Dehydration equipment options

There is a range of options available for commercial dehydration projects, including batch drying, freeze drying, microwave drying, and vacuum drying. However, Agridry Systems focuses on batch drying, as it is the most versatile and widely used method. For specialized applications, alternative methods can be used.

Vented dryers

These are commonly referred to as “heat and dump” dryers, as they introduce heated fresh air, which displaces moist air that is then discharged. During the drying cycle, most of the air in the room circulates through the product, with a controller determining the percentage of fresh air to be introduced for maximum efficiency. A heat pump can be used as the heat source, but electric elements are a lower-cost alternative, suitable for short seasonal applications. Agridry Systems uses a heat exchanger to capture the heat leaving with the moist air, pre-warming the incoming ambient air. However, the lowest humidity achievable is limited by location and climatic conditions, with coastal or tropical locations during high humidity periods posing a challenge. The lowest humidity achievable with this method may not be suitable for some products.

Closed cycle heat pump dryers

On the other hand, Agridry Systems’ closed cycle heat pump dryers lead the industry in terms of efficiency and performance. Drying air streams lower that 10% RH are achievable. The 500kg/day modular unit can be transported by truck or within a shipping container, positioned in a 1800mm wide opening in the customer’s drying room, and moved into place using a forklift.

As an alternative, we can supply the dehydrator built into a new insulated shipping container.

These units require three-phase 40A electrical connection and a drain.
