Static Mixer

Static hygienic mixers and heat exchangers are solutions for mixing, cooling, frothing, dispersion and pasteurisation of foods and beverages.

Within the food industry aspects as CIP cleaning, smooth and / or polished surfaces and sanitary fittings, are of importance. Therefore, by applying static mixing elements and by the achieved increased product velocity alongside the inner wall of the tube. The applied mixing element with respect to an empty tube after CIP Cleaning, provides a considerably cleaner result. Finally the subsequently measured bacterial count is minuscule.

In-line mixers introduce or remove heat from a product stream without the need for plate heat exchangers (which cannot work on high viscosity products and are difficult to clean) or excessively long shell and tube units.

The mixing elements are fully welded and electro-polished making them the cleanest available
Tailor made units
Supplied with or without heating/cooling jackets
Up to 4 injectors in a single housing
Intelligent design and pulse free flow allow us to make shorter mixers, minimising waste

Marble chocolate – white and brown chocolate

A particular application in which static mixers have proven to be very useful, is marbling chocolate. Firstly, in a chocolate flow a relatively smaller current of white chocolate is blended. As it stays in the laminar flow area, layers as described above arise, and this gives the beautiful marble effect. Secondly, the static mixer also lends itself perfectly to mixing air into chocolate. and this is called of two-phase mixing.

Re-work margarine

Many margarine installations in Europe run with a re-work section. In the feeding pipeline to the packaging machine a relatively small flow of margarine is returned, so that it is always on standby. Should a sudden failure of the packaging line occur, the full capacity of the cold margarine (6 ° C) will go through the re-work installation and return melted to the storage tank. Systems with warm water as well as those with steam work very satisfactorily.

Pasteurising and cooling sauces

Separated or mixed, an oil / water / starch mix is brought to the desired pasteurisation temperature by means of indirect steam heating. The hold phase may take place three times more quickly as a result of the fact that the mixing runs continuously. Thus, not a single particle can escape the heat treatment. Cooling to packaging temperature takes place by means of cold water, therefore, the entity forms a closed system, which is very easy to sterilise and to CIP clean.

Offal pasteurization – homogeneous mixing and temperature distribution

Liquid offal – valuable due to the high content of protein, fat and minerals – is thermally treated after the separator. This is a continuous process with an automatic interim CIP cleaning.

Pasteurisation of concentrated fruit – fast heating and cooling

To preserve taste in pasteurisation and sterilisation processes can be achieved by bringing the product to a high temperature quickly, keeping it there and then cooling it down quickly again. Fast heating and cooling is achieved by the mixing elements, because these promote exactly the right degree of refreshment on the heat-exchanging surface. Furthermore, well known food manufacturers are using these mixing elements very successfully, allowing the sterilisation sections to be built considerably smaller and thus improving efficiency.

Bottom entry mixers meet all requirements in product dispersing, mixing, homogenising, and crushing processes.

The EMF mixers are installed in the bottom of the vessel and carry out highly efficient dissolving of the heaviest particles of the product. When turning, the turbine generates the suction required to draw the fluid towards the centre of the headpiece, where centrifugal force directs it toward the outside of the rotor. Once the space between the turbine and the stator is reached, the product is subjected to high pressure which leads to crushing. It then passes through the high turning speed headpiece orifices, generating a very high shearing strain which leads to dispersion, emulsification and homogenisation of the mix, as this process is repeated continuously.

The high level of shearing combined with the different types of headpieces (perforated, slotted, or sieved), generates the ideal particle size for stable emulsions and homogeneous mixes. These units can be used if an agitator system is fitted with an anchor impeller for high viscosity products, or can work alone if the product has low viscosity. In addition, all these features make the units essential in sectors as demanding as the food, pharmaceutical and cosmetic industries.

Solid -liquid emulsifiers EMTE with its rotor stator system optimised design altogether with its suction system, give homogenous mixtures of liquids with powders and granulated products. the simplicity of the parts and the connections ensure highly hygienic operation conditions.

The operating principle of this system is found in the suction generated by the quick circulation of the fluid through the feeder thank to the ventury effect, making powder suction easier. The mix enters the central part of the impeller and once inside, is dispersed through the diffuser orifices, where it is crushed and dispersed to obtain a completely homogeneous product. This way, the dissolution procedure is optimised achieving homogenous product with or without product recirculation.

Once it has been completely homogenised by rotor-stator system, the reverse turbine impeller provides the impulsion pressure necessary to pump the product towards the next unit, and also generates the suction necessary during operation.

The solid incorporation system prevents product moistening, thickening and solidification, thus avoiding any operation problems resulting from the appearance of agglomerations in the load.

Their performance makes them ideal for working with food, cosmetics and pharmaceutical industries. Some examples of operations where EMTE mixers are used are as follows:

Dissolving of sugar in food (wine, syrup, condensed milk, ice cream etc)
Preparation / reconstitution of powdered milk
Brine preparation
Syrup production
Dissolving of bentonites, tannins, thickeners, active carbon etc
Incorporation of additives, colourants, flavourers, agrochemical products, lime etc

Solid Liquid Mixers EMTB, with the optimised design of the blade and suction system, produce completely homogenised mixtures of powders or granulated products with liquids. The simplicity of the parts and the connections system facilitate maintenance tasks and ensure highly hygienic operation conditions.

The main fluid is pumped and carried through the mixing chamber, creating the suction required in order to add the solid, which is mixed violently to produce dissolution. Finally, all the powder is added, the regulation valve is closed and, after several circulations, a completely homogenised mixture is obtained. This solid incorporation system prevents product moistening, thickening and solidification, thus avoiding any operation problems resulting from appearance of agglomerations in the load.

EMTB performance makes them ideal for working in the food, cosmetic, and pharmaceutical industries. Some examples of operations where EMTB mixers are used as follows:

Brine preparation
Reconstitution of powdered milk
Syrup production
Dissolution of bentonite, thickeners, sugar etc
