[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, details of the present invention will be described with reference to illustrated embodiments. This embodiment is a method for molding silk tofu. First, a tofu mold box S shown in FIGS. 4 and 5 will be described. Reference numeral 1 denotes a bottom plate made of an electrically insulating polypropylene resin, which is close to both ends in the width direction. From the top to the engagement groove 21 of the width side plate 2 facing the titanium electrode side plate 3 having the flange 31 with the upper end bent outwardly by engaging the width side plate 2 of the same material with the notched dovetail groove 11 respectively. It is inserted into the mold box S. The size of the mold box S is usually an elongated shape with a width of about 20 cm for 1-2 tofu and a length of 100 cm.
[0006]
A reinforcing metal fitting 23 is attached to the width side plate 2, and a reinforcing material 13 also serving as a footrest is attached to the lower surface of the bottom plate 1 to prevent distortion of the bottom plate. In addition, an energization terminal is brought into pressure contact with the upper end flange 31 of the electrode side plate 3 and energized, and the mold box is heated by the generation of Joule heat.
[0007]
Using this mold box S, as shown in FIG. 1, it is circulated in the width direction of the mold box with the electrode side plate 3 side approaching each other as a two-stage upper and lower mold box arrangement. That is, in the upper stage, the transfer means for intermittently extruding and transferring the mold box S by the cylinder 5 from one end to the other end, and in the lower stage, the transfer for intermittently extruding and transferring the mold box by the cylinder 6 from the other end to the one end. Means are provided, and the upper and lower stages are in the reverse transfer direction.
[0008]
Also, a lowering transfer means for lowering and placing the mold box sent to the other end of the upper stage by the cylinder 7 at the other end of the lower stage, and a cylinder 8 sent to the one end of the lower stage by the cylinder 8 The mold box is intermittently circulated with ascending transfer means for ascending arrangement.
[0009]
Next, the tofu molding process according to this example will be described. First, as shown in FIG. 1, the empty box S raised at one end of the upper end is filled with soy milk and a coagulant, and after filling, one pitch is placed on the other end side. At the sent position, the current-carrying terminal 4 is lowered by a cylinder and pressed against the upper end flange 31 of the electrode-side plate 3 to be energized, and the mold box S is heated by Joule heat to assist solidification.
[0010]
This heating is performed every time the mold box is transferred to a position just before the other end portion of the upper stage, and in this example, the heating is performed for 4 pitches. The energizing terminal 4 is lifted by the cylinder every time it is transferred and is separated from the electrode side plate 3, and is lowered and pressed against the electrode side plate 3 at each stop, and the energizing terminal 4 is integrated with this 4 pitch. It goes up and down.
[0011]
Next, the heating type box transferred to the other end of the upper stage is lowered by the cylinder 7 to the other end of the lower stage, then sequentially sent to one end side, and tofu is transferred to the center of the lower stage. It is aged.
[0012]
Then, after maturation, the mold box transferred to the lower central part is sent to the cooling water tank N disposed horizontally by the cylinder 9, and the tofu block K is cut in a state where the electrode side plate 3 is detached in the water tank N. It is pushed out to the process side and taken out. In the empty box from which the tofu has been taken out, the electrode side plate 3 is restored and transferred to the lower middle part.
[0013]
Next, the empty box moves by one pitch, and the electrode box 3 is lifted by the cylinder at that position, and the empty box is washed with the nozzle fountain. After the cleaning, the electrode side plate 3 is restored and transferred to one end, and transferred to the upper end by the cylinder 8.
[0014]
In this way, as shown in FIGS. 2 and 3, the filling step A for filling soy milk and a coagulant into the empty mold box raised at one end of the upper end, and the respective mold boxes while being sent to the other end of the upper stage A tofu heating step B for energizing and heating the electrode side plate 3, a tofu ripening step C while being transferred from the other end of the upper stage to the lower middle part, and one end side of the final position of the aging step A discharging step D1 for transferring the mold box to the cooling water tank N, a tofu removing process D2 for removing the electrode side plate 3 and taking out the tofu block in the cooling water tank, and returning the empty box in the water tank to the lower base position. The tofu is sequentially formed and taken out by the backward feeding process D3 and the cleaning process E in which the empty box is cleaned with the nozzle fountain.
[0015]
According to this example, since the mold box is a two-stage vertical circulation transfer, the equipment can be installed in a narrow place. In addition, by using an elongated mold box, electric heating can be performed uniformly and quickly, and a homogeneous tofu can be obtained.
[0016]
Although the present embodiment is the above method, the present invention is not limited to this. For example, in the formation of cotton tofu, the removal process in the previous example is performed not at the water tank but at the site where the tofu block is transferred to another dehydration mold box. After the tofu block is transferred, pressurization is performed. It is transferred to the cooling water tank through the dehydration process, and only the takeout part is different.
[0017]
Further, the number of mold boxes provided in the upper and lower two stages is also appropriate regardless of the transfer means of each mold box. Accordingly, the number of each tofu heating step, tofu ripening step, discharge step and washing step is also appropriate. Furthermore, the apparatus of the discharge | emission process, the take-out process of a tofu block, and a washing | cleaning process is also arbitrary.
[0018]
The mold box may be an elongated mold box, and a width of about 30 cm or less is optimal. The material of the electrode side plate is not limited.
[0019]
【The invention's effect】
According to claim 1 of the present invention, since the mold box is a two-stage circulation transfer, it can be installed in a narrow place, and by using an elongated mold box, electric heating can be performed uniformly and quickly, and a homogeneous tofu can be obtained. It is obtained.
