Description

Technical Field

[0001] The utility model relates to the field of soy sauce production equipment, in particular to a soybean raw material steaming device for soy sauce production. Background Art

[0002] Soybean paste, also known as soybean sauce or bean paste, is a traditional Chinese condiment. The origin of soybean paste can be traced back to ancient China, especially in the Western Han Dynasty. According to historical records, soybean paste was initially made from raw materials such as soybeans and flour through natural fermentation. In the long historical process, the production techniques of soybean paste have been continuously developed and improved, forming unique production processes and flavor characteristics. The production process of soybean paste mainly includes multiple steps such as material selection, cleaning, soaking, steaming, fermentation, and seasoning. During the steaming process of soybean paste, a soybean raw material steaming device is required.

[0003] In the existing soybean raw material steaming device for soybean paste production, the soaked soybean raw materials are usually directly poured into the steaming device for steaming. It takes a long time for the soybean raw materials to be completely steamed, and the steaming efficiency is low. For example, the utility model patent with the application number 201920568481.4 discloses a soybean raw material steaming device for soybean paste production. Through the movable pressing plate, it can ensure that the soybeans are completely immersed in water after soaking, thus ensuring the soaking quality and efficiency of the soybeans.

[0004] However, when this device steams the soybean raw materials, it directly steams the whole soaked soybeans. The time required for the inside of the soybeans to be completely steamed is long, and the steaming efficiency is low. In addition, after the soybean raw materials are input into the steaming box, they remain stationary and cannot be turned during the steaming process, which easily causes uneven heating of the soybeans and uneven steaming degree of the soybeans.

[0005] Therefore, it is necessary to develop a soybean raw material steaming device for soybean paste production to address the above-mentioned defects. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a soybean raw material steaming device for soybean paste production, which can crush the soybean raw materials and then steam them, improving the steaming efficiency of the soybean raw materials.

[0026] In a specific implementation manner, as Figure 1 and Figure 2As shown in the figure, it includes a steaming tank 1, a first crushing component and a stirring component. A heat preservation layer 2 is nested on the outer wall of the steaming tank 1. A resistance wire 3 is fixedly connected in the interlayer between the steaming tank 1 and the heat preservation layer 2. The top of the steaming tank 1 is detachably connected with a tank cover 4.

The stirring component includes stirring paddles 10. The number of the stirring paddles 10 is several groups and they are fixedly connected to the outer wall of the rotating shaft 5 below the sieve plate 8 at intervals.

[0027] The first driving unit drives the rotating shaft 5 and the cylinder shaft 6 to rotate in opposite directions, so that the cylinder shaft 6 drives the rolling roller 7 to rotate, and the rotating shaft 5 drives the sieve plate 8 to rotate in the opposite direction, realizing the relative movement of the rolling roller 7 and the sieve plate 8, thereby rolling the soybean raw materials on the sieve plate 8, crushing the soybean raw materials, and falling into the steaming tank 1 through the filtering holes 9 on the sieve plate 8 for steaming. At the same time, the rotation of the rotating shaft 5 can drive the stirring paddles 10 to rotate, stirring the soybean raw materials in the steaming tank 1. Thus, the soybean raw materials are crushed and then steamed, and the soybeans are turned during the steaming process, so that the soybeans are heated evenly, ensuring that the steaming degree is consistent, and improving the steaming efficiency of the soybean raw materials.

[0028] In a specific embodiment, the first driving unit includes a first motor 11, a first bevel gear 12, a second bevel gear 13 and a third bevel gear 14. An installation box 15 is fixedly connected to the top surface of the tank cover 4.

[0038] Through the arrangement of the support seat 23, the rotating shaft 5 can be supported to prevent the rotating shaft 5 from shifting, thereby reducing the stability of the device.

[0039] Working principle of the present utility model: When the soybean raw material cooking device for the production of soybean paste of the present utility model is in use, the soaked soybean raw materials are conveyed into the crushing box 16 through the feed inlet 18. The soybean raw materials fall between the two squeezing rollers 17 via the guide plate 21. The second motor 19 is turned on, and the second motor 19 drives the connected gear 20 to rotate. This gear 20 drives another meshing gear 20 to rotate, causing the two squeezing rollers 17 to rotate in opposite directions, capable of squeezing and crushing the soybean raw materials falling between the two squeezing rollers 17, and conveying them to the sieve tray 8 below. The first motor 11 is turned on, and the rotation of the first motor 11 drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the second bevel gear 13 and the third bevel gear 14 to rotate in opposite directions, realizing the reverse rotation of the rotating shaft 5 and the cylinder shaft 6, further driving the rolling roller 7 and the sieve tray 8 to rotate in opposite directions, realizing the relative movement between the rolling roller 7 and the sieve tray 8, thereby rolling the soybean raw materials falling on the sieve tray 8, further crushing the soybean raw materials, and falling into the cooking tank 1 through the filter holes 9 on the sieve tray 8 for cooking.
