Sterilization of spices, tea, cocoa, curry mixtures and cereal derivatives in the amixon® vacuum dryer
amixon® vacuum mix dryers/reactors can effectively sterilize natural products.
The industrial use of spices, herbs and nutrients usually requires that the substances are ground beforehand. Before milling, it must be ensured that spices, tea, cocoa and cereals are clean, i.e. free of foreign particles. The term cleanliness is microbiological hygiene is also meant in particular.
Natural goods may be contaminated with undesirable germs. These microorganisms are to be inactivated by thermal-pneumatic effects. Heating, wetting, drying and cooling are carried out in the amixon® sterile reactor. Processing in the amixon® apparatus can reduce the bacterial count by several orders of magnitude.
An effective method for germ reduction is the incorporation of hot water vapor. The spices, tea, cocoa, cereals are placed in a pressure-resistant, heated mixing chamber. They are mixed gently and slowly. First, the mixing chamber is under vacuum, then sterilized steam is injected at several points at the same time. A gauge pressure is built up in the mixing chamber.
The thermal energy of the water steam is released by condensation on the surface of the particles. Water has an extremely high enthalpy of evaporation. At the moment of condensation, a big amount of thermal energy is transferred to the spices very fast. The surface of the particles heats up and the germs on the surface are killed.
amixon® - sterile mixers facilitate success in a special way:
The heating of all machine parts in contact with the product ensures that the water vapor only condenses on the spice.
The gentle way of mixing ensures that the particle structure is preserved
When the disinfection target has been reached, the moisture introduced must be removed from the spice. Then the spice must be cooled. Both are done at the same time by vacuuming of the mixing chamber. In general, the germ contamination is reduced by several magnitudes of ten.
We cordially invite you to make trials in our excellently equipped amixon® test center. We are sure to provide you with valuable knowledge about mixing and mixing technology. A guided tour of the plant will show you the highlights of hygienic apparatus engineering.
