Fully Automatic Quantitative Packaging Scale and Vertical Granule Packaging Machine: Solving Quantitative Packaging Challenges for Materials in Multiple Industries

In food processing, chemical production, and grain storage and logistics sites, the operational stability of packaging equipment directly affects the efficiency of the entire production line. Faced with materials of different properties — from free-flowing granules to fragile flakes, from food-grade requirements to chemical corrosion resistance — a reliable automatic quantitative packaging scale, a highly adaptable vertical granule packaging machine, or a professional grain quantitative packaging scale system is critical to ensuring continuous production. How to select the right equipment based on material type is a question many production managers consider.

Matching Packaging Equipment to Material Types

Food materials impose high requirements on hygiene level and precision of packaging equipment.

Automatic quantitative packaging scales and vertical granule packaging machines are widely suitable for: rice, millet, black rice, glutinous rice, brown rice, corn grits, various beans (soybean, mung bean, red bean, black bean, broad bean, pea, kidney bean), peanut, sunflower seed, pumpkin seed, walnut, almond, pistachio, hazelnut, pine nut, pecan, macadamia nut, cashew, melon seeds, candy, chocolate, preserved fruit, raisin, red date, puffed food, potato chips, rice crackers, popcorn, cereal, oatmeal, mixed oatmeal, seasoning, salt, monosodium glutamate, chicken bouillon, white sugar, rock sugar, brown sugar, coffee bean, tea (black tea, green tea, white tea, oolong tea, dark tea, Pu’er tea, scented tea), baby food, dried mushroom, meal replacement porridge, frozen food (frozen dumpling, glutinous rice ball, meatball, shrimp, popcorn chicken), dried tofu product, seafood product, pickled vegetable, dried vegetable, dried fruit, etc.

Parts in contact with materials are made of food-grade stainless steel, compliant with GMP and HACCP standards, effectively avoiding secondary contamination.

Chemical and rubber & plastic materials are often corrosive or have large differences in flowability.

Automatic quantitative packaging scales can handle: plastic pellets (PE, PP, PVC, ABS, EVA, PET), resin granules, fertilizer granules (compound fertilizer, organic fertilizer, urea, potash fertilizer, phosphate fertilizer, controlled-release fertilizer, water-soluble fertilizer), pesticide granules, laundry powder, laundry capsule, soap powder, cleaning granules, hardware (screw, bolt, nut, gasket), plastic parts, electronic components, etc.

For chemical dusty environments, the equipment is equipped with explosion-proof interfaces and reinforced sealing. The weighing sensor features automatic zero-tracking to adapt to complex working conditions.

Grain materials have prominent demands for continuous operation and weather resistance of packaging equipment.

Grain quantitative packaging scales are specially designed for paddy, indica rice, japonica rice, glutinous rice, wheat, corn, soybean, sorghum, barley, oat, buckwheat, millet, coix seed, sesame, rapeseed, cottonseed, sunflower seed, peanut, and various grain seeds, commercial grain, feed grain, industrial grain, etc.

The system is fitted with a dust removal port and anti-corrosion treatment, adapting to dust and temperature/humidity variations in grain storage environments.

Feed and pet food materials feature large packaging volumes and diverse varieties.

Equipment can process: pet food (dog food, cat food), fish feed, shrimp feed, chicken feed, pig feed, feed granules, cat litter, etc.

Vertical granule packaging machines achieve integrated operation from bag making to sealing, supporting fast switching of multiple bag styles.

Other materials such as Chinese herbal pieces, tablets, and various seeds have special requirements for packaging accuracy and bag appearance.

Marchi equipment can meet these demands by adjusting feeding methods and sealing parameters.

Marchi Dual Bases: Professional Collaboration Between Guangzhou and Hefei

Among many packaging equipment manufacturers, Marchi Packaging Equipment Co., Ltd. has formed a north-south service network with respective focuses through its two bases in Guangzhou and Hefei.

Guangzhou Marchi Packaging Equipment Co., Ltd. is rooted in South China, with rich experience in food, pharmaceutical and daily chemical industries.

Its R&D team has an in-depth understanding of vertical granule packaging machines and has made multiple optimizations in feeding mode, bag adaptability, sealing temperature control, etc., according to different food material characteristics.

For instance, a vibration feeding system with drop buffer is adopted for fragile puffed food; a low-temperature resistant sealing device is developed for frozen food.

Guangzhou Marchi excels in whole-line integration, capable of seamlessly connecting packaging machines with front-end lifting, rear-end checkweighing, metal detection and palletizing equipment, providing coherent services from planning to implementation.

High-quality brands are selected for control components. Pneumatic control is used for transverse and longitudinal sealing, ensuring stable and reliable action.

Hefei Marchi Packaging Equipment Co., Ltd. is based in the Yangtze River Delta, with outstanding performance in automatic quantitative packaging scales and grain quantitative packaging scales.

The R&D team continuously iterates weighing algorithms. Through multi-stage feeding and real-time drop compensation, the equipment maintains a measurement accuracy of ±0.2%～0.5% under continuous high-intensity operation.

Adopting PLC control, the equipment integrates weight display, packaging sequence, process interlocking and fault alarm. Independent windows for packaging weight input and weighing display allow operators to monitor packaging weight, cumulative output and bag count in real time.

Hefei Marchi equipment is widely used in grain, agricultural and chemical industries. The structural design emphasizes durability, and key components are selected from premium brands to adapt to continuous production.

In the field of granular material packaging, the value of equipment is ultimately reflected in stable, accurate and efficient on-site problem-solving.

Relying on their respective technical strengths and service networks, Guangzhou Marchi and Hefei Marchi Packaging Equipment Co., Ltd. are committed to providing practical automated packaging solutions for enterprises of different industries and scales.
