Product Detail:

1500 laboratory spray dryer

1. The miniature laboratory spray dryer (small spray dryer) has a compact design. It can be independently placed in the laboratory or on a specially designed stainless steel frame. It is self-contained and can run without other facilities. One-button startup, large color LCD touch screen operation, two operation modes of fully automatic or manual monitoring can be adopted, which is convenient for operation and monitoring of the experimental process. It is a spray dryer with small size, low noise and excellent drying effect.

2. Main features

●Original 316 material nozzle, high efficiency.

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

●Automatic control: One-button startup, after setting the spray process parameters, the temperature reaches the predetermined temperature, the peristaltic pump starts, 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 through needle can be automatically adjusted.

●Shutdown protection function: Just press the stop button when shutting down, and 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 spray, drying and collection system is made of high-quality 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, 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 the drying temperature control adopts real-time regulation PID constant temperature control technology to make the temperature control of the whole temperature zone 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.

●The finished dry powder after drying 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), when the nozzle is blocked, it will be automatically cleared, and the frequency of the needle can be automatically adjusted.

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

●The air volume of the fan is adjustable, with a special protection function, the fan will not start, and the heating will not start.
