Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boiler / stirrer for efficiently producing high-quality custard cream free from so-called lumps and scorching.

[0002]

2. Description of the Related Art Conventionally, there is no special cooking and stirring machine only for custard cream, and therefore, the manufacturer uses egg yolk or soft flour, constellate, milk, sugar, butter, etc., which are the raw materials of custard cream, as a predetermined mixing ratio. It is placed in a pan set in a steam pot, boiled and cooked with the heating steam from the boiler, and then stirred by a common mixer.

Further, in that case, since the above-mentioned egg yolk, soft flour and corn starch are easily burnt, it is customary to first boil milk and sugar until they boil and then mix and stir the above-mentioned burnt raw materials. However, it is widely used because it is less likely to burn compared to an open flame of gas.

[0004]

However, in order to prevent the above-mentioned raw materials from burning, the steam pot itself is made of heat-insulating material such as asbestos even if it is boiled with heated steam, and the custard cream In that case, due to the egg yolk and soft flour of the raw material, it is necessary to stir for a long time because the so-called lump easily occurs, so the above-mentioned scorching raw material will inevitably stick to the bottom of the pan. is there.

Further, in the steam type, when the boiler starts operating, the pressure rises, and when it reaches a certain maximum pressure, not only the operation stops, but also the pressure reducing action of the pressure reducing valve used together enters into this. Since it is non-uniform due to the difference in the coming pressure, the heat calories given to the pan and the time required for finishing the custard cream are not constant, which adversely affects the chemical change of the sugar in the above raw materials.

The sugar begins to decompose at about 80 ° C.
When it reaches 50 ° C, it undergoes a rapid chemical change, that is, a coloring reaction to brown and a change to reducing sugar. Then, the coloring reaction and reducing sugar bring out the deliciousness of sugar, but it is impossible to raise the heating temperature to about 150 ° C. in the above-mentioned steam method, so high-quality delicious custard cream. Can not be obtained, and the sweetness of sugar itself will inevitably remain on the tongue.

Further, in the case of custard cream, even if the raw material egg yolk is well stirred and the soft flour is strained well, if it is caking and solidifying with cooking, so-called lumps are likely to be formed, and the taste is deteriorated, and the appearance is deteriorated. The top is also difficult to finish into a uniform cream.

Therefore, it is necessary to stir for a long time, but even if the stirring action is continued for a long time, the conventional mixer is provided with a rotary shaft and a plurality of blade plates protruding from this. As the inside of the pot simply rotates, the egg yolk and the soft flour are difficult to mix with milk and sugar quickly and reliably, and the lumps cannot be efficiently crushed in a short time.

[0009]

DISCLOSURE OF THE INVENTION The present invention is intended to provide a cooking and stirring machine exclusively for custard cream, which is useful for solving such a problem. Due to its constitution, a pot set in a gas pot and its pot are provided. It is composed of a mixer facing the inside of the pot, and is made from a non-heat storage heat insulating material that easily heats and cools the gas pot, while the mixer is attached to a non-stick rotary vane located at the center of the pot and its rotation. As a wire beater for eliminating lumps that revolves around the blade and rotates around the blade, the custard cream raw material stored in the pot is boiled and cooked by a direct gas flame, and the rotating blade and wire beater are used. It is characterized in that it is set to stir by.

[0010]

According to the above-mentioned constitution of the present invention, the gas kettle is made of a non-heat storage heat insulating material which is easy to heat and cool.
In addition to being cooked by the direct fire of the gas, the center of the pot also has a rotating blade to prevent charring, so its heat power is strengthened to a much higher temperature than the conventional steam type. Despite being able to do so, it is possible to reliably prevent the burning of the raw material on the bottom of the pan, and it is possible to produce a high-quality delicious custard cream, and at the same time, its work efficiency and energy saving effect are remarkably excellent.

Further, since a wire beater for resolving lumps that revolves around the rotary blade as it rotates is also exposed to the periphery of the rotary blade, a stirring action such as whipping of the wire beater causes It is possible to promote the familiarity of egg yolk and soft flour with milk and sugar, and it is possible to quickly and efficiently eliminate the unique solidification of the egg yolk and soft flour. , Can be finished easily.
