AYAN-PWGZ2000 the Laboratory vacuum spray dryer is specially developed for thermal sensitive materials. The whole machine is compact and self-contained, and can run without any other facilities. One button start-up, large LCD touch screen operation, can adopt two operation modes of full automatic or manual monitoring, which is convenient for operation and monitoring of experimental process, especially realizing instant drying of materials under low temperature conditions (50℃), providing extremely convenient and safe drying methods for heat sensitive materials, such as biological products such as enzyme preparation, active bacteria, and extracts of natural products of traditional Chinese medicine with high sugar content , high polymer materials that are not heat-resistant, materials that are vaporized in case of heat, etc.
1. the whole process of spray drying is completed in a vacuum environment. The instant drying of materials at low temperature (50 C) is realized, which greatly reduces the drying temperature of materials and solves the problem of spray drying of thermosensitive materials.
2. Color touchscreen operation: heating temperature PID constant temperature control, peristaltic pump feeding speed can be adjusted at any time.
3. Full automatic control: one button start, set the spray process parameters, display animation on the touch screen, and display the operation process clearly.
4. Manual control: if it is necessary to adjust the process parameters during the experiment, it is convenient to switch to the manual state, and the whole experiment process is dynamically displayed on the color touch screen (animation).
5. 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 heating part of the equipment will not be burnt out due to misoperation (forced shutdown of the fan).
6. The machine has the function of misoperation protection. When the fan and heater switches are pressed in the wrong order, the machine will automatically remind to prevent the novice from damaging the machine by misoperation.
7. Built in imported oil-free air compressor, the particle diameter of powder spraying is normal distribution, the fluidity is very good, and the noise is very low, which meets the National Laboratory noise standard;
8. Atomization structure of two fluid atomizing machine. The machine is made of high quality stainless steel, with compact design, no need for accessory equipment, and convenient use.
9. Spray, drying and collection system is made of high quality stainless steel. The spray drying process is carried out in a pollution-free and stable environment. It provides great convenience for researchers to control the experimental process and experimental results, and can solve problems in time. All stainless steel components are easy to disassemble and clean.
10. For viscous materials, a nozzle cleaner (through needle) is provided. When the nozzle is blocked, it will automatically clear and the frequency of through needle can be automatically adjusted;
11. The spray head is a concentric spray head. When atomizing, it ensures that there is no eccentricity and leads to one side of the bottle wall. The spray head can be moved up and down after installation, so as to adjust the atomization position and improve the spray drying effect.
12. In order to meet the user's requirements of adjusting various parameters in the experimental range, the real-time PID constant temperature control technology is adopted in the design of drying temperature control to make the temperature control in the whole temperature area accurate and the heating temperature control accuracy is at ± 1 ℃.
13. The feed volume can be adjusted by the feed peristaltic pump, with the rated processing capacity of 1500ml / h.
