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.
