Recommended Dryer Model: ZLG Series Pharmaceutical Herbal Extract Spray Dryer

 

1. Technology Overview:

This project focuses on the spray drying project of pharmaceutical herbal extract. The high-speed centrifugal spray device of pharmaceutical herbal extract is the application of centrifugal spray drying technology in the drying of specific materials. It uses high-speed centrifugal atomizers to disperse the materials into fine, fully contact with hot air, complete the instant drying to form a powdery products. The drying equipment is specially used to solve the spray dryer of traditional pharmaceutical herbal extract and plant extract. It effectively solves many problems of the original LPG high-speed spray dryer in the drying of traditional pharmaceutical herbal extract.

2. Technology Principle:

Pharmaceutical herbal extract high-speed centrifugal spray device is the application of centrifugal spray drying technology in the drying of specific materials, and also uses high-speed centrifugal atomizer to disperse the materials into a mist, which is fully contacted with hot air to complete instant drying and form a powder Finished product drying device.

The special dryer for traditional pharmaceutical herbal extract is specially used to solve the spray drying of traditional pharmaceutical herbal extract and plant extract. It solves the following situations that occur in the drying of traditional pharmaceutical herbal extract in the original LPG high-speed spray dryer.

(1).The material sticks to the wall and the powder collection rate is low;

(2).The material stays on the wall for a long time, causing coking and deterioration of the material;

(3).It is difficult to clean and does not meet GMP requirements;

(4).Low output: LPG-150 spray dryer can only handle 50-60kg/h feed liquid.

In view of the above situation, our factory designed the pharmaceutical herbal extract dryer to solve the above problems according to the material properties and process requirements of the pharmaceutical herbal extract. The material after drying the product has good color and no deterioration, which greatly improves the product quality and also improves economic efficiency of the factory. Comparing the LPG high-speed centrifugal spray dryer, the traditional pharmaceutical herbal extract has the following characteristics:

(1).Three-stage air purification and filtration are adopted to make the air intake meet the requirements of 300,000 grades;

(2).The cold wall device is adopted to make the inner wall temperature reach 80℃, and the material stays on the wall without coking;

(3).The entire volume is 3.5 times the original LPG standard centrifugal spray;

(4).Adopt quick opening flushing device, suitable for production requirements of many varieties;

(5).The dust removal adopts wet dust removal, so that the dust does not go out, which meets the environmental protection requirements;

(6).Using air sweeping device, the effect is more satisfactory;

(7).Provide 2 atomizers and adopt frequency conversion to adjust speed;

(8).PLC control is adopted, and the screen of the program control system is displayed;

(9).Can be equipped with flushing device;

(10).It can be equipped with dry air sealed closed conveying.

3. Technology Characteristic:

(1).The tower body has a cold wind jacket;

(2).The tower body is equipped with an automatic vibration device;

(3).The tower body and pipeline are equipped with quick-open cleaning holes and drain holes;

(4).Can be equipped with automatic control constant temperature feeding tank;

(5).Can be equipped with manual high-pressure washing tower, random accessories;

(6).The parts in contact with the materials are made of stainless steel; (or all stainless steel)

(7).Material collection adopts two-stage cyclone dust collector, or one-stage cyclone dust collector and wet dust collector;

(8).Inlet air temperature realizes automatic control and continuous device;

(9).Can be equipped with air sweep device
