How to clean the spray dryer

May 17, 2021

Small laboratory spray dryers are mainly used in universities, research institutes, food and medicine, and polymer materials and chemical industry laboratories to produce micro-particle powders. They are applicable to all solutions such as emulsions and suspensions, and are 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 instantaneously, which can keep these living materials dry and still maintain their active ingredients. damage.


Main features:

1. The spray dryer adopts a large color touch screen operation, a combination of automatic control and manual control, ten-segment temperature control, with memory function, domestic weiyi:

2. 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, and the machine will automatically shut down .

3. 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 on the color touch screen dynamically.

4. Shutdown protection function: Just press the stop button when shutting down, the machine will stop running immediately except for the fan, to ensure that the equipment will not burn out the heating part due to misoperation (forcibly shutting off the fan).

5. The spray, drying and collection system is made of transparent high borosilicate heat-resistant glass material, so that the spray drying process is carried out in a stable environment, and the entire spray drying experiment process can be directly observed, so that the scientific researcher can control the experiment process and The experimental results provide convenience, and can find and solve problems in time. All glass elements are easy to disassemble and clean.

6. ​​The small spray dryer has a built-in imported oil-free air compressor. The particle diameter of the spray powder is normally distributed, the fluidity is very good, and the noise is very low, less than 60db, which meets the national laboratory noise standard;

7. The atomization structure of the two-fluid spray, the whole machine is made of stainless steel, the design is compact, no auxiliary equipment is needed, it is convenient to use, and it is as new as it is long-lasting.

8. In order to meet the user's requirements for adjusting various parameters in the experimental range, the real-time PID constant temperature control technology is adopted in the design of the drying temperature control, so that the temperature control of the whole temperature zone is accurate, and the heating temperature control accuracy is ±1℃.

9. In order to maintain the purity of the sample, it is equipped with an air inlet filter.

10. The feed volume can be adjusted by the feed peristaltic pump, and the sample volume can reach 50ml. Optional magnetic stirrer

11. The granularity of the finished dry powder after drying is relatively uniform, and more than 95% of the dry powder is in the same granularity range.

12. The small spray dryer is equipped with nozzle cleaner (through needle) for viscous materials. When the nozzle is blocked, it will be automatically cleared, and the frequency of the needle can be automatically adjusted;
