Increasing the efficiency of vacuum freeze drying to meet modern energy-saving and ecological requirements

This is the authors' abstract. We don't add key points for this paper.

The article is devoted to increasing the efficiency of using freeze-drying in the context of global problems of energy shortages, losses of products, and raw materials for their production, as well as the growing threat of a growing carbon footprint in the world. It is shown that this technology is associated with the use of complex and expensive equipment and with high specific energy costs. For this reason, its use should bring maximum economic and environmental benefits. A way to reduce the carbon footprint could be freeze-drying raw materials with expiring shelf life, and their use in other sectors of the food industry. It is proposed to sell the water after defrosting the condenser plates through retail chains. Areas for increasing the energy efficiency of this technology include maximum use of natural energy sources, rational drying modes that ensure high quality with energy-saving operating modes of refrigeration systems and pumps.
