Parchment Coffee Testing Dehuller

Seven Core Product Advantages

Advantage 1: Zero Breakage Precision Dehulling, Compatible with All Coffee Processing Methods

Soft dehulling via differential-speed rubber rollers eliminates harsh grinding with iron rollers.

- Single-pass dehulling rate: 70%–80%

• Repeated processing (2–3 passes): dehulling rate ≥99%

• Bean breakage increase rate: ≤1%

  Suitable for washed, natural/dry-process, and honey-process parchment coffee. Integrated air winnowing delivers pure, impurity-free green coffee samples.

  Advantage 2: Dual Adjustable Infinite Pressure, No Parts Replacement for Raw Material Switching

  Dual regulation system: spring compression force + push rod roller gap adjustment. Adapts to coffee beans of varying sizes, moisture contents and varieties. Transparent observation window enables intuitive operation for novice users; no consumable replacement required when switching raw materials.

   

   

  Advantage 3: Integrated Built-In Dust Extraction, Dust-Free Eco-Friendly Operation

  All-in-one dust removal ductwork confines dust at the source, complying with environmental protection standards. Supports connection to centralized external dust collection, reducing abrasive dust wear on rubber rollers and transmission components to cut maintenance frequency.

   

   

  Advantage 4: Lightweight Compact Frame, Portable for On-Site Sampling

  Net weight only 50 kg, overall dimensions 710×360×690 mm — fits easily in car trunks. Minimal floor footprint; single-person quick assembly and commissioning, ideal for Coffee Plantation and laboratory settings.

   

   

  Advantage 5: Modular Open Structure for Easy Maintenance & Cleaning

  Four independent detachable modules: feeding unit, dehulling roller assembly, fan unit and discharge unit. Quick disassembly of wear parts (rubber rollers, fans); simplified daily cleaning and troubleshooting to lower long-term operation & maintenance costs.

   

  Advantage 6: Fully Automatic Closed-Loop Processing, Energy-Saving & Labor-Free

   

   

  Fully automated continuous workflow: feeding → dehulling → air separation → split discharge. Hourly capacity of 20 kg; single batch capacity 50–500 g, optimized for high-frequency laboratory testing. Low-consumption 0.37 kW single-phase 220V motor minimizes long-term electricity expenditure.

   

   

  Advantage 7: Dual-Purpose Design, Universal for Full-Sector Coffee Testing

  Dual functionality for green coffee yield testing and small-batch laboratory processing. Widely adopted by coffee inspection institutions, processing plant labs, agricultural & forestry universities, and raw coffee procurement quality inspection stations.

Supplementary Section 1: Streamlined Working Flow

1. Even Feeding: Load 50–500 g parchment coffee beans; consistent feeding without blockages

2. Roller Dehulling: Differential-speed rubber rollers gently compress and tear to fully strip parchment husks

3. Air Winnowing: Light husks and defective shriveled beans are extracted by airflow; intact dense green beans fall by gravity

4. Classified Collection: Separate discharge channels for clean green beans, husks and foreign impurities
