Introduction to Small Spray Dryer

Laboratory spray drying (spray dryer/spray drying instrument) is primarily suitable for universities, research institutes, and laboratories in the food, pharmaceutical, and chemical industries to produce微量 powder particles. It has broad applicability to all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive substances like biological products, biopesticides, and enzyme preparations. Since the sprayed material is only exposed to high temperatures when atomized into fine particles, it is heated instantaneously, preserving the active components of these materials without damage after drying.

1) Qiaofeng precision nozzle, high efficiency.

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

3) Fully automatic control: one-key startup; after setting spray process parameters, the peristaltic pump automatically starts when the temperature reaches the preset value; the touch screen displays an operation animation, clearly showing the process flow; to shut down, simply press the stop button, and the machine will safely shut down automatically.

4) Manual control: if process parameters need adjustment during the experiment, it can be easily switched to manual mode; the entire experiment process is dynamically displayed on the color touch screen (animation).

5) Equipped with a nozzle cleaner (needle); when the nozzle is blocked, it will automatically clear, and the needle cleaning frequency can be adjusted automatically.

6) Shutdown protection function: when shutting down, simply press the stop button; the machine will immediately stop operation except for the fan, **preventing heating components from being damaged due to incorrect operation (forcibly stopping the fan).

7) The spray, drying, and collection system is made of transparent, high-quality borosilicate heat-resistant glass, ensuring the drying process is carried out in a pollution-free environment.

8) Built-in imported oil-free air compressor; the spray particle size follows a normal distribution, with excellent flowability and very low noise, less than 60 dB.

9) Two-fluid spray atomization structure; the entire machine is made of high-quality stainless steel, with a compact design and no need for auxiliary equipment.

10) The drying temperature control design adopts real-time PID constant temperature control technology, ensuring accurate temperature control across the entire temperature range, with a heating control accuracy of ±1°C.

11) To maintain sample purity, an inlet air filter is equipped.

12) The feed rate can be adjusted via the feed peristaltic pump, with a minimum sample volume of 80 ml.

13) The dried finished powder has relatively uniform particle size, with over 95% of the powder within the same particle size range.

14) For viscous materials, a nozzle cleaner (needle) is provided; when the nozzle is blocked, it will automatically clear, and the needle cleaning frequency can be adjusted automatically.

15) The upgraded atomization system effectively resolves the issue of certain viscous materials adhering inside the cyclone separator, preventing long-term accumulation of materials in the cyclone separator.
