CryoSurge on the Lyochrysalis and S3PulseInstruments, detection and the authority that acts

CryoSurge is read on a real machine: probes in the product, a control system that records every holder, and an authority that answers for every command.

01The Lyochrysalis research platform

The Lyochrysalis is Panacea Bio Chem’s lyophilisation research machine, built on a Virtis freeze-dryer: immersed product-temperature probes, one in each product holder; refrigeration with a high stage, a low stage and an interchange; a heat-transfer fluid (HTF) circuit with its pump and heater; vacuum instrumentation with an Inficon CDG025D capacitance gauge and a Barocel 600; and relays that S3Pulse reads back after every command.

How CryoSurge is read and acted on Three product holders inside the Lyochrysalis chamber, each with its own temperature probe feeding S3Pulse; the temperature sensor on the heat-transfer fluid pump outlet feeds S3Pulse too, and S3Pulse interprets the product and loop temperatures. S3Pulse sends every command through the Actuator Authority, which reads the relays back. The HTF pump pushes the heat-transfer fluid through the heater and on through the holders, circulating continuously; the heater is pulsed; refrigeration cools the fluid.vacuum: Inficon CDG025D · Barocel 600Lyochrysalis chamberHolder 1probeHolder 2probeHolder 3probeheat-transfer fluid, circulating continuouslyS3Pulsereads every holder's probereads the HTF loop sensorinterprets product and looprecords onset · peak · returnruns DCSN and DCSAActuator Authorityowner check · relay readbackheaterHTF pumpHTF temperature sensor on the pump outletHTF sensorrefrigerationHS · LS · IX
Schematic, not to scale. Each holder's own probe feeds S3Pulse, and so does the temperature sensor on the heat-transfer fluid (HTF) pump outlet; every command goes through the Actuator Authority and is read back at the relay; the HTF pump drives the fluid through the heater and on to the holders, and it keeps circulating while the heater is pulsed. HS, LS, IX: high stage, low stage, interchange of the refrigeration.

03Detection, holder by holder

S3Pulse follows each holder’s probe on its own. When a probe that has been cooling through the supercooled zone rebounds sharply, S3Pulse records that holder’s CryoSurge: its onset, its natural peak and its return. The record is kept per formulation, so a later run of the same formulation knows where to expect its CryoSurge — and DCSN can fire its nucleation burst ahead of it.

04Authority: every command accounted for

In S3Pulse no controller switches a relay directly. Every heater, pump, valve and refrigeration command passes the Actuator Authority, which checks which controller owns that device in the current phase, executes the command and confirms it by reading the relay back; a supervisor independent of the controllers watches the process whether a controller is running, stopped or restarting.

05Heat without overshoot

During DCSA the heater is pulsed while the HTF pump runs continuously, so heat reaches the holders through a circulating fluid rather than in surges. S3Pulse’s record proves the command and the relay readback: the pump on through the warming, the hold and the final freeze, the heater pulsing on its own.
