By introducing advanced technology and cooperating with agricultural machinery experts, Shuliy has developed and produced the low-temperature circulating mixed flow cereal dryer, also called the tower drying machine.
This type of product has adopted a Siemens PLC automatic intelligent control system and is equipped with a variety of heat source solutions, which have low power, low heat consumption, fast moisture discharge, and low crushing rate.
This tower dryer comes in two models: 5HXG-15 and 5HXG-32. Maximum capacities: corn 3,400 kg/h, wheat 3,250 kg/h, rice 3,500 kg/h, rapeseed 2,600 kg/h.
The cereal dryer also has a wide range of applications, especially suitable for granular grains such as corn, rice, soybeans, rapeseed, etc. Currently, our fourth generation is the most advanced cereal drying machine in the world; it is a revolution in grain machines and will bring huge gains for grain harvest!
Principle of the mixed flow cereal dryer
Wenn der Getreidetrocknungsturm beginnt, Getreide zu laden, wird das Getreide im Trichter durch den Elevator auf die Oberseite des Hauptsilos gehoben und dann wird das Getreide durch die obere Schnecke in den Trocknungskasten geleitet, bis dieser voll ist.
Während des Trocknens entladen die Getreideemissionen die Körner am Boden des Trocknungsbereichs kontinuierlich zum unteren Rührwerk. Das untere Rührwerk schickt die Körner zum Elevator, wo sie zum oberen Rührwerk gehoben werden, und das obere Rührwerk schickt die Körner zu den Temperierzonen . Aufgrund der Schwerkraft bewegen sich die Körner in den Temperierzonen langsam von oben nach unten zu den vier Trocknungsabschnitten.
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.
Die interne Struktur des Trocknungsabschnitts
The inside of the drying box is made of 316 stainless steel, galvanized sheet, and a thick steel plate.
Elevator, conveyor belt, and bucket
The hoist conveyor belt is made of a pure nylon canvas belt. The bucket is made of virgin nylon plastic with good toughness and no brittleness.
Siemens PLC automatic control system
The fully automatic control system, using the touch screen, is easy to operate, equipped with a fault location display system, and can automatically measure the moisture, and automatically stop when the set value is reached.
Umweltfreundlicher und energiesparender Heißluftofen
The stove uses biomass as a heat source, which can burn tree branches and rice chaff, and can also be transformed into burning oil and gas.
Entfeuchtungs- und Abluftventilator
Leiten Sie die heiße Luft durch den Trocknungsbereich und lassen Sie die heiße Luft mit Feuchtigkeit abfließen.
Vorteile des Getreidetrockners mit Mischstrom
- 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.
- Hohe Trocknungseffizienz: Intelligente Trocknungstechnologie wird übernommen, um die Trocknungstemperatur und -zeit automatisch anzupassen, um die Anforderungen unterschiedlicher Feuchtigkeitsgrade von Getreide zu erfüllen. Die Tieftemperaturtrocknung sorgt für eine gleichmäßige Erwärmung des Getreides mit einer niedrigen Bruchrate und einer hohen Keimrate. Nach dem Trocknen sind die Getreidekörner vollständig, um die Qualität des Getreides zu gewährleisten.
- Geringer Wärme- und Energieverbrauch: Der Trockner arbeitet bei niedriger und konstanter Temperatur und nutzt die saubere Energie des Wärmetauschergases, um ohne Sackgassen vollständig und gleichmäßig zu trocknen, ohne sekundäre Verschmutzung. Die Leistung ist stabil und die Feuchtigkeit des Trocknungsgutes ist zwischen Oberfläche und Innerem konsistent, sodass das Getreide nicht schimmelt und lange gelagert werden kann.
- 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).
- Niedrige Trocknungskosten: Unser neuer Trocknertyp verfügt über einen schrägen Lufteinlass mit den Vorteilen einer reibungslosen Belüftung, einer gleichmäßigen Trocknung und keiner Notwendigkeit, das Gerät das ganze Jahr über zu reinigen.
Heat source options for mixed flow cereal dryer
Why choose our low-temperature circulating tower drying machine？
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.
