Why air enters
Juice can pick up air at several operations
Crushing, pressing, filtration, pumping and mixing can expose juice to air. The correct intervention point depends on the actual line, not a generic flow diagram.
Mechanical processing creates interfaces where air can be entrained.
Transfer and mixing can add air through splashing, vortexing or suction leaks.
Open downstream steps can reintroduce oxygen after effective deaeration.
Line boundary
Measure beyond the deaerator outlet
The outlet value is useful, but the business result usually sits at heating, storage or filling. Define both points.
Juice data set
Information that changes the configuration
Do not copy a model from another juice line. Record the process conditions that create this duty.
Product
Composition & aroma
Clear or cloudy, pulp level, soluble solids, aroma sensitivity and foam tendency.
Duty
Flow & temperature
Operating range, production pattern, inlet temperature and allowable thermal change.
Acceptance
Oxygen & test point
Inlet DO, target value, instrument, sample method and downstream verification point.
Process trade-off
Removing air can also carry volatile aroma
Vacuum conditions and temperature must balance gas release with product quality. When aroma is sensitive, condenser or recovery scope and product testing deserve explicit review.
