Cognac, brandy, cognac drinks

Home - Application - Food Industry (Beverage Industry) - Cognac, brandy, cognac drinks



Main technological tasks


Polishing filtration before bottling


Stabilization of the beverage (removal of excess amounts of metals Ca, K, Fe, Cu, etc.) by means of cation exchange filters


Improving the taste of the beverage


For polishing the filtration of cognac beverages, we propose to use a two-stage filtration scheme before bottling on the basis of cartridge filter elements.

The combination of "prefilter - finish filter" increases the reliability of the process, ensures maximum performance, high resource and economy of the entire system.

"Technofilter" offers several variants of combinations of microfilters from high-tech materials for cognacs of various classes.



The filter materials used help preserve all the organoleptic properties of the beverage.

The choice of the system should be carried out depending on the positioning of the drink





based on high-performance corrugated depth filters made of polypropylene  EPVg.P and microglass EPVS differs in low cost, increased resource without regeneration, high degree of retention of microparticles 0,9 microns and more. Filter elements are characterized by excellent wettability, inertness to alcohol-containing liquids, operate at a low differential pressure, provide good transparency and shine.



- on the basis of a highly efficient fiberglass corrugated deep prefilterEPVC) and a high-performance polyether sulfone membrane  with a 0.45 (0.65) μm (99.9%) retention efficiency of microparticles. The surface mechanism of particle confinement, inherent in membrane filtering elements, completely excludes the breakthrough of delayed particles in the filtrate (medium migration). Highly selective membrane filters give cognac drinks a special shine and nobility of color, contribute to the disclosure of the exquisite bouquet and the appearance of additional tones, significantly increase the spill resistance.

Stabilization of cognac drinks


To stabilize cognac drinks by removing excessive amounts of metals (CA, K, Fe, Cu, etc.), which lead to the formation of opacities and reduce the level of spillage, cartridge-based sorption-filtering elements of EPSP.T have been developed on the basis of cation-exchange resins.



At the heart of the filter element is a special cation-exchange resin. The material is characterized by high capacity, increased radiation, thermal and chemical resistance. Sorbent is insoluble in water and solutions of hydrochloric and nitric acids, it can be used in aqueous-organic media, including alcohols and ethers, and also in the presence of strong oxidants and reducing agents.


The EFSP.T filter element is a "minicolumn" with backfilling of the cation exchange resin between the inner and outer polypropylene casings and the longitudinal movement of the liquid. Elements are sealed at the ends of polypropylene melt, produced in height 250, 500, 750, 1000 mm, adapted to any type of filter holder. The recommended filtration rate is 20-40 l / h per element of 250 mm height, the service life of envy from the initial metal concentration and pH of the medium.


All filter elements of  "Technofilter" LLC are produced in accordance with the certified quality management system in accordance with ISO 9001: 2000.


For the stabilization of cognacs and cognac drinks, there are produced installations of the type USF with a set of cation-exchange columns - filtering elements of EPSP.T.
