Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for recycling moist ice cream cone cups or wafers.

Conventionally, ice cream cone cups or ice cream wafers tend to get damp during storage, and once they get damp, they become deformed depending on the simple drying method, so the product loses its value and cannot be sold commercially. It was impossible to do so, and the only option was to dispose of it, which was uneconomical.

In the present invention, ice cream cone cups or wafers, which are recycled raw materials, are heated under reduced pressure using oil, thereby making it possible to dehydrate them in a short time, preventing thermal deterioration and carbonization of the recycled raw materials, and creating a new final product. Ice cream cone cups or wafers can be reused as wafers, and by coagulating and stabilizing the gluten in the recycled raw materials, recycled ice cream cone cups or wafers can be stored for long periods of time by making the recycled cone cups less susceptible to moisture. The purpose is to provide a recycling method.

The detailed description of the embodiments of the present invention is as follows. That is, a single or mixed oil such as animal oil, vegetable oil, fish oil, etc. is stored in a 4.5 m ³ airtight container, and the oil is heated by steam that is pressurized into the jacket of the container, so that the oil temperature is approximately 60℃～120
Heat it around ℃.

Next, 5,000 kg of wet ice cream cones or wafers, which are recycled raw materials, are put in and soaked, and the cupper is closed.

Next, the temperature of the heating oil is maintained at about 60°C to 120°C while stirring inside the cupper, and the pressure inside the cupper is reduced.

This depressurization treatment is carried out under small reduced pressure conditions, that is, 10 to 20 mmHg, for the first 30 minutes or so after immersing the recycled raw material, and the oil is heated to promote evaporation of water in the recycled raw material to achieve dehydration. 750mm
The pressure of Hg is reduced and the water is dehydrated to a water content of about 3 to 6% in about 60 minutes in a substantially vacuum state.

By heating under reduced pressure in such oil, the heated oil uniformly penetrates into the tissue of the regenerated raw material, and this is configured so that it replaces the water in the tissue, allowing the absorbed water to evaporate rapidly. The structure is such that the gluten in the raw materials is coagulated and stabilized.

Next, the recycled raw material that has undergone the dehydration process is taken out of the Kutsuka, and is physically squeezed using a Kusuriyu press or the like as a squeezing device, or centrifuged using a centrifuge to separate and remove the oil. After that, the oil is removed using a deoiling agent such as normal hexane, and the product is pulverized into a fine powder.

This finely divided product can be mixed with cornstarch, wheat flour,
Powdered milk, egg yolk, etc. are added to raw materials for ice cream cone cups or wafers and kneaded to regenerate new ice cream cone cups or wafers.

According to the present invention, since moist ice cream cone cups or wafers are heated under reduced pressure through oil, the heated oil uniformly penetrates into the tissue of the recycled raw material, and this replaces the moisture in the tissue. , the moisture evaporates rapidly, making it possible to process the threshing machine water in a short time, preventing thermal deterioration and carbonization of recycled raw materials, and making it possible to recycle the final treated product as new ice cream cone cups or wafers, and Gluten in the recycled raw material is coagulated and stabilized by heat treatment under reduced pressure through oil, and when the final processed product is used as new ice cream corn cups or wafers, the new corn cups etc. are less likely to get damp. It has the effect of being suitable for long-term storage.

Claims (1)

[Claims] 1 In a sealed container, moist ice cream cones or wafers, which are recycled raw materials, are placed in indirectly heated animal and vegetable oil and immersed, and the temperature of the animal oil and vegetable oil is adjusted while reducing the pressure inside the sealed container. The heated animal oil or vegetable oil is stirred and heated as a heat medium, and in the initial depressurization process, heating is performed under a small reduced pressure condition, followed by a large depressurization, thereby dehydrating the water in the recycled raw material and The gluten in the recycled raw material is coagulated and stabilized, then the dehydrated recycled raw material is taken out from the closed container, the oil is separated by compression or centrifugation, the oil is removed with a deoiling agent, and it is pulverized and made into ice cream. A method for recycling moist ice cream cone cups or wafers, which comprises reusing them as cream cone cups or wafers.
