An Electric Tray Dryer is a type of convectional drying equipment. It uses fans to circulate hot air and is ideal for drying hygroscopic materials. Unlike other drying equipment, an Electric Tray Dryer uses electricity. Its fans circulate hot air over the solids in the drying tray, removing moisture from them partially or simultaneously. It is an excellent choice for many applications, including food and chemical production.
Tray Dryer is a Convectional Drying Equipment
A tray dryer is a type of convectional drying equipment that entails passing hot air over a wet solid, which is spread out across a tray arranged in a rack. It is the most basic type of drying equipment, and is most widely used in the food and pharmaceutical industries. Its basic functionality enables it to dry practically any solid material, and its operating time ranges from twelve to forty-eight hours.
Tray dryers are available in a range of sizes and are simple to operate. They are simple to clean and operate, and can be easily customized to fit different needs. Shree Bhagwati Machtech (India) Pvt. Ltd., a leading manufacturer of these dryers, has developed a tray dryer specifically for rapid, continuous drying processes. Its unique design allows the trays to be placed in different orientations, with the heated surface outside the chamber. It also features a feeding system to ensure even drying.
Electric Tray Dryer Fans to Circulate Hot Air
A tray dryer is a closed chamber in which a heat transfer takes place through hot air circulation. These dryers are equipped with blower fans to ensure that the hot air is circulating in a proper manner. The heat is transferred through the air, which is partially or fully heated and then cooled. Tray dryers are typically double-walled and constructed with a rigid framework. They also feature a steam heating attachment. The drier body is insulated from the outside. The control panel is installed on the body of the dryer.
The best trays dryers use fans to circulate hot air through the trays, where materials are spread out to be dried. These trays may be lined with paper, or disposable paper can be used as liners. The trays are generally supported by perforated steel or wire mesh. This allows for even heating of materials on each level. If desired, a tray dryer can be customized to suit the needs of any manufacturer.
Electric Tray Dryer is Best for Drying Hygroscopic Materials
The Electric Tray Dryer is an ideal machine for drying hygroscopic materials. Unlike the traditional drum dryers, it controls the amount of air that is delivered to the trays. The materials that need to be dried are spread out on the trays.
The process of drying is characterized by a high energy consumption. This is because hygroscopic materials require high heat. The temperature of an electrically heated material must be set to a certain temperature for it to dry. The temperature should be adjusted to a certain value, or else the heating will be ineffective. Microwave power is most efficient in the early stages of drying because it allows for a higher heating rate.
Electric Tray Dryer is Less Expensive than Vacuum Tray Dryer
Vacuum and electric tray dryers are both useful for drying materials. However, these two types of dryers have some key differences. Vacuum dryers use a vacuum to maintain the drying process and electric dryers use a fan to distribute air across the trays. Both types of dryer’s dry materials in batches and are easy to use. Electric dryers are more affordable than vacuum dryers, but both can dry materials very efficiently.
The Bottom Line
Electric trays and vacuum trays are less expensive than manual troughs. Manual trays are typically smaller than vacuum trays and are difficult to access. Steam base drying is difficult with manual trays, but these dryers work well for solid materials. They are usually placed near workstations in a pharmaceutical laboratory. They need to be cleaned regularly to avoid contamination and must be adjusted regularly. Manual dryers also require frequent temperature adjustments. Excessive exposure to heat can cause contamination of the substance inside the bottle.
