Technical Data:Two types of Mash Filter: with or without overhung membranesDaily batch: 14 brews/day, Max.16 brews/ dayTurbidity values: 2-3EBCSolids content in the wort:1-2ml/lWort oxygen suction:0.1ppmResidual sugar after grains sparging:0.6o PYield rate:100%Plate form: 1.5x2m, 2.1x2.1m, 2.4x2.4mFully automatic controlMoisture content of discharged spent grain cake: 70%The Superiority of Mash Filter TechniqueApplying membrane plate filter technique, the filter pre-extrudes spent grain layer by membrane blowing after original wort filtration and discharges most of wort in the spent grain layer, which reduces spent grain washing time and water consumption. After sparging, spent grain layer will be pressed again by membrane blowing and most of water will be extruded from the spent grain layer, which reduces not only water consumption but also the water content in spent grains, and also makes the spent grain transferring more convenient, as well as improves the yield.Overall welded membrane, made of imported polypropylene material, prolongs its service life greatly which can be more than 8 years overcoming the shortcoming of short service life of rubber material and moreover it dramatically enhances the intensity of membrane plate.Fixation way of the single point overhung filter plate makes it faster to transport the filtration plates and replace the filter clothes, as well as to run the filter. Up to 25T charge per filter can basically satisfy 130m3 brewing capacity.Effective way of filter clothes automatic cleaning guarantees the cleaning effect and reduces the maintenance cost.Special central mash infeed technique, and forward & reverse grains washing technique guarantee the well-proportioned mash distribution, the completeness of the grains washing, and the yeild rate, which also extend the cleaning cycle of the filter clothes and reduce the water consumption.Double-sided filtration with filter clothes embedded in both chamber plate and membrane plate, will increase the filtration area and reduce the filtration time.With cavity (protection) design, membranes can be pressed when there is few filter cake left or even no filter cake left, also supported by chamber plate to avoid overextension or damage.Meanwhile Lehui can also supply the Non-membrane Mash Filter which has similar specification and technical configuration with the Membrane Mash Filter.Mash Filter or Lauter Tun? It depends on the overall concept and the structural environment in which the brewery operates. The following are the examples of some superiorities of the mash filter.Improve the production efficiency: satisfy more than 14 brews per day; can filter wort when it is under the high viscid condition. The filtration will not be influenced by the raw materials quality; It is suitable for high concentration wort production. Lower production cost: high rate of wort yield, which can reach above 100%; suits different auxiliary materials; can produce wort by using raw material without husk; and can brew by large proportion of the auxiliary material. Improve the products quality: little oxidation, the whole filtration and grains washing process are under closed condition; low turbidity of the wort and small trub material content.Remark: Lehui has adopted the technology of mash filter in several projects such as Pearl River (Zhanjiang) brewery with 20 mil. tons annual capacity and Pearl River (Shijiazhuang) brewery 10 mil. Tons annual capacity.
