Description

Tofu packaging device {bean curd packaging device}

The present invention relates to a tofu packaging device capable of unmanned and automatic mass packaging production of tofu through a series of automated processes.

In general, a tofu packaging device for packaging tofu through an automated process includes a conveying device for transporting one container at a time, an injection device for injecting whole tofu (hereinafter referred to as 'tofu') into the container, and a sealing device for sealing the top of the container. It is divided/composed of equipment, and tofu is packaged and produced through a series of processes.

Therefore, the conventional tofu packaging apparatus described above has a problem in that tofu packaging production is significantly reduced and tofu injection defects are frequent due to unstable positioning/transportation of the container.

In addition, as the film was placed on the top of the container and sealed with one splicer, the fusion failure of the film from the container was very frequent.

In addition, the input/discharge of the container was all done manually by the operator, which caused considerable hassle and inconvenience.

On the other hand, the conventional tofu packaging apparatus has a problem in that it is impossible to use containers of various shapes due to the use of a transfer frame specific to a square container.
