When I have done my CIP on the whole system, also on the heat exchanger I'm 100% sure that it's clean so that the next batch is safe. My name is Palle Melchart. I work for Alfa Laval with heat transfer, specifically in the food industry. Part of my job is visiting customers all over the world who are in dairy or any kind of beverage or fruit drink processing. It's very important for them that the heat exchanger is fit for purpose that it's actually developed for hygienic food applications. Both from an efficiency point of view and from a safety point of view it's important to them that it's not just an adapted industrial heat exchanger. Talking about cleanability – for our customers in the hygienic food industries food safety is extremely important. And of course, everything in the entire process needs to be able to be cleaned down to the smallest organism – it needs to be gone between each batch including the heat exchanger, of course. So, it's very, very important that when we design a plate for hygienic food industries that the cleanability is really, really good, so that the customer can have this safety. They feel the safety and they have the peace of mind: when I have done my CIP on the whole system, also on the heat exchanger I'm 100% sure that it's clean so that the next batch is safe. Easy maintenance is a combination of all the parts that a heat exchanger consists of. It's the frame, the plates, the bolts and nuts – everything. So, it's very important that many of these parts have serviceability built into them. And it has to be easy to work with from a maintenance point of view so that you can easily open it by yourself and you don't need to have more people. It has to be to be easy to do it when you close the heat exchanger after gasket change or any kind of service intervention. It needs to be easy to do it right the first time. Unplanned shutdowns is something that all our customers want to avoid – because it will really disturb the entire process and it jeopardizes their profitability if they're not delivering their product on time, etc. So, from a heat exchanger perspective it's very important that it's doing its duty and we don't have this kind of unplanned shutdowns.
