Small-scale Chinese Herbal Medicine Laboratory Spray Dryer

【Principle of Small Chinese Herbal Medicine Laboratory Large-Particle Spray Dryer】YC-018 Small Chinese Herbal Medicine Laboratory Large-Particle Spray DryerAdopts a menu-based microprocessor controller, allowing direct setting of inlet temperature, airflow, automatic needle-cleaning frequency, and peristaltic pump speed, enabling data collection as well as process monitoring and control. The self-priming peristaltic pump draws the sample liquid from the container through the nozzle into the drying chamber, while compressed air enters the drying chamber from the outer sleeve to atomize the liquid. Hot air enters from the top and meets the atomized liquid droplets, initiating the drying process. The dried powder particles are separated from the exhaust gas via a cyclone separator and collected into a collection bottle, while the exhaust gas is discharged directly into the atmosphere or through an air filtration device via a flexible hose.
【Introduction to Small Chinese Herbal Medicine Laboratory Large-Particle Spray Dryer】The small Chinese herbal medicine laboratory large-particle spray dryer (laboratory spray dryer) is a carefully developed product by Shanghai Yacheng Instrument Equipment Co., Ltd. in collaboration with PILOTECH in the field of laboratory spray drying. The unit features a compact design and can be independently placed in a laboratory or mounted on a specially designed stainless steel frame, operating as a self-contained system without requiring additional facilities. One-key startup, large color LCD touch screen operation, with both automatic and manual monitoring modes available, facilitating operation and experimental process monitoring. It is currently the smallest in volume, lowest in noise, and highly effective in drying performance among spray dryers. It has been selected by over 1,500 universities, research institutes, and enterprises, including Tsinghua University, Peking University, Shanghai Jiao Tong University, Hong Kong University of Science and Technology, Nanjing University, Wuhan University, Huazhong University of Science and Technology, Chinese Academy of Sciences, Zhejiang University, Tongji University, South China University of Technology, Jinan University, Nankai University, Southeast University, China Agricultural University, and General Electric. It is currently the smallest in volume, lowest in noise, and offers the widest particle size range (10–100 microns) for laboratory spray granulation, with excellent drying performance.
【Equipment Features】Many laboratories require relatively large particles, but conventional laboratory spray dryers typically produce particles in the range of 2–20 microns. To obtain large particles, secondary granulation after spray drying is necessary, which is time-consuming and labor-intensive.YC-018 Small Chinese Herbal Medicine Laboratory Large-Particle Spray DryerThe ability to obtain large particles up to 100 microns in a single step makes it an excellent tool for scientific research in industries such as catalysis. 
【Applicable Scope of Small Chinese Herbal Medicine Laboratory Large-Particle Spray Dryer】Primarily suitable for producing微量颗粒 powders in laboratories of universities, research institutes, and food, pharmaceutical, and chemical enterprises. It has broad applicability to all solutions, such as emulsions and suspensions, and is suitable for drying heat-sensitive materials, including biological products, biopesticides, and enzyme preparations. Due to its innovative structure, the inlet air temperature can be as low as 110°C (while conventional spray dryers require a minimum inlet temperature of 180°C). Since the sprayed material is only heated when atomized into fine droplets, it is subjected to instantaneous heating, preserving the activity of these materials without damage after drying.

【Features of Small Chinese Herbal Medicine Laboratory Large-Particle Spray Dryer】
Large color touch screen operation, combining fully automatic and manual control, a domestic first:
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.
Manual control: For adjustments to process parameters during the experiment, it can be easily switched to manual mode, with the entire experiment process dynamically displayed on the color touch screen (animation).
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).
The spray, drying, and collection system is constructed with high-quality stainless steel and high-borosilicate glass in a hybrid structure, ensuring the spray drying process operates in a pollution-free and highly stable environment. This also allows direct observation of the entire spray drying experiment, providing great convenience for researchers to monitor the process and results, and enabling timely identification and resolution of issues. All components are easy to disassemble and clean.
Fully oil-free air compressor, with particle size distribution following a normal distribution, excellent flowability, and very low noise, below 60 dB, meeting national laboratory noise standards.
Two-fluid spray atomization structure, with the entire machine precision-manufactured from high-quality stainless steel, compact design, no auxiliary equipment required, easy to use, and long-lasting like new.
To meet user requirements for adjusting various parameters within the experimental range, the drying temperature control adopts real-time PID constant temperature control technology, ensuring accurate temperature control across the entire range, with heating control accuracy of ±1°C.
Feed rate can be adjusted via the feed peristaltic pump, with a minimum sample volume of 50 ml.
For viscous materials, a nozzle cleaner (needle) is provided, which automatically clears blockages when the nozzle is clogged, with adjustable cleaning frequency.
Innovative spray head air-cooling structure, with an upgraded water-cooled spray head device, more environmentally friendly and efficient.
