1, Strong Structure:

Machine is made of high-strength square tubes and thick steel plates.

Machine's all six panels are through heat treatment to release welding stress, so that panels cannot deform under high temperature.

After heat treatment, all panels are processed by sand blasting treatment to remove rust, then first painting and final painting is done to keep machine anti-corrosion.

2, Steam System:

Use three ball valves to control steam, saving 50% steam comparing to traditional one main valve system.

Steaming is controlled by Timer and three Germen electrical gauge switches, with a safty valve to save from gauge malfuncton situation.
