Cooling Conveyor

Written by Administrator | 02 February 2012

Arintha system Belting that allows air to circulate freely around and under parts, is an excellent way to promote cooling. Belting can be used alone, or with additional cooling aids such as blown ambient air or chilled air. Choices include Modular belt, Wire Mesh belting. If you need to cool an extrusion or part quickly, a water spray can sometimes be the perfect choice. This application uses three water sprayers to spray a fine mist of water down onto hot extrusions as they pass underneath. Water drains off through a wire mesh belt, into a stainless steel pan below. To allow the extrusions to be packed immediately, two air knives blow off residual water.

A. Water Cooling

Arintha system Water cooling conveyors are an excellent way to cool thick walled parts as they are being transferred to another conveyor or work station. Customized, flat-to-incline conveyors and water holding tanks provide a soft landing and maximum cooling. Units are available in a wide choice of widths and lengths.

This submersible conveyor has a cover with a cylinder activated, hinged door at the in-feed end. Upon a signal, by a robot (or other device), the in-feed door opens, parts are allowed to enter the water, then the door closes, holding the parts under water while the in-tank conveyor moves them to the inclined section of the conveyor. The door re-opens for the next parts. An indexing option is also available. Tank and conveyor specifications are the same as those listed below for standard Submersible Conveyor.

B. Blowing ambient air

Blowing ambient air over warm parts can be a relatively inexpensive way to help cool warm parts on their way to packing or assembly operations. Cooling chambers can be placed on flat or incline conveyors. Indexing the conveyor belt can help to maximize time in the cooling chamber. Blowers can be variable or fixed speed.

C. Chilled air cooling

Chilled air cooling is an excellent choice when parts need to be thoroughly cooled. Standard chilled air cooling units include a blower and coils mounted in an enclosure over the conveyor belt. Chilled water is provided by the customer’s chiller or tower. Cooling chambers can be placed on flat or incline conveyors. Indexing the conveyor belt can help to maximize time in the cooling chamber. Blowers can be variable or fixed speed. While chilled air cooling units require access to a chiller or a tower for chilled water, self-contained units requires nothing other than a 110V outlet. Self contained units can provide quick-cool, post-mold cooling to as low as 40 to 45 degrees F. (depending upon ambient plant air and the temperature of the parts). Simple set up requires no plumbing.
