1. Brief introduction of small spray dryer:
Small experimental micro spray dryer (spray dryer/spray dryer) and it is mainly used in universities, research institutes and laboratories of food, medicine and chemical enterprises to produce micro-particle powder, and has a broad spectrum for all solutions such as emulsions and suspensions Applicability, suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc., because the sprayed materials are only exposed to high temperature when sprayed into mist-like particles, so they are only heated instantly and can maintain these After the active material is dried, the active ingredient remains undamaged.
2. Main features:
Qiao Feng refined nozzles with high efficiency.
Color LCD touch screen parameter display: air inlet temperature / air outlet temperature / peristaltic pump speed / air volume / needle frequency.
Fully automatic control: One-button startup, after setting the spray process parameters, the temperature reaches the preset temperature, the peristaltic pump starts automatically, the operation animation is displayed on the touch screen, and the operation process is clearly displayed; just press the stop button when shutting down, 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 dynamically displayed on the color touch screen (animation)
Equipped with nozzle cleaner (through needle), when the nozzle is blocked, it will automatically clear, and the frequency of the 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 due to misoperation (forcibly turning off the fan).
The spraying, drying and collecting system is made of transparent high-quality borosilicate heat-resistant glass material, so that the drying process can be carried out in a pollution-free environment.
Built-in imported oil-free air compressor, the particle diameter of the powder is normally distributed, 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 material, and the design is compact without auxiliary equipment.
The design of 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, an air inlet filter (optional) is equipped.
The feed volume can be adjusted by the feed peristaltic pump, and the minimum 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), which will be automatically removed when the nozzle is blocked, and the frequency of the needle can be automatically adjusted.
Innovative tower wall purging device, higher material recovery rate (optional).
