1) Electric heating sandwich pots should be inspected for each transmission part before each shift, and add lubricating oil to avoid dry grinding and damage the equipment.
2) Check whether the electrical circuits are in good condition, whether the connection is safe and firm, whether the fuses match, and everything is complete and correct before heating.
3) Check the amount of heat transfer oil before starting the machine. The amount of oil added is 8 cm below the fuel filler.
4) In the normal use process, the two oil inlets on the upper edge of the pot body can not be blocked after the oil is added, and the heating is used. The power supply must be turned off after the daily operation.
5) The operator can't operate with water during operation. When there is oil leakage on the outside, stop the operation.
6), the temperature should be strictly controlled during operation, under normal circumstances, the control is below 200 degrees.
7) Whenever you change the oil, you should first remove the electric heating tube, clean it with alkaline water and then add it.
8) For every 20 pots of heat transfer oil, the oil should be changed once. The oil should be discharged every one month, so as not to affect the heat conduction effect. Add 40 ° C, soak 2% lye in the jacket for 2 hours, then rinse with hot water, then add oil.
9), every six months after the maintenance, including: replacement of electric heating pipes, various gaskets and electric heating pipe lines, calibration thermometers and so on.
10), electric heating and stirring the sandwich pot must first add the solution of the material, then input the material, start the stirrer, and then turn on the electric heating power to reach the temperature required by the process. Before the discharge, the electric heating power should be turned off. After 2~3 minutes, the stirrer should be turned off. After the processing is finished, the sandwich pot should be rinsed with warm water as soon as possible, brush the sticky materials, and then use 0~50 °C alkaline water. Thoroughly clean the inner wall of the container and rinse it with water. In particular, if there is no material in the pot (heat absorption medium), the electric heating source should not be turned on under the condition of empty pot. Pay special attention to the operating temperature and not exceed the rated working temperature of 200 °C.
