Innovation, energy saving, environmental protection is the development direction of vacuum dryer
Vacuum dryer has many advantages: low oxygen content under low pressure when dry, to prevent drying material oxidation, can be dangerous goods dry flammable and explosive; at low temperature the water vaporization of material, easy to dry heat sensitive materials; recycling dry materials in the valuable and useful components can be prevented; the toxic and harmful substances in emissions of dry material, can become the environmental protection type "green" drying. Therefore, application of vacuum dryer equipment more widely.
  The main disadvantages of vacuum dryer is need a steam pumping vacuum system, making equipment, high investment cost, operation cost is high; the equipment production efficiency is low, output is little. In order to overcome these shortcomings, many scientific and technical workers, has made a lot of efforts. At the same time, because the vacuum dryer has many advantages, some products have to use the vacuum dryer equipment. Therefore, will be the future development of the vacuum dryer equipment.
  Innovation is the fundamental way out for the development of vacuum dryer
  The vacuum dryer slow development, there are 1 important reasons is mutual imitation, hovering around the same level of technology, lack of innovation. Imitation ability, speed, innovation concept, less input. The competition focus on the relationship, grab the market, price war. A better approach is in quality and after sale service, some Kung fu. But these are not the development of vacuum dryer a good way, must input of human, material and financial resources, to innovation.
  Energy saving is the key to the development of vacuum dryer
  Energy shortage has attracted the attention of the whole world, the traditional idea that the energy consumption of vacuum drier high, because it needs to add the vacuum pump. But not seen in the same kind of material, drying to the same moisture content, comparison of energy consumption of real. In fact, vacuum drying is dried in a closed space at low temperature, less energy waste. Even so, the energy-saving vacuum dryer is still the key to the development of. Compared with other types of drying equipment, key energy-saving vacuum dryer should be
  The discharge in the rational design, selection and use of vacuum system.
  Not many can steam pumping vacuum system, there are mainly two categories, one is able to direct pumping steam pump, main water jet pump, steam jet pump, water ring pumps and wet roots vacuum pump; the other is a water condensation method. Energy consumption of these two kinds of methods are relatively high, one kind of energy saving direction should be to improve the pump efficiency; energy after a class is designed as the structure of gas phase and solid phase transformation heat exchanger and the heat efficiency.
  Continuous vacuum dryer is to improve product yield, an important method of saving energy
  Compared with the continuous vacuum dryer and cycle type vacuum drier, less auxiliary time, saving time and improving production. At the same time he don't like cycle vacuum dryer, each producing a circular, equipment temperature change, repeated heating leads to energy waste in the equipment components. Therefore, energy saving.
  Combined vacuum dryer and other drying methods should be advocated mode of production
  Vacuum drying and other drying methods are combined to improve the production efficiency, reduce the cost of product. For example, vegetables, aquatic products and fruits by vacuum drying products, product quality can be assured, if the vacuum drying before after cleaning, blanching, centrifugal dewatering, and then cold drying to remove the surface water, and then into the vacuum dryer, can greatly improve production efficiency, reduce production cost. Spray combined with freeze drying is the combination of. This kind of similar
  Combination way, through the test, find many, certainly also must spend a certain amount of time, energy and money.
