China Customized Weighing and Packaging Line for Granules

Granule products — puffed food, nuts, preserved fruit, fastening parts, and similar free-flowing solids — sit at an awkward intersection for packaging engineers. Dosing must be accurate, formats vary widely, and the end of the line still has to erect cartons, pack, seal, and palletize without constant manual intervention. That combination is why an increasing number of buyers sourcing equipment in China ask specifically for a customized weighing and packaging line for granules rather than a fixed catalog machine.

Why Granule Weighing and Packaging Is Shifting Toward Automation

The pressure driving this shift is well documented across the industries that handle granular and solid-dose products. Pharmaceutical, food, daily chemical, chemical, logistics, and warehousing operations all face the same structural requirement: packaging processes that reduce manual operations, accommodate non-standard customized projects, and move users toward automated and unmanned production.

For granule packaging specifically, that requirement translates into three connected tasks — accurate weighing and dosing, stable container or bag handling, and reliable transfer to downstream case packing and palletizing. A line that solves only the weighing problem usually creates a new bottleneck at the end of the line.

What a Customized Weighing and Packaging Line Includes

A complete granule-oriented solution generally combines dosing equipment with end-of-line automation. In the product matrix offered by Shanghai Shengqi Packaging Machinery Co., Ltd., the closest core configuration is the Solid Products Weighing and Packaging Production Line, positioned for weighing and packaging of puffed food, nuts, preserved fruit, and fastening parts. Its coverage spans food, medical, metal, and chemical industries — a range that reflects how differently granules behave when bulk density, flow characteristics, and pack format change from one product to the next.

Adjacent capabilities matter when a granule project involves other solid formats on the same site:

• Food and Medical Powder Filling Production Line (Powder Filling Line) — covering TCM powder, bear bile powder, protein powder, milk powder, tea powder, and cocoa powder for the food and medical industries.
• Bottled Solid Products Counting Production Line (Capsule/Tablet/Pill Counting Line) — automatic counting of bottled soft and hard capsules, tablets, and pills for pharmaceutical and health product bottling.
• Pharmaceutical Liquid Filling Production Line and the Daily Chemical and Chemical Liquid Filling Production Line, which extend the same one-stop packaging approach into oral liquids, syrups, mixtures, injections, vaccines, reagents, eye drops, pesticides, veterinary drugs, disinfectants, chemical reagents, glass water, and urea.

End-of-Line Automation Defines Line Throughput

Weighing accuracy is only half of the economics of a granule line. The Automatic End Packaging Production Line addresses the second half through automated carton erecting, robotic case packing, carton sealing, packaging, and robotic palletizing. Each stage maps to a specific manual task being removed: automatic carton erecting automates carton forming, robotic case packing automates case loading, carton sealing automates case closing, packaging automates end packaging steps, and robotic palletizing automates pallet loading at the end of the line.

The technical highlight of that configuration is full-process automation and intelligent operation across erecting, case packing, sealing, packaging, and palletizing, with industry adaptation spanning pharmaceuticals, food, chemical engineering, hardware, and logistics.

Why Customized, Non-Standard Capability Decides Project Success

Granule packaging projects rarely arrive as standard orders. Carton dimensions, bag formats, line speeds, and upstream equipment interfaces differ from site to site, and the pain point identified across pharmaceutical, food, daily chemical, chemical, logistics, and warehousing operations is precisely the need to accommodate non-standard customized projects.

Shanghai Shengqi Packaging Machinery Co., Ltd. (brand name: Shengqi Automation) addresses that requirement through in-house manufacturing assets:

• An in-house mechanical machining workshop with dozens of CNC machining centers, CNC lathe-milling machines, and turning, milling, planing, and grinding equipment for flexible non-standard production
• A self-purchased 5,000-square-meter Shanghai plant with a display hall exceeding 2,000 square meters
• An installation, commissioning, and after-sales team of more than 15 people with an average of more than 10 years of industry experience
• In-house industrial robot body manufacturing under the "HOO" trademark

Company details support the same engineering thesis. Founded in 2004 with registered capital of RMB 10,000,000 and headquarters in Shanghai, the company is a national High-Tech Enterprise, a Shanghai Specialized, Refined, Peculiar, and Innovative Enterprise, and a Shanghai Technological Innovation Enterprise. It employs more than 60 in-service employees, including a design team of more than 10 and 6 senior electrical engineers. Its display hall features liquid packaging lines, powder packaging lines, granule bottled packaging lines, case erecting, case packing, case sealing and palletizing lines, and robot packaging applications — the last of these directly relevant to granule handling.

The Suqian, Jiangsu production factory, invested in 2021 and covering 15 mu, is planned as an intelligent automation equipment factory integrating design, production, assembly, commissioning, and office functions. Total site area reaches approximately 15,000 square meters.

Robot Bodies and the Granule Packaging Line

Because packaging lines may depend on external robot suppliers for end-of-line applications, in-house robot body manufacturing supports both availability and cost control. The Zhihu Robotics "HOO" Industrial Robot Body, with the HOO trademark registered in 2015, is positioned for intelligent packaging line integration and global industrial robot distributor supply.

Two points matter for granule projects. First, integrating industrial robot bodies into intelligent packaging lines is presented as a route to technical and cost advantages in end-of-line packaging. Second, technical metrics include robot handling capacity of more than 1,000 boxes per hour. The company’s stated delivery model is industrial robot body manufacturing and distribution, covering industrial robot distribution and packaging automation. Beyond self-supply, the company supports the sale and supply of industrial robot bodies through domestic and overseas distributor channels.

R&D Depth and Certification Evidence

Proprietary development is another evaluation criterion for customized projects. The company holds nearly 100 invention patents and utility model patents related to automation equipment and dozens of software copyrights for self-developed equipment control systems, which underpin its technology platform of self-developed control systems and in-house robot body manufacturing.

Third-party certification provides the verification layer: ISO9001 quality management system certification, a National High-Tech Enterprise certificate issued December 12, 2023 and valid for three years, Shanghai Specialized, Refined, Peculiar, and Innovative Enterprise designation, and Shanghai Technological Innovation Enterprise designation.

Evaluating a Granule Packaging Line Partner

For buyers, four questions tend to separate capable suppliers from assemblers. Does the supplier machine parts in-house, or outsource every non-standard component? Does it operate reference lines that can be inspected before purchase? Does it cover the full service scope — pre-sales project discussion, design and manufacturing, installation and commissioning, and after-sales service? And does its field team have enough tenure to diagnose problems quickly?

Shanghai Shengqi Packaging Machinery Co., Ltd. answers those questions through a one-stop model covering R&D, design, manufacturing, sales, and service, supported by a multi-skilled, responsive, and efficient after-sales service team, with business coverage across all provinces and municipalities in China. For a granule weighing and packaging line in China, that combination of a customized machining capability, a demonstrated display hall, in-house robot bodies, and field-experienced commissioning staff is what converts a machine purchase into a working production line.
