Since the beginning of 2000, SIFA's research & development centre has been committed to the goal of performing brightening filtrations in high quality wines. A project was created based on the use of microfiltration with neutral material, such as Polypropylene and Teflon with large porosity, extensive filtering surfaces and low flow rates and pressures, all managed with fully regenerating daily washes by flushing high flow rates of water, in current and counter-current, assisted by techniques used to increase the contact surfaces. Thus was created the new Microfilter and Movifilter filtration system, which completely replaces the long natural decantations, the use of obsolete diatomaceous earth, filter sheets, lenticular filters and centrifuges. A system capable of filtering high-end wines, whites and reds, with an excellent cost-benefit ratio in terms of initial investment and cost per litre processed, ease of use and wide area of application.  A wide range of machines including manual, semi-automatic and automatic is present.  The accessories are used to customise the system according to the customer's requirements.

The DDWine series cross-flow filtration systems, with polymeric membranes, are dedicated to the oenological sector, for the filtration of musts, lees, still wines, sparkling and spumanti wines, with particular sensitivity to the organoleptic and qualitative aspects of wine. The engineering of these systems is highlighted in the construction details that allow filtering in the various production cycles of the winery, ensuring in a single step perfect brightening of the product and the maximum protection of its ecotypic characteristics. They can be used on musts before fermentation, in partially fermented musts, on wines at the end of fermentation, on clarified products, on products that need to be preserved for a long time, in the preparation of sparkling base wines, in the filtration after the second fermentation, and in those production phases that require the obtaining of a sparkling product whose microbial flora is controlled. Our wide range of systems is able to meet the needs of any type of company. Designed as monoblocks starting from 30 up to 360 m2 of filtering surface.

SIFA's membrane concentration systems are designed for use in the food and beverage industries. Their function consists of increasing the content of the extracts in fruit juices, grape musts, whey and syrups, when it is convenient to concentrate substances of high molecular weight, while maintaining maximum respect for the organoleptic characteristics of the product, such as the fragrance and aromas. The production yield in relation to the energy required is undoubtedly cheaper than heat exchange systems. These systems are built completely in stainless steel and are equipped with a self-supporting structure and are wheeled in order to facilitate their use; in particular, the parts in contact with the liquid to be treated are made of AISI 316 stainless steel. To regulate the working pressure, they are equipped with a particular “REM” valve designed to easily obtain the pressure necessary to separate the solvent. To ensure long work cycles and high hydraulic performance with reduced mechanical energy losses, they are fitted with a special three-cylinder pump suitable for the treatment of viscous products and able to withstand the cleaning cycles involved for the various membranes.

SIFA's flotation systems are used for the cleaning and clarification of grape juice musts to be used for fermentation or for sterilising filtrations. The parts in contact with the liquid are made of stainless steel and polymer suitable for use with food substances. The system is based on the ability to create micro-bubbles that bind to the flocs of organic substance making them light in such a way as to separate from the medium, reaching the surface of the liquid in a short space of time during the envisaged holding time in storage tanks. The addition of nitrogen or air gas for food use, the balancing of the circulator, the injection and regulation system of compressed gas (air or nitrogen), and the pump for the dosing of any flocculant allow high performance even in the presence of dirty products.
