Working Principle: 

CT-C Tray Dryer (also called chamber dryer or drying oven) is the most commonly used convective chamber dryer, capable of drying or heating various kinds of wet materials from liquids to bulk solids. Inside the drying chamber, trays loaded with wet material are placed on top of each other in trolleys. 

In drying process, fresh air is sucked into the drying chamber by the circulation fan and flows through the built-in electric heater or steam heat exchanger to get required temperature. With the help of air distributor, hot air evenly flows through each layer of trays for heat transfer and carries away the evaporated moisture. Most of the hot air is forced to circulate inside the drying chmaber to save energy, while small amount of damp air is discharged via a draft fan or air valve. After drying, open the chamber door and pull the trolleys out for unloading the dried product. 

Technical Features: 

• Fast and uniform drying: Air distributor is installed in both sides of the drying chamber so that hot air is forced to evenly flow through each layer of tray for uniform heating. The temperature difference inside the drying chamber is less than ±2 ℃. 
• Energy-saving: The drying chamber is well heat-insulated and the design of forced circulation of hot air minimize the heat loss in the drying process. 
• Versatile in application: Different types of tray are available to optimize the drying effect of different raw materials. 
• GMP sanitary design: The tray dryer is made by SUS304 or SUS316L stainless steel and well polished without blind angle for cleaning. 
• Flexibility in heat source: The heat source can be electricity, steam, hot thermal oil or oil/gas fired hot air generator. 

Technical Parameters:

Note: The built-in heat source can be electric heating elements or steam heat exchanger. When use steam, the max drying temperature is about 140 ℃.  

FAQ: 

Q: What information is needed in order to get a quote?
