[0002] The basic principle of ohmic heating is to use low-frequency alternating current (50 - 60 Hz) in cooperation with special inert electrodes to provide current, and utilize the dielectric properties of food itself. When the current passes through, electrical energy is converted into heat energy inside the food material, causing the food temperature to rise, so as to achieve the purpose of direct and uniform heating and sterilization.

In the embodiments of the present invention, functional units with the same reference numerals have the same and similar structures and functions.

[0037] Referring to Figures 1 - 5 , the present invention provides a water bath ohmic heating device, including:

[0038] A housing 1, inside which there is a heating cavity 2. A raw material carrier rod 3 is arranged corresponding to the middle of the heating cavity 2. Between the two sides where the heating cavity 2 is connected to the housing 1, there is a motor 4 and a transmission device 5 connected to the motor 4. At both ends of the heating cavity 2, there are telescopic electrode plates 6 respectively, and both ends of the telescopic electrode plates 6 are connected to the transmission device 5;

[0039] A spice storage cavity 7 is opened on one side of the housing 1 close to the heating cavity 2. At the bottom of the spice storage cavity 7, there is a mechanical pump 8. The middle of the heating cavity 2 is provided with an injection probe 9 in a ring shape. The injection probe 9 is connected to the spice storage cavity 7 through the mechanical pump 8. At the bottom of the heating housing 1, there is an ultrasonic emitter 10 corresponding to the raw material carrier rod 3. Near both ends of the telescopic electrode plates 6 in the middle of the heating cavity 2, there are elastic telescopic plates 11 respectively. At the bottom of the elastic telescopic plates 11, there are magnetic attraction springs 12. On the surface of the elastic telescopic plates 11 and the bottom of the telescopic electrode plates 6, there are protruding teeth 13 that are correspondingly engaged;

[0040] On the front of the housing 1, there is a control panel 14. The control panel 14 is electrically connected to the motor 4, the mechanical pump 8, the ultrasonic emitter 10, and the magnetic attraction spring 12 respectively. On either side of the housing 1, there are a power socket 15, an external water inlet 16, and an external water outlet 17. Between the two elastic telescopic plates 11 of the heating cavity 2, there are also an internal water inlet 18 and an internal water outlet 19. The external water inlet 16 is communicated with the internal water inlet 18, and the external water outlet 17 is communicated with the internal water outlet 19.

[0041] Referring to Figure 1, in this embodiment, the housing 1 is usually made of high-strength metal with an insulating coating, such as Q460 steel, etc. The housing 1 is provided with a heating cavity 2, and an observation window communicating with the heating cavity 2 can also be provided. The observation window can be made of PC material; the raw material carrier rod 3 is symmetrically engraved with scales on both sides with the center of the rod as the origin. The purpose is to ensure that the meat block is always located in the center of the heating cavity 2 during heating; the spice storage cavity 7 is used to store the spice liquid. The operator can pour the spices and seasonings into the spice storage in proportion before heating; the mechanical pump 8 is arranged at the bottom of the spice storage cavity 7 and is used to extract the spice liquid according to the heating program set by the control panel 14 through the mechanical pump 8 and inject it into the meat block through the injection probe 9; the telescopic electrode plate 6 is driven by the motor 4 and the transmission device 5 to move, and heat is generated inside the meat block after contacting the meat block to achieve heating; the ultrasonic emitter 10 is used to drive the raw material carrier rod 3 to perform ultrasonic vibration, which can promote the uniform mixing of the spice liquid in the meat block.

[0042] During use, the user can first mix the spices and seasonings in proportion in the spice storage cavity 7, pass the raw material carrier rod 3 through the meat block, and place it at the position corresponding to the ultrasonic emitter 10 at the bottom of the heating cavity 2. A central recess matching the raw material carrier rod 3 can be provided in the middle of the heating cavity 2. By starting the mechanical pump 8 through the control panel 14, the spice liquid can be injected into the meat block. Secondly, by starting the ultrasonic emitter 10 through the control panel 14, the uniform mixing of the spice liquid in the meat block can be promoted. Then, by controlling the motor 4 to drive the transmission device 5, the telescopic electrode plate 6 connected to the transmission device 5 is made to contact the meat block. Finally, by opening the external water inlet and the internal water inlet 18, the heating cavity 2 is filled with liquid, and the telescopic electrode plate 6 is started to achieve heating. Among them, when the telescopic electrode plate 6 moves, the magnetic suction spring 12 at the lower end of the elastic telescopic plate 11 is controlled by the control panel 14 to open the magnetic suction, so that the spring compresses and drives the elastic telescopic plate 11 to press down. When the telescopic electrode plate 6 stops contacting the meat block, it is defaulted to reach the corresponding position, and the magnetic suction spring 12 at the bottom is disconnected. The spring rebounds and drives the elastic telescopic plate 11 to press up, so that the corresponding protruding teeth 13 are wedged downward to form a sealed space to prevent liquid leakage during heating. This solution innovatively combines water bath and ohmic heating, and it is found that through the heat transfer of the water bath medium, the current in the meat block can be more evenly distributed, effectively avoiding the situation that some areas of the meat block are overheated in the traditional ohmic heating, that is, ensuring the quality of the meat block while achieving rapid heating.

[0043] In another embodiment, the telescopic electrode plate 6 includes:

[0044] a conductive thin plate 601 and an elastic conductive probe 602. Both ends of the conductive thin plate 601 are connected to the transmission device 5, and the elastic conductive probes 602 are distributed at one end of the conductive thin plate 601.

[0045] See Figure 6 , where the left is the internal contact plate of the conductive thin plate 601, and the right is the elastic conductive probe 602. One end of the elastic conductive probe 602 is connected to a spring. After the telescopic electrode plate 6 contacts the surface of the meat block, under the action of pressure, the corresponding elastic conductive probe 602 will retract a certain distance. After retraction, the shaded parts of the left and right in the figure fit together to form a current path, so that the elastic conductive probe 602 will be activated. When the device works, it mainly conducts electricity through the activated probes, while the unactivated probes are not charged, reducing the loss of current in water.

[0046] In another embodiment, the conductive thin plate 601 includes:

[0047] A current sensor or a voltage sensor is provided at one end thereof away from the elastic conductive probe 602, and the current sensor or the voltage sensor is respectively connected to the elastic conductive probe 602 and the control panel 14.

[0048] By setting the current sensor or the voltage sensor, during operation, the current sensor or the voltage sensor will analyze the distribution of the current inside the meat block according to the working current of each probe, and then flexibly adjust the voltage of each probe to ensure uniform heating of the meat block; on the other hand, when injecting the liquid material into the meat block, a small voltage can be applied through the current sensor or the voltage sensor, and the amount of the injected liquid material can be judged by the change of the conductivity of the meat block.

[0049] In another embodiment, the spice storage cavity 7 includes:

[0050] A spice storage cover 701 and a spice filter 702. The spice filter 702 is provided inside the spice storage cavity 7, and the spice storage cover 701 is covered on the top of the spice storage cavity 7.

[0051] See Figure 4 , by setting the spice filter 702, large particle spices are prevented from entering the mechanical pump 8 and causing blockage, and by setting the spice storage cover 701, the spice liquid is prevented from boiling over.

[0052] In another embodiment, the spice storage cavity 7 includes:

[0053] A heating rod 703 and a temperature sensor. The heating rod 703 is provided inside the spice storage cavity 7, the temperature sensor is provided at the bottom of the spice storage cavity 7, and both the heating rod 703 and the temperature sensor are electrically connected to the control panel 14.

[0054] See Figure 4 , by setting the heating rod 703, a heating program can be set through the control panel 14 to boil the spices, better extract the flavor of the spices, and monitor the heating temperature through the temperature sensor.

[0055] In another embodiment, the heating cavity 2 further includes:

[0056] A temperature probe 20, which is disposed around the middle of the heating cavity 2, and the temperature probe 20 is electrically connected to the control panel 14.

[0057] See Figure 1 , by setting the temperature probe 20, the central temperature of the meat block is detected in real time, so as to judge the end moment of heating.

[0058] In another embodiment,

[0059] The motor 4 includes:

[0060] See Figure 3 , the motor 4 adopts a stepping motor 4 to accurately control the stepping distance of the telescopic electrode plate 6.

[0061] This solution innovatively combines water bath and ohmic heating, and it is found that through the heat transfer of the water bath medium, the current in the meat block can be more evenly distributed, effectively avoiding the situation that some areas of the meat block are overheated in the case of traditional ohmic heating, that is, while ensuring the quality of the meat block, rapid heating is achieved. At the same time, in this device, the current distribution in the meat block is real-time fed back through the telescopic current electrode plate, and then the voltage of different regions is adjusted to ensure the uniformity of the current distribution inside the material; the ultrasonic emitter 10 can make the injected brine evenly distributed, so that the conductivity of each part inside the raw material is basically the same. The combination of these devices and heating principles ensures that the heating of the meat block is carried out from the outside to the inside, effectively preventing the occurrence of overheating points, avoiding uneven heating of the meat block, and thus ensuring the quality of the meat block.
