    Laboratory spray dryer operation rules 1, experimental spray dryer (spray dryer) principle of operation: laboratory spray dryer is a menu micro processing controller, can directly set the inlet temperature, gas flow rate, automatic needle frequency, pump speed, data collection and process monitoring and control The self priming peristaltic pump enters the liquid chamber from the container through the nozzle, and compresses the air from the outer casing into the drying chamber to make the liquid atomized The hot air comes into the liquid particles from the upper layer after spraying with the spray, and the articles begin to dry After drying, the powder particles are separated from the exhaust gas through the cyclone separator and enter the collecting bottle, and the exhaust gas is directly discharged into the atmosphere through the diameter hose Air filter Two The main features of the experimental spray dryer (spray dryer) are: 1 the spray dryer produced by Chuan Yi instrument is made of transparent high quality borosilicate heat-resistant glass material by spray, drying and collection system The spray drying process is carried out in a pollution-free and Zui stable environment The spray drying experiment process can be directly observed, which provides great convenience for scientific researchers to control the experimental process and the experimental results And can timely adjust to find and adjust problems All glass components are easy to disassemble and clean 2 atomization structure of two fluid atomization, the whole machine is made of high quality stainless steel, with compact design, no auxiliary equipment and convenient operation 3 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 4 In order to keep the sample pure, the air inlet filter is equipped 5 The feed quantity can be adjusted by the feed pump, and the sample quantity of Zui can reach 50ml 6 After drying, the particle size of the dried powder is relatively uniform, and more than 95% of the dried powder is in the same particle size range 7 Equipped with nozzle cleaner (through needle), it will automatically clear when the nozzle is blocked 8 Humanized operation panel, double modes of automatic operation and manual operation, convenient switching, mastering the experimental process as you wish, all parameters have LCD display 9 Very low noise, Less than 60dB three, experimental spray dryer (spray dryer) operation instructions: 1 Peristaltic pump: click "open", peristaltic pump "start", and then click "stop" to close. automatically control the operation of peristaltic pump, click the peristaltic pump auto button green (the button changes to "start"), peristaltic pump auto start, you can adjust the speed of peristaltic pump according to the set value of air outlet temperature, so as to adjust the feed volume of peristaltic pump 2 Fan: control the start and stop of the fan, click the fan button area (above), the fan starts (the button moves to "start"), click the below, the fan stops (the button moves to "stop") 3、 Needle passing: control the start and stop of needle passing Click the green area (above) of the button to start needle passing (the button moves to "start"), click the bottom to stop (the button moves to "stop") The running speed of needle passing is changed by changing the set value of needle passing in the interface (three) It has been set before leaving the factory and does not need to be changed 4 Air compressor: control the start and stop of the air compressor, click the green area (above) of the air compressor button, the air compressor starts (the button moves to "start"), and click the bottom to close 5 Heater: control the start and stop of electric heater, click the green area (above) of heater button, heater starts (button moves to "start"), click the bottom, heater stops (button moves to "stop") Note: the heater will not be started before the fan is not started After the heater is closed, the fan will be automatically closed when the air inlet temperature is less than 30 ℃ 6 Fan setting: set the rotation frequency of the extension, press the value box, pop up the number keyboard, press the CLR key to clear the number, then input the required value, and press enter to finish the modification 7 Manual operation of peristaltic pump: manually control the operation of peristaltic pump, click the green area (above) of the peristaltic pump automatic button (display on), the peristaltic pump will start automatically, display below, and the peristaltic pump will stop (display off) 8 Through needle setting: through the operation frequency of through needle, the value represents to start once in a few seconds Press the value box, pop up the number keyboard, press CLR key to clear the number, then enter the required value, press enter key to modify it, and the Zui good value has been set in the field, no need to set it separately 9 Setting of peristaltic pump: set the feeding amount of peristaltic pump ml / min), press the value box, pop up the number keyboard, press CLR to clear the number, then input the required value, and press enter to finish the modification 10 Description of the experimental spray dryer: click the control panel to enter the interface (two) and enter the temperature setting interface.
