This tower dryer comes in two models: 5HXG-15 and 5HXG-32. Maximum capacities: corn 3,400kg/h, wheat 3,250kg/h, rice 3,500kg/h, rapeseed 2,600kg/h.
粮食烘干机还具有广泛的适用性，尤其适用于颗粒状粮食如玉米、稻谷、大豆、油菜籽等。目前我们的第四代是全球最先进的粮食干燥机；它是粮机领域的一次革命，将为粮食收获带来巨大收益！
混流粮食烘干机原理
当粮食干燥塔开始装粮时，料斗中的粮食被提升机提升至主仓顶部，然后通过上部绞龙将粮食送入干燥箱内，直至装满。
干燥过程中，谷物排放物不断地将干燥段底部的谷物排出至下搅拌器，下搅拌器将谷物送至提升机提升至上搅拌器，上搅拌器将谷物送至调温区。在自身重力的作用下，调温区的谷物缓慢地从上到下移动到四个干燥区。
The air heated indirectly by the hot blast stove is sent to the hot blast chamber of the drying section under the action of a centrifugal-induced draft fan. The hot blast continuously crosses the thin grain layer of the drying section from the hot blast chamber, and the flow direction of the hot blast crosses the direction of grain movement.
In this way, the hot airflow and the grains have sufficient contact, so that the grains are heated and dehumidified. The waste gas is discharged from the machine from the waste gas chamber. In this way, the drying cycle is realized over and over again until the moisture content of the grain meets the required standard.
Composition of the mixed flow cereal dryer
Two different bases for different materials
The gravity-fed base eliminates the screw conveyor, reducing grain breakage caused by collisions with conveyor blades, making it suitable for drying larger grains.
Base with screw conveyor for material with low specific gravity.

混流式谷物烘干机的优点
- Low application power: The total power of the grain drying tower (50 tons per day) is 7.6KW. It can be used with general agricultural electricity; no transformer is needed, and the installation is convenient.
- 高烘干效率：采用智能烘干技术，自动调节烘干温度和时间，满足不同湿度谷物的要求。低温烘干使谷物受热均匀，爆腰率低，发芽率高。烘干后谷粒饱满，保证谷物品质。
- 低热耗和节能：烘干机采用低温恒温，利用热交换气体的清洁能源，充分覆盖烘干无死角，无二次污染。性能稳定，烘干水分内外一致，使谷物不易霉变，便于长期储存。
- Long service life: The main components of the dryer are thickened plates and stainless steel runners. The paint surface of the dryer is painted with electrostatic spray paint (more than 5 times the life of general spray paint).
- 低烘干成本：我公司新型烘干机采用斜式进风，通风顺畅，烘干均匀，全年无需清理。

为什么选择我们的低温循环塔式干燥机？
The grain drying generally only lasts ten to twenty days, and it belongs to continuous work, which requires high stability and continuous operation during the process. This also puts forward higher requirements for the dryer in the material application and wear-resistant material.
Standard version vs. Our version
Standard version
- The oldest type of dryer has a simple design, high power consumption, high energy use, and is prone to fire.
- The cross-flow drying layer is 1.4 m high, with poor ventilation, many dead corners, and uneven drying, achieving only about 0.7% moisture reduction.
- Common mesh plates and cross-flow dryers often get clogged by rice husks.
- Long drying times lead to over-dried grains, increasing breakage rates, labor costs, fuel consumption, and overall drying costs.
- Once the mesh is clogged with rice husks, cleaning is difficult. During each drying season, it must be cleaned multiple times, and maintenance takes away profitable time.
- Poor-quality dried rice affects both marketability and price.
Our version
- The drive pulley features a hollow design to prevent grain crushing. With a convex profile, the belt stays aligned. Machined on a lathe for high concentricity, it uses NSK Japanese bearings for long-lasting durability.
- Grains constantly rub against the inner chute steel plates during flow. Ordinary steel wears out easily, so an additional layer of 316 stainless steel (containing nickel and manganese) is embedded in the chute, providing a smooth, wear-resistant, and durable surface.
- The dryer supports multiple heating options, including biomass hot-air furnaces, diesel burners, and more.
- Both the interior and exterior walls are treated with electrostatic powder coating, making them high-temperature resistant, wear-resistant, and corrosion-resistant, with a lifespan more than five times longer than ordinary paint.
Applications of the tower drying machine
Our new grain drying tower has a wide range of applications, which is suitable for drying rice, wheat, corn, sorghum, soybean, sunflower seed, millet, rapeseed, and other crops and grain seeds.

稻谷干燥热量与产量分析
干物质计算
- 原料进料（鲜稻谷）：20,000 kg/h
- 初始水分 w1：20%（湿基）
- 终水分 w2：12%（湿基）
干物质
进料 × (1 − w1) = 20,000 × (1 − 0.2) = 16,000 kg/h
最终产品重量
干物质 / (1 − w2) = 16,000 / (1 − 0.12) ≈ 18,182 kg/h
需蒸发的水
W = 进料 − 终产品 = 20,000 − 18,182 ≈ 1,818 kg/h
估算热需求
假设水的汽化潜热 ≈ 540 kcal/kg，系统损失 15%：Q_total = W × 540 × (1 + 0.15) ≈ 1,818 × 540 × 1.15 ≈ 1,129,000 kcal/h
对客户友好的说明
该干燥线需每小时去除约 1.82 吨水，对应约 1,129,000 kcal/h 的热量。折算为蒸汽约为每小时 2.1 吨（假设 1 kg 蒸汽 ≈ 540 kcal）。
