Tray dryer

Tray dryers consist of several trays, which contain the materials to be dried, stacked inside the drying chamber. Air is used as a heat transfer medium that is forced to move inside the chamber. Blowers facilitate air movement. The air gains thermal energy when it contacts the heating coils. The heated air is blown on top of the material, causing the moisture to diffuse and vaporize. A portion of the moisture-carrying air leaves through the ventilation duct, while the rest is recirculated in the chamber together with a stream of fresh, dry air. The temperature and velocity of the air may be adjusted depending on a given product and operational requirements.

Overview

Tray dryers consist of several trays, which contain the materials to be dried, stacked inside the drying chamber. Air is used as a heat transfer medium that is forced to move inside the chamber. Blowers facilitate air movement. The air gains thermal energy when it contacts the heating coils. The heated air is blown on top of the material, causing the moisture to diffuse and vaporize. A portion of the moisture-carrying air leaves through the ventilation duct, while the rest is recirculated in the chamber together with a stream of fresh, dry air. The temperature and velocity of the air may be adjusted depending on a given product and operational requirements.

Tray dryers are the simplest type of industrial dryers; they have inexpensive initial costs and consume less space. They are easy to operate and maintain. However, the drying time is typically long. They may not be suitable for powdered solids.

Finishing

The design and manufacture of the dryer is of high standard of GMP and has an aesthetic look. It is buffed externally to 150 grit matt finish and internally buffed to 220 grit mirror finish.

Electric Heating

The Air inside the Tray Dryer is heated by “U” tube S.S. 304 air heaters. The heaters are fitted on the sides of the dryer to facilitate uniform heating. Maximum temperature attained inside the dryer is 100 C and will be indicated and controlled by a Digital Temperature Indicator cum Controller over full range of heating load.

The heaters will be inserted inside tubular pipe to prevent it from beckoning RED HOT. The terminals of the heaters will be through outside the dryer to make it more safe for operations for solvent based products.

Air Circulation

The special design of the Blower ensures uniform air circulation so that there is uniform air circulation so that there is uniform air current over the entire charge loaded in the Trolley inside the dryer.

Control Panel

Control Panel box consists of contactor assembly, On/Off Switch, Controller, Operating Push Buttons are incorporated in the control box.
