Full-Auto Sticky Wet Pet Food Weighing and Filling System | High-Viscosity Dog & Cat Food Packaging Line
This professional, fully automated weighing and filling system is exclusively customized for high-viscosity wet pet food products, including meat puree, meat jelly wet food, gravy-coated soft dog food, mousse cat food, minced meat treats, and other sticky pet nutrition products. It integrates anti-sticking precision weighing, broth/gravy filling, and double-station high-speed packaging into one turnkey solution, with full SUS304 stainless steel construction, IP65 full-machine waterproof rating, and washable design. This system perfectly solves the core industry pain points of sticky wet pet food production, fully complies with global pet food safety standards, and helps manufacturers achieve efficient, hygienic, and compliant continuous production.
Industry Pain Points
·Severe material sticking, bridging and blockage: High-viscosity meat puree, meat jelly and gravy-coated products easily stick to the hopper wall, cause bridging and blockage in ordinary weighing equipment, leading to unstable weighing accuracy, massive raw material residue and waste, and frequent unplanned downtime for manual scraping and cleaning.
·Difficult hygiene cleaning and high food safety risks: Wet pet food residues are prone to breed bacteria and deteriorate rapidly. Ordinary equipment has sanitary dead corners, cannot be washed with water as a whole, and fails to meet strict FDA, BRC, AAFCO and other international pet food safety standards, which restricts export to mainstream global markets.
·Poor accuracy of solid-liquid mixed packaging: Sticky solid ingredients and broth/gravy require synchronous quantitative filling, but ordinary equipment cannot achieve coordinated control, resulting in inconsistent solid-liquid ratio in each package, unstable product quality, and non-compliance with pet food nutritional formula regulations.
·Insufficient waterproof performance and short equipment life: Wet pet food production requires a humid environment and frequent flushing. Ordinary equipment has low waterproof grade, its circuits and sensors are easily damaged by water, leading to high failure rate, huge maintenance costs and extremely short service life.
·Heavy manual dependency and low production efficiency: Sticky materials require frequent manual scraping, cleaning, feeding and bagging, leading to soaring labor costs, high cross-contamination risks, and low production efficiency, which cannot support large-scale continuous production.
·Poor sealing performance and short shelf life: Wet pet food has extremely high requirements for sealing. Ordinary packaging machines have uneven sealing, leading to liquid leakage, bag expansion, product spoilage, short shelf life, and huge after-sales return and complaint losses.

Standard Automated Workflow
·High-viscosity wet pet food raw materials are fed into the inclined elevator, which smoothly conveys the materials to the upper feeding hopper of the 24-head screw weigher, with anti-sticking design to avoid material residue.
·The 24-head 1.0L screw weigher adopts forced screw feeding, operates in 12x2 dual working mode under PLC control, and the scraper hopper completes high-precision quantitative weighing without wall sticking. Unqualified products are automatically eliminated by the rejecting device, and qualified materials are discharged synchronously through the double timing hopper.
·At the same time, the double-station bag packaging machine automatically completes premade bag picking, opening and positioning, and accurately docks the feeding port and liquid filling pump.
·The weighed high-viscosity materials are accurately discharged into the opened bag, and then the liquid filling pump completes synchronous quantitative filling of broth/gravy according to the preset formula, ensuring accurate solid-liquid ratio.
