  According to the present invention, the blank baking process can be unmanned, and since the fitting member is fitted in the heat conductive plate in advance, it is possible to reliably attach the blank pattern to the intended position on the product surface. Furthermore, the portion colored by baking was able to have a stable baked color with no uneven baking.

In the production of a white tempered product, the present invention makes it possible to unmanned the tempering process so that the white pattern can be accurately formed at the intended position of the product. For the purpose of enabling application, a heated heat conduction plate fitted with an arbitrarily shaped fitting member is brought into contact with the surface of the product or lightly pressed to A method for producing a white tempered product, which is characterized by performing a white tempered baking.
The present invention also includes a heater, a heat conduction plate having a through hole of an arbitrary shape closely attached to the heater, and the same shape as the through hole of the heat conduction plate, and the heat resistance fitted in the through hole. An apparatus for producing a white tempered ware product, comprising a low thermal conductivity member.

  Tempering is a method of bringing a surface of a product into contact with or pressing a heated heat conduction plate to give the surface of the product the same color as the heat conduction plate and the contact surface or pressing surface. In the invention, the “white blank” means that the color of the product before baking is maintained so that the portion of the area to be colored is not colored by baking. Is to do.

  The “product” in the present invention is not particularly limited. A product having a substantially planar surface is desirable so that the heat conducting plate can be easily brought into contact. In addition, a product having a relatively light color before baking, such as steamed bread, is a suitable product so that a white pattern is conspicuous.

  Any heater can be used as the heater used in the present invention as long as the heat conductive plate can be closely attached and sufficient heating can be obtained. In particular, a heater having a heat source covered with an aluminum outer box is desirable.

  The heater and heat conduction plate need to be closely attached. If there is a gap between the two, the heat conduction from the heater to the heat conduction plate becomes insufficient or non-uniform, and there is a possibility that the baking will not be baked or that uneven baking will occur. Therefore, it is desirable that the surface of the heater in contact with the heat conduction plate be a flat surface that can be easily attached to the heat conduction plate.

  The heat conduction plate of the present invention needs to be formed with a through-hole for fitting the fitting type member, and the shape of the heat conduction plate is preferably a flat plate so that it can be closely attached to the heater without a gap. . The thickness of the heat conduction plate only needs to have a thickness that can form a through-hole into which the fitting-type member can be fitted, and specifically has a thickness of about 5 mm. desirable. If the through hole into which the fitting type member can be fitted can be formed, the thickness may be thinner than 5 mm. On the contrary, the thickness can be increased as long as the heat conduction from the heater is not hindered. However, even if the thickness is increased more than necessary, it is disadvantageous in terms of ease of handling and cost. Moreover, the material of a heat conductive board can be employ | adopted if it is a thing with high heat conductivity, and copper is desirable. In addition, when a plurality of the through holes are formed in one heat conduction plate, it is preferable that a plurality of products can be subjected to whitening baking in a single whitening baking process, which improves productivity.

  The pressing surface of the fitting type member of the present invention can have an arbitrary shape, that is, a desired shape in which a white pattern is desired to be formed. Further, the thickness of the fitting type member is desirably the same as that of the heat conduction plate when the pressing surface of the fitting type member is flush with the pressing surface of the heat conduction plate. In the case where the pressing surface of the fitting type member is protruded from the pressing surface of the heat conduction plate, the thickness is thicker than the thickness of the heat conduction plate, and the pressing surface of the fitting type member is depressed from the pressing surface of the heat conduction plate. Is preferably thinner than the thickness of the heat conducting plate. As the material of the fitting type member, any material having heat resistance and low thermal conductivity can be adopted, and Teflon (registered trademark) is desirable.

  The method for attaching the heater and the heat conducting plate is not particularly limited, and for example, a method such as fastening with a screw or a clamp can be adopted. However, it is necessary to attach them closely so that there is no gap. If there is a gap between the heater and the heat conduction plate, this gap will prevent the heat conduction from the heater, and the surface temperature of the heat conduction plate will decrease entirely or partially, resulting in no color. Or, it becomes a celestial grill with uneven baking. From the standpoint of preventing uneven baking, it is desirable to use screwing for easy attachment of the heater and the heat conduction plate. In order to ensure the close contact between the heater and the heat conducting plate, it is more desirable to screw them to at least four places on the outer periphery of the through hole formed in the heat conducting plate (see FIGS. 6 and 7).

The fitting of the fitting type member into the through hole of the heat conducting plate is, for example, when the hollow pattern is made circular, the through hole is made into a cylindrical shape, and the fitting type member is made into a cylindrical shape like the through hole. If only the fitting is performed, the outer periphery of the fitting-type member may be worn out and may be easily removed. Therefore, an ear portion is provided on the contact surface side of the fitting type member with the heater, and the through hole of the heat conduction plate is formed so as to fit the ear portion of the fitting type member (see FIGS. 3 and 5). ), Which can prevent the fitting type member from falling off, which is desirable. Thus, when the ear portion is provided on the contact surface side with the heater of the low thermal conductivity fitting type member, the ear portion may interfere with heat conduction from the heater to the heat conduction plate. It is more desirable to chamfer and reduce the ear area as much as possible.
When an ear | edge part is provided in a fitting type member, the cross-sectional shape of a fitting type member turns into a reverse convex shape. The cross-sectional shape of the through hole of the heat conducting plate is desirably a shape in which the fitting type member provided with the ear portion is closely fitted (see FIG. 2).

When the blanking tempering is performed with the pressing surface of the fitting type member being flush with the pressing surface of the heat conduction plate, the blanking tempering applied to the product is Since the baked color portion is formed on the same surface, the product surface is desirable without unevenness. In addition, when the blanking tempering is performed so that the pressing surface of the fitting type member protrudes from the pressing surface of the heat conduction plate, However, if the pressing surface of the fitting member is recessed from the pressing surface of the heat conduction plate, the white pattern will protrude from the product surface and the white pattern will become three-dimensional. The product will be visually interesting and desirable.
Moreover, it is desirable to perform a chromium plating process on the pressing surface of the heat conducting plate. By doing so, dirt is prevented from adhering to the pressing surface of the heat conducting plate, and the strength of the pressing surface of the heat conducting plate is increased.

  A prototype of a tempered ware is shown in FIG. A copper heat conduction plate with through holes was attached to the heater controlled in temperature by an external controller with a clamp. A copper heat conduction plate was subjected to a baking test for each of 5 mm, 10 mm, and 15 mm having different thicknesses. The interval between baking is “15 seconds baking → 30 seconds interval” repeatedly, and the result of baking color of 20 steamed breads is the temperature of the surface of the copper heat conduction plate at that time. The changes are shown in Table 1. It was confirmed that a stable baked color could be obtained by adjusting the set temperature of the heater, regardless of whether the copper heat conduction plate of 5 mm or 15 mm was used.

  The white-out tempering device has a structure in which a heat conduction plate is formed in a copper plate having a thickness of 5 mm and a through hole is formed, and a Teflon (registered trademark) fitting type member is fitted, so that the fitting type member does not fall off. The heat conductive plate and the fitting type member were processed to be uneven. That is, as described above, the ear portion is provided on the contact surface side of the fitting-type member with the heater, and the through hole of the heat conduction plate has a shape that fits the ear portion of the fitting-type member. The structure is shown in FIG. 2, and the temperature distribution when heated is shown in FIG. There was a difference of 4 ° C in the surface temperature of the heat conduction plate due to the presence of the lug of the fitting type member on the back surface of the heat conduction plate. there were.

Based on the results of Examples 1 and 2, a white tempering device for an actual production line was produced. FIG. 4 shows a copper heat conduction plate in which the fitting type member is fitted into the through hole. FIG. 5 shows the back surface of the heat conduction plate into which the fitting type member is fitted. The Teflon (registered trademark) insert-type member has a Hokkaido-type chamfering to widen the contact surface of the heat conduction plate with the heater. In Example 2, the problem of uneven baking did not occur even if the fitting member was not chamfered. However, it is considered that the smaller the area of the ear portion of the fitting member, the more advantageous in heat conduction. The production line apparatus is configured to be chamfered. Moreover, the fitting type | mold member was set as the structure that the press surface becomes the same plane as the press surface of a heat conductive board.
FIG. 6 shows a state in which the heat conduction plate into which the above-described fitting type member is fitted is screwed to the heater. The set temperature of the heater was 230 ° C., the surface temperature of the heat conducting plate was measured with a contact-type thermometer, and the results are shown in FIG. The surface temperature when stabilized in the air-baked state is shown in the upper stage, and then the surface temperature after the product was baked 5 times by “15-second baking → 30-second interval” is shown in the lower stage. The maximum decrease in surface temperature after the fifth baking was 5 ° C., the surface temperature was very stable, and the color of the product surface was stable. Furthermore, even if the continuous baking test was performed 20 times, the color of the product surface was good. Moreover, the white pattern part of the celestial baking was formed on the same surface as the part with the baked color, and the product surface was not uneven.

  A baking test similar to that in Example 3 was performed using the same white baking apparatus as in Example 3, except that the pressing surface of the fitting type member protruded from the pressing surface of the heat conduction plate. As a result, the baked color on the surface of the product was good with no unevenness. Further, the white pattern portion was formed to be depressed from the product surface.

  The same baking test as in Example 3 was performed using the same white baking apparatus as in Example 3, except that the pressing surface of the fitting type member was recessed from the pressing surface of the heat conduction plate. As a result, the baked color on the surface of the product was good with no unevenness. Moreover, the white pattern part protruded from the product surface.

  At least two people are required for the baking process of the white baked products, and if the mold holder is not placed carefully at the intended position, the white pattern will be the intended position of the product. There is a risk that the commercial value of the white tempered product will be reduced. According to the present invention, the blank baking process can be made unattended, and the white pattern can be surely attached to the intended position on the product surface. As a result, a method and a manufacturing apparatus for a white tempered product that can produce a stable baked color without any color may be developed, which may increase the commercial value of the white tempered product.
