Overview

Laboratory low temperature vacuum spray dryer manufacturers are mainly applicable to the production of micro particle powders in universities, research institutes and laboratories of food, medicine and chemical enterprises. It has broad spectrum applicability to all solutions such as emulsion and suspension, and is suitable for the drying of heat sensitive substances such as biological products, biological pesticides, enzyme preparations, etc. Because the sprayed materials are subject to high temperature only when sprayed into aerosol particles, they are only heated instantaneously, which can keep the active ingredients of these active materials intact after drying.

Laboratory vacuum spray dryer Low temperature spray drying of traditional Chinese medicine is a process widely used in liquid process forming and drying industries. It is suitable for generating powder, granular or blocky solid products from solutions, lotion, suspensions and plastic paste liquid raw materials. Centrifugal spray dryer can dry solutions, lotion, suspensions and paste materials into dry powder while maintaining its active ingredients.

BA-PWGZ2000 laboratory vacuum spray dryer is elaborately developed for heat sensitive materials. The whole machine is compact in design and can operate without other facilities. One click power on, color large LCD touch screen operation, can adopt automatic or manual monitoring two operation modes, convenient for operation and monitoring of the experimental process, especially achieving instant drying of materials under low temperature conditions (50 ℃), providing an extremely convenient and safe drying method for heat sensitive materials, such as enzyme preparations, active bacteria and other biological products, high sugar content extracts of traditional Chinese medicine natural products, heat-resistant polymer materials, materials that vaporize when exposed to heat, etc.

Small spray drying tower

2. Color touch screen operation: PID constant temperature control for heating temperature, and the feeding speed of the peristaltic pump can be adjusted at any time.

3. Equipped with an oil-free air compressor, the particle size of the powder sprayed follows a normal distribution, with excellent fluidity and very low noise, meeting the national laboratory noise standards;
4. The spray head is a concentric spray head. During atomization, ensure that there is no eccentricity that causes the spray to one side of the bottle wall. The spray head can move up and down after installation to facilitate the adjustment of the atomization position and improve the drying effect of spray; The atomization structure of the two fluid spray is precisely made of stainless steel materials. It is compact in design, no accessory equipment is required, and it is convenient to use, as new as ever.
5. In order to meet the requirements of users to adjust various parameters within the experimental range, real-time PID constant temperature control technology is adopted in the design of drying temperature control, which ensures accurate temperature control in the entire temperature range and a heating temperature control accuracy of ± 1 ℃.
6. The feed rate can be adjusted by the feed peristaltic pump, with a rated processing capacity of 800mL/H

3. Equipped with a nozzle cleaner (through needle), it will automatically clear when the nozzle is blocked, and the frequency of through needle can be automatically adjusted;

4. Rated material handling capacity: 1500mL/H;
5. Sample size: 50mL (depending on the difference in solid content of the material);

6. Real time PID constant temperature control technology, heating and temperature control accuracy: ± 1 ℃;

7. Nozzle caliber: 0.5mm, 0.7mm, 1mm, 1.5mm, 2mm optional, and can be customized according to customer requirements;

8. Whole machine power: 6KW/380V;

9. Instantaneous spray drying is completed at low temperature (50~80 ℃). Under this drying condition, the easily oxidized, volatile and heat sensitive substances can well maintain their chemical structure and biological activity;

10. Vacuum degree -0.05-0.06MPA;

11. Color LCD touch screen operation control, fully Chinese operation interface.

(1) The feeding speed of the material is too fast and the amount is too large, which makes it impossible to dry. The solution is to slow down the feeding speed and quantity, and adjust the feeding pump appropriately.

(2) The operation was not carried out according to the instructions, and the main tower was not heated. The solution is to increase the inlet temperature of the dryer.

Fault 2: There are a large number of impurities in the product

Reason and solution:

(1) The materials of the spray dryer contain impurities, which are not filtered out during filtering. The solution is to check the air filter and replace the filter screen according to the situation.

(2) The purity of the material liquid is not high. The solution is to sample and test the material liquid to filter out impurities.

(3) There are impurities in the device memory. The solution is to regularly clean the device comprehensively to remove impurities.

Fault 3: Severe powder loss and low product recovery rate

Reason and solution:

(1) The solution to the problem with the cyclone separator is to inspect it for any gaps and ensure its airtightness is intact.

(2) The dust removal performance is low, and the solution is to increase the secondary dust removal appropriately.
