Filtered steam is required whenever steam comes in direct contact with food product or product contact surfaces.
It is also necessary to protect sterile filter integrity when using steam to sterilise filter elements. Filtered steam is recommended for the protection of precision modulating system components like pressure reducing valves, and to maintain efficiency of any heat transfer equipment.
TFI is offering replacement elements equivalent to Parker, Domnick Hunter, Sartorious, Millipore, Pall make filter elements.
In many applications steam comes in contact with the product itself. For example, direct injection of steam into large vats of processed foods is one method used to cook those foods. In other cases, steam is used to clean or sterilise surfaces, tools and containers used in processing and packaging of various products such as pharmaceuticals. In all cases, steam is being generated and distributed in piping systems, and these often end in small orifices or nozzles that can be easily fouled by contaminants in the steam.
Filtration of steam is essential to avoid product contamination and equipment downtime. Particulate contaminants found in steam can include rust, scale, dirt and sediments carried over from the water source.
APPLICATION
There are several terms used for steam. Process steam is used in process applications as a source of energy for process heating, pressure control and mechanical drives. Culinary steam can be direct injected during food processing. Culinary steam needs to meet 3-A Culinary Standards for the dairy industry. Process steam does not generally come in contact with the final product whereas culinary steam can, and often does, come in direct contact with the final product

Quality Orientation & Assurance
- All components are manufacturing from FDA approved material and listed for use in food contact as per Code of Federal Regulation (CFR -21)
- All products are inspected and released for dispatch after clearance from quality team
- All Element Manufacturing in 100% welded Construction and Fabricated without use of adhesives, Additional binders and glue.
- All Filter Elements are assembled, fabricated & welded packed according to ISO -9001.
- REGENERATION & CLEANING PROCEDURE
- Steam flow direction is out – to – in, the Sintered SS 316L Powder filter cartridge can be cleaned by Pressurised filtered compressed air, hot water, Steam at 2 – 2.5 Kg/cm2 pressure in reverse direction By applying Shock Wave from in – to – Out direction.
- The element can be also be cleaned by sonication in filtered water (open end must be closed) before dipping in water or cleaning solvent.
- After drying the element it can be reinstalled in the filter housing.
- Normally these filters are cleaned every week to avoid microbial growth on element surface.
- Sometimes dilute nitric acid 0.05% in filtered water is also used if any sticky mass is found on the element surface.
