The Automatic Natto Cup Filling and Sealing Packaging Machine is engineered specifically for packaging natto (fermented soybeans) and similar viscous or particulate foods in pre-made cups or boxes. It integrates automatic cup/box feeding, quantitative filling, film sealing and product discharge into one continuous line to support hygienic, high-throughput production. Natto is typically filled before fermentation; the machine is designed to handle containers through this process and subsequent cooling, refrigerated maturing and secondary packaging stages, ensuring consistent fill weight, secure seals and reliable shelf life.
• Fully Automatic Operation – The machine integrates cup feeding, filling, sealing, and output in one automated process.
• High Filling Accuracy – Equipped with a volumetric or piston filling system to ensure precise filling volume.
• Food-Grade Materials – All product contact parts are made of SUS304 stainless steel to meet food hygiene standards.
• Stable and Durable Structure – Designed with high-quality components to ensure long-term reliable operation.
• Easy Operation and Maintenance – Simple control system and convenient machine structure for easy cleaning and maintenance.
These anti-clog natto cup sealing machine capabilities set it apart from standard cup fillers when dealing with highly viscous fermented products.

Our automatic natto cup filling and sealing machine and hygienic natto packaging machine are trusted in:
• Ice cream cups
• Natto (fermented soybean)
• Yogurt and dairy products
• Fruit puree and jam
• Sauces and condiments
• Dessert cups and pudding
The custom natto cup filling and sealing machine supports various cup sizes and can be integrated with upstream fermentation and downstream labeling systems.
Filling before fermentation In standard natto production, inoculated soybeans are filled into containers first, then fermented. The machine is designed to handle filled containers through the subsequent fermentation, cooling and maturing stages, with seals that withstand the process while remaining easy for consumers to open.
Compatibility with refrigerated maturing & secondary packaging After fermentation, natto undergoes refrigerated maturing (typically around 5°C). The line can be integrated with cooling sections and downstream secondary packaging (cartoning/overwrapping) while maintaining strict temperature control to avoid temperature rise and unwanted secondary fermentation.
Support for multiple container formats Natto is packed in round cups, square cups and boxes. The machine supports different molds and sealing formats to match your market requirements—whether you need high-barrier film, breathable structures or easy-peel lids for retail or foodservice packs.
With deep expertise in viscous and particle-containing food packaging machinery, Yinuo Pack stands out as a reliable natto cup filling machine manufacturer by offering:
Proven for natto & fermented soybeans
Designed specifically for natto and other fermented soybean products, the machine handles viscous, sticky and particulate textures with consistent dosing and stable sealing performance, reducing giveaway and product waste.
High capacity & scalable speed
Production capacity from 1800 to 20,000 cups/hour supports both medium plants and large-scale industrial natto lines, enabling you to start with a baseline capacity and upgrade as demand grows.
