The Tri-Pak Air Curtain Dryer is a forced-air drying system designed to remove surface moisture from produce after washing operations. Using high-volume propeller fans mounted in a stainless steel overhead frame, the system directs a powerful curtain of air across the product as it passes through, rapidly accelerating surface drying before waxing, labeling, or packing.

The standard air curtain dryer consists of two large-diameter Dayton propeller fans — 42" to 48" diameter depending on conveyor width — each with a dedicated 2 HP three-phase motor and belt drive reduction. Both fans are mounted in a common stainless steel frame positioned overhead, with a stainless steel expanded metal guard covering the full frame for operator safety. Multiple dryer units can be staged in series to extend the drying zone and achieve thorough surface moisture removal at higher line speeds.

For operations requiring extended drying capacity, a 40-foot containerized dehydrating chamber is also available. Built from a standard ISC shipping container with stainless steel clad interior and insulated walls, this unit incorporates a four-zone heated air system with four Modine 400,000 BTU indirect-fired heater units, 5 HP forward-curve blowers with variable speed drives, and two powered tube-axial roof ventilators for moisture exhaust. Dickson touch screen temperature and humidity displays monitor conditions throughout the chamber.

Whether used as an inline overhead air curtain or a full-capacity drying tunnel, Tri-Pak drying equipment provides effective, configurable moisture removal for fresh produce operations requiring reliable surface drying in continuous-throughput packing line environments.
