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.

FEATURES

●Adopt P.I.D temperature control system.

●The motor reverse phase and overload protection function.

●Simple and compact structure, easy maintenance and extremely low failure rate.

●Appearance The whole machine is made of stainless steel, bright and elegant.

●Color*LCD touch screen parameter display: air inlet temperature/air outlet temperature/peristaltic pump speed/air volume/pin frequency.

●Laboao's innovative drying air system can achieve low temperature drying

●Fully automatic control: one-button start-up, after setting the spray process parameters, the temperature reaches the predetermined temperature, the peristaltic pump starts automatically, the running animation is displayed on the touch screen, and the running process is clearly displayed; just press the stop button when shutting down, the machine will automatically shut down safely .

●Manual control: If you need to adjust the process parameters during the experiment, you can easily switch to the manual state to set the parameters.

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

●Shutdown protection function: Just press the stop button when shutting down, the machine will stop running immediately except for the fan, and ensure that the heating part of the equipment will not be burned out due to misoperation (forcibly turning off the fan).

●The spraying, drying and collecting systems are made of high-quality stainless steel, so that the drying process can be carried out in a pollution-free environment.

●Built-in imported oil-free air compressor, the particle size of the powder is normally distributed, the fluidity is very good, and the noise is very low, less than 60db.

●The atomization structure of the two-fluid spray, the whole machine is made of high-quality stainless steel material, the design is compact, and no auxiliary equipment is required.

●The design of drying temperature control adopts real-time regulation PID constant temperature control technology, which makes the temperature control in the whole temperature area accurate, and the heating temperature control accuracy is ±1℃.

●The feeding volume can be adjusted by the feeding peristaltic pump, and the minimum sample volume can reach 50ml.

●The particle size of the finished dry powder after drying is relatively uniform, and more than 95% of the dry powder is in the same particle size range.

●For viscous materials, there is a nozzle cleaner (through needle), which will be automatically cleared when the nozzle is blocked, and the frequency of needle through can be adjusted automatically.
