Licorice, (scientific name: Glycyrrhiza uralensis Fisch) Alias: old country, sweet grass, Ural licorice, sweet root. Legumes, licorice is a perennial herb, roots and rhizomes stout, is a herbal tonic. A good human medicine, medicinal part is the root and rhizome, root medicinal properties cylindrical, length 25 to 100 cm in diameter and 0.6 to 3.5 cm. Skin tightness, surface reddish-brown or gray-brown. Rhizome cylindrical, surface bud scar, central section of myelinated. Gas micro, sweet and special. Indications detoxification, expectorant cough, abdominal and so on. Hi dark and damp, low temperature dry climate with long sunshine. Licorice more growth in arid, semi-arid desert steppe, desert margins and loess hills. Roots and rhizomes for medicinal purposes. 

        Licorice is commonly used bulk herbs, medicine and edible varieties, the annual need of about 60,000 tons, ranking the forefront of various drugs. In recent years, home-grown liquorice production and sales growth trends, market more wild and popular. Medicine licorice old country, "10 square nine grass" reputation, it has been used extensively for clinical formulations, while licorice extract is widely industry, chemical industry, and a large number of exports. Licorice huge number of artificial market is not strong, with the increase in the market share of home-grown products, attention markedly increased. 

        This machine is a high-speed centrifugal atomization allows material dispersed into a mist, complete with hot air full access to instant dried to form a powder drying means finished. Air to go through at the beginning, in effect filters, heated by a heater into the dryer at the top of the air distributor, the hot air evenly into the spiral form the drying chamber, and contacting the heat air in a very short period of time can be dried into finished. Finished continuously from the bottom of the cyclone efficiency, exhaust gas discharged from the induced draft fan. 

(1) drying speed very quickly, after the material liquid spray, surface area increases, the high temperature gas stream, it can instantly evaporate most of the water to complete the drying time is generally only about 5-40S.

(2) during the droplet drying temperature is not high, good product quality. Spray drying the temperature range. Even with high-temperature hot air, the exhaust temperature is still not very high, the initial drying, the material does not exceed the ambient temperature of the hot air wet bulb temperature, especially for heat-sensitive materials.

(3) the product has a good dispersion, mobility and solubility. Since the drying process is performed in the air, and holding the product in the instinct approximating a spherical liquid droplets, having good flowability.

(4) the production process is simplified, easy to operate controls. Spray typically used to handle moisture content of 40% -90% of the solution can be dried into a powder product, most products do not need to be dried after crushing and screening, thereby reducing the production processes, simplifying the production process. Product size, bulk density, water content in a certain range, can be used to adjust the operating conditions change, control more convenient.
