Description

Technical Field

[0001] The present invention relates to the field of mechanical automation, and in particular to a multifunctional intelligent tofu machine. Background Art

[0002] Tofu, a high-protein product, is universally popular. To make it, soybeans are first soaked in water and then ground in a grinder. The soy milk and dregs are then separated. The separated soy milk is then boiled, brine-cured, and pressed before being made into tofu. The process is laborious and complex, requiring a high level of skilled labor.

[0003] Modern tofu production is mostly done in large factories using large machines, while tofu is handmade in smaller workshops. The tofu we eat in our daily lives is often produced by others, and its safety and health are not well guaranteed. We cannot freely choose the flavor of our tofu to suit our tastes, and users' preferences and individual needs are not well met. Making tofu at home is time-consuming and expensive, making the idea of ​​enjoying homemade tofu seem out of reach. While the popularity of soymilk makers has led to the emergence of numerous tofu-making machines, most are complex and lack intelligence. While some miniaturized tofu machines exist, they still have many shortcomings that require improvement.

[0004] For example, a Chinese patent (publication number CN102204593B) discloses a household tofu machine, but its overall intelligence is low, the quality of tofu cannot be controlled, and the switching between soy milk and tofu production is complicated.

[0005] For example, a Chinese patent (publication number CN102550700B) discloses a tofu machine, which aims to provide a tofu machine with a simple structure, low cost, and small space occupation, but its function is single and cannot be intelligently adjusted.

[0006] In summary, the existing tofu machines cannot control the amount of beans delivered well, nor can they switch between the production of soy milk and tofu. The operation process is complicated and the utilization of raw materials cannot be maximized. Summary of the Invention

The outer shell encases all of these structures, resulting in a simple overall structure, a small footprint, and a high level of intelligence. In specific applications, a controller is also provided, which is communicatively connected to the feeding motor, the opening and closing motor, the slag removal motor, the heating and stirring motor, the first lifting motor, and the second lifting motor.

[0048] The working principle of the present invention is further explained below:

[0049] like Figure 7As shown, the tofu machine has two control modes: app-based remote control and direct touchscreen control. You can choose the appropriate control method to control the multifunctional tofu machine as needed. Both control methods allow you to select tofu specifications and a start time. When the tofu machine starts operating, the feeding mechanism delivers an appropriate amount of soaked beans from the bean storage bin according to the user's selected specifications via a pipe below into the hopper of the soymilk grinding mechanism 2. Once the beans are in, the water adding mechanism 3 automatically adds the appropriate amount of water. The grinding motor then drives the blades to rotate and begin grinding the beans. Once the soymilk is successfully ground, it is transferred to the filter barrel via the lower opening and closing liquid delivery mechanism 4. The motor then drives the screw to rotate, and the pressing platform moves downward as the screw rotates, squeezing the soymilk containing the dregs. The slurry, under pressure and pump suction, seeps out of the tiny pores in the chamber and flows into a water collection device outside the chamber. It is then transferred through a water pump pipe to the heating device for heating and stirring. Simultaneously, the dregs are pressed into bean cakes, which descend as the first lifting platform 7 descends and can be removed from the right side of the machine. After the soymilk slurry is boiled, it is transferred to the brine pressing chamber via a water pump. If the user chooses to make soymilk, the second lifting platform 11 will directly descend below the pores in the chamber, allowing the soymilk to naturally flow out to the liquid collection mechanism, from which the soymilk can be taken out. If the user chooses to make tofu, after the cooked soymilk enters the brine pressing chamber, the machine automatically opens the brine device to prepare the brine. The second lifting platform 11 can be controlled to rotate or move up and down as needed. The top rod of the cam-type screw motion mode conversion mechanism retracts, and the second lifting platform 11 rotates under the rotation of the gear, stirring the brine to fully blend with the soymilk and accelerate its formation. After the soymilk after the brine is formed into tofu pudding, the top rod of the cam-type screw motion mode conversion mechanism pushes forward, and the second lifting platform 11 switches from rotational motion to up and down movement, descending below the pores in the brine pressing chamber. The second pressing platform presses down to squeeze out the water. Finally, the second motion platform descends, and the tofu can be taken out from the left chamber, and the tofu is ready.

[0050] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
