The invention discloses a height-adjustable energy-saving type
drying room. The height-adjustable energy-saving type
drying room comprises a
drying room body, a conveying device and a steam drying
system, wherein the conveying device is arranged inside the drying room body; the steam drying
system comprises at least one air source
heat pump arranged above the drying room body; air inlets of the
air source heat pumps communicate with the interior of the drying room body; air outlets of the
air source heat pumps communicate with a circulating air duct through a circulating fan; the circulating air duct comprises an air
inlet channel and at least one air outlet channel, wherein the air
inlet channel communicates with an air outlet of the circulating fan, and the air outlet channels communicate with the air
inlet channel; the air outlet channels are arranged among annular conveying chain nets; a plurality of exhaust holes are uniformly distributed in the upper plate surface of each air outlet channel; the cross section of each of the air inlet channel and the air outlet channels is rectangular; and the side surface of each of the air inlet channel and the air outlet channels is in a
right triangle shape. The height-adjustable energy-saving type drying room has the advantages that the height is adjustable, the operation is stable, air distribution is uniform, and air is not wasted and is all used for air circulation.
