DESCRIPTION
1. Experimental low temperature spray dryer;
2. Solve the problem of material resurgence
3. The maximum processing capacity is 50ml/hour;
4. Inlet air temperature: 35-140 degrees (if QFN-GD series is selected, air inlet temperature: 35-220 degrees for large section drying);
5. It can be upgraded to a high and low temperature integrated spray dryer;
6. Low-temperature spray dryer and its main application in universities, research institutes and food, medicine, chemical industry, enterprises, laboratories to produce micro-particle powder, it has broad-spectrum applicability to solutions such as emulsions and suspensions, and is suitable for heat-sensitive Drying of materials such as biological products, biological pesticides, enzyme preparations, etc., because the sprayed materials are only exposed to the drying air system when they are sprayed into mist droplets, so they are only heated instantly, which can keep these active materials dry after drying. It still maintains its active ingredients from being damaged. This type of spray dryer can realize both low temperature atomization drying and high and low temperature atomization drying for spray drying at room temperature.
