Experimental study on microwave drying of letinous edodes


The inner temperature of the mushroom is higher than that of the mushroom surface at the beginning and the end of the drying process (microwave penetration is very strong); the surface temperature of the mushroom surface is always higher than that of the mushroom surface during the hot air drying process (by conduction heat transfer), until the end of the drying process tends to be consistent. The surface temperature (far infrared has a certain penetrability) until the end.
The surface and interior temperatures of the dried mushroom door tend to be stable in the last stage of drying by hot air and far infrared, and the temperature of the dried mushroom door tends to rise after 800 600 4 OO p02.4.3 000. The quality of the dried mushroom door is better than that of the dried mushroom door by microwave drying.
