DE1052220B - Process for the production of feed or nutrients, especially for calves - Google Patents

Description

GERMAN

The invention relates to a method for producing feed or nutrients, in particular for calves, made from skimmed milk, flour and minerals.

In the production of easily digestible nutrients for calves occur in the presence of casein Difficulties in the digestibility of casein, which normally curdles in large flakes on. In the known manufacturing processes, the composition of flour types is also very different assumed the gelatinization of the starch by heating to a fairly high level Temperature of about 75 ° C is brought about, with the result that! Certain types of starch in dextrins and even converted into sugar.

In contrast, according to the invention, part of the skimmed milk is heated to about 60 ° C, while the other, unheated part of the milk to avoid clumping in the cold milk was one, two or more types of flour, such as corn starch, potato flour, calf rearing flour, wheat extract flour, Cassava flour and minerals are added and the mixture becomes homogeneous Paste is processed, which is added to the warm milk, whereupon the resulting mixture some Stirred continuously for minutes, then cooled to about 25 ° C and the resulting mixture finally, for example is dried with the aid of an atomization device.

The types of flour and the temperature of the milk are chosen so that a moderate gelatinization takes place so that the cleavage of all starch granules present is achieved. Because the partial gelatinization takes place with the help of skimmed milk, this splitting and the simultaneous stirring cause a Dispersion of the casein of the skimmed milk into the interior of the starch granules. This intimate mixture of the dispersed casein and the split starch granules has the consequence that the casein, which is suitable for young Calf is normally difficult to digest, is present in a much lower concentration so that the Effect of the Verdatrangjuices on this dispersed casein is much stronger and the digestion as a result is facilitated.

Further features and details of the method according to the invention emerge from the following Examples.

example 1

In a first step, the following substances in 2000 l of skimmed cold milk become homogeneous Mixed paste:

100 kg corn starch, 100 kg potato flour, 100 kg

Calf rearing meal, 100 kg wheat extract and 20 kg dicalcium phosphate.

The dicalcium phosphate is used to correct the mineral balance of the whole.

In a second step, 5000 l of skimmed milk are heated to around 60 ° C and this is the Paste made with the cold milk is added. The mixture thus obtained becomes a few minutes Stirred continuously for a long time at 60 to 65 ° C in order to bring about partial gelatinization. It should be noted that that at the temperature of 60 ° C, very vigorous stirring is not required, which is a reduction the operating costs of the process.

In a third step, the gelatinization is carried out by cooling the product to around 25 ° C brought to a standstill. In this way, too much hydrolysis, which leads to too much, is avoided would lead to severe degradation of the feed.

Finally, in a fourth operation, the mixture is dried by spraying, preferably in a very high speed of z. B. 12,000 rpm rotating turbine device. Drying is carried out in hot air at temperatures of about 140 to 150 ° C In this way a product can be obtained, the IOO ⁰ Aag is digested and completely sterile.

According to this example, 950 kg of feed are obtained, which preferably contains 7% of an additional nutrient

means that, in addition to the minerals, such as magnesium and calcium salts, contains the vitamins necessary for the assimilation of the minerals, the proportion of magnesium and calcium salts being such that the nutrient mixture absorbed, i.e. the main nutrient and the additional nutrient, has a CaO + MgO content of 37 to 39 milliequivalents and contains at least twice the amount of CaO + MgO in relation to the K ₂ O in milliequivalents. The nutrient obtained in the manner described is particularly suitable for rearing and for Fattening calves. Example 2 Cassava flour can also be added to the nutrient. In this case the flour mixture contains 80 kg corn starch, 80 kg potato flour, 80 kg calf rearing meal, 80 kg wheat flour and 80 kg Cassava flour, with the rest of the other ingredients and operations being the same as in Example 1. Patent claims: \. Process for the production of fodder or ^: nutrients, especially for calves, from skimmed milk, flour and minerals, characterized in that part of the skimmed milk is heated to about 60 ° C, while the other, unheated part of the milk is avoided from the formation of lumps in the cold state one, two or more types of flour, such as corn starch, potato flour, veal rearing meal, Wheat extract flour, cassava flour and minerals are added and the mixture becomes one homogeneous paste is processed, which is added to the warm milk, whereupon the resulting mixture Stirred continuously for a few minutes, then cooled to about 25 ° C and the obtained Finally, the mixture is dried, for example with the aid of an atomization device. 2. The method according to claim 1, characterized in that the skimmed milk is about 10% by weight a mixture of the types of flour and about 0.5 percent by weight of dicalcium phosphate will. 3. A process for the production of additional nutrients to the main nutrient prepared according to claims 1 and 2, characterized in that magnesium and calcium salts and the vitamins necessary for the assimilation of the minerals are mixed in, the proportion of magnesium and calcium salts being measured so that the nutrient mixture absorbed, ie the main nutrient and the additional nutrient, has a CaO + MgO content of 37 to 39 milliequivalents and contains at least twice the amount of CaO + MgO in relation to the K ₂ O in miliequivalents.
