Sulzer mixers for the food processing industry
Innovation as a flow line process
 

Technologies that point the way

Static mixers and mixing systems have a firm place in many industries. They are used for continuous processes and offer the customer a whole range of technical and economic advantages. Worldwide, Sulzer Chemtec is No. 1 in the branch and is repeatedly setting new standards based on innovative ideas.

Static mixing means homogenization without moving parts. In contrary to the dynamic mixing technology, the different components are mixed solely through the utilization of flow energy. The actual mixing effect is derived from the continuous split-off, expansion and redistribution of product flows, with the required energy being supplied by con- veyor units such as worms, pumps or blowers.

Decisive advantages

Sulzer mixers are based on an advanced method of construction with open, cross-over flow channels. This unique techno logy ensures that the mixing sequence is not random but takes place according to a predetermined geometric pattern and is thus reproducible. The result: increased efficiency, less energy consumption, lower operating costs. In addition, there are many other fundamental advantages:

  • The absence of moving parts. reduces downtime for servicing
    and repairs to a minimum.
  • The closed system permits totally hygienic product processing in
    in a germ-proof environment.
  • Low shear forces and the absence of gas overlays enable gentle processing in the shortestpossible time.
  • Semi-batch-processes can also be organized continuously, even when volumes are low.
The result: maximum flexibility, high security, no additional reservoir and products that are always fresh.
      And of the utmost importance:
  • Excellent cleaning-in-place characteristics (CIP)
  • No sealing problems
  • No production losses
  • No unwanted air inlet
  • Small volumes, short residence times
  • Low space requirement
  • Straightforward installation within existing plant
  • Low investment costs
The outlook is good

Accordingly, with our range of products,we are today in a position to offer you solutions for more than 60 applications that are guaranteed to meet your expectations in full. On request, we will even equip you with a suitable test unit.

  At a glance

Static mixing can be applied typically to the following basic processing technology operations:

  • The mixing of low-and high viscosity liquids
  • Dispersion of immiscible liquids
  • Homogenization of gas flows with regard to concentration or temperature
  • Intimate and intensive contacting of liquids with gases for increased mass transfer
  • Controlled reactions over a narrow residence time distribution

        Gentle heating of temperature-sensitive products, as well as cooling whilst applying a simultaneous mixing action

Systems that stimulate the appetite

The static mixer fulfills important tasks in the food processing industry. It is particularly suitable for mixing in additives such as fragrances, flavors and dyestuffs, minerals, trace elements, vitamins, emulsifiers and preservatives. Pasteurization and sterilization are further areas of application.                       
                                       
Sulzer Chemtech has the right solution for all mixing and reaction processes n the food industry. There are 5 dififerent mixer types covering the entire application spectrum. They can all betuned to the specific needs of individual customers. Low-viscosity, turbulent mixing
The SMV static mixer is primarily used for mixing low-viscosity media  (e.g. fruit juices with fragrances),   dispersing immiscible liquids (e.g.desliming vegetable oils with phosphoric acid) and contacting liquids with gas for mass transfer (e.g. the carbonisation of water

Benefits:

  • Saving in additives due to complete, immediate mixing
  • Simple separation and high mass transfer due to uniform, small drop-size/bubbles

Typical Applications:

         Beverage industry; oil and fat industry
 

Mixing of liquids containing solids

Sulzer's SMF mixer is used for mixing product flows that contain solids (e.g. fruit pieces in yogurt). The size, clear cross section in the tube and open structure design of the mixing chamber guarantee a reliable operation that is not prone to clogging - even less so thanks to the inclined guide elements which, in addition to actual mixing, allow a continuous flow of particles downstream.

Benefits:

  • No clogging when introducing fruit pieces or solid particles, and no destruction of the fruit structure

Typical Applications:

         Dairy processing industry
