Abstract

An efficient vacuum low-temperature hot air drying device comprises a closed drying cabinet. A hot air generation cavity of a hot air generator is formed in the drying cabinet. A hot air inlet allowing hot air to be blown into the drying cabinet is formed in the lower portion of the hot air generation cavity, a hot air outlet for sucking backflow air in the drying cabinet is formed in the upper portion of the hot air generation cavity, and the drying cabinet and the hot air generation cavity form a hot air circulation flow pass through the hot air inlet and the hot air outlet. A moisture discharge outlet connected with an exhaust pipeline is formed in the top or sidewall of the drying cabinet. A vacuum opening communicated with an external vacuum pump is formed in the upper top or sidewall upper portion of the drying cabinet. By the efficient vacuum low-temperature hot air drying device, edible mushrooms can shrink in the same proportion during drying, so that the edible mushrooms can be kept stable in shape, and energy consumption can be reduced.
