Dynamic Dryers International can provide you with the best possible and practical fruit and vegetable drying solutions. Our fruit and vegetable dryers/dehydrators are designed for fast and efficient drying. This requires specialised knowledge and engineering skills that we draw from our team of 2 Mechanical and 1 agricultural engineer. Our vegetable and fruit dryers/dehydrators can be used to dry a wide variety of agricultural produce.
Drying agricultural produce extends the shelf life of the processed product. Drying/dehydration removes the water from the product and thus limits the growth of bacteria and enzymes that will cause the product to decay and rot. Dehydrating your produce will also reduce the weight and therefore transport cost of your product. After drying of your product you will be left with a product that is much lighter but still contains all the valuable nutrients and sugars that you started with.
Does your facility make use of steam in other processes such as pasteurisation? Then making use of steam heat exchangers is a great option. These heat exchangers operate at higher temperatures than conventional hot water heat exchangers and will save on cost for not requiring an additional hot-water boiler/kettle.
This system makes use of a corrosion resistant heat exchanger where air is indirectly heated by hot water in a counter flow manner. The hot water is conventionally supplied via boilers which makes use of coal, Macadamia nut shells or other types of biofuel. This system is the most widely used and generally the most cost effective due to the low cost of the fuel.
This alternative heating option burns LPG or natural gas in a direct fired gas burner where Low NOx burners are implemented. Gas is often used in countries where the fuel for the boilers systems is difficult to acquire and gas is more readily available and desired.
Aerodynamics is a vital part in successful drying and flow control optimisation can be incorporated to ensure more homogeneous drying in the product.
Plastic trays simplify the loading and stacking of the product and eliminates strand contamination which is often encountered with open net trays. We also offer open net trays if desired. Our trays are stack upon a corrosive resistant trolley base.
