Big bag filling
Automatic, hygienic and low construction height
After spray drying, the customer wanted a quick and efficient big bag filling. Mostly a reversing auger or a Y-pipe with a two-way valve is used, where simultaneously the full big bag is exchanged with an empty, while the other big bag is being filled.
However, there can be several problems with augers and Y-pipes. Firstly, they require significant extra construction height, which sometimes is an impossibility. Secondly, sometimes the product is so fragile that it cannot go through a screw or and y-pipe with two-way valve. Finally, the problem is that both augers and two-way valves can never be considered 100% sanitary, i.e. some cross-contamination will occur.
