TYPES OF MIXERS AND SEPARATORS

SHEAR PUMPS - MIXERS

OVERVIEW

Shear pumps are designed for “on-line” continuous shearing and mixing action. They are very versatile due to their interchangeable stators and rotors. This results in being able to process a wide variety of products. Additionally, variable speed drives may also be used to further adjust the shear and mixing effect. A shear pump is able to texturize which results in a smooth body and texture to such products as ricotta cheese and food pastes. They can also emulsify to make stable emulsions of products with both oil and water based ingredients; blends to provide continuous, on-line blending without air incorporation or lumps of dry product; reconstitutes to assist reconstitution of powdered products such as milk powders; suspends/disperses to give stable solids in liquid suspension; polishes to improve the appearance of products by providing a smoother and more uniform surface texture.

COLLOID MILLS - MIXERS

OVERVIEW

The process of shearing/mixing produce controlled, highly sheared, uniform dispersions, and stable emulsions. As a result, there is a wide range of product viscosity that may be processed.  The viscosity is limited only by the maximum 150 psig (10 bar) inlet pressure. The higher viscosity products are processed at lower flow rates to stay within the pressure limit.

  • Easy to adjust
    • Calibrated ring sets spacing
    • No special tools
    • Less downtime
    • May be adjusted while operating
  • Easy to disassemble
    • Only 7 basic parts

CR MIXER - MIXERS

OVERVIEW

CR Mixers have patented high-shear mixing technology that produces uniform, stable emulsions, dispersions, and foams. They combine product recycling and shear action that can be “tuned”. This produces the precise effect desired. The number of passes the product makes through the mixing zone is determined by the varying rotor speed and controlling back pressure. For heat-sensitive products (e.g., eggs, latex), incremental mixing moderates temperature rise.

  • Precise, fast, economical mixing
  • Overruns beyond 300%
  • Full control over amount, intensity, duration of mixing, blending, dispersing, beating or whipping action
  • Incremental mixing for heat-sensitive products
  • Process-matched to broad range of products
    • Liquid-liquid, liquid-gas, liquid-solids
  • Ideal for both continuous in-line use or side-arm, sequence use in batch operations

SELF-CLEANING SEPARATORS

OVERVIEW

SPX FLOW offers a wide range of self-cleaning separators for liquid/liquid/solid separation. This type of separator allows for the recovery of fine particles (0,5-500 µm), efficient separation of a mixture into its two phases, and the contemporary clarification of both by means of a very high peripheral centrifugal field (G-force).

PROCESS BREAKDOWN

  1. The product that needs to be treated flows into the bowl through a feed pipe and into the distributor
  2. Undergoes acceleration until it reaches the bowl rotating speed
  3. The distributor conveys the product to the disk stack where the separation between the light and heavy phase takes place
  4. Light clarified phase flows to the center of the bowl
  5. Heavy phase flows to the bowl’s outer diameter
  6. Both phases rise in the disk stack and reach the two upper chambers of the bowl
  7. Two fixed centripetal pumps convey them under pressure to the outlet pipelines
  1. The separated solids are collected in the peripheral part of the bowl and are periodically discharged through the discharge holes
  2. Discharged solids are collected into an outer annular chamber connected to a damping sludge tank where they are drained away by gravity through a pipe
  3. The pressure produced by water in chamber keeps the hydraulically operated ram in a closed position
  4. Water is fed into pipeline, and the bowl valve allows water in chamber to flow away
  5. The product pressure pushes down the hydraulic ram and the solids are immediately ejected through the discharge holes
  6. By stopping the opening water feed and filling the closing water line into the chamber opening, the hydraulic ram goes back to the closed position
  1. The periodic solids discharge are carried out automatically by means of a PLC.
    • Controls the opening and closing water solenoid valves and the solenoid valves of the operating water circuit
  2. Various automatic, independent working cycles may be selected to perform partial and/or total discharges during separation and cleaning procedures
  3. PLC is set to make it possible to adjust the discharge volume, the frequency, and the combination between partial and total discharges
    • The PLC can also perform the following functions:
      • Automatic bowl closing during the starting phase
      • Stop feeding during total discharges
      • Rinsing of all internal surfaces before and after the discharge
      • Manual control of partial and total discharges
      • Bowl overflow (during CIP)
      • Product re-circulation
 

SELF-CLEANING CLARIFIER

OVERVIEW

SPX FLOW Seital Separation offers a wide range of self-cleaning clarifiers for liquid/solid separation. The clarifier allows the recovery of fine particles (0.5-500 m), and/or a strong clarification of liquids by means of a very high peripheral centrifugal field (G-force).

PROCESS BREAKDOWN

  1. The product to be clarified flows into the bowl through a feed pipe and into the distributor
  2. Undergoes acceleration until it reaches the rotating speed of the bowl
  3. The distributor conveys the product to the disks stack where the clarification takes place
  4. The clarified liquid rises in the disks stack and reaches the upper chamber of the bowl
  5. A fixed centripetal pump conveys it under pressure to the outlet pipeline
  6. A hydraulic sealing device prevents product oxidation due to ambient air
  1. Separated solids are collected in the peripheral part of the bowl and are periodically discharged through the discharge holes
  2. The discharged solids are collected into an outer annular chamber connected to a damping sludge tank where they are drained away by gravity through a pipe
  3. The pressure produced by water in chamber keeps the hydraulically operated ram in a closed position
  4. Water is fed through the pipeline, and the bowl valve allows the water in the chamber to flow away
  5. The product pressure pushes down the hydraulic ram and the solids are immediately ejected through the discharge holes
  6. By stopping the water feed and filling the closing water line into chamber opening, the hydraulic ram goes back to the closed position

SOLIDS RETAINING SEPARATORS

OVERVIEW

SPX FLOW Seital Separation offers a wide range of solids-retaining separators for liquid/liquid/solid separation. They have very low solids content in the feed (less than 0.2% in volume). This type of separator allows efficient separation of a mixture into its two phases and the recovery of fine particles (0.5-500 m). These two phases are done by means of a very high peripheral centrifugal field (G-force). The separation process takes place in the bowl of the high speed separator.

PROCESS BREAKDOWN

  1. Product flows into the bowl through a feed pipe and into the distributor 
  2. Undergoes acceleration until it reaches the bowls rotating speed
  3. The distributor conveys the product to the rising channels of the disks stack where the separation between the heavy and light phases takes place
  4. The high number of disks divides the internal space of the bowl into many thin layers, making the separation process more efficient
  5. The light phase flows towards the center of the bowl and leaves the disk assembly via its inner edge
  6. The heavy phase flows towards the bowls periphery
  7. Both phases rise in the disk stack and reach the two upper chambers of the bowl where two fixed centripetal pumps convey them under pressure to the outlet pipelines.
  8. The two pumps are surrounded by rotating liquid phases, and they transfer the speed of the liquid into static pressure
  1. The solids impurities present in the product are collected in the periphery of the bowl where they must be removed manually
  2. If the solid phase is consistent, the solids sedimentation is relatively fast, so the machine must be periodically stopped for the removal
  3. If solids are adhesive and very compact, Seital series separators may be equipped with a collection basket
    • Permits faster removal of relatively dry solids
  4. Valves and instrumentation that are necessary to control and regulate the separator (micrometric adjusting valves, manometers and sight glasses) are outfitted on inlet and outlet pipelines
    • Ensures proper operation
