Dealcoholators
REDA has perfected the technique of fractional distillation at very low temperatures for alcohol recovery from the following applications:
Partial wine Dealcoholization
This new dealcoholization system is designed to be used for wines dealcholisation through low temperature distillation. With this innovative technique only part of the wine comes processed (10/20% of the mass) while the remaining will be not touched.
A great advantage for preservation of wine quality.
The treatment foresees a fast “cold distillation” of the wine at +15°C with extraction of an evaporate mixture with 50°/60° Alcohol.
Aromas recovery system will be selected in case of aromatic wines process.
Advantages
The very low process temperature and the great flexibility of REDA dealcholizer allow to get final wine with -1°/-2° Alcohol very well balanced, fresh and aromatic.
The best results are obtained in absolute terms by intervening at the end of wine fermentation thus allowing it to find immediately a perfect balance and not to be disturbed anymore.
Finally, in case of raining season before grapes harvest, the unit can work as a classic low temperature concentrator for the self-enrichments of must always through under vacuum evaporation at +18°C/+22°C.
Natural extract alcohol Recovery / Concentration:
Thanks to the great experience gained in dealcoholation wine application, REDA has perfected the technique of fractional distillation at very low temperatures for the separation and recovery of the water/alcohol used in the production process of natural extracts, flavors, essences (from herbs, plants, flowers, leaves, roots, seeds, etc.).
Starting from the infusions or from hydro-alcoholic solutions used in extraction processes (with gradations even up to 98% alcohol), it is possible to concentrate the basic product (through cold evaporation) or separate solutions fully recovering alcohol for reuse in new processes.
The rapidity of the evaporation process, the very low temperatures applied and the reliability of the system, allow the concentration of the extract and the total recovery of the alcohol up to the last drop in total safety (according to ATEX rules) with continuous process or per batch.
The REDA system also allows the recovery of alcohol without loss of aromatic fractions.
The advantages of this technique are:
- Very low processing temperatures (no organoleptic alterations in the product).
- Protection of the aromas.
- Recovery of alcohol in a single step.
- Concentration of the product.
- Greater operational flexibility.
- Fully automatic operation.
The production range of our cold dealcoholizators varies from 25 to 800 liters/hour (with distilled at 50/60° alcohol).
