Clarification & finishing · Stage 06
Build a clear juice finishing sequence from enzymatic treatment, separation and filtration, with clarity and stability defined before equipment is selected.
THE PROCESS DUTY
Clarification is a sequence, not a single tank or filter. Apple juice may be treated with a product-specific enzyme, separated by settling, a horizontal decanter centrifuge or another method, then filtered to the required clarity. The sequence and duty depend on the juice, the target appearance and the stability requirement. Clear juice is not the same as NFC, and clarification alone does not establish shelf stability.
IN THE LINE
The equipment is only useful when its feed and discharge are defined. These adjacent duties are the first interfaces to review.
WORKING PRINCIPLE
The explanation starts with the material and the process, not a catalogue description.
Clear means more than 'not cloudy'. Specify the measurement method, sample conditions and acceptable appearance after storage. A bench trial with the actual juice is more useful than a catalogue clarity claim. The target determines whether settling, centrifugation, filtration or a combination is appropriate.
Pectinases and other enzymes can change how suspended material separates. Dose, temperature, time, pH and enzyme preparation must be evaluated with the actual juice. An enzyme that works in one trial may behave differently with another apple lot. Food-grade status and approval for the intended use belong in the project review.
A separator removes bulk solids; a filter polishes the juice to a finer clarity. Placing a fine filter before bulk separation can blind it quickly. The sequence should remove the easy solids first and protect the final filtration step.
Clarification creates a solids or retentate stream and retains juice in the equipment. Both affect yield and waste handling. Include them in the material balance and define how retained material is recovered or discharged.
WHERE IT FITS
WHAT TO WATCH
CONFIGURATION OPTIONS
These are the choices that change the equipment scope. The approved datasheet fixes the final selection.
Manual or automatic addition with a defined mixing and residence step.
Settling, centrifugation or another bulk-solids removal method.
A polishing filter selected around the solids load and target clarity.
Tanks, pumps and closed transfer to protect the clarified juice.
CIP or manual cleaning for tanks, separators and filter housings.
SELECTION FACTORS
Bring these points to the equipment discussion. They are more useful than a single throughput number.
The measurement method and storage conditions define what 'clear' means.
Pressed juice from different presses carries different solids.
A bench trial should establish dose, time and temperature.
Retained juice and separated solids need a defined destination.
SPECIFICATIONS
No catalogue model or performance figure is shown until the configuration is approved. The final datasheet fixes these items.

TECHNICAL FAQ
If your question depends on the fruit, product or site, include the conditions in the enquiry rather than relying on a general answer.
Send a project enquiryNo. Clear describes appearance; NFC describes the absence of concentration. Clear NFC juice is possible, and clear concentrate also exists. Choose clarity and concentration as separate decisions.
It depends on the enzyme, dose, temperature, pH and juice. There is no universal hold time. Establish the treatment window with a bench or pilot trial using representative juice, then confirm it in the selected equipment.
Some juices can be clarified by settling, centrifugation and filtration alone, but the result depends on the solids and pectin content. Enzymatic treatment is one option, not a mandatory step. The right sequence should be tested.
Clarity immediately after filtration does not guarantee stability. Protein, polyphenol, pectin or other interactions can develop during storage. The evaluation should include the intended storage conditions and a defined stability test.
