Three practical applications of double cone vacuum dryer

1, double cone vacuum dryer low temperature (100 ℃) heat source problem
Double Cone Vacuum Dryer Dry heat-sensitive products, the traditional double cone are used hot water heating method. Hot water heating not only need hot water tank, hot water pump and pipe a set of cumbersome, due to hot water heat to heat, import and export must exist temperature difference, hot water outlet temperature low natural heating and drying effect is much lower than the hot water inlet, so Hot water heating temperature difference is not conducive to dry.
After the large-scale double cone vacuum dryer is still hot water heating, due to a substantial increase in drying equipment load and the need for a substantial increase in heat load, hot water heating system, a set of cumbersome also concocted, not only a lot of equipment investment , But also to the efficiency of the drying equipment to bring a lot of disadvantage. But if the use of saturated water vapor as a heat source, as long as the strict control of the double cone heating jacket within the temperature or pressure to ensure that the temperature or pressure in line with the heating temperature requirements of the saturated water vapor physical parameters to ensure that the jacket will be timely steam condensate Water out. You can use 0.2 MPa of saturated water directly to the double cone of low temperature heating heat source. Of course, large-scale double cone vacuum dryer jacket within the larger space, just when driving the jacket (especially within the heating plate) there are a lot of inert gas must be discharged clean, otherwise it will seriously affect the normal operation, the best The method is to vacuum and then add saturated water vapor.
 
2, the study of thinning large-scale double cone vacuum dryer equipment wall thickness problem
Today's world are considering energy-saving emission reduction, up to the aircraft down to the train car, are trying to reduce the thinning in the structure. Associated with the double cone vacuum dryer carrying a large boiler (heating jacket), it seems necessary to save energy from energy saving, saving stainless steel and improve the efficiency of heating and other aspects of research, in the field of drying technology can also make our contribution.
3, the structure of the heating plate to strengthen
Conventional hollow thin inner heating plate must be strengthened by plug welding. Because the wall thickness of the inner heating plate is only 2 ~ 3 mm, both sides of the hollow heating plate need to be perforated. It is difficult to strictly process the groove on the sheet. There is a drug GMP requirements of the heating plate in the welding must be polished after polishing, so in many of the solder joints in the existence of a slight weak links, it will be in the future production operations in the sudden burst due to local rupture caused the entire heating plate blasting. Double cone vacuum dryer traditional thin plate welding reinforcement structure is easy to leave this hidden danger.
 
We learn a lot in the new double cone vacuum dryer inside the heating plate to strengthen the structure of the use of articulated non-destructive welding reinforcement technology, the heating plate on the double-sided motherboard is no longer perforated, so as to avoid the hole plug welding operation brought Of the ills, eliminating the double cone vacuum dryer is essential when the internal heating plate processing of the actual problems.
