Continuous Grain Drying Tower with Low Broken Rice Rate

Product Specification

Product Core Positioning

    The WGH Series Continuous Grain Drying Tower is an industrial-grade continuous drying equipment developed by Wangu Machinery for large grain depots, grain & oil processing enterprises, and national grain reserve projects. Unlike traditional batch dryers, the WGH series adopts continuous feeding and discharging operation mode — grain flows through the entire drying process without interruption. With daily capacity ranging from 100 to 1000 tons, it is the genuine industrial solution for large-scale grain drying operations.

Process Flow Overview

    Wet grain is lifted to the tower top by bucket elevator → grain distribution device spreads evenly → concurrent-flow drying section (high-temp rapid moisture removal) → counter-flow drying section (medium-temp deep drying) → tempering section (moisture equalization, reduce cracking) → cooling section (cool to safe temperature) → continuous discharge → online moisture detection → qualified grain out to storage.

Best-Selling Features & Equipment Advantages

1,Continuous High Capacity--High-temperature hot air flows in the same direction as grains to rapidly evaporate surface moisture and greatly reduce the initial high moisture content.--Grains are fed and discharged continuously without batch waiting, enabling 24-hour non-stop operation with a daily processing capacity ranging from 100 to 1,000 tons.

2,Combined Concurrent-Counter-flow--Rapid moisture reduction in the concurrent flow section combined with in-depth and uniform drying in the counter flow section balances high efficiency and superior grain quality.--Compared with single drying processes, this system reduces energy consumption by 15–20% and delivers superior grain quality after drying.

3,Up to 25% Moisture Reduction--High-moisture grains can be dried down to safe moisture content in a single pass, eliminating the need for multiple recirculation drying cycles.--It saves time, fuel and labor, cutting the overall comprehensive cost by more than 30%.

4,Low-Temp Quality Protection--The grain temperature is strictly controlled at ≤55°C. Equipped with tempering process, the incremental broken grain rate is less than 0.5%.--In rice processing, approximately 50 tons of head rice can be additionally obtained from every 10,000 tons of paddy, which directly boosts economic profits.

5,Indirect Heating, No Pollution--Flue gas is completely isolated from grains. Adopting an all-steel tubular heat exchanger, the generated hot air is clean and odor-free.--The dried grains are safe and hygienic, complying with food-grade standards, and suitable for both processing grains and seed grains.

6,Multi-Fuel Compatible--It supports five heat sources: coal, fuel oil, natural gas, biomass (straw and rice husk), and steam.--Users can flexibly select the most cost-effective fuel according to local energy prices. Firewood is available for application in Africa, and rice husk can be adopted in Southeast Asia.

7,PLC Full Automatic Control--It adopts touch screen operation, which can automatically monitor moisture content, temperature and material level, and supports remote monitoring and mobile APP control.--A single operator can monitor multiple drying lines simultaneously, reducing labor costs by more than 80%.

8,Energy Saving & Eco-Friendly--Adopting multiple energy-saving technologies, the unit heat consumption ranges from 5000 to 7000 kJ per kilogram of evaporated water, and the unit is equipped with a bag dust removal system.--The equipment complies with national environmental protection emission standards to avoid environmental penalties, and users can access environmental subsidies in some regions.
