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 sala de secagem da bomba de calor 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.

Lavagem de Legumes
Diferentes legumes requerem diferentes máquinas de lavagem. Legumes folhosos geralmente são lavados com lavadoras de folhas de vórtice. Legumes de raiz, como batatas, frequentemente usam rolos de escova, que também podem descascar. Tomates, pimenta e legumes semelhantes geralmente usam lavadoras de bolhas. Para branqueamento ou esterilização, podem ser usadas máquinas com funções de ozono ou branqueadores de legumes.
Descasque e Corte
Legumes com pele podem ser descascados com uma máquina de descasque. Legumes folhosos geralmente são cortados com um cortador de legumes.
Fatiar ou Ralar
Legumes que precisam de fatiar ou ralar podem ser processados com fatiadoras ou raladoras. Algumas máquinas combinam descasque e ralar em um só passo.
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: Secador de correia de malha 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:
| Modelo | Belt Width | Drying Length | Camadas | Capacity (kg/h) | Potência Total (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
- Controle preciso de temperatura e humidade
- Food-grade stainless steel chamber and trays
- Suitable for delicate vegetables, herbs, and high-value products
Typical Specifications:
| Modelo | Dimensions (mm) | Drying Crews | Capacity per Batch (kg) | Fonte de Calor |
|---|---|---|---|---|
| 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:
| Modelo | Bandejas | 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.
Embalagem
Legumes secos precisam ser embalados usando máquinas automáticas ou semi-automáticas de embalagem de legumes com pesagem. Garanta vedação adequada para armazenamento e transporte.
Este é um processo geral. Diferentes legumes podem requerer etapas diferentes. Por exemplo, pimenta pode precisar de uma máquina de remoção de talos. Ao consultar, sempre especifique o tipo de legumes que planeja processar.
