This Concept Map, created with IHMC CmapTools, has information related to: Vacuum circuit, Vacuum Circuit Works with Vacuum pump (M311, V329, V331, TC331), Vacuum pump (M311, V329, V331, TC331) Purpose Create vacuum in flash vessel, Safety Relief valve (SV347) Purpose Protect flash vessel from overpressure, Regulatory (TSL347) Purpose Monitors the “coldest spot in flash vessel”, Key valves (V311, V312, V316, V334) Controls V311, V312, V316, V334is on/off solenoid activated based on step sequence, Vacuum pump (M311, V329, V331, TC331) Controls M311 runs at fixed output. Air is supplied to suction side of M311 at a modulated rate due to V331’smodulation for TC331’stemperature control V329 is on/off solenoid activated based on M311running, Safety Relief valve (SV347) Controls Thermo-Mechanical valve, Regulatory (TSL347) Controls TSL347 is monitored directly in the Legal Box for control of Flow Diversion Valves , depends on year of new generation in regards to Aseptic operation, Vacuum Circuit Works with Safety Relief valve (SV347), Key valves (V311, V312, V316, V334) Functionality Connect vacuum circuit to process flow during sterilization Help ease the transition into vacuum during cooling steps after sterilization, Vacuum Circuit Works with Regulatory (TSL347), Safety Relief valve (SV347) Functionality During sterilization, the flash vessel is operating under positive pressure as the temperature is ~290 °F. SV347 is there to protect the vessel in case temperatures exceed safety relief valve opening rate. Typically higher that ~301 to 305 °F, Key valves (V311, V312, V316, V334) Purpose Sterilize vacuum circuit, Vacuum circuit proper cooling operation, Regulatory (TSL347) Functionality Assures the entire flash vessel, the dome, complete vacuum circuit and all piping leading to TSL347 position, are all above minimum the ESL and/or Aseptic temperature guard, Vacuum pump (M311, V329, V331, TC331) Functionality M311 and the condenser cooling circuit, work in concert to achieve proper level of vacuum/cooling effect to flash excess steam from the product, therefore cooling product back down to roughly the preheat temperature V329 is water supply to liquid ring vacuum pump, M311, Vacuum Circuit Works with Key valves (V311, V312, V316, V334)
