Lactone Silken Tofu (Soft Tofu): soy milk can be filled into boxes and then sealed after

coagulating and seasoning. Chunlai recommends the automatic filling and sealing

machine for boxedjapanese soft tofu. The operator just needs to set the filling amount

for box capacity and the machine will automatically drop the boxes,fill, seal, and

discharge the sealed boxes.

Regular Tofu(Firm Tofu): after Tofu is formed by Tofu pressing machine, being cut into

small cubes through manual cutting process, the small Tofu cubes can be put into plastic

box and can be sealed by this sealing machine. Besides, it is optional to have date

printer to print the production date or shelf life on the sealing film.

Soybean Roll: Product-filled trays are placed manually,or automatically feeding

product-filled trays into the carriers by conveyor, or automatically de-nested empty trays

into the carriers, then fill soybean rolls manually inside the trays. Trays are transferred

to sealing position, the sealing head comes down, the film and trays are then

compressed against the heated upper tooling to activate the sealing properties against

the tray, while simultaneously cutting the film. Finally, after seal transfer to the next

cycle ejects to the out-feed of the machine.

Film is cut in between each container, leaving absolutely no waste offilm.And

potentially saving in material costs. Further savings include reduced labor costs ano

downtime by eliminating the need to handle and discard excess film.

The temperature and sealing time are regulated to allow for the sealing of different

types of film and trays.
