DeAlcoTec - Dealcoholisation System Brochure

The product will be pre-heated by a plate heat exchanger downstream of the degassing section and runs down from the top to the bottom of the column. In counter current flow the alcohol of the product will be removed by exhaust vapors which is passing the column from the bottom to the top. The alcohol free product will be taken from the bottom outlet of the column and passes an evaporator to generate the required exhaust vapor out of it  to keep the dealcoholisation process running. The remaining liquid product, which contains no alcohol anymore will pumped and chilled to the next process step. The vapor which contains alcohol will be concentrated downstream by a rectification column and condensated in a chiller to saleable product. From the exhaust vapor aroma can be extracted in a specific recovery system and recycled to the product.
