The objective of the invention is to provide an adhesion-prevention plate used for a vacuum film-forming device, a manufacturing method of the plate, a vacuum film-forming device adopting the adhesion-prevention plate and a vacuum film forming method, wherein the adhesion-prevention plate has good stripping preventing effects of a film forming material in a repeated evaporation circumstances. The adhesion-prevention plate is used for preventing adhesion of the film forming material to an unneeded position in the vacuum film-forming device, is made of aluminum, and comprises a surface of a concave-convex structure having concave parts with an average opening diameter being 0.01-9 [mu]m. A plurality of convex parts having an average height of 30-1000 [mu]m are arranged on the surface. The average density of the convex parts is higher than 10/10 mm<2>. The ratio of the bottom area of the convex parts is larger than 90% in a square area having a size of 10 mm.

The invention discloses a high-efficiency energy-saving environment-friendly smokeless steamer which comprises a steamer body, a thermal insulation cover and a strong-thermal seat. The steamer body comprises a main steamer and an auxiliary steamer, the main steamer and the auxiliary steamer form a strong-thermal interlayer, the main steamer comprises a main steamer opening, a main steamer side and a main steamer bottom, and the auxiliary steamer arranged outside the main steamer comprises an upper steamer side, a strong-thermal net, a lower steamer side, a strong-thermal bottom and steamer handles. The upper end of the upper steamer side is tightly attached to the upper end of the main steamer side, and the bottom end of the upper steamer side is connected with the upper end of the lower steamer side. The upper end of the lower steamer side is connected with the bottom end of the upper steamer side, and the lower end of the lower steamer side is connected with the edge of the strong-thermal bottom. The inner side of the lower steamer side and the outer side of the main steamer side form an attachment interlayer, the strong-thermal net is arranged on the inner side of the lower steamer side, and the strong-thermal bottom is provided with a plurality of tiny through holes or concave holes and attached with the main steamer bottom. The thermal-insulation cover comprises a pressure reduction valve, a handle, a condensation ring, a thermal insulation layer, a seal side and a view hole. The energy-saving seat comprises an outer sleeve, a vent hole, a strong-thermal ring and a strong-thermal groove.
