Cooker and Chiller Discharge Conveyors

These conveyors carry pet food from a steam cooker and a chiller toward bagging. Some products go straight from chilling to bagging, while others need an extra slicing step that sits at a higher elevation. Instead of building two lines, or settling on one height that suited neither, I designed the conveyors to work in two defined configurations. The incline raises for the slicing operation when a recipe calls for it and lowers when it doesn’t, and both configurations are fully drawn.

Adjustable equipment in a food plant tends to fail in a predictable way. It ends up approximately positioned, then less so, until nobody trusts it and it gets left in one place. To prevent that, I added latching assemblies with a pinning bracket and locating tabs, so the conveyor goes to a defined position and gets pinned there. Changeover becomes a repeatable operation instead of a judgment call, and the transfer into the next machine is the same every time. We also reused scraper blades from an earlier job, since they already worked well in the same duty.

The conveyors also have to be removed from the area regularly so they, and the steam cooker in particular, can be properly cleaned. Everything that can trap product comes off, including the side guides, wear bars, rollers, and the belt itself. Each of those meant design decisions about fasteners, captive hardware, clearances, and the order things come apart in, and together they’re the difference between a five minute strip-down and a job nobody wants to do.

In a pet food plant, cleaning isn’t just a constraint on the design; it’s one of the things the design is for. Equipment that fights being taken apart ends up cleaned around instead of cleaned.
