Viscosity needs a temperature
A viscosity value is only useful alongside its measurement conditions. Send information for the coldest and warmest intended filling conditions, where available. Record solids or concentration and describe fibre or suspended material. Identify differences across the product range rather than specifying only a typical recipe.
Review transfer and filling together
The upstream supply must deliver the required flow without compromising the product or the defined sterile path. Review the pump, pipework, valve passages and head inlet as one transfer duty. Consider pressure loss and the final stopping sequence. Do not infer achievable output from a rating measured with a different liquid.
Plan a representative product trial
Specify the actual bag, cap and supporting container for the trial. Compare net-fill variation, closure condition and the complete work cycle. Include cleaning access and residues in product-contact components. Acceptance should cover the limiting product in the intended range and clearly identify conditions that remain outside the tested envelope.
PRACTICAL ANSWERS
Frequently asked questions
Are purée and concentrate interchangeable specifications?
No. Concentration, temperature, fibre and flow behaviour can differ. Describe each product and the intended operating conditions.
Which head arrangement is better for purée?
Match head count to available product flow and package-handling time. Twin heads help only when the supply and sequence support the intended overlap.
What product data should I supply?
Provide viscosity and its test conditions, concentration, fibre or particles, fill temperature, target mass and the required production window.
