Juice flows slower than water so as not to foam or tear the fine pulp: we take about 1.2 m/s. For 5 m³/h an inner diameter of about 38 mm is needed, and the nearest standard food pipe DIN 11850 is DN50.
Approximate calculation using a simplified model: for designing equipment and process modes, consult a technologist.
Why is the velocity lower for juice?
High velocity increases foam and shear and harms quality; for thick products the velocity is even lower.
The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
