Abstract

The invention relates to a high-temperature-resistance complex enzyme coated pellet and a preparation method thereof. The pellet comprises a pellet core and a coating layer, wherein the pellet core is prepared from a solid powder enzyme preparation, starch, flour, microcrystalline cellulose and hydrogenated oil; and the coating layer is prepared from a polyacrylic resin emulsion, hydroxypropyl methyl cellulose and ethyl cellulose. The preparation method comprises the following steps of adding a carrier into the solid powder enzyme preparation and the hydrogenated oil which are uniformly mixed, and performing dry-mixing and wet-mixing to form a mixture; shaking or extruding the mixture to prepare pellets; drying and coating the pellets, and drying the pellets once again; dissolving the polyacrylic resin emulsion and the hydroxypropyl methyl cellulose in water for coating of the first layer, and dissolving the ethyl cellulose with ethanol for coating of the second layer; and conducting drying to obtain a complex enzyme coated pellet finished product. The complex enzyme coated pellet has excellent heat resistance, good stability, round appearance and uniform grain size, and has a good mixing uniformity with feeds.

Description

technical field [0001] The invention belongs to the field of post-processing of compound enzyme preparations, and in particular relates to a high-temperature-resistant coated compound enzyme pellet and a preparation method thereof.
