蔬菜干燥生产线

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 热泵烘干房 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.

蔬菜干燥生产线的应用

去皮和切割

带皮的蔬菜可以用去皮机去皮。叶菜类通常用蔬菜切割机切割。

切片或切丝

需要切片或切丝的蔬菜可以用切片机或切丝机加工。有些机器结合了去皮和切丝的功能。

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: 网带式干燥机 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:

模型	Belt Width	Drying Length	层数	Capacity (kg/h)	总功率（千瓦）
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米	10 m	5	120–300	15.8
SL-2-20	2米	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
• 温湿度精确控制
• Food-grade stainless steel chamber and trays
• Suitable for delicate vegetables, herbs, and high-value products

Typical Specifications:

模型	Dimensions (mm)	Drying Crews	Capacity per Batch (kg)	热源
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:

模型	托盘	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.

包装

干蔬菜需要使用自动或半自动称重蔬菜包装机进行包装。确保密封良好以便储存和运输。

这是一个通用流程。不同蔬菜可能需要不同的步骤。例如，辣椒可能需要去茎机。在咨询时，请明确您计划加工的蔬菜类型。

How to Choose the Right Dryer for Your Vegetable Drying Production Line?

Factor	网带式干燥机	Heat Pump Drying Room	Stainless Steel Tray Dryer
