Working Principle and Characteristics of Chinese Medicine Extract Spray Dryer

Abstract:
Chinese medicine extract spray dryer working principle: air through the primary, middle and high three filters and heating device filtration, heating, into the drying room at the top of the hot air distributor, through the hot air distributor of the hot air in a spiral uniformly into the drying room, the preparation of the material liquid at the same time by the pump to the centrifugal atomization nozzle mounted on the top of the drying room, the material liquid is sprayed into a very small atomized droplets, so that the material liquid and the hot air connected to the……. …

Chinese medicine extract spray dryer working principle:
  The air is filtered and heated through the primary, middle and high level three filters and heating device, and enters into the hot air distributor on the top of the drying room, and the hot air through the hot air distributor enters into the drying room uniformly in a spiral shape, and the prepared material liquid is sent to the centrifugal atomizing nozzle mounted on the top of the drying room at the same time by the pump, and the material liquid is sprayed into very small atomized droplets, which makes the material liquid and the hot air contact the specific surface area increase greatly. Small droplets and hot air mixed and flow downward sinking, instantaneous heat exchange, the moisture in the liquid is heated and quickly evaporated, in a very short time the liquid is dried into particles of products, under the action of wind and gravity at the bottom of the tower and the cyclone separator trap, the exhaust gas is purified by the dust removal and then discharged to the outside world.

Chinese medicine extract spray dryer features:

1. In order to prevent the material section from sticking to the wall, the equipment is equipped with air sweeping wall, tower wall jacket cooling structure, effectively preventing the product from sticking to the wall coking. Improve product quality and yield.

2. Special air conveying system for finished products, which separates the dried products from the hot and humid air in the system in time, and avoids the possibility of moisture-absorbing and caking of finished products.

3. The air entering the dryer adopts three-stage air purification.

4. Adopting quick-opening flushing selection device, suitable for multi-species production requirements.

5. The material collection adopts two-stage cyclone dust removal device or one-stage cyclone dust removal + wet dust collector.

6. the volume and configuration of the spraying tower are adjusted according to the nature of the material to make it more practical.
