There are many types of dryers, such as: freeze-drying machine, adsorption dryer, modular dryer, membrane dryer, dissolving dryer, etc. Here, I introduce you to the common three kinds of dryers, , Adsorption and combination.
   1. The principle of the freeze dryer is to cool the air to a saturated temperature by cooling, since the saturated air moisture content is 100% or less, so that we can, by various factors such as inertia, Gas and water separation, gas to the end of the use of water through the sewage outfall, so you can achieve the purpose of dry air.
  2. Adsorption dryer principle is: the design of two towers, are filled into the alumina or molecular sieve, their characteristics are rapid water absorption, easy to dehydration, that is, under high pressure water can use their own dry air after the pressure change The water from the silencer blowing out of the tower, which is why the adsorption dryer to design the reasons for the two towers, two towers continue to switch back and forth in order to ensure that the gas in the case of effective take off the process, so as to achieve effective Of dry air.
  3. Combination dryer: is the combination of the above two kinds of machines, because a particular request for a higher industry will choose, the best dry and dry dew point is 2-10 degrees, the dryer is about -40 degrees , If the combination can reach -70 degrees, because the cold and dry machine will be a lot of liquid water in advance to exclude, after the suction machine will be gaseous water adsorption to get more dry air, dryer there is a more interesting feature is The low temperature of the regeneration air is low and the temperature of the dehydration is high. It is beneficial to play the role better. Therefore, the cold air temperature after the first cold and dry machine is low, the adsorption is favorable, and then the regenerated dehydration gas is heated to 160 degrees Adsorbent dehydration, so the effect of dehydration better, because the typing slower so much to say, I hope you can gain.
