METHOD FOR PREPARING RUMEN PROTECTED AMINO ACID COATED ENCAPSULATION

摘要

PURPOSE: A producing method of rumen-protecting amino acid coated with capsules is provided to perform an encapsulation process using a coating system and a cooling system serially arranged next to each other. CONSTITUTION: A producing method of rumen-protecting amino acid coated with capsules comprises the following steps: mixing amino acid with metallic soap containing vegetable fatty acid chelated with metallic ion, and fully hydrogenated oil having the melting point greater than 57 deg C; inserting the mixture into a pelletizer or an extruder, and forming particles having the size of 0.5-2.5mm to obtain firstly encapsulated amino acid; inserting the firstly encapsulated amino acid into a rotating drum type coating machine, and spraying the fully hydrogenated oil into the machine for forming a coating on the amino acid; cooling the encapsulated amino acid in the temperature lower than 40 deg C to obtain secondly encapsulated amino acid; and repeating the spraying and cooling processes on the amino acid to obtain the amino acid coated with multiple layers.
