Hydro‑Cooler for loose produce

Our Hydro-Coolers quickly reduce the core temperature of fresh produce to extend shelf-life.

Description

Wyma Hydro-Coolers quickly reduce the core temperature of fresh produce, extending shelf-life while preserving flavour 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 user-set temperature. Cooled water then floods down onto produce. Water is collected in a tank at the base of the Hydro-Cooler for recycling.

We have two types of Hydro-Cooler that can handle loose produce:

Hydro-Cooler for loose produce: 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. Suitable for carrots, potatoes, parsnips, etc.

Flow-through Hydro-Cooler for small plastic bins or loose produce: Bins or loose produce travel by conveyor through the Hydro-Cooler. Produce is sprayed with cooled water. This model is commonly used for broccoli, asparagus, cherries, radishes and beetroot (beet).

At Wyma, we have an in-depth understanding of the post-harvest handling and cooling processes. Dwell time, equipment and refrigeration specifications are tailored to meet your needs.
