In the food sector, industrial tray dryers dry moist goods, including cereals, fruits, and vegetables. Stainless steel trays are frequently piled on top of one another to create tray dryers. A tray dryer blows hot air across the trays at a predetermined temperature. The heated air that cycles through the trays dry the product by evaporating the water from the surface. They are usually constructed from several stainless steel trays placed on one another. A blower blows hot air across the trays at a predetermined temperature. The heated air that cycles through the trays dry the product by evaporating the water from the surface.
Types of Tray Dryers
Tray dryers come in different sizes and features. However, one can get three primary try dryers categories.
Batch tray dryers
Batch industrial tray dryers run the product through several heated chambers on a conveyor belt. The item is then placed on a cooling tray and taken to an area for unloading. The ability of batch tray dryers to create uniform drying rates for various materials is their key advantage. That is particularly crucial when working with products with similar water content but varied forms and sizes. Pharmaceutical and food industries both employ batch tray dryers. They are made to dry pastes, liquids, powders, and grains.
Semi-continuous tray dryers
One kind of tray drier is the semi-continuous tray dryer. It is used to prepare biodegradable garbage, food, and delicate fabrics to heat and water. A revolving screw spreads the material across trays continuously in a semi-continuous drier. Steam or hot air is then used to heat the trays. When the material has adequately dried, it moves to the following production stage. Due to their lower heat input rates compared to continuous flow dryers, they provide a higher level of energy efficiency and product quality. Thanks to their flexible design, they are customizable to meet customers’ needs with various drying durations, throughputs, or capacity requirements.
Cross-flow tray dryers
Cross-flow industrial tray dryers force hot air up through the trays from the machine’s bottom. Hot air enters the engine at the top and spreads horizontally over each tray, drying the product’s entire surface area. This approach dries things considerably more quickly than conventional procedures, which require more time because there is no direct contact with heat. Additionally, this method completely avoids contact with damp surfaces, which can result in the growth of bacteria that would otherwise be present in a conventional system. The material cools after complete drying before delivery to a storage location. A cross-flow tray dryer has several advantages compared to other industrial dryer types, including reduced dust, less noise, and the capacity to dry various materials. Industrial trays dryers with a cross flow are primarily made up of walls.
Industrial tray dryers are quicker and more effective than conventional drying techniques. Additionally, they are more eco-friendly, which is crucial for many businesses with sustainability objectives. Drying trays are valuable in various fields, from food production to the pharmaceutical industry. Different items and materials can be dried using them, and compared to other methods, they are more affordable and produce more reliable and consistent results.
