Wine pump VX186: heat exchange recirculation
Case Study - La Torre di Castel Rocchero
Inefficient must cooling
Wine pump VX186-140Q
The customer and the problem
La Torre di Castel Rocchero is a renowned winemaking company that produces red wines (Barbera, Dolcetto), white wines (Cortese) and sparkling wines (Chardonnay, Moscato, Brachetto).
The company needed to optimize the operation of a tube-in-tube heat exchanger to cool must. The heat exchanger worked normally at around 3-4 bar and required very frequent soda washes.
Site manager Luca Mignano’s idea was to increase the rate at which the must was recirculated in to obtain a higher flow rate and decrease the rate at which the cool surface of the exchanger became “dirty.” Increasing the speed of the fluid being pumped concretely reduce how dirty the heat exchanger became and consequently how often it needed soda washing.
To obtain these results, a VX136-140Q pump installed with a 15 kW motor capable of pump a flow rate of approximately 300 hl/hour at a pressure of 5 to 6 bar was installed with very good results.
