Electrostatic printing apparatus

The application is to be June 24, application number in 2002 the dividing an application for the patent application of " electrostatic printing apparatus and electrostatic printing method " that be 02813205.X, denomination of invention the applying date.

Technical field

The present invention relates to electrostatic printing apparatus and electrostatic printing method, be particularly related to and utilize electrostatic force to make powder printing ink (powder イ Application キ), printed patterns such as literal, figure are printed on the electrostatic equipment and the electrostatic printing method on the surface that is printed thing attached to being printed the thing surface.And the present invention relates to method for making food, particularly used the method for making food of the electrostatic printing apparatus that has utilized electrostatic force.

Background technology

As everyone knows, electrostatic printing apparatus always all is to utilize electrostatic force to make powder printing ink attached to the surface that is printed thing, printed patterns such as literal, figure is printed on the surface that is printed thing.But,, just must be provided with and the identical electrostatic printing apparatus of use number of colors to being printed under the situation that thing carries out multiple color printing because in the past electrostatic printing apparatus can only print with a kind of powder printing ink of color.

When Figure 41 carries out the printing of 3 looks for use electrostatic printing apparatus always, the longitudinal sectional drawing that device constitutes.In example shown in Figure 41, at first, in electrostatic printing apparatus 500a, finish after the printing of the 1st kind of color, be transplanted on next electrostatic printing apparatus 500b, in this electrostatic printing apparatus 500b, carry out the printing of the 2nd kind of color being loaded with the pallet 550 that is printed thing 1.Then, in electrostatic printing apparatus 500b, advance to finish after the printing of the 2nd kind of color pallet 550 to be transplanted on next electrostatic printing apparatus 500c, in this electrostatic printing apparatus 500c, carry out the printing of the 3rd kind of color.Like this, using electrostatic printing apparatus always to carry out under the polychrome situation a plurality of electrostatic printing apparatus being set, and in each electrostatic equipment, carrying out the presswork of each color.

As mentioned above, using electrostatic printing apparatus always to carry out under the polychrome situation, must be provided with and use the suitable electrostatic printing apparatus of number of colors, thereby need the device space that is provided with of broad, be used to carry out polychrome cost and also therefore become very high.

And, in the time will being loaded with the pallet that is printed thing and being transplanted on next electrostatic printing apparatus, the position and silk screen (screen) dislocation of pallet also can take place, factor affecting such as the vibrations during owing to handover, impact, the phenomenon that the position that is printed thing in the pallet is departed from.In this case, since also different according to its printing position of different colors, therefore, can't carry out correct and beautiful printing to being printed thing.

Figure 42 is the schematic diagram of electrostatic printing apparatus structure always.Electrostatic printing apparatus always comprises the loading hopper (hopper) 640 that is configured in the template silk screen (stencil screen) 610 that is printed thing 600 tops, the rotating brush 620 on the silk screen 610, supplies with powder printing ink 630 to rotating brush 620.In silk screen, printed patterns such as literal and figure are formed by mesh net 611.

The powder printing ink 630 that is provided by loading hopper 640 is expressed into the below by brushing 620 rotation from the mesh net 611 of silk screen 610.Apply dc high voltage by dc source DC being printed between thing 600 and the silk screen 610, make to be printed between thing 600 and the silk screen 610 to produce electrostatic field.By the mesh net and by charged powder printing ink, in electrostatic field to as counterelectrode (Dui Electricity Very) the thing 600 that is printed advance always, be attached to the surface that is printed thing 600.Like this, printed patterns such as the literal of silk screen 610 and figure are printed on the surface that is printed thing 600.

Yet electrostatic printing apparatus always is printed thing being printed under the situation that thing prints continuously a plurality of to each, all must print after 610 times configurations of silk screen are printed thing 600 at every turn again.Therefore, the processing time before printing is elongated, and printing also expends time.So, be in the present situation that to print continuously on the electrostatic printing apparatus substance in the past.

Always, food with container molding under the situation of the strong body of coating parting compound and other edibility powder, as shown in figure 43, use sieve 700 with clathrate mesh, edibility powder 710 is shaken off with the top of container molding 720 from food, and made on its inner surface attached to container molding 720.

Yet, under the situation of using sieve 700, be difficult to make edibility powder 710 attached on the inner side of the container molding 720 and inclined plane, edibility powder 710 generally can drop on the bottom surface of container molding and pile up.And because edibility powder 710 is fallen from sieving 700, so, must select the relatively large powder of particle diameter.But, because big its quality of powder of particle diameter is also big, thus especially be difficult on the side attached to container molding 720, and because own wt drops on the bottom surface of container molding 720 and accumulation.Therefore, there is the problem that edibility powder 710 is coated in equably the inner face difficulty of container molding 720.And even with on the side of edibility powder 710 attached to container molding 720, owing to using sieve 700 to carry out having weakened in the coating process adhesive force of edibility powder 710, a little impact can make it peel off and fall the bottom surface.And under the situation of using sieve 700, because the sieve 700 that rocks from side to side, edibility powder 710 not only can drop in the inside of container molding 720, also can drop externally, so there is the problem that causes a lot of wastes.

And, under the situation of the surface applied edibility powder of molded food product, except that the method for using this sieve, can also be as after in the swing roller 800 of as shown in Figure 44 molded food product 810 and edibility powder 820 being packed into, make swing roller 800 rotations, thereby make on the surface of edibility powder 820 attached to molded food product 810.But, in this case, when making swing roller 800 rotations, can bump between the food 810, exist and cause the shape of food 810 destroyed, there is the problem that causes commodity value to descend.

Carry out under the situation of seasoning at interpolation flavoring in food, usually in the food processing operation, or flavoring sneaked into advance flavor processing in the food, or sprinkle liquid flavoring and add at food surface, or use above-mentioned sieve, the powder shaped flavoring is coated on the food surface.

But, flavoring is being sneaked into food and in food, adding under the situation of flavoring, add hot-working etc. if will sneak into the food of flavoring, then the function of flavoring and local flavor can be destroyed because of heating.And materials such as natural colouring matter are generally thermo-labile, in adding hot procedure metachromatism can take place.

And sprinkling to food surface under the situation that flavoring adds, generally all use liquid quelite, but because the difference of food variety, after coating this liquid quelite, the influence of moisture in the liquid body flavoring, some flavours in food products, mouthfeel can be destroyed.After coating liquid flavouring, food itself can dissolve because of moisture, loses its original function as wheat bran, dried sea sedge etc.

In addition, for example using sieve under the situation of powders such as coating cocoa power on the semi-solid surface such as pudding or jelly, a little less than the adhesive force of powder, the impact in the food conveyance process can make the cocoa power that is coated in food surface come off, or the cocoa power that splits away off solidifies and destroys taste and attractive in appearance.

In addition, also be coated on the edibility thin slice, again this edibility thin slice be placed on the food, the pattern that prints is copied on the food by the edible ink of typographic printing with liquid.When the edibility thin slice being placed on the food surface that contains moisture, the moisture of food surface can make the edibility thin slice dissolve, and copies on the surface of food with the pattern of liquid ink printing.

Yet, because this method is used the edible ink of liquid, therefore, must make the quality thickening of edibility thin slice or make thin slice have resistance to water, when printing, to sustain the moisture of printing ink.Therefore, when trial test uses this edibility thin slice to duplicate the food of pattern, can feel that taste is very poor, and sense of food is also bad.

And, in molded food product, must in mould, pour into a mould in the past, perhaps make different shape by hand, for moulding needs a large amount of labour and time.For example, the preparation method of hawksbill turtle maltosemalt sugar (Turtle first Yee) makes at the granulated sugar that boils dry on the iron plate and falls from nozzle on the pattern model, cools off afterwards and solidifies granulated sugar, and the granulated sugar after will condensing forms from iron plate taking off.For making this molded food product, knack to a certain degree is absolutely necessary.In addition, making under the situation of floriation cake of whipped cream on the steamed sponge cake, be impossible produce beautiful floriation cake if not skilled operators.
