   4. Save the money invested for steam generator and steam supply equipment (don't need condensed water recover system)
   5. Save the money invested for soft water treatment and wastewater treatment
   6. Save equipment maintenance cost
   7. Create a quite and comfortable operating environment; to fit in with GMP HACCP regulation
       
2. How to do it
   1. Save water consumption over 89% : DN series water spray autoclave only need 5 ~ 8 % cooling water of the autoclave chamber volume
      1. Traditional sterilizer cooling process wasted a lot of cooling water
         1. Steam sterilize autoclave cooling process: city water pumped into the autoclave chamber to cooling the high temperature product, at the same time , exhausted warm water, keeping the inlet and exhaust action , till the products be cooling to the set temperature, the water consumption volume near 3 ~ 4 times of the steam autoclave chamber volume.
         2. Full hot water immersion autoclave sterilization cooling process : city water pumped into the autoclave chamber to cooling the high temperature product, same cooling process was batch cooling , some one was continuous cooling process, but all need cold city water 3 ~ 4 times of the immersion autoclave chamber volume.
         3. Vertical autoclave sterilization cooling process : its same as the water immersion autoclave sterilizer cooling process, its need cold city water 3 ~ 4 times of the vertical autoclave chamber volume.
         4. Negative factors of city water cooling process:
            1. Bacterial Contamination again: package material was heating in high temperature and a long time (121°C / 15~50mins), the seal and package material should be weak, when pumped into the cold city water ( 25°C ) the bacterial in the city water " maybe" contaminated the products again.
            2. Waste a lot of city water, then pay money to treatment the wastewater.
            3. Waste the invested of water supply and water treatment equipment
      
      
      1. Asepsis cooling process : Best solution of sterilization cooling process
         1. Asepsis cooling process: The circulation water had been fully sterilized, change the flow direction , Its pass through the after cooler ( cooling water heat exchanger), then inject into the autoclave sterilization chamber to cooling the products, its clean and asepsis, no more bacterial contamination again, the sterilization process was very safe.
         2. Cooling water consumption was zero : sterilization cooling process
            1. Close cooling system, the circulation water pass through after cooler should be cooling, the cold water circulated as the sterilization circulation.
            2. The after cooler was cooling by the chiller (cooling tower ), the thermal was exhaust to the atmosphere
                
   2. High efficiency thermal translate function, steam 100% use up
      1. Change liquid water to drops by spray nozzle, we can got a huge thermal exchange area.
      100 times thermal conductivity efficiency; steam condensed to saturate water the thermal transfer conductivity was 5,000 ~ 10,000 Kcl/(hr)(m
      ²
      )(°C); carbon steel thermal transfer conductivity : 54 Kcl/(hr)(m
      ²
      )(°C) ,  5000/54=~100 times, its means the thermal transfer efficiency of directly thermal transfer of water and steam, should be 100 times better then the steel and steam thermal transfer efficiency.
      1. Water drops fully absorbed the thermal value of steam, the steam thermal 100% to use, its the best energy efficiency.
      2. Without any type of heating heat exchanger, save the cost of sterilize autoclave equipment
      3. Don't need hot water recover equipment and recover pipe system, save the money invested of equipment and save maintenance cost
          
   3. Don't need exhaust steamout of autoclave chamber, for the steam autoclave sterilization, during sterilization process, 30% steam should be exhaust for the temperature distribution
      1. Exhaust steam should be negative factors as:
         1. Loss a lot of steam energy
         2. Room temperature should be high ( usually with pipe exhaust to outdoor )
         3. Noise from high pressure steam exhaust out
         4. Vapor in the atmosphere condensed into dew, Its should increase the relative humidity, the room environment would be wet
      2. Solution : with saturate water spray sterilization process
         1. Steam was inject into autoclave chamber, direct heating the circulation water,  the steam thermal value 100% use up, energy loss is 0%, save a lot of energy
         2. No more noise pollution form high pressure steam exhausting noise
         3. No more condensed drops, room humidity was comfortable
             
   4. Ideal sterilization process: Fully isolation circulation process: During the sterilization process cycle, the thermal medium of water was restricted in a close system, Its was isolated system, before the products was pull out of the autoclave sterilization chamber, the bacterial don't have any change to contact with the products, Our water spray autoclave sterilization is a Ideal sterilization process
