By introducing advanced technology and cooperating with agricultural machinery experts, Shuliy has developed and produced the low-temperature circulating mixed flow cereal dryer<\/strong>, also called the tower drying machine. <\/p>

This type of product has adopted a Siemens<\/a> PLC automatic intelligent control system<\/strong> and is equipped with a variety of heat source solutions, which have low power, low heat consumption, fast moisture discharge, and low crushing rate.<\/p>

This tower dryer comes in two models: 5HXG-15<\/strong> and 5HXG-32<\/strong>. Maximum capacities: corn 3,400\u202fkg\/h, wheat 3,250\u202fkg\/h, rice 3,500\u202fkg\/h, rapeseed 2,600\u202fkg\/h<\/strong>.<\/p>

The cereal dryer also has a wide range of applications, especially suitable for granular grains such as corn, rice, soybeans,<\/strong> rapeseed<\/strong>, 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!<\/p>

Principle of the mixed flow cereal dryer<\/h2>

When the grain drying tower begins to load grain, the grain in the hopper is lifted to the top of the main silo by the elevator, and then the grain is sent into the drying box through the upper auger until it is full.<\/p>

During drying, the grain emissions continuously discharge the grains at the bottom of the drying section to the lower agitator, the lower agitator sends the grains to the elevator to be lifted to the upper agitator, and the upper agitator sends the grains to the tempering zones. Under the gravity of itself, the grains in the tempering zones slowly move from top to bottom to the four drying sections.<\/p>

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. <\/p> <\/div>

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.<\/p> <\/div> <\/div>

Composition of the mixed flow cereal dryer<\/h2>
\"Different<\/figure>

Two different bases for different materials<\/h3>

The gravity-fed base eliminates the screw conveyor, reducing grain breakage caused by collisions with conveyor blades, making it suitable for drying larger grains.<\/p>

The internal structure of the drying section<\/h3>

The inside of the drying box is made of 316<\/strong>\u00a0stainless steel, galvanized sheet, and a thick steel plate.<\/p> <\/div>

Elevator, conveyor belt, and bucket<\/h3>

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.<\/p> <\/div><\/div>

Siemens PLC automatic control system<\/h3>

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.<\/p> <\/div>

Advantages of the mixed flow grain dryer<\/h2>
  • Low application power:<\/strong> 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.<\/li>
  • High drying efficiency:<\/strong> Intelligent drying technology is adopted to automatically adjust the drying temperature and time to meet the requirements of different humidity grains. Low-temperature drying makes the grain evenly heated, with a low burst rate and high germination rate. After drying, the grain particles are complete to ensure the quality of the grain.<\/li>
  • Low heat and energy consumption:<\/strong> The dryer adopts low temperature and constant temperature and uses the clean energy of heat exchange gas to fully cover and dry without dead ends, with no secondary pollution. The performance is stable, and the moisture of the drying is consistent between the surface and the inside, so that the grain will not be mildewed, easy to store for a long time.<\/li>
  • Long service life:<\/strong> 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).<\/li>
  • Low drying cost:<\/strong> Our new type of dryer adopts angled air intake, has the advantages of smooth ventilation, even drying, and no need to clean up all year round.<\/li> <\/ul>

    Heat source options for mixed flow cereal dryer<\/h2>

    Biomass hot air furnace<\/h3>

    Can burn coal, biomass, wood, straw, etc. The heat exchanger is made of S310 high-temperature stainless steel and 20 manganese steel. It keeps grains from changing color, mixing flavors, or producing burnt particles.<\/p>

    \"Biomass
    Biomass Hot Air Furnace<\/figcaption><\/figure> <\/div>

    Diesel furnace<\/h3>

    Uses diesel as fuel. Heat is stable and strong, suitable for continuous drying.<\/p>

    Natural gas burner<\/h3>

    Uses natural gas as fuel. Clean and efficient combustion, safe and smoke-free.<\/p>

    Electric burner<\/h3>

    Uses electricity as energy. Precise temperature control, easy to operate, and environmentally friendly.<\/p>

    Why choose our low-temperature circulating tower drying machine\uff1f<\/h2>

    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.<\/p>

    Standard version vs. Our version<\/h3>

    Standard version<\/h4>
    • The oldest type of dryer has a simple design, high power consumption, high energy use, and is prone to fire.<\/li>
    • 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.<\/li>
    • Common mesh plates and cross-flow dryers often get clogged by rice husks.<\/li> <\/ul> <\/div>
      • Long drying times lead to over-dried grains, increasing breakage rates, labor costs, fuel consumption, and overall drying costs.<\/li>
      • 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.<\/li>
      • Poor-quality dried rice affects both marketability and price.<\/li> <\/ul> <\/div> <\/div>

        Our version<\/h4>
        • 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 <\/strong>Japanese bearings for long-lasting durability.<\/li>
        • Grains constantly rub against the inner chute steel plates during flow. Ordinary steel wears out easily, so an additional layer of 316 stainless steel<\/strong> (containing nickel and manganese) is embedded in the chute, providing a smooth, wear-resistant, and durable surface.<\/li> <\/ul> <\/div>
          • The dryer supports multiple heating options, including biomass hot-air furnaces, diesel burners, and more.<\/li>
          • 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.<\/li> <\/ul> <\/div> <\/div>
