Too high a pressure can atomize the spray and lead to inefficient cleaning. Too low a supply pressure may result in the spray not hitting the surface with sufficient velocity for cleaning (if it hits at all). Sprayballs are designed and drilled to operate at specific flows and pressures. Sprayballs which have custom drilled holes should have a means of positively locating the sprayball to the correct orientation. Nozzles and manway openings must also be considered. The undersides of mixer blades are also a potential cleaning problem. Agitator shafts, baffles, and other common protrusions in the vessel can shadow certain areas in the vessel. The use of more than one spray device may be required to completely clean all the surfaces. The best type of action depends on the surfaces to be cleaned. There are 2 types of cleaning actions utilized, there is a cascading action of a large flow of chemicals running over the surfaces, and an impingement action caused by the direct spray. The holes may be designed to spray up only, spray down, spray in a 360 degree pattern, or they may be custom located to hit specific areas. The most common type of cleaning device is the sprayball, a hollow ball with an array of holes which sprays the interior of the vessel. There are many different cleaning cycles used in various industries, but most cleaning cycles involve a pre-rinse of clean water, a heated caustic wash cycle, a post rinse cycle, and some type of sanitizing cycle. There are numerous types of sprayballs and spray heads designed for the cleaning of the interior surfaces of vessels. Crevices, pockets, threads, and non-draining surfaces must be avoided. GEA is listed in the German MDAX and the STOXX® Europe 600 Index and is also among the companies comprising the DAX 50 ESG and MSCI Global Sustainability and the Dow Jones Sustainability Europe Indices.Vessels designed for sanitary service are almost always cleaned in place and/or sterilized in place by a combination of heat, and the circulation of chemicals over all of the surfaces to be cleaned. In doing so, GEA makes a key contribution toward a sustainable future, in line with the company’s purpose: "Engineering for a better world". They contribute significantly to the reduction of CO2 emissions, plastic usage, and food waste. GEA plants, processes, components, and services enhance the efficiency and sustainability of production processes across the globe. With more than 18,000 employees working across five divisions and 62 countries, the group generated revenues of more than EUR 5.1 billion in fiscal year 2022. The international technology group, founded in 1881, focuses on machinery and plants, as well as advanced process technology, components, and comprehensive services. GEA is one of the world's largest suppliers of systems and components to the food, beverage, and pharmaceutical industries. Safe production lines and safe connection points to the related process or filling machines along with an efficient and time-saving procedure are of vital importance. GEA has extensive experience with sterile processes for almost every task. This is most important in the case of filters that have been used for a sterile filtration. Having ended the SIP process, all sensitive components have to be checked for their proper functionality and integrity. This is done by means of blowing out the system with sterile air and, in case of process vessels, the cooling system via the jacket is activated. After sterilisation, a system in contact with steam has to be cooled down. In the pharmaceutical industry, sterilizing in place is done in almost all cases by using saturated steam at a pressure of 1 bar. Sterile production requires sterile plants. It is imperative that all equipment coming into contact with the product must be subjected to a documented temperature-controlled sterilisation procedure with hot media. Prerequisite for the manufacture of sterile liquid pharmaceutical products is that loop and machine systems are kept sterile. The cleaning steps are specifically configured under consideration of the kind of product to be manufactured.įrom mobile or stationary cleaning systems up to CIP satellites fed with conditioned cleaning media from a central unit – the variety of special solutions for your process plant is vast. GEA verifies whether one or several CIP cleaning vessels are required to achieve the maximum cleaning effect for each plant. GEA provides high-performance cleaning and sterilisation concepts that are individually adapted to the client's very specific requirements.
