Cleaning a blocked heat exchanger
Tube Tech international Clears A Sticky Situation
Industry sector: Food | Client: A confectionery company
The maker of world-famous confectionery brand names asked Tube Tech International to lick the problem of a blocked heat exchanger at its production plant in England.
Problem:
A shell and tube heat exchanger, which has chocolate running through the tube side, had become blocked. Solidified chocolate was affecting the performance of the heat exchanger, reducing the throughput. The siting of the heat exchanger in the centre of the plant offered special challenges for the Tube Tech team. Other equipment nearby and the distance from services such as water meant the cleaning team could not use conventional jetting systems.
Solution:
With the positional problem preventing water jetting Tube Tech International had to rethink the solution and opted for the SafeDrill™ system to clear the hardened chocolate but with only a minimal water flush. Finally the tubes were polished by Tube Tech’s RotaFlex™ system.
Benefits:
The Tube Tech team efficiently cleared the problem with little disruption to the regular workings of the confectionery factory. The decision to use the SafeDrill system meant less Tube Tech equipment being brought into the factory. The cleaning and polishing of the heat exchanger improved efficiency and achieved a greater throughput of chocolate.
Comments:
Tube Tech International Manager Scott Donson said: “The fact that the heat exchanger was in the centre of the plant prevented using the conventional jetting method and we had to make special arrangements to capture the chocolate waste which was drilled out.”
