Vibrating Fluid Bed

Designed to dry and/or cool a variety of products at a wide variation of feed rates.

Vibrating fluid beds are well suited for the following applications:

• Processing of material that has a wide particle size distribution. Vibration will help to discharge oversize particles that will not fluidize.
• Processing of sluggish or sticky materials.
• Processing of temperature sensitive materials. A subfluidized condition can be created to produce plug flow and eliminate burning or discoloration.
• Processing of fragile materials. Low amplitude vibration and reduced fluidizing velocity create a gentle bed, which causes less degradation than conventional fluid beds or other mechanical dryers.

Carrier conventional fluid bed

Carrier conventional fluid beds are designed to dry and/or cool a variety of products without the aid of vibration. Fluid bed processing passes a gas directly through a bed of solid material via a perforated plate, nozzles, or other fluidizing media, thereby lifting and mixing the solids.

Sanitary, U.S.D.A (3A) approved construction.
Easily cleaned, rugged construction, dust tight, and low maintenance.

Tornesh dryer

The Tornesh dryer is an innovative drying device combining many of the benefits of fluid bed and flash drying. The unit can process wet solids ranging in size from 1 micron up to 1/2 inch diameter.

• Direct-type dryer capable of drying wet solids for multiple industries including food, dairy, pharmaceutical, grains, solid chemicals, minerals and ores.
• Materials to be dried fall to the bottom plenum of the unit and begin to swirl in a cyclonic pattern like a tornado. As moisture is removed from the product, it becomes lighter and eventually is entrained in the upward hot gas stream.

Air Knife System

The Carrier air knife system provides an effective, efficient means of separating heavy metal, stone, plastics, paper and other debris from aluminum beverage container (UBC) scrap or other low-density materials.

• Process is intended to reduce residual contaminant build-up in the recycled alloy, reduce furnace melt loss, and recover other recyclable materials from the aluminum such as lead, copper, paper, plastic, etc.
• The principle involves air separation of lighter materials from heavier free-falling materials. A vibratory feeder is used to transport the material over a high-velocity air knife or curtain. The vibrating action causes finer, heavier materials to migrate to the bottom of the conveyed bed, where they fall through the air curtain and are collected below. Aluminum and lighter materials are blown across into a separation hopper, where the aluminum falls out onto a collection belt. Dust, paper, plastic and other lighter materials are collected in an exhaust system consisting of a cyclone and/or after-filter.
• The concept provides a 95% efficient means of cleaning the aluminum scrap and recovery of contaminants with very low energy consumption and low front-end capital expense.
• Designed to process shredded UBC or whole cans.
