GEA DICON® - not only a unit, it is a technology
The beverage industry faces continued demands to increase efficiency, while at the same time working to speed innovation cycles. This is particularly true for manufacturers of multi-component products, who look to benefit from production systems that are cost effective, flexible, and help to ensure reproducible processing. Such demands on the industry are exactly why we’ve developed the GEA DICON® technology for continuous in-line blending.
Here are the main points:
GEA DICON®-C
Features
This versatile technology doesn’t limit the number of components to be mixed, and can handle flow rates upwards of 1 l/h in the concentrate lines. Liquid flows measured by accurate flow meters are transmitted to the automatic system controller, which compares the measured values to the preselected mixing ratios, and actuates the controlling devices to ensure that mixing parameters precisely meet the preset values. Short-term control deviations are completely compensated. Deaerating and test vessels prevent air occlusions and potential related measuring errors. They also enable the system to do regular flow meter checks. Modulating valves and/or positive pumps with frequency converter are used as controlling devices. Following in-line blending the product can then be transferred to the GEA DICAR carbonator, which sets the CO2 content, and monitors, in-line, essential product criteria such as Brix value and conductivity. If required, the technology can also be configured to carry out automatic correction of, for example, Brix deviations, within the GEA DICON®-C system.

GEA DIVA
Features
The GEA DIVA system for alcohol reception and continuous in-line blending is designed for the reception of raw alcohol directly from tankers. The system accurately measures the quantity of alcohol – for precise weights & measures recording – and blends the alcohol with water to reduce the alcohol content to less than 76% volume, so as not to be subject to the ex-regulations in different areas (ATEX).
An air eliminator in the unit’s alcohol reception section separates any air that is also carried in the pipeline from the liquid stream. A pump then conveys the alcohol from the air eliminator, through a mass flow meter to the mixing point. The mass flow meter detects the alcohol stream, and the flow is set by means of a control valve to ensure the correct water and alcohol ratios for mixing. The desired alcohol and water ratio in the mixture is preset by the operator.
A regulatory-compliant density metering system mounted in the outlet of the GEA DIVA system measures the alcohol content of the alcohol/water mixture, and this value is passed to the controller, which makes any necessary adjustments to maintain an accurate ratio for the mixture. The system can keep the alcohol/water ratio to within ±0.05% volume of alcohol.
The controller calculates the water mass that is still to be dosed from the existing mass portion of water in the initial alcohol and the demanded mass portion of water in the mixture. Dosing deviations during the start are detected and compensated.
The system itself is designed to be mounted in a hazardous area, whereas the control unit is usually installed outside of the hazardous area.
