Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing pseudo-rice cakes, and more particularly, to a method for producing pseudo-rice cakes that can be used semi-permanently and are primarily used as decorations, such as kagami-mochi.

As the price of mochi has soared in recent years, cheap imitation mochi made of synthetic resin has become widely available as New Year's kagami mochi, but these are manufactured using the same method as regular synthetic resin products and cannot be distinguished from synthetic resin products at first glance. , it was too chewy to be used as a New Year's rice cake.

On the other hand, it is also possible to make pseudo-mochi using paraffin, such as in cooking samples at restaurants, etc. In this case, although it can be made to look just like the real thing, it is sensitive to heat and is bulky, can only be used for about a year, and is expensive to manufacture. It was expensive.

This invention was made to solve these problems, and was made to provide a pseudo-mochi at a low price that looks exactly like the real thing in terms of shape, color, luster, texture, etc. and can be used semi-permanently. be.

Moreover, it also takes into account the sticky rice powder adhering to the surface of the mochi, which is not considered in conventional pseudo-mochi.

That is, the method for producing a pseudo-mochi according to the present invention involves injection molding a soft thermoplastic resin into a mochi shape at a temperature lower than its melting point to form an opaque pseudo-mochi, and then soaking the pseudo-mochi in an organic solvent to form a pseudo-mochi. In this method, the surface of the mochi is melted and then taken out, and powder is sprinkled on the pseudo-mochi surface before it hardens. Next, a method for producing a pseudo-rice cake according to the present invention will be explained based on the drawings.

The drawing is a process flowchart, and in injection molding process A, when a soft thermoplastic resin v made by kneading vinyl chloride resin etc. and a plasticizer is injection molded into a rice cake shape at a temperature lower than its melting point, the surface becomes glossy. A certain milky white opaque elastic pseudo mochi la is formed.

Needless to say, if injection molding is carried out at the melting point temperature as in normal injection molding, the result will be a transparent pseudo-rice cake, and even if a coloring agent is used in combination, the color of the rice cake will not be achieved.

In addition, in the case of red rice cakes, etc., if a coloring agent is used in combination and injection molding is performed at a temperature lower than the melting point, similar colors similar to those of the real thing can be obtained.

In the next soaking step B, the pseudo-mochi 2a is immersed in an organic solvent such as thinner, the surface of the pseudo-mochi 2a is melted, and the surface of the pseudo-mochi 2a is created with invisible unevenness, and then taken out to form a dull pseudo-mochi lb. It is used as a preliminary treatment for the next step.

In the next surface finishing step C, the melted surface of the simulated rice cake Ib is sprinkled with powder such as rice flour and adhered to it while it is still sticky before hardening, thereby completing the simulated rice cake I.

That is, even in normal mochi production, when freshly made mochi is shaped into a round or plate shape, the surface of the mochi is sprinkled with rice flour called mochitori powder to prevent the mochi from sticking to other objects.

As described above, the soft thermoplastic resin is injection molded into the shape of a rice cake at a temperature lower than its melting point using an injection process that is almost the same as the conventional method, resulting in an opaque color and a soft texture similar to that of a rice cake.

In addition, by adding a simple process that does not require special equipment,
This is a useful invention that melts the surface of the simulated rice cake to remove its luster and gives it a real-like texture by adhering powder, and provides a low-cost pseudo-rice cake that looks like the real thing and can be used semi-permanently. Next, embodiments of this invention will be described.

Example (2) 50 parts of a powdered vinyl chloride resin with a melting point of 200°C and 5 parts of a plasticizer were mixed and kneaded in a hot tumbler at a set temperature of 10,000 for 6 hours.

(2) Form the kneaded product into a string using an extruder and crush it into a pellet to homogenize the soft vinyl chloride resin raw material.

■Next, injection molding is performed using the above pellet-shaped soft vinyl chloride resin as a raw material. For the first minute, the injection molding part is preheated by blank firing at the set temperature of 200°C, which is the melting point, and then the set temperature is The temperature is lowered to 170°C and injection molded into a mochi shape.

■ Place the molded pseudo-mochi in PVC thinner for 3 minutes.
Soak for 5 minutes to dissolve the surface of the simulated mochi, take it out and put it in the atmosphere for 5 minutes.
Leave for a second.

■ Then, sprinkle rice flour evenly on the surface of the pseudo-mochi by hand to complete the pseudo-mochi.
