Main feature:
1.large rate of starting hole, adopting concave protruding hole to strengthen the intensity of roller. The area of starting hole of 1/4 roller reach 0.2m2,the rate of starting hole reach 34%,Through this design to low the air resistance and the cost of running of machine.
2. Reasonable structure .Roller adopts cw&anti-cw turn. Cloth is taken to upper left or right corner of the roller. Lie at an angle of 45 degree with lower left corner, drop in the form of parabola. Hot air enters the roller from middle upper part, exit from middle lower part, having the biggest area and the longest time of heating exchange. High Utilization ratio of heating energy.
3. Roller is made of stainless steel. Outer is power coat. Heater is made of copper. The decoration looks well.
4. Easy structure, easy to operate, high efficiency, low noise, convenient to maintain.
