Problems solved by technology

However, it is only suitable for the treatment of pumpable liquid materials, and cannot be applied to solid materials; it lacks a temperature control device, and cannot perform magnetic field treatment at a specified temperature; under semi-continuous conveying conditions, the material is in a static state in the sterilization treatment room. The lack of cutting effect with the magnetic induction line, the magnetic treatment effect is weak; the original intention of the equipment design is limited to material sterilization, etc., these factors limit the promotion of the equipment
Therefore, if it is necessary to conduct in-depth relevant research in the fields of food, biology, etc., the above-mentioned equipment cannot meet the requirements without any or a small amount of modification to the original system.

Embodiment 3

[0060] In the study of Antrodia camphorata liquid fermentation, the fermentation conditions were controlled at 27°C and the shaker speed was 150r / min. Calculated from the time of inoculation, the total fermentation days were 7 days. The magnetic field treatment was carried out at 48h after inoculation, and the magnetic field treatment was carried out again at the same time every day thereafter until the fermentation ended. The magnetic field treatment conditions are as follows: the treatment time is 2 hours per day, the magnetic field strength is 60Gs, and the material carrier speed is 0.5r / min. Every day after the magnetic treatment, the sample was quickly returned to the shaker for continuous cultivation. The biomass of Antrodia camphorata mycelium measured after the fermentation was 6.097g / L, which was 6.29% higher than that of the control group without magnetic field treatment.

Description

technical field [0001] The invention belongs to the field of food processing equipment research, and in particular relates to a rotating magnetic field processing device and a method for intensifying fermentation thereof. Background technique [0002] In recent years, biomagnetic technology, as a new edge technology, has been widely used in industrial and agricultural production, as well as food, biology and other fields. By adjusting parameters such as magnetic field strength and treatment time, magnetic fields can promote biological growth. Under the action of a magnetic field, factors such as microbial activity, enzyme production, and intracellular and extracellular material transfer efficiency can change significantly. Different from the ultrasonic field, the magnetic field can directly radiate the treatment object, does not need liquid as a transfer medium, and can be applied to solid-state fermentation. [0003] In order to meet the above-mentioned applications, magn...
