Most dryers on the market today are based on the single principle of using heated air. This principle is fairly efficient when ambient air is relatively dry. However, when ambient air has high relative humidity such as found in tropical countries, to maintain drying efficiency the temperature must be increased. This is contrary to the requirement for higher quality products which must be dried at as low a temperature as possible.

The proprietary technology used in Daika Dryers™ has resolved those problems by an advanced drying cycle in which the air is dehumidified before it is heated. The two functions are realized by a heat pipe enhanced, high efficiency heat pump cycle which includes:

A dehumidifier section with an evaporator enhanced by a Heat Pipe Battery (an invention of Heat Pipe Technology, Inc., an affiliate of ADS. Patents #5,404,938, #5,845,702).   A heating section that uses the heat from the heat pump cycle to heat the drying bin. The DK IC Series also use the heat recovered from the engine cooling and exhaust.

Due to the dehumidification function, the efficiency of Daika Dryers™ is maximized, even when outdoor relative humidity is 100%. At the same time, the drying air is kept at a relatively low temperature to insure the high quality of the products. This results in substantial economy in energy and allows for shorter drying time.
