Silkworm pupa microwave vacuum dryer

Silkworm pupae are an ideal nutritional food containing high protein, low fat, multiple vitamins, and trace elements. Silkworm pupae can be used as both food and nutritional supplements. Generally, people consume silkworm pupae through frying or steaming, which results in the loss of many nutritional values and a significant decrease in their quality.

The intelligent static microwave vacuum drying equipment adopts advanced microwave energy and vacuum low-temperature drying technology. Through intelligent control, silkworm pupae are quickly dried at low temperatures. This oil-free low-temperature rapid drying method can obtain high-quality silkworm pupae, increase storage time, and is a truly green product.

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. 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 use of microwave electromagnetic fields to heat materials in a vacuum state, with fast heating speed, uniform heat energy distribution, high heat energy utilization rate, and quick removal of moisture. At the same time, the transfer of microwave energy is not affected in a vacuum state, and the material can be quickly heated by microwaves as a whole without energy loss. The gas during drying is easily discharged, and the drying temperature is low, the speed is fast, and the quality is high.

Microwave vacuum drying is a process where the material is heated as a whole, and the drying process and quality are highly controllable. 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 the drying quality. The drying speed is more than ten times faster, without reducing environmental pollution, greatly improving the economic benefits of enterprises, and becoming an advanced modern drying technology.
