Efficient continuous low‑temperature drying reducing breakage preserving grain

Product Specification

   The WGH continuous drying tower is a large‑scale grain‑drying professional equipment developed by Zhengzhou Wangu Machinery, specially designed for grain depots, grain cooperatives, grain‑oil processing plants and grain‑trading enterprises. It performs continuous dehydration for high‑moisture raw grains including corn, paddy, wheat, soybean, sorghum, rapeseed and other materials, stably reducing grain moisture to safe storage level so as to avoid mildew and germination losses. Adopting vertical mixed‑flow combined with counter‑current & concurrent‑flow process, grains flow downwards by gravity continuously. Equipped with intelligent temperature control and grain‑discharge regulating system, the unit satisfies large‑volume non‑stop drying and serves as a preferred solution for continuous grain industrial production.

The tower consists of multi‑section drying zones, tempering zones and cooling zones. The tempering process balances moisture inside and outside grain kernels and effectively lowers grain cracking rate. Sufficient heat exchange takes place between hot air and grains without dead drying spots for stable finished‑grain quality. Compared with conventional drying equipment, this tower features outstanding advantages in energy‑saving performance, grain quality preservation and long‑term continuous operation reliability.

Main Features

• Large processing capacity: Large‑cross‑section tower structure supports massive daily drying output to meet high‑volume grain processing in harvest seasons.

• Heavy‑duty industrial configuration: Modular hot‑dip galvanized steel tower body plus reinforced load‑bearing frame, anti‑corrosion and anti‑aging for long‑term outdoor operation.

• Fully‑automatic continuous operation: Continuous wet‑grain feeding and stable dry‑grain discharging, 24‑hour non‑stop production without intermittent shutdown.

• Uniform drying & low breakage rate: Multi‑stage drying together with tempering sections realize gradient low‑temperature drying. Grains are heated evenly to guarantee commercial grain quality.

• Complete model range: Multiple specifications from 100 t to 1000 t are available, suitable for small cooperatives up to large‑scale grain depots.

• Stable intelligent operation: Built‑in PLC intelligent control system, supporting online moisture monitoring, automatic adjustment of hot‑air temperature and grain‑discharge speed to ensure stable production of processing plants.

• Wide heat‑source adaptability: Compatible with natural gas, biomass, coal‑fired, steam and other hot‑air heat sources to fit local energy conditions.

Technical Parameters

Application Fields

   This continuous drying tower is widely applied in national grain reserves, grain‑oil mills, planting cooperatives, port grain logistics and oil‑processing industries. It is mainly used for drying corn, paddy, wheat, soybean, sorghum, millet, rapeseed and other grains & oil‑bearing crops. It adopts indirect heat‑exchange with clean hot air; fuel flue gas keeps separated from grains so that finished grains stay clean and contamination‑free. Drying parameters can be flexibly adjusted to process high‑moisture raw grains of different initial water contents. The finished products feature uniform moisture and resist heating & mildew during long‑term storage. The equipment allows open‑air installation and can be equipped with dust‑removal system to meet environmental‑protection exhaust requirements.

Packaging & Quality Assurance
