Product Details
This fully automatic plastic cup filling machine for dipping sauces and condiments is an integrated equipment exclusively developed for the mass production scenarios of takeout dipping sauces and commercial small-serving dipping sauces. The entire process, from empty cup feeding, quantitative filling to sealing and trimming, is fully automated. It perfectly adapts to the mass production demands of small-specification dipping sauces for catering chains and hot pot ingredient supply chains, completely replacing manual dispensing, and drastically improving the packaging consistency and production efficiency of dipping sauce products.

The whole machine is designed in strict compliance with food GMP production standards. All parts in contact with the sauce are made of 316L food-grade stainless steel, and all pipe connections adopt quick-install joints. The smooth inner walls leave no sanitary dead corners, which can effectively prevent residual high-viscosity sauces such as sesame paste and peanut butter from deteriorating. It meets food contact safety requirements and supports connection to a CIP (Clean-in-Place) system, enabling in-depth deep cleaning of the whole machine without manual disassembly, fully satisfying the production demands of the catering industry for frequent product changes and rapid cleaning.

The equipment is equipped with an intelligent closed-loop filling system optimized for particle-containing dipping sauces, which specifically solves the industry pain point of particles such as crushed peanuts and crushed chili in hot pot dipping sauces easily jamming the equipment. It adopts a sauce-dedicated rotor pump body, and non-contact magnetic drive avoids mechanical seal contamination. The two-stage filling mode first performs high-flow rapid filling, and automatically switches to slow drip filling when approaching the target volume. Combined with the anti-drip vacuum suck-back device, the residual material is sucked back instantly after filling is completed, completely eliminating the problem of sauce stringing and dripping that contaminates the cup rim, and avoiding residual sauce overflow after the dipping sauce cup is sealed.

The heat-sealing station adopts a two-time sealing design, paired with a PID precise temperature control module that keeps the temperature fluctuation within ±1°C, ensuring that the aluminum foil/composite film is completely sealed with the cup rim. No sauce leakage will occur even if the dipping sauce cup is inverted, and the sealing qualification rate can reach over 99.5%. The equipment comes with built-in no-cup detection and abnormal filling alarm functions: filling automatically stops when there is no cup, avoiding material waste from empty filling. The fault self-diagnosis system can monitor 12 key operating indicators in real time, and indicate abnormal points through color coding, enabling ordinary operators to quickly handle common problems.

The equipment adopts a modular layout design. The full set of molds can be replaced within 10 minutes via the pneumatic locking device, realizing rapid switching between different specifications of dipping sauce cup types and filling volumes. Multiple pre-stored dipping sauce production formulas can be called with one click without repeated parameter debugging, increasing product change efficiency by 60% compared with traditional models. The core transmission components of the whole machine adopt internationally renowned brands, with a mean time between failures (MTBF) exceeding 8000 hours. The drawer-type maintenance structure reduces daily cleaning time by 70%. A single unit can operate independently, or be connected with automatic cup sorting, spoon inserting, labeling and box packing equipment to form a complete production line, fully meeting the different capacity requirements from small catering processing factories to large chain supply chains.

FAQ
Can this equipment fill granular hot pot dipping sauces containing crushed peanuts and crushed chili peppers?
Yes. The equipment can be customized with special flow channels and filling nozzles designed for large particles, which will not cause particle clogging. During the filling process, the integrity of particles will not be damaged, and it can stably adapt to various types of dipping sauce products with particles.

Is the model changeover and debugging for small dipping sauce cups of different specifications troublesome?
Extremely convenient. The equipment is equipped with a quick changeover system as standard. The mold replacement can be completed within 10 minutes through the pneumatic locking device, and the pre-set production formula can be called with one click. There is no need to repeatedly adjust the mechanical structure manually, making it highly suitable for the production scenarios of multi-SKU dipping sauces.

High-viscosity sesame paste is prone to residue and solidification. Is the equipment easy to clean?
All parts in contact with materials adopt a quick-assembly structure, which can be quickly disassembled for flushing. It also supports the optional CIP (Clean-in-Place) on-line cleaning system, which can complete the circulating cleaning of the whole machine without disassembling the equipment, preventing the sauce from remaining, solidifying and clogging the pipelines.

The sealing of takeaway dipping sauce cups is prone to sauce leakage. Can this equipment solve this problem?
The equipment adopts a double heat-sealing process, combined with PID precise temperature control, and has optimized the pressure for small-specification thin cups. The edge of the cup mouth is evenly heated, the sealing performance is greatly improved, and no sauce leakage will occur even in the inversion test.

I already have an existing cup-making production line. Can I purchase this filling machine separately for docking?
Absolutely yes. The equipment supports flexible docking with existing cup-making machines, conveyor lines and other equipment, and can also make customized adjustments according to your existing workshop layout and equipment specifications. The upgrade can be completed without replacing the entire production line.

What about the after-sales guarantee of the equipment?
The whole machine comes with 1-year free warranty, and extended warranty services are available for core components. It supports remote diagnosis to solve more than 80% of technical problems online. For complex faults, engineers can provide on-site treatment quickly, maximizing the guarantee for the continuous production demands of the catering supply chain.
