Ohmic heating is used as a novel heating method with development potential, the dielectric property of food is utilized, an electric field is applied to two ends of a material, current is generated inside the material, electric energy is converted into heat energy, the temperature of the food is increased, and therefore the purpose of direct and uniform heating sterilization is achieved. Compared with other traditional heating methods: the heating device has the advantages of quick heating, uniform heating, accurate control of heating temperature, 95% of electric energy conversion rate, environmental friendliness, no phenomena of scaling, scorching and the like on a heating surface and the like. The induction heating is to generate current in the heated material by using an electromagnetic induction method, and the heating purpose is achieved by means of the energy of the eddy current. The basic components of an induction heating system include an induction coil, a high frequency ac power supply, and a workpiece. The coil is connected to a high frequency ac power supply which supplies an alternating current to the coil, the alternating current flowing through the coil generating an alternating magnetic field through the workpiece which causes the workpiece to generate eddy currents for heating.

The problem is aggravated in the flowing process of the fluid, the flow velocity of the fluid at the pipe wall is slow, the heat transfer time is long, the temperature is high, the flow velocity at the center of the pipeline is fast, the heat transfer time is short, and the temperature is low, so that the temperature difference between the fluid at the pipe wall and the fluid at the center of the pipeline is larger, and the fluid food at the pipe wall can be overheated, and the fluid food at the center of the pipeline can be insufficiently heated. Under the ohmic heating technology, although it is ensured that the whole section of fluid can be heated simultaneously, the existence of the flow characteristics of the fluid in the pipeline, the temperature difference between the fluid at the pipe wall and the fluid at the center of the pipeline still exists, and the electrode is easy to be corroded by electrolysis under the low-frequency power supply. In the case of a single induction heating technique, induction heating generates heat by generating eddy currents on the surface of the workpiece, and transfers heat to the fluid through the surface of the workpiece, which is performed by heat conduction, similarly to the heating method of the conventional heating technique. Under the independent action of the three technologies, the problem that the temperature of the fluid at the pipe wall and the center of the pipeline is greatly different cannot be avoided.
