Detailed description

The machine adopts fully enclosed form, all parts are made of stainless steel, equipped with three-stage purification device, the filtered air reaches 100000 level requirements. The cold wall device is installed on the cylinder body and the top, so that the wall temperature is less than 80 ℃, and the material does not coking on the wall, which greatly increases the powder collection rate (more than 95%), and does not produce the phenomenon of mixing and sticking to the wall.

Basic principle:

The high speed centrifugal spray device of Chinese medicine extract is the application of centrifugal spray drying technology in the drying of specific materials. It is also a drying device that uses high-speed centrifugal atomizer to disperse the material into fog and fully contact with hot air so as to finish instant drying and form powdery finished products.

The Chinese medicine extract dryer is a spray dryer specially designed to solve the problem of Chinese medicine extract and plant extract. It solves the following problems in the drying process of the traditional LPG high speed spray dryer in Chinese medicine extract.

1. The material adheres to the wall and the powder collecting rate is low;

2. The material stays on the wall for a long time, resulting in 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, its output can only deal with 50-60Kg/h liquid.

In view of the above conditions, according to the material properties and technological requirements of Chinese medicine extract, our factory has designed a difficult problem of Chinese medicine extract dryer. After drying, the color of the material is good and not deteriorated, which greatly improves the economic efficiency of the factory. Compared with the LPG high-speed centrifugal spray dryer, the Chinese medicine extract has the following characteristics:

1. Three stage air purification is adopted to make the air inlet reach 100000 level;

2. The cold wall device is used to make the temperature of the inner wall reach 80 ℃, and the materials will not coking when staying on the wall;

3. the entire volume is 3.5 times the original LPG standard centrifugal spray.

4. Quick opening flushing device is adopted, which is suitable for various production requirements

5. Wet dedusting is adopted to keep the dust from going out and meet the requirements;

6. The effect is more satisfactory by using air sweeping device;

7. The atomizer adopts frequency conversion speed regulation.

8. PLG control and program control system screen display are adopted;

9. It can be equipped with flushing device;

10. Dry air can be used for airtight transportation.

Technical parameters:

Note: some parameters are adjusted according to different materials, and the design shall prevail.
