  On the other hand, it has been proposed that foods, chemicals, raw materials for drugs, industrial materials, and the like be subjected to various treatments using shock waves. That is, if a shock wave is used, a food or the like can be easily softened or pulverized or subjected to other processing in a short time without impairing nutritional components and active ingredients.

However, for example, when using a discharge crushing device that generates a shock wave by vaporizing the discharge between electrodes or thin metal wires, and the shock wave is directly collided with food via the electrolyte, the action of electric ions generated with the shock wave In addition, redox reaction by electrolysis occurs in foods and the like. As a result, there is a problem that the taste, color, flavor and the like of the food are impaired. Although shock wave treatment for food is expected to be very useful, it is strongly desired to avoid the above disadvantages.
Similarly, even if the object to be treated is a medicine other than food, a raw material of medicine, or an industrial material, a situation in which the quality of the object is impaired must be avoided.
In the processing as described above, it is sufficient that only the shock wave reaches the object to be processed from the shock wave generation unit, and it is excluded that the object to be processed such as food is not subjected to secondary unintended processing accompanying the processing by the shock wave. It is necessary to.
In addition, when a discharge device that generates a shock wave by vaporizing a thin metal wire connected between the electrodes must be newly replenished, there is a problem that hinders the processing by a quick and smooth shock wave.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a shock wave processing method and apparatus capable of suppressing a secondary unintended process associated with a shock wave process.
In addition, when shock waves are generated by electric pulses, and processing such as softening and pulverization of foods, etc. is performed by the shock waves, shock wave processing that prevents degradation of the quality of the workpiece due to electrolysis or the like It is an object to provide a method and apparatus.
Further, it is an object of the present invention to make it easy to replenish a thin metal wire that is consumed every time a shock wave is generated, or to replace an electrode that has been consumed due to a considerable number of discharges, thereby enabling a quick and smooth treatment with a shock wave. .

In order to achieve the above object, the present invention is configured as follows. That is, in a shock wave processing method for executing processing on a workpiece by a shock wave generated from a shock wave generation unit,
A diaphragm is provided between the shock wave generating section and the object to be processed to allow a shock wave to pass while blocking a substance generated when the shock wave is generated, and the shock wave reaches the object to be processed through the diaphragm. It is characterized by.
The shock wave generating unit may be a known unit that generates a shock wave, for example, by explosive explosion, discharge, convergence of laser light, a piezoelectric element, a giant magnetostrictive element, or the like, in addition to electrodes.
There are various types of substances that accompany the generation of shock waves, such as gas and soot that accompany the combustion of explosives, metal ions and metal fragments that are generated as a result of evaporation or rupture of part of the electrodes and fine metal wires. .
The diaphragm can be formed of a flexible synthetic resin such as a silicon resin or a polypropylene resin. The thickness is preferably about 0.1 mm to 1 mm in order to ensure flexibility.
ADVANTAGE OF THE INVENTION According to this invention, in addition to the target process by a shock wave, it can suppress that a secondary unintended process is given to a to-be-processed object.
According to another aspect of the present invention, there is provided a shock wave processing method in which a discharge wave between electrodes is applied to a transmission medium to generate a shock wave, and the object to be processed is processed by the shock wave between the electrode and the object to be processed. In addition, a diaphragm that blocks at least metal ions among substances generated in response to the generation of the shock wave may be disposed, and the shock wave may reach the object to be processed through the diaphragm.

  Discharge energy can be generated by instantaneously discharging accumulated charge energy charged in a capacitor or the like between the electrodes. The electrode can be formed of a commonly used material such as aluminum, nickel, copper, or tungsten. In addition, when using what connected the metal fine wire between electrodes, the thing of the diameter of about 0.2 mm to 1 mm which consists of aluminum, copper, etc. can be used as a metal fine wire, for example. Then, the metal thin wire is instantly melted and vaporized by the discharge, and expands to a metal vapor volume several tens of thousands of times to generate a shock wave.

  At this time, the shock wave propagates through the transmission medium and reaches the object to be processed. However, due to the discharge between the electrodes, the electrodes are consumed, or many metal ions are generated in the transmission medium as the fine metal wires evaporate or break. Therefore, in order to prevent the object to be processed from being electrolyzed, a diaphragm is provided so that only the shock wave reaches the object to be processed. In addition, it is not only metal ions that are prevented from reaching the object to be processed by the diaphragm, but also includes other substances (metal pieces, etc.) that accompany the generation of shock waves.

Although the material of the said diaphragm is not specifically limited, Since a hard thing is easy to be destroyed with a shock wave, it is preferable to form with a flexible synthetic resin, for example. For example, it can be formed of silicon resin, polypropylene resin, or the like. Its thickness is 0.1 m to ensure flexibility
m to about 1 mm is appropriate.
Moreover, the said diaphragm may be closely_contact | adhered to to-be-processed object, and the state which wraps especially to-be-processed object may be sufficient.

In addition, the space between the shock wave generator and the object to be processed needs to be filled with a pressure transmission medium such as a liquid or a gel-like resin. This transmission medium can be an incompressible fluid such as a liquid. In the present invention, the outside of the diaphragm, that is, around the place where the workpiece is placed is filled with a liquid such as water. A highly compressible gas is difficult to transmit pressure and is not suitable.
Here, water or the like is for transmitting a shock wave (shock wave transmission medium), in other words, for transmitting pressure associated with the shock wave (pressure transmission medium). As the transmission medium, an incompressible fluid such as a liquid can be used, and includes a wide range of liquids and gels in addition to water. For example, in addition to water, liquid nitrogen, liquid carbon dioxide, and other liquids having a low boiling point can be used. The use of such a liquid is effective in an environment of 0 ° C. or lower, or when an object to be processed is held at a low temperature of 0 ° C. or lower.
Further, it is possible to use a liquid such as fruit juice, which is an object to be processed, a solid, or a powder itself as a transmission medium. For example, a liquid (for example, fruit juice such as apple juice or coffee extract) or a powder (for example, coffee beans or cereal powder) is placed in the processing object storage unit, and the liquid in the processing object storage unit It can be considered that the object to be processed is processed by transmitting the generated shock wave using the powder itself as a transmission medium. In such a case, it is not necessary to use a transmission medium such as a liquid in addition to the object to be processed, and the implementation is easy. Is possible.
As another aspect, the tube through which the object to be processed passes is disposed in the object to be processed container filled with the transmission medium, and liquid or the like is supplied from the outside into the object to be processed container through the tube. It can also be recovered after processing. Such a processing system can also realize efficient processing.

An apparatus for carrying out the above method is as follows.
That is, a shock wave processing device that applies discharge energy between electrodes to a transmission medium to generate a shock wave, and processes an object to be processed with the shock wave,
A workpiece storage unit is provided for processing by shock waves,
Between the workpiece stored in the workpiece storage section and the shock wave generating section including the electrode,
It is characterized in that a diaphragm that allows a shock wave to pass through but does not pass through a substance that accompanies the generation of the shock wave, such as metal ions, is arranged.

The apparatus may include a replacement cartridge including an electrode part including a positive electrode and a negative electrode and an electrode support part supporting the electrode part as a shock wave generating part.
In addition, the electrode portion may be one in which a thin metal wire is connected between the positive electrode and the negative electrode.
The said electrode should just contain a positive electrode and a negative electrode, and may provide the some positive electrode and negative electrode other than what is provided with a pair of positive electrode and negative electrode. In particular, in the case of an electrode using a fine metal wire, if a plurality of electrodes are provided in the cartridge and a plurality of fine metal wires are previously installed between the electrodes, a shock wave can be generated multiple times. There is an advantage that the exchange frequency is reduced.

  You may make it perform the process by a shock wave in multiple times with respect to the to-be-processed object accommodated in the said accommodating part. In such a case, it is preferable that the shock wave generator can generate the shock wave a plurality of times.

The shock wave generation unit includes an electrode unit, an electrode support unit that detachably supports the electrode unit on a shock wave processing device, and a diaphragm that covers at least the space including the electrode unit, and the electrode unit includes a shock wave process It can be a cartridge type that is mounted so as to face the workpiece storage part of the apparatus.
In this way, even if the electrodes are consumed or the diaphragm deteriorates due to the occurrence of discharge and shock waves, and these need to be replaced, the entire cartridge can be removed and easily replaced with a new cartridge. Can be carried out. Further, when using an electrode portion of a type in which fine metal wires are connected between the electrodes, after the shock wave is generated by the discharge and the fine metal wires are vaporized, the entire cartridge can be quickly replaced with a new one. In addition, when a diaphragm is separately provided in the workpiece storage part, the cartridge may include an electrode part and an electrode support part that supports the electrode part, and may not include the diaphragm.

  The object to be treated in the method or apparatus of the present invention is, for example, a food, drug, or the like intended to be softened, powdered, or porous (to form a space, a fine hole or a crack inside so as to be easily crushed), etc. Raw materials for chemicals, industrial materials, etc. In the processing method aiming at softening, the softening may be performed while holding a predetermined shape of food, medicine or the like. Examples of foods and medicines suitable for such treatment include apples, pineapples, winter potatoes, radishes, ginger, potatoes, potatoes, sweet potatoes, garlic, tomatoes, yuzu, passion fruit, dragon fruit, burdock, bamboo shoots, prunes, sugar cane Or side dish etc. are mentioned.

In addition, as foods, chemicals, etc. that are subject to processing for the purpose of pulverization, porous formation, etc., for example, tea leaves, red beans, green coffee beans or roasted beans, walnuts, rice wheat and other grains, shiitake, etc. Is mentioned. Furthermore, liquids such as fruit juice and coffee extract, coffee beans, and other powders can be processed.
By the said process, the taste and flavor of a foodstuff may be able to be changed, and the bactericidal effect with respect to a to-be-processed object can also be anticipated.

In the treatment method of the present invention, a shock wave may be applied to a food or the like brought into contact with the liquid to soften the food or the like and simultaneously allow the liquid to penetrate.
Moreover, in the processing method aiming at softening, the food may be softened by applying a shock wave, and then the food may be squeezed, or a liquid may be injected into the food. Is possible.

Further, it may be softened while maintaining a predetermined shape. The “predetermined shape” means not only the shape (original shape) before giving a shock wave, but also the shape that can be maintained for a certain period even if it is slightly deformed. Including.
“Softening” means that the hardness of the food is reduced partially or entirely as compared with the state before applying the shock wave.

  Moreover, the cell by which the cell wall was destroyed increases by the pressure by a shock wave being provided. In such a case, when the pressure by the shock wave is applied, the extraction ratio of the specific nutrient component is increased as compared with that before the pressure is applied.

According to the present invention, a desired treatment such as softening or pulverization can be performed in a short time by applying a shock wave to foods, medicines, raw materials of medicines, etc. However, it is not damaged due to heat or the like.
Moreover, since it processes by provision of a shock wave, in the case of processes, such as fruit juice extraction in a fruit, extractability can be improved. At this time, the pores in the fruit expand and the proportion of the pores increases, so that the permeability is improved simultaneously with being softened.

  Furthermore, when the cell wall of a cell is destroyed, since the specific nutrient component in a cell is discharged | emitted out of a cell, the extraction efficiency of a nutrient component improves.

According to the present invention, the diaphragm suppresses adverse effects such as contamination of foreign matter into the object to be processed and electrolysis of the object to be processed, so that the shock wave treatment is suitably applied to foods, drugs, raw materials for drugs, and the like. be able to.
In addition, if the shock wave generating unit in the shock wave processing apparatus is a replacement cartridge including an electrode unit including a pair of positive and negative electrodes and an electrode support unit that supports the electrode unit, the replacement can be easily performed. , Efficient processing becomes possible.
Furthermore, since the shock wave generating portion can be kept from being shut off from the outside by providing the diaphragm, it is possible to protect the electrode and the like from external intruders such as impurities and suppress deterioration and the like.

Hereinafter, embodiments of a processing method and a processing apparatus using a shock wave according to the present invention will be described with reference to FIGS.
(Embodiment 1)
FIG. 1 shows the basic structure of the processing apparatus of the present invention. This device generates a shock wave by an electric pulse in order to give a shock wave to food or the like. Here, although it demonstrates as an apparatus which made food the object of processing, a to-be-processed object is not restricted to this, A chemical | medical agent, a raw material of a chemical | medical agent, an industrial material, etc. may be sufficient.

As shown in FIG. 1, the pressure-resistant structure device has a box shape with an open top surface, and a processing object storage unit 10 for a processing object such as food by shock waves is provided therein, and an upper lid 11 that can be freely opened and closed. Thus, the upper surface opening is closed. A shock wave generator 12 is attached to the upper lid 11 above the workpiece storage unit 10. In this example, the shock wave generator 12 is of the cartridge type shown in FIG. 2 and has a structure that can be replaced quickly. The shock wave generating unit 12 includes an electrode unit 1 that generates a shock wave in the workpiece storage unit 10. Since this type includes the electrode part 1 that generates an electric pulse, the electrode support part 13 that supports the electrode part 1, and the diaphragm 30, a considerable number of times between the anode 1a and the cathode 1b (FIG. 2). Even when these are consumed by electric discharge, the electrode part 1 can be immediately replaced without opening the upper lid 11.
Further, when the diaphragm 30 is deteriorated or damaged due to use, it can be replaced in the same manner. The diaphragm 30 may not be formed integrally with the shock wave generating unit 12 but may be installed in the workpiece storage unit 10, and the shock wave generating unit 12 may include the electrode unit 1 and the electrode support unit 13. .

The shock wave generating portion 12 is attached to a mounting hole 11 a provided in the central portion of the upper lid 11 by a screw portion 13 a of the electrode support portion 13. The mounting hole 11 a is provided so as to penetrate the upper lid 11 in the vertical direction, and is formed in a tapered shape having a slightly smaller diameter toward the lower side (the workpiece storage unit 10 side). It is said. In this way, the electrode support portion 13 can be fixed at a predetermined position and can be pulled upward. In this case, a buffer body such as rubber is provided in the mounting hole 11a, and the buffer body and the screw portion 13a of the electrode support portion 13 are in close contact with each other in the mounting hole 11a, so that the airtightness of the workpiece storage unit 10 is ensured. So that However, if necessary, it is preferable to further provide another stopper such as a concave-convex fitting portion or a screw so that the electrode support portion 13 is held at a predetermined position by the screw portion 13a.

  The shock wave generating part 12 is a long rod-shaped body composed of the electrode part 1 and the electrode support part 13, and the positive electrode 1a and the negative electrode 1b of the electrode part 1 are opposed to one end on the workpiece storage part 10 side. Is provided. The electrode portion 1 is covered with a diaphragm 30. The upper end of the diaphragm 30 is fixed to the electrode support portion 13, covers the electrode portion 1 without a gap, and contains water W as a transmission medium existing around the electrode portion 1. Note that the shock wave generated in the electrode unit 1 can pass through the diaphragm 30, but the water W does not pass through the diaphragm 30.

The electrode support portion 13 is insulated and separated into a positive contact portion 6 and a negative contact portion 7 through an insulator 5 at a threaded portion 13a. The positive contact portion 6 and the negative contact portion 7 include an electrode. The positive electrode 1a and the negative electrode 1b are connected to each other. The positive contact 6 and the negative contact 7 are supplied with the current of the high voltage generator 20 shown in FIG.

  In the workpiece storage unit 10, the outside of the diaphragm 30 is filled with water W. This water W is for transmitting a shock wave (shock wave transmission medium), in other words, for transmitting pressure accompanying the shock wave (pressure transmission medium). As the transmission medium, an incompressible fluid such as a liquid can be usually used, and a wide range of liquids are included in addition to water. For example, liquid nitrogen or the like can be used, and when a fruit is to be processed, its fruit juice can be used as a transmission medium.

  The electrode part 1 is covered with a diaphragm 30 made of silicon resin. The diaphragm 30 covers the electrode part 1 without a gap, and includes water W as a transmission medium existing around the electrode part 1.

  The shock wave generated by the discharge between the electrodes of the shock wave generating unit 12 as described above is a strong pressure change wave that propagates at a high speed (a speed exceeding the speed of sound) in the transmission medium, and includes physical properties such as pressure, temperature, and density. It has the property of changing a factor instantaneously and abruptly. The pressure associated with the shock wave, that is, the pressure applied to the food F using the shock wave can be freely set in a wide range, but is usually used within a range of, for example, about 5 MPa to 500 MPa.

In addition, when a shock wave is generated, metal ions move in the water W toward the object to be processed along with the shock wave by the discharge. The metal ion dissolved in the water W becomes a hydroxide by hydrolysis with the water W or a reaction with the hydroxide ion (OH-), and an oxidation-reduction reaction for electrolyzing the object to be processed occurs. In particular, if the object to be treated is a food, the taste, color, flavor and the like may be impaired by such an action, and even a chemical or the like may cause quality deterioration.

  Therefore, only the shock wave reaches the object to be processed by the diaphragm 30 separating the object to be processed and the electrode part. The diaphragm 30 is made of silicon resin, and the thickness is suitably about 0.1 mm to 1 mm. The diaphragm 30 may be a flexible synthetic resin film that can be attached to and detached from the shock wave generator 12. In this way, the diaphragm can be exchanged. Further, the diaphragm may be in the form of a synthetic resin film that individually wraps each food F and adheres closely to the food F.

On the other hand, the high voltage generator 20 that supplies a high voltage to the electrode unit 1 provided in the shock wave generator 12 includes a charge circuit 21 and a capacitor 22 in order to supply high voltage energy as shown in FIG. It is configured. The capacitor 22 is connected in parallel to the output stage of the charge circuit 21. The high-voltage generator 20 is connected to a power source 24 such as a commercial power source or a generator. If the power source is an alternating current, it is converted into a direct current and used.
In the apparatus shown in FIG. 1, a plug 25 to an outlet such as a commercial power source is connected to the high voltage generator 20, and a push button 23a for operating the switch means 23 is provided on the side.

A predetermined amount of charge is accumulated in the capacitor 22 at a high voltage (for example, 15 KV) by the charge circuit 21, and both terminals of the capacitor 22 are output terminals of the high voltage generator 20. The negative output terminal is connected to the negative electrode 1b of the electrode, the positive output terminal is connected to the positive electrode 1a of the electrode, and the switch means 23 is provided between the positive output terminal and the positive electrode 1a of the electrode. The switch means 23 can be constituted by a semiconductor switching element such as a thyristor, for example, for switching a high voltage current.

  When charge is accumulated at a high voltage in the capacitor 22 of the high voltage generator 20, if the switch means 23 is turned on (conductive state) via the push button 23a, the current accumulated in the capacitor 22 causes the switch means 23 to be turned on. It is discharged via and flows to the electrode part 1. Then, an inter-electrode voltage V is generated between the positive electrode 1a and the negative electrode 1b, and a shock wave is generated around the electrode portion 1 due to discharge between these electrodes. The shock wave energy at this time is transmitted to the surface of the part to be treated (food F), and the object to be treated is subjected to a predetermined treatment such as softening.

(Embodiment 2)

The shock wave generator 52 includes a positive electrode 51a and a negative electrode 51b of a pair of electrodes 51, and a metal thin wire 2 connected between both the electrodes 51a and 51b. The other parts except the electrode part 51 provided with the metal thin wire 2 are the same as those in the apparatus shown in FIG.

  The fine metal wire 2 has a diameter of 0.8 mm, for example, and can be formed of a metal such as copper or aluminum. Moreover, you may provide one or more electrode parts 51, In that case, the metal fine wire 2 is connected to each electrode, respectively.

Further, what is shown in FIG. 5 is a cartridge type shock wave generator 12 used in the apparatus shown in FIG. This type includes an electrode part 51 that generates an electric pulse, an electrode support part 13 that supports the electrode part 51, and a diaphragm 30, and after the metal thin wire 2 is vaporized by a high current load and a shock wave is generated, the electrode part 51 is a structure that can be easily replaced. The electrode support portion 13 is a long rod-like body, and is provided at one end on the workpiece storage portion 10 side so that the positive electrode 51a and the negative electrode 51b of the electrode 51 face each other. Is connected. The electrode portion 51 is covered with the diaphragm 30.
Note that the device shown in the second embodiment allows a high current generated by the high voltage generator 20 shown in FIG. 3 to flow between the positive electrode 51a and the negative electrode 51b, similarly to the device according to the first embodiment described above. A shock wave can be generated around the electrode portion 51 by discharging between the electrodes.

  Here, it is assumed that the object to be processed is preferably softened to be processed like an apple as an example of the food F. However, when the shock wave reaches the food F to be processed, the food F is caused by the shock wave. Softens. The reason for the softening of the food F is, for example, that after the bubbles are compressed in the cells or tissues in the food F in response to a sudden pressure change accompanying the shock wave, the cell membrane or cell wall in the food F is destroyed. It is assumed. For example, in the case of this apple, it is desirable to apply a pressure of about 12.6 MPa, more preferably 12.6 MPa or more and 182 MPa or less.

In addition, when softening fruits and vegetables such as apples while maintaining a predetermined shape, the pressure is preferably 12 MPa or more and 40 MPa or less. In the above processing, the shock wave can be given once or divided into a plurality of times.
After processing the food F, the processed food F may be further processed as necessary. Here, for example, the processed food (food that has been cut into pieces as necessary) is squeezed. Thereby, liquid components, such as fruit juice, are extracted.
It should be noted that various foods, medicines, and the like can be appropriately subjected to various treatments such as crushing or forming cracks and numerous holes.

According to the shock wave processing apparatus of the present invention, it can be transported because it can be operated by a commercial power source and can be relatively reduced in size, and the part including the electrode part can be easily replaced by making it a cartridge type. Become. Therefore, it can be installed not only in food processing factories but also in stores and homes. By using this apparatus, it is possible to easily provide fresh juice or the like on the spot.

  In addition, it is effective for protecting the electrode part if a diaphragm located between the electrode and the object to be processed is provided so as to block the electrode part from the outside. In particular, when using a cartridge type shock wave generator, the diaphragm wraps the electrode part, so that the electrode part can be prevented from being damaged during transportation and storage, and the electrode part can be protected from impurities entering from the outside. .
