Foods and beverages are best when they taste fresh, smell good and look appetizing. However, consumer demand is pushing for longer and longer shelf life. These conflicting objectives can be achieved with careful handling in an environment low in bacteria. Sanitary and aseptic pumps by NETZSCH can play a central role, since a progressing cavity pump is often a fundamental requirement in processing.
In addition to the increasing need for gentle, sanitary product handling, cleanability requirements of equipment are important. To be in accordance with CIP or SIP cleaning procedures, the pump must include the right features.
Positive-displacement pumps developed and produced by NETZSCH were designed for uncompromising hygiene and meet the most demanding of processing requirements. High-grade products can be handled in a safe and gentle manner. Our sanitary and aseptic pumps offer a wide range of application for your manufacturing processes.
Due to their sensitivity, wines are considered to be a difficult fluid to pump, while carbonated wines present completely different challenges: Each variety, for example, has a special carbon dioxide overpressure that must be observed. At the same time, the released CO2 increases the tendency of the beverage to foam, which impairs the quality of the goods. More...
Juices and other drinks generally cause few problems when it comes to a company's internal material logistics - thanks to their good flow characteristics, they are easy to convey and empty out. However, such straightforward handling also leads to poor practices in terms of hygiene, such as when juice is openly decanted so that contaminants can enter the system. More
In 1996 two friends with a passion for brewing premium beer opened the doors to the Brewing Company, a bar, restaurant and brewery in Downingtown, Pennsylvania. From a converted factory building where they brewed 1,725 barrels of beer in their first year. More
Statistics tell us that every German citizen eats around 9.5 kg of chocolate a year, in the form of bars, hollow figures, pralines and such like. There is a particularly steep rise in consumption at Easter and Christmas. Chocolate may be very popular, but it is extremely complicated to make. In particular, the temperature has to be precisely controlled at all times to achieve the later melt-in-your-mouth effect. More
Globally, there are around 285 million people who suffer from diabetes according to the estimates of the International Diabetes Federation (IDF) and this figure is predicted to be 438 million by 2030. More

Yoghurt is one of the exceptionally demanding conveyor media in the food sector. On the one hand, it is vital to avoid strong shear forces so as to protect the valuable bacteria cultures and prevent separation of the different phases. On the other hand, the product, like almost all dairy products, is critical in terms of hygiene, which means that all pump materials have to meet food safety requirements and comprehensive cleaning has to be carried out regularly.

In everyday practice in the foodstuff industry high demands on hygienic processing are required for the primarily sensitive products, simultaneously, there is the high pressure of competition and efficiency. More
Fish is not just one of the staple foods in all the world's coastal regions, its high-quality constituents mean it is globally becoming a significant component of a healthy diet. Most of the residues are disposed of or processed into cheap animal feed, but the skins do for instance contain valuable proteins. One of the main global suppliers of catfish deals with customers in around 40 countries. The company does not just export the fish meat, but also produces high-quality by-products from the fish parts which would otherwise be designated as worthless residues. A key product is a collagen powder. More
When it comes to conveying systems in the foodstuff industry a careful transportation of the medium is a frequent precondition. A big problem for economic conveying of foodstuff is the sensitivity of the majority of the raw materials. Pumps that develop pressure or heavy shearing forces on the medium, can result in the conveyed goods being impaired or even destroyed. This is particularly applicable to fruit and vegetables. More
When it comes to conveying systems in the foodstuff industry, the main focus is primarily on hygiene, cleanability and compatibility with food. When emptying containers using progressing cavity pumps for example, barrels can be drained to a residual quantity of less than one percent. And, thereby, they provide higher cleanliness and safety against contamination than, for example, open tilting devices. More
