The Primodan GDL Mixing Unit
When producing white cheese fermented not by culture but by the acidifying agent known as GDL (Glucono – Delta – Lactone) powder - it is necessary to mix the powder into the cheese milk prior to filling the product.
Primodan has extensive experience in producing GDL mixers for this application, which run inline with the filling machine regardless of whether it is a Tetra Pak carton/brick machine, a SIG combibloc machine or a Primodan cup or canister filling plant.
In our system, we are able to not only mix in GDL powder but also to mix in salt in the same unit, thereby removing the need for pre-salting tanks.The units are produced as semi-automatic or fully automatic depending on the customer´s preference.
Both types are fully CIP cleanable from the customers CIP plant. As an additional feature Primodan offers in-line flavor mixing units, which can be connected to the GDL mixer for mixing in flavor inline before the filling machine.
When mixing GDL powder or salt in this unit the design ensures good mixing.
Since the design of this unit is made with the mixing tank on top of the buffer tank the footprint is limited.
The mixing unit is produced in a hygienic design and is naturally CIP cleanable from the clients CIP plant.
Primodan has supplied a vast number of these mixing units to be connected to filling lines from SIG combibloc, Tetra Pak and naturally Primodan filling lines.
