铝质易拉罐导热良好、不锈蚀，又便于连成整体，可以利用制作干燥器和热水器。一、太阳能香菇干燥器本干燥器（图1）是直接以空气为传热流体的渗透型集热器。每台年（集中于冬、春季）可干燥鲜香菇183万公斤，相当于木柴供热干燥器烘238万公斤的柴耗。制作：将易拉罐打通（留茬 Aluminum cans good thermal conductivity, corrosion-free, and easy to even into the whole, you can use the production of dryers and water heaters. First, the solar mushroom dryer The dryer (Figure 1) is directly to the air as the heat transfer fluid permeable collector. Each year (concentrated in winter and spring) can dry 1.83 million kilograms of fresh shiitake mushrooms, the equivalent of firewood dryer 2.38 million kilograms of burning wood consumption. Production: get through cans (stubble
