The present invention relates to a normal temperature and pressure food drying apparatus. A blower exhausts the air inside a drying room and the exhausted air is further heated to a first temperature by a first thermostat. The exhausted air with the first temperature passes through a dehumidifier with a second temperature. Since the second temperature is lower than the first temperature, a temperature difference between the first and second temperatures makes the first temperature of the exhausted air is decreased to a dew point and then a vaporous water included in the exhausted air becomes to a liquid. The liquid is drained through a drainage hole. At the time, an air outputted from the dehumidifier is drier than the exhausted air and then is further heated to a normal temperature to back the drying room. Therefore, the drying room can maintain in the normal temperature and pressure condition and the food can be dried when the dehumidifier takes a moisture out of the food.本發明係一種常溫常壓食品乾燥設備,係以一第一鼓風機將乾燥室的空氣抽出,由第一溫控單元調整其溫度至第一溫度,再通過一個維持在較第一溫度為低的第二溫度的除濕裝置,藉由第一及第二溫度的溫度差使得第一溫度的空氣的溫度下降至露點溫度,將氣體包含的氣態水凝結成液態水自出水口排出;此時,通過該除濕裝置進入該進氣管的空氣變得更乾燥,並由一第二溫控單元調整乾燥溫度至常溫後回送至該乾燥室;如此即可確保該乾燥室內為常溫常壓,且不停透過該除濕裝置除水而更乾燥,讓食品內含水分被強迫釋出,達到乾燥的效果。10‧‧‧本體11、12‧‧‧容置空間20‧‧‧乾燥室21‧‧‧第一出風口22‧‧‧第一進風口30‧‧‧第一循環氣管31‧‧‧進氣管32‧‧‧出氣管40‧‧‧第一鼓風機50‧‧‧第一溫控單元51‧‧‧第二溫控單元60‧‧‧除濕裝置61‧‧‧容器62‧‧‧低溫氣體通道63‧‧‧出水口
