FAQs Agitation and In-Line Mixing

  • How do I know which agitator I need for my mixing process?

    You don’t need to know, we take responsibility for offering you the right agitator based on: 50 years of experience, our calculation programs, ANSYS simulation and our pilot plant. At VK we give double guarantees to our mixing equipment: mechanical and process.

  • What is a counter-rotating agitator?

    It is an agitator that has two systems of blades, intermediate blades and an outer anchor with scrapers, on the same axis rotating in opposite directions between them. They have independent motor-reducers and are suitable for very high viscosity products and mixing, homogenization and heat exchange processes.

  • When would you choose a Side-entry agitator?

    Side-entry agitators are suitable for simple homogenization processes and for low viscosity products.

  • When is the use of deflectors necessary?

    When we work with products of low or medium viscosities and with centered agitators, two phenomena occur, the product rotates and vortex is produced so that no turbulence or mixing is generated. The way to avoid these two phenomena is to install baffles in the tank. For low viscosity products, there is the option of offsetting the agitator without the need to install baffles.

  • Can Vak Kimsa design equipment for sterile or aseptic processes?

    We have agitators with sterile or aseptic designs with mechanical seals suitable for these working conditions, external couplings to the tank and 320 + electropolished grain surface finishes.

  • How can I mix without incorporating air?

    Working under vacuum guarantees 0% air in the mix. Working atmospherically, an agitator with a suitable design with large paddle diameters and low speeds minimizes the entry of air. Likewise, working through an ML also reduces the entry of air into the mix.

  • When would you choose an In-Line mixer?

    For dissolution, dispersion and emulsion processes. for large volumes or for products that are difficult to mix.

  • What are the advantages of an In-line mixer?

    We can mention up to 10 advantages over a traditional agitator:

    • Lump-free products.
    • Air-free products.
    • Lower power rating than with a conventional agitator.
    • Flexibility in batch volume.
    • One single mixer for production in several tanks.
    • Loading of components from floor level.
    •  Deposits free of solids adhered to its walls.
    •  Total dissolution of hygroscopic solids.
    •  Low granulometry dispersions.
    • Small particle size emulsions.

  • What is the difference between batch and continuous manufacturing?

    Manufacturing in batches with a ML is carried out by means of a tank in which the product recirculates on it. For continuous manufacturing it is necessary to have the raw materials stacked, to dose them directly to the mixer head, the mixture already made coming out directly in the necessary proportions.

  • How can I get rid of agglomerates in my mix?

    MLs ensure that no lumps form as solid and liquid come into contact right at the mixing point, drastically reducing manufacturing times.

  • How can I be sure my mixing process is going to work?

    At VK we base the success of the mix on 4 props: 50 years of experience, our calculation programs, the ANSYS simulation and our pilot plant. At VK we offer double guarantee to our mixing equipment: product and process.

  • Can Vak Kimsa supply equipment anywhere in the world?

    Of course! Our market is the world. We have equipment installed in more than 40 countries.

  • Does Vak Kimsa offer remote technical assistance?

    Of course! current technology allows remote technical assistance to be performed between 1 and 24 hours, depending on the time difference.
