Automatic Tofu Box Filling & Sealing Machine is a fully automated food packaging system designed to fill tofu products into boxes (carton trays), apply a protective lid or film, and seal them hygienically for retail, distribution, or cold storage. These machines are widely used in tofu, soybean-based desserts (e.g., douhua), ready meals with tofu blocks, and refrigerated tofu cubes.

Below is a clear guide you can use to understand, specify, or source one.
🍱 What It Does
This machine performs the following in one continuous process:
Box/Tray Feeding
Automatically feeds empty tofu boxes (carton or plastic trays) into the line.
Filling / Dosing
Doses tofu blocks, cubes, slices, or processed tofu pieces into each box.
Can integrate with vibratory feeders, robotic pickers, or batch dosing systems.
Liquid / Sauce Filling (Optional)
Adds brine, marinade, seasoning liquid, or tofu broth as needed.
Film / Lid Placement
Places film (PET/PE laminate or easy-peel) or pre-cut lids over trays.
Heat Sealing
Heat-seals the film onto the box/tray for airtight closure.
Date / Lot Coding
Prints production date, batch, and expiry on film or box.
Finished Product Discharge

Pushes sealed boxes onto an outfeed conveyor for labeling or packing.
⚙️ Typical Working Process
Box Denester → Product Dosing → (Liquid Dosing) → Film/Lid Placement → Heat Sealing → Date Coding → Outfeed Conveyor

🧰 Key Machine Components
✔ Tray/Box Denester
