IN
ASEPTIC PROCESSING

2. INTRODUCTION
Aseptic processing denotes the filling commercially sterilized and cooled product into
pre-sterilized containers under aseptic conditions and sealing in an atmosphere free of
micro-organisms
UHT PROCESS = (130–150 °C ) for 1–2 sec

3. BASIC REQUIREMENTS OF ASEPTIC PROCESSING
EQUIPMENTS
1.
• Sanitary design
2.
• Capable of being sterilized (steam,
chemical, water, media)
3.
• Free from cracks, crevices, dead
spots
4.
• Capable of maintaining sterile state
5.
• Capable of being operated at
constant mode
6.
• Confirm to design , state and
federal regulatory codes

4. ASEPTIC PROCESSING METHODOLOGY
Sterilization of the
product
Sterilization of
packaging material
Sterilization of
aseptic
installations
Maintaining
sterility of the total
system
Production of
hermatic packages

5. ASEPTIC PROCESSING EQUIPMENTS
• PRIMARY COMPONENETS
• BLENDING TANK
• METERING PUMP
• HEAT EXCHANGERS
• HOLDING TUBE
• AIR OPERATED VALVES
• CONTROL SYSTEM
• ASEPTIC SURGE TANK

6. STERILIZATION OF ASEPTIC MACHINES
• H202 spray (disinfectant)
• Hot air= 330- 350˚C , 30 min
• Water vapour = presterilization
• Low acid ( superheated steam), high acid (wet steam)
PACKAGING MACHINES
• Pressurized superheated steam= 130-135˚C
• Pressure= 2 Bar
• Polyalcohol mixture= 170˚C (rinsing)
FILLING LINERS & FILLERS
• Incineration= 300-350˚C
• Cartridge filters= pressurized steam
• Blown clean sterile air
AIR FILTERS

7. BLENDING TANK AND BALANCE SURGE
1
• Completely suitable for CIP& SIP
2
• Crevices and dead leg free contact surfaces
3
• Bottom Magnetic Mixer
4
• 100% Drainability
5
• Top or bottom Entry Mixing System with
Double Mechanical Seals
6
• Process Automaon with Piping and
Transferring Systems
7
• Electropolished from inside <0.5 Ra
finish
8
• Sterile Micron Filtraon System
9
• Aspetic Sampling facility

8. BALANCE SURGE

9. TIMING PUMP
Delivers constant and accurate flow
Creates strong suction to draw the
product
Fed continuously to produce a constant
flow
RECIPROCATING PISTON PUMP
Suitable for product containing distinct
food pieces with zero slip

10. HEAT EXCHANGERS
PARAMOUNT METHDS INCLUDES:
PLATE HEAT
EXCHANGER
DIRECT
STEAM
SCRAPPED
SURFACE
HEAT
EXCHANGER
TUBULAR
HEAT
EXCHANGER
MICROWAVE
HEATING
OHMIC
HEATING
DIRECT STEAM: INJECTION/INFUSION
 Reduces the sterilization temperature very quickly and
removes water from the product
 Burnt flavor & color loss is minimal
 Steam is injected in continuous flow

11. PLATE HEAT EXCHANGER OHMIC HEATING

12. CONTINUOUS HOLDING TUBES
The product is being holded for
specific temperature and time
Inactivate bacteria & enzymes
Burnt odor, caramelization , vitamin
and color loss

13. DEAERATOR
Removes
undesirable
air before
final
sterilization
and cooling
operations
Reduce
fouling &
Prevent
foaming
Maintains
constant
filling
conditions &
specific
volume

14. HOMOGENIZER
disintegrate or
finely distribute
the particles
particle size
reduction using
shear force
Maintains
uniformity &
stability
Improve shelf life,
quality & taste
Pressure range
500- 1000psig

15. FILTERS
