MasterRecipe: sim-filter-dry-m1

Filter-dryer isolation on sim-cell/filter-dryer-1. Use this recipe as the filter-dryer single-unit end-to-end demo. It walks the full isolation sequence from pre-batch vacuum-decay integrity check through cake build, wash, dry to endpoint, and discharge.

Where to find it

HMI endpoint → Batch Execution → + New → select sim-filter-dry-m1.

What you see when it runs

Element	Meaning
Procedure	Running from batch start
Phase cascade	Six phases execute in order; the longest is vacuum-dry, whose duration depends on how fast the simulated moisture sensor reaches target
Trends	Pressure, cake level, filtrate flow, and moisture each have a distinct shape — together they tell the story of a complete filter-dry cycle

Procedure

#	Step	Phase template	Description
1	vacuum-decay-test	fd-vacuum-decay-test	Apply vacuum and verify no leaks before production
2	filter-charge	filter-charge	Feed slurry and build filter cake under vacuum
3	smooth-cake	smooth-cake	Level cake surface with gentle agitation
4	filter-wash	filter-wash	Wash solvent through cake to displace impurities
5	vacuum-dry	vacuum-dry	Dry cake under vacuum with jacket heating to moisture endpoint
6	filter-discharge	filter-discharge	Break vacuum and discharge dry product

How it works

Each phase drives the filter-dryer through one stage of the isolation sequence:

1. vacuum-decay-test is an integrity gate — a pressure rise above max_rise parks the batch in Held on COMMAND('Hold').
2. filter-charge opens the feed, pulls slurry under vacuum, and builds cake to target_cake_height.
3. smooth-cake runs the smoother/agitator at low speed to even the cake surface before washing.
4. filter-wash loops through wash_cycles of wash solvent passes, checking filtrate permeability between cycles.
5. vacuum-dry pulls vacuum, heats the jacket, and holds until the moisture sensor reaches target_moisture (or max_dry_time fires as a safety backstop).
6. filter-discharge stops the vacuum pump, opens the vent, runs the agitator to break up the cake, and holds for the discharge time.

Try it

1. HMI endpoint → Batch Execution → + New → sim-filter-dry-m1 → Start
2. Expand the procedural tree and watch the six phases activate in turn
3. Open Data endpoint → Trends and chart all four key PVs (pressure_sensor.PV, cake_level_sensor.PV, moisture_sensor.PV, filtrate_flow_sensor.PV) on one view to see the distinct shape of each phase
