Used dairy machines include hygienic fillers for refrigerated and extended-shelf-life products, aseptic filling systems, rotary and linear fillers for HDPE and PET containers, carton filling machines, and the cappers or sealers that go with each package.
Aseptic packaging requires a commercially sterile product, a sterile package and a sterile filling environment. Refrigerated products follow a different process, so the two families of machine are not interchangeable without engineering review.
Buying Guide — Used Dairy Bottling Machines
Hygienic design comes first: product-contact materials, drainability, absence of dead legs, and CIP or SIP capability as applicable to the machine. Ask which hygienic-design documentation and standards are relevant for your destination market and process, and what exists for that unit.
On aseptic machines, examine the sterilisation system and the filling environment, and ask for validation, commissioning or service documentation. On machines for refrigerated products, focus on the filling environment, cleaning regime and container handling.
Confirm the package and container formats the machine covers, the closure or sealing system, the change parts included, and the manuals and drawings supplied.
Frequently asked questions
What distinguishes an aseptic dairy filler?
It is built to fill a commercially sterile product into a sterile package inside a sterile filling environment, which requires a sterilisation system and a controlled filling zone.
Which hygienic standards should I check?
It depends on the process and the destination market. Identify the relevant hygienic-design documentation and standards for your case and check what documentation exists for the specific machine.
Which containers can be used?
HDPE, PET, glass and carton are all common in dairy; the machine is built around a specific package family and format range.
