Description

technical field [0001] The invention relates to an intelligent high-voltage pulse generator. Background technique [0002] Food sterilization methods have been developed to this day, and there are many kinds. These methods can be roughly divided into two categories: one is heat treatment, and the other is non-heat treatment. Pasteurization is the most commonly used method in the food industry. There are various methods of heat conduction, such as high-pressure steam instant sterilization, low-temperature pasteurization, etc. However, heat treatment will inevitably have some side effects on the nutritional value, flavor and taste of food, especially for heat-sensitive or special-required foods, it is often difficult to achieve the desired effect, so non-heat treatment is attracting more and more attention. Non-heat treatment includes adding preservatives to inhibit microorganisms, centrifugation to remove microorganisms, radiation treatment to kill microorganisms, etc. No...
