Small-Scale Spray Dryer QFN-8000S

I.Product Introduction:

Compact Laboratory-Scale Micro Spray Dryer(Spray drying apparatus/spray dryer) primarily suitable for producing微量颗粒粉末 in laboratories of universities, research institutes, and food, pharmaceutical, and chemical enterprises. It offers broad-spectrum applicability for all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive materials including biological products, biopesticides, and enzyme preparations. As the sprayed material is only exposed to high temperatures when atomized into fine particles, it undergoes only instantaneous heating, preserving the active ingredients of these materials without degradation after drying.

II. Key Features:

1. Qiaofeng precision nozzle for high efficiency.
2. Color LCD touch screen parameter display: inlet temperature/outlet temperature/peristaltic pump speed/air volume/needle cleaning frequency.
3. Fully automatic control: One-key startup; after setting spray process parameters, the temperature reaches the preset value, the peristaltic pump starts automatically, and the touch screen displays an operational animation with clear process flow; for shutdown, simply press the stop button, and the machine shuts down safely automatically.
4. Manual control: For convenient adjustment of process parameters during experiments, a switch to manual mode is available; the entire experimental process is dynamically displayed on the color touch screen (animation).
5. Equipped with a nozzle cleaner (needle), which automatically clears blockages when the nozzle is clogged; the needle cleaning frequency is automatically adjustable.
6. Shutdown protection function: When shutting down, simply press the stop button, and the machine stops immediately except for the fan, ensuring that the heating components are not damaged due to incorrect operation (e.g., forcibly turning off the fan).
7. The spray, drying, and collection systems are constructed from transparent high-borosilicate heat-resistant glass, ensuring the drying process operates in a contamination-free environment.
8. Built-in imported oil-free air compressor; the particle size distribution of the sprayed powder follows a normal distribution, with excellent flowability and very low noise, below 60 dB.
9. Two-fluid spray atomization structure; the entire unit is manufactured from stainless steel, featuring a compact design with no auxiliary equipment required.
10. Drying temperature control employs real-time PID constant temperature regulation technology, providing accurate temperature control across the full temperature range with a heating control precision of ±1°C.
11. An inlet air filter is equipped to maintain sample purity.(Optional)。
12. Feed rate is adjustable via the feed peristaltic pump, with a sample capacity of up to 50 ml.
13. The dried finished powder has a relatively uniform particle size, with over 95% of the dry powder falling within the same particle size range.
14. For viscous materials, a nozzle cleaner (needle) is provided, which automatically clears blockages when the nozzle is clogged; the needle cleaning frequency is automatically adjustable.

Innovative tower wall purging device for higher material recovery rate.(Optional)。
