The DCS-5U is a fully automatic bagging and weighing machine engineered for high-speed, continuous grain packaging operations. Designed to automate the complete packaging cycle — from bag feeding and weighing to filling, sealing, and conveying — the DCS-5U delivers measurable gains in throughput, weight accuracy, and labor efficiency across agricultural, feed, and industrial processing environments.

With a rated capacity of up to 600 bags per hour, this system is suited for large-scale operations packaging rice, wheat, corn, pulses, animal feed, granular fertilizers, and similar free-flowing bulk materials in pre-formed paper or plastic bags.

What the DCS-5U Does

The DCS-5U integrates every stage of the open-mouth bagging process into a single automated line. Operators load empty bags into the feeder magazine; the machine takes over from there, handling bag extraction, opening, clamping, filling, settling, conveying, and sealing without manual intervention at each stage.

This level of automation removes the most labor-intensive steps from grain packaging lines, reduces per-bag handling errors, and sustains consistent output even during extended production runs.

System Workflow — Step by Step

1. Automatic Bag Feeding: The bag magazine stores approximately 200 empty bags. An automatic disc-switching mechanism ensures continuous supply without halting the line when one stack depletes.
2. Vacuum Bag Extraction: Each empty bag is individually extracted using precision vacuum suction, ensuring clean, jam-free separation even with paper bags and lightweight plastic films.
3. Bag Opening and Clamping: Once extracted, dedicated bag clamps open the mouth and hold it firmly in position for accurate insertion into the filling station.
4. Transition Hopper: A purpose-built hopper connects the upstream metering device to the filling spout, managing product flow and preventing spillage during the fill cycle.
5. Fill and Tapping: The bag receives a measured fill of 10 to 20 kg per cycle. A bag bottom tapping device activates after filling to settle the material, ensuring the bag sits flat and weighs correctly.
6. Horizontal and Vertical Conveying: Filled bags are transferred from the filling station to the sealing unit via an integrated conveyor system designed to handle varying bag heights and production line layouts.
7. Transition Conveyor: A flexible transition conveyor docks smoothly with downstream equipment — palletizers, checkweighers, label applicators — regardless of height differences.
8. Bag Sealing: The machine applies the appropriate seal type based on bag material. Paper bags are closed by sewing, hot melt adhesive, or wrinkled paper sealing. Plastic bags are sealed using thermosetting (heat sealing).

Key Performance Advantages

• High throughput with low labor demand. At up to 600 bags per hour, the DCS-5U replaces multiple manual operators while delivering consistent output around the clock.
• Accurate net weight per bag. Integrated weighing and controlled fill cycles maintain tight weight tolerances, reducing product giveaway and ensuring compliance with commercial weight standards.
• Versatile bag material compatibility. Supports both paper bags and plastic bags across a practical range of film thicknesses, giving processors flexibility to use standard supply-chain bag formats.
• Continuous automatic bag feeding. The dual-disc feeder magazine switches automatically, keeping the line running without a manual reload stop between stacks.
• Multiple sealing methods in one machine. Sewing, hot melt, and thermosetting sealing options are available on a single platform, accommodating paper and plastic bag formats without requiring a separate sealing unit.
• Robust industrial construction. Heavy-duty steel frame, pneumatic bag handling, and a vacuum extraction system are built for sustained operation in grain mills, feed plants, and packaging facilities.
• Smooth downstream integration. The transition conveyor and adjustable-height docking design connect cleanly to existing equipment on mixed-height production lines.

Supported Materials and Industries

The DCS-5U is validated for use with the following product categories:

Grains and Cereals Rice, wheat, maize (corn), sorghum, barley, oats, pulses (lentils, chickpeas, mung beans)

Animal Feed and Aquafeed Pelleted feed, crumbled feed, mixed grain rations, compound feed, fish feed pellets

Agricultural Seeds Cereal seeds, pulse seeds, oil crop seeds, grass seeds

Fertilizers and Agrochemicals Granular NPK fertilizer, urea granules, granular micronutrients, granular pesticide carriers

Industrial Bulk Granules Plastic pellets, granular chemicals, granular construction additives

Bag Format and Size Range

The DCS-5U handles pre-formed open-mouth bags across a defined dimensional range, accommodating standard commercial grain and feed bag formats:

• Length: 580 to 640 mm
• Width: 300 to 420 mm
• Bottom gusset: 75 mm
• Fill weight: 10 to 20 kg per bag
• Plastic film thickness: 0.18 to 0.25 mm

This range covers the most commonly used 10 kg, 15 kg, and 20 kg consumer and trade bag formats for rice, flour, and animal feed.

Integration and Installation Considerations

The DCS-5U is designed as a standalone packaging unit that can be positioned at the discharge point of a grain handling or processing line. The machine requires a compressed air supply at 750 NL/min and a 3 kW electrical connection.

The transition conveyor at the discharge end is height-adjustable to align with checkweigher tables, bag-labeling stations, automated palletizers, or manual stacking areas — reducing the need for custom mechanical fabrication when integrating into an existing packaging line.

For operations handling multiple product types or bag sizes, the machine’s adjustable bag clamp and filling settings allow quick format changeovers between production runs.

Frequently Asked Questions

What is the minimum and maximum fill weight for the DCS-5U?

The DCS-5U fills bags in the range of 10 to 20 kg per cycle, which covers standard commercial grain bag sizes.

What bag materials does the DCS-5U support?

그리고 machine is compatible with pre-formed paper bags and plastic bags with a film thickness of 0.18 to 0.25 mm. Both bag types are handled using the same automatic bag feeder.

What sealing methods are available?

Paper bags can be sealed by stitching (sewing), hot melt adhesive, or wrinkled paper fold. Plastic bags are sealed using thermosetting (heat sealing).

Can the DCS-5U handle animal feed pellets and granular fertilizer?

Yes. The system is designed for free-flowing granular materials including grain, pelleted feed, and granular chemicals, provided the material flows cleanly through the filling spout.

How does the machine maintain bag weight accuracy?

Fill accuracy is maintained through a controlled metering and fill cycle, with the bag bottom tapping device settling material before the bag is released to the conveyor, reducing void space variation that can affect net weight.
