Complete Feed Bag Filling Machine in Pakistan

One packing point, several different feeds

The mill handles complete poultry feeds as cooled broiler pellets approximately 3–4 mm in diameter, screened crumbles and layer mash. It also packs dairy concentrate mash for feeding alongside forage. Maize, wheat bran, rice polishings, soybean meal and cottonseed meal contribute different particle shapes, dust levels and bulk densities.

Dry pellets can discharge freely, while bran-rich mash may bridge or arrive unevenly. That makes feeding method a procurement decision. For a shared outlet handling both forms, the DCS-50P belt-fed model Automatic Packing Machine is the candidate. Gravity-fed DCS-50K selection would require a pellet-only duty or separate confirmation of material suitability.

The sample acceptance plan starts with dry products at approximately 11–13% moisture on a wet basis. Supplier trials should include the dustiest mash and the least free-flowing routine formula. Wet, sticky material would require another assessment.

Count the bags behind the annual tonnage

For this application, poultry products use 50 kg open-mouth woven polypropylene bags and dairy concentrate uses 40 kg bags. The planning split is 70% of annual tonnage in 50 kg bags and 30% in 40 kg bags. Bag dimensions, fabric and sewing headspace are checked with filled samples.

The calculation gives 350,000 poultry bags and 187,500 dairy bags: 537,500 bags annually. Over 300 operating days, that averages approximately 1,792 bags per day. Seven productive packing hours require about 256 completed bags per hour.

A provisional acceptance target of five completed bags per minute would provide 2,100 bags across seven productive hours. The full-shift trial must demonstrate that rate with the chosen products, bag weights and downstream handling. The published machine cycle is a separate reference.

Make weighing and product flow work together

The belt feeder needs controlled coarse and fine dosing settings for each product. Material still falling after cut-off affects the final weight, so a pellet setting should not be assumed suitable for a dusty mash. Hopper level and product flow should remain reasonably consistent during acceptance tests.

Bag dimensions also matter. At an illustrative loose bulk density of 400 kg/m³, a 50 kg fill occupies 125 litres before allowing sewing headspace. A bag selected only by nominal weight may be too small for a lighter mash.

The inlet bin, transition chute and dust extraction connection need review together. Dust capture should contain emissions without pulling on the weighing assembly. Flexible connections and separation from conveyor vibration help the scale settle consistently.

The bin review also checks usable buffer volume and residual feed above the weigh hopper. Low-level alarms can distinguish an empty supply bin from a dosing fault. Bagging trials should include both a full bin and its normal low operating level, because feed pressure can affect flow.

Product changes require clearing retained feed from the hopper, belt and discharge path. Layer and dairy recipes need identification checks before packing restarts. The controls should store product-specific settings, with verification bags checked after each changeover.

Agree what the accuracy figure actually means

The purchase contract should define whether percentage error refers to target fill weight or another reference, together with the test load, operating speed and sampling method. If ±0.2% is explicitly defined against a 50 kg target, it corresponds to ±100 g. A catalogue percentage alone does not establish a tighter gram-level guarantee.

Commissioning records should include individual bag errors and the average bias for each product. An independent reference scale checks net feed weight after accounting for bag tare. Routine checks should follow an agreed schedule and restart after maintenance or a suspected drift.

Average overfill deserves separate attention. A hypothetical positive bias of 20 g across 537,500 bags would represent 10,750 kg of feed annually. Bias is therefore tracked separately from individual bag errors during the weighing assessment.

Keep the staffing brief tied to the whole station

The proposed arrangement uses one operator presenting bags and another guiding them through closure. The interface plan includes mechanical bag-handling assistance at the warehouse end, with pallet clearance coordinated by warehouse staff. Its capacity and availability are included in the staffing assessment.

The line trial therefore includes bag placement, filling, conveyor transfer, sewing, pallet clearance and ordinary interruptions. The crew requirement can be confirmed only after those operations are observed together. A faster filler cannot compensate for a slower sewing head or blocked discharge.

The interface survey records bin outlet height, bag-clamp access, conveyor elevation and maintenance clearance. Electrical design provisionally uses 400 V, three-phase, 50 Hz, confirmed against the site panel. Compressed air must maintain the specified pressure during simultaneous plant demand.

Delivery planning can assess Qingdao to Karachi and onward transport to Punjab. The quotation should identify included weighing, belt feeding, controls and closure components, plus installation assistance and spare parts. The spares list should cover clamp seals, pneumatic components and sewing consumables by specification.

For a complete feed bag filling machine in Pakistan, send RICHI Machinery samples of each feed form, bag specifications and a dispatch breakdown by bag weight. Add photographs of the existing sewing and pallet-handling area. Those details allow the proposal to address finished dispatch capacity and staffing together.
