In recent years, a method of food processing using underwater shock wave has been investigated. The underwater shock wave is generated by high voltage and large current gap discharge in water, and it is used for food processing in the present investigation. When the underwater shock wave is loaded on the food, the food cells are momentarily broken. Therefore, the food becomes soft, and possible to squeeze water easily. Also, seasonings can be penetrated inside of the food. The improvement of absorbing seasonings for the shock processed foods mainly on Japanese radish is reported in this paper.

The Relationship

When an explosive in water is exploded, shock wave from the explosive propagates in water as underwater shock wave. Using a detonating fuse as an energetic source, an oblique underwater shock wave with high pressure is obtainable and possible to be utilized for various applications. It is expected that the use of water can inhibit the heating effect on the shock processed sample. In the present research, the authors are intended to use underwater shock wave for the food processing. After loading underwater shock wave against some foods, it is expected to show some advantageous effects for the food processing, such as, softening, improved permeability, and grinding foods. However, such advantageous effects are changed depending upon the condition of the received food. In this research, the foods containing high amount of water were treated by the underwater shock wave. Japanese radish and apple were used as food samples. The change in their hardness, permeability and so on were measured. These results were compared with the control sample in which the underwater shock wave was not applied.

Underwater Shock

The underwater shock-wave phenomenon has been applied in various fields such as manufacturing and food processing and was investigated using many experimental and numerical analyses in the past. An underwater shock-wave is produced by various methods, e.g., underwater wire explosion and pulse-gap electrical discharge. Therefore, clarifying the shock characteristics depending on the stored electrical energy, wire dimension and material is extremely important. However, predicting the pressure and its distribution induced by underwater electrical wire explosion is hard because the phenomena associated with an elementary process are significantly complicated. In this study, to predict the discharge characteristics induced by underwater electrical wire explosion, numerical simulation based on the “simplified model of underwater electrical discharge” was performed. The numerical results show good agreement with the experimental ones.

Institute Of Technology

The National Institute of Technology, Okinawa College (OkNCT) has developed a food processing machine that generates underwater shock waves through wire electrical discharge. The machine can used for sterilization, milling flour, softening, and extraction among others. In this study, we experimentally examined the conditions for food softening using pork as the food material in experiments. Softness was revealed to be related to the distance of shock wave generation point from meat and the number of shockwave processing.

The underwater shock wave has been studied in the various fields. The application of this method can be used for a molding machining, a welding and an embossing in the metal processing [. Moreover, this processing method can be used for a pulverizing, a softening, and a sterilization in the food processing. The aim of this research is to make the rice powder using by the underwater shock wave without generating of heat [. Although the underwater shock wave is generated using an explosive, the handling of the explosive is extremely accompanied by danger. Therefore, we developed the electric discharging device made to generate the underwater shock wave. It is easier to carry on the experiment using this device than the experiment of an explosive. We developed a pressure vessel for generating the underwater shock wave in various fields. The developed pressure vessel has been improved by our research group. The pressure vessel made to generate the shock wave is manufactured from a new concept, and the coaxial cable is used for wiring of the device.

The high energy generated from electric pulsed power has various applications. We investigated the underwater shock wave generated by the metal wire explosion and the electric discharge of electrode using high voltage impulsive current. This investigation was performed using optical observation, pressure measurement and current measurement. In the case of metal wire explosion, the velocity, pressure and the current value of underwater shock wave obtained from the experimental data is proportional to the electric resistance rate. In the other case, the discharge from the electrode, the velocity of the underwater shock wave generated by the discharge of electrode with metal wire explosion is faster than the underwater shock wave generated by the discharge of the electrode without metal wire.

We are developing the food processing system by using the underwater shock wave. The effect of the underwater shock wave on the pressure in the vessel is the important factor for food processing system in this research. The purpose of this study is to research the behavior of the underwater shock wave in the enclosed vessel to investigate the influence of the contour of the elliptical vessel on the pressure. In this research, we used the elliptical shape for the vessel and the explosive was used to generate the shock wave. Numerical calculation was carried out by using LS-DYNA. The ratio of the length of the major axis to minor axis of the elliptical were changed, as a main parameter. As a result, it was found that underwater shock wave was generated and propageated in the elliptical vessel following the explosion. The underwater shock wave was coverged at the focal point. At the same time, the pressure was increased by the coverged underwater shock wave at the focal point in the all elliptical vessels. It was also found that the peak pressure at the focal point was determined by the contour of the elliptical vessel.
