FDG Indirect Gas-Fired Dehydrators are different from other drying units. Unlike a direct-fired unit, the burner is fired into a tube-type heat exchanger; therefore, the product’s combustion does not contact recirculated air or the product in the drying chamber.

Each system includes the burner assembly, an insulated drying chamber, air handling components, and PLC-based electrical controls with an operator screen. 

What Capacity Do You Need?

Which water removal rate best fits your process? Ideal rates are highly product-dependent. However, it can be calculated with three measurements of your existing process: product wet weight, product dry weight, and time from wet to dry.

By finding the product weight change (wet weight minus dry weight) and dividing this by the time measurement (in hours), you can find the average water removal rate (in pounds per hour) occurring in your current process. Next, you can scale this number based on the amount of wet product you wish to start with or the amount of dry product you want to end with. Now, you need to decide how much drying area you need.
