automatic quantitative bag filling machine

Feed production equipment serves as the core machinery for livestock breeding and the feed industry. Integrating raw material handling, grinding, batching, mixing, pelleting, extrusion, cooling, screening and packaging, these systems enable automatic and standardized production from raw grains to finished feed. Modern complete production lines feature high efficiency, energy conservation, environmental protection and precise formula proportioning, and are widely applicable to processing feed for poultry, livestock, aquaculture, ruminants and other varieties. 1. Raw Material Receiving & Cleaning Equipment Raw material receiving is the first procedure of the whole production line. Key equipment includes raw material silos, bucket elevators, screw conveyors and scraper conveyors, which undertake transportation and temporary storage of corn, soybean meal, wheat bran, premixes and other raw materials. Cleaning equipment mainly consists of primary cleaning sifters, magnetic separators and dust removal systems. These devices remove impurities such as stones, metal scraps and rope residues to protect downstream equipment and improve the purity of finished feed. 2. Grinding System Grinding determines feed fineness and animal digestion efficiency, and accounts for the largest proportion of energy consumption in the whole workshop. Hammer Mill: Highly versatile, suitable for conventional raw materials like corn and grains, featuring high grinding efficiency and easy maintenance. Roller Mill: Ideal for fine grinding with low breakage rate, mostly adopted for high-grade poultry feed and aquafeed. Water Drop Mill: Adopts optimized grinding chamber structure to cut energy consumption and achieve more uniform particle fineness. 3. Precision Batching & Mixing System Batching System: Equipped with electronic batching scales, automatic batching silos and PLC intelligent control system. It accurately measures major raw materials and additives according to feed formulas with controllable weighing errors. Mixing Equipment: Mainly twin-shaft paddle mixers and single-shaft ribbon mixers. They deliver superior mixing uniformity, evenly blend micro-additives rapidly and avoid material separation, ensuring consistent nutritional levels of feed. 4. Pelleting & Forming Equipment Pelleting is the core process of pellet feed manufacturing. It improves feed palatability, reduces feed waste and facilitates storage and transportation. Ring Die Pellet Mill: Large production capacity and compact pellets, perfect for large and medium-scale feed mills for mass production. Flat Die Pellet Mill: Simple structure and easy operation, widely used in small and medium farms and straw feed processing. Conditioner: Supports steam conditioning to soften materials, realize sterilization and gelatinization, and enhance pellet hardness and water resistance. 5. Extrusion & Special Forming Equipment Wet and dry extruders are specially designed for aquafeed, pet food and high-grade creep feed for piglets. Under high temperature and high pressure extrusion, feed achieves high gelatinization degree, excellent floating property and higher digestibility, while anti-nutritional factors can be eliminated effectively. 6. Post-processing Equipment Counter-flow Cooler: Rapidly lowers temperature and removes moisture to prevent pellet caking and mildew. Classifying Sieve: Removes unqualified broken particles and powder to guarantee uniform pellet size. Crusher: Breaks large pellets into crumbles for young poultry and young livestock. 7. Finished Product Packaging & Intelligent Control System Automatic packaging scales, bag sewing machines and palletizers realize automatic quantitative filling, sealing and stacking. Central control system monitors production output, temperature, moisture, formula ratio and other parameters throughout the whole process. It supports data traceability and fault alarm to realize intelligent manufacturing. 8. Equipment Advantages & Application Value High Efficiency & Energy Saving: Optimized mechanical structure and variable frequency control reduce power consumption and dust pollution. Stable Product Quality: Precise proportioning and uniform pellets guarantee consistent nutrition performance. Wide Compatibility: Capable of producing powder feed, pellet feed, extruded feed, crumbles and other multiple feed types. Intelligent & Labor-saving: High automation level cuts labor costs and improves production safety. Modern feed production machinery has evolved from standalone machines to integrated full-process solutions. Balancing production capacity, product quality and environmental compliance, it acts as vital support for modern breeding industries to lower production costs, boost profits and ensure feed safety.
