Abstract

The present invention relates to a reaction product viscosity detection method having a viscosity detection process including a rotation speed detection process and other processes. The rotation speed detection process is a process for detecting the rotation speed of an induction motor in which the power loss (PL) occurring when power (P) is supplied consists of a power loss (A) and a power loss (B) and includes: a step (?) in which the difference between the power (P) and the power loss (A) is assumed to be a first-order approximation value (PM1) of the mechanical output of the induction motor and a first-order approximation value of the rotation speed given by the equation N1 = NS(1 - S1) is obtained from the relationship between the output (PM1) of the induction motor and slip (S1) given by the equation PM1 = ?S1; a step (??) in which the power loss (B1) is obtained based on the first-order approximation value (N1); and a step (???) in which a second-order approximation value (PM2) is assumed to be given by the equation P - (A + B1) and a second-order approximation value given by the equation N2 = NS(1 - S2) is obtained from the relationship between the output (PM2) and slip (S2) given by the equation PM2 = ?S2.

Description

technical field [0001] The present invention relates to a method for detecting the viscosity of a reaction liquid using an induction motor as a power source, a viscosity detection device for the reaction liquid, a method for obtaining a reaction product, and a manufacturing device for obtaining the reaction product. Background technique [0002] The inventors of the present invention have proposed a reaction liquid viscosity detection device installed in a reactor in which the reaction liquid is stirred by rotating the stirring blades with an induction motor driven by an inverter (inverter) as a power source ( Patent Document 1). This detection device is characterized in that it has each unit of the following 1) to 5), and the input power (P I ), power loss (P L ), angular velocity (ω) as the basis, through T=(P I -P L ) / ω to obtain the rotational torque (T), and calculate the viscosity of the reaction liquid from the rotational torque.
