Post Harvest - Salad & Vegetable Fogging & Crop Hydration
Tru-fog Crop Hydration System
A unique process developed by Pendred Humidification working closely with international produce and salad growers, packers, processors and shippers.
Turns your cold store into a conditioning room by filling the atmosphere with a light but visible Tru-fog made up of minute droplets (<3 microns) of purified water suspended in the atmosphere enables living produce deprived of its root system to hydrate.
High humidity fogging goes beyond normal humidification. Used in support of existing high humidity cooling systems or agricultural humidification systems are already in use, it also makes traditional DX refrigeration more efficient and less costly to run.
Maximise pick weight, quality & shelf life
<3 micron water droplets, small enough to be absorbed naturally into the leaves and bodies and salad and vegetable products ‘without wetting’, very beneficial during temperature pull down to remove field heat and or longer term storage.
Only UltraSonic nebulisation can produce the required amount of <3-micron fog. Agricultural humidification systems using compressed air and water, spinning discs, or high-pressure water produce droplets of >20 microns and are only designed to boost humidity to neutralise the drying effect of refrigerated air.
Don’t be misled by agricultural systems, sometimes referred to as Fogging systems. These do not produce the amount of <5 micron droplets or Tru-fog required to re-hydrate crops and also tend to wet the crop and floor.
Tru-fog will re-hydrate crops harvested in dry weather or delivered with less than their maximum level of moisture. Only a few hours in our Tru-fog environment will see product re-conditioned and up to maximum pick weight, naturally and ‘as nature intended’.
The Benefits
-
Crop re-conditioning after harvest in dry weather.
-
Produce re-conditioning after transport.
-
Extended storage time through natural hydration.
-
Improved efficiency of traditional DX cooling systems.
-
Reduced energy costs through the adiabatic effect (evaporative cooling).
-
Visible. Your customers will see and understand the benefits.
