[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Referring to Figure 1 As shown, the embodiments of the present invention disclose a full-spectrum microenvironment freshness preservation system, including:

[0037] A pulsed electric field generator for generating pulsed waves with high voltage and narrow bandwidth, and forming a spatial matrix pulsed electric field environment through a resonance emission terminal;

[0038] A spectrum electric field generator for compiling sleep codes with different frequencies and voltages and converting them into electric field signals, and generating electric field waves with corresponding spectra after power amplification;

[0039] Multiple resonance emission terminals arranged in a matrix for uniformly diffusing the energy of the pulsed electric field and the spectrum electric field to the cargo storage space;

[0040] A two-way ion membrane packaging unit in the form of a packaging bag for isolating the freshness preservation object to form a stable microenvironment and storing it in the cargo storage space.

[0041] As Figure 1 shown, in the cargo storage area, a pulsed electric field generator can be used to form a spatial matrix through resonance emission terminals to form an alternating basic electric field environment within the matrix. An electric field spectrum generator is used to pre-compile sleep codes with different frequencies, and finally convert them into electric field signals, which form electric field waves after power amplification. The energy is diffused into the space by independent resonance emission terminals, thereby establishing a complex sleep electric field environment. In addition, the cargo is further packaged with a two-way ion membrane as a packaging bag to enclose the freshness preservation object to form a stable microenvironment, which can enhance the electric field, ventilate, moisturize, isolate pollution, and inhibit the growth of bacteria. It can effectively extend the freshness preservation period in the warehouse and at the same time extend the shelf life after leaving the warehouse.

[0042] The full-spectrum microenvironment preservation system provided by the present invention has an electric field environment composed of a pulse electric field generator, a full-spectrum electric field generator and a resonant transmitting terminal. The pulse electric field generator converts the electric signal into a high-voltage pulse to form a high-voltage narrow-bandwidth pulse wave. The instantaneous power is much greater than the average power, and the output of the high-intensity electric field is completed at extremely low energy consumption. The full-spectrum electric field generator compiles the electric signals of different frequencies and voltages into continuous pulses, forms electric field waves through direct current power loading, and uses different spectra for efficient hypnosis for different biological cell structures. The electric field signal eventually forms an electrostatic field of a certain intensity and frequency in space through the resonant transmitting terminal. Multiple transmitting terminals are arranged in a matrix manner, and electric field waves of the same intensity and frequency are synchronously emitted, forming a larger electric field intensity space after superposition.

[0043] The mechanism of action is as follows:

[0044] 1.1 Effect of pulsed electric field on water molecules

[0045] Under the action of continuously alternating electric field waves, the two hydrogen bond angles of water molecules shift, thereby changing the physical characteristics of water, which is reflected in the freezing point dropping to below -4°C, improved fluidity, and increased solubility. This process is also called water "activation". Activated water has an essential impact on the cell growth environment.

[0046] 1.2 The influence of electric field waves with specific spectrum on cells of higher organisms

[0047] When biological cells are continuously exposed to an electric field environment with a specific spectrum, the normal expression and transmission of genetic information are affected, and their life activities are inhibited. Under the influence of the external environment, they eventually enter a deep dormancy, and the organism as a whole appears to be in a state of "suspended death."

[0048] 1.3 Effects of alternating electric fields on lower microorganisms

[0049] The microbial cell structure is not complete and mature. Under the strong oscillating electric field, its basic life inheritance is disturbed, affecting its normal reproduction and growth. "Activated water" can change the osmotic environment of the cell membrane, causing it to twist, deform, and break, resulting in the inhibition of the growth of microbial cells or death.

[0050] 1.4 Effect of bidirectional ion membrane on preservation

[0051] The bidirectional ion membrane is a one-way breathable material that combines catalysis, antibacterial properties, and electric field loading. It can assist in the decomposition of organic gases and inhibit bacterial growth. Gas molecules can pass through, but water molecules cannot. After the preservation object is isolated by the bidirectional ion membrane, a stable microenvironment is formed that is not contaminated by external humidity and harmful substances, and has the effect of prolonging preservation.

[0052] Taking the preservation of fruits and vegetables as an example, after being encapsulated with a two-way ion membrane and placed in an electric field matrix, the refrigeration temperature is set at 2°C, the preservation period is extended to twice that of the traditional method, and the loss rate of nutrients is reduced by 30%.

[0053] In one embodiment, referring to Figure 2 as shown, the pulsed electric field generator includes an adjustable DC power supply, an inverter, and an amplifier connected in sequence;

[0054] The working principle and process of the pulsed electric field generator are described as follows:

[0055] 1. Adjustable DC power supply: It can constantly output a voltage of a set value; its input voltage is 220V AC, and after conversion, it outputs 12 - 36V DC voltage;

[0056] 2. Inverter: It converts direct current into pulsed current with a preset fixed frequency and waveform;

[0057] 3. Amplifier: It increases the spectral power of the pulsed current and transmits it to the emission terminal, and a spatial energy field is formed by the emission terminal;

[0058] The whole working principle is: Input 220V to the adjustable power supply DC, preset the output voltage of the adjustable power supply to be between 12 - 36V, the output is connected to the inverter, the inverter converts the direct current into a pulsed waveform, after increasing the input through the amplifier, one end is connected to the emission terminal; the electric field is diffused to the space through the emission terminal to form a stable basic electric field; the other end is grounded.

[0059] In one embodiment, referring to Figure 3 as shown, the full-spectrum electric field generator includes: a PLC, an intelligent DC power supply, an intelligent inverter, and an amplifier; the PLC is respectively connected to the intelligent DC power supply and the intelligent inverter; the intelligent DC power supply, the intelligent inverter, and the amplifier are connected in sequence;

[0060] The working principle and process of the full-spectrum generator are described as follows:

[0061] 1. Intelligent DC power supply: Connect to 220V AC power, and it can output any voltage according to PLC programming;

[0062] 2. Intelligent inverter: It can output any spectrum and waveform according to the PLC frequency modulation instruction;

[0063] 3. The amplifier increases the spectral power of the electric field and transmits it to the emission terminal, and a spatial energy field is formed by the emission terminal;

[0064] The whole working principle is: first, the 220V power supply supplies power to the intelligent DC power supply, converting the 220V AC power into 0-36V; the DC output voltage is controlled by the PLC: the output of the intelligent DC power supply is connected to the intelligent inverter, and the intelligent inverter converts the DC power into an output current of a specific waveform, and its waveform characteristics and spectrum are controlled by the PLC; the electric field spectrum output by the intelligent inverter is increased by the amplifier, one pole is grounded, and the other pole is connected to the transmitting terminal, and the energy is diffused into space through the transmitting terminal to form an energy field.

[0065] By controlling the output voltage of the intelligent DC power supply and the waveform of the intelligent inverter, a voltage value and a waveform combination form a unique electric field spectrum (sleep code). Through PLC programming control, various codes are sent out in a preset order. The output of the intelligent inverter is a constantly changing electric field spectrum, which eventually forms a spatial sleep environment through the amplifier and the transmitting terminal.

[0066] In one embodiment, Figure 4 As shown, the resonant transmitting terminal includes: a plurality of transmitting units distributed in an array; each transmitting unit includes an insulating protection tube 1, a transmitting electrode 2, a multi-way wiring valve 3 and a supporting tube 4, the transmitting electrode 2 is inserted into the insulating protection tube 1 and the gap between the transmitting electrode 2 and the insulating protection tube 1 is filled with an insulating filler 9; one end of the multi-way wiring valve 3 is sleeved on one end of the insulating protection tube 1; and the supporting tube 4 is fixed on the other end of the insulating protection tube 1.

[0067] In this implementation, multiple transmitting units can be arranged in a matrix to generate pulse resonance of electric fields of the same frequency and strength in space, thereby greatly enhancing the strength of the spatial electric field. In this way, fewer transmitting terminals can be used to complete the support of a larger spatial electric field and establish a higher intensity electric field environment.

[0068] like Figure 5 As shown, in some specific embodiments, the emitter electrode 2 may include a threaded rod 21, a fixing nut, a threaded pipe plug, and a plurality of electrode sheets 22, all of which are located in the insulating protection tube 1. The middle of the plurality of electrode sheets 22 is provided with a through hole 221 and is sleeved on the threaded rod 21 at intervals; the fixing nut is threadedly connected to one end of the threaded rod 21; and the threaded pipe plug is threadedly connected to the other end of the threaded rod 21. Figure 6 As shown, in some specific embodiments, the cross section of the electrode sheet 22 is a star-shaped structure. Since the charge values ​​of the multiple sharp ends of the electrode sheet on the periphery of the star-shaped structure are increased, a greater electric field strength can be generated under the same power; at the same time, the sharp ends of adjacent electrode sheets are spaced equally, and the electric field will form a superimposed enhanced electric field in the surrounding space.

[0069] like Figure 4 As shown, in some specific embodiments, a suspension column 5 may also be included, and the suspension column 5 is inserted and fixed at the other end of the multi-way wiring valve 3.Figure 7 As shown, in some specific embodiments, it may further include two plug connectors 6, two wires 7 and two gaskets 8. The two plug connectors 6 are respectively inserted and fixed at opposite ends of the multi-way wiring valve 3; both of the two wires 7 are located inside the multi-way wiring valve 3; both of the two gaskets 8 are located inside the multi-way wiring valve 3 and are respectively electrically connected to the two wires 7, and both of the two gaskets 8 are electrically connected to both ends of the emitting electrode 2. By using the plug connectors, wires and gaskets, it is convenient to electrically connect the electrode plates inside the insulating protection tube.

[0070] During specific implementation, the pulsed electric field generator or the full-spectrum electric field generator is correspondingly connected to one of the plug connectors 6 through a wire, and then connected to one wire 7 and one gasket 8 in sequence; then it accesses the next resonance emission terminal from the other gasket 8, the other wire 7, and the other plug connector 6.

[0071] In one embodiment, as Figure 8 shown, the bipolar ion membrane sequentially includes from the inside out: a hydrophobic layer 81, an antibacterial layer 82 and a hydrophilic layer 83. A plurality of micropores 84 with a diameter of 5 - 50 microns are uniformly arranged on the bipolar ion membrane. The hydrophobic layer 81 is a PTFE or dimethyl silicone oil layer with a thickness of 0.01 mm. The hydrophilic layer 83 is a hydrophilic polyurethane layer with a thickness of 0.01 mm. The hydrophilic polyurethane is purchased from Shenzhen Yitian Chemical Co., Ltd., model 6028. The antibacterial layer 82 is a silver-loaded nano-titanium dioxide layer with a thickness of 0.003 mm.

[0072] Among them, the hydrophobic layer exhibits the hydrophobic characteristic of not being wetted by water when in contact with water in the air, while the hydrophilic layer exhibits the hydrophilic property of being wetted by water when in contact with water in the air. Due to the hydrophobicity of the inner surface of the bipolar ion membrane, the inside of the fresh-keeping bag can accommodate high-humidity air without condensation, and the moisture inside the food ingredients will not continuously evaporate, and the moisture will not be lost during long-term storage, achieving freshness preservation.

[0073] Due to the hydrophilicity of the outer surface of the bipolar ion membrane, when the external environmental humidity is low, a water film can also be formed, which can block the penetration of macromolecules in the external air into the membrane to form pollution (such as the smell of other food ingredients or the musty smell in the air). And the internal organic gases can smoothly pass through and be released to the outside. The antibacterial layer has the effect of highly inhibiting bacteria, effectively delaying food spoilage and extending the freshness preservation period. And a plurality of micropores are uniformly arranged on the bipolar ion membrane, and gas molecules can pass through, and due to the action of surface tension, water molecules cannot pass through.

[0074] The nano-titanium dioxide silver layer makes the bidirectional ion membrane have stronger photoelectrocatalytic characteristics, which can assist in the decomposition of organic gases. The nano-titanium dioxide silver layer makes the bidirectional ion membrane have semiconductor characteristics, which can make the electric field evenly distributed, thereby improving the intensity load of the space electric field. Since living cells (such as fresh fruits and vegetables) release ripening hormones and accelerate cell decay, nano-titanium dioxide silver can quickly catalyze the decomposition of organic gases under the action of electric fields or spectra, thereby inhibiting bacterial respiration and extending the shelf life. Nano-titanium dioxide silver is doped in the insulating material, which has the characteristics of a semiconductor during use, improves the electron mobility, and can make the distribution of the space electric field more balanced. With the help of the electric field, it can eliminate the dead zone of the space electric field and expand the space range.

[0075] The stacking of goods has a great impact on the electric field of the space. When there are more goods in the space, the electric field will be redistributed, resulting in insufficient electric field in some spaces, which greatly shortens the shelf life of these goods and causes losses. After being packaged with a bidirectional ion membrane, the goods are divided into several units. The electric field distribution is more uniform by utilizing the electric field enhancement characteristics of the ion membrane.

[0076] The full-spectrum microenvironment fresh-keeping system provided by the present invention has the following application features:

[0077] (1) Freezing and thawing

[0078] Freezing is performed in a pulsed oscillating electrostatic field environment. Due to the physical characteristics of water, when it freezes at 0°C, the expansion of ice crystals will destroy the integrity of the cells, and this damage will also occur during the thawing process. However, under the blessing of the electric field environment, the freezing point is below -4°C, avoiding the expansion stage of frozen crystals, thereby maintaining the integrity of the cells and maintaining the taste and nutrition without loss.

[0079] (2) Fresh-keeping and refrigeration

[0080] a. Under a certain intensity of electric field environment, the temperature can be reduced by 1-2℃ compared with traditional refrigeration, thus extending the preservation time;

[0081] b. Under an electric field of a certain intensity, biological cells enter a dormant state, and their internal life activities weaken, thus extending the shelf life;

[0082] c. In the variable frequency resonant electric field environment, various biological cells can easily enter a deeper dormant state, thereby extending the preservation time;

[0083] d Bidirectional ion stretch membrane is based on ordinary breathable microporous membrane, with silver ions and dioxide peptides added to the material, which has the function of assisting in antibacterial and catalytic decomposition of organic gases such as ethylene, while enhancing the electric field strength, preventing water loss, reducing deterioration and prolonging freshness.

[0084] (3) Keep fresh at room temperature

[0085] Although the shelf life will be rapidly shortened when the temperature rises after leaving the warehouse, the cells will recover from a deep dormant state and under the influence of the electric field at room temperature, the shelf life can still be longer than traditional preservation methods, with clear effects on fruits, vegetables and meat.

[0086] The present invention can extend the shelf life of stored goods and improve food quality through the synergistic effect of physical electric field technology and bidirectional ion membrane, while reducing energy consumption and costs, without relying on chemical preservatives, avoiding health risks and chemical agent processing costs; it has a wide range of applicability, is compatible with freezing, refrigeration and room temperature environments, and can be applied to a variety of food types such as fruits and vegetables, meat, and aquatic products. In addition, the bidirectional ion membrane packaging unit is flexibly designed to adapt to different storage and transportation scenarios to ensure uniform distribution of the electric field. The present invention is a purely physical preservation method without chemical residues, and meets food safety standards. It has significant practicality and promotion value in the field of food preservation.
