FIELD: electrical engineering.
SUBSTANCE: fryer (100) generates electromagnetic waves between a pair of opposite located plate antennas (102) to control water, which is an ingredient in products, namely the water activity of an object. A DC electric field of +100 V is applied as an offset electric field on a side of a water phase relatively to an oil phase in an AC electric field to irradiate products with electromagnetic waves at a frequency of 50 kHz.
EFFECT: improvement of the condition of products by increasing the inter-surface polarization between the water phase and the oil phase, reducing the inter-surface tension between the water phase and the oil phase by approximately 60% and binding water as a structure based on granular chains, thereby reducing water activity.
