As we all know, the efficiency of hot water dewatering is relatively higher than that of cold water, and even if we use the cold strand cutting method, the most effective way to dewater is to blow hot air. That is why the water content of the pellets is high when the machine is just turned on, because when the machine is turned on, the water in the tank enters the circulation system is too low, the temperature has to be reduced, and then the heat brought out from the pelletizer by the pellets to raise the temperature.
Will someone say: you can first raise the temperature of the water tank, so that the problem will be solved. To be honest, the water tank is slow to heat up, and even slower to cool down, I have tried, our pelletizer water tank to reduce the temperature of 1 ℃ takes about 7 minutes or so. Of course, by feeding cold water into the tank to cool down fast, but sometimes it is impossible to feed cold water.
The tank water temperature is too low not only affects the dewatering efficiency in the dewatering machine, and because the water temperature is too low, it will affect the mold temperature, which brings the result that the head pressure is too high.
