Industrial food mixer

The world's rapidly growing demand for food requires fast and cost effective methods of production. Industrial food mixers, as amixon® manufactures them, are important components to produce products hygienically and quickly. Industrial food mixers and powder mixers for various raw materials are important parts of the industrial food production. 

amixon® appliances are beared and driven only above the mixing chamber. No shaft passage is in direct contact with the material being mixed. This design is generally considered to be extremely hygienic and extremely low in maintenance, as the gasket must only seal against the gas atmosphere. In the case of the amixon® mixing technology, the sealing is carried out as a multi-layer lip seal. The lip is designed such that it rests on a ceramic sleeve and can be serviced and replaced without disassembling the gear box and motor. In addition to the low-maintenance design, the required downtime is reduced to a minimum. The hygienic lip seal is permanently gas- and water-tight and also suitable for vacuum and overpressure operation. 

Without a proper mixing plant, many production sites could hardly achieve the required quality and quantity of goods to be produced. amixon® mixing systems are used wherever different types of solids and liquids are mixed together and result in a new homogeneous product. The products thus produced come partly as finished products directly to the market or serve as premixes for new products.

These premixes are mostly added to a further production step in an additional mixing system for industrial food. This way, another new product is created. Often several mixing plants with an industrial food mixer are operated parallel or serial to realize economical multi-step processes. Depending on the design, the industrial food mixers are mounted on a horizontal plane, or vertically above each other within the system.

Due to their vertical design, the amixon® industrial food mixer is suitable for a vertical assembly within the mixing plant. This has the advantage that the products do not require additional support. Obeying the rules of gravity, they flow from top to bottom and can be supplied to the respective mixing plants without further aids. Another advantage of such a vertical installation is the cleaning of the mixing equipment, which can generally be done from top to bottom.

As a special service, amixon® offers test centres in many countries around the world, where the equipment for the mixing of industrial food can be tested on site. amixon® industrial food mixers serve for different products and processes, such as:

  • Baby food from dry milk derivatives, micronutrients, vitamins, stabilizers, etc.
  • Dry soups made from dried, ground fruit, spices etc.
  • Baking mixtures where only the addition of water is necessary
  • Baking agents, which the baker merely need to add flour, fat, milk or water
  • Decor-salts, Decor-sugar or Decor-spices, whose particles are all covered with hard fat.
  • Dessert products, that can be dissolved by adding water
  • Ice cream powder
  • Vitamin effervescent tablets
  • Nutritional supplements in tablet or powder form - Iodization of salt
  • Flavouring of coffee, tea or tobacco products

agglomeration

Agglomeration, granulation and grain enlargement
Adhesion and agglomeration of particles to roundish fragments, scabs, prills or pellets. Inter-particular bridging can occur through melt adhesion, reaction, crystallisation, dipoles or hardening.
Compared to finely dispersed materials, grain-enlarged materials flow better, are better suspendable, soluble, sinkable and pressable.
Moreover, agglomerated materials are less at risk of segregation. Grain agglomerations with high density are often called granulates, pellets, prills or scabs.
“Agglomerates” usually means grain agglomerations with large porosity, low density and good solubility. amixon® can realise gentle agglomeration up to build-up granulation with high energy input.

dispersing

Mixing / Deagglomerating is also random and results from the flowing and swirling of the mixture at high velocity. This operation is combined with high energy input. Primary particles, which have a tendency towards agglomeration or aggregation in smaller grain sizes, can be de-agglomerated by rubbing and crushing. In practice, the deagglomeration takes place by shearing, impact loading and friction (cutting rotors, HighShearBlades, dissolver, milling machines).
amixon® has patented smizers and rotor-stators.
The achievable mixing quality increases with increasing disintegration of the individual components.
The mixing quality describes the equal distribution/ homogeneity of the components. amixon® guarantees technically ideal mixing quality, which cannot be improved in practice!

mixing

Spreading of one or several components within another component, with all components differing in at least one property (colour, chemical composition, particle shape, particle size, ...)
Distributive mixing means the distribution or adsorption of one in/ beside another component.
Dispersive mixing is random and results from the flowing and swirling of the mix.

drying

Separation of adhesive liquids during mixing.
Depending on the type of energy input, a distinction is made between infrared drying, contact drying, convection drying and friction drying.
Vacuum excitation lowers the boiling point, which promotes vaporisation or sublimation. Chemical reactions in the reactor can be promoted through pressure, temperature and mechanical energy input.
amixon® can realise ideal reaction control and drying.

coating

Coating is a special method of grain enlargement.
Primary particles or granulates are encapsulated by a different material like a film.
The coating can be a micro-fine powder, a liquid or a solidified melt. Coating can be used for protecting, rounding off, inerting or hydrophobising of sensitive bulk materials.
amixon® can realise gentle coating up to mechanical alloying.
