Small spray dryer

product manual

The spray dryer and it is mainly suitable for the production of micro-particulate powder in universities, research institutes and laboratories of food, pharmaceutical and chemical enterprises. It has a broad-spectrum applicability to all solutions such as emulsions and suspensions, and is suitable for the drying of heat-sensitive substances such as Biological products, biological pesticides, enzyme preparations, etc., because the sprayed materials are only subjected to high temperature when sprayed into mist-sized particles, so they are only heated instantaneously, which can keep these active materials from being damaged after drying. .

main feature 

●The self-developed two-fluid nozzle is more applicable.

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

●Fully automatic control: one-key start-up, after setting the spray process parameters, the temperature reaches the predetermined temperature, the peristaltic pump starts automatically, the operation animation is displayed on the touch screen, and the operation process is clearly displayed; just press the stop button during shutdown, 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, and the color touch screen dynamic display (animation) throughout the experiment

●Equipped with nozzle cleaner (through needle), when the nozzle is blocked, it will be automatically cleared, 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, to ensure that the device will not burn out due to misoperation (forced shutdown of the fan).

●The spraying, drying and collecting systems are made of transparent high-quality borosilicate heat-resistant glass materials, so that the drying process can be carried out in a non-polluting environment.

●Built-in imported oil-free air compressor, the particle diameter of the powder spray is normally distributed, the fluidity is very good, 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, compact design, no auxiliary equipment.

●The design of dry temperature control adopts real-time control PID constant temperature control technology, so that the temperature control in the whole temperature zone is accurate, and the heating temperature control accuracy is ±1℃.

●In order to keep the sample pure, equipped with air inlet filter.

●The feeding volume can be adjusted by feeding peristaltic pump, 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 sticky materials, there is a nozzle cleaner (through needle), which will be automatically cleared when the nozzle is blocked, and the frequency of the needle can be adjusted automatically.
