Define the paste rather than a generic liquid
Describe the concentration range, formulation, filling temperature and viscosity where measured. These inputs help distinguish the transfer and filling duty from a low-viscosity juice application. Include the product range and any seasonal changes that need review. Model performance must be assessed under these stated conditions.
Coordinate paste transfer with filling
Review the product feed, connecting pipework, valves and filling head together. The supply must meet the filling sequence and the agreed inlet window. Confirm the response to a head stop or product interruption, including upstream control handover. Product sterilization is not supplied by the filling operation itself.
Drum handling and residue removal
For bag-in-drum projects, provide liner, drum and pallet details, not just nominal capacity. Include fitment support, weighing and filled-load movement. Identify cleaning access, product-contact dead spaces and the return circuit for the actual equipment. Cleaning and pre-sterilization have different objectives and need separate acceptance criteria.
PRACTICAL ANSWERS
Frequently asked questions
Can a juice filler be used for tomato paste?
Suitability requires a review of the paste’s flow behaviour, transfer duty, valve passages, package interface and cleaning circuit. A juice capacity rating is insufficient.
Are twin heads always needed for paste?
No. Compare the complete cycle and available product supply. A second position does not automatically overcome a transfer bottleneck.
Which details make an enquiry useful?
Send concentration, viscosity test conditions, filling temperature, target mass, bag fitment, drum or bin drawings and the required production target.
