2. Sterilizer Specifications
• Processing Vessel Inside Diameter: 1500mm.
• Holding Capacity Six Pallets
• Maximum Working Pressure, 5 Bar
• Maximum Working Temperature, 205C
• Executed In ANSI 304L Stainless Steel
• Electrical And Mechanical Safety Lock On Door
4. Operating Principle
• Combination of water sprays with
direct steam injection provide heat
transfer
• Direct steam injection into the
chamber
• Circulated water distributed by spray
nozzle's create a homogeneous
mixture of steam, air and water
• Heat transfer by the steam/water
mixture continuously cascades across
the containers reducing film coefficient
• Air overpressure for counter balance
above saturated steam setpoint
5. LOG-TECTM

6. • Controller
• Executes automatic
sequence of operation
• Controls analog and
digital valves
• Maintains local operator
and management
passwords
• Provide program
override options
• Host computer
• Process calculation

LOG-TECTM Process Management
7. • Controller self test before process start-up
– Analog input values are scanned for validity prior to the start of
every process
– If an analog value is out of range the operator is verified and the
process log records the failure
• Advanced “what if” logic
– Program routines that work with analog and digital logic that
validate the process in real time
Controller Operation
8. Critical Process Alarms
• Critical inputs are continuously monitored
– Temperature
• Temperature tracking
• Deviation correction
• High temperature alarm
• RTD comparison check
– Pressure
• Profile pressure
• Alarm pressure
– Flow
• Low flow
• Critical flow
– Level
• Alarm level HI
• Alarm level LOW
– Steam, Air, Water Manifold Pressure
– Door Position
– Motor Overloads
11. • Vacuum Breaker
• The vacuum breaker for prevent
retort vessel in vacuum condition.
• The vacuum may cause of
collapse retort vessel.
Safety equipments
12. • Zero pressure switch & Lockpin
• The zero pressure switch
mechanism use for prevent open
retort door under pressure. This
mechanism will latch door lock at
all times. If retort vessel under
pressure the lock pin unable to
unlock.
Safety equipments
13. • Door Switch & Instrument Air
supply valve
• The door safety switch with
disconnect instrument air to
control system at unlock status.
All of control and process valve
will be not function at door open.
Safety equipments
15. • Temperature sensor
• The temperature is RTD’s
PT-100 located at back side
of retort. This is double
element sensor. In cause
first element failed during
process, the second
element will take control till
finish process.
Processing Equipments
17. • Pressure Transmitter
• The pressure transmitter
measure vessel pressure
and send to control system.
Processing Equipments
18. • Level Transmitter
• The level transmitter measure
water level in side vessel and
send to control suystem.
Processing Equipments
19. • Water Flow Meter
• The flow meter measure water
circulation during process.
Processing Equipments
20. •Plate Heat Exchanger
•The plate heat exchanger use for
indirect cooling. Indirect cooling
prevented contaminate from
cooling water to product.
•Indirect cooling also prevent
thermal shock during change step
from Cook to Cooling
Processing Equipments
21. • Nozzle Spray
• The nozzle spray use for
spray water cover the
basket. The water made
event temperature
distribution during process.
Processing Equipments
22. • Water circulations pump
• The water circulation
pump use for create
water circulation and
flow through nozzle
spray.
Processing Equipments
23. • Water Filter/Strainer
• The water filter/strainer use for
prevent big particle block at
nozzle.
Processing Equipments
27. Fill To Level
• Retort Door Closes, Mechanical And Electrical Interlocks Are
Activated
• Fill Valve Opens, Controller Fills Vessel To Preset Level
• Controller Will Scan For Maximum Time To Achieve Level
Full Condition
34. Cooling
• Cooling Water Is Proportionally Injected Into The Heat
Exchanger Based On A Pre-programmed Cooling Rate
• Air And Vent Control Valves Follow Pre-programmed
Overpressure Setpoint Routines
39. End Cycle
• Drain Valve Opens, Controller Waits For Low Level
Condition
• Residual Pressure Is Released
• Return drum to home position
• Controller Disables Mechanical And Electrical Interlocks
