High-Viscosity Paste Automatic Filling Production Line for Chocolate Sauce and Semi-automatic Chocolate Sauce Filling Machine

Product Details
Chocolate sauce and cocoa sauce are typical high-viscosity sauces that easily solidify at low temperatures and carry suspended nut particles. Ordinary general-purpose filling machines are prone to common industry pain points such as valve clogging at low temperatures, uneven particle distribution, dripping, and stringing. This fully automatic filling production line, custom-made exclusively for chocolate sauce, has undergone dedicated constant-temperature tracing optimization across the entire chain from material storage to filling. It not only ensures a uniform and stable distribution of nut crumbs in every bottle but also prevents cocoa butter from solidifying and jamming materials at low temperatures, maintaining the smooth fluidity of the sauce throughout the process and drastically reducing material loss during mass production.

The constant-temperature storage tank of the equipment comes with a built-in low-speed anti-sedimentation stirring system, enabling stepless precise temperature control within the range of 30°C to 60°C. Even in low-temperature workshops below 15°C, it can slowly melt solidified cocoa sauce and maintain uniform fluidity, without the problem of localized overheating that undermines the cocoa flavor. The filling head adopts a custom large-channel anti-clogging valve body, whose discharge caliber is more than twice that of ordinary sauce filling machines, allowing nut crumb particles with a maximum diameter of 10mm to pass through. During the entire filling process, there is no material jamming or valve clogging, nor will there be half-filled or empty bottles caused by flow interruption. An integrated material-receiving tray is installed at the bottom of the filling station, where leaked residual sauce automatically flows back for recovery. This not only keeps the workshop floor clean and free of oil stains but also reduces the waste of high-value chocolate sauce.

All parts of the whole machine that come into contact with the sauce undergo mirror-polishing treatment with no dead corners. The quick-disassembly design allows for fast manual disassembly, assembly, and cleaning without tools. A CIP (Clean-in-Place) module is also available as an optional upgrade, enabling full-pipeline disinfection without machine disassembly and completely eliminating cross-flavor contamination between chocolate sauces of different flavors. The intelligent PLC system can store hundreds of sets of production parameters for different bottle types and different sauce formulas. When switching products, format changeover and debugging can be completed within 15 minutes, greatly improving the production efficiency of multi-SKU chocolate sauce. The entire line can flexibly adjust the sequence of stations according to the workshop layout of overseas customers, enabling rapid implementation without large-scale renovation of existing factories, thus building a fully closed-loop automated production chain from empty bottles to finished product palletizing.

What specifications can we customize for overseas buyers?
In response to the production demands of different chocolate food-producing regions around the world, we provide full-dimensional flexible customization services, with core customization directions covering 4 major categories:

‌Customization for exclusive material adaptation‌: For thick chocolate sauce containing a large amount of nut crumbs and low-temperature high-viscosity cocoa sauce, we customize oversized-diameter filling valves and add constant-temperature tracing layers to the entire pipeline, so as to maintain the uniform flow of the sauce throughout the process and eliminate the problems of low-temperature solidification leading to valve clogging and particle sedimentation & stratification.

‌Customization for production capacity and containers‌: According to the mainstream local chocolate sauce bottle types and flexible bag packaging dimensions of customers, we customize exclusive positioning fixtures and filling strokes. The number of filling heads can be expanded on demand from 2 heads to 12 heads, with the production capacity ranging from 1,200 bottles per hour to 3,500 barrels per hour, which can accurately match the needs from small chocolate workshops to large snack food groups.

‌Customization for regional regulatory compliance‌: For customers in different regions such as Europe, America, and Southeast Asia, we upgrade the material of food-contact parts that meet the corresponding regional standards, provide HALAL certification, FDA food contact compliance documents, and equip optional modules such as aseptic filling and full-machine anti-corrosion as required, to fully meet the local regulatory requirements for chocolate food.

‌Customization for localized implementation‌: The equipment is adapted to the industrial voltage standards of different countries, has built-in multi-language operation interfaces including English and Spanish, and supports direct docking with customers' existing third-party capping and palletizing equipment, enabling rapid access without modifying the original production line. A remote operation and maintenance module is also available, with the overseas technical team providing 24/7 online support for quick troubleshooting of equipment failures.

Machine Capacities for Different Production Volumes

‌Entry-level low-production-capacity tier‌: The basic constant-temperature model with 2-4 filling heads is suitable for small chocolate workshops and niche artisanal chocolate sauce brands with a daily output of less than 5,000 bottles. For the 100g specification, its hourly output ranges from 1,200 to 2,500 bottles. The whole line can be operated by only 2 workers, featuring a low procurement threshold and flexible production changeover, which fully meets the production needs in the start-up stage.
‌Mid-volume mainstay production-capacity tier‌: The main servo-driven model with 6-8 filling heads is suitable for medium-sized chocolate food factories with a daily output of 5,000 to 60,000 bottles. For the 100g specification, its hourly output ranges from 3,000 to 10,000 bottles. The filling error remains stable within ±0.8% during long-term operation, with evenly distributed nut particles, making it the mainstream choice for most large-scale chocolate sauce factories.

‌High-volume mass-production tier‌: The high-speed interconnected model with 10-12 filling heads is suitable for large export-oriented production enterprises with a daily output of more than 60,000 barrels. For the 5L large-capacity specification, its hourly output can reach 2,000 to 3,500 barrels. The heavy-duty transmission system supports 72 hours of continuous full-load operation, which matches the delivery pace of large-batch export orders.

FAQ

If the chocolate sauce solidifies in a low-temperature environment, can the equipment still perform normal filling?
The pipelines of the entire line and the storage tank are all designed with constant-temperature tracing, which can accurately control the temperature of the sauce, slowly melt the solidified chocolate sauce and maintain its uniform fluidity. There will be no problem of localized overheating that damages the cocoa flavor, achieving stable filling without valve clogging throughout the process.

For chocolate sauce with large nut crumbs, will valve clogging and material jamming occur during filling?
Our custom large-channel anti-clogging filling valve, paired with a spiral homogenizing stirring system, allows nut particles with a maximum diameter of 10mm to pass through. No valve clogging or flow interruption will occur throughout the filling process, and the distribution of nut crumbs in every bottle is uniform and stable.

How do we guarantee installation, commissioning, and after-sales services for overseas customers?
We provide full sets of multi-language operation manuals and high-definition installation & commissioning videos, along with 24/7 online remote video guidance. We can also arrange for engineers to complete the whole-process commissioning and operator training on-site.
