Chamber Construction: Both internal and external chambers of these Vacuum Tray Dryers are made of high grades stainless steel, with a choice of customer we use M.S. / SS 304 / SS 316 / SS 316L stainless Steel. The joints are welded and made of thick stainless steel. For minimizing heat loss and maximizing efficiency thick glass wool is used in insulation. The chamber body is enclosed and covered with removable high grade stainless steel panels.

Doors: Vacuum Shelf Dryers are equipped with single and double doors. Usually double doors are used only in large capacity vacuum tray dryers. With choice of customers doors are also made of high grades stainless steel (SS304 / SS316), the bolts used in door fixing are also of 304 stainless steel. The doors are equipped with high quality interlocks to ensure maximum safe operation. The inner surface of doors is grooved to adjust rubber gasket.

With every vacuum tray drying oven one or two dummy shelves are provided in order to prevent condensation from forming and dripping into the trays on the shelf below. Mild Steel / Stainless Steel baffles are provided in the annular space to guide the flow of heating media ensuring sufficient coverage of heat transfer area and uniform heating. For easy cleaning these shelves are fitted with sufficient gap from the chamber walls.

Inlet / Outlet Headers: Inlet and Outlet headers are made of stainless steel and are fitted outside the working space of the chamber.

Optional Accessories:
Condenser: Condenser in vacuum tray drying oven is optional and made of stainless steel and designed in shell and tube type.
Condensate Receiver: This is also an optional accessory which is made of stainless steel and fitted with a glass window. Specific drainage arrangements are made for drainage of condensate.
Other Accessories: Silicon gasket or EPDM gasket for door, interconnecting piping, hot water generating system, vacuum pump and digital temperature indicator etc.
