Shanghai * type small spray dryerProduct Description:
AS-2LThe laboratory small spray dryer is mainly applicable to the production of micro particle powder 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.

7. The atomization structure of two fluid spray, the whole machine is made of high-quality stainless steel precisely, with compact design, no auxiliary equipment, easy to use, and as new as ever.
8. 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 ℃.
9. In order to maintain the purity of the sample, an air inlet filter is equipped.
10. The feeding amount can be adjusted by the feeding peristaltic pump, and the small sample volume can reach 50ml. Magnetic stirrer is optional
11. The dried finished dry powder has a relatively uniform particle size, with over 95% of the dry powder within the same particle size range.
12. The HL-2000ML laboratory small spray dryer is equipped with a nozzle cleaner (through needle) for viscous materials. When the nozzle is blocked, it will automatically clear, and the frequency of through needle can be automatically adjusted;
13. Innovative tower wall blowing device with higher material recovery rate.

Clean the surrounding accessories

Remove the two material pipes connected to the cyclone separator, the butterfly valve at the discharge port, the collector, the clamp, and the silicone gasket, clean them all thoroughly, and then control the water to dry. When cleaning the cyclone separator, first remove the surrounding connecting accessories, and then be sure to turn off the outlet butterfly valve of the dehumidifier (to prevent water from flowing back into the dehumidifier). Align the water pipe with the inlet of the separator and flush it. Use a water basin to catch the water at the outlet to prevent it from splashing into the dehumidifier and burning out the motor. Repeat the flushing several times in multiple angles until the effluent is colorless and clear. After all the accessories are dried, install the pipeline.
