Effective use and cleaning methods of pure steam generators

Pure steam is prepared by distillation. The condensate must meet the requirements for water for injection. Pure steam is prepared from raw water. The raw water used has been treated and at least meets the requirements for drinking water. Many companies will use purified water or water for injection to prepare pure steam. Pure steam contains no volatile additives and is therefore not contaminated by amine or skin impurities, which is extremely important in preventing contamination of injectable products.

Pure steam generator has the following characteristics and uses:
1. To reduce the impurity content in steam, we generally start from two aspects: pure steam generator material and water supply. All parts in the equipment that can come into contact with steam and steam output pipes are made of stainless steel, and are equipped with a soft water processor to purify the steam. The generator feeds water to reduce the impurity content in the steam. This kind of equipment is mostly used in food processing, pharmaceutical and sterilization industries.

2. To improve the purity of steam, reduce the water content, and achieve the dry steam or ultra-dry steam required by people, exquisite process conditions are often required. Generally speaking, pure steam generators correspond to higher temperatures, pressures, and larger liner. This kind of equipment is mostly used for experimental research and medical support.

Pure steam generator is an important equipment for sterilization and related equipment sterilization in biopharmaceutical, medical, health and food industries. These industries are crucial to the development of mankind. Therefore, more and more companies pay attention to the cleaning and disinfection of pure steam generators. In order to ensure that the cleaning and disinfection of pure steam generators meet the requirements and ensure better operation of the equipment, Nobeth will explain to you the cleaning and disinfection methods of the equipment.

1. Cleaning of the outer surface of equipment and pipe fittings
Wipe the surface of the device with a damp cloth every day before turning it on.

2. Use chemical cleaning fluid to clean
Chemical cleaning solution should be used for cleaning once a month, using deionized water and pickling agent + neutralizing agent. The pickling agent should be 81-A type safe pickling agent with a concentration ratio of 5-10% and the temperature maintained at 60 degrees Celsius. The neutralizing agent should be sodium bicarbonate aqueous solution, with a concentration of 0.5%-1%, and the temperature should be maintained at about 80-100 degrees Celsius. Note: The pickling agent and neutralizing agent selected should ensure that they do not damage the steam generator pipe material. Operation method: close the thermal resistor valve, pump the pickling liquid into the machine from the raw water inlet, and discharge it from the steam outlet. Repeat the cycle several times according to the dirt condition of the steam generator to dissolve 1mm thick dirt for about 18 hours, and then use it after pickling. The neutralizing agent is repeatedly cleaned for 3-5 hours and then rinsed with deionized water for 3-5 hours. Check that the discharged water is neutral before the steam generator can be put into normal operation.

3. After starting according to the normal operation method, let it run normally, and then turn off the raw water to allow the steam to rush into the steam dish to preheat and be discharged through the steam pipe.
