ApplicationThe vacuum deaeration system VeGaS removes oxygen from water, liquid food and dairy products. This improves the flavour stability and extends the product lifetime.DescriptionA specifically designed dispersion nozzle continuously sprays the liquid product as fine droplets into an evacuated vessel. The very large number of very small droplets maximizes the transfer surface and the contact time between the product and the vacuum. The large partial pressure difference of O2 forces the oxygen out of the liquid product into the vacuum. This fundamental scientific principle is described by Henry’s Law. The removed oxygen is transferred out of the vessel with a vacuum pump. To enhance the system performance, a strip gas like carbon dioxide or nitrogen can be added into the vessel. The O2content of the deaerated product is permanently monitored. Therefore,…
ApplicationPure steam is used for sterilization of tanks, pipeworks and filling machines. The pure steam generator PureSteam produces sterile, pyrogen-free steam that is ideally suited for SIP (Sterilization-in-Place). The system can also be designed for the production of clean steam for direct injection into the product.DescriptionFor pure steam generation the feed water enters a tubular heat exchanger with an expansion chamber above. In the tubular heat exchanger the pre-treated water is heated and steam is generated. The tubes of the heat exchanger are connected with the expansion chamber that serves as a separating column. For production of pyrogen-free steam the chamber contains a demistor. After entering the expansion chamber, the steam moves further upwards in the column. By gravity and due to the specific column design, unevaporated water droplets fall…
ApplicationThe Unipressure System is used in the beverage industry to accurately measure and control the pressure in one or more tanks. This is an essential requirement for maintaining consistent product quality.DescriptionAs compact, prefabricated assembly, the Unipressure System requires little space and is quick to install on site, with minimal field welds. It is fully automated and designed to suit each customer’s specific requirements. The system controls the supply of gases and CIP media into the tanks through the tank tops. For sterile applications a sterile gas filter is installed. Double seat valves prevent the intermixing of products and cleaning media. The Unipressure System can be combined with a Centec valve manifold or designed as an independent, compact assembly. Typically, the system is used with storage tanks, fermentation vessels, pressure tanks…
ApplicationCentec produce skid-mounted, mix-proof valve manifolds for a large range of applications. Typically, they are used for distribution and regulation of liquids such as water, product and CIP medium.DescriptionAs compact, prefabricated assemblies, valve blocks reduce space requirements, field welds and installation time on site. They are fully automated and designed to suit each customer’s specific requirements, e. g. with specific dimensions or adjustable feet. The product wetted materials and the surface roughness are selected according to the application. To achieve a high level of cleanliness in the pipework, orbital welding technology is typically used. Double seat valves prevent the intermixing of products and cleaning media. In addition to the design and supply of new valve blocks, Centec also modify existing valve manifolds. Such adaptions may be required due to the…
ApplicationCentec manufactures tanks for a large range of applications: CIP tanks, dosing tanks, pressure tanks for deaerated water, product buffer and storage tanks, as well as vessels for product preparation in various industries.DescriptionProfound experience in process technologies, highest production standards, carefully selected materials and extremely precise manufacturing, results in tanks and vessels of outstanding quality. Reliable pressure transmitters and load cells are used for accurate level control. Temperatures and pressures inside the tanks are controlled within narrow limits. A large range of options are available such as agitators, homogenizers, measurement instruments and sampling devices. For monitoring of concentrations, oxygen and carbon dioxide, high precision sensors made by Centec can be integrated. Centec have decades of experience in the development and manufacturing of own precision instruments. Single and double wall tank…
ApplicationWhere more stringent hygienic standards apply, sterilization-in-place (SIP) is done after CIP cleaning. SIP kills harmful microorganisms that may have survived CIP or in cases where Cleaning-in-Place is not performed.DescriptionCentec provide a large variety of SIP systems. SIP systems are designed by Centec in such a way that optimal sterilization results are ensured, with the lowest consumption of water, chemicals and energy. While one part of the plant is sterilized other areas can continue to produce product. For the production of pure steam, Centec offer pure steam generators. The steam temperature is above 121 °C. If required the pure steam generator can be enlarged by additional columns to build up a multi effect distillation system. This allows combined generation of pure water and pure steam at the same time.Sterilization concept…
ApplicationThe purpose of Cleaning-in-Place (CIP) is to remove product residues and microorganisms from all wetted surfaces inside tanks, pipework and filling machines. Centec provide CIP skids for cold and hot cleaning in brewery industry.DescriptionCleaning and sanitization must be performed periodically at appropriate intervals. A typical CIP cycle consists of various steps, e. g. pre-rinse with purified water, flushes with caustics and acid solutions, intermediate and final rinse with purified water. Chemicals and detergents are sometimes used to enhance cleaning performance. Depending on the system, after each cleaning step the cleaning media is either routed to drain (lost CIP) or back to the storage tank for later re-use (batch CIP). Temperatures, flow rates and times are adapted to the system dimensions and the cleaning tasks. Hot cleaning regimes use hot caustic…
ApplicationBy flash pasteurization harmful microorganisms in beer and beer-based mixed drinks are killed with the aim of improving microbiological stability and shelf life of the product. Flash pasteurization is a well-established and cost-effective process in brewery industry.DescriptionThe flash pasteurization system is designed to pasteurize the product gently without adversely affecting its colour, taste or digestibility. For optimum results, pasteurization time, temperature and pressure have to be individually adjusted. Optimum parameters depend on various factors, such as product, type of packaging and anticipated shelf life. Based on highly accurate process control, the unit guarantees constant pasteurization quality even at variable product flow directly in front of the filler. To increase the energy efficiency of the system, the product is warmed up to the pasteurization temperature in two steps. In the first…
ApplicationThe MultiMixer is used for the continuous mixing of several streams of liquid products, e. g. beer, syrup and flavours. Since the number of blending channels can be adapted to individual needs, the skid provides a high degree of flexibility for the production of different products (brands).DescriptionIn multi component mixing different liquid or powder products are blended. The components to be mixed can be supplied from large storage tanks via supply lines or from vessels located on the skid. Mass flows and concentrations are permanently measured in the process and adjusted by ratio controllers. Therefore, the system is equipped with high precision flow meters and in-line sensors made by Centec. Centec have decades of experience in the development and manufacturing of own precision instruments. Frequently, the MultiMixer is also used…
ApplicationNitrogenated beers have very small bubbles and very stable foam. The Nitrogenator is designed for continuous injection of nitrogen into beer and beer-based mixed drinks. The required N2 content is exactly reached in the final product.DescriptionFor product nitrogenation the Nitrogenator has a specifically designed Vortex-Venturi injector that feeds nitrogen in a very large number of very fine bubbles directly into the product stream. Due to high pressure and turbulent flow, the N2 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 system is equipped with high precision flow meters. Based on the measurement of the flows, the product steam and the nitrogen flow are…
