DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a pair of upper and lower electrode bodies are filled in an insulating container and elastically connected in an insulated state via a salt-containing water contact body. Pressurized food materials can be easily and quickly sterilized by heat sterilization by simply inserting a plug and energizing the food materials.It also reliably prevents the juice exuding from the food materials from flowing out during energization processing.At the same time, the temperature sensing needle allows accurate detection of ripening temperature at all times,
The present invention relates to a method for producing electrically processed foods that can continuously produce electrically processed foods with constant quality.

Conventionally, raw food materials made of agricultural and livestock products, marine products, or other materials are quickly sterilized by heat sterilization using the Joule heat generated by current resistance, and raw food materials are heated on both sides in order to obtain flavorful electrically processed foods. A method for producing packaged food in which the food material is filled into an open insulating container, and then the filled food material is pressed between a pair of left and right electrode bodies through a salt-containing electrical contact body while energizing is applied. For example, it is described in Japanese Patent Publication No. 55-3219 and is well known.

By the way, in the conventional manufacturing method of this type of packaged food, in order to perform energization processing on the filled food material under pressure, it is necessary to move the pair of left and right electrode bodies back and forth each time. As a result, the structure of the entire manufacturing apparatus becomes complicated and expensive. In addition, the filled food material contains a large amount of juice to make flavoring and energization processing easier, and this juice oozes out from the food material during the pressure energization processing and then becomes insulating. Since the liquid leaks out from the container and adheres to various parts of the equipment, cleaning work is required to wipe off the spilled liquid every time during energization processing, which significantly reduces work efficiency. Not only do electrical leakage accidents sometimes occur, causing unexpected malfunctions, but also problems such as the inability to continuously obtain electrically processed foods at a constant sterilization temperature due to the inability to carry out accurate electrical processing. had.

The food material is filled into an insulating container while being squeezed by the body, and the pinching and filling action of the food material by a pair of electrode bodies is easily and accurately performed without using any moving device, thereby simplifying the entire manufacturing equipment. The object of the present invention is to provide a method for producing electrically processed foods that can easily achieve the following.

Another main object of this invention is that by simply inserting a plug into the socket provided on the upper electrode body for squeezing the food material, the pressure can be uniformly applied between the upper and lower electrode bodies, and the food material can be quickly squeezed. To provide a method for producing an electrically processed food by which the electrically processed food can be easily and continuously produced by sterilizing the electrically processed food.

Another main object of this invention is to
All of the juice that oozes out from the food material is caught by the lower electrode body and stored in the juice storage chamber provided between the insulating container and the lower electrode body, thereby preventing electric leakage accidents, malfunctions, or unsanitary accidents due to the leakage of juice. It is an object of the present invention to provide a method for producing an electrically processed food, which can prevent such a situation and efficiently produce a uniform electrically processed food at all times.

If... is installed, a large number of electrically processed foods can be manufactured at once, and mass production can be achieved with simple equipment.

In short, the present invention provides a food material A filled in an insulating container 1 with both upper and lower surfaces open, which is placed on the opposite surface side via salt-containing water contact members 2 and 3, and is elastically insulated. After the upper and lower electrode bodies 4 and 5 are pinched together, the plug 18 is inserted into the socket 9 provided in the upper electrode body 4, and electricity is applied between the upper and lower electrode bodies 4 and 5 to remove the food material. Food material A is heated to sterilize A, and during electrical processing, food material A is
The more seeped juice is received by the lower electrode body 5 and stored in the juice reservoir chamber 12 provided between the lower electrode body 5 and the insulating container 1, so that the filled food material A
There is no need for a device that reciprocates the pair of upper and lower electrode bodies 4 and 5 for each processing operation in order to carry out electrical processing under a pinched state, and the manufacturing apparatus is greatly simplified.
Perhaps because of the ability to reduce product costs, when energizing, simply inserting the plug 18 into the socket 9 quickly sterilizes the food material A evenly pressed, making it possible to efficiently produce homogeneous energized processed foods. In addition to being easy to manufacture, even if the food material A expands during electrical processing, the elastic movement of the pair of upper and lower electrode bodies 4 and 5 automatically suppresses the expansion, thereby preventing the food material A from accidentally expanding and bursting. At the same time, the juice exuded from the food material A during the electric processing is stored in the juice storage chamber 12 without flowing out to the outside. Prevent electrical leakage accidents caused by wiping and cleaning of spilled juice, such as those seen in manufacturing equipment, as well as injury accidents caused by electrical leakage.
Not only can the manufacturing work be carried out safely and hygienically, but also the plug 1 inserted into the socket 9.
Since the temperature detection needle 21 was provided at 8, food material A
As a result, it is possible to accurately detect the temperature of heat sterilization of food material A, and as a result, products that have been heat sterilized at a predetermined temperature can be continuously provided, and the filling and squeezing work of food material A and the energization work are extremely easy, making mass production possible. This has the effect of making it possible to
