Microwave vacuum drying equipment is a new microwave energy application equipment which combines microwave energy technology with vacuum technology. It combines a series of advantages of microwave and vacuum drying, and overcomes the shortcomings of long cycle and low efficiency of conventional vacuum drying. Microwave vacuum dryer has the advantages of high drying output, good quality and low processing cost. Microwave vacuum drying equipment consists of microwave generator, vacuum drying chamber, material rotating disk, vacuum system and electronic control system. In industrial production, many articles can not be dried at high temperature. For example, some medicines, chemicals, nutritious food, ginseng, antler and other high-grade Chinese herbal medicines, in order to ensure product quality, the drying process must be carried out under the conditions of 100 C or room temperature. It is well known that the boiling point of water decreases with the decrease of pressure. For example, at one atmospheric pressure (101.3 kpa), the boiling point of water is 100 C, while at 0.073 atmospheric pressure (7.37 kpa), the boiling point of water is 40 C. Under vacuum conditions, heating the object can evaporate the moisture inside the object without temperature rise.
Conventional vacuum drying method has the characteristics of slow heat conduction speed, high efficiency and difficult temperature control, resulting in internal and external temperature difference between heated materials. Microwave heating is a kind of radiation heating, which is the direct action of microwave and material, so that it can be heated both inside and outside without convection or conduction to transfer heat, so it has fast heating, high drying efficiency and good drying quality. It provides a new and efficient drying equipment for food engineering, pharmaceutical engineering, biological engineering, chemical engineering, material engineering and deep processing of agricultural and sideline products.
uses microwave vacuum drying equipment to process raisin free raisins. The traditional technology is dried at 65 and 24 hours by hot air drying to 50 and 5 hours by microwave vacuum drying. The instant orange powder is processed. The product not only keeps its original color and fragrance, but its vitamin retention is much higher than that of spray drying. The efficiency of microwave vacuum drying equipment on dehydrated vegetables is four times that of conventional vacuum drying equipment. It can be seen that microwave vacuum dryer is a high-tech application with remarkable economic benefits and high popularization value.
