ZNJ-25 Combined Rice Mill (Infeed 1,300–1,600; Output 800–1,000 kg/h)

The ZNJ-25 Combined Rice Mill is a high-capacity integrated rice processing system built on the proven ZNJ-15 platform. Engineered to deliver 800–1,000 kg/h of finished white rice, it handles the full milling sequence from raw paddy in one compact station — without requiring additional floor space compared to the ZNJ-15.

Key Features:

  • Capacity: 800–1,000 kg/h finished rice output (~20 tons/day)
  • All-in-one process: cleaning, de-stoning, husking, gravity separation, whitening, grading
  • Compact footprint: 3.7 × 1.6 × 3.4 m — same floor space as ZNJ-15
  • Higher throughput achieved without increasing main power consumption
  • Ideal for commercial rice mills, cooperatives, and medium-scale agricultural processing operations
 Technical Document
Overview
  • Removes large and fine impurities plus stones using a 56-type cylinder cleaner with integrated drawer-type destoner

  • Achieves high-efficiency husking with an 8-inch gearless paddy husker — designed for higher output with reduced grain stress

  • Splits paddy from brown rice using a 70 × 6-layer gravity separator for a clean, recirculation-free whitening feed

  • Whitens rice with adjustable control for consistent finish across different paddy varieties

  • Grades head rice and brokens for uniform bag quality

  • Enlarged elevator pipes (140 mm single / 250 mm double) prevent flow bottlenecks at higher throughput levels
Why Choose It
  • More output, same floor space: 800–1,000 kg/h versus ZNJ-15's 600–700 kg/h with no increase in machine dimensions

  • Higher capacity through engineering optimization — not added power. Destoner section adds only 0.4 kW compared to ZNJ-15

  • CHINT electrical control cabinet with reduced voltage starting system and one-key emergency stop for safe, reliable daily operation

  • Stainless steel discharge pipes and galvanized air pipes for long-term durability and hygiene compliance

  • 8 units fit in a single standard shipping container — cost-efficient for distributors and multi-site operators

  • Visual inspection windows and quick-access panels for fast daily checks and minimal downtime
Technical Specifications
  • Overall size: 3,700 × 1,560 × 3,400 mm (L × W × H)

  • Rice output capacity: 800–1,000 kg/h (~20 TPD)

  • Paddy processing capacity: 1,300–1,600 kg/h

  • Husker: 8-inch gearless paddy husker
  • Gravity separator: 70 × 6-layer gravity paddy separator

  • Cleaner & destoner: 56-type cylinder cleaner & destoner (drawer-type)

  • Single elevator pipe width: 140 mm

  • Double elevator pipe width: 250 mm

  • Electrical control: CHINT cabinet with reduced voltage starting system

  • Safety features: Full protection covers, visual inspection windows, one-key emergency stop

  • Discharge pipes: Stainless steel

  • Air pipes: Galvanized

  • Frame: Steel structure

  • Container loading: 8 sets per 20-ft container

  • Country of origin: China

Recommended Applications

Deploy the ZNJ-25 as a central processing line for commercial rice mills, township cooperatives, and medium-scale agricultural processing plants targeting ~20 TPD output, where a compact footprint, higher throughput, and straightforward maintenance are essential for stable quality and consistent daily production."

Service and Warranty

12-month warranty from shipment (consumables excluded). Includes commissioning guidance, operator training documentation, and preventive-maintenance checklists, plus lifetime remote support. Genuine spares are stocked with fast dispatch; on-site technician service can be scheduled when required. (Details per technical/commercial documentation.)

Enlarged Elevator Conveying System

Single pipe widened to 140 mm, double pipe to 250 mm — eliminating flow bottlenecks and keeping grain moving at full throughput without recirculation.

8-Inch Gearless Paddy Husker

Larger husking chamber processes more paddy per pass while the gearless drive reduces vibration, heat build-up, and maintenance frequency at continuous high output.

Reduced Voltage Starting System

Soft-start circuitry limits inrush current at startup, reducing electrical stress on the motor and CHINT control cabinet for longer component service life.

6-Layer Gravity Paddy Separator

Six separation layers achieve a cleaner paddy/brown rice split with fewer recirculation passes — protecting head-rice yield and reducing load on the whitening section.

Drawer-Type Destoner

The stone tray pulls out without tools for fast discharge and sieve inspection — daily cleaning in under two minutes with no disassembly required.

Stainless Steel Discharge Pipes

All grain-contact discharge points use stainless steel — corrosion-resistant, food-safe, and built to outlast standard painted mild steel in humid milling environments.

High-volume cleaning, zero bottlenecks

Pre-Clean + De-Stone, Together

The 56-type cylinder cleaner removes large and fine impurities while the integrated drawer-type destoner ejects stones by density — delivering cleaner paddy input and protecting downstream husking at up to 1.3–1.6 t/h

Clean brown, fewer recircs

8-Inch Husking + 6-Layer Separation

The gearless 8-inch husker opens hulls with low grain stress, then the 70 × 6-layer gravity separator splits unhulled paddy from clean brown rice — returning only what needs re-husking and sending the rest straight to whitening.

Consistent finish, every batch

Iron-Roll Whitening at 20 TPD Scale

Air-assisted whitening with adjustable pressure and gap settings handles multiple paddy varieties — uniform abrasion, low breakage, and cleaner kernels at continuous 800–1,000 kg/h throughput.

Compact, service-ready design

One Station. More Output

Cleaning, de-stoning, husking, separation, and whitening on the same compact footprint as ZNJ-15 — with enlarged elevator pipes, quick-access panels, and visual inspection windows built for 20 TPD lines that are easy to run and maintain.
Installation & Service

Installation and maintenance notes

Install the ZNJ-25 on a stable, level, and ventilated floor with adequate dust extraction. Check electrical grounding and verify all safety protection covers are correctly fitted before first operation. Commission in sequence: power on the CHINT control cabinet → elevators → cylinder cleaner & destoner → gearless husker → gravity paddy separator → whitening section. Confirm rotation directions and listen for irregular sounds during the initial no-load run.

During operation, maintain a steady paddy feed rate, monitor amperage and temperature, and clear any chokes immediately. After shutdown, isolate power and allow all shafts to fully stop before approaching the machine. Regularly clean sieves, cylinders, and discharge points; replace worn parts promptly. Grease bearings per the recommended schedule and recheck belt and chain tension periodically. Wear eye and ear protection and a dust mask whenever inspection panels are open.
