1. Core Advantages — Why Choose Our Belt Dryer?
Low‑temperature Freshness Lock & Premium Quality
Equipped with multi‑layer mesh belt and zoned temperature control (40–75°C), the equipment removes moisture slowly and gently. It effectively retains chlorophyll, vitamin C and other nutrients of vegetables. The finished products feature fresh color and full texture after rehydration.
Continuous Large‑scale Production
Fully automatic feeding, drying, material turning and discharging realize streamlined production. The single line daily fresh vegetable processing capacity reaches 10–50 tons, suitable for diversified materials such as carrots, spinach and mushrooms.
Energy Saving & Cost Reduction
The hot air circulation utilization rate exceeds 70%, saving 40%–60% energy compared with traditional drying rooms, and reducing the comprehensive drying cost by 30%.
2. Technical Highlights — High-efficiency Vegetable Drying Technology
Optimized Preprocessing
Fresh vegetables go through cleaning, cutting and blanching for color protection, followed by centrifugal predehydration to 60%–70% moisture content, greatly shortening the overall drying cycle.
Four‑stage Drying Process
Preheating Stage (40–50°C): Uniform heating to prevent material surface hardening.
Constant-speed Drying Stage (60–70°C): Rapid removal of free water.
Slow Drying Stage (50–60°C): Remove bound water without coking or discoloration.
Cooling Stage: Cool materials below 30°C to lock natural color and flavor.
Intelligent Control System
Online moisture meters monitor data in real time and automatically adjust belt speed and hot air temperature. Stable final moisture content: ≤8% for leafy vegetables, ≤5% for rhizome vegetables.
Anti‑adhesion Design
The mesh belt is coated with Teflon or equipped with anti-stick rollers to effectively solve adhesion problems of high-sugar vegetables such as carrots.
3. Application Scenarios
Dehydrated Vegetable Processing Plants
Produce ready-to-eat vegetable crisps, instant noodle ingredients and seasoning materials to meet retail and catering supply demands.
Pre-made & Frozen Food Enterprises
Dry scallions, ginger, garlic and other seasoning vegetables to extend shelf life and reduce cold-chain logistics costs.
Agricultural Deep-processing Enterprises
Solve the problem of unsalable fresh vegetables, convert raw materials into high-value dehydrated products and improve profit margins.
4. Actual Customer Case & Benefit Verification
Spinach Dehydration Production Upgrading Project
Original Pain Points: Traditional hot air oven drying took 12 hours per batch, resulting in yellowed spinach leaves, low rehydration rate and 8% customer return rate.
Customized Solution: Adopted a 5-layer belt dryer with a processing capacity of 2 tons of fresh vegetables per hour, integrated with blanching, pre-cooling and metal detection modules.
Operation Results:
- Drying cycle shortened from 12 hours to 4 hours; daily output increased from 8 tons to 40 tons.
- Vitamin C retention rate increased from 60% to 85%, raising the export product price by 20%.
- Energy cost per ton reduced from ¥280 to ¥120, saving over ¥3 million annually.
