Automated system of scientific studies of the technological process of wood drying

Abstract

The purpose of the article is to create an automated system of the technological process of wood drying that allows to research the physical processes, which take place in the drying chamber. The study employs a combined method of timber drying, which integrates an oscillating mode and natural circulation including the short-term cyclic opening of the outlet valve of the drying chamber with the periodic start of the forced circulation. The algorithm of the combined mode of timber drying is developed. A functional diagram of the automated system of scientific studies of the technological process of wood drying is proposed. A scheme of the ordered automation of the scientific studies of the technological process of wood drying is implemented. It allows both to control the process of wood drying and study the physical processes occurring in the drying chamber. An automated control stage of the specialized developments of the technological process of wood drying is based on the use of modern information-control devices, such as a programmed logical controller, microprocessor regulators and an industrial frequency converter.
