Question: Which mechanical seal is better to use for flushing, single-acting or double-acting?
Answer: We strongly recommend a double-acting mechanical seal for high hygiene applications. Flushing (10 l/h) through the seal ensures that no bacteria can build up behind the seal. The seal is the most important part of the dynamic mixer because oxygen leads to bacterial growth. Water flushing is a mechanical barrier that provides a much higher level of hygiene. Many competitors offer a one-way action, but this is outdated technology.
П: What if the client would like to have more than one input or one output.
В: Our DLM/M-ECO standard is one input and one output. But as a rule, we can fulfil customer requests for connection types, sizes and positions. More inputs are not a problem, they just lead to a different version of the mixer.
П: INDAG's model is often smaller than a competitor's, why?
В: The INDAG design has proven itself well. We have sold or installed hundreds of these mixers for yoghurt or cheese + fruit. The machines are highly efficient. The big advantage of a smaller mixing chamber is that the customer wastes less product in the case of CIP/SIP cleaning. In addition, the space and weight requirements are lower.
П: Can the INDAG mixer damage the product?
В: Our DLM/M-ECO mixers are designed for the preparation of shear-sensitive fruit. In the case of special, very sensitive pieces of fruit, we have a special hook-shaped rotor. When using this shape, we usually use a mixer one size larger than with a standard paddle.
П: Do I need a frequency converter?
В: This is not required, but is highly recommended. Only in addition to a frequency converter is the full flexibility of a dynamic inline mixer ensured. The rotational speed and thus the energy input can be easily adjusted. Especially in the case of different recipes and different flow weights, an adjustable rotational speed has many advantages.
