Title:
NEGATIVE-PRESSURE CONTINUOUS GRAIN DRYER WITH BUILT-IN HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/006672
Kind Code:
A1
Abstract:
A negative-pressure continuous grain dryer with a built-in heating device (3) comprises a dryer bin (2), heating devices (3), and a centrifugal fan (9). Several levels of the heating devices (3) are disposed from top to bottom in the dryer bin (2). A grain mixing device (5) is provided below the heating device (3) at each level. Outside the bin, an auxiliary heating device (6) and a natural air inlet (7) are provided in correspondence with the heating device (3) at each level. The auxiliary heating device (6) and the natural air inlet (7) communicate with the grains and the respective heating device (3) in the dryer bin (2) through a perforated baffle plate (4). The centrifugal fan (9) communicates with each of moisture exhaust vents (11) at each level through an air duct (10). The dryer can implement drying of grains in an "intermittent" mode, a "gradient" mode, a "balanced" mode, a "uniform" mode, and a "continuous" mode. There is a large range of applicable heat source carriers for the heating devices (3).
