Plum Puree and Juice Processing Line for Pulp, Jam Base and Aseptic Products

Industrial scope for Plum puree and pulp processing.

This plum line is planned for puree, pulp, juice base and aseptic bulk product projects. The core engineering scope is pretreatment, pulping, fiber control, deaeration, viscous-product heat treatment and hygienic filling.

• Suitable for fresh or prepared plum raw material after ripeness, fiber and defect evaluation.
• Typical products include puree, pulp, juice base and aseptic bulk product.
• Core process modules include peeling/destoning where required, pulping, refining, deaeration and tubular sterilization.
• Packaging can be configured for aseptic bag-in-drum, bin, bottle, pouch or intermediate bulk storage.

Plum process route and engineering logic.

The plum line is usually planned around peeling or destoning, pulp texture control, vacuum deaeration, viscous product sterilization and bulk aseptic filling.

Raw material receiving, washing and sorting

Check plum variety, ripeness and defect level before production. This stage affects pulp yield, fiber content and downstream destoning or refining stability.

Trimming, crushing, juicing, pulping or extraction

Trim the raw material to remove unwanted peel, core or damaged parts according to the target product route. Proper trimming reduces off-flavor, excess fiber and unnecessary downstream solids.

Separation, refining, deaeration or homogenization

Pulping and refining control fiber, skin residue and puree smoothness. Screen size should be matched to whether the project targets plum puree, pulp or beverage base.

Optional concentration, blending or standardization

At this stage the product can be adjusted for Brix, solids, acidity, recipe balance or ingredient formulation. This is where the process is matched to the commercial product specification.

Sterilization, pasteurization or filling preparation

Heat treatment should be selected according to viscosity, particle level and shelf-life requirement. Tubular or other appropriate systems may be preferred for plum puree-type products.

Packaging, cooling and storage

The final filling route should match the sales channel and storage plan, such as aseptic bag, drum, bottle, can, jar or pouch. Packaging choice also affects the overall thermal process and quotation scope.

Plum product routes and scope.

Different finished products lead to different equipment scope, utility demand, heat-treatment method and packaging logic.

Puree

Plum puree production focuses on screen selection, fiber control, deaeration and viscous-product sterilization.

Pulp

Plum pulp routes keep more fruit body and should define target mouthfeel, particle level and packaging format.

Juice Base

Plum juice base routes may require dilution, blending, filtration or homogenization depending on the beverage application.

Aseptic Bulk Product

Aseptic plum product is suitable for industrial storage and export when long shelf life is required.

Critical engineering points.

• Plum varieties differ in fiber, stone or seed structure and pulp yield, so pretreatment cannot be treated as a generic fruit step.
• Puree viscosity influences pump selection, pipeline pressure drop and the choice of heat exchanger type.
• Air incorporation during pulping can accelerate color and flavor loss, so deaeration is often important.
• If the project targets aseptic bulk packaging, sterilization and sanitary filling should be planned together from the beginning.

Reference scope for discussion.

Plum line decisions: pit removal, skin pigment, acidity and jam or puree route.

Plum projects are different from peach projects because skin pigment, acidity, tannin/astringency and pit handling strongly affect the finished product route. The line should be designed for juice, puree or jam base rather than copied from a peach puree template.

Pit removal and fruit integrity

Plum pits must be removed reliably without excessive pulp loss. Fruit firmness and pit adhesion vary by variety, so the pitting method should be matched to incoming fruit condition and expected capacity.

Skin color and astringency

Plum skin contributes color and flavor but can also bring astringency or coarse particles. The project should define whether skin color is desired in puree or jam, or whether a smoother lighter product is required.

Acidity and sugar balance

Plum products often require careful flavor balance for juice, puree or jam bases. Blending, sugar addition and concentration scope should be discussed if the line is intended for finished retail products instead of bulk pulp.

Jam and sauce preparation

A plum line may feed jam, filling or fruit preparation production. In that case, heating, mixing, concentration and particle retention should be considered together with basic pulping.

Sterilization and filling

Plum puree with skin particles may require a heat exchanger suited for suspended solids. Packaging can be aseptic bulk, jars, pouches or downstream ingredient tanks, each with different hygienic requirements.

RFQ parameters to confirm

Confirm plum variety, pit size, skin-in or skin-out target, juice/puree/jam route, acidity or sugar adjustment, particle tolerance, packaging format and seasonal production hours.

For a useful quotation, include the raw material condition, target product route, expected capacity, packaging format, available utilities and any quality requirement that affects equipment selection.

Equipment modules and their role in the line.

Each module should be selected according to raw material condition, target product route, capacity, cleaning requirement and final packaging plan.

Peeling / Destoning Machine

This section prepares plum raw material before pulping and directly affects yield, fiber level and downstream refining stability.

Double Stage Pulping Machine

The pulping section controls texture and removes coarse solids when producing plum puree or pulp.

Vacuum Deaerator

Deaeration reduces air in the product stream and helps protect plum color and flavor before heat treatment.

Tubular Sterilizer

Tubular heat treatment is commonly considered for viscous plum products where low-viscosity plate systems may not be ideal.

Aseptic Filling Machine

Aseptic filling supports long shelf life for bulk plum puree or pulp storage and export.

This section is written for RFQ preparation. Values are reference only until raw material tests, product specifications and final layout review confirm the process route.

Raw material behavior

Plum variety, ripeness and stone adhesion determine the difficulty of destoning and pulping. Peel and color compounds also affect product appearance.

Process route logic

The route normally includes washing, sorting, destoning, pulping or pressing, refining, deaeration, sterilization, optional concentration and filling.

Factory planning boundary

The complete scope may include washing system, destoner, pulper, vacuum deaerator, tubular sterilizer, aseptic filler and CIP. Confirm steam, power, compressed air, cooling water, drainage, CIP level and automation requirement before judging price.
