▎ 摘　　要

NOVELTY - The device has a heating furnace body whose two inner wall sides are provided with a first supporting plate (101) and a second supporting plate (102) that are oppositely arranged with each other. The heating furnace body is provided with a heating component for heating and a cooling component (200) to accelerate cooling. The cooling component is provided with a heat partition cooling piece that slidably connected on the first supporting plate and the second supporting plate. The heat partition cooling piece is connected with a cooling device (202) and partitions a space between the first supporting plate and the second supporting plate. The heating component is fixed below the first supporting plate and the second supporting plate. USE - Graphene heating device for processing fruit and vegetable drying food. ADVANTAGE - The heat partition cooling piece partitions the space between the first supporting plate and the second supporting plate to improve cooling speed. The device realizes rapid heating and cooling.
