All glass components are easy to disassemble and clean.
6. Equipped with an imported oil-free air compressor, the particle size of the powder sprayed follows a normal distribution, with excellent fluidity and very low noise, less than 60db, which meets the national laboratory noise standards;
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.

There is a structure similar to spray dryer, which is called spray type continuous vacuum drying device. Liquid raw materials are being added

After preheating in the heat pipe, it is sprayed into the vacuum dryer and instantly forms a porous finished product inside the dryer. The discharge is usually done using a screw push

Incoming conveyor, connected to condenser for solvent recovery. This type of dryer prototype has developed a shaping drying device, which is composed of

Invented in the United States and later developed. Mainly to avoid instant evaporation during spray drying

Raise the inlet air temperature to 80-90 degrees Celsius for the exhaust gas temperature.

It is actually a combination of spray dryer and aerated belt screen dryer. The primary dryer is high-temperature hot air

The air spray drying process is a constant belt drying stage. The second level of drying is deceleration drying. *More produced after secondary drying

The porous material is stacked on a mobile sieve and undergoes secondary drying. The key to operation is to control the moisture content to adjust its viscosity, such as

Accumulation is too tight, ventilation is poor, and secondary drying is not easy to achieve good results. It is characterized by reducing the height of the spray dryer

High thermal efficiency, suitable for materials that are sensitive to heat and difficult to dry.
