In the liquid addition stage of pet food, the filling machine achieves quantitative, stable, and traceable liquid injection through a high-precision intelligent control system. This system employs servo drive and closed-loop feedback technology, combined with visual recognition and weighing compensation algorithms, ensuring that the liquid addition error in each bag is controlled within ±1%. It is adaptable to raw materials of different viscosities and densities (such as meat juice, nutrient solution, and probiotic solution) and compatible with various packaging formats (bags, cans, and boxes). The system supports multiple formula management and allows for one-click switching of process parameters, achieving full automation from raw material input to filling completion.
Application areas cover the production of pet staple food, wet food, freeze-dried food, and functional health products, suitable for large-scale, continuous operation scenarios. A typical application case is a newly built intelligent production line project of a leading domestic pet food company: the original manual filling was inefficient and prone to errors, resulting in inconsistent product batches and increased costs. After introducing this filling system, the single line achieved a filling capacity of 3000 bags per hour, the overall equipment efficiency (OEE) increased to 89%, and the scrap rate decreased to below 0.3%. Simultaneously, the system integrates a MES data platform, enabling digital management of filling parameters, operation logs, and quality traceability, meeting food safety certification requirements.
The core value lies in solving the challenges of volatility and consistency during liquid addition through precise control and intelligent collaboration, ensuring product quality stability. Success factors include a self-developed dynamic pressure compensation algorithm, modular mechanical structure design, and scalable industrial IoT interfaces. This case demonstrates the company's core technological capabilities in intelligent equipment R&D, solution delivery, and data-driven production management, driving the intelligent and standardized upgrade of pet food manufacturing.
