Description

Technical Field

[0001] This invention relates to the field of soybean product processing equipment technology, and in particular to a double-layer steel belt machine for processing bean curd skin and tofu skin. Background Technology

[0002] In the existing soybean product processing industry, traditional production equipment is usually single-function. For example, a dedicated soybean skin machine can only be used to produce soybean skin, while a dried bean curd stick machine is specifically used to produce dried bean curd sticks. Due to the differences in forming, drying and subsequent processing technology, the two often cannot be completed on the same machine. When production enterprises need to adjust their production plans between different products according to market demand, they usually need to replace the entire machine or carry out cumbersome equipment disassembly and debugging.

[0003] This not only increases the company's equipment procurement costs and site occupancy costs, but also makes production line switchover time-consuming and labor-intensive, seriously affecting production efficiency and capacity flexibility.

[0004] In addition, the existing single-line equipment has low capacity and cannot meet the needs of large-scale production. Furthermore, the residual soy milk in the production process is often directly discharged, resulting in waste of raw materials. Therefore, a double-belt tofu skin steel belt machine is proposed. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a double-layer steel belt machine for dried bean curd skin to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0016] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, by setting up auxiliary components, particularly by using an electric push rod to drive a U-shaped plate to move the first scraper up and down, can flexibly adjust the relative position between the first scraper and the steel belt ring. When producing bean curd sheets, the first scraper can be controlled to press down and adhere to the steel belt, scraping and guiding the bean curd sheets in a specific direction. When producing dried bean curd sticks, the first scraper can be controlled to move up and away from the steel belt, allowing the bean curd sheets to pass smoothly and enter the subsequent rolling or cutting process. This allows the equipment to quickly switch between bean curd sheet and dried bean curd stick production processes without stopping the machine to replace parts or the entire machine, greatly improving work efficiency and equipment versatility, and effectively reducing the operating costs of enterprises.

[0017] Second, this invention utilizes two parallel production components, employing dual steel belt conveyors to operate simultaneously, and is driven independently or synchronously by two first servo motors, thus achieving dual-channel production. This not only significantly increases output per unit time but also ensures the continuity and stability of the production process.

[0018] Third, this invention utilizes a combination of a trapezoidal box, a filter plate, and a pump body to recycle the filter components. This allows residual soy milk on the steel belt ring to be scraped off and collected by a second scraper. After impurities are filtered out by the filter plate, the soy milk is pumped back into the T-shaped pipe by the pump body through the T-shaped connecting pipe for reuse. This effectively reduces raw material waste, lowers production costs, and meets the requirements of environmental protection and energy conservation.

[0019] Third, by integrating a drying mechanism and a drying component, the bean curd sheets are dried by heating plates and heating tubes, and then further dried and cooled by natural air drying through a transmission mechanism that drives the first and second belts. This graded processing method ensures that the product has a suitable moisture content, good forming effect, and improves the taste and quality of the final product.

The output shaft drives one of the first rollers 13 to rotate, which in turn drives the steel belt ring 14 to rotate. The other first roller 13 assists in the rotation of the steel belt ring 14. The bean curd sheets produced on the two production components 1 move relative to each other. While the bean curd sheets on the steel belt ring 14 of the other production component 1 are manually placed onto the third belt ring 113, the bean curd sheets on the steel belt ring 14 of the one production component 1 are scraped off by the first scraper 34 and then manually placed onto the guide plate 33 and the third belt ring 113. The output shaft of the second servo motor 117 drives one of the fourth rollers 112 to rotate, which in turn drives the third belt ring 113... The third belt 113 rotates, and another fourth roller 112 assists the third belt 113 in rotating. The third belt 113 moves the bean curd sheets and heats them through the heating plate 115 and heating tube 116. The heating tube 116 is used when the heating plate 115 is unusable. When the third belt 113 moves the bean curd sheets, the bean curd sheets are manually moved to the second belt 23 and the first belt 22 for further cooling and shaping. One of the fourth rollers 112 rotates through the third connecting rod 266, which drives the chain ring 260 to rotate through the first sprocket 261. Simultaneously, the second sprocket 262 and the third sprocket 263 rotate in opposite directions. The second sprocket 262 drives one of the third rollers 25 to rotate via the second connecting rod 265. The third sprocket 263 drives one of the second rollers 24 to rotate via the first connecting rod 264. One of the third rollers 25 drives the second belt 23 to rotate, and the other third roller 25 assists the second belt 23 in rotating. One of the second rollers 24 drives the first belt 22 to rotate, and the other second roller 24 assists the first belt 22 in rotating, thereby ensuring the stability of bean curd skin production. Then, the produced bean curd skin is cut.

[0040] When it is necessary to produce dried bean curd sticks, the relevant personnel activate the electric push rod 31. The piston rod of the electric push rod 31 drives the U-shaped plate 32 to move upward, the U-shaped plate 32 drives the guide plate 33 to move upward, and the guide plate 33 drives the first scraper 34 away from one of the steel belt rings 14. Then, the relevant personnel evenly spray soy milk onto the steel belt ring 14 through the second through hole 8 on the first servo motor 18. Then, the hot water on the F-shaped tube 16 is sprayed out through the first through hole 7 to heat the soy milk on the steel belt ring 14 to form a skin. The output shaft of the first servo motor 18 drives one of the first rollers 13 to rotate. One of the first rollers 13 drives the steel belt ring 14 to rotate, and the other first roller 13 assists the steel belt ring 14 in rotating. The bean curd sheets produced on production component 1 move relative to each other. The bean curd sheets on the steel belt rings 14 of the two production components 1 are manually placed on the third belt ring 113. The output shaft of the second servo motor 117 drives one of the fourth rollers 112 to rotate. One of the fourth rollers 112 drives the third belt ring 113 to rotate. The other fourth roller 112 assists the third belt ring 113 in rotating. The bean curd sheets on the third belt ring 113 move and are heated by the heating plate 115 and the heating tube 116. The heating tube 116 is used when the heating plate 115 is not available. Then, as the third belt ring 113 moves the bean curd sheets, the produced bean curd sheets are cut to obtain dried bean curd sticks.

[0041] The soy milk remaining on the two steel belt rings 14 is scraped off by the second scraper 42 and then flows to the second scraper 42 for filtration. It is then stored in the trapezoidal box 41. The pump body 44 then transfers the soy milk in the trapezoidal box 41 to the T-shaped connecting pipe 40. The soy milk in the T-shaped connecting pipe 40 is then transferred to the T-shaped pipe 17, which facilitates the recycling of the soy milk.
