Dumek's new exclusive Dual Planetary mixing system improves heat exchange levels beyond those of any standard system. The important contra-rotating effect in the core section - which guarantees the "shear" on the processed mass which is typical of all coaxial systems - combines with the simultaneous movement of two satellites along the circumference of the vessel; this allows for even heat distribution which improves the results of the finished product. The scrapers are made in different shapes and materials and the settings can be varied so they either touch or simply graze the inner wall of the vessel.
In the Dumoturbo range, the homogenizing unit - comprising a turbine with rotor and stator - is fitted at the bottom of the vessel and not at the top; the advantages are clear to see:
The internal layout provides for effective treatment of "difficult" products such as masks and toothpastes thanks to the shorter and dimensioned drive shaft which guarantees transmission of more power and makes the homogenizing unit more sturdy.
The turbine is simple to access and its components can be removed which means maintenance work is always quick and easy. These features raise quality standards and prevent the risk of product pollution caused by stagnating residues. Furthermore, the average working life of the mechanical seals has been increased 3 or 4-fold thanks to the decrease in stress on the short drive shaft and the presence of the lubrication circuit which guarantees long-term performance.
The minimum processing quantities are now lower which boosts versatility levels.
Dumek certainly proves to be the ideal choice when one’s attention turns to efficient use of resources, time and raw materials.
Heating times, for instance, have been remarkably reduced due to the insulation jacket that facilitates heat flows inside the autoclave; the interspace serpentine encourages even heat distribution over the entire volume being processed.
This results in outstanding energy savings.
It is also possible to use the same fluid for both the heating and the cooling cycle thanks to the special thermoregulation unit featuring a closed circuit combined with a Chiller station. This prevents any processing fluids from leaking into the environment, hence safeguarding the same and guaranteeing ethically commendable savings.
The entire Dumoturbo series can be controlled using the user-friendly Dumek C.D.I. System which replaces the classic electronic control panels with membrane keyboard and requires just a few simple operations.
The System operates under the Windows environment and uses a common PC to manage all the phases of the processing cycles, memorizing an endless number of formulas which can then be viewed on graphic reports. The data can easily be transferred onto any USB pen drive. It can also be connected to a serial port printer to record the parameters at preset intervals.
Each Dumoturbo model protects the quality of the finished products, even during the ejection phase, which may be performed as follows:
The autoclave can also perform CIP washes with the application of tank washer heads that operate under high pressure.
Dumoturbo's range of products can satisfy every possible requirement in terms of capacity and accessories. Simply choose the right one for your business.
