Mixers - VTB manufactures horizontal designs such as double ribbon mixer (BWM), paddle (DWPM), ploughshare (PSM) and kettle mixers (VKM). All variants are also built as a double-shell mixer for heating and / or cooling. The heating can be done by means of steam, hot water or other suitable liquid or hot air. Cooling can be done over cold water or brine and chiller. The variants paddle / ploughshare / kettle are equipped with chopper heads and are suitable for drawing up liquids.
Ploughshare mixers (PSM) also known as white flour mixers, are primarily designed to mix powder as quickly as possible, it comes physically to a high input of energy, agglomerates are broken up and crushed. Normal mixing times are between 3 - 8 minutes. Double ribbon mixers (BWM) with double helix mix the products much more gently, herbs are not destroyed, for example. The mixing times are usually 5 - 15 minutes.
The paddle mixer and double-shaft paddle mixer (DWPM) are technically the link between ploughshare and double ribbon mixer.
Kettle mixers are technically another variant and use a different operating principle. Kettle mixers combine the advantages of different mixing technologies. With kettle mixers (VKM)
for example, mixtures can be spread as quickly as ploughshare (PSM), but with less mechanical input. Another advantage of our kettle mixers (VKM) is the drawing up of liquids.
The three-bladed mixing tool accelerates this to mix in a trumpet-shaped circulation. This product movement results in shortest mixing times, combined with outstanding mixing quality and enables targeted granule formation. So that the accelerated and upward flowing material is deflected in the optimal mixing area, the boiler is conically constructed in the upper area. The screw plug of the three-bladed mixing tool is designed as a displacer. This prevents mixing material from staying and collecting in the area of low centrifugal forces. The three-bladed mixing tool moves very close to the bottom of the tank, so that an excellent mixing result can be achieved here. At the same time results from the low installation height of the mixing tool optimal and fast emptying. A separately driven cutter head is used to open up any existing agglomerates, as well as for uniform moistening and granulation. The liquid is added either gravimetrically or with a pump directly into the area of action of the cutter head to ensure the best possible distribution. The optional wet sieve on the emptying creates a completely homogeneous size distribution of the granules.
