The explosion-proof bottle cap for glass bottle consists of metal sheet cap, sealing plastic washer, explosion-proof metal cap and safety pull sheet. the metal sheet cap has hemmed hole riveted with the explosion-proof metal cap, which has pressure strength determined by the hemming strength of said hole and its tensile strength. The metal sheet cap is pressed to bottle mouth, and in case that the pressure inside bottle is raised to certain value below the bottle strength, the explosion-proof metal cap opens automatically to avoid bottle explosion with the safety pull sheet pulling the explosion-proof metal cap to avoid flying away.

Method for extracting linseed oil by cold pressing with salt-water wetting

Номер: CN104212629A
Автор: JIAO JIANWEI, JIA SHANGJUN, YIN ZHENXIONG
Принадлежит:

The invention discloses a method for extracting linseed oil by cold pressing with salt-water wetting and belongs to the fields of food and food processing. The method comprises the following steps: naturally drying linseeds, adding salt water to stir and wet the linseeds, then carrying out low-temperature pressing, and centrifugating at high speed to obtain pure-natural linseed oil. The method disclosed by the invention is improved on the basis of the traditional method for extracting the linseed oil by cold pressing, and has the beneficial effects that the dry linseeds are wet by salt water, the tissue structures of membranes on the surfaces of the linseeds are changed, and then low-temperature pressing is carried out, so that not only is no damage to the original components well maintained, but also the oil yield of the linseed oil is greatly increased (increased by 29.44% compared with that of the traditional cold-pressing process), and the used amount of an organic solvent used in secondary ...
