Description

  The present invention relates to a method for producing mash tofu (including colander tofu) from raw material tofu (mainly silky tofu), a mash tofu production apparatus used in this mash tofu production method, and this mash tofu It relates to the tofu produced by the production method.

  Conventionally, in the production of tofu, for example, the raw tofu contained in the raw material container is repeatedly scooped up by an operator using Otama, which is a cooking tool, and the scooped tofu lump is removed from the bottom of the product container. It is done manually by laminating the layers sequentially, and finally inverting the large tofu lump that has been scooped up to the end of the tadama.

  As described above, most of the conventional mash tofu production has been carried out manually, and thus has the following problems.

First, time production is limited by the number of workers. At the same time, production increases lead to an increase in the number of workers. As a result, it will lead to a significant increase in labor costs.
Since the worker manually fills the tofu, an unspecified number of workers come into contact with the product to be produced, which is a problem in terms of hygiene compared to a cleaned machine.
Since it is performed manually, in order to ensure the quantitativeness of each product, it is necessary to perform it by a skilled worker, and it is also necessary to perform measurement confirmation, and productivity is low.
The tofu that cannot be picked up always remains in the raw material container, and the raw tofu is lost.

Conventionally, a tofu filling device in which tofu is filled by a machine is known (see Patent Document 1).
However, this conventional tofu filling apparatus is a method of filling a product container as it is without breaking down the raw material when filling the raw material into the first container for tofu.

In other words, since the raw materials (cracking and cutting), which are the characteristics of the tofu, are not performed at all, the product does not take into account the element of rebinding multiple tofu chunks after breaking. End up.
In this case, there is a problem that the handmade feeling of the hand-made tofu produced by hand cannot be obtained and the product value becomes low.
