Embodiment
[0034] The main parameters of this embodiment are: the average thickness of the side of the ham is 25 cm, the applied voltage of the high-voltage electrode is 5-50 kV, the pulse width is 2-10 μs, and the pulse voltage is 100-300 Hz. Taking the device and method applied to Jinhua dry-cured ham as an example, the implementation of the device and method is further elaborated:
[0035] Implementation steps: The fresh bone-in pork leg (thickness 25cm) after preliminary thickness classification and modification is transported to the pulse electric field treatment area by a grounded metal conveyor belt. During the process, the upper surface of the ham is in close contact with the surface of the high-voltage electrode and a peak A pulse with a voltage of 50kV, a pulse width of 10μs, and a frequency of 120Hz. The total processing time for bone-in pork legs was 10 s through the conveyor belt at a speed of 5 cm / s. After the ham has completely passed through the processing area, it enter...
