Аннотация

The calculation of the process of defrosting food in a microwave field is based on the problem of determining the density of internal sources of heat arising in a dielectric material when it interacts with an electromagnetic field. The article substantiates a simplified physical model of the interaction of an electromagnetic field with a homogeneous dielectric material of arbitrary shape, placed in the volume of a microwave resonator chamber. Equations are analytically obtained that allow calculating the density of internal heat sources during microwave defrosting of food products of arbitrary shape, which take into account the power of the microwave generator, the volume, surface area of the material and the depth of penetration of the electromagnetic field into the dielectric. An experimental check of the obtained equations was carried out, which showed the accuracy of calculations of internal sources of heat acceptable for practical purposes.
