ApplicationThe pre-isomerization system EASYOMER allows the economic use of hop products (natural hops, pellets, extract) due to a significantly increased yield of bitter substances. The compact unit can easily be integrated into an existing brew house.DescriptionEASYOMER optimizes the yield of bitter acids from hops. A new, scientifically proven heat treatment technique with hop specific parameters (temperature, pressure, pH, concentration, time) supports the solubility of iso-alpha acids. They remain dissolved to a particular high degree up to the finished beer. Since the pre-isomerization stage is separate from the brewing process (wort boiling), this highly efficient method complies with the German Purity Law “Reinheitsgebot” and has no negative impact on the aroma profile of the beer. By using existing process equipment, CIP systems and dosing pumps for the addition of hop bitters,…
ApplicationDissolved oxygen has adverse impact on flavour stability and shelf life. The deaerations system DeGaS-Hot removes O2 from water that is used for the production of beer and beer-based mixed drinks. For deaeration, the water is heated and disinfected at the same time.DescriptionFor treatment in the column deaeration system, the water is first heated to 72 °C or more in an integrated, regenerative heat exchanger. Heating reduces the oxygen solubility and simultaneously disinfects the water. The hot water is then dispersed at the top of the column. The column contains densely packed, thin stainless steel sheets arranged in such way that the water takes multiple paths as it flows down through the column. This maximizes the transfer surface and the contact time between the water and the strip gas (CO2 or N2).…
ApplicationDissolved oxygen has adverse impact on flavour stability and shelf life. The deaeration system DeGaS-Cold removes O2 from water that is used for the production of beer and beer-based mixed drinks. Deaeration is performed at ambient temperature.DescriptionFor treatment in the column deaeration system, water is dispersed at the top of the column. The column contains densely packed, thin stainless steel sheets arranged in such way that the water takes multiple paths as it flows down through the column. This maximizes the transfer surface and the contact time between the water and the strip gas (CO2 or N2). The strip gas is fed into the bottom of the column and flows upwards inside it in counter current to the water. The large partial pressure difference of O2forces the oxygen out of the water…
ApplicationDissolved oxygen has adverse impact on flavour stability and shelf life. The deaeration system DGS removes O2 from water that is used for the production of beer and beer-based mixed drinks. Deaeration is done at ambient temperature. The system is compact and easily expandable.DescriptionBased on the use of highly effective membrane modules, extraordinarily low values of residual oxygen are achieved. Each module contains thousands of hydrophobic, gas permeable hollow fibre membranes resulting in a large surface. This large internal surface of the modules maximizes the transfer area and the contact time between water and gas. While the strip gas (CO2 or N2) is applied on the inside of the hollow fibres, the water flows in counter current between them on the outside. The high partial pressure difference of O2 forces the oxygen out…
Application The reverse osmosis system REVOTEC produces demineralized water that is perfectly suited for manufacturing of beer and beer-based mixed drinks. Considering the quality of the raw water, the unit is designed individually for each specific application. Description Reverse osmosis (RO) is the reversal of natural osmosis. If a semipermeable membrane is placed between pure water and water with dissolved ions (salts) osmosis will come into play. The pores of the membrane only allow the passage of H2O, but not of salts, suspended solids, bacteria and larger molecules. Osmotic pressure due to a concentration difference on both sides of the membrane causes the pure water to pass through the membrane to dilute the solution on the impure side. This will continue until osmotic equilibrium (the same concentration on both sides)…
ApplicationThe ion exchange system IONTEC softens water used for beer and beer-based mixed drinks or for steam generation. Water hardness causes scale deposits in piping and process systems.DescriptionFor ion exchange there are ion exchange resins in the unit. These resins are insoluble granular polymers appropriate for the specific application. In their molecular structure they contain loosely held positive cations or negative anions. These ions exchange with the ions in the treated water as it passes through the unit.For softening of water a cation resin containing Na+ is applied. The calcium and magnesium ions which form hardness in water, creating scale deposits, are exchanged for the sodium ions of the resin. The resin binds more strongly with Ca2+ and Mg2+ than with Na+. When most of the ions in the resin have been replaced…
Raw water quality depends greatly on its source. Based on the raw water quality and the specifications for the purified water, Centec select the most appropriate technologies for each client. Usually, multi-stage regimes are necessary for water purification. For water pre-treatment, sand and multi media filters are used to remove suspended material (e. g. silt, clay, organic matter). Such material in water can reduce the effectiveness of downstream components such as ion exchange resins and reverse osmosis membranes. Soluble iron and manganese are found in water that contains no dissolved oxygen. They cause a metallic taste and form deposits in piping systems. The Centec De-Ironizer is designed for iron and manganese removal. If harmful bacteria and microbes are suspected, the water is disinfected by UV, ozone or free chlorine. Activated…
