For thermal solutions for viscous food the ViscoLine range is a series of highly efficient heat exchangers that have been designed to handle your food processes in the most gentle manner.

Introduction

The ViscoLineTM Multitube is the Alfa Laval hygienic heat exchanger
ideally suited for the heating, cooling and pasteurization of products
with low and medium viscosity, and products that contain fibersand small particulates.

Applications

These units are used in conjunction with a wide range of products, including milk, cream water, yellow fats, whole egg, egg white, egg yolk, fruit puree, baby food, many kind of fruit juices containing pulp and fibers, fruit concentrates, beer mash, tomato juice and nectar, protein solutions, yeast and soft drinks.

Benefits

  • Low maintenance costs
  • High working pressures
  • High working temperatures
  • Easy to expand
  • Easy to be inspected and cleaned.

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.

Otherwise the inner tubes would be smooth (especially designed for fouling or viscous fluids). The service media shell could be either smooth or 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 installation is maintenance free, thus eliminating any need for spare parts.

Technical data

Mechanical design pressure

The Viscoline Multitube Unit is designed for a pressure of 15 bar (217 PSI) on the product side (tubes) and 10 bar (145 PSI) on the service side (shell), depending on the connections. The unit can, however, accommodate higher pressure ratings, depending on component thickness as connection type. The ViscoLine Multitube unit complies with the European Pressure Equipment Directive (PED 97/23/CE), and is entitled to bear the CE mark. Where the CE mark is not required, Viscoline would be manufactured according to Sound Engineering Practice (SEP).

Other design codes are available as well such as ASME VIII Div.1 and others would be on request like SELO’s China Manufacturer License (SELO approval) and GOST Russia Certificate of Conformity. It is designed to operate at a temperature of 190°C (374 °F) although higher temperatures are also met. All units can be provided with an expansion joint to absorb any thermal expansion stresses that arise.

Connections

For both product side (tubes) and service side (shell) we can offer:
SMS, DIN 11851, DIN 11864, Tri-Clamps, Flange and other on request.
