Hydro-Cooler (loose produce)

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.

Features

Quickly reduces core temperature of produce which extends shelf-life and preserves flavor and appearance.
Produce immersion* improves heat transfer efficiency. A sensor is available to detect water level.
Variable speed controlled conveyor allows you to control cooling time.
Stainless steel tank – strong and cleanable.
Rotary Filter Unit* Provides continuous water filtration to prevent blockages.
Gooseneck elevator* gently delivers produce to next stage. Extensions available*.
Drain valves (two) allow the tank to be drained of water. Automatic valves available*.
Access hatches* for full access for maintenance and cleaning.
The water spray system cools produce and maintains optimum temperature.
Integrated coils mean no need for an external heat exchanger.
The modular belt on the conveyor allows water to fall through to the base of the tank for recycling. Cleanable and serviceable.
The integrated tank allows semi-immersed cooling.
Equipment automation with touch – screen smart, easy equipment control.
Variable speed controlled elevator and pump which allows full equipment control.
Gravity-aided belt tensioning reduces belt wear.
