Spiral Conveyor Applications

PE&F builds spirals for diverse food processing and industrial applications. Our spirals are used in the seafood and protein processing industries, in bakeries, in vegetable processing, and pharmaceuticals. Industrial applications include blanching, proofing, chilling, freezing, cooling and curing. PE&F engineers can design a multi-spiral production line that will take your product from proofing or blanching all the way to freezing.

Freezing and Chilling are the most common application for PE&F spirals. A critical component of food preservation, freezing and chilling are responsible for the widespread development of centralized food production and global distribution. Seafood, poultry, beef, fruits & vegetables, and dessert producers all rely upon careful and efficient freezing practices for their production goals. Our customers provide our team at PE&F with a few simple measurements, and we can respond quickly with a customized spiral conveyor that suits their manufacturing needs. We prefer mechanical refrigeration techniques to cryogenic due to the low operational costs and nonexistent product contamination.

Proofing is the climate controlled process which allows the dough to rise before entering the oven. Within the larger process called fermentation, the yeast is activated and is allowed to leaven the dough. This must be done before the extreme temperatures alter the yeast’s chemical composition. The proofing process must be precisely timed and climate-controlled in order to prevent structural failures within the bread, caused by over or under leavening. Spiral conveyor systems provide both the timing and atmosphere needed for large-scale bakery production. Proofing is most often associated with the baking industry.

Curing is frequently used in the process of manufacturing pharmaceuticals. Curing allows a product to reach a desired consistency or texture by exposing it to the appropriate atmosphere. Without this step, many products would be very difficult to package, store, or transport safely while maintaining structural integrity. Most businesses devote precious labor hours to removing the nearly finished product from the conveyor for curing, and then reintroducing it once the delay is finished; such resources could be easily preserved with the introduction of a custom-fit spiral curing component.
