Generally speaking, the extract contains a considerable amount of plant wax, pigment, etc. At room temperature, the extract is waxy solid, sometimes crystalline substances are precipitated, and it is not completely soluble in ethanol. With the increasing demand of traditional Chinese medicine extract, its drying problem has become complicated and a major problem in the equipment industry.

It is reported that in the past, vacuum drying equipment and microwave dryer were used to dry traditional Chinese medicine extract. Relevant experts said that these two equipments have small output and long drying time, and the products formed by drying are all cake-shaped, and they also need processes such as crushing and sieving. The process is cumbersome and requires a lot of manpower and resources.

In order to dry Chinese medicine extract better, some drying pharmaceutical equipment enterprises have improved their equipment, developed and produced centrifugal spray drier for Chinese medicine extract. It is reported that the special centrifugal spray drier has changed its technological operation and significantly reformed its main engine structure.

Before the centrifugal spray drier special for Chinese medicine extract was used, the material often adhered to the wall during the drying process of Chinese medicine extract, and the powder yield was low. The material stays on the wall for a long time, resulting in coking and deterioration of the material, and it is difficult to clean and the output is low.

Dehumidified cold air is introduced into the tower body at the lower part of the centrifugal spray drier cone, which flows reversely with the material, so that the dried hot material exchanges heat with the cold air, and the temperature of the material is reduced below the softening point of the material, thus avoiding the occurrence of material softening and stickiness. The dried materials will be discharged from the bottom of the tower, and the tail gas will be uniformly discharged around the junction of the cylinder and cone of the main tower, and a small amount of materials entrained in the tail gas will be collected and discharged by the cyclone separator.

Centrifugal spray drier also has a washing device, which is suitable for various production requirements. The wet dust removal system can keep the dust from going out, which meets the requirements of environmental protection. In addition, the equipment is equipped with a gas sweep device, and dry air can also be used for closed transportation. In addition to technology, there are also equipment companies that innovate from the perspective of structure.
