Why Do Nuts Need Drying?
Drying nuts before commercial processing is a necessary step before roasting. Its main purpose is to control moisture, ensure quality, and improve efficiency. Skipping drying can cause various quality issues. Key reasons:
Even roasting and better texture
- Raw nuts have high moisture (8%-12%). Roasting directly can burn the outside while leaving the inside raw.
- Low-temperature drying removes surface water first, then high-temperature roasting cooks nuts evenly for consistent taste.
Prevent oil leakage and improve appearance
- High-moisture nuts release internal oil quickly during roasting, causing oily, dark, sticky surfaces.
- Drying reduces moisture to 3%-5%, keeping nuts dry, crispy, and evenly colored.
Reduce mold risk and ensure food safety
- High moisture promotes mold and aflatoxin formation.
- Drying lowers moisture below the safe level, stopping mold growth and reducing toxin risk.
Improve roasting efficiency and save energy
- Removing most free water first means roasting only needs to heat the bound water inside.
- This shortens roasting time by 30%-50%, increases output, and lowers energy use.
Stabilize quality and extend shelf life
- Drying ensures uniform low moisture. Roasted nuts stay crisp, resist softening, and oxidize more slowly.
- Shelf life can be extended to 1–2 years.
Applications
- 堅果： Almonds, peanuts (with shell), walnuts, cashews, hazelnuts, and other common nuts.
- Fruits: Dates, papaya slices, hawthorn slices, apple slices, lemon slices, kiwi, mulberries, etc.
- Vegetables: Asparagus, carrots, green beans, lentils, eggplant, red peppers, chili, cucumber slices, mushrooms, shiitake, ginger slices, garlic slices, etc.
- Herbal Materials: Honeysuckle, nasturtium, burdock, ginseng, mulberries, etc.
Working Principle of Mesh Belt Dryer
The continuous conveyor dryer dries materials by spreading them on a mesh belt, which moves back and forth inside the dryer via a conveyor-driven mechanism. At the same time, hot air passes through the materials, and moisture is expelled through a dehumidifying fan.
Key Features:
- Side baffles: Prevent material from spilling off the belt.
- Observation & maintenance doors: Allow easy monitoring of drying and routine maintenance.
- Stainless steel construction: The chamber walls and belt are made of stainless steel, improving heat efficiency, preventing contamination, and extending service life.
- Mesh belt design: Standard 3 mm openings prevent small particles from falling while ensuring full air circulation.
- Adjustable size: Drying length can be set from 8 to 20 meters, and belt width ranges from 1.2 to 2 meters.
This design ensures uniform, efficient drying for a wide range of materials while maintaining hygiene and durability.
Core Functions of Continuous Nut Drying Machine
- Continuous Production: Automatic feeding → mesh belt conveying → low-temperature drying → automatic discharge; 24/7 operation, 3–5× higher efficiency than batch machines.
- Precise Temperature Control: Adjustable 40–90°C; low-temperature slow drying preserves original flavor and nutrients without scorching.
- Intelligent Humidity Control: Real-time moisture monitoring with automatic dehumidification and air compensation; prevents dampness, mold, or under-drying; stable moisture content.
- Adjustable Air & Belt Speed: Suitable for different nut types and moisture levels; drying uniformity ≥98%.
- Segmented Temperature & Humidity Control: Preheating, constant-speed drying, and deceleration zones remove free water first, then bound water; prevents surface burning and raw interiors.
- Energy-efficient Hot Air Circulation: Increases thermal efficiency by over 30%; even heating with no dead zones.
- Automatic Material Control & Leak Prevention: Anti-leak mesh belt and variable-frequency feeder ensure uniform material distribution and consistent drying results.
- Food-grade Sanitary Design: 304/316 stainless steel, no dead corners, fully enclosed operation; dust- and odor-free; meets GMP standards.
- Automated Control: PLC touchscreen, one-touch process parameter storage; direct recall for material changes; reduces labor.
- Overload & Over-temperature Protection: Automatic shutdown and alarm for equipment and material safety.
- Compatible with Subsequent Roasting: Discharge temperature controllable (≤40°C); can directly connect to roasting machines for integrated “drying + roasting” production.
