Leading 25 Kg Open Mouth Packing Machine Manufacturer
Introduction to Automatic 25 Kg Open Mouth Bagging Machines
The 25 Kg Open Mouth Packing Machine is an essential piece of equipment designed for the high-speed and accurate filling of open-mouth bags in the 5 kg to 25 kg weight range. Used extensively across the food, chemical, agricultural, and mineral industries, this machine handles a wide variety of free-flowing and semi-free-flowing materials such as powders, granules, and pellets. Reputed manufacturers like Samirika Industries Pvt. Ltd. provide robust, fully automatic systems that ensure high packaging precision, increased productivity, and seamless integration with conveying and bag closing equipment.
Working Principle and Operational Flow
The operational flow of a 25 Kg Open Mouth Packing Machine is focused on precise quantitative weighing followed by controlled product discharge. The process begins with the automatic or manual placement of a pre-made open-mouth bag onto the filling spout. A highly accurate weighing system (either net or gross weight scale, often controlled by a PLC) measures the exact 25 kg of material. Once the target weight is reached, the material is rapidly and cleanly discharged into the bag. The filled bag is then released onto a conveyor belt, which transports it to an automatic bag closing station for sewing or heat sealing, completing the streamlined and highly efficient packaging cycle.
Types of 25 Kg Open Mouth Packing Machines
- Gravity Feed Baggers – Best suited for free-flowing granular products like seeds, rice, sugar, and salt.
- Screw Feed Baggers – Ideal for fine and non-free-flowing powders such as flour, starch, cement, and chemical additives.
- Belt Feed Baggers – Used primarily for semi-free-flowing or coarse materials like animal feed pellets and certain fertilizers.
- Net Weighing Systems – Material is weighed in a separate hopper before being dropped into the bag, ensuring maximum speed.
- Gross Weighing Systems – Material is weighed directly inside the bag, optimizing the filling process for cost-efficiency.
Key Features of 25 Kg Open Mouth Bagging Equipment
- High-precision load cell and PLC control for accurate 25 kg filling, minimizing product giveaway.
- Versatile design to handle various bag materials like woven PP, paper, and plastic with quick changeover.
- Built-in dust control system and de-aeration feature for clean operation, especially with fine powders.
- Stainless steel construction (SUS304) for contact parts, ensuring hygiene and durability in food and chemical industries.
- Seamless compatibility with downstream equipment such as bag closing (sewing/sealing) and palletizers.
Applications of 25 Kg Open Mouth Packing Machine
- Food Industry – Used for packaging 25 kg bags of rice, flour, pulses, sugar, salt, coffee beans, and pet food with strict hygiene and weight consistency.
- Chemical Sector – Essential for bagging powdered and granular chemical additives, detergents, PVC resin, and other specialty chemicals.
- Agricultural Products – Perfect for packaging seeds, animal feed, fertilizers (urea, NPK), and bulk grains in medium-sized 25 kg sacks.
- Construction & Mineral Industry – Applied for filling building materials like cement mixes, plaster, limestone powder, and various fine mineral products.
Benefits of Integrating a 25 Kg Open Mouth Packer
- Exceptional Accuracy – Ensures precise material dosing in every 25 kg bag, leading to compliance with packaging standards and reducing material waste.
- High Production Throughput – Capable of packaging hundreds of bags per hour, drastically increasing line efficiency and meeting large-scale demand.
- Automation and Safety – Minimizes manual labor and handling, enhancing workplace safety and reducing the chance of human error or fatigue.
- Flexibility and Versatility – Easily adapts to different product types (powders/granules) and various bag dimensions within the 5-25 kg range.
