A leading company in the food industry produces semi-finished and finished products from grain. In the production plant, they use a pressure reducer from Mankenberg GmbH to heat a honey tank.
Regardless of whether they are energy providers at the beginning of a busy day or only a snack in between meals. Cereal products have become vital for our everyday life. Bee honey still is an important ingredient for many of these sweet meals.
Maintain a constant temperature level
Raw materials and ingredients are of various consistencies. Often they expose the foodstuffs industry to great challenges. For example during the transport of grain, large amounts of dust are released.
Honey, that enhances the taste of popped grains or cereal bars, loses its flowability under cooler temperatures and transforms into a viscous mass. To prevent this from happening, the producer has to continuously heat the honey to a temperature level of approx. 30 to 40 °C.
Pressure reducer regulates the steam pressure
In the production plant of a cereal production company there is a tank of approx. 40 m³ filled with honey. It is constantly heated in order to keep the tank content capable of being pumped. In the heating circuit, a steam generator produces water steam with a pressure of 8 bar absolute.
In the downstream steam supply line, the pressure of the generated steam reduces to 4 bar absolute. This happens with the help of the pressure reducing valve Mankenberg DM 618Z. It flows through a ball valve that opens pneumatically as soon as the temperature falls below 40 °C. After that the steam flows into a heat exchanger, condenses there and dissipates the heat to the environment. The arising condensate is separated in a steam trap and flows back in the return line to the condensate collector. Then you can re-supply it to the steam generator.
Cast steel valve body
The self-acting pressure reducing valve reduces the steam pressure downstream of the valve to the suitable plant pressure of 4 bar absolute. The sturdy and low-maintenance control valve can withstand inlet pressures of up to 40 bar and features very favourable flow dynamics.
The valve body is out of cast steel and the medium-wetted internal parts are of corrosion-resistant stainless steel (1.4404 / SS316L). Therefore, this metallic-sealed control valve is ideally suited for this steam application.
