The invention discloses an all-weather
solar dryer. The part of an upper outlet of a
solar heat collector is connected with the upper end of a
water storage tank through a pipeline, a lower port of the
solar heat collector is communicated with the lower end of the
water storage tank via an auxiliary water pump, a furnace body is a cavity with one side open, a
heat exchanger is arranged at the open position of one side of the furnace body, one end of the
heat exchanger is communicated with the bottom of the
water storage tank through a pipeline, the other end of the
heat exchanger is communicated with the upper-end liquid level of the
water storage tank through a main water pump, a main
air blower is arranged in the furnace body and close to the inner side of the heat exchanger, a feed bin is arranged at the top end of the furnace body, a screen is arranged at the bottom of the feed bin, the feed bin and the furnace body are communicated via the screen, and the inlet end and the outlet end of an auxiliary
air blower are communicated with an upper port of the feed bin and the bottom of the
water storage tank respectively through pipelines. The all-weather
solar dryer is an auxiliary electric heater, and can be ensured to be normally used in weather without sunshine.
