the operation.

0 As minor constituents, nitrogen and ammonium salts, calcium carbonate or sulphate, dolomite or magnesia can be included to adjust the weight

5 ratios of calcium, (phosphorus and nitrogen) phosphorus, as well as the weight ratios of calcium and magnesium with other substances, taking into account the purpose of the feed.

Additional ingredients include, for example, alfalfa flour, oil cakes, etc., oligo preservative agents (for example, phosphoric acid) and, finally, inert fillers.

When implementing the proposed method, the weighed quantities of various products included in the composition

j lay in the mixer of the classical type. During the operation, calcium phosphate is formed and the temperature rises. The viscosity of molasses is reduced, which facilitates the production of a homogeneous mixture. On leaving the mixer, the mixture is directed to the dryer. All types of dryers used in particular in the food industry or the fat industry, for example rotary dryers, dish-dryers and hot air flow dryers, are suitable for this. Drying can also be done in the mixer itself, if it is equipped with the necessary device. In some cases, exothermicity associated with blending can eliminate drying. If the composition is intended for release in powder, it is crushed and sieved prior to packaging. To give the mixture the form of granules or sticks, it is molded directly upon leaving the mixer. The same machine can be used for mixing and shaping.

When treacle has an increased moisture content (above the norm by approximately 25%), it is useful to introduce the fines of the finished product into the mixer.

Waste from the production of fruit juices and / or glutamic acid can replace all the molasses or part of the molasses. In addition, it is useful to introduce at least one portion of calcium in the form of calcium carbonate into the composition.

At various stages in the production of the feed mixture, the sugar from these wastes does not go into glucose and into fructose and remains in the form of sucrose. Therefore, the food products obtained according to the invention do not undergo fermentation, which can lead to significant energy losses.

The interaction of urea phosphate and lime in sugar-containing industrial waste makes it possible to obtain energy forage products rich in phosphorus and calcium, with nitrogen content equal to or approaching its content in the best cake meal.

The resulting feed products contain such essential elements as phosphorus and calcium, as well as urea nitrogen, which in ruminants is converted into protein nitrogen by gastric microorganisms, which favor the increase in energy of the carbohydrate.

The following examples illustrate the proposed method, but do not exhaust it.

Example 1.AB. In the mixer, 551 kg of beet molasses (density 1.39), 176 kg of hydrated lime with Ca (OH) 95 content, 385 kg of crystallized urea phosphate and 5 kg of palm cake are laid. The formation of a reactive viscous mixture is accompanied by an increase in temperature. The residence time in the mixer is 3-5 minutes, depending on the type of machine used.

B. The way the bookmark corresponds to paragraph A. The difference is

that the product exiting the kneader is introduced into an extrusion machine or a compacting machine to produce small sticks or granules, which then go to the dryer. The diameter of the sticks or granules is chosen depending on the presentation.

B, The method of laying the raw material corresponds to point A with the difference

That is, the product exiting the kneader is introduced into the granulator tube, where the fines are simultaneously fed for re-granulation.

The product is granulated in accordance with the VII with the accepted technique of granulation in the textile industry, then dried, cooled, sieved. A quality product is sent to the warehouse, and fines and large particles

JJ after crushing is returned to the granulator. The quality product has the form of granules with a diameter of 3 mm.
