Energy Saving Installation

You can take some simple steps to ensure minimal heat loss during the drying process, which will pay nice dividends by reducing energy costs. See Modern vs Old Dryers

Hopper Insulation

Manufacturers do not always follow the same rules. It is up to you to ensure that the hoppers you buy have at least 2" thick insulation sandwiched between the walls of:

• Hopper sides
• Hopper access doors
• Hopper cone

It is not necessary to have insulation above the normal material level in the hopper because that is where cooler material enters the hopper and air is returning to the dryer.

Dryer Insulation

Proper application of insulation to the following dryer components can also reduce heat loss.

• High temperature flex hose carrying hot air to hopper cone
• Hard metal ducting carrying hot air to dryer cone
• High temperature flex hose carrying hot air within the dryer cabinet (depending on space and practicality)

Do not insulate the hose returning air from the top of the hopper to the dryer.

Placement of Process Heater

• This depends largely on the size of the system and the distance between the dryer and hopper
• Small systems include the process heater within the dryer cabinet
• Larger systems (where distance between dryer and hopper are greater) should have the process heater mounted on the dryer to minimize heat loss
