SUGAR PLANT AUTOMATION
ITS BENIFITS
BY

?
WHY THERE IS NEED FOR
SUGAR PLANT AUTOMATION ?
AGEC
4
REASONS
THERE ARE MANY BENEFITS WHICH CAN BE QUALIFIED
AFTER AUTOMATION OF SUGAR PLANT.
AGEC
5
There will be considerable reduction in Steam
cane, resulting in savings of Bagasse / Increase
in export power in cogeneration power plant by
the way of controlling steam to evaporators /
pans.
AGEC
6
IMPROVEMENT IN RBHR AS A RESULT OF REDUCTION IN
LOSS OF SUCROSE,

• Due to..
• Auto Lime Feeding
• Optimum Juice Temperature
• Regulating Vacuum for cake formation

AGEC
7

• Regulating Juice level in Evaporator
• Regulating steam / Vapour in Evaporator
• for uniform brix
• Regulating fan feed according to
• conductivity
• Maintaining uniform / optimum melt brix
• and condition of molasses.

8
There will be substantial reduction in man power
resulting in better and effective utilization of
man power.
AGEC
9
There are many benefits resulting from Sugar
Plant Automation which could not be quantified in
terms of savings, but would help in improvement
of plant performance.
AGEC
10
Reduced mill extraction would improve due to fine
and continuos control of mill / carrier load /
speed
AGEC
11
Crushing rate would become more uniform
continuous resulting in smooth operation of
plants.
AGEC
12
This would also result in reduction of down time
of mills other crushing equipments eventually
reduction of losses / man power.
AGEC
13
The Distributed Control System is Fed with
enormous amount of data regarding plant
operation. The data stored can be retrieved and
used for analysis regarding equipment / plant
performance.
AGEC
14
Automation of Sugar Plant will open flood gates
to acquire latest technologies /
trends Examples 1. Automatic Generation of
Reports 2. Remote Monitoring of Plant
Performance .
AGEC
15
The entire plant can be Automated OR Plant can
be Automated Section Wise
AGEC
16
DIFFERENCE SECTIONS FOR AUTOMATION

• Mills Preparatory Devices
• Juice Section
• Liming Sulphitation
• Clarification / Filter

AGEC
17

• Evaporators
• Pans
• Crystallisers pugmills Centrifugal
• Molasses Tanks

18

the last compartment
AGEC
33
CONTINUOS PAN MOLASSES CONTROL Massecuite flow to
the second compartment controlled with respect to
brix of massecuite in second and third compartment
AGEC
34
CONTINUOS PAN HOT WATER CONTROL Hot water inlet
to the ninth compartment is controlled with
respect to massecuite brix in the last
compartment
AGEC
35
BATCH PAN STEAM CONTROL Steam inlet to the pan is
controlled with respect to Vapour pressure
buildup in the pan
AGEC
36
BATCH PAN WATER CONTROL Water inlet to the pan is
controlled with respect to massecuite brix
AGEC
37
BATCH PAN FEED CONTROL Syrup / Massecuite inlet
to the pan is controlled with respect to
massecuite brix
AGEC
