This document summarizes a seminar on inplant training presented by Kayande Sandip Vasanrao. It describes the processes used at an alcohol manufacturing plant with 100 KLPD of molasses-based and 60 KLPD of grain-based distillery units. It outlines the key raw materials of rice, wheat, corn or barley, the storage of grains in silos, and the main production processes of milling and mashing, liquefaction, fermentation, and distillation to produce extra neutral alcohol, rectified spirit, and CO2. It provides details on the equipment used at each stage and the conversions that occur.

1. SEMINAR ON
INPLANT TRAING
PRESENTED BY
KAYANDE SANDIP VASANTRAO
Rg. No. NAY09FT16B

2. INTRODUCATION
Alcohol manufacturing industry.
Having 100 KLPD molasses based and 60 KLPD grain
based distillery unit.
Located at Dharmabad district Nanded. Near railway
line.
Produces Extra neutral alcohol, rectified spirit, CO2,
electricity.

3. RAW MATERIAL
Rice
 wheat, rice, corn, barley, sorghum, oats and
tubers as potato, cassava and sweat potato
Sr. No. Constituent Range ( % )
1 Starch 60-75
2 Moisture 8-12
3 Protein 6-12
4 Fat 3-6
5 Ash 1-5
6 sugars 1-3

4. Storage
Grain storage silo (750 MT)

5. PROCESS
MILLING & MASHING SECTION
LIQUEFACTION SECTION
FERMENTATION SECTION
DISTILLATION SECTION

6. MILLING & MASHING SECTION
Milling
 Grains are hammer milled to convert them in to flour
form.
 Elina engineering system Pune
 7 MT/Hr capacities.
 At the end of this step, the process results in GRAIN
STARCH.
Mashing
 In the mashing step, the grain starch is converted to
grain sugar.
 The grain meal is mixed with pure water and cooked. . .
At the end of this step, the process results in GRAIN
SUGAR.

7. LIQUEFACTION SECTION
 Alcohol production process is a conversion
process in which the polysaccharide of starch is
converted to monosaccharide by means of
enzymes & then into alcohol by microbial yeast.
C6H10O5 + H20 = C6H12O6
Starch Glucose

8. FERMENTATION SECTION
 Fermentation is the biochemical processes in
which carbohydrate are oxidized to alcohol,
carbon dioxide and other compound by the
action of certain micro-organism.

9. DISTILLATION SECTION
 Wash to ENA
 Degasifying column.
 Analyzer column.
 Pre-rectifier Column (C-411) and Pre-rectifier Stripper
Column.
 Extractive Distillation Column.
 Rectifier cum Exhaust Column.
 Fusel Oil Concentration Column.
 Simmering Column.
