Lower moisture · prevent loss · preserve grain quality
The Problem
Grain is harvested at up to 18–30% moisture, but safe storage requires 13–14%. If not dried within 24–48 hours, molds multiply extremely fast in heat and humidity, and aflatoxin above limits renders the entire batch commercially worthless — in some countries even meeting the threshold for mandatory destruction. For large-scale growers and storage enterprises, such loss can be catastrophic.
Comparison of three drying solutions
Tower drying
22–500 TPD continuous For large collection centers PLC automatic operation 24-hour continuous running
Batch drying
3–25 t/batch Fixed and mobile types For small/medium farms Low investment cost Easy operation

Frequently Asked Questions
Why must harvested grain be dried as soon as possible?
Grain is harvested at 18-30% moisture but safe storage needs 13-14%. If not dried within 24-48 hours, molds multiply fast in heat and humidity and aflatoxin above limits can make the whole batch worthless - in some countries even forcing mandatory destruction. For large growers and storage enterprises such loss can be catastrophic.
How to choose between tower, batch and seed drying?
Tower dryers 22-500 TPD run continuously, suited to large collection centers with PLC auto 24/7 operation. Batch dryers 3-25 t/batch (fixed and mobile) suit small/medium farms with low investment and easy operation. Seed dryers use <=40C low-temperature high-volume drying to keep germination >=95%, for seed companies and breeding stations.
Which heat source is most economical?
Where coal is abundant use coal (lowest unit heat cost); where natural gas pipelines exist use gas (cleaner); where agricultural waste is rich use biomass pellets (self-produced waste, lowest cost and carbon-neutral); where power is abundant with strict eco rules use electric (zero emission). We recommend by local fuel availability and compliance.
