Vacuum dried to eliminate surface hardening and dried under atmospheric conditions prone. Atmospheric air drying, the surface is dry material to form a fluid boundary layer, heat of vaporization of water vapor into the air through the fluid diffusion boundary layer, DRYING To surface water movement, if it is moving as fast as the boundary surface evaporation rate, boundary water film will burst, the surface is dry material will be localized cracking phenomenon, then extended to the entire outer surface, forming a surface hardening. Between the vacuum dried material and surface pressure difference is large, at a pressure gradient effect velvet dryer how much money, and soon moved to the surface of the water, surface hardening does not occur.

Advantages: flash dryer phosphor dryer suppliers, vibration fluidized bed dryer, belt dryer, spray dryer, paddle dryer, air dryer, tray dryer, sludge dryer, vacuum dryer and the like. Caution before vacuum dryer: 1, if not long, should unplug the power cord to prevent equipment damage people. And should be regularly (usually a quarter) run 2-3 days according to the conditions of use in order to get rid of moisture dryer electrical parts to avoid damage on the device 2, plug in the power Changzhou fries dryer, digital display temperature controller, and set temperature and the heating mode (where the temperature can reach full power heated stalls 1, when the thermostat hit half-power heated stalls 2). 3, flammable and volatile chemicals Never placed inside a vacuum dryer. 4. After setting, long-term preservation of the data. Oven into the heating state, heat indicator (green) light. When the temperature near the set temperature, traffic lights staggered, repeatedly, control goes to a constant temperature. 5, vacuum dryer equipment surfaces and interior walls of the box should always wipe to keep clean, increasing the transparency of glass. Do not use acids, bases or other corrosive solution to clean the outer surface.
