#CMT# #/CMT# The device has a black plate (5) or lacquer for absorbing maximum sunlight. A belt conveyer (1) is placed under the black plate, where heat recovered by the plate is used for drying products. An insulation system includes a glass plate (73) or green house placed at the top of the black plate and thermal insulation walls (6). A condensate evacuation system includes an inclined sheet and a recovery channel placed outside of a confined space (4). A suction system includes vacuum fans and pipes for evacuating the air below the black plate. #CMT#USE : #/CMT# Device for improving drying efficiency by using solar closed collector in solar water heater. #CMT#ADVANTAGE : #/CMT# The glass plate isolates the heat from the plate with respect to a less hot environment. The green house is placed at the top of the black plate, so as to improve thermal insulation effect. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front sectional view of a closed solar drying collector. 1 : Belt conveyor 4 : Confined space 5 : Black plate 6 : Thermal insulation walls 73 : Glass plate. |
