Feature

■ Tower body has air cooled jacket.

■ Tower body is equipped with automatic vibration device.

■ Tower body and pipe line have cleaning hole and sewage discharge hole that can open quickly.

■ Mannal high pressure washing machine on request.

■ The parts that can contact raw material are made of stainless steel (all entirely stainless steel).

■ The collecting of raw material adopts two grades cyclone or one-grade cyclone and one-grade wet-method-deduster.

■ The temperature of inlet air can be controlled automatically and continuously.

■ Equipped with air sweeping device on request.

Descriptions

■ The machine adopts full seal from. All parts are made of stainless steel. It is equipped with three grades of filter. The filtered air is one hundred thousand grades. The cooling device of wall is installed at the cylinder body. It makes the wall temperature less than 80˚C. Air sweeping device is installed inside the drying tower. The product will not be burnt or deteriorated even stays on the way. The collection rate of powder is raised greatly. Moreover will not cause medicine mixed or wall stick.

■ Basic principle: high-speed centrifuge atomizing for the extract of traditional Chinese medicine is an application of centrifuge atomizing technique. It is an high-speed atomizing dryer. The following problems are solved.

1. Raw material is stick to the wall and the rate of powder collecting is low.

2. Because the staying time of raw material at wall is long, the phenomenon of burnt and degeneration can be produced.

3. It is difficult to clean and can not meet the requirement of GMP.

4. low in output: Model LPG-150 atomizing centrifuge dryer can process 50-60 kg/h of raw material liquid. In view of this, 

■ According to the properties and process requirements of the extract of traditional Chinese medicine, our factory researched and designed the special dryer for the extract of traditional Chinese medicine and won two items of china patent. It solves the historical difficult problems in drying the extract of  traditional Chinese medicine. 

■ The color of dried raw material is good. The dried raw material does not degenerate. It raises the economic benefit greatly. Compared to ordinary lpg high-speed atomizing dryer, it has the following features:

1. Adopted three-grade air filter, the inlet air is one hundred thousand grade.

2. Adopted wall cooling device, the temperature of inner wall will be no more than 80˚C. Even if raw material is stayed on the wall, it will not be burnt.

3. Its whole volume is 3.5 times of standard LPG high-speed atomizing dryer.

4. Adopted quick washing device, it is can meet the requirements of production for varieties if products.

5. Adopted wet-dedusting, there is no powder dust out. It is in conformity with the requirement of GMP.

6.  Adopted air sweeping device, the clean effect is satisfied.

Principle


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

■ All the hot air system, blowing system and air sending system of the drier have the first effect, middle effect and sub-high effect filters and other filters. All the air entering the drying system has passed the filtering treatment. All the sections of contacting the materials use the stainless steel and meet GMP requirements.
