CH Series Insulated Hoppers

CH Series Hoppers

Efficient Drying with Minimum Downtime

CH series drying hoppers save you time, energy and money by delivering consistent, efficient drying and fast, easy clean outs.

Conair hoppers are designed to promote even heat distribution and mass material flow to ensure adequate drying throughout the hopper. Large access doors and smooth interior surfaces keep downtime for material changes to a minimum.

We offer a wide range of hopper sizes, with capacities from 18 to 31,500 lb/ft3 {288.3 to 504,581.6 kg/m3}.

Quick-clean design

Large hinged doors, smooth walls and removable spreader cones make cleaning fast and easy.

Consistent drying time

Don’t let your material leave the drying hopper before its time. Conair’s air inlet design, smooth material/air spreaders and steep cone angles promote uniform mass material flow. This means material at every level has been exposed to drying air for the same amount of time before leaving the hopper.

Uniform air/heat distribution

Conair hoppers introduce heated drying air low in the cone of the hopper, ensuring that material at all levels in the hopper will be dry when you’re ready to process it.


Insulated side walls

Maintains temperature at desired level, prevent heat loss and protect workers from hot surfaces.

Mass material flow

Smooth surfaces and steep cone angles ensure that each pellet is exposed to heated drying air for the specified drying time

Even air/heat distribution

Even air/heat distribution throughout the hopper.The air spreader has a drop tube that forces drying air to material at the bottom of the hoppe

Large access door

A large access door, easily removable spreader cone and smooth interior walls minimize downtime for cleanout and material changes.


Floor Stand

(standard on CH39 and CH44 hoppers) Stands can be bolted to the floor or fitted with casters. Stands designed to fit over a gaylord are available for larger hopper models.

Hopper Loaders

Conair vacuum loaders and receivers mount easily to the top of the hopper. Select from a wide range of capacities to accommodate your throughput.

Distribution Boxes

Mount beneath the hopper to help convey the dried material to the processing machine.

Special Paint

Automotive or non-automotive paint (available only on carbon steel)
