The cooling process slows down physiological changes, inhibits microbial growth and extends the shelf-life of fresh produce. Efficient cooling techniques ensure that crops maintain their nutritional value and visual appeal, enhancing their marketability and reducing post-harvest losses.

Hydro-Cooler for Loose Produce

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).

Hydro-Cooler for Produce in Bins

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 (loose or in bins). Water is collected in a tank at the base of the Hydro-Cooler for recycling.

Flow-through Hydro-Cooler for large plastic bins: Large bins travel by conveyor through the Hydro-Cooler tank. Produce is sprayed with cooled water. This model is great for bulk bin traceability.

For large tonnages, laned Hydro-Coolers are available (up to three lanes) to save space and cost.
