b'In-Line MixersHow to Use In-Line MixersRecirculation Method This is the most common way of using an In-Line mixer, providing a higher degree of homogenisation and particle size reduction. Here product is drawn from the bottom of the vessel, processed through the high shear rotor/stator workhead and passed back into the top of the vessel.In small vessels this will ensure adequate in-tank movement but in larger vessels an auxiliary in-tank mixer or agitator will be required.Additional fluid ingredients can be fed into the workhead and uniformly mixed before entering the vessel.Where quality assurance (QA) demands a set number of passes through the rotor/stator workhead, product can be passed back and forth between two separate vessels.Single Pass Method There are basically three types of operations forwhich single pass processing can be used:Continuous Blending Ingredients are metered into the mixer or a manifold just prior to the rotor/stator workhead. This ensures that products that react together are mixed immediately on contact. This method is ideal for continuous liquid/liquid blending and for products where aeration must be avoided, e.g. detergents.Series Processing In cases where a higher degree of homogenisation or comminution is required than can be obtained by a single pass through the In-Line mixer, it is possible to achieve the required results by using two or more machines in series. Premix Method The ingredients are coarsely premixed in a holding vessel with a Silverson Batch mixer, Ultramix or a simple agitator. A single pass through the In-Line mixer will then ensure an agglomerate-free homogeneous product.All the product must pass through the In-Line mixers rotor/stator workhead as by-passing is impossible.37 High Speed High Shear Mixers'
