Girculating Grain Dryer- Low‑temperature drying tempering low grain breakage retain seed germination rate

   The 5HH‑30 batch‑circulating grain dryer manufactured by Zhengzhou Wangu Machinery is specially designed for agricultural cooperatives, grain purchasing stations and small‑medium grain depots. It can dehydrate granular grains such as corn, paddy, wheat, soybean, sorghum, rapeseed and seed grain. High‑moisture grain is processed through repeated drying and adequate tempering cycles, delivering grain with stable & uniform moisture, low cracking rate and good storage performance.

Featuring vertical tower‑type structure, the equipment integrates elevator, grain circulation, drying, tempering and cooling all‑in‑one. Grains keep circulating and flowing down with alternate drying‑tempering procedures. Low‑temperature drying protects grain quality and avoids local over‑drying. Compared with conventional simple dryers, this machine has lower breakage rate, remarkable energy‑saving effect and reliable long‑time running performance.

Main Features

   Flexible batch operation: 30‑ton batch loading capacity, meeting drying requirements for small‑and‑medium grain purchasing business.
Low‑temperature tempering: Alternating drying and tempering effectively reduce grain cracking and maintain germination rate for seed grains.
Intelligent automatic control: PLC touch‑screen system equipped with online moisture sensor. It will auto‑stop and discharge material once target moisture is achieved. Audio‑visual fault alarm facilitates quick troubleshooting.
Uniform drying: Multi‑layer angle‑box air distribution improves hot‑air permeability and guarantees consistent grain moisture.
Various model options: 5HH‑15, 5HH‑30 and other models available for different production scales.
Stable operation: Hot‑dip galvanized anti‑corrosion steel plates; variable‑frequency elevator drive; audio‑visual fault alarm to reduce maintenance workload.

Application Fields

   This circulating grain dryer is widely used in family farms, agricultural cooperatives, grain traders, small‑medium grain depots and rice mills. It is especially fit for post‑harvest drying of high‑moisture paddy, corn, wheat, as well as rapeseed, sorghum and various grain seeds. It applies indirect clean hot‑air heat exchange. Flue gas is fully separated from grains to ensure contamination‑free finished products. Adjustable drying temperature supports both commercial grain and seed processing. Large moisture‑reduction capacity can bring high‑moisture raw grain down to safe storage moisture.
