Classic Side-by-Side Comparison: How Darin Transforms Your Production Line

This is the most intuitive comparison method. By presenting side-by-side views of pet food production sites before and after Darin’s upgrade, you can clearly observe the significant changes in equipment, layout, and operation methods. This comparison highlights the transformation from “traditional mixing” to “intelligent formulation,” and from “manual operation” to “high-speed automation,” especially evident in the production of diverse products like bird treats bars, dog chews, and rawhide rolls. Choose Darin, choose efficiency and excellence!

space design before

Before Renovation (Traditional Equipment)

"Old pet food production line, with outdated equipment, low space utilization, and cluttered material stacking. Manual weighing and batching lacked precision, traditional extrusion and drying effects were unstable, and manual sorting and packaging were time-consuming and unhygienic, leading to low production efficiency, poor product consistency, and food safety risks. For example, bird treat bar forming and rawhide roll shaping relied heavily on manual labor, limiting capacity."

  • Labor-intensive: Typically required 6-8 operators.
  • Space Waste: Unreasonable layout, narrow passages.
  • Capacity Bottleneck: E.g., bird treats bar only 100kg/hr, dog chews and rawhide rolls also limited.
  • Unstable Quality: Poor product appearance, inconsistent drying effect, uneven filling.
space saving straight line design

After Renovation (Darin Smart Equipment)

"Darin's modern intelligent pet food production line features optimized layout, high space utilization, and a clean & orderly environment. Darin's smart batching system ensures precise formulation, high-efficiency twin-screw extruders (e.g., bicolor dog food lines) & intelligent drying ovens (e.g., dog chew drying systems) improve efficiency & product quality. Products undergo Darin's visual inspection, automatic filling (e.g., puffed snack core filling 6 lines into one), and high-speed automated packaging. The entire line is precisely controlled by Siemens PLC, with real-time visual monitoring, significantly boosting capacity and food safety standards."

  • Highly Automated: Labor demand reduced to 1-2 people, e.g., rawhide roll line from 6-7 to 2-3 people.
  • Space Saving: Straight-line design, optimized factory layout.
  • Capacity Leap: Bird treats bars up to 300-400kg/hr, puffed snacks up to 600kg/hr, dog chews up to 200-300kg/hr.
  • Superior Quality: Smoother product surface, better drying effect, more perfect filling, mold upgrades allow simultaneous production of more treats.
