Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an apparatus capable of heating and processing food materials in an electric current in a short time, and an apparatus capable of continuously performing electric heating treatment.

(Prior Art) Conventionally, a means for electrically heating a food material having fluidity has been used, but since copper, aluminum, iron or the like has been used as an electrode body, an electrolysis phenomenon occurs and corrosion of the electrode body occurs. There was a defect that the flavor of the food was deteriorated. JPA
In JP-A-58-28260, as a means for solving these drawbacks, an electrode plate is provided on the container body, and the frequency of the AC power source for direct energization is changed from 1000 Hz to 40 MHz to prevent electrolysis of liquid food during energization. , A method and an apparatus for heat processing are disclosed.

However, with the progress of the times, by using titanium or platinum as the electrode body, the drawbacks such as corrosion resistance and deterioration of food flavor have been solved.

[Problems to be solved by the device]

The present invention is an open fire, which is commonly used from this viewpoint.
Compared with heating methods such as steaming or indirect heating, the food material can be heated electrically by a simple and short time, and the temperature can be easily controlled by adjusting the power supplied. It is intended to provide an apparatus capable of continuously heating and processing a food material contained in a container.

(Means for Solving the Problems) The present invention provides one or more pairs of electrode bodies for electrically heating an object to be heated, inside the lid of a container having heat resistance and electrical insulation. The electrode body is connected and fixed to a conductive terminal exposed to the outside of the lid body, and the conductive terminal is
The lid body is configured to be applied from a lead wire for feeding, and the lid body is related to an electric heater which can be fitted to a container body filled with an object to be heated.
Furthermore, the present invention relates to a continuous electric heating device capable of continuously operating the electric heater to sequentially heat and process the object to be heated filled in the container body.

(Example) Next, this invention is demonstrated in detail based on an Example.
The lid 1 used in the present invention has heat resistance and electrical insulation. For example, a material such as PET (polyethylene terephthalate) or PP (polypropylene) having a certain degree of strength is suitable.

One or more pairs of electrode bodies 2 are grounded to the lid body, and titanium and platinum are optimally used for the electrode body. This is because materials such as aluminum, iron, and copper induce electrolysis and affect the corrosion of the electrode body and the deterioration of the flavor of food. The electrode body is connected and fixed to the conductive terminal 3 exposed to the outside of the lid body 1. The conductive terminal is connected to the lead wire 5 and relates to an energization heater configured to be energized. In this case, the opening of the energization heater can be closely fitted to the opening of the container body 4 containing the object to be energized, and at the same time, the electrode body 2 is connected to the container body 4 by the electrode body 2.
It comes into contact with the inner surface of the. As the container body 4, a material having heat resistance and electric insulation is used similarly to the material of the lid body. For example, the composition is PET, PP or a composite thereof. As for the shape, either a container or a bag can be used.

Here, as the current to be heated, it has fluidity including solid foods such as cooked rice, miso soup, oden, curry and meat sauce, as well as fluid foods such as kamaboko, sausage and ham. Any food is possible.

Next, when the container body 4 filled with the object to be energized is energized and heated for a certain period of time, it is separated from the energizer and used as it is, or it is sealed in a clean room and circulated at room temperature. Alternatively, it can be chilled food or frozen food.

In this case, if the whole or part of the periphery of the opening of the container 1 has a downwardly projecting portion 7 in the form of a film in order to make the heating process by the electric heating more effective, the heating during the electric heating is performed. It is possible to prevent the contents from swelling and spouting due to boiling, and it is possible to sanitarily cook and process. Further, by providing one or more small holes 8 on the upper surface of the lid body 1, it becomes possible to perform heat processing in a state in which the atmospheric pressure is not exceeded, but if a baffle plate is fixed on the small holes, pressure can be easily applied. Adjustment can be performed, and finer pressure adjustment can be performed by performing weight adjustment with a weight such as a weight on the baffle plate of the small hole.

However, in order to easily and accurately adjust the pressure, if a pressure valve is provided, cooking processing can be performed under pressure, which has the advantage of further shortening the cooking time. Here, the power supply can be an AC voltage of 100 to 200V.

The above is based on the batch process. However, when this is a continuous system, the endless belt 10 for continuously moving the lid 1, the drive device for the endless belt, and the object to be heated are charged. A frame 12 for moving the container body 4 and a drive device for the frame, and further has a structure in which a conductive rail 11 for energizing the conductive terminal 3 exposed to the outside of the lid 1 is provided. Become.

First of all, a large number of continuous electric heaters are attached to the supporting shaft.
It is fixed to the endless belt 10 via 15 and its rotational speed can be adjusted freely by a driving device (not shown). An endless belt 10 'is provided under the electric heater.
A large number of frames 12 fixed to the above can be adjusted and rotated by the driving device, and can be synchronized with the rotation speed of the electric heater. Therefore, when the container body filled with the material to be energized is fitted into the frame 12, the energizing heater rotating from above fits and comes into close contact with the container body, and the electric current is applied from the lead wire 5 to the conductive rail 11. Through the conductive terminal 3 to the electrode body 2, and the object to be heated is electrically heated for a certain period of time.

In this case, when it is desired to change the temperature history of the object to be heated, it is possible to divide the conductive rails at regular intervals and apply different voltages to the conductive rails. If the lid positioning roll 13 is provided as a vertical adjustment mechanism for the endless belt 10 connected to the electric heater so that the electric heater fits well with the frame 12, fine adjustment is possible.

〔effect〕

Since the device of the present invention has the above-mentioned configuration,
As long as it has fluidity and can be energized, it can be heat-processed in a wide range, and moreover, it can be cooked and processed in a shorter time in a simpler manner than the conventional direct heating / steaming or indirect heating method.

Furthermore, the device of the present invention can be used repeatedly, and it is not necessary to leave an accessory related to electric heating in the finished product. Further, by providing a small hole or a pressure valve in the device of the present invention, it is possible to discharge steam and aroma inside and adjust the internal pressure.

Further, in the food material continuous electric heating apparatus of the present invention, after the food material is supplied to the container, the container is fitted with the lid before the electric heating of the container, and the container is sequentially heated by electric current. Through the steps, a remarkable effect that the continuous three steps up to the step of separating the lid body from the container again can be continuously and automatically performed without using human hands is produced.
