double cone rotary vacuum dryer drying mode and operation
In the whole field of drying equipment, double cone rotary vacuum dryer is very competitive. Today, I would like to summarize the drying method selection and operation steps of the double cone rotary vacuum dryer. If you need it, please have a look.
double cone rotary vacuum dryer selection of drying mode :
The heating capacity and cooling capacity of the double cone rotary vacuum dryer are required to show the heat value and cooling capacity respectively. Therefore, the temperature rise by hot steam or the temperature reduction by cooling circulating water will be experienced in the cylinder.
Increasing the temperature of hot material can accelerate the heating rate and reduce the drying time. For raw materials with high viscosity, high temperature of hot material is easy to cause caking. Reducing the cooling water temperature can accelerate the cooling rate and reduce the cycle time.
With the different characteristics of raw materials, the appropriate temperature can be selected, and the method of variable temperature drying is still suitable, that is, in the early stage of drying, the temperature is low, and slowly increase the temperature to expand the drying rate.
For this point, it is suggested that temperature sensing technology compnents can be used to make the operation of heat or cooling capacity in the double cone rotary vacuum dryer change during operation, and the temperature used in different time ranges can be set by using the order, which requires the setting of time temperature correlation.
double cone rotary vacuum dryer operation steps:
The raw materials to be dried are added to the double cone rotary vacuum dryer (powder, fine granular and slurry raw materials are fed by vacuum pump), and then the feeding plug is closed. After closing the vacuum valve, turn on the mechanical pump to make the dry container air pressure.
Cover the main power switch, start the motor, press and hold the working button, the dryer equipment has just started to rotate. Open the gate valve of the heat carrier, let the heat carrier enter the compartment of the dry vessel, and inspect according to the processing technology.
After the raw materials are dried, the heat carrier gate valve is closed first, and then the cooling circulating water is introduced into the interlayer. After the raw material water is cooled to normal temperature, the vacuum packaging is terminated. Open the vacuum valve, turn off the motor, stop the rotation of the dryer, and open the plug for feeding.
As a kind of drying equipment, vacuum dryer has obvious advantages and broad market prospects. Vacuum dryer not only improves the drying efficiency of materials and ensures the drying quality, but also has the characteristics of green environmental protection, which meets the requirements of green environmental protection advocated by the state. However, users still need to pay attention to some problems in operation to ensure the safety of vacuum dryer.
