Whole fruit and extracted juice need different front ends
A whole-fruit supply needs reception, washing, inspection and an opening operation that separates the shell from collected seed-pulp. A finisher receives material after that opening step. Sending intact fruit to a pulp-finishing assembly combines two duties that the equipment selection needs to keep separate.
If prepared juice is purchased, record what separation has already been completed. The remaining line may need liquid buffering, product treatment and filling rather than a second fruit-preparation section. Check representative incoming samples against the finished-ingredient requirement.
Agree what seed-free means for the buyer
The specification should distinguish intact seeds, broken seed fragments, shell specks and suspended pulp. Removing seeds does not define juice texture or soluble solids. Write down the sampling method and the permitted inclusions before discussing a screen size.
Use the same fruit lot and operating interval to compare recovered product and reject streams. A higher recovered flow may carry more unwanted material; recovery and the agreed product specification should be evaluated together. A general machine-family rating is not a confirmed passion fruit output.
| Decision | Selection basis |
|---|---|
| Seed condition | Intact seeds, fragments and the agreed detection method |
| Pulp texture | Suspended material and the required consistency |
| Separation trial | Representative feed, selected screens, output and rejects |
Match transfer and treatment to the finished liquid
Buffer volume and transfer pumps follow liquid flow, viscosity, solids and the next process inlet. Air entry at collection or transfer should be addressed before selecting a vacuum deaerator. Deaeration and evaporation have different purposes and should not be substituted for one another.
The thermal system and packaging route depend on the product specification and storage plan. Include the product inlet conditions and the package interface in the enquiry. The presence of a thermal skid or an aseptic filler alone does not establish a finished shelf life.
In practice
Questions about this stage
Does seed-free juice require the smallest available screen?
Not automatically. The screen is evaluated with actual feed, mechanical action and the required pulp content. Seed fragments and product recovery must be checked alongside texture.
