Description

Technical Field

[0001] This utility model relates to the field of fermentation device for fermented bean curd processing, specifically to a fermentation device for fermented bean curd processing. Background Technology

[0002] Fermented bean curd, also known as tofu curd, is a flavorful delicacy made from soybeans through grinding, forming, fermentation, and cultivation. The initial work of making fermented bean curd includes grinding, and the resulting semi-finished product is the tofu we commonly see in daily life. Fermentation is the key step in processing the tofu blocks into fermented bean curd.

[0003] The fermentation process generally includes preliminary preparations (obtaining the fermentation starter), inoculation (combining the starter with tofu blocks), and fermentation (allowing the microbial community to use tofu as a culture medium to modify the tofu). Inoculation, whether in large-scale production in a factory, a small workshop, or home-based production, is almost always done by hand, grabbing a handful of breadcrumbs and swishing the arm to evenly sprinkle the remaining starter onto the tofu blocks in a bamboo basket. While a few factories have the necessary large-scale equipment, widespread adoption in home-based production environments is objectively impractical. This manual, swishing inoculation method cannot guarantee that all tofu blocks in a basket receive an adequate amount of starter. The degree of inoculation directly affects the quality of the fermented tofu. In larger-scale street shops, small workshops, or factory workshops, workers must constantly grab handfuls of starter and swish their arms to sprinkle the starter onto multiple baskets, which is relatively laborious and inefficient. Therefore, this paper proposes a fermentation device for fermented tofu processing. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that the method of using hand-grabbed scraps to sprinkle and adhere to tofu in a bamboo basket for fermentation inoculation results in uneven and ineffective inoculation, which directly affects the quality of the fermented tofu.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a fermentation device for fermented bean curd processing, including a base.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1

[0024] Combined with appendix Figure 1-4 To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a fermentation device for fermented bean curd processing, including a base 1, a bearing groove 2 connected inside the base 1, a support 3 connected above the base 1, a bushing 8 rotatably connected to the top of the support 3, a power mechanism for driving the bushing 8 to rotate connected above the support 3, the power mechanism including a transmission shaft 4, the transmission shaft 4 being rotatably connected to the top of the support 3, a motor 5 rotatably connected downward above the support 3 and cooperating with the transmission shaft 4, a main gear 6 connected to the transmission shaft 4, a secondary gear 7 meshing with the main gear 6 connected to the top of the bushing 8, a feeding pipe 9 connected inside the bushing 8, a collecting funnel 10 connected to the top of the feeding pipe 9, a spray head 15 connected to the bottom of the feeding pipe 9 extending into the support 3, and a swing mechanism for changing the inclination of the spray head 15 connected to the bottom of the feeding pipe 9.

[0025] The starter culture for fermenting fermented bean curd is added through the feeding pipe 9 with the collection funnel 10 and sprayed onto the fermented bean curd through the spray head 15 below. If the starter culture is in solid powder form, similar to bread crumbs, the spray head 15 can be a simple nozzle. If it is a liquid solution like water, the spray head 15 can also be a nozzle with a certain spray pressure. During the inoculation operation, the bamboo basket containing the tofu blocks is placed in the bearing groove 2 on the base 1. After the motor 5 runs, the transmission shaft 4 rotates. Under the action of the transmission module composed of the main gear 6 and the auxiliary gear 7, the bushing 8 carries the feeding pipe 9 to rotate.

[0026] Example 2

[0027] Combined with appendix Figure 1-3 and appendix Figure 5 The swing mechanism includes a support rod 13, which is connected to the bottom of the feeding pipe 9. A convex ring 11 is connected downward to the top of the bracket 3. A sliding groove 12 is connected to the inner side of the convex ring 11. The end of the support rod 13 away from the feeding pipe 9 extends into the sliding groove 12. A support block 16 is connected to the spray head 15. A support block 28 is connected downward to the end of the support rod 13 away from the feeding pipe 9. An electric telescopic rod 17 is rotatably connected between the support block 16 and the support block 28. A telescopic hose 14 is connected between the feeding pipe 9 and the spray head 15. A collection frame 20 is connected to the outside of the base 1. Baffles 19 are connected upwardly around the collection frame 20. Multiple discharge ports 21 are connected to the edge of the collection frame 20.

[0028] A support rod 13 is installed above the spray head 15 on the feeding pipe 9. An electric telescopic rod 17 is mounted on the support rod 13, with its two ends rotating relative to the support rod 13 and the spray head 15, respectively. When the spray head 15 is vertically downward, the electric telescopic rod 17 is in an extended state. When its state changes and it gradually shortens, the spray head 15 at the bottom of the feeding pipe 9 will tilt to one side. The degree of tilt is determined by the extent of shortening of the electric telescopic rod 17. This, combined with the feeding pipe 9 rotated under the control of the motor 5, causes the spray head 15 to... The sprinkled inoculum can evenly and relatively thoroughly cover the tofu in the bamboo basket below, ensuring that each piece of tofu receives sufficient inoculation. A collection frame 20 with a baffle 19 is installed around the base 1. Due to the rotation and feeding process, some of the inoculum may be uncontrollably thrown out of the base 1 due to centrifugal force. In order to prevent these materials from affecting the external environment, the baffle 19 can effectively block and collect these splashed waste materials. Whether these materials are solid particles or liquids, they can be easily discharged from the discharge port 21 at the bottom of the collection frame 20.

[0029] In practical implementation, a bamboo basket containing tofu to be fermented into fermented bean curd is placed in the support groove 2 of the base 1. The motor 5 in the device continuously runs, keeping the feeding pipe 9 and the spray head 15 rotating. The electric telescopic rod 17 also continuously moves repeatedly, causing the spray head 15 to sway between different tilt angles. The range of motion should be reasonably designed, neither too fast nor too slow. The inoculated substrate is fed into the feeding pipe 9 from the upper collection funnel 10. Here, solid special bread crumbs are used. The crumbs gradually descend to the spray head 15, and due to the rotation... Centrifugal force, gravity, and the continuous compression of the material above cause debris to fall off the spray head 15 and onto the tofu blocks below. The electric telescopic rod 17 tilts the spray head 15 to adjust the area covered by the spray head 15 for inoculation, while the motor 5 rotates the tilted spray head 15 to ensure that the area covered by the spray head 15 is inoculated. The continuous adjustment of the electric telescopic rod 17 allows more areas to be effectively inoculated. With the cooperation of both, the tofu blocks in the bamboo basket can be fully inoculated with microorganisms, providing effective quality assurance for subsequent fermentation.
