Intelligent Thermostatic Low Damage Mixed‑Counter Flow Dryer Tower for Corn and Rice
Company Introduction
Zhengzhou Wangu Machinery Co., Ltd.Founded in 1998, we are a national high‑tech enterprise and one of the institutions participating in drafting national standards for grain dryers. Equipped with a provincial technical R&D center, we sell machinery domestically and globally. We are capable of delivering complete turnkey grain drying projects, offering customised equipment, on‑site installation guidance and professional overseas after‑sales technical support.
Product Brief
Wangu continuous mixed‑counter flow grain drying tower integrates mixed‑flow drying and counter‑flow cooling mature technology. Grains flow down slowly by gravity and exchange heat alternately with hot air. The whole workflow including drying, tempering and cooling operates continuously.
Adopting indirect heating mode, clean hot air touches grains without flue gas pollution. The dryer runs non‑stop for 24 hours to process large quantities of high‑moisture grain. It effectively prevents grains from mildewing and sprouting after harvest, lowering moisture to the safe level for long‑term storage and international grain trade.

Product Features & Practical Advantages for BuyersCore Features
1. Composite mixed‑counter flow duct structure
Angled box air ducts allow hot air to penetrate grain layers from multiple directions. Alternating drying and tempering helps internal moisture escape gradually before counter‑flow cooling, achieving far better drying effect than ordinary dryers.
2. Indirect heat exchange for clean hot air
The combustion chamber is fully separated from the hot air pipeline. Grains stay free from soot contamination and maintain good appearance, satisfying strict inspection standards for edible grains and seed exports.
3. Massive non‑stop production
24‑hour continuous feeding, drying and discharging enables high throughput during harvest peak seasons.
4. Fully automatic PLC intelligent management
Variable‑frequency feeding speed regulation together with real‑time temperature monitoring. The system triggers alarms for overheating and material blockage, requiring minimal manual labour.
5. Wide compatibility of heat sources
Customers may utilise local cheap biomass waste or fossil fuels such as natural gas to match regional fuel supplies.
6. Thickened anti‑corrosion modular steel framework
Key components are heat‑resistant and corrosion‑proof. Modular structure simplifies sea transportation and quick field assembly overseas.
7. Multi‑functional equipment
Simply adjust operational parameters to dry cereals, oil crops and seeds for diversified business development.
Tangible Benefits to Increase Your Profit
1. Preserve grain quality to raise sales revenue
Low‑temperature tempering limits rice fissuring and corn cracking. Premium‑grade grains gain higher market prices and easily pass international export inspections. Seed grains retain high germination rates after drying.
2. Prevent heavy economic losses from moulding
Timely moisture reduction stops wet grains from rotting in rainy weather. You can stockpile grains and resell them at favourable prices off‑season.
3. High thermal efficiency cuts long‑term operational expenditure
Optimised heat exchange reduces fuel consumption compared with traditional cross‑flow dryers. Variable‑frequency fans also save electricity costs year‑round.
4. Expand profit channels
Apart from drying your own grains, you can provide paid drying services for surrounding farmers and grain merchants to gain extra stable income.
5. Full‑package engineering service overseas
We supply integrated turnkey solutions including preliminary layout design, equipment manufacturing, field commissioning, staff operation training and permanent spare parts supply. Remote technical support is accessible for overseas clients.
Welcome to contact us for detailed quotation, layout drawing and customised project solution. We tailor processing capacity and heat source schemes in accordance with your local practical conditions.
