Mildew eliminating method for premix carrier

Abstract

The invention discloses a mildew eliminating method for a premix carrier, which is characterized by comprising the following steps of: (1) wetting: wetting rice hull flour serving as the premix carrier by using water to make the moisture content of the rice hull flour between 15 and 20 percent; (2) heating: heating the wetted rice hull flour at the temperature of between 80 and 130 DEG C for 10 to 50 minutes; and (3) drying: drying the heated rice hull flour by a manual drying method to make the moisture content of the rice hull flour between 5 and 8 percent. The method has the characteristics that the rice hull flour is wetted first and then heated, so the mildew eliminating effect is obvious. After the rice hull flour carrier is processed by the method, the number of moulds contained inthe carrier can be reduced to less than 100 / g, which is far lower than the national feed standard of 40,000 / g. Besides, the method also has the advantages of simple process, easy operation, less investment, continuous production, high yield and the like.

Description

technical field

[0001] The invention belongs to a treatment method for a feed premix carrier, and more precisely relates to a mold removal method for a premix carrier. Background technique

[0002] Premix is ​​the abbreviation of additive premix feed, which contains one or more trace component additives (including various trace mineral elements, various vitamins, synthetic amino acids, certain drugs, etc.). Since the ingredients of additives account for a very small proportion in the premix, most of which are calculated in mg / kg or g / kg, it is necessary to uniformly mix the additive with the diluent or carrier in a certain proportion to make an intermediate compound feed product— — Premix. Premix is ​​an important component of complete compound feed. In order to ensure the quality of the premix, there are strict regulations on the mold content of the carrier. At present, in terms of the carrier of the premix, chaff powder is widely used because of its good loading and flu...

[0019] The mildew removing method of premix carrier comprises the following steps:

[0020] 1. Wetting: use cold water to moisten the chaff powder used as the carrier of the premix, so that the water content of the chaff powder is 15%;

[0021] 2. Heating: Put the moistened chaff powder on a jacket filled with heat transfer oil for heating, the heating temperature is 80°C, and the heating time is 10 minutes;

[0022] 3, drying: dry the chaff powder after heating with an electric oven, so that the water content of the chaff powder is 5%.

[0023] The artificial drying methods include electric heating baking, fuel burning baking, or dry hot air heating, etc. in the prior art.

[0025] The mildew removing method of premix carrier comprises the following steps:

[0026] 1, wetting: use the warm water of 40-80 ℃ (preferably 70 ℃) to moisten the chaff powder used as the premix carrier, so that the water content of the chaff powder is 20%;

[0027] 2. Heating: put the moistened chaff powder on a jacket filled with high-temperature steam for heating, the heating temperature is 130°C, and the heating time is 20 minutes;

[0028] 3, drying: dry the chaff powder after heating with a fuel combustion oven, so that the water content of the chaff powder is 6.5%.

[0030] The mildew removing method of premix carrier comprises the following steps:

[0031] 1. Wetting: use water vapor to moisten the chaff powder used as the carrier of the premix, so that the water content of the chaff powder is 18%;

[0032] 2. Heating: put the wet chaff powder on a jacket filled with high-temperature steam for heating, the heating temperature is 110°C, and the heating time is 15 minutes;

[0033] 3, drying: dry the chaff powder after heating with a dry hot air heating device, so that the water content of the chaff powder is 8%.
