Licorice Dryer Machine — specifically engineered as an Industrial Licorice Root Mesh Belt Dryer Machine For Sale — is your answer to the unique challenges of bulk licorice processing. Raw licorice root carries inherently high moisture content and contains heat-sensitive active compounds like glycyrrhizin that demand precise, gentle drying conditions. This continuous multi-layer drying system delivers exactly that: uniform moisture removal at controlled low temperatures, сохранение цвета, вкус, and pharmacological properties while achieving commercial-scale throughput. Whether processing 500 kg or 5 tons per day, this machine turns a bottleneck operation into a smooth, continuous production line.

The licorice material enters the feeding hopper and spreads evenly onto a stainless steel mesh belt. The belt carries the material through multiple drying zones, each with independently controlled temperature, расход воздуха, and exhaust. Hot air passes vertically through the material layer — from bottom to top in the initial zones (rapid surface moisture removal) and from top to bottom in the later zones (controlled internal moisture diffusion). This cross-ventilation design ensures every piece of licorice receives equal exposure, eliminating the “wet center” problem common in batch dryers. As the material exits the final cooling zone, it is discharged at the desired moisture level, Готовы к упаковке или дальнейшей обработке.

1. Preserves Active Ingredients
Licorice’s key compound — glycyrrhizic acid — begins to degrade above 80°C. Our zoned low-temperature drying keeps the licorice core temperature below 70°C throughout the process. Lab tests show that products dried with this machine retain 93–97% of their original glycyrrhizin content, versus 78–85% with traditional hot air or sun drying methods.

2. Непрерывная операция, Reduced Labor
Unlike tray dryers that require manual loading/unloading and batch-to-batch quality checks, this mesh belt dryer runs continuously. One operator can monitor the entire line. Throughput is predictable and adjustable — simply increase belt speed for thinner licorice slices or decrease it for thicker root chunks.

3. Uniform Moisture Distribution
The vertical air-penetration design, combined with the tumbling action between belt layers, eliminates moisture gradients within the product. Every piece discharged has a moisture variation of less than ±1.5%, compared to ±4–6% in static tray dryers. This is critical for licorice buyers who specify tight moisture specs for extraction or pharmaceutical use.

4. Масштабируемый & Настраиваемый
Standard models process 300–5,000 kg/day (wet basis), but we can customize belt width (1.2–2.5 m), количество слоев (до 10), and heating medium (пар, тепловое масло, природный газ, or electric). The modular frame design allows you to add drying zones later as your production grows, without replacing the whole system.

1. Multi-layer Mesh Belt Design
The dryer uses 4–8 layers of food-grade 304 stainless steel mesh belts stacked vertically. Each layer has independent speed control, allowing the licorice to tumble gently as it transfers from one belt to the next. This reorientation ensures all sides of the material are exposed to airflow, preventing localized over-drying or under-drying.

2. Zoned Temperature & Airflow Control
The drying chamber is divided into 3–6 independent zones (предварительная сушка, основная сушка, final drying, и охлаждение). Each zone has its own heating system, circulation fan, and exhaust damper. For licorice, we typically set pre-drying at 55–60°C (gentle ramp-up to prevent case hardening), main drying at 65–70°C (efficient moisture removal without degrading glycyrrhizin), and final drying at 50°C (equalization).

3. ПЛК + HMI Touchscreen Control System
An integrated Siemens or Mitsubishi PLC controls belt speed, zone temperature, fan frequency, and material layer thickness. The HMI touchscreen displays real-time data — inlet/outlet temperature, влажность, скорость ленты, and estimated production output. До 20 drying recipes can be saved and recalled instantly for different licorice varieties (different root sizes, moisture levels, and cut thicknesses).

4. Energy Recovery & Exhaust Management
A finned-tube heat exchanger recovers waste heat from exhaust air to preheat incoming fresh air, reducing total energy consumption by 25–35%. The exhaust system is equipped with a cyclone separator to capture fine dust particles, keeping the working environment clean and compliant with food processing standards.

• Higher Profit Margins: Less energy consumed per kg of product, fewer rejects from uneven drying, and higher selling prices for premium-grade licorice that meets international pharmacopoeia standards.
• Faster ROI: Continuous production means you process more licorice in less time. Typical payback period is 8–14 months for a mid-scale operation processing 2 тонны/день.
• Соответствие готово: All contact parts are 304 нержавеющая сталь, easy to clean between batches. The design meets CE, ИСО 22000, and GMP guidelines, so your product is audit-ready for EU, US, and Japanese markets.
• Peace of Mind: We provide full installation guidance, operator training, a 12-month warranty on parts, и 24/7 remote technical support. Запчасти (ремни, фанаты, датчики) are stocked and ship within 48 часы.
