Definitions

  • Dialkyl dicarbonates are used in the beverage industry for the cold sterilization of non-alcoholic carbonated or still fruit juice drinks, fruit juices, wines, non-alcoholic wines, ciders, ice teas and other beverages.
  • This technology of beverage stabilization has a number of advantages.

  • Persistent preservatives such as benzoate or benzoic acid or sorbate or sorbic acid also have the advantage, especially in the absence of any taste impairments.
  • Compared to a cold aseptic filling especially the very much lower investment costs in plant technology are known as an advantage in the use of dialkyldicarbonates.
  • dialkyl dicarbonates has the special property of hydrolyzing in contact with corresponding (aqueous) beverages in the derived alcohols and carbon dioxide.

  • the Dosierang the dialkyl dicarbonates is carried out according to the prior art under high pressure in front of the nozzle, usually well> 20 bar. This pressure is necessary to ensure adequate atomization and uniform distribution of the pure dialkyl dicarbonates in the beverage stream.
  • the nozzle must be heated in the rule, since the beverage filling temperature may be below the melting point of dialkyl dicarbonates, and thus could crystallize the pure dialkyldicarbonates on or in the nozzle.
  • the dosage is discontinuous. In the sense of a uniform distribution of dialkyl dicarbonates in the drink, this is not optimal.

  • An embodiment of the mixing chamber is, for example, a preferably about 0.5 to 100 ml small container in which the solvent (mixture) and dialkyl dicarbonate are introduced, for example by compressed air.
  • the chamber is advantageously shaped such that already takes place during the entry or injection of the two components, a good mixing.

This can be achieved, for example, in that a correspondingly configured steel spring presses on a sealing plate with a corresponding pressure within the nozzle. Therefore, if the dialkyl dicarbonate solution is pressed into the arrangement, more and more nozzles are opened successively, thus allowing the uniform introduction of increasing or decreasing quantities of liquid.
