Use areas and the development process of the vacuum dryer
Vacuum Dryer industry, in order to evaluate the performance standards of a class of vacuum dryer is probably only the three basic criteria! "All" refers to the materials into the vacuum dryer equipment, in the circumstances to ensure the same amount of materials out, the moisture content of materials are well-proportioned. Does not appear, this case half of the moisture content of half of the moisture content. "Dry" refers to the vacuum dryer the most basic features! Materials into the vacuum dryer equipment, there is a certain amount of wet water.
  Rotary drum dryer is a well received by high-temperature heating and chief transportation equipment, have a wide range of applications in food, chemical, metallurgy, building materials and other industries.
  Rotary drum dryer compared with other drying equipment, production capacity, continuous operation; simple structure, easy to operate; failure, low maintenance costs; wide range of applications, the fluid resistance is small, you can use it to dry granule-like materials for adhesion great material benefit; operating flexibility, and allow the flow of the product on the production have a greater range of fluctuation will not affect the quality of the product; cleaning easy.
  First use of mechanical solid-liquid separation equipment, such as filtration centrifuges, vacuum (or pressure) filters, sedimentation, filter and static thickening, etc., to separate the solids from the liquid.
  With the continuous progress and development of micro-computer technology and automatic control technology, many areas of the introduction of the computer to automatically detect and control technology, and computer automatic monitoring and control system requirements have become more sophisticated, flexible configuration software to be shipped students.
  First use of mechanical solid-liquid separation equipment, such as filtration centrifuges, vacuum (or pressure) filters, sedimentation, filter and static thickening, etc., to separate the solids from the liquid. A process to select the best type of mechanical separation equipment, vacuum dryer according to the solid nature of production and method of operation and other factors to decide.
  Vacuum Dryer is by removing the packaging container internal air to reach a predetermined degree of vacuum inside the container of water equipment, remove. Work when dry, the tank in a vacuum jacket through hot water (or steam, conducting oil) heating, with the tank low-speed rotation, the material in the tank continuously from top to bottom, inside and outside as a "diamond-shaped trajectory" movement and to absorb the evaporation of water The steam is continuously discharged through the vacuum line to achieve the purpose of drying. According to customer requirements in the dry mixture at the same time, built-in spray, filtering, grinding, and other devices to achieve its multi-function operation.
  The vacuum drying process is a complex, time-varying nonlinear industrial processes, drying control is to adjust and control the process parameters that affect the entire drying process.
  With the continuous progress and development of micro-computer technology and automatic control technology, many areas of the introduction of the computer to automatically detect and control technology, and computer automatic monitoring and control system requirements have become more sophisticated, flexible configuration software to be shipped students. Of MCGS (Monitor and Control Generated System, and general monitoring system) is a set of configuration software is used to quickly build and generate computer monitoring system, it can be based on Microsoft (various 32-bit Windows platform) running through the collection of field data processing animated displays, vacuum drying alarm processing, process control, real-time curve history curve and report output to a variety of ways to provide users with a program to solve practical engineering problems, take full advantage of Windows graphics capabilities, interface consistency, easy to learn easy-to-use features, than using a dedicated machine, the development of industrial control systems more versatile, has a wider range of applications in the field of automation.
  An important driving force to make our products the drying effect of changes in the evaporation temperature of the contained liquid, and vacuum drying temperature depends on the process pressure. The evaporation temperature lower process pressure drop can bring many benefits, especially for contact drying. Not necessary to design a minimum pressure and maximum allowable temperature operation ideal drying system, because it would require large and expensive peripherals. Systems are generally designed to be self-regulating pressure vessel. In other words, the condenser and the vacuum device is suitable to handle the higher pressure under the high steam flow, pressure is also reduced when the drying decline.

  Synthesis process in many chemical and pharmaceutical products (intermediate or final products), the solid particles suspended in a liquid, at a certain stage separated from the slurry. First use of mechanical solid-liquid separation equipment, such as filtration centrifuges, vacuum (or pressure) filters, sedimentation, filter and static thickening, etc., to separate the solids from the liquid. A process to select the best type of mechanical separation equipment, vacuum drying based on the solid nature of production and mode of operation and other factors to determine. But usually only by a mechanical solid-liquid separation step can not meet the requirements of product quality, because only rely on mechanical force can not remove all the liquid. The product discharged from the centrifuge or filter, depending on the products and equipment, humidity is generally in the range of 5% to 80% (by weight). Therefore, after the completion of the mechanical solid-liquid separation, the general need to heat solid-liquid separation step, the residues in solid liquid separation. This step is often referred to as "dry".
