The invention discloses a workpiece electromagnetic incremental forming device provided with profile-followed arrangement coils, and further discloses a workpiece electromagnetic incremental forming method. The workpiece electromagnetic incremental forming device comprises a supporting frame, a mould, a plate, plate clamping assemblies for fixedly clamping the plate, and a driving piece for driving the mould to move so as to conduct stretch forming on the plate, and further comprises the multiple profile-followed arrangement coils. The plate clamping assemblies are arranged on the supporting frame; the plate is fixedly clamped between the plate clamping assemblies; the driving piece is connected with the mould; the profile-followed arrangement coils are arranged on the periphery of the surface of the plate subjected to stretch forming by the mould in a surrounding mode; and all the profile-followed arrangement coils are arranged on layers of different heights above the plate correspondingly. The workpiece electromagnetic incremental forming method comprises the steps of plate fixing, stretch forming of the plate, electromagnetic forming through the profile-followed arrangement coils and the like, and the plate and the mould are attached by repeatedly executing plate stretch forming and electromagnetic forming. The workpiece electromagnetic incremental forming device and methodhave the advantages of being high in forming precision, good in forming quality, high in efficiency, high in utilization rate of discharge energy, low in equipment energy demand and the like.

The invention discloses an egg coating preservative which takes oxyethlene higher aliphatic alcohol as a main coating forming material and takes absolute ethyl alcohol, polysorbate 80, glycerol and palm oil as auxiliary materials. The invention also discloses a preparation method of the egg coating preservative. The egg coating preservative has the characteristics of being good in coating forming property and moisture retention, ensuring that the appearance of a coated product is beautiful, and the like, can effectively prevent the invasion of microorganisms and the moisture loss of the egg product, can adjust gas compositions to restrain an egg white thinning effect, has a good preservation effect, and has effects which are obviously superior to those of common egg coating preservatives.

The present invention relates to an apparatus for preparing the following foods (production) continuously, the foods is made by packaging inner material composed of foods such as stuffing or fruit jam etc. by tegmen material composed of foods blank such as bread etc. A blank pressing component is formed integratedly on the peripheral of a nozzle component for extruding inner material, the peripheral part of the tegmen material locating on the upper surface of a carrying component with hatch is clipped between the blank pressing component and the carrying component, and the upper opening of the bowl-shaped tegmen material is closed by the nozzle component and the blank pressing component, so as to prevent the inner material from leaking from the upper opening by maintaining the clipping state when ejecting the inner material into the inner of the tegmen material, and to prevent inner material from leaking to manufacture no good production when sealing the peripheral of the tegmen material. In addition, due to prevent inner material from polluting food manufacture device, it is able to prepare foods continuously without stop the running of the device.

The invention discloses an electromagnetic incremental forming method. The electromagnetic incremental forming method adopts a hierarchical manner to realize layer-by-layer forming from the bottom up; only a local position is formed during each forming, so that a die fittingness range is expanded continually till the forming of a whole workpiece is completed; then shaping is realized to improve the forming quality of a sheet; finally, a housing part which is uniform in thickness distribution and good in surface quality is obtained. Shaping can be realized through an orthotic coil or the orthotic coil and a magnet collector. According to the method, after hierarchical forming, the fluidity of sheets is improved, and a local thinning phenomenon is prevented; meanwhile, a sheet waving phenomenon, which is caused by instability wrinkling, in an electromagnetic incremental forming process can be prevented, so that the electromagnetic incremental forming precision is improved; as the fluidity of the sheets is improved after hierarchical forming and the local thinning phenomenon is prevented, the forming of housing parts with uniform wall thickness is facilitated.
