The scope of the FrostWave project is to develop a novel freeze-dryer supported with the microwave-based heating system for the food waste limitation and energy-efficient food storage for new food value chains.
Currently, the advance freezing systems are required in order to guarantee long-term natural preservation and high quality of the stored food. Such systems are usually not easily accessible for small and medium food producers. Meanwhile, the food preservation and storage technology should be suitable and affordable for utilisation on the early stages of the food chain. Promising food preservation method that meets the aforementioned criterions is freeze-drying technology. In that method, the whole water content is removed from the processed food. In a result, the processed products do not require cooling during the transportation or storage. The nutrition value of these products is much higher compared to those frozen within most common techniques. The freeze-drying technology significantly improves the food safety and reduce food waste.
The novel microwave-assisted freeze-dryer developed within the FrostWave project will guarantee the high quality of the processed food and improved energy efficiency of the device. Therefore, the vacuum chamber and MW heating unit, as well as natural working fluid-based refrigeration system for the freeze-dryer will be carefully designed. Within such approach, the novel device will allow to significantly reduce power consumption and amount of the food waste comparing to the approach based on frozen food storage. Consequently, reduction of the greenhouse gases emission will impact the environmental aspects and social standards by an increase of resiliency of food storage in regions without access to a reliable power grid. Hence, the main objective of the FrostWave is to develop the state-of-the-art freeze-drying unit supported with microwave heating for new food value chains and food waste limitation.
