GEA configures both stainless steel and fibreglass-reinforced plastic tank systems for liquid salt dosing, with capacities of up to 800 liters. All GEA systems have been developed to meet the highest hygienic requirements, and promise robust and reliable operation.
Our thermoregulated system for salt dosage is constructed around a cylindrical stainless steel tank with capacity of about 800 liters, in which the salt solution is prepared. The cold salt solution is then passed from the tank by centrifugal pump to the heating station, which comprises a heat exchanger with titanium plates. Heated saline solution is then piped to the stretching machines.
The desired temperature of salt solution can be easily set by the operator. The actual temperature is monitored by a feeler unit in the delivery pipe. This temperature data is then sent to the modulating valve, which automatically adjusts the flow of steam. Dosage of the solution at the correct temperature is adjusted by the operator at a valve in the delivery line.
GEA also offers a two-tank system for liquid salt dosing. In the first fibreglass-reinforced plastic tank, up to 1800 liters of saturated salt solution can be prepared. The saturated solution is then pumped to the second fibreglass-reinforced tank, where it is mixed with fresh water to reach the exact salinity required. The amount of saturated saline taken into the second tank is automatically adjusted to ensure the precise final salt concentration.
This final saline solution is heated using direct steam injection, with temperature control maintained via a thermoregulator feeler system, which adjusts the steam inlet valve. Vats with level feelers then feed the saline solution to the stretching machines.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
