[0002] Tofu is a kind of food with rich nutrition and long history. The public's love for tofu has driven the advancement and development of tofu making process. Coagulation molding is one of the main production processes of tofu, that is, under the joint action of heat and coagulant, bean flower (or called tofu brain) or soybean milk is coagulated into a gel body containing a large amount of water-tofu.

[0003] There are various devices for coagulating and shaping tofu, for example, the utility model patent with publication number CN222583623U discloses an automatic tofu shaping machine, which adopts a brand-new intelligent control system to control the cooperative operation of the filtering device, the heating device one, the control valve, the oil cylinder one, the oil cylinder two, and the heating device two, etc. The well-grounded soybean milk is first subjected to filtering treatment under the action of the filtering device, then the completely filtered soybean milk is subjected to heating and boiling treatment in the soybean milk storage tank by the heating device one, then the boiled soybean milk is agglomerated in the shaping box and subjected to extrusion treatment by the pressing plate under the action of the oil cylinder one, so that the soybean milk is coagulated into shaped tofu in the shaping box, finally the shaped tofu is pushed out of the shaping box by the push plate under the action of the oil cylinder two, and the shaped tofu is manually moved to the conveying mechanism to be conveyed away, thereby realizing mechanized tofu shaping treatment operation, replacing the traditional manual operation, improving the sanitary standard, reducing the labor intensity, improving the production efficiency, and ensuring the product quality. For another example, the utility model patent with publication number CN220571525U discloses a tofu dehydration shaping device, which comprises a base, a plurality of support rods are fixedly connected to the upper end of the base at the four corners, a support table is fixedly connected to the top end of the support rods, a spring hole is formed in the support table, a threaded rod is arranged at the upper end center of the support table, and a handle is fixedly connected to the upper end of the threaded rod. The shaping device is provided with a screw rod, the distance between the support table and the support plate can be adjusted by rotating the handle, so that the compression degree of the compression spring is adjusted, thereby realizing the adjustment of the compression force of the compression block on the tofu, and the first rotating rod and the second rotating rod are arranged, the pull rod is only needed to be pulled and placed into the second placing groove, the first rotating rod and the second rotating rod are controlled to move rightward at the connection position, the compression table is pushed downward by the pushing force of the compression spring, the compression block is compressed to dehydrate the tofu, and the operation is simple, convenient and labor-saving.

DETAILED DESCRIPTION

[0030] Reference Figure 1 and Figure 2The application discloses a tofu coagulation and forming equipment, which comprises a forming frame (or forming die) 1, a forming bottom plate 2 and a forming top plate 3. The forming frame is annular, open at the upper and lower ends, vertically arranged, and can be fixedly connected at the head and tail by a plurality of vertically arranged vertical plates or integrally formed. The forming bottom plate is horizontally arranged in the forming frame and used for supporting raw materials (for example, tofu brain) and formed tofu during tofu forming production. The profile edges of the forming bottom plate are vertically and slidingly matched with the inner walls of the forming frame (for example, a sliding matching gap is arranged between each edge of the forming bottom plate and the side wall of the corresponding side of the forming frame), so that the forming bottom plate can slide up and down in the forming frame. The forming bottom plate is densely provided with bottom plate water outlet holes 4 penetrating through the plate surface in the up-down direction and used for draining water during tofu forming. The forming top plate is parallel to the forming bottom plate. The profile edges of the forming top plate are vertically and slidingly matched with the inner walls of the forming frame (for example, a sliding matching gap is arranged between each edge of the forming bottom plate and the side wall of the corresponding side of the forming frame), so that the forming top plate can slide up and down in the forming frame and can be taken out from the forming frame and used for pressing and forming the raw materials together with the forming bottom plate.

[0031] The cross section of the forming frame is preferably rectangular, the cross section of the internal space of the forming frame is also rectangular, correspondingly, the forming bottom plate and the forming top plate are both rectangular plates and have the same shape and size, and the forming frame has a certain height, for example, 10-20 cm, so that the formed tofu is in the shape of a cuboid, facilitating subsequent cutting processing.

[0032] The bottom plate water outlet holes are preferably arranged and distributed in a longitudinal and horizontal regular manner on the forming bottom plate. Adjacent rows of the bottom plate water outlet holes can be arranged in alignment or staggered. The diameter of the bottom plate water outlet holes is preferably 0.5-0.6 mm, for example, 0.5 mm or 0.6 mm, and the distance between any adjacent two bottom plate water outlet holes is preferably 1-1.1 mm, for example, 1 mm or 1.1 mm. In this way, smooth drainage during tofu forming can be ensured, and the friction of the forming bottom plate is reduced to the minimum. After the tofu is formed, the formed tofu is dragged out of the forming frame by the forming bottom plate, and the formed tofu can be slid on the forming bottom plate to the next process (for example, the cutting process), so that the soft tofu is not broken, which is helpful for the realization of automatic production of tofu and facilitates cleaning.

[0033] The inner wall of the forming frame is preferably provided with a horizontally inwardly extending bottom plate bracket 5 for positioning the forming bottom plate in the forming frame. The bottom plate bracket is an annular plate (rectangular in cross section) extending inwardly from the inner wall of the forming frame, or a rectangular plate extending inwardly at intervals on at least one pair of opposite inner walls of the forming frame. The bottom plate bracket is preferably provided at the lower part of the forming frame to provide sufficient space for tofu forming in the forming frame.

The distance between the outer edges of the opposite sides of the top plate frame positioning plate is greater than the distance between the inner walls of the corresponding opposite side walls of the forming frame. In this way, when the top plate frame and the forming top plate fixed to the bottom surface thereof are placed in the forming frame from top to bottom, the top plate frame positioning plate can be placed on the top surface of the forming frame from top to bottom, thereby limiting the depth of the forming top plate entering the forming frame, preventing the forming top plate from entering the forming frame too deeply and squeezing out the raw materials from the bottom plate drain holes or crushing the tofu during tofu forming.
