Pure steam generator is one of the important equipment used in tank equipment, pipeline system and filter sterilization, and can also be used to drive the sterilizer. The quality of pure steam condensate prepared by Biocell pure steam generator meets the requirements for water for injection in the current USP, EP, JP and ChP, and also meets the relevant standards of EN285.

TYPES OF PURE STEAM GENERATION SYSTEM

Pure Steam Generator

Pure steam generator is a device that uses water for injection or purified water to produce pure steam. It is widely used for sterilization and disinfection of medical and health care, biopharmaceutical industry and food industry, as well as disinfection of related appliances, to effectively prevent re pollution of impurities such as heavy metals and pyrogens.

Clean Steam Generator

The clean steam generator is used to generate pure and clean steam without any harmful substances and impurities. It is used in the food, cosmetics and pharmaceutical industries, as well as in the sterilization and any direct steam heating processes with high requirements for steam quality.

PURE STEAM GENERATOR WORKING PRINCIPLE

Pure steam generator is composed of evaporator, preheater, buffer tank, condenser, electrical appliances, instruments and pipelines.

Its working principle is: qualified raw water enters the branch condenser after being pressurized by the raw water pump, and then enters the separator and evaporator. The liquid level is controlled by the liquid level switch. The industrial steam enters the evaporator to heat the raw water to the evaporation temperature and form a strong thermal cycle in the evaporation chamber and separation chamber. After the raw water evaporates, the steam with water droplets will enter the separator, and the water droplets in the separator will be separated from the steam under the action of gravity and incorporated into the raw water. In addition, the unique steam water separation device on the upper part of the separator will generate ultra pure steam on the upper part of the separator.

PURE STEAM GENERATION SYSTEM INTERACTIVE FLOW CHART

FEED WATER

Feedwater must be pumped into the generator, typically at 10 psig above the operating pressure. The flow is usually controlled by level.

INDUSTRIAL STEAM

Most pure steam generators use industrial steam heating, but for low capacity systems, electrical heating can be used.

The pressure of industrial steam must be higher than the required pure steam pressure, To provide a temperature difference for heat transfer. For economic reasons, the industrial steam pressure is usually at least 30 psi higher.

PURE STEAM

Sterilisation in pharmaceutical manufacturing is usually carried out at 121℃ (equivalent to 15 psig for saturated steam). Equipment and pipelines, where there is often no pressure control and achieving sterilization temperature is entirely dependent on the supply pressure of the pure steam.

DROPLET REMOVAL

The ability of a pure steam generator to remove contaminants depends on preventing droplets from being carried in the steam. Therefore, droplet removal is critical to the generator function.

MATERIALS OF CONSTRUCTION

The overcurrent part of most generators is made of AISI 316L stainless steel to avoid corrosion.

BLOWDOWN

The concentrated water after continuous evaporation is regularly discharged from the bottom of the generator, including the liquid drops (bacterial endotoxin and pyrogen) removed by steam water separation. Usually, timed blowdown is used, which can also be triggered by conductivity measurement. The discharge of concentrated water is about 10% to 15% of the feed water.
