It is said.
[0005]
[Means for Solving the Problems]
The present invention is to solve the previous SL problem, the bottom of the forming box and placed tofu tofu in molding boxes to the molding box lid for forming press by applying between are composed of a punching metal of said bottom mold In the manufacturing method of cotton tofu by pressing to produce cotton tofu, in the middle of the step of pressing the tofu placed in the molding box, the top and bottom of the molding box are reversed and the tofu in the molding box is pressed again. Provided is a method for producing cotton tofu using a punched metal molding box.
[0006]
When tofu is molded and pressed in a punching metal molding box, the tofu bites into the punching surface easily on the lower surface of the molding box. This has a great influence on the balance between the biting force of tofu into the punching hole and the elasticity of tofu, and the presence or absence of whey drained from the tofu. That is, since whey accumulates on the top surface of the tofu in the molding box, it is difficult for tofu to adhere to the punching surface, and conversely, the tofu bites easily on the bottom surface of the molding box with less whey.
[0007]
In the present invention, as described above, since the tofu in the molding box is pressed by turning the molding box upside down during the pressing process of pressing for a predetermined time, the balance of the molding press on the upper surface and the lower surface of the molding box becomes equal. The tofu thus obtained is easily released from the molding box.
[0008]
When tofu produced by adding a coagulant to soy milk is placed in a punching metal mold box and pressed to produce cotton tofu, the ability of the tofu to punch into the punching holes It is extremely important to balance the elasticity (repulsive force).
[0009]
When molding pressure is continuously applied to the tofu placed in a punching metal mold box, the force of the tofu biting into the punching holes exceeds the elasticity of the tofu, and the tofu adheres to the punching surface. On the other hand, when the load at the time of the molding press is insufficient, the elasticity of the tofu exceeds the force of the tofu biting into the punching hole, resulting in a state of insufficient molding and causing rough skin in the tofu.
[0010]
In the production method of the wood cotton tofu, after Jo Tokoro time forming press and to open the pressure tofu disconnect the pressing pressure to stop the press bites into punching surface tofu releasability is improved.
[0011]
And method for producing tofu in which the pre-marked press pressure to pull in the middle, and a middle method for producing tofu in which inverts the upper and lower molding boxes pressing step, when both carry out the rough skin caused tofu surface It has a favorable effect in preventing and preventing tofu from peeling off at the time of mold release.
[0012]
That is, in order to solve the above-mentioned problems , the present invention provides a molding box in which the bottom of the molding box and the lid for molding and pressing the tofu in the molding box against the bottom are formed of punching metal . There is also provided a method for producing cotton tofu, which comprises a step of inverting the upper and lower sides of the molding box in the middle of the production process of cotton tofu after pressing the put tofu for a predetermined time and repeating the process of stopping the pressing. According to this method, the balance of the molding press on the upper and lower surfaces in the molding box is well balanced, and tofu with high commercial value can be obtained.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the manufacturing method of the cotton tofu by this invention is demonstrated concretely based on one Embodiment. In this embodiment, the tofu is put into a molding box whose upper and lower surfaces are made of stainless steel punching metal, the lid forming the upper surface is crushed and pressed for a predetermined time, for example, about 10 seconds, and then the press is stopped and the lid is closed. Is lifted and the press pressure is released for 3 to 5 seconds to release the pressure that the tofu bites into the punching surface. The cycle time for releasing the press pressure after pressing in this way is 15 to 20 seconds. After repeating this press pressure load and press pressure release cycle, the molding press is continued for about 30 minutes to obtain cotton tofu.
[0014]
