Plum Puree and Juice Processing Line for Pulp, Jam Base and Aseptic Products
Plum processing line for puree, pulp, juice base, jam base and aseptic bulk products, with route planning for destoning, peel control, acidity, color retention and heat treatment.
Line scope
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.
Process route
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.
02
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.
03
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.
04
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.
05
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.
06
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.
Finished product routes
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.
Processing challenges
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.
Typical parameters
Reference scope for discussion.
| Typical capacity | Industrial planning range depends on plum supply, working shift and final product route. |
| Finished products | Juice, puree, pulp, concentrate, sauce, beverage base or aseptic bulk product depending on project scope. |
| Key process decisions | Raw material condition, texture target, heat treatment method, packaging format and utility conditions. |
| Packaging options | Aseptic bag, drum, bottle, jar, pouch, can or bulk tank depending on shelf-life target. |
| Automation & cleaning | PLC + HMI operation, sanitary piping and CIP/SIP options can be discussed. |
Material-specific engineering
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.

Key equipment
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.
FAQ
Plum Puree and Juice Processing Line for Pulp, Jam Base and Aseptic Products quotation questions.
These answers help separate a real process route from a simple equipment list before quotation.
What information is needed before quotation?
Provide raw material form, finished product, expected hourly capacity, operating season, Brix or solids data, pH if available, viscosity or texture target, fiber, seed or particle limits, package format, shelf-life target and utility conditions. If some values are not final, mark them as preliminary references. The quotation can then show a realistic process route instead of a generic machine list.
Can one line make several finished products?
Some upstream equipment can be shared, especially washing, sorting and part of the extraction section. The downstream route may change once the product becomes plum puree, plum pulp, juice base, jam base and aseptic plum ingredient. Different products can require different pulper screens, heat treatment, evaporation, filling or storage conditions. For multi-product planning, list the main product first and treat other products as optional routes during quotation.
Which equipment normally drives the cost?
The cost is usually driven by capacity, product viscosity, required particle control, heat-treatment method, evaporation need, aseptic filling, automation level and utility scope. For this line, the sensitive items are stone removal, peel residue, tart flavor balance, color stability, viscosity and screen clogging. Those factors change stainless steel contact area, pump type, heat exchanger style, tank volume, cleaning design and installation work.
Are the parameters on this page final specifications?
No. Any capacity, Brix, heat-treatment or utility value shown on the website should be treated as a planning reference only. Final specifications must be confirmed with raw material samples, buyer product standards, local sanitary requirements and factory layout. This is especially important when viscosity, seed content, fiber, acidity or heat sensitivity changes by variety and season.
How should the factory layout be prepared?
Share the building size, floor drain position, available height, raw material receiving direction, packaging area, utility room, boiler or steam source, cooling water, compressed air and desired automation level. A practical layout should connect receiving, preparation, processing, filling, CIP and storage with enough operator access and cleaning space. Layout data also helps avoid quoting equipment that cannot be installed efficiently.
