The invention discloses a rotary pulse electric field generator sterilization device, which comprises a base, a motor, a motor shaft, a blade-type upper electrode, a lower electrode, a lower electrode wire, an upper electrode carbon brush and a liquid pipeline. The base has a lower electrode fixed on the upper bottom surface; the motor is arranged on one of the fixed plates, the output shaft of the motor passes through the two fixed plates respectively, and a blade-type upper electrode is fixed in the middle of the motor output shaft; the blade-type upper electrode Between the lower electrode and the lower electrode, there is a liquid pipeline; the motor shaft, the lower electrode, and the liquid pipeline are in the same vertical plane; the end of the motor output shaft is provided with an upper electrode carbon brush; one side of the lower electrode has an electrode wire drawn out. Between the lower electrode wire and the carbon brush on the motor shaft, a DC voltage U is applied; the blade-type upper electrode rotates with the rotation of the electrode shaft. The invention has simple structure, reliable operation, accurate waveform and extremely low cost, which solves the problem of Continuous flow liquid in-line sterilization technology.
Description
technical field [0001] The invention belongs to the technical field of food machinery, and relates to a sterilization device, in particular to a pulse electric field sterilization device which utilizes rotating blades to generate a pulse electric field to quickly sterilize food. Background technique [0002] High-voltage pulsed electric field sterilization technology is a new type of non-thermal sterilization technology that is the latest development and the most active in the world. The principle of high-voltage pulsed electric field sterilization is to place food between two electrodes, and apply a pulsed high-voltage power supply to the two electrodes to generate an instantaneous high-voltage pulsed electric field between the two electrodes, which acts on the food and destroys the bacteria inside the food. The cell wall promotes the death of bacteria, thereby achieving a sterilizing effect. High-voltage pulsed electric field sterilization has a short time, no temperature...
