Automatic beer dealcoholization plant with gentle vacuum stripping process made by API Schmidt made this plant in the year 2002 the capacity 50 hl/h low alcohol beer / hour. Extracted alcohol aroma will be injected back to the low alcohol content beer and thus the original aroma of the beer can be recovered.
Non-Alcoholic Beer Production Plant Schmidt SIGMATEC 50 hl/h.
Automatic dealcoholization plant with CO2 carbonization unit (Diesel) and blending control unit to produce non-alcoholic beer from continuous vacuum rectification process. API Schmidt-Bretten GmbH & CO KG made this plant in the year 2002 the capacity 50 hl/h non alcohol beer / hour. Control PLC is Siemens Panel PC, which touch screen must be replaced. All parts in contact with the product, vapor and vapor condense manufactured in stainless steel. Original documentation and PLC programs copied in digital format. Equipment is in very good condition.

The beer taken from normal brewing process is preheated from 0 C in plate heat exchanger to the necessary dealcoholization temperature of 43 0C and comes to a deaerator. Here, the carbon dioxide being obtrusive for dealcoholization is removed from the beer. Now the CO2-free beer is reaching the stripper section of the rectification column and flows to the sump of the column against upcoming vapor. Here, an intensive distilling mass transfer takes place while the alcohol is enriched in the steam phase.The pressure in the column is 100-mbar abs. and due to that the temperature in the whole plant is max. 46 – 48 0C.From the sump of the column the beer comes to an evaporator in order to gain the necessary energy from the product itself to maintain the rectification.
After that the dealcoholization beer is recooled: first in a plate heat exchanger against incoming beer and then in a cooling section to the final storage temperature. The vapors, which are coming out of the product, are going counter current against the liquid to the head of the column.When the alcohol vapors are reaching the head of the column the alcohol content is between 70 – 75 % by volume and is converted to the liquid phase in the subsequent condenser.
In the Aroma Recovery Unit aroma components are recovered and redirected into the wine/beer. The alcohol rich vapors are condensed, cooled to a low temperature and stored in a tank in the form of industrial alcohol, which is a saleable product, which can be marketed immediately. Alcohol aroma will be injected back to the dealcoholization beer and thus the original aroma of the beer can be recovered. After this beer is carbonated in carbonization unit and pumped to storage tanks for filling.
