Introduction to 25 Kg Bag Packing Machine Manufacturer
A 25 Kg Bag Packing Machine is engineered to fill and seal 25-kilogram open-mouth or valve bags with powders and granules at high speed and with precise accuracy. Ideal for food grains, flour, sugar, chemicals, fertilizers, minerals, and animal feed, the machine integrates intelligent weighing, dust-controlled filling, and stitching/sealing for clean, consistent output. Samirika Industries Pvt. Ltd. manufactures robust, microprocessor-controlled systems that deliver repeatable weights, low product giveaway, and seamless line integration—boosting OEE and reducing operating costs.
Working Principle and Process Flow of 25 Kg Bag Packing Machine
The operator (or auto bag placer) positions an empty 25 kg bag on the filling spout. Based on product characteristics, the system uses gravity, belt, or screw feed with coarse–fine dosing. A load-cell platform or suspended weigher tracks live weight; as the target approaches, the PLC switches to fine feed for tight tolerance. Once the set-point is reached, filling stops automatically, the bag clamps release, and the bag is transferred to a sewing/sealing station via conveyor. Optional metal detection, checkweighing, print & apply labeling, and palletizing complete an end-to-end packaging cell.
Types of 25 Kg Bag Packing Machines
- Gravity Feed Weigher – For free-flowing products: rice, sugar, salt, pellets.
- Belt Feed Weigher – For semi-free-flow materials: fertilizers, granular chemicals.
- Screw Feed Weigher – For fine powders: flour, cement, mineral powders.
- Gross Weighing – Product weighed directly in the bag; simple and economical.
- Net Weighing – Product pre-weighed in a weigh hopper for higher speeds.
- Single / Twin Head – Twin head doubles output for high-throughput lines.
Key Features and Specifications
- Accuracy up to ±20–50 g (product dependent) with coarse–fine dosing control.
- Throughput: 5–12 bags/min (single head) and higher on twin-head configurations.
- Dust-tight filling spout, integrated de-aeration, and optional pulse-jet dust extraction.
- Industrial PLC/HMI with recipe management, batch reports, and diagnostics.
- Conveyor with automatic bag kick-off to sewing or heat-sealing units.
- Rugged MS/SS contact construction for hygiene and long service life.
Applications of 25 Kg Bag Packing Machine
- Food & Agro – Rice, wheat, pulses, semolina, flour, sugar, salt with hygienic handling.
- Chemicals – Granular and powdered chemicals with dust-controlled, precise fills.
- Fertilizers – Urea, NPK, DAP with robust bags and reliable stitching/sealing.
- Minerals & Building Materials – Cement, fly ash, limestone, sand and allied products.
- Animal Feed – Cattle/poultry feed, premixes, and additives in consistent 25 kg packs.
Benefits of Using a 25 Kg Bag Packing Machine
- High Weighing Accuracy – Minimizes giveaway and ensures compliant bag weights.
- Higher Productivity – Automated conveying, clamping, and sealing shorten cycle time.
- Cleaner Workplace – Dust extraction and de-aeration improve shop-floor hygiene.
- Lower Operating Cost – Reduced manpower, faster changeovers, and fewer reworks.
