FIELD: food industry. SUBSTANCE: method involves measuring $$$, comparison of $$$ to corresponding critical region $$$ and $$$. If condition $$$ holds, $$$ is processed further. Then method involves calculation of $$$, comparison of $$$ to $$$ (current sampling size). If condition $$$ holds, request is generated in order to stop measurement of $$$ while $$$ and $$$ are calculated. Then method involves calculation of $$$ and statistic estimate $$$, comparison of $$$ to $$$. If condition $$$ holds, "Stop" signal is generated. Then method involves calculation of $$$, comparison $$$. If condition $$$ holds, "positive correction" and "negative correction" signals are generated for $$$ and $$$ respectively. Then measurement of $$$ is blocked while "positive correction" and "negative correction" signals are active. Then current sampling size $$$ is decreased by one and new sampling size is assigned to current value. Then new current sampling size is compared to $$$. If condition $$$ holds, sampling size for next control loop is assigned to value of $$$. If condition $$$ holds, sampling size for next control loop is assigned to $$$. If condition $$$ holds, sampling size $$$ is increased by one and new value of sampling size is assigned to current value. EFFECT: increased functional capabilities. 2 dwg, 1 tbl
