Built on the company's own hardware and software, the system acquires and controls the key thermal parameters of brewing through field instruments, an in-house control system and a cloud platform. Heat engineering, automatic control and big-data analysis mine distillation practice and heat and mass transfer mechanisms, clarifying how key parameters affect base-liquor yield and quality and optimising the process, raising output by 1-8% and cutting steam use by 3-10%. Work covers steam-to-grain transfer, unsteady flow of non-azeotropic mixtures in the pot cooler and data-driven optimisation.
