Problems solved by technology

The disadvantages of this high-temperature, high-humidity, high-pressure and long-term hot air drying process are: first, it seriously damages the nutrients of the product, especially for those heat-sensitive vitamins and natural active substances, which will cause irreversible damage and weaken the nutritional value of commodity grains. The second is that the energy consumption per unit output is high, which reduces the economic benefits of the product, and the third is that it will cause the loss of flavor substances and affect the palatability of the product

Abstract

The invention provides a method for processing full-price pet food under low temperature, low humidity and low pressure, the method includes mixing raw materials containing active substances and flavor substances, and performing conditioning, granulation and drying treatments under low temperature and low humidity, wherein the temperature control Below 60°C, the water content should be controlled at about 10%. The full-price pet food produced by the cold processing process of the present invention preserves the original taste of raw materials, avoids the loss of flavor substances, has good palatability, balanced nutrition, and has higher nutritional and edible value. And the product of the present invention has a unique internal structure, allowing consumers to experience the selling points of the product more intuitively.

Description

technical field [0001] The invention belongs to the field of pet food processing, and in particular relates to a cold processing method for manufacturing full-price pet food and the full-price pet food obtained by the method. Background technique [0002] The traditional full-price pet food processing method is the wet extrusion process, which includes crushing, mixing, tempering, puffing, drying, spraying, cooling and other processes. Among them, the temperature of the tempering section is generally 80~95℃, the moisture content of the material is above 20%, and the temperature of the puffing section is as high as 120~135℃, the moisture content is about 30%, the pressure is 2.6~3.0MPa, and the drying process is also in the Drying with hot air at around 90°C for 30 minutes is complete. The disadvantages of this high-temperature, high-humidity, high-pressure and long-term hot air drying processing technology are that the damage to the nutrients of the product is serious, espe...
