Abstract:

The article inquiries into the issue of automation of the rice wine fermentation process in the field of industry 4.0. Fermentation is the process of converting D-glucose into ethanol along with oxidation of reduced coenzymes (fermentation). This is known as ethanol fermentation, which takes place anaerobically in the presence of yeast. The fermentation is being improved by automation (sensors, etc.). The main aim is to develop an experimental automation environment in industry 4.0 for the process of rice wine fermentation. During the rice wine fermentation process, variety of measurable attributes are created which affect the quality of the resulting product. They can be monitored with the help of automation elements (pH, temperature, humidity etc.). In case of an experimental environment development, it is therefore important to select appropriately the sensory that can record the measurable attributes. At the same time, the sensory must be at a level of reliability that guarantee their sufficient use in the mentioned experimental environment for the rice wine fermentation. The result is that, if the right environment is chosen, the quality of the fermented wine will improve.

Abstract:

The sustainability factor stimulates industrial companies to be more active and precise in improving their performance in relation to energy efficiency and environmental indicators. One of the more widespread practises to introduce improvements in energy efficiency and environmental processes is through energy and environmental management systems. However until now, there is a lack of practical studies assessing the role of environmental management systems to the improvement of the wood fuel production sector. The paper describes an analysis of lessons learned based on combined management-response and indicator based analysis on the introduction of environmental management systems (in accordance with ISO ¹⁴00¹:²00⁴) in an industrial enterprise. The chosen subject of this research is a wood pellet production facility located in Latvia. The research can be applied as a guideline for entrepreneurs in wood fuel production industry that are planning to implement energy and environmental management systems.
