可能である。In the automatic transport drying apparatus of the present invention,
Consider the amount of water evaporation under the conditions. As a potato sample,
Average sectional diameter: 7cm, length: 20cm, thickness of water film
Only 0.1 mm. Weight of one sweet potato sample w =
534 g, volume v = 411 cmThree, Surface area s = 315c
mTwoTherefore, the surface area per weight a = 0.06 m Two
/ Kg. Therefore, the weight of water content per kg of potato
Quantity mw= 6x10-3Kg of water / kg of sweet potato. Transport process
Assume that the evaporation rate of water from the sweet potato at 90% is 90%
Then, the amount of water evaporation of the whole sweet potato processed per hour Mw= Mxm
wx0.9 = 9.7 kg / h = 9.7 L / h.
Dehumidification capacity of refrigerant compressor of wet machine (3): Possible with 10 L / hour
Becomes The heat of evaporation associated with this evaporation is 5 kg / kg of water.
86 kcal, so that the total potato processed water evaporation heat Qw= 5
86xMw= 5.7 × 10Threekcal / h.
Cooling capacity of medium compressor: 10 × 10Threekcal / hour is enough
It is possible.
