Description

Technical Field

[0001] The invention relates to the field of tofu production, and in particular to a double-enzyme whole-soybean tofu production method and an integrated device. Background Art

[0002] Tofu is a nutritious food with a long history. The public's love for tofu has promoted the progress and development of tofu production technology. The main production process of tofu is pulping, that is, making soybeans into soy milk; the second is coagulation, that is, soy milk coagulates into a gel containing a large amount of water under the combined action of heat and coagulant, that is, tofu. Under this process, a large amount of bean dregs and yellow pulp water will be produced, affecting the yield and nutritional indicators of tofu. Tofu contains a variety of trace elements necessary for the human body and rich high-quality protein. It is known as "plant meat". However, when making tofu, the existing process is to filter the beans after grinding them, and then remove the filter residue. The filter residue does not enter the subsequent tofu production, which causes a waste of raw materials and greatly reduces the cellulose content in tofu. At the same time, after filtering, organic sewage such as yellow pulp water is produced. Because the COD of yellow pulp water is about 15,000 to 30,000, and the amount is large and difficult to handle, it brings an economic burden to the production enterprises and causes a certain impact on the surrounding environment.

[0074] The implementation principle of the embodiment of the present application is:

[0075] Before starting work, turn on the wall breaker 12 and the motor 35. The action of the motor 35 drives the rotating frame 21, the mounting block 18, and the swing plate 17 to swing, fanning the air, promoting gas flow, and ensuring the internal temperature. At the same time, the rotating frame 21 on the other side is transmitted through the coupling 1 30, the coupling 2 31, the threaded tube 1 32, the sleeve 33, the threaded tube 2 34, etc., so that it rotates periodically, thereby driving the transmission rod 55 and the grinding ring 56 to rotate, thereby realizing the grinding work.

[0076] During operation, the peeled beans are passed through the feeding tube 11 into the packaging tube 13, and the wall is pre-broken by the wall breaker 12 for coarse grinding. Then, they pass through the hopper 14 and the dispersion tube 15 and enter into a plurality of corresponding grinding boxes 28. The bean dregs fall onto the fixed ring 53 through transportation and gravity, and then pass through the hole in the middle of the fixed ring 53 and enter into the space between the fixed ring 53 and the grinding ring 56. With the rotation of the grinding ring 56, they are ground multiple times to achieve corresponding fine grinding. At the same time, the water inlet of the water injection pipe 02 is coordinated to keep the grinding temperature in a stable state, and finally, they are discharged through the transverse pipe 29.

[0077] The discharged soy milk passes through the conducting pipe 24 and the conducting tube 25 into the separation box 36, and then is guided accordingly by the guide plate 37. Part of the soy milk that meets the particle size enters the bottom of the filter rack 39, and then enters the steamer 46 through the pipeline for steaming. The hot air generated by the steaming is discharged through the steam pipe 47, the interception box 49, and the discharge pipe 48. The steamed soy milk enters the outside through the finished product pipe 03 for the subsequent operation steps and molding.

[0078] The unsatisfactory bean dregs filtered by the filter rack 39 are collected in the temporary storage chamber 42, and then lifted by the lifting pump through the reflux pipe 26 and returned to the grinding box 28 for secondary grinding to ensure the overall particle size and thus ensure the production of residue-free tofu.
