Text version of the page

ViscoLine™ Multitube Unit The tubular heat exchanger series from Alfa Laval Applications The ViscoLineTM Multitube unit is ideal for the heating, cooling and pasteurization of products with low and average viscosity, and products that contain fibres and small particulates. These units are used in conjunction with a wide range of products, including milk, water, yellow fats, whole egg, egg white, egg yolk, fruit purée, baby food, many kinds of fruit juices containing pulp, fruit concentrates, beer mash, tomato juice and nectar, protein solutions, yeast and soft drinks. Standard design The ViscoLine Multitube unit consists of a bundle of tubes mounted inside an outer shell, and welded onto tube plates at both ends. The product medium flows inside these tubes, and the service medium between and around them. All the product tubes are connected in parallel and so that the flow is counter-current in relation to the service medium. If required, these product tubes can feature a corrugated surface with either hard or dimple patterns. The service media shell is hard corrugated. ViscoLine Multitube modules are normally connected in series and grouped on a common frame. The eccentric reducers can be welded, clamped or flanged. The tube plates have a conic tube hole to ease the flow of the product inside the tubes. The installation is maintenance free, thus eliminating any need for spare parts.
