plants that process dry materials, water is reluctant to tolerate. Water or
high humidity in the ambient air can negatively influence the powder quality;
especially if bulk materials are hygroscopic. Quality assurance goes out of
control when microbiological processes are unintentionally triggered in the mix
that contaminate the powder and ambient air.
In this respect, the following applies almost in general: companies that process and mix powdery goods want to avoid the open appearance of water. In this respect, they will look for ways to clean the mixers as dry as possible. In some cases, cleaning can even be dispensed with altogether,
Depending on the industry, product group, degree of contamination and
of production, there are graduated cleaning regimes.

The bulk mixer shown on the right is exemplary for particularly hygienic powder mixtures. Carbohydrates, fats, vitamins and minerals are combined in powder form. Such a composition is physiologically optimally utilizable. The final products are easily digestible, long-lasting and very tasty. The powder mixture is dissolved in water like an instant drink. The nutrient density is particularly high but balanced. It allows a whole food diet without solid ingredients. The liquid can be drunk or given by tube.
The same powder mixer is also used to produce tablet masses, vitamin preparations, and food supplements. A formulation change takes place after almost every batch. ComDisc® tools achieve excellent residual discharging down to a few grams. This saves a lot of raw material. Almost all input materials are converted into saleable goods. There is hardly any waste. In this respect, very little washing water is required. Wet cleaning and drying are automatic.
By way of example, this also involves the following items:
and ComDisc® ensure good residual discharge. This means that (almost) all the
mix is utilized right from the start and a lot of washing water is saved. Other
aspects relate to the design of the inspection doors and their seals, OmgaSeal®
seals particularly close to the product - technically free of dead space, the
type and design of the shaft seals, lip seals glide on ceramic shaft coatings -
they work optionally with or without gas flushing, the type and design of the
dead space-free discharge valve, DosiFlap® can save vertical installation space
and replace valves, the operating mode and design of the dust filtration during
filling and emptying of the mixer, the type of drying and disposal of the moist
vapors, ... and much more
In the amixon® pilot plant we have good conditions to optimize your mixing processes and cleaning regimes. Optionally, we will demonstrate various wet cleaning concepts to you.
After wet cleaning, the washing water must flow out completely. Drying of the mixer is particularly fast when the mixer is cleaned with hot water. Due to the high heat capacity of water (more than 8 times that of steel) and the good heat conduction of steel, the mixer heats up spontaneously. This heat energy is used to evaporate the residual water. It is crucial that the resulting water vapour is safely discharged. This can be accelerated by feeding in warm air. It is recommended to open the inspection doors in the final phase of drying.
