Key Technology Auto Dryer for fresh-cut produce

Key Technology has redesigned its Auto Dryer, adjusting the controls, motor and structure. Like the original dryer, it removes surface water from fresh-cut produce and vegetables, but it also enables continuous line flow.

The dryer achieves fully automated, uninterrupted loading and unloading. Compared to batch drying, the dryer is claimed to increase throughput in smaller floor space while reducing labour and improving worker safety and sanitation.

The dryer can handle 500-1360 kg of product per hour per drum, meaning the four-drum model can handle up to 2000 kg/h when drying lightweight products and up to 5443 kg/h when handling heavier products.

The dryer may reduce product damage and maximise drying efficiency by loading a constant flow of product into dryer drums via a spiral layering method that eliminates product slug. With centrifugal pressure, the unique spiral layering achieves uniform drying while reducing wear on mechanical parts.

The redesigned hood system enables access to the drum for cleaning. The stainless steel dryer is designed to food safety standards to minimise cracks and crevices that can harbour bacteria. The control system monitors the condition of the drum and automatically adjusts the spin speed if an out-of-balance condition is detected, reducing wear.

Key offers an optional package with the dryer that includes a dual-level storage belt, dewatering feed shaker and discharge belt conveyor.

Addressing fresh-cut processors’ need to relocate their production lines, the company designed the dryer so it can be moved with a forklift and the configuration of the system can be modified in the field.
