Plum Processing Line
The EasyReal plum processing line delivers stable performance for both high-pulp and low-pulp products. We use food-grade stainless steel for all contact parts and follow modular design so you can adjust the line based on product type.
Each line starts with a plum washing and sorting unit, followed by a destoning pulper that separates pits and peels from the pulp. Then, based on the target product, the flow diverges:
● For juice, we include extraction, enzymatic treatment, clarification, and evaporation.
● For puree, we keep the pulp with minimal filtration and apply gentle heating.
● For jam or paste, we include blending tanks, sugar dissolvers, and vacuum cookers.
All thermal processes use precise PID temperature control. Our tube-in-tube sterilizers handle high-viscosity plum paste without overheating or fouling. Finally, products enter aseptic or hot filling lines.
EasyReal designs each line for easy cleaning, energy savings, and high uptime. Whether you need 500 kg/h or 20,000 kg/h output, our engineers can tailor the solution to fit your plant size, energy availability, and packaging format.
Fruit processors use EasyReal plum lines in multiple ways:
● Juice factories produce NFC and concentrate.
● Jam brands create sweet-spread products from clingstone or damson varieties.
● Puree suppliers export semi-finished pulp for baby food and dairy blends.
● Bakery chains use plum paste for mooncakes, tarts, and filled cookies.
We also support:
● Agri-cooperatives processing surplus fresh plums during harvest season.
● OEM exporters making bulk-packed 220L bag-in-drum products.
● Contract processors who serve multiple fruit clients on one flexible line.
Our plum lines adapt to multiple cultivars like red plum, yellow plum, greengage, or damson. Whether you're targeting local retail jars or large-scale bulk filling, EasyReal has case-proven designs.
To select the correct plum processing line, consider these key factors:
1. Output capacity:
● Small scale: 500–1000 kg/h
● Medium scale: 2–5 tons/h
● Industrial scale: 10 tons/h and above
2. Product type:
● For juice and concentrate: choose models with enzymatic treatment, centrifugal clarification, and falling-film evaporator.
● For puree and baby food: use mild pulping with minimal filtration and low-shear sterilizers.
● For jam or paste: select vacuum cookers, sugar mixers, and high-viscosity fillers.
3. Packaging form:
● Retail glass bottles or jars (200–1000 ml)
● Hot-fill plastic bottles
● 200L/220L aseptic bags in drums
● 1–5L foodservice bags
4. Raw material condition:
● Fresh plums
● IQF or frozen
● Pre-pitted pulp
Our sales engineers can simulate different flow paths for your product goals. We help you compare investment vs. yield, processing time vs. shelf life, and manual vs. automatic setup.
Here’s how the full line processes raw plums into final products:
Fresh Plums
→ Elevating Conveyor
→ Bubble Washer + Brush Washer
→ Sorting Conveyor
→ Destoning Pulper
→ Preheater
→ (optional) Enzyme Treatment Tank
→ (optional) Centrifugal Clarifier
→ (optional) Evaporator for Concentration
→ Sterilizer (tube-in-tube or tubular type)
→ Aseptic Filling or Hot Filling
→ Finished Product: Juice / Puree / Jam / Paste
We customize the chart depending on your output. For example, puree skips enzyme and clarification steps. Jam lines include a blending & sugar dissolving unit before vacuum cooking.
Let’s look at the core equipment that makes your plum line effective:
Plum Bubble Washer + Brush Washer
This unit lifts and soaks plums in a stainless-steel tank with circulating water. A bubble system gently agitates the fruit to remove dust and dirt. Then, rotary brushes scrub the surface and rinse with fresh water.
→ Helps remove pesticides and soft skins without damage.
→ Reduces labor and improves hygiene in first stage.
Plum Sorting Conveyor
A stainless-steel belt moves the washed plums under light or visual inspection. Operators remove spoiled or unripe fruits.
→ Ensures only high-quality fruit enters the pulping step.
→ Optional camera sorting available for full automation.
Plum Destoning Pulper
This machine uses a high-speed rotary sieve to separate pits from the flesh. The inner blade rotates against a mesh screen while pulp passes through.
→ Removes plum stones efficiently without crushing the kernel.
→ Yields smooth puree or juice base with minimal waste.
Enzyme Treatment Tank
For juice and concentrate, this tank adds food-grade enzymes to break down pectin and reduce viscosity.
→ Improves juice yield and reduces filtration load.
→ Fully jacketed tank with paddle mixer and temperature control.
Centrifugal Clarifier
This centrifuge separates suspended solids from juice after enzymatic breakdown.
→ Delivers crystal-clear plum juice.
→ Especially useful for NFC and clear concentrate lines.
Falling-Film Evaporator or Forced Evaporator
The evaporator concentrates juice into syrup or paste form. Juice enters thin film over heated tubes and water evaporates.
→ Uses low-temp vacuum evaporation for flavor preservation.
→ Energy-saving with heat reuse from previous effects.
Tube-in-Tube or Tubular Sterilizer
We use tubular type sterilizers for juice and tube-in-tube type sterilizers for viscous jam/paste/puree.
→ Maintains high product quality at 95–121°C.
→ Includes temp recorder, holding tubes, and backpressure valve.
→ Avoids fouling even with thick plum pulp.
Aseptic Filling Machine
This machine fills sterilized plum product into sterile bags inside drums or bins.
→ Works under cleanroom or sterile air flow conditions.
→ Available in single-head or double-head versions.
→ Suitable for export and long shelf life storage.
The EasyReal plum processing line handles a wide variety of plum cultivars and input conditions. Whether you receive red plums, yellow plums, greengages, or damsons, our system adjusts flow and filtration steps to match texture and sugar-acid balance.
You can feed:
● Fresh whole plums (with pits)
● Frozen or thawed plums
● Pre-pitted pulp from cold storage
● Overripe or bruised stock for paste
Each product target has a unique process path. For example:
● Juice lines emphasize clarification and enzyme breakdown for better yield.
● Puree lines skip clarification and keep the pulp fiber for spoonable texture.
● Jam or paste lines use vacuum cooking and sugar addition to achieve the right Brix and viscosity.
Flexibility also comes from packaging options. The same core line can switch between:
● 200 ml retail bottles
● 3 to 5L BIB bags
● 220L aseptic drums
We design the system to allow quick CIP cleaning, recipe switching, and production rerouting. That means you can run juice in the morning and paste in the afternoon.
If your supply changes by season or market demand, EasyReal’s modular design keeps your line running with high efficiency and low waste.
The plum processing line runs on a PLC + HMI smart control system, giving you full control and data visibility at every step.
The central touchscreen lets you:
● Set temperatures, speeds, and pressures for each unit
● Monitor flow rates and product holding times
● Track batch history and CIP cycles
● Trigger alarms for abnormal parameters
We use branded PLC controllers like Siemens with integrated HMI panels. For critical steps such as sterilization and aseptic filling, we add PID temperature control and back-pressure regulation to guarantee safety and product consistency.
For large-scale systems, you can also choose:
● Remote diagnostics and troubleshooting support
● Data logging and export for compliance reporting
● Recipe management modules to switch products easily
All systems are programmed by our in-house electrical engineers and tested during FAT before delivery(Factory Acceptance Test). You get a stable and easy-to-use platform that requires minimal training.
With EasyReal’s smart controls, you don’t need to guess what’s happening inside the pipes. You see it live, adjust instantly, and stay in control of every batch.
