ApplicationThe Carbonator is designed for continuous injection of carbon dioxide into beer and beer-based mixed drinks. A precisely defined and constant CO2 content is an essential quality feature for carbonated beverages.DescriptionFor CO2 supply the Carbonator has a specifically designed Vortex-Venturi injector that feeds carbon dioxide in a very large number of very fine bubbles directly into the product stream. Due to high pressure and turbulent flow, the CO2 dissolves completely and absolutely homogeneously in a very short time. At the end of the dissolving path a control valve is installed. This valve keeps the pressure in the system constant and above the saturation pressure. The flows and the CO2 content are permanently monitored and automatically adjusted in the process. Therefore, the system is equipped with high precision flow meters and a CARBOTEC sensor made…
ApplicationThe yeast pitching system YeastPitch doses yeast cells fully automatic and homogeneously into the wort stream.DescriptionThe yeast pitching unit is a fully automated system that measures and controls the addition of liquid yeast into the wort line with extreme precision. In the standard design the skid is equipped with accurate flow meters. Optionally, turbidity sensors or a live yeast cell monitor can be used. Differential turbidity measurement before and after yeast dosing ensures that the right amount of yeast is dosed into the wort. Variations in the basic turbidity of the wort are automatically compensated for. As an alternative to differential turbidity measurement, the dosed yeast can be controlled by in-line live cell measurement. A specifically designed injector then blends the yeast and the wort together. The yeast cells are…
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…
