<p>PURPOSE: To rapidly reduce the weight of raw Lentinus edodes Sing. on a mushroom bed with a dehumidified air stream controlled to a suitable temperature quickly after collection, efficiently prolong the period for retaining the freshness of the raw Lentinus edodes Sing. and reduce waste due to deterioration in merchandise value. CONSTITUTION: The weight of raw Lentinus edodes Sing. is reduced with an air stream, controlled to 10-25 deg.C temperature and dehumidified at 3-4 m/sec quickly after collection so as to provide the weight loss ratio with at least 15-30% and the period for retaining the freshness of the raw Lentinus edodes Sing. in the mushroom bed is prolonged. Furthermore, the apparatus for prolonging the period for retaining the freshness of the Lentinus edodes Sing. in the mushroom bed is obtained from a cooling and dehumidifying system comprising a drying chamber 10 for arranging the raw Lentinus edodes Sing., a refrigerant evaporator 21 for cooling and dehumidifying air at a high humidity returned from the drying chamber, a refrigerant condenser 22 for heating the cooled and dehumidified air to a suitable temperature, an outdoor refrigerant condenser 26 for discharging the energy in a larger quantity than that required for heating the air to a suitable temperature to the open air, a refrigerant compressor 23 and a refrigerant pipe 24 for connecting these devices as main constituent elements and an air blasting system for feeding the air at the suitable temperature and suitable humidity controlled with the cooling and dehumidifying system into the drying chamber 10 and returning the air to the cooling and dehumidifying system.</p> |
