Problems solved by technology

[0008] However, in the above fresh-keeping device, it is difficult to adjust the voltage value of the alternating voltage applied to the electrode portion.
Therefore, the intensity of the alternating electric field formed by the space potential generating device is also difficult to set according to the category, quantity or packaging status of fresh products, as well as the temperature or humidity in the fresh-keeping space.
Therefore, it is difficult to improve the effect of the alternating electric field on fresh-keeping treatment, or it is difficult to control the influence range of the electric field or adjust the size of the target space
[0009] Moreover, when the above-mentioned fresh-keeping device is equipped with a space potential generating device, it is difficult to improve the effect of the alternating electric field formed by the space potential generating device, or it is difficult to control the influence range of the electric field and adjust the size of the target space. Not only on the fresh-keeping device
For example, frying pans, water activation devices, breeding devices, drying devices, ripening devices, cultivation devices, or other processing devices equipped with space potential generating devices, the effect of the alternating electric field formed by the space potential generating devices is also difficult to achieve. Greater improvement, or it is difficult to control the influence range of the electric field and adjust the size of the target space

Embodiment approach 1

[0083] Firstly, one of the implementations of the present invention—the fresh-keeping device and the space potential generating device equipped with the fresh-keeping device will be described.

[0084]

[0085] First, the fresh-keeping device according to Embodiment 1 will be described. The fresh-keeping device according to Embodiment 1 is a device that forms an alternating electric field in the fresh-keeping space for fresh-keeping products, and keeps fresh-keeping products fresh in the fresh-keeping space where the alternating electric field is formed. Furthermore, the freshness keeping device according to Embodiment 1 is equipped with a space potential generator for forming an alternating electric field.

[0086] figure 1 It is a cross-sectional view schematically showing an example of the fresh-keeping device according to Embodiment 1. figure 2 It is a plan view schematically showing an example of a single electrode unit included in the fresh keeping device according ...

Embodiment example 6

[0192] For the chestnuts stored at 0°C in Example 6, the appearance of the three samples had no significant change after one month, with an average sugar content of 6.26, and the appearance remained unchanged after two months, with an average sugar content of 11.26.

[0193] For the chestnuts stored at -2°C in Example 6, the appearance of the three samples had no significant change after one month, with an average sugar content of 6.53, and the appearance remained unchanged after two months, with an average sugar content of 21.43. Figure 9 The photo on the right is one of 3 samples in this group after 2 months of preservation.

[0194] Through the above moldy situation and comparison Figure 9 It can be seen from the right and left photos of the chestnuts that the freshness of the chestnuts will be significantly improved when the chestnuts are preserved using the fresh-keeping device of Embodiment 1. And it can be seen from the difference in sugar content value that when che...

Embodiment approach 2

[0224]

[0225] Next, the fryer according to Embodiment 2 will be described. The fryer according to Embodiment 2 is equipped with a space potential generating device which is an electric field forming device for forming an alternating electric field.

[0226] Figure 14 It is a cross-sectional view schematically showing an example of a fryer device according to Embodiment 2. Such as Figure 14 As shown, the fryer device according to Embodiment 2 includes an oil tank 61 , an electrode part 2 and a voltage applying device 3 . Oil 61a is stored in the oil tank 61 . The electrode part 2 is installed in the oil tank 61 and is preferably immersed in the oil 61 a in the oil tank 61 . The voltage applying device 3 applies an AC voltage VL1 to the electrode portion 2 (see image 3 ), forming an alternating electric field in the oil tank 61. The space potential generating device 6 for generating an alternating electric field is constituted in the oil tank 61 by the electrode par...
