The utility model discloses a continuous propelling modular sun
drying system and belongs to the field of
solar energy utilization. The
system is characterized in that a feeding channel is arranged above a conveying belt, and a discharging channel is arranged at the
tail part of the conveying belt; hot air material heat exchange cabins are arranged outside the conveying belt at intervals, and high-temperature-resistant fans are arranged in the hot air material heat exchange cabins. A
heat pipe fin heating
assembly is further arranged in the hot air material heat exchange cabin, and fins are arranged above the
heat pipe fin heating
assembly; the total heat exchange
assembly and the
heat pipe fin heating assembly form a circulating
system; the straight-through type
solar heat collector is connected with the heat
pipe fin heating assembly. By combining the characteristics of a direct type
solar drying machine and an indirect type
solar drying machine, not only can
solar energy be directly absorbed to obtain higher
solar energy heat efficiency, but also stable
heat supply can be obtained through the heat storage characteristic of the heat
pipe fin heating assembly, and in addition, through hot air circulation of total heat exchange, the heat efficiency is improved. And the
drying effect can be further improved.
