Packaging Machine For Nuts Grain Vertical Form Fill And Seal

The machine is designed for vertical form-fill-seal packaging of nuts and grains, integrating weighing, bag making, filling and sealing for products like peanuts, cashews, almonds, kernels and various grains.

Two models are listed: ZD-540 and ZD-730. The primary difference is the maximum film/reel width (540 mm for ZD-540 and 730 mm for ZD-730), which allows different maximum bag widths and overall machine footprint/power/weight.

Supported bag types: pillow bag, gusset bag and quad-seal bag. Lengths: up to 340 mm (standard) or up to 460 mm (extended). Width ranges: 80–200 mm (ZD-540) and 100–240 mm (ZD-730). Depth (gusset/quad dimensions) and corner size vary by model: depth typically 50–120 mm and corner 5–10 mm depending on bag type and model.

Intermittent operation with an adjustable speed of approximately 10 to 60 bags per minute. Actual throughput depends on bag size, weight per bag, product characteristics and selected weighing parameters.

The machine is equipped with a waterproof 14-head multihead weigher integrated with the vertical packer. Accuracy depends on the product, target weight and calibration; expected accuracy should be confirmed via product trials with the supplier.

Reel film width: 540 mm (ZD-540) or 730 mm (ZD-730). Reel outer diameter: up to 400 mm (ZD-540) or 500 mm (ZD-730). Reel inner/core diameter: 75 mm. Film must be heat-sealable (laminates/PE/CPP, etc.) — confirm specific film type and thickness compatibility with the supplier.

Standard electrical: 220 V / 50 Hz single phase (other specifications available per customer request). Power consumption: about 3 kW (ZD-540) or 4 kW (ZD-730). Air pressure requirement: 0.6 MPa with air consumption about 0.6 m3/min.

Safety: machine alarms and stops if there is no film, inadequate air pressure, or if safety guards are opened (guards have safety switches). Hygiene: product-contact parts are built for hygienic construction; the system supports easy cleaning and sanitary operation.

High automation: PLC control with color touch-screen HMI, automatic film position control, servo-driven film pull and horizontal sealing, automatic printing/punching/countering and unmanned operation during weighing and packing. Faults and alarms are displayed on the touch screen.

The machine is designed for quick changeovers; typical adjustments take about 10 minutes to change different pouch formats, depending on which parts need to be changed and operator experience.

Standard supply includes the multihead weigher, vertical filling packaging machine, platform and Z-type elevator. Finished-product conveyor and vibrating hopper are available/commonly used. The machine can also be integrated with upstream feeding equipment or downstream checkweighers and metal detectors.

ZD-540 footprint: approximately 1300 x 1650 x 1650 mm and weight about 1000 kg. ZD-730 footprint: approximately 1450 x 2600 x 1950 mm and weight about 1200 kg. Allow extra space for operator access, maintenance and material handling.

Routine cleaning of product-contact parts after production runs and regular inspection/lubrication of moving parts is recommended. Check and replace sealing jaws, belts and air filters as needed. Follow the supplier's maintenance schedule and safety lockout procedures.

For expected accuracy, sample testing, spare parts lists, warranty, on-site installation, training and service agreements, contact the manufacturer or authorized distributor with product samples and required bag specifications so they can provide tailored data, quotes and service options.
