At present, competition in the fertilizer industry is increasingly fierce, and the efficiency and precision of packaging links directly affect enterprises' production costs and market response speed. Especially for products such as amino acid fertilizers and amino acid water-soluble fertilizers, higher requirements are imposed on metering accuracy, bag mouth tightness and full-line continuous operation capacity in the packaging process. As an original manufacturer with 27 years of industrial experience, Marchi Packaging Equipment launches the fully automatic amino acid fertilizer packaging unit (equipment model: MCZD-25K), and provides practical and feasible automatic packaging solutions for fertilizer manufacturers nationwide with stable and reliable performance.

Equipment Structure and Core Performance
The MCZD-25K fully automatic packaging unit integrates automatic weighing, automatic bag loading, automatic filling, automatic sealing and automatic bag delivery. The whole machine consists of a bag storage bin, bag picking and sorting device, bag loading manipulator, bag clamping and discharging device, bag pushing mechanism, bag mouth guiding device, vacuum system and electric control system. The weighing link adopts a vertical screw feeding structure directly driven by a servo motor, and the weighing controller collects signals in real time and adjusts the feeding speed to ensure stable metering accuracy. The maximum packaging capacity of the equipment is 4～6 bags per minute, with a filling weight range of 10～25 kilograms per bag. It is compatible with various bag materials including paper bags, plastic bags and woven bags, with applicable bag sizes of 600～1100 millimeters in length and 300～600 millimeters in width. The total air consumption of the machine is 750 standard liters per minute, and the total power is 3 kilowatts.
Safety Design and Durability Guarantee
The whole equipment adopts a fully enclosed structure, and each execution unit is equipped with independent control and safety protection devices. Safety interlock functions such as door opening detection ensure personnel operation safety during operation. In view of the certain corrosiveness of amino acid water-soluble fertilizer, all parts in contact with materials are made of 304 stainless steel to effectively resist material corrosion and extend the service life of the equipment. Meanwhile, the equipment has the capacity of automatic continuous operation, reducing the frequency of manual intervention and lowering the labor intensity of operators.
Applicable Materials and Coverage Areas
This packaging unit is applicable to the packaging of various fertilizer and additive products, including granular and powdery fertilizers such as amino acid fertilizer, amino acid water-soluble fertilizer, compound fertilizer, organic fertilizer, biological bacterial fertilizer, humic acid fertilizer, alginic acid fertilizer, slow-release fertilizer, controlled-release fertilizer, nitro compound fertilizer, sulfur-based compound fertilizer, urea, diammonium phosphate, monoammonium phosphate, potassium chloride, potassium sulfate, potassium nitrate, calcium ammonium nitrate, ammonium sulfate, superphosphate and calcium magnesium phosphate fertilizer. It can also package feed additives and nutritional raw materials including lysine, threonine, methionine, tryptophan, arginine, glutamine, proline, compound amino acid powder, protein powder, yeast powder, vitamin premix and mineral premix.
Marchi has established a complete service system nationwide, covering provinces, municipalities and autonomous regions including Guangdong, Fujian, Jiangxi, Hunan, Hubei, Henan, Hebei, Shandong, Shanxi, Shaanxi, Gansu, Sichuan, Chongqing, Yunnan, Guizhou, Guangxi, Anhui, Jiangsu, Zhejiang, Shanghai, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Inner Mongolia, Xinjiang, Ningxia, Qinghai and Tibet, providing customers with full-cycle services ranging from scheme design, equipment manufacturing, installation and commissioning to after-sales maintenance.
Fully Automatic Packaging Process Flow
The complete packaging process of this unit is as follows: After operators manually put stacks of empty bags into the bag storage bin, the equipment automatically separates single bags and conveys them to the bag picking station; the bag sorting device performs centering positioning and pre-opening of bags; the bag loading manipulator accurately sleeves the bag mouth onto the bag clamping device of the discharging port and clamps tightly; after the weighing system completes material metering, materials are filled into bags, and a vibrating compacting device is installed during filling to improve material density; bag mouths of filled bags are sorted and sent to the sealing unit, and heat sealing or stitching is selected according to bag material types to complete sealing; finished bags are conveyed to weight re-inspection and metal detection links via conveyor belts to eliminate unqualified products; finally, qualified finished products are automatically stacked on pallets by the palletizer according to the set arrangement mode, completing the automatic operation of the whole packaging line.
Common Customer Problems and Solutions
Frequent bag type replacement leads to long equipment adjustment time. Marchi equipment is equipped with a quick adjustment mechanism, and parameters of common bag types can be pre-stored in the control system. During replacement, users only need to call the formula and finely adjust the limit, with short overall switching time and effectively reduced shutdown waiting.
Corrosiveness of water-soluble fertilizer affects equipment stability. All material contact parts of the equipment are made of 304 stainless steel, and key electrical components are sealed and protected, adapting to high-humidity and dusty environments and ensuring long-term reliable operation.
Lack of automatic palletizing in the rear packaging section still requires manual handling. Marchi has full-line integration capacity and can provide matching robotic palletizing systems to realize full-process automation from bag feeding, weighing, filling and sealing to palletizing, reducing manual handling links.
Unstable sealing quality leads to material leakage problems. The temperature and pressure of the sealing unit are adjustable to adapt to the characteristics of different bag materials, and photoelectric monitoring ensures firm and reliable sealing of each bag.
Marchi Packaging Equipment always adheres to independent R&D and original manufacturing, and is committed to providing cost-effective automatic packaging solutions for fertilizer manufacturers nationwide. Customers from all regions are welcome to visit and conduct trial tests with materials, and jointly explore packaging process paths suitable for your product characteristics.
