AlfaViscoLine Tubular Heat Exchangers

Alfa Laval offers a full range of tubular heat exchangers called the ViscoLine Series. This series of heat exchangers is a highly efficient tubular heat exchanger that uses corrugated tubes or other advanced profiles designed to increase turbulence. This means a substantially high rate of heat transfer (a higher l heat transfer coefficient). Higher turbulence reduces the formation of any fouling layers on the inner tube surfaces, and keeps the inner tube clean.

The Annular Unit
The ViscoLine Annular Unit is ideal for heating, cooling and pasteurization of products with high viscosity, and products that contain particulates. A tube in tube heat exchanger that is highly suitable for aseptic applications with steam purge and leak detectors. These tubular heat exchangers are Ideal for food products that are lowacid, such as tomato concentrate, banana paste, sourdough, chocolate sauce, mayonnaise, malt extract and tomato-based sauces in general.

Annular models are used at higher viscosity levels where it is necessary to apply heat to the product from both the inside and the outside at the same time, in order to prevent layering. In this tube-in-tube-in-tube model, the product flows between the inner and middle tube.

The Multitube Unit
The ViscoLine Multitube Unit is one of the most widely used thermal solution for viscous food. An ideal unit for heating, cooling and pasteurizing products with low and average viscosity, and products that contain fibres and small particulates. The tube plates have a conic tube hole to ease the flow of the product inside the tubes. These tubular heat exchangers 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.

The Monotube Unit
Products with low or average viscosity and also containing fibres, particles and particulates are often best heated or cooled with the ViscoLine Monotube, a tube-in-tube heat exchanger, where the the product medium flows inside the tube, and the service medium flows around it in a countercurrent direction. These units are most commonly used for fruit pulp, grape mash, wine must, fruit slurry, starch, diced tomato, diced vegetable and diced fruits, as well as sauces and soups that contain particles.

Monotube installations are most frequently used for heat-treating products that contain large particles, or have a high pulp or fibre content. The Monotube heat exchanger consists of a single tube mounted inside an outer shell.

The Multipass Unit
The ViscoLine MultiPass Unit is ideal for small flows and for the heating, cooling and pasteurization of products with low and average viscosity and that also contains fibres and small particulates. Bundles of tubes mounted in an outer shell the tubes in the multi pass unit can be arranged to allow two, three and six passes inside the shell by means of flow distribution headers at each end of the unit.

The Regenerator Unit
Specially designed for product-to-product heat exchange (recovery) the ViscoLine Regenerator Unit will save your energy requirements by transferring heat from the newly sterilized food product to the soon to be sterilized product.

The ViscoLine Regenerator Unit consists of a removable bundle of tubes mounted inside an outer shell, and welded onto tube plates at both ends. The sterilized product flows inside the bundled tubes, and the non-sterilized product outside, in counter-current flow. All tubes are connected in parallel.

The product flows counter-currently in the tubes and the media shell. This makes it possible to conduct product to- product regeneration. The ViscoLine Regenerator Unit consists of a removable bundle of tubes mounted inside an outer shell, and welded onto tube plates at both ends.
