Tray Dryer is a hot air dryer which dehydrates drugs, chemicals, foods, herbal medicines and other laboratory samples. This is achieved by the process of circulating hot air around the samples contained in trays inside an insulated chamber where there is evaporative removal of moisture.<\/p>\n

There are many kinds of tray dryers of different sizes for laboratory and industrial uses. Whereas the normal tray dryer can be used in conventional hot air drying, the vacuum tray dryer can be considered for some heat sensitive substances.<\/p>\n

In this guide, you will learn about the theory, working, kinds, uses, advantages, specification, cost and selection of tray dryer.<\/p>\n

Bionics Scientific is one of the reputed manufacturers of tray dryers in India. The company provides a high-efficiency drying system that ensures efficient temperature control and durable and energy-saving operation.<\/span><\/p>\n

What is a Tray Dryer?<\/b><\/h2>\n

A tray dryer is an equipment that is operated through a hot air drying process and in which products are dried on stainless steel trays enclosed in an insulated chamber. Hot air is circulated in the chamber with the help of a blower and allows moisture to get evaporated.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Principle of the drying system<\/b><\/h2>\n

The drying system works on the forced convection principle. The air is evenly circulated in the chamber by the blower and heated by electric heaters. Heat from the hot air is transferred to the substance, thus making moisture evaporate. Moist air is exhausted out of the chamber to facilitate effective and even drying.<\/span><\/p>\n
