Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention utilizes a synthetic resin sheet material, softens it by heating, and molds it into a desired shape by a molding method such as a vacuum forming method or a blow molding method. This is a container for tofu, in which a tofu producer fills it with uncoagulated tofu stock solution, seals it, uses the container itself as a mold for coagulation, and solidifies it inside the container.
This is a packaging container for tofu that can be transferred directly to the distribution channel.

<Prior Art> Conventionally, this type of tofu container made of a synthetic resin sheet was a container made by directly molding an ordinary synthetic resin sheet.

Problems to be Solved by the Invention In a container made of such a synthetic resin sheet as it is, the container itself is used as a mold for coagulation by the method described above, and the tofu stock solution is coagulated within the container. When used as a container for a manufacturing method in which the tofu is cooked, the coagulated tofu will adhere to the container, and when the consumer turns the container upside down to take out the tofu, the tofu will stick to the container, especially at the connection between the bottom and the 8th wall of the container, especially at the corner corners. To avoid the drawback that the tofu parts stick to each other and come apart, and the top edge part of the tofu taken out, especially the corner part, loses its shape, making it impossible to take out the tofu in a beautiful shape that retains the shape of the container. It wasn't a fake.

<Means for Solving the Problems> Therefore, the inventor of the present invention initially conducted various studies on molding molds in order to finish the inner surface of the container smoothly.

By giving the protruding mold a mirror finish to make the inner surface of the container as smooth as possible, by heating the protruding mold to various temperatures, and by adjusting the pressure molding time, the structure of the inner surface of the container can be improved. Although various research efforts have been made over many years, such as trying to make the material more precise, no good results could be obtained.

Therefore, the inventor of the present invention found that when using a container made of this kind of synthetic N# fat sheet and using the tofu manufacturing method as described in Section 111, it is inevitable that the tofu would lose its shape when taken out, and there is no solution to the problem. However, because I was in a position where I had to solve the problem, I fundamentally changed my technical thinking and came up with the idea of applying a release agent to the inner surface of the container. It's arrived. but,
As a result of experiments, this method did not lead to satisfactory results. As a result of further research, we developed a system that absorbs moisture from solidified tofu, interposes the absorbed water between the top of the container and the tofu, and uses this water to float the tofu inside the container. It's arrived.

The structure is a container made of a synthetic resin sheet whose inner surface is coated with a moisture-absorbing and dehydrating agent for food.

<Function> Coating the inner surface of the container with a moisture-absorbing and dehydrating agent (!:
By using the surface activity of the moisture-absorbing and dehydrating agent, the water in the tofu in the container is dehydrated, forming a water film between the container and the tofu, and separating the tofu from the container. It is used as a.

<Example> Next, examples of the present invention will be described.

First, an example of the method for manufacturing a container according to the present invention will be described.

As shown in Figure 1, a coating agent solvent (suspension agent) is constantly stirred by a stirrer on one side (lower side in the figure) of 1 synthetic SL fat sheet material (fl).
A booth (2) where the coating agent is sprayed from a tank (T) via a pump (P) with a spray nozzle (SN).
), then transfer this coating agent sprayed sheet to the next process, heat and soften the sheet (2) which also serves as drying of the coating agent in a heating booth (3), and then place it in a molding booth +41vc for the next process. The beans are molded, cut into single containers in the next cutting booth (5), and packaged in the packaging booth (6) before being transported to a bean FK manufacturer.

In the above manufacturing process, the coating agent spray booth (2) is placed in front of the molding booth (4). However, if this spray booth (2) is accompanied by a drying process, the molding booth (4) It will be easily understood that a method may be adopted in which the molded container is coated by arranging the container at the next position (in two locations) and coating the container after the molding. Alternatively, an application method using a roll or, in some cases, an artificial application method using a feather or the like may be used.

The shape of the container according to the present invention is as shown in FIG. It is a dish-shaped container placed upright inside the body, and the layer 'I m
A type in which horizontal tank portions 04) are arranged in series from the upper edge of +131 toward the outside is mainly used.

The food-grade moisture-absorbing and dehydrating agents used in the experiments as coating agents were soya lecithin extracted from soybeans, which is a raw material for tofu production, and sulfate lucicum, which is used as an indispensable coagulant in tofu production. Calcium 5ulfate) is used in various foods such as ice cream, mayonnaise, and putter, and beans Fpl! ! ! A monoglycerin fatty acid ester, which is a monotype of the hydroxyl group of glyceride, which is also used as an antifoaming agent in manufacturing, and a mixture of the calcium sulfate and monoglycerin fatty acid ester in a ratio of 2 to 1. (hereinafter referred to as a mixture).

Fruit-h is the above-mentioned soyalentin, sulfur chloride 7cum.

Monoglycerin monofatty acid ester and mixture were used in that order, and in the case of rift two, the results were far from perfect, but compared to conventional products, the results are considered to be extremely good. be able to. In the case of glycerides, supplementary confirmation tests were performed on di- and tri-types, which differ due to their hydroxyl groups, and very satisfactory results were obtained, similar to the mono-types. Very satisfactory results were likewise obtained with the mixture.

The coating film thickness of the coating agent may vary depending on the manufacturing process of each material.
3 of those of about 10p, those of about jμ, and those of about 10p
Seeds were created and used as experimental materials. Supplement a: I created films of various thicknesses for the imperial edict and submitted them to supplementary materials.
When the film thickness is about 0.7μ, the effect becomes obvious.
If the thickness exceeds about 700μ, peeling phenomenon may occur when transporting it in an unused state or when setting it on a 001 machine.

It was also confirmed that there is no need to make it that thick.

It was also confirmed that monoglycerin fatty acid ester has good adhesion to containers and acts like an adhesive.

For each material, experiments were attempted using at least jOθ individuals, but the experimental data below is converted into data for each type of 7,000 individuals and displayed.

As is clear from the above table, monoglycerol fatty acid ester or mixture is used as a coating agent [11
In some cases, the patient was healed and a satisfactory result was obtained.

The inventor of the present invention discovered that tofu has a very variable taste.

Since this is a food product that requires delicate adjustment techniques such as coagulation hardness, the coating agent was selected from among the substances used in the tofu manufacturing process. It is not limited to only the variety. For example, carboxylic ac
id) and mixtures thereof can also be used as coating agents.

<Effects of the Invention> As explained above, the present invention is used in a manufacturing method in which a container is directly filled with a tofu stock solution, and the container itself is used as a frame for coagulating Q-curd, and the filled stock solution is coagulated within the container. The container is a container formed by using a synthetic resin sorting material, for example, by a blow molding method, and the inner surface of the container is coated with a moisture absorbing and dehydrating agent for food. There is no particular cost increase in the manufacturing process compared to conventional products, and there is no corner cut when taking out tofu, which was thought to be an issue that could not be solved with conventional containers of this type. There are four remarkable achievements that have led to a near solution.
