Grain Drying Equipment — The Critical First Step from Field to Silo
Continuous tower dryers · batch circulating dryers · static maize-ear dryers · five heat-source options for grain conditions worldwide
Why is drying the most important post-harvest step?
Grain is typically harvested at 18–30% moisture, but safe storage requires reducing it to 13–14%. Without timely drying, molds multiply rapidly in hot, humid conditions, and aflatoxin levels above limits render an entire batch commercially worthless — an irreversible economic loss. Professional drying equipment is the first line of defense for grain quality and storage safety.
I. Continuous Tower Dryers — 5HL Series
The 5HL series is AmGrainTech's flagship line, built for large grain storage enterprises, grain depots, and port transshipment terminals. It runs continuously 24/7 with a design service life of over 20 years.
Key advantages: uniform drying, staged temperature control, energy savings, five heat-source options, fully automated control, and remote monitoring via a mobile app.

The full range covers 100–1,000 TPD across nine models: 5HL-100/120/150/200/300/500/600/800/1000. Moisture reduction is 13–15% (from 25% down to a safe 14%), and capacity and heat source can be customized. Contact our sales team for more models.
II. Batch Circulating Dryers — 5HX Series
The 5HX series uses a low-temperature, constant-heat drying process and comes in fixed and mobile versions. Batch capacity is 3–35 t/batch, requires no major civil works, and is ready to use on installation. Suited to family farms, agricultural cooperatives, large grain growers, and emergency reserves.
Key advantages: site-flexible and easy to deploy, with options to purchase, lease, requisition for emergencies, or operate across regions. A color touchscreen and mobile connectivity enable remote monitoring.

III. Maize-Ear Dryers — 5HX Static Series
A static drying system designed for maize seed, using a low-to-moderate-temperature hot-air circulation process with no mechanical damage and a germination rate of ≥95%. Available in horizontal and vertical configurations for seed companies and large breeding bases.
Representative models
| Type | Model | Capacity | Dimensions (mm) | Total power (kW) |
|---|---|---|---|---|
| Horizontal | 5HX-50H | 50 t class | 16000×3000×3000 | 250 |
| Horizontal | 5HX-20H | 20 t class | 8000×3000×3000 | 100 |
| Vertical | 5HX-50V | 50 t class | 3500×3000×15000 | 250 |
| Vertical | 5HX-20V | 20 t class | 3000×3000×7000 | 100 |
The horizontal series has five models (5/10/20/30/50 t class) and the vertical series has three (20/30/50 t class). Contact our sales team for more models.
Heat sources: A/B/C tracks — there is an option for you
Type A · Natural gas / Diesel
Clean hot air and precise temperature control, suited to regions with strict environmental rules and food-grade drying. Natural gas cost depends on local pipeline coverage.
Type B · Coal / Biomass
Coal offers high calorific value at the lowest cost. Biomass pellets (rice husk/straw/wood chips) reuse agricultural waste — carbon-neutral with near-zero fuel cost.
Type C · Electric
Zero emissions and fully automated, suited to areas with abundant power and strict environmental regulation. A complete electric heating drying solution is available.
Smart control makes drying simple
All models come standard with a PLC intelligent control system that automates the full cycle from loading to discharge: an intuitive color touchscreen HMI, remote monitoring via a mobile app, and, on large towers, dynamic light displays simulating the drying process. Standard functions include automatic full-level sensing, real-time hot-air temperature monitoring, multi-point grain temperature monitoring, automatic load reduction on overheat, a circulation confirmation system that checks grain flow in real time, and a timer on/off. An online moisture meter is available as an option for real-time discharge-moisture monitoring.
