Reda DeAlcoholisation

The Reda Concentrator can also be used to DeAlcoholize wines, this is a fully automated unit.

The concentrator evaporates water at low temperature due to the low pressure (vacuum) vessel. During evaporation of wine, alcohol which is more volatile than water is the first to be extracted through the condenser. The result is a solution of water and alcohol that is separated into a tank. After this the water can be separated. Again with this unit a percentage of the wine can be treated and blended back into the tank.

Juice concentration occurs under forced vacuum where virtually pure water is evaporated at a temperature of 20-24OC. This is important to prevent 'cooking' of the fruit that occurs with 'flash' systems that are sold by other companies. The Reda Concentrator can work by recirculating the entire tank or by concentrating only a part, such as 20%. These Concentrators need only electric current to operate (they don't use fuel or water) and running costs are very low. Applications are varied for this type of unit: 1/ for harvests diluted by excess rain 2/ For hot areas where a slightly early harvest can occur to maintain a better balance of sugar, acidity and aromatics 3/ for good conditioned grapes where the sugar is generally low.

There are 5 models available from wineries processing 2,000-8,000lts to 100,000-200,000lts per day.
