Fruit Pulp Paddle Finisher
The Fruit Pulp Paddle Finisher from Shanghai EasyReal Machinery Co., Ltd. is built around the principle of centrifugal pulp refining. A horizontal shaft drives helical paddles inside a stainless-steel cylinder lined with a precisely machined screen. As fruit pulp flows through, the paddles press and scrape it against the screen, allowing juice and fine pulp to pass while rejecting larger fibers and seeds toward the discharge end.
Each unit is easy to clean, with spray balls and quick-release assemblies for fast cleaning. The shaft runs on food-grade mechanical seals to prevent product leakage. Operators control all parameters via an HMI panel linked to a Siemens PLC.
The machine’s compact footprint and sanitary piping layout make it ideal for both stand-alone operation and integration within complete fruit processing lines such as mango puree, tomato paste, and apple sauce plants. Its energy-efficient drive and wear-resistant screen design help extend service life and lower operating costs through reduced downtime and spare-part consumption.
The Fruit Pulper and Refiner Machine is widely used across fruit juice, puree, jam, and baby food production lines. Its gentle refining action protects the product’s cell structure and color, making it suitable for sensitive fruits such as strawberry, kiwifruit, and guava.
Typical applications include:
• Tomato processing lines for removing skins and seeds after crushing.
• Mango, papaya, and banana puree refining for smooth dessert bases.
• Apple and pear processing to obtain clear juice or pulp for sauce.
• Citrus and berry processing to produce high-quality pulp for yogurt mixes and beverage blends.
Processors value its ability to maintain consistent output viscosity and minimize oxidation. The machine supports quick screen changes to adapt mesh size for different fruit types or end products, allowing rapid SKU switchovers during peak seasons. This versatility translates into higher plant utilization and fewer customer complaints from texture inconsistency or seed residue.
Efficient pulp refining demands a properly balanced upstream and downstream line. Raw materials arrive with varying fiber and seed content; if fed without uniform pre-crushing, screen loading rises and throughput drops. Therefore, EasyReal recommends pairing the Fruit Pulp Paddle Finisher with its dedicated crushing, pre-heating, and de-aeration modules. These systems stabilize feed temperature and viscosity before refining, reducing mechanical stress on the screen and bearings.
Viscous or pectin-rich products (such as apricot or guava puree) may require tube-in tube heat exchangers to maintain fluidity and prevent gelling inside the machine. Hygiene is another critical factor: Remove residual pulp and seeds after each run, eliminating microbial risks and cross-flavor contamination.
By matching line components for temperature, flow, and shear balance, EasyReal helps clients achieve steady yields and longer screen service intervals. The result is a fully integrated fruit processing system that combines high capacity with precision and food safety.
Selecting the right Paddle Finisher starts with defining product range and daily volume. Batch capacity and mesh size determine refining speed and pulp quality. For instance, fine-mesh screens (0.5–0.8 mm) suit juice production, while coarser meshes (1.0–2.05 mm) fit puree or sauce applications.
Key factors to consider:
1. Capacity requirement: Typical industrial models handle 2–30 tons per hour depending on fruit type and feed consistency.
2. Screen design: Single vs double-stage finishers for different refining levels.
3. Rotor speed: Variable frequency drive allows adjustment between 300–1200 rpmthe speed of the motor to match viscosity.
4. Ease of maintenance: Quick-open end covers and balanced shafts simplify daily inspection.
5. Material: All contact parts in SS316L for corrosion resistance and sanitary performance.
EasyReal’s engineering team offers pilot-scale testing to determine optimal mesh and speed before scale-up. This approach reduces trial time on-site and ensures the final line matches your raw material mix and product viscosity. Each project comes with a customized layout, utility plan, and startup support for the first production season.
Below is a typical flow for industrial pulp extraction and refining lines using the Fruit Pulp Paddle Finisher:
1. Fruit Receiving and Sorting → remove damaged pieces and foreign matter.
2. Washing and Inspection → ensure surface cleanliness.
3. Crushing / Pre-heating → Crushed Fruit and deactivate enzymes.
4. Primary Pulper → initial separation of pulp from peel and seeds.
5. Secondary Fruit Pulp Paddle Finisher → fine refining through paddle-driven screening.
6. Vacuum Deaeration → remove air bubbles to prevent oxidation.
7. Pasteurization / UHT Treatment → thermal stabilization for long shelf life.
8. Aseptic Filling / Hot-Fill Station → ready for storage or downstream use.
Branch paths exist for different product styles: smooth puree lines use double finishers in series, while chunky sauce lines retain coarser screens to preserve mouthfeel. By balancing these paths, operators can switch between juice, nectar, and puree production within one plant layout.
A full Fruit Pulper and Refiner Machine line integrates several processing modules that work together for consistent yield and product stability. Each component plays a specific role in optimizing texture, minimizing waste, and ensuring sanitary operation.
1. Fruit Crusher
Before the fruit enters the paddle finisher, the crusher breaks it into uniform particles. This step prevents screen overload and ensures smooth feeding. EasyReal’s industrial crushers feature adjustable blades and a heavy-duty drive, capable of handling mango, apple, tomato, and other fibrous fruits with minimal maintenance.
2. Pre-Heater / Enzyme Deactivator
This tubular heat exchanger gently heats the pulp to 60–90 °C to loosen cell walls and deactivate enzymes like pectin methylesterase. It reduces viscosity variation and stabilizes flavor. Temperature and residence time are precisely controlled through Siemens PLC setpoints for repeatable results.
3. Fruit Pulp Paddle Finisher
The heart of the refining line — it separates seeds, peels, and coarse fibers using high-speed paddles and perforated stainless-steel screens. Rotor geometry and pitch angle are optimized for maximum throughput with minimal shear. The outlet pulp shows uniform texture and natural gloss, ready for further concentration or pasteurization.
4. Juice Collection Tank & Transfer Pump
After refining, juice and fine pulp fall into a sealed collection tank. A sanitary pump transfers the product to the next stage. All wetted parts are SS316L, with tri-clamp connections for easy disassembly and CIP cleaning.
5. Vacuum Deaerator
Entrained air can lead to oxidation and foaming during pasteurization. The vacuum deaerator removes air at controlled pressure levels (−0.08 MPa typical), preserving bright color and aroma. The deaerator’s inline design allows continuous operation with minimal footprint.
6. Aseptic Filler
The refined and deaerated pulp can be packed in aseptic bags or drums for long-term storage. EasyReal’s aseptic filler includes sterile barriers, steam sterilization loops, and temperature-controlled filling heads to ensure food safety and high productivity.
Each subsystem is modular and skid-mounted for quick installation and maintenance. Together, they form a fully automated processing line delivering stable °Brix, excellent mouthfeel, and high energy efficiency.
The Fruit Pulp Paddle Finisher line supports multiple input materials and output product styles, giving processors flexibility throughout the year.
Input forms:
• Fresh fruit (mango, tomato, apple, pear, guava, etc.)
• Frozen pulp or aseptic concentrate
• Mixtures or reconstituted blends for beverage bases
Output options:
• Smooth purée for baby food, jams, and dessert bases
• Clear juice or nectar after fine filtration
• Coarse pulp for sauce, bakery filling, or ice-cream ripple
• High-Brix concentrate for storage and export
Thanks to the modular screen and rotor system, operators can change mesh size or finisher stage configuration in less than 20 minutes. Seasonal changes in fruit quality — from early-season softness to late-season hardness — can be managed by adjusting rotor speed and screen pressure setpoints via the PLC interface. This adaptability allows consistent yield and texture even under variable raw-material conditions.
EasyReal’s engineering team assists processors in defining recipes, CIP cycles, and operational parameters tailored to each product type. As a result, the same line can handle diverse SKUs while keeping cleaning and downtime costs low.
Automation is central to EasyReal’s design philosophy. The Paddle Finisher line is managed by a Siemens PLC with an intuitive HMI interface that gives operators full visibility into process variables — rotor speed, feed flow, screen differential pressure, and motor load.
Core control features include:
• Recipe management for each fruit type (tomato, mango, apple, etc.)
• Trend charts and historical data export for quality auditing
• Alarm interlocks and safety shutdowns for overload or pressure spikes
• Batch ID tagging and export reports for traceability
• Remote monitoring and diagnostics support via Ethernet
Automated CIP cycles are pre-programmed to wash all contact surfaces, including rotor chamber, screens, and piping, ensuring fast turnaround between production batches. The system’s integration with upstream and downstream units (crusher, heater, deaerator, filler) allows centralized command — one operator can oversee the entire refining section from a single screen.
This digital architecture improves batch repeatability, reduces operator error, and ensures long-term reliability. It also supports predictive maintenance through trend monitoring, helping clients avoid unplanned downtime and protect equipment investment.
