[0017] The following further describes the refrigerator cabinet for storing meat of the present invention with reference to the drawings.

[0018] As Figure 1 , 2 shown in Figure 3, a refrigerator for storing pork includes a cabinet body 1. The cabinet body has a doorway, and a cabinet door 11 is installed at the doorway. The inside of the cabinet body has a cabinet cavity 12, and the cabinet cavity is a freezing space for meat. The refrigerator further includes a refrigerating component 31. The refrigerating component can be, for example, a refrigerating coil or a semiconductor refrigerating component. The refrigerating component is installed around the cabinet body to keep the inside of the cabinet cavity at a low temperature. Its characteristics are: there is also an acid removal chamber 4 for meat installed in the cabinet cavity. The acid removal chamber is surrounded by a refrigerating component, which is the acid removal chamber refrigerating component 32. The acid removal chamber refrigerating component makes the temperature inside the acid removal chamber reach 0-5°C. A low-frequency electromagnetic wave generator 41 is also installed on the side wall of the acid removal chamber. A humidifier 42 is also installed on the side wall of the acid removal chamber. A blowing pipe 43 and an exhaust pipe 44 are also installed on the side wall of the acid removal chamber.

[0019] The refrigerator of the present invention is arranged like this. Fresh meat, such as pork, beef, mutton, etc., can be first placed in the acid removal chamber. The electromagnetic wave generator installed in the acid removal chamber ensures the overflow of harmful substances in the cells. The acid removal chamber refrigerating component makes the temperature inside the meat acid removal chamber reach 0-5°C, ensuring the low-temperature state of the meat during the acid removal process. A humidifier 42 is also installed on the side wall of the acid removal chamber to ensure the appropriate humidity of the meat during the acid removal process. A blowing pipe 43 and an exhaust pipe 44 are also installed on the side wall of the acid removal chamber, which also ensures the flowing air of the meat during the acid removal process, so that harmful substances are discharged in time. After the meat acid removal is completed, the acid-removed meat can be manually transferred to the freezing space.

[0020] Preferably, the humidifier can make the humidity in the acid removal chamber reach an environment of 80-90%.

[0021] Preferably, the frequency of the low-frequency electromagnetic wave generator is 20-50 Hz.

[0022] Preferably, a vibration component 45 is also installed on the side of the acid removal chamber. The amplitude of the vibration component is 1-2 mm, and the vibration frequency of the vibration component is 5-10 Hz. The acid removal chamber is also connected to the cabinet cavity through a vibration damping component 46.

[0023] The refrigerator of the present invention is arranged like this, which can also ensure the better advantage of the acid removal effect of the meat during the acid removal process. Installing the vibration damping component ensures that the vibration acting on the meat inside the acid removal chamber is less transmitted to other parts of this refrigerator.

[0024] The vibration damping component can be, for example, a vibration damping pad, etc.

[0025] Furthermore, for the acid removal chamber refrigeration component connection control device 5, the control device forms a low temperature - high temperature - low temperature fluctuation state through the acid removal chamber refrigeration component. Both the low temperature and the high temperature are within the range of 0 - 5°C, and one fluctuation process takes 4 - 6 hours.

[0026] With such a setting in the present invention, the meat in the acid removal chamber can be in a low temperature state for a while and in a high temperature state for a while, having a better acid removal effect. The control device can use, but is not limited to, programmable (PLC) control.

[0027] Furthermore, the air blowing pipe is also installed in the acid removal chamber through the telescopic component 47. When the telescopic component extends, the air blowing pipe can be inserted into the middle of the meat in the acid removal chamber.

[0028] Preferably, the outer end of the air blowing pipe also has a tip for easy insertion into the meat.

[0029] With such a setting in the present invention, during the acid removal process, the air blowing pipe can continuously insert into the meat, and the outer end of the air blowing pipe is at different parts of the meat, so as to discharge as much acidic substance in the middle of the meat in the acid removal chamber as possible, achieving a better acid removal effect.

[0030] Furthermore, the acid removal chamber has an inlet above, and an acid removal chamber inlet door 48 is installed at the inlet. There is also an outlet below the acid removal chamber, and the outlet leads to the freezing space in the cabinet cavity. An acid removal chamber flap door 49 is installed at the outlet. The acid removal chamber inlet door and the acid removal chamber flap door are connected to an electric control switch, and the electric control switch is connected to the control device. The control device has a timing unit. When the acid removal chamber inlet door is opened to place meat into the acid removal chamber, timing starts when the acid removal chamber inlet door is closed. After a certain time (such as 20 - 30 hours), the control device opens the acid removal chamber flap door, and the meat placed in the acid removal chamber is released into the freezing space of the meat.

[0031] With such a setting in the present invention, after a certain time, the meat can be automatically transported (dropped into the refrigerator) after acid removal is completed. The temperature in the refrigerator is -3 - -10°C, achieving automation.

[0032] Furthermore, when the acid removal chamber inlet door and the acid removal chamber flap door are closed, the acid removal chamber is still an airtight chamber. The air blowing pipe 43 is connected to a gas supply source through a air pump, and the exhaust pipe is connected to an exhaust fan through a valve. The air pump or / and the exhaust fan or / and the valve are connected to the control device. The control device makes the acid removal chamber alternately form positive pressure and negative pressure by controlling the air pump or / and the exhaust fan or / and the valve.

[0033] For example, the valve on the exhaust pipe can be closed, and the air pump can be started to force air into the acid removal chamber, so that the acid removal chamber can form a high pressure (positive pressure) state; the air pump can also be closed, and the exhaust fan can be started to force the gas in the acid removal chamber to be removed, so that the acid removal chamber can form a negative pressure state;

[0034] The control device may be a program-controlled device.

[0035] The present invention is configured in this way, so that the meat in the deacidification chamber can be placed in a negative pressure state at one moment and in a positive pressure state at another moment, thereby achieving a better deacidification effect.

[0036] The meat storage method of the present invention is further described below in conjunction with embodiments.

[0037] Example 1

[0038] The method stores fresh meat. Before storage, there is a deacidification process. The fresh meat is placed in an environment of 0°C. During this process, the meat is placed in an electromagnetic oscillation environment. During this process, the meat is placed in an environment of 80% humidity. The whole deacidification process takes 20 hours to obtain the first deacidified meat.

[0039] Example 2

[0040] It stores fresh meat. Before storage, there is a deacidification process. The deacidification process is to store the fresh meat in an environment of 5°C. In this process, the meat is in an electromagnetic oscillation environment. In this process, the meat is in an environment with a humidity of 90%. The whole deacidification process is 30 hours to obtain the second deacidified meat.

[0041] The obtained first deacidified meat and second deacidified meat have the advantages of less harmful substances, less tough meat, less microorganisms and less purine.

[0042] Furthermore, during the deacidification process, the meat is subjected to a fluctuation state of low temperature-high temperature-low temperature, wherein the low temperature-high temperature are both within the range of 0-5°C, and one fluctuation process takes 4-6 hours.

[0043] Furthermore, during the acid removal process, the meat is placed under alternating positive and negative pressure conditions.

[0044] Furthermore, during the acid removal process, air is blown into the meat to remove as many harmful substances as possible from the meat.

[0045] The meat that has undergone the above treatment has the advantages of being fresher, having better quality and containing fewer harmful substances.

[0046] The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
