Title:
METHOD FOR EFFICIENT AND EFFECTIVE DRYING
Document Type and Number:
WIPO Patent Application WO/2019/014750
Kind Code:
A1
Abstract:
A drying device including a container (25) where the product to be dried (22) is placed within said container. An inlet (10) allows the ambient air to enter, through an inlet valve (15) and a first conduit (20), inside the container (25) wherein the inlet valve (15) restricts the amount of air flowing depending on its percentage of opening. The incoming air and product (22) are heated by a heat exchanger (45) which causes evaporation of the moisture from the product. The working fluid, an air/vapor mixture, is sucked up from the container (25) through a second conduit (30) by a compressor (35) which pressurizes the working fluid to be delivered to the heat exchanger (45) through a third conduit (40). This pressurization step raises the working fluid temperature. Inside the heat exchanger (45), the pressurized and hot fluid transfers back its thermal energy to the product (22) thus cooling down the working fluid and generating water condensation. The working fluid leaves the heat exchanger (45) through a fourth conduit (50) to an outlet valve (55) where the pressure drops to the ambient pressure. Finally, the working fluid exits through a fifth outlet (60). The container (25) can be double walled for dripping control.
