Tetra Aldose® Aseptic in-line dosing - 1

Tetra Aldose® Aseptic in-line dosing Application Aseptic dosing of true solutions and suspensions containing particles smaller than 0.22 microns into aseptic systems. Examples of ingredient(s) that are suitable for aseptic dosing by a Tetra Aldose unit include: Enzymes, vitamins, aromas, flavourings, colourings and salt solutions, i.e. products not suitable for sterilisation by heat. The Tetra Aldose can also be used to achieve a sweeter taste in unsweetened milk products. The Tetra Aldose is fully automatic and can serve one or several fillers as well as an aseptic tank. Working principle The ingredient(s) to be dosed is stored in the tank on the unit. This ingredient(s) is pumped through pre-filter to remove larger particles, then through a sterile filter to remove bacteria and spores and then continuously dosed under aseptic conditions into the main flow. The ingredient(s) to be dosed is pumped by a positive displacement pump with speed control for accurate dosing. A flow transmitter controls the amount to be dosed and an aseptic valve cluster control the start and stop of dosing. The ingredient(s) is mixed into the main flow by a Tetra Aline in-line mixer. The Tetra Aldose unit can be connected at various stages to an aseptic process; downstream the steriliser in a UHT plant, upstream an Aseptic tank. The filter and entire pipe work, up to the dosing valve, are pre-sterilised before production by steam at 121°C for 30 minutes. After sterilisation the unit is cooled down with air. After production a CIP (Cleaning In Place) is performed. The Tetra Aldose is equipped with an internal automatic CIP. A CIP sequence normally contains both caustic and acid cleaning. The dosing process, pre-sterilisation and CIP are supervised from the control panel. The Tetra Aldose control system is prepared for connection as a slave unit to a central control system, or other modules such as Tetra Alsafe or filling machine.
