| Summary |
|
| Pure steam generator is one of important equipment using for tank , pipeline (SIP), filter and sterilized cabinet.Ultra-pure pyrogen-free pure steam generator produced byWatertown, according to WFI requirements of U.S Pharmacopoeia , EuropePharmacopoeia, Japan Pharmacopoeia and China Pharmacopoeia. The design andmanufacture submit to specification of pressure vessel , can be used to technics product line of food , pharmaceutical and biological gene engineering etc. |

Advantages |
- • Material : The contact parts with feed water , pure steam and WFI are 316L .
- • Electro-polish : To assure the quality of WFI and increase the life of equipment ,stainless steel surface treated by polishing .
- • Double tube sheets design:The design for external pre-heater ,condenser and I effect evaporator are double tube sheets , comply with requirements of cGMP, can?,prevent the possibility of low sanitation level media polluting system .
- • All heat surfaces is having jackets and outside is crossed by 304 stainless steel .
- • On the equipment , no removed parts , operate quietly and safely .
- • Controlled by PLC, standard procedure.
- • Integerated documents validation and service system .
- • Operation and maintenance easily .
- • Control system : to reach the different customer`s requirements , using PLC control technology . From the determine and distribution of pure steam quality to higher control , such as each media continuous regulation , storage system linkage , classification password control and evaporation quantity etc, we can check carefully .
- • Whole machine performance plant test : in the plant of whole machine test , according to decided procedure , test for the whole machine .

Working principle of PSG-S series pure steam generator : |
| Working flow chart of PSG-S pure steam generator as following : Through feed water pump , feed warer enters into the tube side of evaporator (they are connected ), level is cotnrolled by the level sensor and PLC . Industrial steam goes into the shell side of evaporator , heats for feed water to evaporation temperature in the tube side , feed water changes to steam , during the process of low speed and height of evaporator , the steam through the action of gravity , separated from the drop , then comes back to feed water and pre-evaporate , steam turns into pure steam , gets through a special clean mesh into the top of evaporator , then through output pipeline enters each distribution system and used point . |
Through the regulation of industrial steam , puressure of pure steam is setted according to processing technique , keeps it stable at the value setted by user . During the evaporation process of feed water , control the supply of feed water through level , keep it in nnormal level .For the concentrate , can drain intermittently . |

Working princinple of PSG-G series pure steam generator : |
| Working flow chart of PSG-G pure steam generator as following : Feed water is heating by plant steam in I effect evaporator , then enter into posterior II effect pre-heater , pre-heated by plant steam ; In the top of evaporator , after water separator , enters evaporation tube uniformly distributed , becomes film type stream in the evaporation tube ; Because very thin, so after evaporation , can become rebirth steam very quickly , the feed water which are un-evaporated drain out of machine .The rebirth steam , ascends in the evaporator spirally , outputs from pure steam outlet as pure steam after steam and water seperator . In the evaporator , pyrogen of plant steam absorbed by feed water condensates industrial steam condensate heating for pre-heater , pre-heat feed water discharges from outlet of pre-heater un-condensate . A little pure steam collected by sampler , change into distilled water after heating with cooling water ; check the quality according to the in-line test of conductivity . |
| After three times separation , feed water turns into rebirth steam which are clean .The first time evaporation , feed water enter evaporator , then flow , at the same time evaporates ;The evaporated feed water in the lower extreme of evaporator back turns , in the action of gravity , foreign matters separate in the under-part , this is the second separation time ; For the third time , the rebirth steam (evaporated feed water ) ascends in the evaporator spirally , separates in the middle and top special separator . |
| A portion of air in feed water can not condense , called uncondensable air , according to the automatica control degree , they can exhaust by device in the top of evaporator . |
 |
- feed water inlet
- distilled water outlet
- pure steam sampling orifice
- steam condensate outlet
- concentrate discharge
- industrial steam inlet
- pure steam outlet
- safety valve exhaust

Difference between S type and G type pure steam generator |
| Separator mode : S type pure steam generator using mesh type separation mode , but G type using spiral plate type speration mode . |
| Product specification mode range : when large , S type is better , see product type list . |
| Pyrogen using for pre-heater : S type no pre-heater , but G type has . |
| Evaporation principle : S type is external circulatory evaporation , G type is film falling evaporation . |
