ZLG spray Dryer for Traditional Chinese Medicine Extract

overview
■ The special spray dryer for traditional Chinese medicine extracts is a drying machine developed by absorbing foreign technology and suitable for traditional Chinese medicine products with low melting point and high sugar content, and has the characteristics of non sticking to the wall and not easy to absorb moisture. The device determines the technological conditions of spray drying according to the characteristics and properties of the dried products. It is highly automated, easy to operate, and meets GMP requirements. The calculation and determination of technological parameters are all completed by computers. The successful development of this device has determined the technical difficulties that many Chinese medicine products with low melting point and high sugar content cannot be dried by spray over the years, and it is also a new development of the research on the application technology of spray drying in the Chinese medicine pharmaceutical industry.
characteristic
The drying speed is fast, usually only taking a few seconds, with the characteristic of instant drying.
The temperature of the droplets during the drying process is relatively low, which is particularly suitable for drying thermosensitive materials and can maintain the color, aroma, and taste of the materials.
To prevent wall sticking in the drying tower, this device is equipped with a special structure to effectively eliminate the phenomenon of product wall sticking.
The finished product air delivery system separates the dried product from the hot and humid air inside the system in a timely manner, avoiding the possibility of moisture absorption or agglomeration of the dried product.
principle
After being heated by the heater, the air enters the hot air distributor in the drying tower through the blower. After passing through the hot air distributor, the hot air uniformly enters the drying tower and moves in a spiral shape. At the same time, the feed pump sends the feed liquid to the centrifugal spray at the drying tower, and the feed liquid is sprayed into small mist droplets. The surface area of the material liquid in contact with hot air is greatly increased, and the moisture evaporates rapidly, drying it into a dry product in a short period of time. Dry products are separated from humid air by a cyclone separator, and the dry air is sent to a small cyclone separator for separation through the aggregate cyclone chamber at the bottom of the cyclone separator, and collected in the material cylinder. The exhaust gas is discharged through a induced draft fan.
The hot air system, blowing system, and air delivery system of the dryer are all equipped with primary, medium, and sub grade filters. All air entering the drying system is filtered, and all parts in contact with the material are made of stainless steel, which meets GMP requirements.
