An information processing device includes: an information acquiring part configured to acquire plating process information including operational motion information including target paddle motion information indicating an agitating motion of a target paddle corresponding to a paddle to be processed, plating solution motion information indicating a motion of supplying a plating solution to a plating tank, and carrier machine motion information indicating a motion of carrying a substrate and operational-motion paddle vibration information indicating vibration characteristics of the target paddle when an operational motion is performed, the motions being operational motions performed by a substrate plating device; and an information generating part configured to generate agitating-motion paddle vibration information in response to the plating process information by inputting the plating process information acquired by the information acquiring part to a learning model which has learned a correlation between the plating process information and the agitating-motion paddle vibration information using machine learning.

An apparatus for controlling viscosity of a slurry includes a mixing module mixing raw materials for a secondary battery, and a processor performing machine learning for prediction of viscosity of the slurry, predicting viscosity of the slurry in real time during a mixing process through machine learning, and adjusting conditions of the mixing process performed by the mixing module such that a predictive viscosity of the slurry meets a target viscosity.

An apparatus for mixing two liquids is provided. The apparatus includes a static mixer, and a first and second feed module for feeding the two liquids to the mixer. The feed modules include pressurizable chambers for accommodating flexible containers which hold the liquids to be mixed. The liquids are forced through the static mixer when the chambers including the flexible containers are pressurized. Pressurization is achieved by pressurized gas stored in pressure reservoir chambers that are connectable to the chambers holding the flexible containers. Related methods of mixing two liquids are also provided.

A system for blending fluids includes a hopper that contains an additive, a first flow path extending from the hopper and operable to receive the additive from the hopper and convey the additive along a length of the first flow path, a second flow path in fluid communication with the first flow path to receive the additive from the first flow path, a mixing unit in fluid communication with the second flow path to receive the additive from the second flow path, a monitoring device arranged within the second flow path and operable to capture information based on a flow of the additive within the second flow path, and a controller electronically coupled to the monitoring device and operable to process the captured information and output the information to a console screen.
