The Hyghspin 70 twin screw pumps for the brewing and beverage industry from Jung Process Systems are ideal for handling delicate and mechanically sensitive yeast cultures.
Although centrifugal pumps are predominantly used in breweries today, there are several technological operations in the beer production process, including the transport of yeast, that require a special approach to both sterility and limiting mechanical impact on the pumped product. The brewing technology, perfected by German and Czech brewers, has many subtleties. In order for users to be able to buy a carpet, a soft sofa and spend their evenings sitting in front of the TV with a mug of ice-cold beer, technologists have to do a lot of work.
For the transport of yeast from the propagators to the fermentation tanks, Jung Process Systems offers twin screw pumps Hyghspin 70 in a wide range of sizes. The wide versatility of the 811 series, their high performance and the optimised internal geometry for non-contact cleaning have already been praised by brewers. At a temperature of 90°C, the pumps are capable of pumping yeast with a capacity of 11 m³/h, with an inlet and outlet pressure drop of up to 10.5 bar. In the non-contact washing mode, the pump operates with a capacity of 24 m³/h. The pressure drop reaches 2 bar.
Due to the low shear coefficient and the axial feeding pattern, the transport of the yeast has no effect on its consistency. The process is safe over a wide viscosity range, which is particularly important as the viscosity of brewer's yeast varies over a very wide range. The high degree of safety is guaranteed by the proven design of the pump and the correct selection of the optimum screw pitch, so that even at high flow rates, the pump working parts are unable to damage the structure of the yeast cells. In addition, the pump can be cleaned on site. For this reason, Hyghspin pumps are ideal for pumping delicate, pulsation-sensitive media that require a completely sterile environment for processing.
Jung Process Systems is a renowned manufacturer of high-quality stainless steel screw pumps for the food, biopharmaceutical, cosmetic and beverage industries.
