Evaporator wiht flange connection structure, evaporation chamber with ribs spiral groove around the welded structure to enhance inner strength, and the wall thickness through rigorous testing to detect sound waves, uniform wall thickness, and to ensure the sustainable use of the evaporator is not deformed. With the horizontal motional design, the wear-out of the system can be reduced, and gas leak avoided, it is also maintaining good precision and intensity wiht high grade 304 stainless steel together automatic argon-arc welding. Features: 1) Daily output: 500kg/24h 2) Capability: Good 3) Texture: Excellent
