Full-automatic Bottled Special Filling Whole Line for Two-tone Chocolate sauce filling machine and Cocoa Paste

Product Details
Ordinary single-channel filling machines are fundamentally incapable of delivering uniform layering and swirling effects for two-tone chocolate spreads. They are highly prone to the industry-wide pain points of color mixing between the two sauce streams, uneven stratification, and misaligned distribution of nut fragments, which directly ruin the appearance and market appeal of the final product. This fully automatic filling production line, custom-built specifically for bottled two-tone chocolate spreads, has undergone exclusive optimization across the entire chain from dual-channel material storage to synchronous filling. It not only precisely controls the discharge ratio of the two sauces to achieve a variety of viral visual effects such as distinct layering and spiral swirling, but also prevents cocoa spreads from solidifying and jamming at low temperatures, maintaining the silky fluidity of both sauces throughout the process – perfectly meeting the mass production demands for popular two-tone chocolate spreads.

Equipped with two completely independent constant-temperature storage tanks, each precisely regulating temperature within the 30°C-60°C range. Even when the two sauces have vastly different melting points and viscosities, the system can maintain uniform fluidity for each stream separately, eliminating the risk of valve blockage caused by low-temperature solidification in any single sauce line. This fundamentally eradicates quality defects such as missing color in individual bottles or half-bottle color mixing. The dual-channel synchronous anti-clogging filling valve adopts an independent large-channel valve body, with the two discharge nozzles precisely coaxially aligned, allowing nut fragments up to 8mm in diameter to pass through. During filling, the two sauces are discharged synchronously at a pre-set ratio, creating not only distinct upper and lower layered effects, but also continuous and uniform spiral patterns by rotating the bottle – ensuring a highly consistent two-tone visual effect across every single bottle. Two independent residual sauce recovery trays are installed at the bottom of the filling station to separately collect dripping residual materials from the two sauces, preventing cross-flavor contamination and minimizing waste of high-value chocolate spreads to the greatest extent.

All parts of the entire machine that come into contact with the sauce undergo seamless mirror polishing treatment. The quick-disassembly design allows for fast manual disassembly and cleaning without tools. An optional dual-channel independent CIP (Clean-in-Place) module is also available, enabling separate disinfection of the two pipelines without dismantling the machine, thoroughly eliminating cross-flavor mixing between two-tone spreads of different flavors. The intelligent PLC system can store hundreds of sets of production parameters for different bottle types, two-tone ratios and pattern effects. When switching products, format changeover and commissioning can be completed within 20 minutes, eliminating the need for repeated adjustments to the discharge speed of the two sauces, and drastically improving production efficiency for multi-SKU two-tone chocolate spreads. The entire line can flexibly adjust the sequence of stations according to the workshop layout of overseas clients, enabling rapid deployment without large-scale modification of existing factory buildings, thus building a fully closed-loop automated production chain from empty bottles to finished product palletization.

What Specifications Can We Customize for Overseas Buyers?
In response to the differentiated production needs of different global regions specializing in casual chocolate food production, we provide full-dimensional flexible customization services, with core customization directions covering four major categories:

‌Customized Material-Specific Adaptation‌: For high-viscosity two-component two-tone spreads and two-tone spreads with large nut fragments, we customize independent filling valve bodies with corresponding flow diameters, and add constant-temperature heat tracing layers to each of the dual pipelines. Even when the viscosity difference between the two sauces exceeds 3 times, synchronous discharge without color mixing or material blockage is guaranteed.

‌Customized Production Capacity & Visual Effects‌: According to clients' product design requirements, multiple filling modes such as layering, swirling, and dual-tone striping can be customized. The number of filling heads can be expanded from 2 to 8 as needed, with production capacity ranging from 800 bottles/hour to 2800 bottles/hour, precisely matching the mass production demands of everything from small viral chocolate workshops to large casual food groups.

‌Customized Regional Compliance‌: For clients in different regions such as Europe, America and Southeast Asia, we upgrade the material of food-contact parts to meet regional standards, provide supporting HALAL certification and FDA food contact compliance documents, and optionally integrate modules such as aseptic filling and full-machine corrosion resistance to fully satisfy local regulatory requirements for chocolate food products.

‌Customized Localized Deployment‌: The equipment is adapted to industrial voltage standards of different countries, features a built-in multi-language operation interface including English and Spanish, supports direct docking with clients' existing third-party capping and labeling equipment for rapid integration without modifying the original production line. An optional remote operation and maintenance module is also available, with overseas technical teams providing 24/7 online rapid troubleshooting for equipment faults.

Machine Capacities for Different Production Output Levels

For 200g specification, it delivers an output of 800-1500 bottles per hour, with only 2 workers required to operate the entire line. It features a low procurement threshold and flexible production changeover, fully meeting the small-batch custom production needs at the start-up stage.
‌

Mid-Range Mainstream Capacity Tier‌: The 4-head mainstream servo-driven model, suitable for medium-sized chocolate food factories with a daily output of 3,000 to 40,000 bottles. For 200g specification, it achieves an output of 1800-2200 bottles per hour, with a long-term operation filling error stably maintained within ±1%. The two-tone layering and swirling effect is highly uniform across every bottle, making it the mainstream choice for most large-scale two-tone chocolate spread factories.

‌High-Capacity Mass Production Tier‌: The 6-8 head high-speed linked model, suitable for large export-oriented manufacturing enterprises with a daily output of over 40,000 buckets. For the 1kg large-capacity specification, the hourly output can reach 2200-2800 bottles. The heavy-duty transmission system supports 72 hours of continuous full-load operation, adapting to the delivery rhythm of large-batch export orders for popular two-tone chocolate spreads.

FAQ
Q: The two chocolate spreads have different viscosities – will there be color mixing or misaligned layering during filling?
A: Two independent servo metering systems precisely control the discharge speed of each sauce stream separately, and the dual-channel coaxial filling valve discharges synchronously. Even with significant viscosity differences, the two-tone ratio can be precisely controlled, resulting in clear layering without color mixing, smooth and uniform swirling patterns, and consistent effects across all bottles.

Q: If the two cocoa spreads solidify in a low-temperature environment, can the equipment still operate normally?
A: Two independent constant-temperature heat tracing systems regulate temperature separately. The temperature can be adjusted individually based on the melting point of each sauce, allowing the solidified spreads to melt slowly while maintaining uniform fluidity. This avoids local overheating that would compromise the cocoa flavor, ensuring stable filling without valve jamming throughout the process.

Q: How do you guarantee installation, commissioning and after-sales support for overseas clients?
A: We provide full multi-language operation manuals and high-definition installation and commissioning videos, with 24/7 online remote video guidance. We can also arrange for engineers to be on-site to complete full-process commissioning and operator training. Core components come with an extended 18-month warranty, and overseas regional spare part warehouses enable fast delivery of wear parts.

Q: Is format changeover troublesome when switching between different two-tone flavors and pattern effects?
A: The entire equipment adopts a quick-disassembly fixture design. When switching between different bottle types and sauce formulas, there is no need to replace the core components of the valve body. Format changeover and commissioning can be completed in 20-30 minutes, and production can be started directly by recalling the pre-set production parameters stored in the touch screen.

Q: With long-term mass production, what is the maximum material loss that can be controlled?
A: Equipped with a dual-channel independent residual sauce recovery system, the equipment ensures zero dripping throughout the filling process. The monthly material loss during long-term mass production can be controlled within 0.6%, which is far lower than the industry average loss level of 3%, drastically reducing waste of high-value two-tone chocolate spreads.

Q: Can attractive two-tone effects be achieved on irregular viral bottles and wide-mouth jars with large calibers?
A: Yes, the equipment can be customized with exclusive positioning rotation fixtures according to clients' special bottle types, precisely controlling the bottle rotation speed and filling path. Whether it is layering, swirling or dual-tone striping effects, all can be perfectly presented in various irregular bottle shapes.
