Introduction to Small Spray Dryer QFN-8000S

The QFN-8000S is a laboratory-scale small spray dryer developed by Shanghai Qiaofeng Industrial Co., Ltd., designed for universities, research institutes, and enterprises in the food, pharmaceutical, and chemical industries. It is ideal for preparing small quantities of powdered particles. Utilizing spray drying technology, this equipment rapidly converts liquid materials such as emulsions and suspensions into uniform powders. It is particularly suitable for heat-sensitive substances (e.g., biological products, enzyme preparations) due to its instant heating feature, which effectively preserves active ingredients.

Key Features

1. High-Efficiency Drying

   • Equipped with a dual-fluid atomization structure and high-pressure nozzle, maximizing the contact area between droplets and hot air.
   • Drying time: 1.0–1.5 seconds; moisture evaporation capacity: 1500 mL/h.

2. Intelligent Control

   • Color LCD touchscreen for real-time parameter monitoring (temperature, airflow, peristaltic pump speed, etc.).
   • Supports one-touch start/stop and manual/automatic mode switching.
   • PID temperature control with adjustable inlet air temperature up to 250°C (±1°C precision).

3. Safety Design

   • Self-cleaning needle function prevents nozzle clogging; automatic heating cutoff upon shutdown to avoid operational errors.
   • High-borosilicate glass drying chamber and SUS304 stainless steel housing, ensuring corrosion resistance and visibility.

4. Low Noise & Eco-Friendly

   • Built-in oil-free air compressor with noise levels below 60 dB.
   • Closed-loop system minimizes dust leakage.
