Medicinal material dryer market is widely used microwave technology has broad prospects

The medicinal material dryer can be said to be a good embodiment of the microwave technology dryer in the market application. It perfectly shows the characteristics of the microwave technology, and also allows people to recognize and clearly realize the broad development prospects of microwave technology.

The traditional medicinal material drying machine is designed to use coal as fuel for combustion to generate clean hot air as a drying medium to absorb the moisture in the Chinese medicine, drain out the moist air that reaches a certain amount of moisture, and circulate back and forth to reach the moisture required by the traditional Chinese medicine. The characteristics are time-consuming, laborious, unable to fully meet the requirements for medicinal drying, and poor sterilizing properties, coupled with the use of coal as fuel to pollute the environment.

Therefore, the emergence of new process technology becomes extremely necessary. The appearance of microwave technology satisfactorily met the requirements for drying and drying medicinal herbs, and coincided with the prevailing theme of environmental protection.

The microwave medicine drying machine retains the effective drug ingredients in the Chinese herbal medicine to the utmost extent. Microwaves can also kill various molds and eggs in herbs to prevent mildew and insects from being produced during storage. All this is because: Microwave heating is to make the object to be heated itself a heating element, called the overall heating method, does not require the process of heat conduction, so it can reach uniform heating in a short time. This feature allows the material with poor heat conduction to be heated and dried in a short time, the energy utilization rate is improved, and the size of the heating furnace can also be made smaller than the conventional heating furnace.

At the same time, when the material under the microwave electromagnetic field, the overall temperature of the material rises. At this point, due to evaporation of moisture on the surface of the material, the surface temperature decreases, resulting in a high temperature gradient inside and outside, the direction of this gradient just in line with the direction of moisture evaporation.

With the continuous spread of the trend of traditional Chinese medicine in recent years, the application prospect of microwave vacuum drying technology is also full of infinite light. The level of development and production of microwave drying equipment in China should be further improved, and we must move toward automation.

Airless Spray Gun
This process occurs when paint is applied to an object through the use of an air-pressurized Spray Gun. The Sprayer Gun has a nozzle, paint basin, and air compressor. When the trigger is pressed the paint mixes with the compressed air stream and is released in a fine spray.

Types of nozzles and sprays
Due to a wide range of nozzle shapes and sizes, the consistency of the paint can be varied. The shape of the workpiece and the desired paint consistency and pattern are important factors when choosing a nozzle. The three most common nozzles are the full cone, hollow cone, and flat stream.There are two types of air-gun spraying processes. In a manual operation method the air-gun sprayer is held by a skilled operator, about 6 to 10 inches (15–25 cm) from the object, and moved back and forth over the surface, each stroke overlapping the previous to ensure a continuous coat.In an automatic process the gun head is attached to a mounting block and delivers the stream of paint from that position. The object being painted is usually placed on rollers or a turntable to ensure overall equal coverage of all sides.
