Abstract

FIELD OF THE INVENTION The invention relates to a feed mill industry, in particular to the production of granulated animal feed. The aim of the invention is to increase the strength of the granules and increase their quality. Calcium chloride or ferric chloride is dissolved in water and sodium hydroxide solution is added. Then, xylitol production waste from wood is introduced in the form of an aqueous solution containing 80% solids, including 44% xylitol, 11% sorbitol, 17% arabitol, 4% dulcite and 3% mannitol. The resulting binder solution with a solids content of 20-30 wt.% Is introduced into the feed during granulation in an amount of 3-5% by weight of the granulated mixture. As a result, the strength of the granules increases (their crumbiness decreases) in comparison with the prototype by 6.9%, and the quality of the granules also increases due to a decrease in their uncertainty. 1 hp f-ly, 1 tab.

Lm ime R 1. In 74.76 incl. water dissolve 0.14 wt. calcium chloride and introduced into the solution of 0.1 ppm. sodium hydroxide. To the mixture was added 25 cw. xylitol production waste from wood in the form of an aqueous solution containing 80% solids, incl. %: xylitol 44; sorbitol 11; arab 17; dulcite 4; mannitol 3, until calcium hydroxide is completely dissolved. The resulting solution, containing 20% by weight of dry substances, 0.05% by weight of calcium, and 0.055% by weight of sodium, is introduced into the compound feed during granulation in an amount of 3% by weight of the mixture being granulated,

Example 0. A binder is prepared analogously to example 2, the resulting solution is used analogously to example 9.

The effectiveness of the proposed method of pelletizing the feed was evaluated by changing the strength of the granules in terms of crushability and sanitary state.

in terms of conditional contamination, attributed to that of the prototype, taken over 100%.

The results of the experiments in comparison with the prototype are given in the table.

It follows from the table that when the proposed method is carried out, the strength is significantly increased by 6.9% and the sanitary condition of the granulated feed improves as compared with the prototype. AT

If a binder containing less than 20% solids and less than 0.05 wt.% metal is used, and the binder is added less than 3%, the quality indicators of the granules are improved.

slightly compared with the prototype, which makes it economically impractical to use a new binder.

. An increase in the mass fraction of dry substances in the proposed binder over 30% increases its viscosity and makes it necessary to preheat the liquid additive prior to its introduction into the feed. With the introduction of the proposed

The amount of moisture in the compressed feed during granulation in an amount of more than 5% by weight of feed increases the humidity of the compression mixture and increases the cost of preparing pellets. In the case of

binder containing more than 0.10 wt.% of metal ions, its share in the feed will exceed the permissible norms for the content of trace elements on feed rations.
