Application of heat pumps in rapeseed oil production
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 3
Abstract
The production of rapeseed oil requires a lot of energy. Before being pressed, seeds are conditioned, i.e. heated up to the process temperature for the whole mass. Then, as a result of pressing the extracted oil has a higher temperature compared to the ambient temperature. The objective of the study was to assess the application of heat pumps to reduce the energy consumption of the vegetable oil production process. The article analyses the results of the industrial experiment in which a heat pump was employed to cool down oil and heat up rapeseeds before pressing. As part of B+R project No INNOTECH-K2/IN2/5/181835/NCBR/13, a prototype system was constructed with a capacity of 1.5 Mg of oil per hour. The research shows that the return on investment in the heat pump is maximum 2 months. Profit from heating seeds with heat obtained from oil cooling is about PLN 760,000 per annum in the analysed case.
