HF-3L small spray dryer

HF-3L small spray dryer (small spray dryer/pilot spray dryer) and it is mainly suitable for the production of micro-particle powder in universities, research institutes and laboratories of food, medicine and chemical enterprises. It is suitable for all solutions such as emulsions and suspensions. It has broad-spectrum applicability and is suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc., because the sprayed materials are only exposed to high temperature when sprayed into mist-like particles, so they are only heated instantly. It can keep these active materials after drying and still maintain their active ingredients undamaged. Main features of 3000Y spray dryer


Main features of stainless steel small spray dryer;

● Hefan refined nozzle (two-fluid nozzle) has high efficiency. (Optional centrifugal nozzle)

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

● Fully automatic control: One-button startup, after setting the spray process parameters, the temperature reaches the preset 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 when shutting down, and the machine will automatically and safely shut down .

● Manual control: If you need to adjust the process parameters during the experiment, you can easily switch to the manual state, and the whole experiment process is displayed dynamically on the color touch screen (animation)

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

● Shutdown protection function: just press the stop button when shutting down, the machine will stop running immediately except for the fan, ensuring that the equipment will not burn out the heating part due to misoperation (forcibly turning off the fan).

● The whole system is made of stainless steel, so that the drying process can be carried out in a pollution-free environment.

● Built-in Taiwan Dolphin oil-free air compressor, the particle diameter of the powder is distributed normally, 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, and the design is compact, without auxiliary equipment.

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

● In order to maintain the purity of the sample, it is equipped with an air inlet filter.

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

● After drying, the finished dry powder has a relatively uniform particle size, 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 the needle can be automatically adjusted.

● Innovative tower wall purging device, higher material recovery rate.

Special protection function, the fan can't start, the heater can't start.
