Stage 1 rotary separators handle product with larger particles (up to 1/2") with up to 90% solids content.  Stage 2 separators handle product down to 500 microns for juice extraction.  All of our separators feature variable speed/flow rates and have optional Cleaning in Place.  The Laboratory Series replicates stages 1 and 2 in one machine for prototyping and process development

Stage 1 vs. Stage 2 Separators
Stage 1 and stage 2 separators are very similar in appearance, but have distinctly different applications. The stage 1 separator is designed to break up whole fruit or vegetables, so that the juices and pulp may be later separated from seeds, skins and stems. An impeller accomplishes the breaking down or macerating process by forcing product through a grid-like crusher partition. The screen section then separates seeds and other larger extraneous materials.

         While the single stage separation that is provided by the stage 1 separator might be sufficient for some applications, in most cases the pulp must be further refined. This is where the stage 2 separator is especially appropriate. The stage 2 separator is not equipped with an impeller or crusher partition. It is, however, equipped with screens that have much smaller perforations than those found in the stage 1 separator. The smaller screen perforations in the stage 2 separator allow the separator to efficiently separate tiny seeds and fibrous materials from pulp and juices. The stage 2 separator also discharges a highly refined and uniform product. One additional distinction is that the stage 2 separators are more commonly equipped with a product feed pipe inlet, while the stage 1 separator is usually equipped with a square or cone shaped hopper inlet. The unique Langsenkamp design allows the stage 1 separator to be converted for use as a stage 2 separator, providing the maximum flexibility.

Hopper or Pipe Inlet
 The type of inlet selected will depend upon the condition of the product to be processed. The hopper inlet is recommended for fruits and vegetables that must be shredded or broken prior to separation. The pipe inlet is recommended for hot-break products that are in a semi liquid condition.

  Our screens are constructed of either Monel or Stainless Steel. The size ranges are from 500 microns to .5 inches. The proper size depends upon the product and the process.
