Description

Technical Field

[0001] The utility model relates to the technical field of wine brewing, in particular to a mold for koji material feet capable of simulating manual stepping on koji. Background Art

[0002] A crucial step in the winemaking process is koji making. This involves preparing the raw materials (wheat, barley, peas, etc.) for the koji block in a suitable proportion. After the koji is tempered and ground, the water content is determined according to a calculated ratio. After the koji and water are mixed evenly, the mixture is placed into a mold and pressed to form a koji block, which then enters the next step, incubation. Traditionally, koji making involves manual treading by a person of appropriate weight. Repeated treading gradually homogenizes the koji in the mold, transforming it from loose to dense, ultimately forming a koji block. The advantage of this traditional method is that the repeated treading, similar to kneading dough, effectively homogenizes the koji and achieves a uniform internal density, facilitating uniform microbial growth during subsequent incubation, effectively reducing variations in koji consistency. While manual treading offers many advantages, it inevitably suffers from low production efficiency. Consequently, the modern winemaking industry currently relies on mechanical koji making devices to produce koji blocks. The mechanical koji-making device compacts the koji material entering the mold on the assembly line through several pressings to form koji blocks that can enter the culture process. The mechanical koji-making device has the advantages of high efficiency and low cost, but the internal koji material uniformity and consistency of the tightness and density of the pressed koji blocks are not as good as those produced by manual pressing, which can easily lead to large fluctuations in the culture quality of the koji blocks.

[0003] A patent document in the Chinese Patent Database, with application number CN202110779640.7 and titled "A device for stamping koji with lees that mimics the human foot's stamping," discloses a technical solution that utilizes a stamping block driven by a stamping mechanism to stamp the koji material. The stamping block that directly contacts the koji material is a curved plate. While this technology proposes the concept of mimicking human foot stamping, the stamping block is structurally different from a human foot, and therefore cannot replicate the effects of manual stamping.

[0011] The main features of the present invention are as follows: A foot mold body that resembles the sole of a human foot is produced based on the principle of bionics. The foot mold body is sequentially provided with toes, soles, arches, and heels. The convex heels and soles form a strong stepping area for the bent material, while the concave arches can form a buffer zone for the bent material. In particular, the toe column can perform multi-point dispersed weak stepping on the bent material to form a bent material relief area to avoid local excessive extrusion and hardening. As the bent mold moves, the strong stepping area, buffer zone, and relief area constantly change positions, applying a homogenization treatment to the bent material similar to the effect of repeatedly kneading dough, thereby achieving good homogenization of the internal structure of the bent block and a high degree of consistency. The use of the present invention can greatly improve work efficiency and reduce production costs while retaining the advantages of manual stepping on the bent material.

DETAILED DESCRIPTION

[0018] See Figure 1-Figure 3 The foot mold of the present invention is used to perform anthropomorphic stepping on the curved material contained in the mold. The foot mold highly simulates the structure of the human foot, and its working principle and effect are completely different from the foot molds in the prior art. The foot mold includes a stepping rod 1, the upper part of the stepping rod is connected to the driving mechanism, and the lower part of the stepping rod is connected to the foot mold body. The foot mold body includes a bionic skeleton 9, an elastic jacket 10, a toe post frame 7 and a toe post 4. The two ends of the bottom of the bionic skeleton are a convex sole part 9-1 and a heel part 9-3, and the middle part is a concave arch part 9-2. The arch part smoothly connects the heel part and the sole part. The bionic skeleton is covered with an elastic jacket 10. The bionic skeleton is equivalent to the bones of the human foot, and the elastic jacket is equivalent to the skin of the human foot. The toe post frame used to install the toe post is fixed to the upper part of the bionic skeleton by two half hoops 11. The toe post frame is fixed to one half hoop, and the toe post frame extends toward the sole part. A toe post hole is provided at the front end of the toe post frame, and a toe post is installed in the toe post hole. The upper part of the toe post is fixed to the toe post frame via a top screw. A spring 6 is provided at the core of the toe post, and a rubber sleeve 5 is covered on the outside of the spring. The structure of the toe post gives it a certain elasticity, the purpose of which is to simulate the natural swing and up and down flexion and extension of the toes during the stepping process, so that the curved material can be stepped on more carefully. The number of toe posts is preferably 3-6. A connecting flange 2 is provided corresponding to each other at the lower part of the stepping rod and the upper part of the foot mold body. The two connecting flanges are connected by bolts. An adjustment pad 3 is provided between the two connecting flanges. By changing the thickness of the adjustment pad, the stepping depth of the foot mold can be fine-tuned.

[0019] The working principle of the present invention is as follows: when the foot model body steps on the curved material, the convex heel and sole areas exert strong pressure on the curved material, while the concave arch area can form a buffer zone for the curved material. Under the pressure of the heel and sole areas, the curved material moves toward the arch area. During the continuous displacement and stepping process of the foot model, the curved material is uniformed by the local displacement of the curved material. The above-mentioned stepping process is similar to kneading dough, and the curved material is repeatedly squeezed in multiple directions to fully uniformize the curved material structure. The elastic toe post acts as a human toe. During the stepping process, the toe post performs multiple weak steps on the curved material, which can form a de-stressing area for the curved material, avoid excessive hardening of the local curved material, and promote the consistency of the density of the curved material.

[0020] See Figure 4 The utility model is used in pairs when working. The motor 13 fixed on the top platform of the right pillar 18 drives the two cams to rotate, and the cam 14 alternately contacts and presses the pressure rod 1, which drives the foot mold body to move, imitating the alternating stepping of artificial feet, and coordinating with the displacement of the mold 12 to realize the anthropomorphic stepping of the curved material, so as to achieve the purpose of good uniformity and high consistency of the internal structure of the curved block.

[0021] This utility model Figure 4 The pressure rod 1 is provided with a pressure head 15 at its top, and a ball and a spring are installed on the pressure head. Both are installed in the blind hole at the top, and only a part of the ball is exposed. When the cam 14 applies pressure on the pressure rod 1, unnecessary friction between the two can be reduced.

[0022] See Figure 4 The present invention incorporates a spring 17 mounted on the pressure rod. This spring is restrained by upper and lower limit sleeves 16, providing a restoring force when the cam leaves its downward limit position. The limit sleeves 16 are secured to a crossbeam 19, through which the pressure rod 1 passes. The crossbeam 19 is secured to left and right support pillars 18, which provide stable support for the entire device.
