Description

Electric field treatment heating processing equipment

Technology field

As a food processing apparatus, a fryer that manufactures deep-fried food mainly using oil is known.
The present invention relates to an electric field processing heat processing apparatus that performs cooking by applying an electric field to a fryer, particularly food.

In electric field treatment heating processing, the constituent molecules inside the treatment are polarized along the electric force line direction by an electric field generated by applying an alternating voltage, and the polarized constituent molecules are repeatedly aligned and aligned in the electric force line direction. By gradually aligning the arrangement of the constituent molecules and removing impurities mixed between constituent molecules, or by actively supplying ions to the constituent molecules and simultaneously flowing an induced current to the constituent molecules, Improves various effects.

In WO2004 / 110179 by the present inventors, a plurality of electrodes have the same polarity instead of the conventional electric field treatment heat processing apparatus in which an alternating voltage having a positive potential is applied to one electrode and a negative potential is applied to the other electrode. An electric field treatment heating processing apparatus is described in which an electric field is applied to generate an electric field, and an alternating voltage having a different polarity is applied to an infinitely far space, thereby processing an object to be processed.

Compared with the conventional electric field treatment heating processing device that generates an electric field by applying an alternating voltage of different polarity, the electric field treatment heating processing device that applies an alternating voltage of the same polarity has a uniform electric field formed by a plurality of electrodes. Thus, the object to be processed can be processed efficiently.

In this electric field treatment heating processing apparatus, since alternating voltages having the same polarity are applied to a plurality of electrodes, the electric field lines directed from each electrode to which a positive potential is applied to the infinity space, or vice versa, are negative from the infinity space. Since electric lines of force directed to each electrode to which a potential is applied are superimposed on the workpiece, more electric lines of force pass through the workpiece. For this reason, the object to be processed is placed in a strong electric field, and has a higher potential than that of the prior art.

Then, along with the reversal of the applied alternating voltage, the workpiece undergoes reversal from the positive high potential to the negative high potential, and further from the negative high potential to the positive high potential, and the alternating alignment is aligned at the polarized constituent molecule level. While being repeated, the material to be treated is reformed and heated.
Compared to the case where the conventional technique simply uses an alternating electric field generated between electrodes of different polarities, the alternating orientation alignment is performed at a high potential, so that the object to be processed can be efficiently modified and heated.

In a conventional electric field treatment heat processing apparatus, a high voltage is directly applied to a food as an object to be processed from a conductive shelf, and the reforming and heat treatment is performed by a potential difference between the food to which the high voltage is applied and the ground plane. Is done. In other words, an alternating voltage of different polarity is applied to the ground plane and the conductive shelf (the food placed).
Examples of the alternating high voltage fine current supplied are 3000 to 10000 V, 10 to 100 mA.

FIG. 12 shows a prior art electric field treatment heat processing apparatus described in WO2007 / 124619 (Japanese Patent Publication No. 2010-512172). This electric field treatment heat processing apparatus is an improvement of the electric field treatment heat processing apparatus disclosed in WO 2004/110179.
This electric field processing heat processing apparatus handles a fluid having a low dielectric constant such as oil.

Consists of no electric field forming power supply.

The cylindrical electrode 103 is disposed so as not to contact the pan-shaped electrode 110.
The electric field forming power supply device applies an alternating voltage of the same polarity to the cylindrical electrode 103, the lower electrode 104, and the upper electrode 105.
The pan electrode 110 is connected to the ground 102.

The pot-shaped electrode 110 is filled with oil, food is stored in the electric field processing region 106 composed of the lower electrode 104 and the upper electrode 105, and the upper lid electrode 105 is lowered using the driving device 107 and exists in the electric field processing region 106. An electric field is applied to the oil to be processed and the food to be processed, and the electric field processing is performed.

WO2004 / 110179 WO2007 / 124619

When food is heat-treated with oil, frying chips, conductive substances, polar substances, etc. are generated and adhere to the inner wall surface of the grounded pan-shaped electrode of the electric field treatment heating processing device or form a chain-like substance. May cause a general leak condition.
The first problem of the present invention is to prevent the occurrence of an electrical leakage state.

The second subject of the present invention is to continuously stabilize the generation of these harmful substances and the promotion of their decomposition.

The third problem is to continuously stabilize the shortening of the frying time, the decrease in the oil absorption rate of the fried food, the increase in the umami component, and the like.

In order to solve these problems, the present application provides an invention having the following configuration.
(1) An oil-permeable bottomed storage electrode for storing a workpiece is disposed in an oil-impermeable bottomed pot-shaped electrode for storing oil, the pot-shaped electrode is grounded, and the storage An electric field treatment heating processing apparatus for applying an alternating high voltage electric field to a workpiece accommodated in oil and applying an alternating high voltage electric field to the workpiece to perform processing / heating, the pan-shaped electrode and the accommodating electrode An electric field treatment heating apparatus in which an oil-permeable bottomed floating electrode is disposed between the floating electrode, the pan-shaped electrode and the accommodating electrode are insulated, and the floating electrode is not electrically connected.
(2) An electric field processing and heating apparatus in which an insulating member is attached to the upper end of the accommodation electrode or an insulating process is performed by applying an insulating paint.

Therefore, an electrokinetic surface is regularly and continuously formed at the interface between the oil and the fried food in the containing electrode to which a high voltage weak current of the same polarity is applied, and the electrode is continuously and regularly formed between the two electrodes. Charge exchange transfer also occurs. Furthermore, the discharge from the tip of the entire peripheral wall of the storage electrode toward the lid of the floating electrode is also suppressed.

Further, the movement and adhesion of the floating electrode and the pan-like electrode to the entire peripheral wall surface, the formation of the chain shape, etc. are quickly cut off, and the electric leakage state can be suppressed. Furthermore, the stability of the electric field strength stabilizes the amount of electron accumulation inside the fried food.

According to the electric field treatment heat processing apparatus according to the present invention, the polar compound material is converted into a polarization aggregated precipitation lowering substance, and moisture / volatile substances are promoted to evaporate and activated. The oil in the area is stably controlled, and the electric field treatment effect on the fried food is also highly efficient.

The oil absorption rate is reduced by 20%, and when the TMP is 17.5% or less, the use time can be extended by 2.2 times.
