Continuous post-addition: a new way of understanding liquid product manufacturing<\/h2>\n

Every finished-product tank means one more cleaning cycle. What if you needed far fewer? Your plant may not need one tank for every SKU: a single 1,000-litre concentrate tank can generate up to 40,000 litres of final product.<\/h4>\n

For many years, liquid product manufacturing has been based on a batch production model: each formula is prepared in a tank, all the components are mixed, the finished product is stored and then transferred to the packaging line.<\/p>\n

This model remains a valid solution for many applications. But when a plant has to manufacture more and more SKUs, adapt to frequent formulation changes or reduce downtime, \ud835\uddfb\ud835\uddf2\ud835\ude04 \ud835\uddf0\ud835\uddf5\ud835\uddee\ud835\uddf9\ud835\uddf9\ud835\uddf2\ud835\uddfb\ud835\uddf4\ud835\uddf2\ud835\ude00 \ud835\uddee\ud835\uddfd\ud835\uddfd\ud835\uddf2\ud835\uddee\ud835\uddff:<\/p>\n

\u2022 Multiple tanks dedicated to different products.
\u2022 Greater use of floor space in the factory.
\u2022 More cleaning operations.
\u2022 Less flexibility in the face of changes in demand.<\/p>\n

Faced with this reality, \ud835\uddf0\ud835\uddfc\ud835\uddfb\ud835\ude01\ud835\uddf6\ud835\uddfb\ud835\ude02\ud835\uddfc\ud835\ude02\ud835\ude00 \ud835\uddfd\ud835\uddfc\ud835\ude00\ud835\ude01-\ud835\uddee\ud835\uddf1\ud835\uddf1\ud835\uddf6\ud835\ude01\ud835\uddf6\ud835\uddfc\ud835\uddfb proposes a new way of manufacturing: separating the preparation of the common base from the final customisation of the product.<\/p>\n

From stored finished product to made-to-order product<\/h4>\n

The main idea is simple: not all components of a formulation have the same function.<\/p>\n

Some ingredients are part of the common base of different products, while other elements provide the final differentiation: fragrances, colours, preservatives or other formulation adjustments.<\/p>\n

\ud835\udde3\ud835\uddfc\ud835\ude00\ud835\ude01-\ud835\uddee\ud835\uddf1\ud835\uddf1\ud835\uddf6\ud835\ude01\ud835\uddf6\ud835\uddfc\ud835\uddfb \ud835\uddfa\ud835\uddee\ud835\uddf8\ud835\uddf2\ud835\ude00 \ud835\uddf6\ud835\ude01 \ud835\uddfd\ud835\uddfc\ud835\ude00\ud835\ude00\ud835\uddf6\ud835\uddef\ud835\uddf9\ud835\uddf2 to separate these two concepts.<\/p>\n

First, a concentrated intermediate is manufactured in a reactor. Then, this concentrate is continuously combined with:<\/p>\n

\u2022 The \ud835\ude04\ud835\uddee\ud835\ude01\ud835\uddf2\ud835\uddff needed to reach the final concentration.
\u2022 The \ud835\uddfa\ud835\uddf6\ud835\uddfb\ud835\uddfc\ud835\uddff \ud835\uddf0\ud835\uddfc\ud835\uddfa\ud835\uddfd\ud835\uddfc\ud835\uddfb\ud835\uddf2\ud835\uddfb\ud835\ude01\ud835\ude00 that define each SKU.<\/p>\n

The mixture is dosed and the necessary final adjustments, such as pH, are made.<\/p>\n

Finally, all the components are continuously mixed until the final product is obtained, which is then sent to the packaging line. \ud835\udde7\ud835\uddf5\ud835\uddf2 \ud835\uddff\ud835\uddf2\ud835\ude00\ud835\ude02\ud835\uddf9\ud835\ude01 \ud835\uddf6\ud835\ude00 \ud835\uddee \ud835\uddfa\ud835\uddfc\ud835\uddff\ud835\uddf2 \ud835\uddf3\ud835\uddf9\ud835\uddf2\ud835\ude05\ud835\uddf6\ud835\uddef\ud835\uddf9\ud835\uddf2 \ud835\uddfd\ud835\uddf9\ud835\uddee\ud835\uddfb\ud835\ude01, \ud835\uddef\ud835\uddf2\ud835\ude01\ud835\ude01\ud835\uddf2\ud835\uddff \ud835\uddee\ud835\uddef\ud835\uddf9\ud835\uddf2 \ud835\ude01\ud835\uddfc \ud835\uddee\ud835\uddf1\ud835\uddee\ud835\uddfd\ud835\ude01 \ud835\ude01\ud835\uddfc \ud835\uddfa\ud835\ude02\ud835\uddf9\ud835\ude01\ud835\uddf6-\ud835\udde6\ud835\uddde\ud835\udde8 \ud835\uddfd\ud835\uddff\ud835\uddfc\ud835\uddf1\ud835\ude02\ud835\uddf0\ud835\ude01\ud835\uddf6\ud835\uddfc\ud835\uddfb.<\/p>\n

A more flexible plant: different products from a single base\u00a0<\/h4>\n

One of the great advantages of post-addition is the possibility of manufacturing different final products without needing a specific tank for each formula.<\/p>\n

The same concentrate can give rise to different products \ud835\uddef\ud835\ude06 \ud835\uddf0\ud835\uddf5\ud835\uddee\ud835\uddfb\ud835\uddf4\ud835\uddf6\ud835\uddfb\ud835\uddf4 \ud835\uddfc\ud835\uddfb\ud835\uddf9\ud835\ude06 \ud835\ude01\ud835\uddf5\ud835\uddf2 \ud835\uddf0\ud835\uddfc\ud835\uddfa\ud835\uddfd\ud835\uddfc\ud835\uddfb\ud835\uddf2\ud835\uddfb\ud835\ude01\ud835\ude00 \ud835\uddee\ud835\uddf1\ud835\uddf1\ud835\uddf2\ud835\uddf1 \ud835\uddf0\ud835\uddfc\ud835\uddfb\ud835\ude01\ud835\uddf6\ud835\uddfb\ud835\ude02\ud835\uddfc\ud835\ude02\ud835\ude00\ud835\uddf9\ud835\ude06.<\/p>\n

This allows you to:
\u2022 Change formulas more quickly.
\u2022 Manufacture large or small batches as needed.
\u2022 Respond better to variable market demand.<\/p>\n

The plant stops being a rigid installation and becomes a more adaptable production platform.<\/p>\n

Fewer tanks, more production capacity<\/h4>\n

Reduced storage requirements are another differentiating point.<\/p>\n

In a traditional system, each SKU may require its own storage space. With post-addition, the same concentrate can feed different final formulations.<\/p>\n

For example, the VK solution means that \ud835\uddee \ud835\udfed,\ud835\udfec\ud835\udfec\ud835\udfec-\ud835\uddf9\ud835\uddf6\ud835\ude01\ud835\uddff\ud835\uddf2 \ud835\uddf0\ud835\uddfc\ud835\uddfb\ud835\uddf0\ud835\uddf2\ud835\uddfb\ud835\ude01\ud835\uddff\ud835\uddee\ud835\ude01\ud835\uddf2 \ud835\ude01\ud835\uddee\ud835\uddfb\ud835\uddf8 \ud835\uddf0\ud835\uddee\ud835\uddfb \ud835\uddf4\ud835\uddf2\ud835\uddfb\ud835\uddf2\ud835\uddff\ud835\uddee\ud835\ude01\ud835\uddf2 \ud835\ude02\ud835\uddfd \ud835\ude01\ud835\uddfc \ud835\udff0\ud835\udfec,\ud835\udfec\ud835\udfec\ud835\udfec \ud835\uddf9\ud835\uddf6\ud835\ude01\ud835\uddff\ud835\uddf2\ud835\ude00 \ud835\uddfc\ud835\uddf3 \ud835\uddf3\ud835\uddf6\ud835\uddfb\ud835\uddee\ud835\uddf9 \ud835\uddfd\ud835\uddff\ud835\uddfc\ud835\uddf1\ud835\ude02\ud835\uddf0\ud835\ude01, reducing the need to hold large volumes of stored finished product.<\/p>\n

    The in-line mixer: the key component of the process<\/h4>\n

    In a post-addition system,\u00a0the final quality of the product depends on effective, homogeneous mixing.<\/p>\n

    This is where in-line\u00a0mixing technology takes centre stage.<\/p>\n

    VK systems integrate \ud835\udddf\ud835\udddc\ud835\udde9\ud835\uddd4\ud835\uddde in-line mixers, responsible for the dilution and\u00a0homogenisation of the different components during the continuous process<\/p>\n

    Unlike a traditional process based solely on residence time inside a tank, continuous mixing makes it possible to control the process at the very moment the components are incorporated.<\/p>\n

    This is especially interesting for products where uniformity, repeatability and control of final properties are critical factors.<\/p>\n

    \u00a0<\/p>\n

    Precise dosing and process control<\/h4>\n

    VK post-addition incorporates continuous dosing systems through instantaneous flow measurement and pH regulation, ensuring that each component enters in the intended proportion.<\/p>\n

    The system can be integrated with plant control via PLC, making it possible to manage recipes, control process variables and ensure the traceability of each production run.<\/p>\n

    This automation provides:<\/p>\n

      \n
    • Repeatability <\/b>between batches.<\/li>\n
    • Less dependence<\/b> on manual handling.<\/li>\n
    • Greater control <\/b>over the components used,<\/li>\n<\/ul>\n

      Less handling of minor components<\/h4>\n

      Minor ingredients require a lot of handling.\u00a0With post-addition, these components can be dosed directly from their original containers, avoiding unnecessary handling.<\/p>\n

      This simplifies the process and enables more controlled, cleaner and more orderly production.<\/p>\n

      Reduced cleaning and greater plant availability<\/h4>\n

      Cleaning is an important factor in any liquid manufacturing installation.<\/p>\n

      In a traditional model, each finished-product tank involves an associated cleaning operation.<\/p>\n

      With post-addition, the need to clean large storage tanks for final product is reduced. Operations are concentrated on the concentrate reactor, the common lines and the system close to packaging.<\/p>\n

      The result:<\/p>\n

        \n
      • Less time<\/b> spent on cleaning.<\/li>\n
      • Lower consumption<\/b> associated with these operations.<\/li>\n
      • Greater availability<\/b> of the installation.<\/li>\n<\/ul>\n

        \u00a0\u00a0<\/p>\n

        When does it make sense to opt for post-addition?<\/h4>\n

        Post-addition is especially interesting in processes with:<\/p>\n

          \n
        • High production volumes.<\/li>\n
        • A large number of final SKUs.<\/li>\n
        • Frequent formula changes.<\/li>\n
        • The need to manufacture different batch sizes.<\/li>\n
        • Limited factory space.<\/li>\n<\/ul>\n

          \u00a0<\/p>\n

          Each application requires a specific study of the product, viscosity, rheological behaviour and formulation in order to define the best process architecture.<\/p>\n

          It is particularly common in the \ud835\uddf1\ud835\uddf2\ud835\ude01\ud835\uddf2\ud835\uddff\ud835\uddf4\ud835\uddf2\ud835\uddfb\ud835\ude01 \ud835\uddee\ud835\uddfb\ud835\uddf1 \ud835\uddfd\ud835\uddf2\ud835\uddff\ud835\ude00\ud835\uddfc\ud835\uddfb\ud835\uddee\ud835\uddf9 \ud835\uddf0\ud835\uddee\ud835\uddff\ud835\uddf2 \ud835\ude00\ud835\uddf2\ud835\uddf0\ud835\ude01\ud835\uddfc\ud835\uddff\ud835\ude00.<\/p>\n

          VK Post-addition: more flexibility, more efficiency, more future<\/h4>\n

          Post-addition is not just a new mixing technology. It is a new way of organising production.<\/p>\n

          Moving from manufacturing and storing large quantities of finished product to manufacturing on demand allows plants to be more flexible, take up less space and adapt better to a market with greater product variety.<\/p>\n

          With experience in agitation, in-line mixing, helical pumps (progressive cavity pumps) and complete mixing installations, VAK KIMSA develops global solutions to help industries evolve toward more efficient production processes.<\/p>\n
