Rotary fans are designed in conical shape ın order to distribute the air inside the dryer homogeneously and the body of the fans is made of galvanized iron sheet. It is possible to add extra row for rotary fans to decrease the cycle time and make two cycles/day. There are air exit channels on top of the circulator fans which are adjustable. There is turbo system inside the rotary fans. The aluminium propeller of the turbo system is directly joined to the motor and it blows the air inside the body of the rotary fan by rotating in a high revolution. The air which goes through the fan is distributed inside the dryer by means of air exit ducts. By transmitter it’s possible to control humidity and temperature. There is a hydraulic door opening system. It lifts up the doors and moves the door to the demanded direction. It is propelled with a hydraulic hand pump. For the sake of easy movement it moves with whells. Insulation panels forms the wall and roof of the dryer.
