Abstract

Solid, dry basic nutritional components, for example cereal components in the form of pellets, flour, bran or flakes, dried green crops, dried potatoes or dried beet slices are mixed with liquid biologically active products - liquid cow foremilk, suspensions of water weeds, brewer's yeast and chemically preserved liquid blood, respectively with the given products thickened by boiling in a vacuum, sedimentation, filtration or centrifugation to a dry content of at least 10 % by weight, in a mass ratio corresponding to the dry matter in the mixture in a range of 60 to 70 % by weight. The thickened mixture is dried in an air flow at 35 to 45 degrees C to a final dampness in a range of 5 to 15 % by weight. Drying in the air flow can, after addition of a further share of the given liquid components and mixing 2 to 3 times, be repeated until reaching the required composition of the final product.

Description

BACKGROUND OF THE INVENTION The present invention relates to a process for the preparation of storable, free-flowing, biologically valuable feed mixtures, feed supplements and / or foodstuffs containing biologically active products using fluidized-bed drying, vacuum boiling or known separation of mechanical phase separation methods.

BACKGROUND OF THE INVENTION

Not only the main nutrients and their energy, but a number of other components such as vitamins, macro and microelements, stimulants, hormones, enzymes and the like are essential for the growth of the pups, their successful development and the optimal production of adult animals. Although many of them can now be produced synthetically and supplied to animals in this form, their physiological efficacy may not always be what we expect. In addition, disproportions between components can easily occur, especially in the case of one-sided overdose of some of them, and last but not least, the addition of these preparations in synthetic form is often costly.

A rich source of preservatives, vitamins and other stimulators are biological products such as bovine colostrum, biomass of cultivated freshwater algae, yeast, blood, blood derivatives, and the like. Their wider use is hindered by difficult conservation of these materials. It is not only the costs associated with it, but above all technological problems. In fact, conventional processes, i.e. high temperatures for dehydrating them, which destroy biological activity, in particular of protein-containing substances, cannot be used. Further possibilities are therefore being sought for the long-term storage of these valuable biological materials.

For the permanent preservation of colostrum, for example, a combined process of its chemical and physical processing has been developed, allowing all nutrients and protective components contained in colostrum contained in colostrum to be preserved (MS AO No. 268 488).

It is also possible to use freeze-drying, ie freezing of water from colostrum and other biological products. Both processes are aimed at obtaining a clean dry product which, when dissolved in water, has the properties of the original material. The disadvantage of both processes is the need for a relatively complex device and also a high energy input, which makes the resulting product very expensive.

The object of the invention was to solve a technological process of preparation of feed mixtures, feed supplements or foodstuffs, which would respect the common property of biologically active substances, ie their considerable thermolability, utilize their specific properties and lead to a new quality product with significant complex physiological effect.

SUMMARY OF THE INVENTION

The object has been achieved and the present invention provides a process for the preparation of storable, free-flowing, biologically valuable feed mixtures, feed supplements or foodstuffs containing biologically active products using fluidized-bed drying, vacuum boiling, or known mechanical phase separation techniques, A finding which consists in mixing solid, dry basic nutrient components, such as cereal components in the form of scrap, flour, bran or flakes, green fodder, dried potatoes or dried beet pulps, or other dry bulk feed mixed with liquid biologically active products, such as native cow colostrum, algae suspension, brewer's yeast or fresh blood or liquid blood derivatives, or with the aforesaid products thickened by boiling under vacuum, sedimentation or centrifugation to dry matter content, but at least 10 wt.%, in a weight ratio corresponding to the dry weight of the mixture in the range of 50 to 100 wt.%, and the resulting mixture is dried in an air stream at ntax. ° C to a final humidity in the range of 5 to 15 wt.%, Wherein the operation of drying the mixture in an air stream is repeated, after addition of a further proportion of said liquid components and mixing under said conditions, until the desired composition of the final product.

An advantage of the method of preparation of feed mixtures, linen supplements or foodstuffs according to the invention is that it allows processing and at the same time preservation of more native substances difficult to store in one technological step to produce a product with complex superadditive effect. To the extent that the product thus prepared is physiologically favorable even in small doses, the money spent on the gentle conservation process becomes more effective.

If the required concentration of the biologically active substances in the final product is not reached in the first stage of fluidized-bed drying because the water content of the mixture is too high, the feedstock suspension can be pre-thickened. Concentration is advantageous in the case of yeast by sedimentation, in algae by centrifugation and in colostrum by evaporation. Another way to solve this situation is to repeat the fluid drying process. In the first stage, only a portion of the dried liquid material is admixed to the dry feed such that the resulting mixture contains 60 to 70% by weight. dry matter and could be well fluidized. After the mixture has dried, a second portion of the suspension is added in the second phase and the drying process is resumed.

In addition to the preparation of feed supplements, the described process can be used to prepare products for human consumption. A thickened suspension of algae intended to supplement human nutrition is applied to a suitable matrix, such as oatmeal, corn flakes, various extruded products and mixtures thereof, and gently dried. Before drying, the mixture can be further enriched with other nutrients such as milk, easily digestible sugars, flavorings, or vitamins.

Examples of embodiments of the invention

Example 1

Of the 40 kg of cereal products which form the basis of the compound feed, for example for piglets (wheat meal, grated oatmeal, wheat bran), 15 kg of native colostrum is added,

2.5 kg of algae suspension with dry matter 10 Jo. and 10 kg of brewer's yeast with a dry matter content of 10% by weight. Homogenized mixture in the consistency of a wet, whitish structure with a dry matter content of 65% by weight. The mixture is fluidized in a fluid stream at 45 ° C to a moisture content of 15 wt. The resulting mixture is dosed by means of a granulator into a drying chamber in which the granulate is dried to a final moisture content of 5% by weight. The granulated product is used in weaning, diarrhea, stressful situations, either as a feed or as a supplement to a commonly used compound feed.

Example 2
