WebMICROWAVE-VACUUM DRYING PART I 123 Applying microwave energy to dry food materials seems to be an applicable approach for coping with certain drawbacks of conventional drying (Decareau and Peterson 1986). When microwave energy is applied to foods, heat is generated within the product. Therefore, the temperature of the product Web11 aug. 2009 · A comparative drying experiment between the hot-air and microwave-vacuum method of blue honeysuckle slice has been completed. In hot-air drying, the temperature was 50°C when the velocity of air stream was kept at 0.5 m/s. In microwave-vacuum puffing, the microwave power and vacuum pressure were set at 2.68kW and …

Webserial hot air and microwave dehydration are pasta drying and the production of dried onions (Metaxas et al., 1983) whereas only intermittently successful in the 1960s and 1970s was the finish drying of potato chips. The combination of microwave and vacuum drying also has a certain potential. Microwave assisted freeze drying is well studied, but no WebREV™ uses a combination of Vacuum & Microwave energy, which results in a rapid, gentle drying process. By controlling the pressure and microwave power density, one can effectively control both the temperature and the final moisture of the product. Adding microwave energy to the drying process allows for an efficient energy transfer where … prussia is not a country with an army
