Licorice (scientific name :Glycyrrhiza uralensis Fisch) alias: national old, sweet grass, Urallicorice, sweet root. Legumes, licorice genus perennial herbs, roots and rhizomes stout, is a tonic Chinese herbal medicine. A very good medicine for the human body, medicinal parts are roots and rhizomes, medicinal roots are cylindrical, 25~100 cm long, 0.6~3.5 cm in diameter. The skin varies in tightness and the surface is reddish brown or grayish brown. The rhizomes are cylindrical, with bud marks on the surface and pith in the middle of the cross section. The air is slight, the taste is sweet and special. Its functions include clearing heat and detoxification, expelling phlegm and relieving cough, abdominal cavity and so on. A dry climate with long sunshine and low temperature. Licorice grows in arid and semi-arid desert steppe, desert edge and loess hilly area. The roots and rhizomes are used for medicinal purposes.

Licorice is a commonly used bulk medicinal material, both medicinal and edible varieties, with an annual demand of about 60,000 tons, ranking in the forefront of various medicines. In recent years, the production and sales of home-grown licorice have increased, and the market is more popular than wild products. Licorice national medicine old, has the reputation of "ten prescriptions and nine grasses", is widely used in clinical formulations, at the same time, licorice extract is widely used in industrial, chemical and other fields, and has a large number of exports. The number of licorice is huge, the market is not strong, with the increase in the market share of household products, attention is obviously increasing.

This machine uses a high-speed centrifugal atomizer to disperse the material into a mist, and fully contact with the hot air to complete the instant drying, forming a powder finished product drying device. The air first passes through the primary and medium effect filter, is heated by the heater and then enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape evenly, and the hot air and flow contact can be dried into finished products in a very short time. The finished product is continuously output from the bottom of the high efficiency cyclone separator, and the exhaust gas is discharged by the induced draft fan.

(1) The drying speed is very rapid, after the material liquid is sprayed, the surface area increases, and in the high temperature air flow, most of the water can be evaporated instantly, and the drying time is generally only about 5-40S.

(2) The temperature of the droplet during the drying process is not high, and the product quality is good. Temperature range for spray drying. Even if the high temperature hot air is used, the exhaust air temperature is not very high, and the material temperature does not exceed the wet bulb temperature of the surrounding hot air in the early drying stage, which is especially suitable for heat-sensitive materials.

(3) The product has good dispersion, fluidity and solubility. Since the drying process is completed in the air, the product remains in the natural ball similar to the liquid drop, with good fluidity.

(4) The production process is simplified and the operation control is convenient. Spray is usually used to deal with the wet content of 40%-90% of the solution, can be dried into powder products, most of the products do not need to be crushed and screened after drying, thus reducing the production process, simplifying the production process. The particle size, loose density and moisture of the product can be adjusted by changing the operating conditions, and the control is more convenient.
