Pets have become a part of many people's daily lives, and how to feed their pets well has become the most talked about topic among owners. The quality of pet feed directly affects the growth of pets. Nowadays, more and more people are considering purchasing pet feed with nutritional value. About 95% of the nutrition of American pets comes from pet feed, mainly divided into dry food, wet food, and snacks. The production in 2009 has reached 8.01 million tons, with dry grains accounting for about 82%. These dry grains need to be dried, and obtaining high-quality dry grains requires high-quality drying equipment.

The intelligent static microwave vacuum drying equipment adopts advanced microwave energy and vacuum low-temperature drying technology. Through intelligent control, gelatin is quickly dried in a low-temperature state. This low-temperature rapid drying method has high product quality, low production cost, simple production process, energy saving and environmental protection.

The WBZ series intelligent static microwave vacuum drying equipment is a comprehensive high-tech drying equipment that combines microwave energy application technology with vacuum drying technology. It solves the global problem of uniform drying of materials in a static state. The equipment has high safety and stability, and is a patented technology of our company. It has the characteristics of low drying temperature, high quality, short time, high efficiency, high yield, and low cost. It is a high-quality, fast low-temperature drying equipment.

The evaporation temperature of water during the drying process of materials is directly related to atmospheric pressure. The lower the atmospheric pressure, the lower the boiling point of water. At one atmosphere, the boiling temperature of water is 100 ℃. When the vacuum degree is less than -0.08MPA, the boiling point of water drops to 30-40 ℃. Therefore, in a vacuum state, materials can be quickly dried at lower temperatures.

Traditional heating is carried out through conduction, convection, and radiation. In a vacuum state, air convection is difficult to carry out, and only conduction can provide thermal energy to the material. External heat is difficult to enter, and internal moisture is difficult to remove. Therefore, the drying speed is slow, the efficiency is low, the cycle is long, and the temperature is difficult to control, directly affecting the drying quality of the material.

Microwave vacuum drying is the process of heating materials using microwave energy in a vacuum state. In the microwave field, the material absorbs microwave energy and generates heat as a whole. The heating speed is fast, the thermal energy distribution is uniform, the thermal energy utilization rate is high, and the moisture is quickly discharged. At the same time, the transmission of microwave energy in a vacuum state is not affected, and the material can be quickly heated by the microwave without energy loss. The material does not form a hard shell during the drying process, and the gas during drying is easily discharged. The drying temperature is low, the speed is fast, and the quality is high, and more effective ingredients can be retained.

Microwave vacuum drying is a process where materials are heated as a whole, and the drying process and quality are highly controllable, changing traditional methods. Therefore, microwave vacuum drying equipment has completely changed traditional drying technology. It not only has low-temperature, fast, and uniform drying characteristics, but also has high controllability, which can greatly improve drying quality, yield almost 100%, drying speed more than ten times faster, without reducing environmental pollution, greatly improving the economic benefits of enterprises, and becoming an advanced modern drying technology.
