[0001] The invention relates to the field of fermentation equipment, and in particular to a fermentation equipment using an enhanced high-voltage electrostatic field. Background Art

[0002] High-voltage electrostatic field refers to a steady-state electric field that does not change with time. It has two forms: non-uniform and uniform. Because of its significant electromagnetic biological effects, it has attracted widespread attention in recent years and has become one of the most widely used non-thermal processing methods. It has been applied to varying degrees in the fields of aging, food freezing, thawing, drying, sterilization, breeding, and preservation.

[0003] In recent years, with the further development of biotechnology, the electrical effects and electrical properties of cells have become increasingly clear. With the development of modern microbial technology and its application in many fields, finding technologies and methods that can accelerate the production, reproduction and metabolic rate of engineered bacteria has become an important topic of concern to relevant scientific and technological workers.

[0004] Most microorganisms contain certain electrolyte components, and appropriate high-voltage electrostatic field treatment will inevitably affect their life activities. It has been proven that external electrostatic field can change the transmembrane potential of biological cell membranes, and the potential difference generated can trigger the activation of enzymes, promote the synthesis of ATP, increase the permeability of cells inside and outside, and affect physiological metabolism; direct current field can accelerate the reproduction of cells, and after protoplasts are treated with electrostatic field, cell division is stimulated to a certain extent; the effect of high-voltage electrostatic field on catalase was studied, and it was found that the electric field strength of 2×10 4 -3×10 4 At 400 V / m, catalase is activated to varying degrees, with activity increasing by up to 32%.

[0008] A more preferred option is that the two sides of the metal electrode are respectively connected to the two ultra-high dielectric ceramic layers, the edge of the metal electrode and the two ultra-high dielectric ceramic layers form an annular groove, and the insulating silicone layer is filled in the annular groove.

[0009] More preferably, the dielectric constant of the ultra-high dielectric ceramic layer is 3000-20000.

[0010] A more preferred option is that the two strengthening electrode plates face each other as concave surfaces that gradually become thicker in the middle toward the surrounding areas.
