1) Combining wet-injection, setting and drying, available regulate the time as you want, besides, keep hot circulate inside working chamber so that the temperature inside can be stable with less heat loss, thus, the energy consumption can be reduced obviously2) It will only take 8-10min to finish setting with about 2.5kg diesel oil consumption per hour, if the unit price is 6.8yuan/kg, the total cost is just 17yuan, and if the working efficiency of setting is 3500 pairs of socks per hour, the setting cost per pair is just 0.5Yuan.3) In the box installs leads the wind net. The patent design, leads the wind net addition with the exotic material manufacture in the box the work room crown, can cause in the work room the wind sped and the steam cycle in evener.4) Recuperation. This is additional part, may cause in combustion chambers afterheat back flow to the work room base, cause in the work room warm to be quicker, to be evener.
