Pet feed is an important part of pets' daily diet. The sterilization process during its production and processing is crucial to ensuring pet health. So what are the common pet feed sterilization methods?

1. High temperature sterilization: Kill microorganisms by heating to achieve antiseptic and hygienic purposes. However, since pet feed contains a lot of nutrients such as protein and fat, heating treatment can easily lead to the loss of nutrients in the dry food and also reduce the taste and color of the dry food.

2. Ultraviolet sterilization: Kill microorganisms by irradiating ultraviolet light. However, due to the different shapes and sizes of pet feed, it is difficult to ensure full coverage of ultraviolet irradiation, so the sterilization effect is often not ideal.

3. Microwave sterilization: The action of microwaves causes the water and ions in the microorganisms to vibrate and generate heat, thereby achieving the purpose of killing microorganisms. Compared with traditional sterilization methods, microwave sterilization has the advantages of high efficiency, energy saving, and environmental protection.

Why are microwave sterilization equipment used now?

1. Rapid sterilization: Microwaves can quickly heat the inside of pet food to achieve rapid and uniform sterilization, greatly shortening the production cycle.

2. Energy efficiency: Microwave heating is a method of efficient energy utilization. Compared with traditional heat treatment methods, microwave heating can better concentrate energy and reduce energy waste.

3. Maintain product quality: Microwave heating has less impact on food and can better maintain the nutritional content and taste of pet feed.

4. Strong controllability: Microwave equipment has strong controllability. Producers can adjust the microwave heating parameters as needed to achieve better sterilization effects.

Generally speaking, microwave sterilization equipment is widely used in pet dry food production because of its high efficiency, energy saving and good maintenance of product quality.
