Intelligent integrated distillation instrument is an efficient and intelligent instrument and equipment designed for food testing, which is mainly used for the determination of moisture in food samples, the extraction of organic matter, etc., and is usually used in food testing, chemical analysis, environmental monitoring and other fields.
The intelligent integrated distillation instrument is mainly composed of the main parts such as the pot body, the distillation tube, the heater, the electric control box, the water tank, etc., which is simple to operate and easy to maintain, and is widely used in laboratories, enterprises and institutions.
Working principle: through the water inlet set at the top of the condenser pipe can be communicated with the water supply pipe, through the action of the solenoid valve on the water inlet during distillation, yes the gas can not enter the water supply pipe, yes the distillation work can be carried out normally, when the distillation is over, the solenoid valve will automatically open, so that the water inside the water supply pipe can enter the condenser pipe from the water tank under the action of the booster pump, and clean the inside of the condenser pipe, so that the residue of the last distillation will not affect the follow-up work, Make the final detection result more accurate, through the buffer pipe that is arranged inside the box, the condensed liquid can be poured into the buffer chamber slowly, and the inside of the buffer chamber is set up as an inclined plane, so that the residence time of the liquid in the inside of the box can be increased, so that the suction pipe has enough time to suck out the harmful gas produced during distillation, the harmful gas can not appear "backflow" phenomenon under the effect of the check valve, and the harmful gas can enter the gas gathering tank under the action of the vacuum pump. People can deal with it centrally, so that it can effectively avoid the harm it causes to people's health.
Steps:1Preparation before operation: determine the purpose and method of the experiment, select appropriate samples and reagents, carry out personal protection, and check whether the equipment is normal.
2.Dispensing: The sample to be tested is added to the sample container and the sample is added to the boiler through a dosing hopper and pump.
3.Set the program: Through the computer control system, set the parameters such as temperature, pressure, liquid level, etc., and start the program.
4.Start heating: Start the boiler, start heating, and after the pressure and temperature in the boiler are stable, the automatic distillation instrument will start to run automatically.
5.Collect liquid: The liquid in the evaporator is cooled and collected at the same flow rate as the volume added to the sample container in the boiler.
6.End of procedure: When the automatic distillation instrument is finished, the boiler is turned off and the collected sample is sent to the next experimental operation.
7.Cleaning equipment: Cleaning and disinfection of used equipment and piping, especially inside the boiler and liquid phase sensors.
Precautions for operation:
1.During the heating period of the automatic distillation instrument, the changes in pressure, temperature and liquid level in the boiler should be paid close attention to, and if any abnormalities are found, they should be stopped and checked in time.
2.The collected distillate should be collected in the specified volume, stored in the appropriate bottle and marked with a detailed sample number and date.
3.At the end of the operation, the instrument needs to be thoroughly cleaned and disinfected to ensure the accuracy of the data for the next experiment.
