Powder is the most difficult nut to crack in the packaging of agricultural inputs: light specific gravity (such as wettable powder) is easy to float, heavy specific gravity (such as compound fertilizer powder) is easy to agglomerate and bridge, and ultra-fine powder can get into the gaps in the equipment and jam the motor.
Arch breaking and bridging prevention, continuous unloading: the silo has a built-in mechanical arch breaking device + vibration assistance, specially adjusted for powders that are highly hygroscopic and easy to agglomerate. The spiral elevator feeds materials at a constant speed, eliminating the pulse-type feeding that "rushes suddenly and breaks the material", and the metering stability is directly maximized.
Servo screw measurement, accuracy ≤±1%: high-precision stepper motor drives the screw, number of rotations = blanking weight, closed-loop control. The dosage of each bag is accurate, so there will be no complaints about insufficient efficacy due to underfilling, nor a waste of raw materials due to overfilling - every gram of pesticide original drug is worth money.
Fully enclosed + dust removal interface, the workshop will not "swallow powder": the unloading channel is fully enclosed, and key workstations are equipped with dust removal interfaces, which can be directly connected to the central dust removal system or pulse bag dust collector. Dust does not leak out, PM2.5 in the workshop meets the standard, environmental inspections are carried out without guilt, and workers do not need to "eat powder" every day.
Anti-corrosion material, resistant to acid and alkali and non-corrosive: parts in contact with materials are made of 304 stainless steel or special anti-corrosion coating to resist acid and alkali components and corrosive additives in pesticide powders. The equipment life is 3-5 times longer than that of ordinary carbon steel models.
The pain point of granular fertilizer is "brittleness" - there is a big gap from the silo to the packaging machine, and the round particles turn into broken powder. Not only are nutrients lost, but the seal is also prone to leakage.
Multi-head combination scale can accurately weigh irregular particles: The 10-head/14-head electronic combination scale operates at high speed and automatically matches the optimal combination. Whether it is round urea, columnar organic fertilizer, or irregular blended fertilizer (BB fertilizer), the combination closest to the target weight can be calculated within 0.5-1 seconds, with a measurement accuracy of ±0.5%-1g.
Z-type lifting + buffering and unloading, greatly reducing the particle breaking rate: Z-type bucket elevator + vibration buffering and unloading channel, reducing the falling height and impact force of particles. The particles of organic fertilizers and water-soluble fertilizers have high integrity, the seals are not punctured, and the materials do not leak during transportation.
Rapid packaging of large sizes, full production capacity: The weight of a single package of granular fertilizer is usually large (5kg-50kg). The equipment comes standard with a large opening lower hopper + widened bag making mechanism. The packaging speed can reach 8-15 packages/minute (depending on the specification), and there are 3-4 skilled workers on one line.

Piston pump/rotor pump filling, not afraid of high viscosity: For high-viscosity materials such as water-soluble fertilizers and suspending agents, use large-diameter piston pumps or corrosion-resistant rotor pumps. The flow path of the pump body is short, there are no dead corners, it is not easy to be blocked, and the filling is smooth.
Back-sucking prevents dripping, and the bag mouth is clean and tightly sealed: the filling valve has a built-in back-sucking function, and the reverse suction is instantaneous after filling is completed, completely eliminating string dripping. There is no residual fertilizer liquid at the mouth of the bag, the seal is smooth and does not leak, and the bag will not expand or corrode the outer packaging during transportation.
316L stainless steel + Teflon coating, anti-corrosion and durable: All parts in contact with liquid are made of 316L stainless steel or lined with Teflon (PTFE) coating, which can withstand chloride ion corrosion and acid and alkali corrosion of high-concentration water-soluble fertilizers. The core pump body has a service life of millions of fillings.
Supports high-temperature filling + nitrogen filling to preserve freshness: Some liquid fertilizers need to be filled while hot (such as molten fertilizer), and the equipment supports high-temperature filling up to 95°C. Optional nitrogen filling function can replace the oxygen in the bag and delay the oxidation and precipitation of liquid fertilizer.

I really understand the "temperature" of agricultural materials: It's not just changing the material of food equipment and calling it "agricultural materials only". We have gone through the pits of powder bridging, particle fragmentation, and liquid crystallization blocking the pump. Every parameter is adjusted using real agricultural materials.
Modular combination, covering everything from small bags to ton bags: today we make 20g small bags of pesticides, tomorrow we make 25kg woven bags of compound fertilizer, and the day after tomorrow we make 1 ton bags - different specifications correspond to different modules, and the hardware is expandable, so there is no need to tear down the whole machine and start over.
Use your fertilizer/medicine test machine before leaving the factory: Before each piece of equipment leaves the factory, run it continuously for 72 hours with the real powder/granule/liquid provided by the customer to verify the anti-bridging effect, measurement accuracy, and anti-corrosion performance. Put into production directly at the factory.
Full life cycle services: free on-site survey + workshop layout design → installation and commissioning + operation training → 3-year warranty for core components → lifelong technical support + rapid supply of wearing parts.
