Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shallow plate-shaped or cup-shaped edible container for storing cold confectionery such as soft ice cream and ice cream, and various foods, that is, it has a small apparent specific gravity, is porous, and has a light taste. The present invention relates to a method of manufacturing an edible container that is pleased to be crispy.

[0002]

2. Description of the Related Art In general, edible containers and plate-shaped edible substrates that sell cold confectionery such as soft ice cream and ice cream at stores are sold by each manufacturer by adding a large amount of water to raw materials such as flour. The so-called water type kneaded by kneading is heated and baked with a high-temperature heating plate, or a waffle cone or a waffle cup with a cup shape formed by heating and baking this plate-shaped body into a cone or tart. The dish-shaped edible containers that hold sweets are packed and delivered to the ice cream and tart confectionery sales sites.

Waffles, wafers, waffle cups, and edible plates for tart confectionery are fragile because their mouths are crispy, and they are hard to withstand a little impact, and are easily damaged during storage or transportation. Of course, there are many handling difficulties not only at the time of factory shipment but also at the ice cream and confectionery sales sites after shipment.

In order to eliminate these problems, there is a method of manufacturing an edible container described in Japanese Patent Application Laid-Open No. 4-148638 which was previously developed by the present applicant. This method comprises a step of flowing down and spreading a water species 2 which is a mixture of raw materials such as wheat flour, sugar, fats and oils and water onto a heating plate 10 and a kneaded product 2A on the heating plate 10 which is flowed down and spread in this step. When sandwiched by another heating plate, the wheat starch in the kneaded material 2A is converted into an alpha, and the kneaded material 2A
A heating and drying step of heating and drying to such an extent that the water content in A evaporates, and the plate-shaped forming body 5 heated and dried in this step is peeled from the heating plate 10 in a dry state and conveyed to the next humidifying step. A conveying step, a humidifying step for newly humidifying the plate-shaped forming body 5 conveyed in this step, and a finish heating step for newly heating and drying and softening the humidified plate-shaped article 6 moistened in this step, The method for producing an edible container is characterized by further comprising a forming step of forming the heat-dried and softened plate-shaped body 9 that has undergone this step into a desired shape.

[0005]

However, since the humidified plate-shaped product in this conventional method has a sticky surface, it cannot be polymerized until it is spread and dried one by one. It takes about 6 hours and a long time, and the water content changes greatly due to changes in the drying atmosphere, causing mold growth or conversely drying too much and causing cracks.

In order to eliminate the above-mentioned problems, the present invention prevents moisture from evaporating during the distribution process by shipping the hydrated plate-shaped product in a moisture-proof sealed state before shipping. The hygienic edible container is shipped as described above by measuring the infiltration of water into the product to prevent contamination of various bacteria and cracking defects, and then heat-drying and softening it again at the shipping destination to mold and solidify it into a dish or cup. The purpose is to obtain low energy first.

[0007]

Means for Solving the Problems The above-mentioned object of the present invention is to provide a step of flowing down and spreading a water species obtained by kneading raw materials such as wheat flour, sugar, fats and oils and water onto a heating plate, and the heating through the steps. The water species on the plate is sandwiched between other heating plates, and the wheat starch in the water species is gelatinized, and a heat drying step of heating and drying to such an extent that the water in the water species evaporates, and heat drying in this step A watering step of re-hydrating the plate-shaped body after the plate-shaped body is peeled off from the heating plate in a dry state, and a sealing step of sealingly storing the water-containing plate-shaped product that has undergone this step in a moisture-proof packaging bag. And, after taking out the softened plate-shaped product made of the hydrated plate-shaped product that has been softened by the permeation of the water content in the moisture-proof bag from the moisture-proof bag, heat-dry the softened plate-shaped product again. Finish heating step to soften and soften, By after molding cooling and solidifying the heat drying softening already shaped body through the steps to shape such as plates and cups,
This can be achieved by including a molding step of molding into an edible container.

[0008]

By heating the water species with a heating plate at about 170 ° C to 220 ° C, it is possible to prepare a plate-shaped formed body with a water content of about 3% that has been dried by heating.

Since this plate-shaped formed body has a low water content, it can be easily peeled off from the heating plate with a scraper or the like.

Since the peeled plate-like formed product becomes hard and brittle when it is cooled as it is, and easily cracks with parin, in this invention, for example, about 20 g of the plate-shaped formed product after peeling with a water spray is about 2 g. After spraying a certain amount of water and finally making it moist so that the water content is about 10 to 15%, this hydrated plate-shaped product is sealed and stored in a moisture-proof packaging bag for storage or transportation. be able to.

With the passage of time, the above-mentioned hydrated plate-like product becomes a soft plate-like product that is soft and bendable evenly moistened by the infiltration of hydrated water in the moisture-proof bag, so that it is suitable for storage and for users. It is easy to handle when it is transported, and it is not damaged or cracked, and it is hygienic because it does not spoil or mold due to contamination by various bacteria.

On the user's side, the softened plate-shaped product that has been transported is newly heated and dried in order to form it into a plate or cup, and finish heating for softening is performed.

At this time, since the water contained in the softened plate-like product adheres to the surface of the tissue in a state of almost humidity, dehydration and drying thereof do not require heat change of the tissue of the plate-like product. ,
This plate-shaped product originally has a water content of 10 to 1 as structural water.
The time required for the above-mentioned finish heating and drying can be remarkably reduced as compared with the other plate-shaped body prepared to 5%, and the heater power amount per sheet can be reduced to about one third.

Then, the heat-dried and softened plate immediately after being softened by the softening and fluidizing action of the sugar and fats and oils contained in the finish heat-drying is formed into a plate-like or cup-like shape and then cooled and solidified to obtain a hygienic edible product. Containers can be made and sold.

[0015]

Then, a calciner main body 22 including a heat ray reflective sheet 19 and a heat plate 21 having a heater 20 sandwiched in the center is provided on a heat insulating and heat insulating material 18 laid flat on the upper plate 11a of the lower case 11.

Further, a heat ray reflecting sheet 27 and a heater 28 are provided at the center on the lower surface of a heat insulating heat insulating material 26 attached so as to close a lower opening 25 of an upper case 24 connected to a rear upper edge of the main body of the calciner by a hinge 23. By providing each of the calciner lids 30 having the hot plates 29 that are sandwiched and attached, a suitable finish calciner A can be configured for use in the finishing heating step in the present invention.

This baking device A is installed at the store of an ice cream or soft ice cream shop, and the preset heaters 20 and 28 are set and controlled in the range of 110 to 150 W by the knob 15a to heat the hot plate 2.
The temperature of 1,29 is controlled, and the desired firing elapsed time is set to be announced by the knob 15b.

The heaters 20 and 28 have a constant temperature, for example 170 to 2
When the temperature rises to about 30 ° C., the baking device lid 30 is opened via the hinge 23 as shown in FIG.
When 6A is placed on the hot plate 21 and the baking lid 30 is closed around the hinge 23 with the handle 30a, as shown in FIG. 8, the above product 8 is between the hot plates 21 and 29 by the hot plates 21 and 29. Finish firing.

This firing time is set by the time setting knob 15b so that the heat-dried and softened plate-like body 9 which has been baked up in a constant state can be produced immediately with the operation of the firing temperature controller 16. 9 through the state shown in FIG.
A cup-shaped edible container C can be obtained by molding as shown in FIG.

That is, the molding process will be described in detail. As shown in FIG. 9, the heat-dried and softened plate-shaped body 9 is placed on the upper surface of the female mold 32 having the cup-shaped recess 31.

In the initial heating and firing, if the heating plate 10 is engraved with the grid-shaped irregular stripes 4, the plate-shaped forming body 5 and the hydrated plate-shaped product 6 also have a grid stripe pattern. It is possible to obtain an attached edible container.

Since this edible container C is slightly cooled at the same time as molding and is in a cured state after molding, the edible container C does not lose its shape. Can be purchased by purchaser C
Since it is possible to hold the edible container, the edible container C does not become dirty even after eating the ice cream in the edible container,
The edible container itself can be eaten hygienically afterwards.

Since the hydrolyzed plate-shaped product 6 and its softened plate-shaped product 6A are preheated and processed, the wheat starch is pregelatinized and the protein in the wheat flour is also hardened to some extent. Since the water content is about 10 to 15%, it can be delivered with almost no fear of breakage during transportation because it can withstand impacts and does not break or crack.

Further, at the time of initial heating, the plate-shaped body 5 which has been heated and dried is heated by the heating plate 10 in order to sufficiently evaporate water and dehydrate it.
Is very easy to peel off, and since the hydrated plate-shaped product 6 and its softened plate-shaped product 6A are only moistened by the amount of 10 to 15% by weight, they are dehydrated in the finishing heating process such as at ice cream retailers. A small amount of heat is required for the heating, and not only the firing time in the field can be significantly shortened but also the problem of heat dissipation is solved.

Next, the above embodiment will be described more specifically.

Wheat flour 100 Sand sugar 40 Fats and oils (coconut oil) 10 Salt 0.2 (Slightly containing chicken eggs, milk, salt, coloring agents, fragrances, etc.) Water 100 is thoroughly stirred and mixed to prepare water species 2.

Then, as shown in FIG. 2, this water species 2 is spread down on a heating plate 10 engraved with grid-like uneven stripes 4 at intervals of 10 mm in length and width, and the surface of the heating plate 10 is 1 in advance.
It is heated to about 80 ° C to 200 ° C and then spread down and another heating plate 10b is placed below the other heating plate via a hinge 10c.
The water species 2 pressed against the upper surface of 10a is sandwiched between both heating plates 10a and 10b, and the temperature of the water species 2 is maintained at 170 ° C to 200 ° C for a certain period of time, for example 60 seconds, to heat the water species 2 to a brownish color and to remain. After baking so that the water content is 4% or less, heating plate
Open both 10a and 10b and scrape the plate-shaped body 5 with the scraper SC.
And take it out. (A) The conditions for the spreading and heating of water type 2 are as follows: (1) The amount of water flowing down once is approximately 25 cc (2) The temperature of the heating plates (one set of upper and lower) 180-200 ° C (3) Mutual heating plates The space between the two is determined by the thickness of the water species 2 that has spread down, and this is about the thickness of the fired product. (B) Conditions of heat processing (1) Heating plate interval This is the thickness of the firing base (disc-shaped firing product).

(2) Firing temperature time 180 ° C. (firing plate surface)
200 ° C, time 45-90 seconds (3) Situation of fired substrate (disc-shaped fired product) (4) Residual water content of heated fired substrate (using moisture meter of Ket company) (5) All heating plate intervals are 2.5m / Let m.

Time is 180 ° C. for 90 seconds 200 ° C. for 60 seconds (7) Condition of heat-dried plate-shaped body 5 and residual moisture (111) (170 ° C., 90 seconds) Slightly yellowish brown, slightly hard Residual water 4.0% (121) (200 ° C, 60 seconds) Brown, hard residual water 2.3% Both have a height of about 1.5 mm on both surfaces 10 A heat-dried plate-shaped formed body 5 having a grid of millimeter grids is obtained.

This plate-shaped product 5 can be eaten as it is because the wheat starch is gelatinized, but in the present invention, the plate-shaped product 5 which has been dried by heating is peeled off from the heating plate 10 in the dry state and As shown in 1, the plate-shaped forming body 5 is conveyed to the next watering step again and the water content is 10 to 10 at the watering step.
After water-spraying to about 15% and adding water to make a hydrated plate-shaped product 6, it is sealed and stored in the moisture-proof bag 8 in the water-containing state and carried into the user side.

With the passage of time, the water content of the hydrated plate-shaped product 6 that has been hermetically sealed is gradually infiltrated into the product 6, and the entire product 6 becomes a water-containing state with a water content of about 10 to 15%. A flexible plate-like product 6A that is flexible and reduces stickiness on the surface and does not cause damage or cracks even when bent by external force
Becomes

Then, the user takes out the softened plate-shaped product 6A from the moisture-proof packaging bag 8 and then heats it again in the finishing heating process, and finish-heating it to heat-dry the softened plate-shaped product by the softening and fluidizing action of sugar and fats and oils contained therein. Immediately after the production of 9, the edible container C (Fig. 10) having a crispy texture with a pleasant mouthfeel was obtained by molding it into a cup shape, a dish shape or the like and then cooling and solidifying.

The same is true for the disk-shaped finish-heat-dried and softened plate-shaped body 9 that has been cooled without being molded.

In each case, the mouthfeel was crispy, and although the taste was delicious, the difference in the heating conditions was felt to some extent as the texture.

Further, the above-mentioned softened plate-shaped product 6A requires a finishing heating time of about 20 seconds at 180 ° C. when the water content is 10%, and a finishing heating time of 35 seconds when the water content is 15%. In short, after all, it is clearly seen that the watering conditions affect the finishing heating.

The edible container C may be in the shape of a cone, a plate, a bowl, or any other shape other than the cup.

[0046]

Since the present invention is constructed as described above,
The following effects are achieved. By heating the kneaded material 2A with the water species 2 by the heating plate 10 at about 170 to 220 ° C., it is possible to prepare the plate-shaped formed body 5 which has been dried by heating, and the plate-shaped formed body 5 has a water content of 3%. Heating plate 10 because it is small and small
The first effect is that it can be easily peeled off from above with a scraper SC or the like, and can be easily conveyed to the next step.

The peeled plate-like formed body 5 becomes hard and fragile and easily broken when cooled as it is. Therefore, particularly in the present invention, about 20 g of the plate-shaped formed body after peeling is formed.
About 5 grams of water is sprayed on 5 with water spray to add water to a water content of about 10-15%.
It can be stored in a moisture-proof bag 8 in a sealed manner and can be made into a flexible plate-shaped product 6A due to water seepage over time, and since this plate-shaped product 6A is flexible and bendable, it can be stored, transported, etc. It has a second effect that it is easy to handle and has good handling property and is not chipped or cracked.

Further, in the present invention, since the hydrated plate-shaped product 6 can be immediately sealed and stored in the moisture-proof bag 8 as it is, there is no need for a waiting time for drying, so that it is hygienic without contamination by bacteria and can be shipped in a flowable manner. It has a third effect.

The above-mentioned softened plate-shaped product 6A is a moisture-proof bag.
The fourth effect is that it is hygienic because it can be sealed and stored in 8 and shipped to users such as ice cream vendors to prevent miscellaneous bacteria and mold from forming in the distribution and storage processes that reach users. There is also.

When the softened plate-shaped product 6A is newly heated and dried and finish heating for softening is performed, the water contained in the plate-shaped product 6A adheres to the surface of the tissue in a state of almost humidity. Since the dehydration drying does not require thermal change of the structure of the softened plate-shaped product 6A, the above-mentioned finish heating drying is compared with the plate-shaped formed body having the original water content of 10 to 15%. The time required for the above can be significantly reduced, and the electric power consumption of the heater per sheet can be reduced to about one-third. Therefore, the running cost can be reduced, and there is a fifth effect such as being economical.

Then, the heat-dried and softened plate-like body 9 immediately after being softened by the above-mentioned finishing heat-drying is quickly formed into a cup shape or a dish shape by the softening flow action of the sugar or fat contained therein, and then cooled and solidified, so that a sanitary condition is obtained. Since the edible container can be made and sold quickly, there is a sixth effect that the waiting time of customers can be shortened as much as possible.
