Lecture 10: The processes of concentration and temperature control of
raw materials, semi-finished products
Plan:
1. The modern alcohol production technology
2. Equipment for the process of alcohol distillation
3. Scientific support ethanol production process
4. The quality characteristics of modern production of jelly sweets with
herbal fillers
5. Technology of wine from the sea buckthorn
Heat and mass transfer processes: drying, cooking, distillation, roasting,
baking and others.
One example is the processing of grain and potatoes on alcohol for the
same type of technology on the stage:
□ preparation of raw materials for processing; - Cooking of starchy raw
materials; - Saccharification of starch raw materials;
□ cultivation of yeast; - Fermentation of saccharified mass; - Distilling the
mash; - Rectification of alcohol.
□ Workflow on bragorektifikatsionnyh plants differentiated in stages that
carry out sequentially in separate columns:
□ in the mash (mash distillation to produce a mash distillate and tap
stillage "in the form of waste production);
□ in Epuration (separation of mash distillate or alcohol - raw and
concentration of impurities and the head of the selection with a fraction of the
brain of ethanol - a byproduct of the production);
□ in distillation (alcohol concentration and pasteurization and isolation
during the concentration of impurities in the intermediate alcohol as a fusel
fraction);
□ in fusel or extractive - distillation (fusel oil concentrating and isolating it
as a marketable by-product);
□ column final cleaning (additional cleaning rectified alcohol with a
branch to re-distillation of alcohol fractions with impurities);
□ column to separate the alcohol from the overhead (top fraction from the
selection and concentration of methanol, aldehydes, esters).
Isolation of alcohol from the mash and purification alcohol - crude
(distillation) from the impurities produced in bragorektifikatsionnom vacuum
apparatus which comprises three columns: bragoepyuratsionnoy, Epuration and
distillation.
