Description

This device is an egg thermometer used when heat-treating eggs with shells such as boiled eggs.
More specifically, the present invention relates to an egg thermometer used to easily and easily obtain a processed egg obtained by heat-treating a raw egg such as a boiled egg or a hot spring egg at home.

  Usually, in order to obtain shell-cooked eggs such as soft-boiled eggs and hot spring eggs (hereinafter also referred to as “heat-treated eggs”) at home, water is poured into cooking utensils such as pots. Is heated to an appropriate temperature, and then a raw egg is placed in hot water and heated for a predetermined time under an appropriate temperature control.

For example, hot spring eggs are usually obtained by heating water to about 50-70 ° C., then pouring raw eggs into the obtained hot water, and heating for about 30 minutes under temperature control at this temperature. It is done.
In addition, the coagulation temperature of egg yolk is about 70-80 degreeC.

A hot spring egg is one in which the egg white is not completely solidified, the whole is in a trotting state, and the egg yolk is cooked in a sticky bowl-like state.
An example of an apparatus and a method for manufacturing such hot spring eggs is disclosed in, for example, Utility Model Registration No. 30805599 (Patent Document 1) and Patent No. 4526519 (Patent Document 2).

  On the other hand, Patent Document 1 proposes a cooking device for easily creating hot spring eggs that have the same yellowish firmness and whiteness softness as genuine hot spring eggs without special techniques at home. Yes.

  This cooker has a plurality of eggs in which the temperature of eggs to be used before cooking is constant, a means for allowing the eggs to be accommodated in and taken out from the container, and the temperature of water in the container in which the eggs to be cooked are kept constant. And means for notifying that the water in the container has reached a certain temperature and means for notifying that the egg has reached a certain time in the container.

  On the other hand, Patent Document 2 proposes a method for producing boiled eggs, which allows industrial production of boiled eggs to be performed more inexpensively and efficiently.

This boiled egg manufacturing method uses superheated steam as a processing steam when heat-treating an egg, and is performed in a closed processing chamber in which no pressure is applied.
The processing chamber is formed by stacking a plurality of processing areas in the height direction to heat the eggs while transferring the eggs substantially horizontally, and a flat nozzle that ejects superheated steam at the boundary of each processing area Is provided so as to partition each processing area, so that the ambient temperature can be gradually increased from the lower processing area to the upper processing area.
Therefore, the eggs are sequentially sent from the lower processing area to the upper processing area, and the heat treatment proceeds.

Utility Model Registration No. 3080599 (Scope of Claim for Utility Model Registration, Fig. 1) Japanese Patent No. 4526519 (Claims, FIG. 1)

  When trying to obtain hot spring eggs with a softer egg white than egg yolk in ordinary households, it is surprisingly difficult to finely adjust the heating condition of the hot water used to treat the eggs, and excessive heating causes the eggs to coagulate more than necessary. Therefore, it has been extremely difficult to obtain a desired finished product.

  Furthermore, since the cooking device described in Patent Document 1 is a dedicated one for producing hot spring eggs, there is a problem of lack of versatility as a cooking device.

  Furthermore, the invention described in Patent Document 2 has a problem in that it can industrially produce a large number of hot spring eggs and cannot be used for general household use.

  The egg thermometer according to the present invention has a temperature suitable for manufacturing a desired heat-treated egg (for example, a temperature of 50 to 70 ° C., particularly a temperature around 50 ° C. and / or a temperature of 65 to 70) on the outer peripheral surface of the thermometer. Since a reversible temperature indicating material that changes color is attached at the boundary of around 0 ° C.), when producing a heat-treated egg, the egg thermometer is put into the cooking utensil together with the egg. Whether the temperature of the hot water in the appliance is suitable for obtaining a heat-treated egg can be determined at a glance by looking at the color of the reversible temperature indicating material applied to the outer peripheral surface of the egg thermometer. Therefore, a heat-treated egg can be easily obtained.

  In particular, when a reversible temperature indicating material that changes color at a temperature of 50 ° C. and a reversible temperature indicating material that changes color at a temperature of 65 to 70 ° C. are attached to the outer peripheral surface of the thermometer main body, It is possible to prevent the eggs from coagulating more than necessary by heating at a temperature higher than the temperature suitable for the production of hot springs, so that it is possible to easily and reliably obtain hot spring eggs in a desired finished state. .

The egg thermometer according to the present invention is used by being attached to various conventional cooking utensils such as a pan with a handle, and is therefore highly versatile and very convenient.
