Example

[0041]FIG. 1 generally illustrates a homogenizer 100, more particularly a homogenizer sold under the name Tetra Alex™ by Tetra Pak. Generally, the homogenizer 100 comprises two main parts, a high pressure pump and a homgenising device. The high pressure pump forms a high pressure and the homogenising device provides one or several gaps through which the product is forced with the effect that smaller fat globules are formed. Further effects of homogenization is more appetizing colour, reduced sensitivity to fat oxidation, more full-bodied flavour and better stability of cultured milk products.

[0042]In this example, the high pressure pump is a piston pump driven by a main drive motor 101 connected via a belt transmission 102 and a gearbox 103 to a crankshaft placed in a crankcase 104. By using the crankshaft the rotary motion is converted to a reciprocating motion driving pump pistons 105 back and forth. Today, it is common to have three to five pump pistons.

[0043]The pump pistons 105...

Abstract

A membrane comprises a main body having a first side and a second side. The main body is made of an elastic material in order to forward a pressure e.g. formed by a piston. On the second side it is provided a coating made of plastic material such that the main body is not affected by cleaning agents, abrasive products or the like coming in contact with the second surface.

Description

TECHNICAL FIELD[0001]The invention generally relates to the processing industry. More particularly, the invention relates to a piston pump arrangement suitable for hygienic applications, such as food processing, cosmetic product processing or pharmaceutical product processing.BACKGROUND OF THE INVENTION[0002]Today it is well known to use homogenizers within the food processing industry. For instance, within the dairy industry homogenizers are used for dividing fat globules into minor parts in order to obtain a stable fat emulsion against gravity separation. In other words, by homogenizing milk one can avoid that a cream layer is formed on top of the milk product. Other reasons for homogenizing food products are to achieve a more appetizing colour, reduced sensitivity of fat oxidation, more full bodied flavor, improved mouthfeel and better stability of cultured milk products.[0003]Generally a homogenizer can be divided in two main parts, a high pressure pump forming a high pressure a...
