. kyFrontLine™ Plate Heat Exchangers FrontLine™ Front plate . Applications • Pasteurisation • General cooling/heating of dairy, brewery, beverage and food products • Heating/cooling in the pharmaceutical industry. Standard design Frame The plates and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to the support column. The tightening bolts are equipped with ball bearing washers in order to facilitate opening and closing of the unit. The frame and support column have adjustable feet. One unit may contain several heat exchangers, separated by connection plates with interchangeable connections. The Front plate The Front plates are designed to meet the highest requirements in food processing. The combination of high pressing depth and a pattern with relatively few contact points provides longer operation time without interruptions. The distribution pattern assures an even flow over the entire plate. The ports have a diameter enabling cleaning in place (CIP) with the same flow used in the process itself. The plate pack The chevron corrugation of the plates provides a passage between the plates and supports each plate against the adjacent one. It also enhances the turbulence, resulting in efficient heat transfer. Different chevron angles are available to reach the optimal high heat transfer at a given pressure drop. A unique distribution area provides an efficient flow over the plate surface. The Alfa Laval hanging system enables easy handling of the plates in the frame. Furthermore the corner guiding provides a strong plate pack. The plates are reversible and have parallel flow, which means that only one type of gasket is needed. Working principle A Plate Heat Exchanger consists of a pack of corrugated metal plates with port holes for the passage of two fluids between which heat transfer will take place. The plate pack is assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the inter-plate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids and the temperature program. Connections may be located in frame plate and pressure plate.
