The material flows downwards through the center of the vessel by gravity whilst the high rotational speed of the agitator ensures mid-shear mixing in very short batch times. A distinctive factor about the Vitomix is the double ribbon screw which enables a transport capacity of up to eight times that of standard conical screw mixers. The result is a substantial improvement in mixing efficiency and a much more efficient and faster mixing process even at lower speeds. The design of the two conical screws creates a fluidized bed in the upper part of the mixer cone that is perfect for adding liquids. A liquid spraying system can be fitted through the hollow axle, providing flexibility in the location and the number of nozzles and lances you choose; without influencing mixing properties or spraying on metal parts. The Hosokawa Vitomix can be tailored for use in a wide variety of applications, these include:
  • Fast mixing of powders, pastes and slurries
  • Addition of liquids and fats without the use of lumpbreakers
  • Gentle mixing combined with mid shear mixing in one machine
  • Coating powders with powders
  • Granulating
  • Flavoring
  • Coloring
  • Heating / cooling

In an Active Freeze Dryer, the product is first frozen dynamically by moving it in a specially designed chamber. Whether the material to be dried starts off as a liquid, granular solid or paste, the forced motion inside the drying chamber ensures that it freezes in the form of free-flowing solid granules.

Once the product is fully frozen, a deep vacuum is applied and the sublimation starts. Heat applied to the vessel jacket is effectively distributed throughout the product due to the dynamic environment. The initially coarse, frozen granules gradually shrink as the ice structure connecting the frozen material sublimes, yielding a loose powder consisting of fine, dry particles.

As the solvent disappears, the product temperature starts to rise until it equals the jacket temperature. This marks the end of the drying process. Once the vacuum has been released, the chamber is opened and the powdered product can be discharged.

Typical applications include pharmaceuticals like antibiotics, proteins, collagens, APIs and electrolytes. This new technology has also proven its suitability to the freeze drying of special materials like nano-materials, polymers, ceramics, pigments, fillers, lime stone, catalysts, glass powder and salts.

TCCA – Compaction of Trichloroisocyanuric Acid

TCCA – Compaction of Trichloroisocyanuric Acid

Application:

Trichloroisocyanuric Acid is a disinfectant, algaecide and bactericide mainly for swimming pools and it is also used as a bleaching agent in the textile industry. It is widely used in civil sanitation for pools and spas, preventing and curing diseases in animal husbandry and fisheries, fruit and vegetable preservation, wastewater treatment, as an algaecide for recycled water in industry and air conditioning.For easier dosing and reduction of its odor it is typically sold as tablets or dust free granules.

Process:

The material contains chlorine which makes a wet handling very difficult (pH value 2.5 – 4) because of the corrosive behavior. Therefor the chemical is dried in the process and the fine powder will be compacted to granules in a dry process.

This dry process contains the compaction of the powder to so called flakes. In a several crushing steps process the flakes will end up in granules for example 5 – 15 or 10 – 30 mesh. Typically the parts in contact with the TCCA are made out of stainless steel. The change to a different granule size is quite easy and can be made by changing the screen opening in the screening machine.

Example:

Alpine Roller Compactor ARC MS 60 with 2 step size reduction and screening machine

  • Output 1800 kg/h = 4000 lb/h
  • Max. moisture content 0.5%wt H2O
  • Bulk density = 0.85 – 0.95 g/cm3
  • Size = 0.5 – 2 mm = 10-35 mesh
