The development and application of Wine filteration

Beer filter Diatomaceous earth filter. It is filtered using diatomaceous earth as a filter aid for beer filtration, the filter body to support pre-coated with diatomaceous earth filter layer is formed, and the feed as a whole, while adding a filter aid side filters have a filter capacity, low price, low running costs, can be automated, does not affect beer flavor traits and other advantages for today’s mainstream filtered brewery machinery and the necessary filter. Diatomaceous earth filter and the support structure due to the different sub-filter There are many types of application development are: Diatomaceous earth plate and frame filter. Some ultra-low carbon stainless steel, rust corrosion resistance, filtration speed, high-quality wine, liquor less losses, less carbon dioxide losses, before filtering the wine quality requirements low, easy to operate. Filter use only cardboard frame with diatomaceous earth as a filter medium or by intercepting sifter, depth effect and adsorption achieve filtering effect. Candle filter is a new filter. Take candle filter tube surface is coated with a pre-filter (diatomaceous earth) and increased pressure within the filter the way, it has a higher separation accuracy, isolated from beer yeast, colloidal precipitate to produce crystal clear beer. The latest candle type diatomaceous earth filter, developed by the KHS production, the gap between its member only 30μm (gap than the usual small parts of diatomaceous earth filter about twice). Diatomite pre-coat the filter does not need to burn melting aid products, with medium to aid a pre-coated with shortening precoat aid, reduce the amount of additives, easy to wash, saving washing water, use filters a long time and so on. Discharge centrifugal disc filter. There are I-Net, a good filtration properties and clarification filtration flow, pressure filtration closed, isolated from the air, no pollution, solid-phase distribution after filtration, sediment control and automatic cleaning filter. Diatomaceous earth filter aid can absorb large amounts of protein and other colloidal particles, beer clarification. The filter also small footprint, large filter area, compact structure and so on. The depth of the film separator type filter holder. Provided after diatomaceous earth filter used for collecting supplementary from diatomaceous earth filter aid and take down except yeast. It is mainly the role of mechanical sieve, sieve structure utilizing the direct removal of sediment adsorption and filtering does not affect beer flavor, aroma and quality, can fully remove solid and stable quality of beer, moderate operating costs, has been applied brewery . Cross-flow separator filter. Before the liquid is filtered on the inside of the tubular membrane processes for the circulation of high flow rates obtained liquid filtrate flows along the vertical direction. There are long flowing liquid through the filtration membrane surface. Use of membranes has polyethersulfone, ceramics, and polypropylene. Multi-layer sheet filter. Cellulose, diatomite, perlite, sintered glass and other materials by adhesive bonding into a thick layer of sediments 25mm molding these materials, filtration capacity of 15h1 / m2h, with sodium hydroxide and hydrochloric acid regeneration process , filtered beer clarification translucent. Vibrating membrane filter. It is a European application disc filter, the vibration in the horizontal direction, the filtered liquid may be given a high tear stress, can achieve high filtration efficiency and a high concentration of fluid at a small rate through a flow rate of the ring, can be used recycling yeast and beer ingredients in the residual stream. Shuangliu candle filter (abbreviated TFS). Germany Steineker developed, can control the entire process of beer filtration, the filtrate was adjusted flow rate, that is two shares of local and non-filter filtration accurate flow regulation, clearly determined Filter area, and a regulated flow into the filter area, filter sheet through the pipeline system is concentrated, and the filtrate is discharged directly, uniform flow, to improve the filtration efficiency 10%. Filter rod used may also significantly improve the speed of reverse flow, the use of dense and uniform Celite plate, and the mixture is greatly reduced, but also greatly reduce water consumption diatom excluded, there are extraordinary biological safety and high level of filtration. Liquid bag filter. Liquid bag filter is a closed filtration system, using pressure filtration. The entire bag filter includes a filter vessel, filter bag and a support network of three parts, the liquid to be filtered from the support network of the top of the filter bags inflow, so keep the entire filter surface to be evenly distributed throughout the filtering medium can also flow distribution surface uniform, not have a negative effect of turbulence, filtered liquid out bags, the solids trapped in the bag. Mostly made of high quality stainless steel filter container, the support mesh made of high strength stainless steel, polypropylene filter bag material. Cutting fluid bag filter can be used to fine filter brewery beer, draft beer sterile filtration, recycling beer filtration, replace diatomaceous earth filter to flow filtration system, filtered brewing water, sterile water preparation and fermentation tanks, yeast culture tank, cold wort saccharification ventilation air sterilization filter. Universal liquid bag filter, efficient and economic characteristics has been gradually applied to filtered beer, water and cleaning fluid like a brewery. Membrane filter. Membrane filtration is to reform the traditional filtration process that reform broth through diatomaceous earth and then filtered through cardboard crude fine filter, fine filter to replace the cardboard, the use of filter membrane technology to replace the original with a beer and a high temperature pasteurization UHT, beer can at room temperature in the remaining yeast and separating and removing contaminating bacteria for the production of fresh beer, low running costs, energy saving, draft beer while maintaining the original flavor of the beer, and the beer output more pure taste, nutrition, non-destructive. The universal application of international microporous membrane filter mostly 2-3 line filter in front of the filter with the filter element with large aperture depth filter (PP filter, etc.), the terminal membrane filter 1μm may be ultra-fine polypropylene fiber filter layer, 0.22μm or 0.45μm pore size filter membrane composite using acid polyvinylidene fluoride membrane, polysulfone and the like. As a result of the two layers of different pore size membrane filter made of a composite, the outer layer of larger colloidal particles can be filtered and yeast, to alleviate the burden of post-layer film, thereby improving the quality and quantity of filtered beer. Membrane filter material is generally stainless steel. Production of fresh draft beer membrane filtration application prospects. NORIT has developed a new beer filtration membrane filtration system, its modular structure can be continuous filtration of different types of beer, and a comprehensive, highly competitive. Wine filtration device Tubular membrane ultrafiltration device. In this film wine at a temperature of 0.3Mpa, 40 ℃ ultrafiltration, the average liquid permeable flux of up to 75kg / m2h, more than 98% of the total number of bacteria to remove the insoluble solids removed completely, crude protein removal rate is also high, minimal impact on alcohol, nutrients can be retained more than 86%. Ultrafiltration machine instead of the traditional thermal sterilization (fried wine), which uses external pressure membrane turbidity removal sterilization to give full bodied, mellow wine of fresh. Inflatable membrane filter press. Mainly from the rack, filter press plates, the hydraulic system has three major components. Distinct undercurrent with two flow. The machine uses hydraulic lock, press and other inflatable membrane structure in the production of rice wine can play a dual effect filtration and pressing, and good sealing, filter cloth (polyester) is not easily damaged, high production efficiency.
