ZPG Series drying equipment

Specifications

(1) Description

drying equipment for sticky material is suitable for drying the Chinese traditional medicine products that are low in fusion point and high in the sugar contents. And the machine owns the characteristics that its products do not sticky to the walls, uneasy to absorb the moisture etc. The technological conditions for spray and drying are decided according to features and property of the products to be dried for the machine. The machine is high in automation and easy in operation. It means the GMP requirements.

(2) Applications

Heated by a heater, the air enters into the hot air distributor on top section of drying tower. After passing through hot air distributor, the hot air enters into drying tower uniformly and moves in spiral state. At the same time, the material pump sends the material liquid to centrifugal atomizer on top of drying tower. Material liquid is sprayed into very fine mist-state drops. The surface area that material liquid contacts the hot air is increased greatly. The water is evaporated very fast. In a very short time, raw materials are dried into final products. Dried final products are separated with wet air by cyclone separator. The dried final products will pass through material collection whirl room at the bottom of cyclone separator and are sent to the second small cyclone separator for separation by dried air. The final products will be collected in material collection tank. The exhausted gas will be discharged through exhaust fan.

All the hot air system, blowing system and air sending system of drier have the pre, middle filter and semi-HEPA. All the air entering drying system has passed the filtering treatment. All the contact material parts use stainless steel and meet GMP requirement.

(3) Features

With a fast drying speed, the machine only needs more than ten seconds and less than twenty seconds. It has the instant drying feature.

During the drying, the temperature of liquid drops is relatively low. This is particularly suitable for drying the heat sensitive materials so as to keep the color, smell and taste.

In order to prevent that things, like sticking to the wall, appear in the drying tower, the device is equipped with a special structure that can effectively avoid material sticking to the wall.

The special wind supply system for the final products will separate the dried products with the hot and wet air in system in time to avoid the possibility that the dried final products may absorb moisture and form the block.
