Product Description
Wyma Hydro-Coolers quickly reduce the core temperature of fresh produce, extending shelf life while preserving flavor and appearance. Water is sprayed over a heat exchanger which is cooled to several degrees below freezing by refrigerant.
As the water passes over the heat exchanger, the water cools to a userset temperature.
Cooled water then floods down onto produce. Water is collected in a tank at the base of the Hydro-Cooler for recycling. Produce travels by conveyor through the Hydro-Cooler.
Produce can be partially or fully submerged in water. An outfeed elevator gently carries produce to the next stage in your line.
Features
- Quickly reduces core temperature of produce, extending shelf life and preserving flavor and appearance.
- Produce immersion improves heat transfer efficiency.
- Variable speed-controlled conveyor allows for controlled cooling time.
- Gooseneck elevator gently delivers produce to next stage.
- Modular belt on conveyor allows water to fall through to the base of the tank for recycling.

Wyma Mega-Polisher
Wyma's Mega-Polisher is the largest vegetable polishing system in the world. It consists of two Vege-Polisher™ machines linked together.

Wyma Absorbent Drying Roller
Absorbent Drying Rollers remove excess moisture from the surface of fresh produce, reducing the risk of bacterial growth. The roller's porous surface draws in moisture as produce travels along the bed.

Large Potato Packaging Line
With this example of a large Potato Packing Line with a capacity of 90-ton/hour, Wyma illustrates the scale and complexity required to process and handle large volumes of potatoes or comparable root vegetables.

Small line to pack potatoes
In this example of a small line to pack potatoes (5 ton per hour), produce can be received onto an Elevator where they are fed into a Horizontal Debris Remover, to remove loose dirt, vine, and other debris.
