Raw material receiving, washing and sorting
Check incoming onion cleanliness and defect level before washing. Raw material quality affects washing intensity, yield and flavor stability.
Onion processing line for paste, puree, sauce base and prepared seasoning ingredients, designed around peeling, odor management, crushing, cooking or sterilization and hygienic filling.



This onion line is planned for juice, puree, paste, extract or concentrate projects. The key engineering scope is strong washing, trimming, crushing, fiber/solids control, extraction or pulping, heat treatment and cleaning design.
The onion route should prioritize strong washing, solids handling, fiber control and the selection between juice, puree, extract or concentrate products.
Check incoming onion cleanliness and defect level before washing. Raw material quality affects washing intensity, yield and flavor stability.
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.
Refining or pulping controls particle size, removes coarse solids and stabilizes the downstream product route.
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.
Pasteurization or sterilization is selected according to pH, product texture, shelf-life target and packaging format.
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.
Different finished products lead to different equipment scope, utility demand, heat-treatment method and packaging logic.
Onion juice routes prioritize extraction yield, filtration and beverage stability.
Onion puree or paste production should define fiber level, texture and packaging route.
Onion extract or base production may require stronger solids handling and formulation control.
Onion concentrate routes add evaporation when higher solids products are required.
| Typical capacity | Industrial planning range depends on onion 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. |
Onion processing should account for peeling, volatile aroma compounds and product style. Onion juice, paste and sauce bases need different crushing, heating and odor-management strategies.
Onion outer skin and root ends must be removed before clean processing. Peeling method affects yield, labor, hygiene and waste volume.
Onion releases strong volatiles during cutting and crushing. Factory ventilation, enclosed conveyors and operator comfort should be included in layout planning.
Onion juice routes need extraction and filtration, while paste routes retain solids and may need cooking or blending. The RFQ should define the commercial product before equipment selection.
Heating can soften pungency and develop sweetness. The thermal route should match whether the final product is fresh onion juice, cooked sauce base or seasoning ingredient.
Onion skins and trims are light but bulky. Waste removal and cleaning access should be planned to prevent contamination and odor accumulation.
Confirm onion variety, peeling method, juice/paste/extract route, cooked or fresh flavor target, particle size, packaging, ventilation need and capacity.
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.
Each module should be selected according to raw material condition, target product route, capacity, cleaning requirement and final packaging plan.
Stronger washing is often required for root or aromatic raw materials carrying soil and surface contamination.
Crushing prepares the raw material for extraction, pulping or downstream solids handling.
A decanter can support separation, fiber control or clarification where the process route requires it.
Tubular heat treatment can be considered when puree, paste or fiber-containing products are involved.
CIP design is important for hygienic operation and cleaning of fiber-rich or strongly aromatic products.
These answers help separate a real process route from a simple equipment list 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.
Some upstream equipment can be shared, especially washing, sorting and part of the extraction section. The downstream route may change once the product becomes onion paste, onion puree, sauce base, seasoning base and aseptic onion 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.
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 peeling yield, odor control, particle size, cooking color, viscosity, cleaning difficulty and corrosion-resistant contact parts. Those factors change stainless steel contact area, pump type, heat exchanger style, tank volume, cleaning design and installation work.
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.
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.
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.
Onion raw material needs skin, root and defect removal before crushing. Strong odor, volatile compounds and sticky cooked solids affect plant ventilation, cleaning and operator comfort.
The route may include peeling, trimming, washing, crushing or chopping, cooking or blending, deaeration, heat treatment and filling.
The complete scope may include peeling and trimming section, washing system, crusher, pulper or blending tank, tubular sterilizer, filler and CIP. Confirm steam, power, compressed air, cooling water, drainage, CIP level and automation requirement before judging price.
| RFQ Item | Reference Information to Provide | Engineering Reason |
|---|---|---|
| Finished products | onion paste, onion puree, sauce base, seasoning base and aseptic onion ingredient | Different products may share the same front end but require different pulping, heat treatment, filling and storage logic. |
| Critical concern | peeling yield, odor control, particle size, cooking color, viscosity, cleaning difficulty and corrosion-resistant contact parts | This is usually where equipment sizing, material selection, cleaning design and quality risk become different from a generic line. |
| Capacity and season | Hourly intake, operating hours per day, harvest season or frozen raw material plan. | Capacity affects buffer tanks, utility peak load, staffing, front-end width and aseptic filler size. |
| Brix, pH, viscosity and particles | Use measured data when available. If not, mark values as preliminary planning references only. | These values decide pump type, heat exchanger style, deaeration, evaporation and filling behavior. |
| Packaging and shelf life | Aseptic drum, bag-in-bin, bottle, pouch, can, jar, frozen pack or chilled distribution. | Packaging changes sterilization, filling machine, SIP/CIP scope, logistics and finished product storage. |
