Life would be lot easier for conveyor manufacturers if every application involved handling temperate products. Reality, however, is quite different – many conveying applications involve handling products that are either quite hot or cold. Successfully handling these products without either damaging the equipment or the product requires using conveyors that are specially engineered for the job. This blog looks at the challenges of vertically conveying products at extreme temperatures using continuous bucket elevators and shows how UniTrak tailors its equipment to successfully overcome these hurdles.
Bucket elevators moving cryogenic materials, frozen foods, freeze dried coffee, etc., or which are installed in cold room environments or outdoors, have to deal with low temperature extremes.
Due to the frigid temperatures involved, handling cold temperature products can be particularly challenging as it imposes unique stresses on conveying equipment. The low temperatures can impose significant stresses on conveyor drive assemblies, as well as the equipment frame and lubrication system. Here is how TipTrak™ bucket elevators from UniTrak are engineered to deal with these low temperature challenges:
Moving hot products in a bucket elevator requires that the conveyor be designed to be resistant to the effects of high temperatures. In particular, buckets and drive assembly components which are likely to come into direct contact with hot product must capable of withstanding the high heat transfer which will occur.
For applications involving hot products, TipTrak™ elevators are supplied with rubber beltchains, buckets, and flexible joint strips designed to support high temperature service. TipTrak™ rubber beltchains, buckets and joint strips for high temperature service will support application temperatures up to 200°C (390°F).
A further application requirement to consider when moving hot product through a bucket elevator is whether or not the product temperature should be maintained or lowered. If the former, a fully sealed elevator, such as the TipTrak™ Monocoque model, will help maintain the product temperature as it moves through the elevator. In cases where it is desired to dissipate the heat and cool the product as it transits the elevator, either a TipTrak™ Open Tube or enclosed PEC model with venting would be preferred.
TipTrak™ bucket elevators are available in a range of constructions, configurations, and capacities that will support almost any application.
