DEVICE AND METHOD FOR MEASURING CURRENT DENSITY OF BREAD STARTER Russian patent published in 2025 - IPC A21C14/00 G01N9/00 

FIELD: food industry.

SUBSTANCE: invention relates to the bakery branch of the food industry and can be used in the technology of the process of making bread and bakery products. Device for measuring current density of bread starter includes a saw-tooth voltage generator connected to a microwave generator, a volume microwave resonator, a detector and a meter for resonant frequency of the resonator, as well as elements for coupling the resonator with the microwave generator and the detector. Container containing the bread starter passes through the microwave resonator along its axis, wherein the material of the pipeline walls is radiotransparent. Method of measuring current density of bread starter is characterized by the fact that dielectric permeability of bread starter is measured using said device. In order to measure the dielectric constant of the bread starter, the resonant frequency of the resonator calibrated at the stage of maturation of the bread starter of the volumetric microwave resonator, which is excited on the lowest type of oscillations – mode E₀₁₀, is measured. Based on the results of measuring the current resonance frequency of the microwave resonator, the current density of the bread starter p_bs is calculated by formula where A, B are calibration coefficients.

EFFECT: invention makes it possible to measure density of current bread starter, excluding the weighing procedure, as well as to simplify the process of bread preparation due to reduction of its labour intensity.
