Continuous Grain Drying Tower100-1500 Ton/Day Low Temp Dryer for Paddy Corn

Product Specification

Short Description 

This vertical continuous‑flow grain drying tower is specially designed for pre‑storage moisture reduction of paddy, corn, wheat, soybean, barley, sorghum and other grains. It features continuous feeding and discharging with customizable daily capacity from 30 to 1000 tons. With low‑temperature drying at 45–65℃, it stably reduces grain moisture from 18%–35% to a safe storage level of 12%–14%. The equipment ensures low breakage rate, high efficiency and stable performance, effectively preventing grain mildew, germination and loss caused by damp weather. It is ideal for large‑scale drying operations on farms, grain depots, processing plants and agricultural cooperatives, greatly improving grain quality and economic benefits.

Product Overview

The continuous flow grain drying tower is a vertical, continuous‑operation drying machine for large‑scale grain dehydration and pre‑storage treatment. It replaces traditional sun‑drying and solves common problems such as mildew, germination, rot and quality degradation caused by untimely drying in rainy and humid weather. It enables seamless grain handling from harvest to storage and guarantees long‑term preservation and commercial value of grains.

Adopting a closed continuous‑operation design, the machine runs 24 hours non‑stop with continuous feeding, drying and discharging. Fully automatic operation significantly improves drying efficiency, making it core equipment for modern large‑scale, mechanized and standardized grain processing.

Key Performance & Advantages

1. Customizable Capacity for All Scales
Daily capacity ranges from 30 to 1000 tons and can be fully customized. It perfectly matches small farms, medium cooperatives, large grain depots and grain processing plants without capacity waste.

2. Precise Moisture Control for Safe Storage
It accurately reduces initial grain moisture of 18%–35% to a safe storage range of 12%–14% with adjustable settings. Strict moisture control effectively avoids mildew, insect infestation and germination caused by excess moisture, greatly reducing post‑harvest losses.

3. Low‑Temperature Drying Preserves Grain Quality
Using low‑temperature hot air circulation at 45–65℃, the machine achieves even drying without high‑temperature damage. Grain breakage rate ≤0.5% and drying uniformity ≤±0.5%, keeping grains full‑colored and intact to meet standards for commercial and reserve grain.

4. Multiple Heating Sources & High Energy Efficiency
Compatible with coal, biomass, diesel, natural gas and electric heating to suit local energy conditions. Heat efficiency reaches over 75% with high hot‑air recycling, greatly cutting long‑term operating costs with eco‑friendly performance.

5. Intelligent PLC Automatic Control
Equipped with fully automatic PLC control system, it realizes automatic temperature regulation, online moisture monitoring and auto feeding/discharging. Minimal manual supervision reduces labor costs while ensuring stable operation and easy maintenance.

6. Durable Structure & Long Service Life
Main body is made of high‑quality carbon steel; grain‑contact parts can be stainless steel for anti‑corrosion and anti‑pollution. Tower height 8–22m with stable structure for long‑term outdoor operation. Overall dimensions can be customized based on capacity and site conditions.
