A vegetable drying production line is a complete automated system that takes fresh vegetables from receiving to packaged dried product. Shuliy designs and supplies full lines that integrate washing, peeling, cutting, blanching, dehydration, drying, and packaging. Depending on your raw material and target product, the drying section can use a mesh belt dryer for continuous output of 400–14,000 kg/h, a heat pump drying room for batch processing of 300–8,000 kg per load, or a stainless steel tray dryer for small runs of 30–240 kg per batch.
This line replaces manual sun-drying and disconnected single machines. It gives vegetable processors stable output, food-grade hygiene, and the ability to run 8–24 hours per day. Shuliy has delivered drying solutions to buyers in 30+ countries for more than 20 years. Every project is backed by layout design, installation support, and a one-year warranty with lifetime technical service.
Why Do Processors Need a Complete Vegetable Drying Line?
Fresh vegetables contain 80–95% water and spoil within days. Sun drying depends on weather and exposes food to dust, insects, and contamination. A fully automatic vegetable drying production line solves these problems by controlling every step:
- Washing and cleaning remove soil and pesticide residue.
- Cutting creates uniform pieces for even drying.
- Blanching stops enzyme activity that causes color and flavor loss.
- Drying reduces moisture to 5–12% for long shelf life.
- Packaging protects the finished product during storage and transport.
With one integrated system, you reduce labor, improve food safety, and produce a consistent, export-grade dried vegetable product.

Lavage des légumes
Différents légumes nécessitent différents laveurs. Les légumes à feuilles sont généralement lavés avec des laveurs à vortex. Les légumes racines, comme les pommes de terre, utilisent souvent des rouleaux brosseurs, qui peuvent aussi les éplucher. Les tomates, piments, et légumes similaires utilisent généralement des laveurs à bulles. Pour le blanchiment ou la stérilisation, des machines avec fonctions d'ozone ou des blanchisseurs de légumes peuvent être utilisées.
Pelage et coupe
Les légumes avec peau peuvent être pelés avec une machine de pelage. Les légumes à feuilles sont généralement coupés avec une coupe-légumes.
Tranchage ou râpage
Les légumes nécessitant un tranchage ou un râpage peuvent être traités avec des trancheuses ou des râpeuses. Certaines machines combinent pelage et râpage en une seule étape.
Main Drying Options
The dryer is the core of the vegetable drying production line. Shuliy offers three proven machine types. Each has a different production style and price point.
Option 1: Sèche-bande à mailles for Continuous Large-Scale Production
The mesh belt dryer is the best choice for processors who need high capacity and continuous operation. Vegetables are spread automatically on a stainless steel mesh belt and move through multiple temperature zones. Hot air passes through the layer from above and below.
Key Features:
- Continuous feeding and discharge, 24-hour operation
- Multi-layer belt design saves floor space
- PLC control of temperature, humidity, and belt speed
- Heat sources: heat pump, electric, gas, coal, biomass, steam
- Stainless steel food-contact parts
Typical Specifications:
| Modèle | Belt Width | Drying Length | Couches | Capacity (kg/h) | Puissance totale (kW) |
|---|---|---|---|---|---|
| SL-1.2-8 | 1.2 m | 8 m | 4 | 60–160 | 11.4 |
| SL-1.6-10 | 1.6 m | 10 m | 5 | 95–250 | 13.6 |
| SL-2-10 | 2 m | 10 m | 5 | 120–300 | 15.8 |
| SL-2-20 | 2 m | 20 m | 10 | 240–600 | 36.8 |
Larger custom models handle several tons per hour. This machine is ideal for chili, carrot, onion, garlic, potato, cabbage, and leafy vegetable drying.
Option 2: Heat Pump Drying Room for Batch Processing
The heat pump drying room is a sealed box-type dryer loaded with trolleys and trays. It is best for processors who want lower investment, simple operation, and premium product quality.
Key Features:
- Batch capacity from 300 kg to 8,000 kg per load
- Air-source heat pump saves 30–50% energy vs electric heating
- Contrôle précis de la température et de l'humidité
- Food-grade stainless steel chamber and trays
- Suitable for delicate vegetables, herbs, and high-value products
Typical Specifications:
| Modèle | Dimensions (mm) | Drying Crews | Capacity per Batch (kg) | Source de chaleur |
|---|---|---|---|---|
| SL-2 | 4000 × 1860 × 2500 | 2 | 300–600 | Heat pump / Electric / Coal / Hybrid |
| SL-6 | 7200 × 2300 × 2500 | 6 | 800–1500 | Heat pump / Electric / Coal / Hybrid |
| SL-10 | 10000 × 2300 × 2500 | 10 | 1200–2500 | Heat pump / Electric / Coal / Hybrid |
| SL-18 | 8500 × 5000 × 2500 | 18 | 4000–6500 | Heat pump / Electric / Coal / Hybrid |
| SL-24 | 12000 × 5000 × 2500 | 24 | 5000–8000 | Heat pump / Electric / Coal / Hybrid |
This option suits small to medium factories, organic producers, and businesses that process multiple products in smaller batches.
Option 3: Stainless Steel Tray Dryer for Small to Medium Output
The stainless steel drying machine is a compact cabinet-style batch dryer. Trays slide into a vertical chamber, and hot air circulates through each layer.
Key Features:
- Small footprint, easy to move and install
- All stainless steel construction for hygiene
- Electric or steam heating
- Best for R&D, small workshops, and sample production
Typical Specifications:
| Modèle | Plateaux | Capacity per Batch (kg) | Power (kW) | Heating |
|---|---|---|---|---|
| SL-24 | 24 | 30–60 | 6–12 | Electric / Steam |
| SL-48 | 48 | 60–120 | 12–24 | Electric / Steam |
| SL-96 | 96 | 120–240 | 18–36 | Electric / Steam |
This machine is often used as a test unit before scaling up to a mesh belt dryer or drying room.
Emballage
Les légumes séchés doivent être emballés à l'aide de machines d'emballage à poids automatique ou semi-automatique. Assurez une bonne étanchéité pour le stockage et le transport.
Il s'agit d'un processus général. Différents légumes peuvent nécessiter différentes étapes. Par exemple, le piment peut nécessiter une machine de retrait de tige. Lors de la consultation, précisez toujours le type de légumes que vous souhaitez traiter.
