Siraitia grosvenorii microwave low-temperature dryer

Momordica grosvenorii is a kind of precious Chinese medicinal material. It tastes sweet and has the effect of relieving cough, moistening lung, promoting fluid and quenching thirst. Traditional drying of Siraitia grosvenorii requires several days at a temperature above 80 ℃. Most of the effective ingredients of Siraitia grosvenorii are lost. The green Siraitia grosvenorii turns dark brown, and its quality is greatly reduced.

The low-temperature drying equipment of siraitia grosvenorii adopts advanced microwave energy and vacuum low-temperature drying technology. Through intelligent control, siraitia grosvenorii can be dried rapidly at low temperature to obtain high-quality siraitia grosvenorii, while maintaining its original color, greatly improving the quality of siraitia grosvenorii and increasing its storage time. It is a truly green product.

Siraitia grosvenorii low temperature drying equipment is a comprehensive high-tech drying equipment integrating microwave energy application technology and vacuum drying technology, which has solved the worldwide problem of uniform drying of materials in static state. The equipment has high safety and stability, and is the company's proprietary technology. It has the characteristics of low drying temperature, high quality, short time, high efficiency, high yield, low cost, etc. 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. 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.

The low-temperature drying equipment of siraitia grosvenorii is heated by microwave energy under vacuum state. In the microwave field, the material absorbs microwave energy and generates heat as a whole. The heating speed is fast, the heat energy is evenly distributed, the heat energy utilization rate is high, and the water is discharged quickly. At the same time, the transmission of microwave energy under vacuum state will not be affected. The material can be heated by microwave quickly as a whole without energy loss. The gas of the material during drying is easy to be discharged. The drying temperature is low, the speed is fast, and the quality is high, so more effective ingredients can be retained.

Microwave low-temperature drying is a process where the material is heated as a whole, and the drying process and quality are highly controllable. Therefore, microwave low-temperature 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.
