Dry Salt Dosage Systems
GEA can configure dry salt dosage systems with tank capacities of 150-300 kg dry salt. Each unit in our portfolio is designed to be energy efficient, and promise low operating and maintenance costs.
Dry salt dosage systems from GEA are constructed around a double truncated cone-shaped dry salt vat, which is kept in constant rotation to help stop the salt clumping, and is heated via an external jacket.
The tank contains spoons that scoop the salt into a hopper, from where it is transferred to a conveyor pipe. At the end of this pipe a variable-speed auger system transfers the salt to the curd coming out of the stretching machine. The curd cheese is transferred to a Teflon-coated chute in which it is flattened by an adjustable paddle. The cheese is transported along this chute to a rotating drum. A sensor system automatically detects the thickness and speed of the stretched pasta filata as it moves along the chute, and this data is sent to a PLC that adjusts the speed of the salt distribution auger, to ensure that the precise amount of salt is dosed then dosed. The cheese and salt are combined in a rotating drum and transferred to a kneading unit that contains counter-rotating augers. From here the salted pasta filata cheese is transferred to the molding station.
The cheese and salt mixing tunnel can be configured with pipework for connection to a cleaning-in-place (CIP) plant. Whey and cleaning solutions from CIP are collected in a vat that is connected to a centrifugal pump. Servo-motor drives operating the salt distribution and mixing augers guarantee precise, reliable operation.
Offering automated adjustment and fine control, GEA salt dosage systems are accurate to within 0.1% salt dosing. The units are constructed using stainless steel AISI 316 to withstand the corrosive activity of salt.

Smart, stylish, circular: polycotton recycling with Circ
Resource-efficient fashion has been a long-sought ambition amid the fashion industry’s considerable contributions to global carbon emissions. The need to close the loop by recycling textile fibers into virgin-like materials is higher than ever but seemed like a distant dream until now: Circ, GEA’s American customer and pioneer in the field of textile recycling, might be rewriting the future of the fashion industry.
New food tipping point
Alternative proteins are promising – yet still expensive to produce. The usual response is that scaling up will solve this issue. But what if the solution was really about getting better, not just bigger? From more efficient, high-yield processes to upcycling waste heat, engineers are reshaping how we grow food.
