Description

Technical Field

[0001] The present invention relates to the technical field of bean curd skin production, and in particular to automatic bean curd skin production equipment and a production method. Background Art

[0002] At present, the production of bean curd skin is still mostly done manually, that is, a mixture of bean curd and water is added to a pot, the mixture is boiled and then left to stand. The bean curd water mixture on the liquid surface will dissipate heat quickly to form a "film", which is the bean curd skin. It is then taken down manually and hung to dry. When the bean curd skin is taken down and hung manually, since the bean curd skin is flat on the bean liquid, it may be broken due to poor control when it is taken down manually, resulting in the bean curd skin not meeting the actual requirements, the quality is difficult to control, and the yield is low. If it is taken slowly, it will be time-consuming and labor-intensive. Manual removal of bean curd skin is inefficient and the workload is large.

[0003] In addition, when the bean water mixture is used up, it needs to be added manually, and the amount of addition is difficult to control, which also wastes manpower. In addition, when there is more bean water mixture in the pot, multiple bean skins can be produced continuously without adding bean water mixture. However, due to the high heat of the bean water mixture, the bean skin forming speed is slow; if an appropriate amount of bean water mixture is added for each bean skin produced, the heating time of the bean water mixture can be reduced, and the time for the bean skin to dissipate heat can also be reduced, thereby increasing the speed of bean skin forming, but this undoubtedly increases the workload of adding the bean water mixture back and forth.

[0004] The invention patent with patent application number CN202111637028.2 in the prior art is a fully automatic double-layer oil skin production equipment, which includes: a shell, a generating device, a mobile forming device, and a filling filling device. The shell is provided with generating devices on the upper and lower parts. The mobile forming device is divided into two layers, the upper mobile forming device is arranged on the upper part of the generating device at the upper end, and the lower mobile forming device is arranged between the two generating devices. The filling filling device is fixed on the inner wall of the shell, and a mobile forming device chute is provided on one side of the shell, and a mobile forming device control chute is provided on the other side of the shell. The generating device includes: a generating trough, a bottom plate, a fixed column, an air inlet pipe, and a grouting pipe. The inner wall of the shell of the invention is provided with groove space required for the mobile forming device to move, so as to avoid the mobile forming device from falling off during the moving process, which affects the overall efficiency. However, the patent does not solve the problem of cumbersome work and large total amount of work such as adding soy milk and taking bean skin back and forth. .

[0005] The utility model patent with patent application number CN202121067836.5 discloses a rotary steel belt type oil bean skin continuous processing device, including a pulp spreading unit, a rotating steel belt heating unit, a residual pulp scraper collection unit, a special drying unit, a cutting unit and a weighing and conveying unit that work in sequence, and also includes a steel belt support and guide unit, a friction barrier strip unit, a steel belt correction unit and a steel belt tensioning unit arranged in the rotating steel belt heating unit, and an aerosol collection unit arranged above the rotating steel belt heating unit. The utility model realizes automated pulp spreading without continuous manual intervention, and realizes uniform thickness and quantitatively controllable pulp spreading; in addition, the production speed can be increased by comprehensively improving the heating tank, the pulp separation mechanism, and the steel belt correction control; through the targeted design of the drying mechanism, the volume of the drying mechanism can be reduced by one-half, and the drying stroke can be reduced by one-third, greatly improving the drying speed, but it does not have the problems of bean skin clamping and drying.

[0006] The utility model patent with patent application number CN201920240804.7 discloses an automated bean curd production equipment, including a sprocket frame, on which a plurality of lower sprockets are movably mounted, a lower bean curd cloth is fixedly mounted on the chain conveyor, and rubber fitting strips are fixedly mounted on both sides of the lower bean curd cloth, an upper sprocket is movably mounted between the two sprocket fixing frames, and an upper bean curd cloth is fixedly mounted on the upper sprocket, the width of the lower sprocket is greater than the width of the upper sprocket, and the upper sprocket can be embedded between the rubber fitting strips on both sides of the lower bean curd cloth, and the heating blower is connected to the air-drying plate through a pipeline. The utility model removes excess moisture in the bean curd to a great extent by squeezing, and then forms the bean curd by applying heat to the upper sprocket and the upper bean curd cloth by the heating blower, thereby ensuring the moisture content of the bean curd and thus ensuring the quality and taste of the bean curd, and at the same time, the gap between the upper bean curd cloth and the lower bean curd cloth can be controlled, thereby producing bean products with different tastes and different types, but the patent does not solve the problems of adding soy milk and hanging bean curd.

Since the bean skin has a certain softness, when the first clamping plate and the second clamping plate abut against the bean skin, part of the bean skin will be located between the first clamping plate and the second clamping plate, and then the cylinder is started, and the cylinder drives the T-shaped slider to move, so that the first clamping plate and the second clamping plate can move relative to each other, thereby clamping the bean skin;

[0033] 2. The cylinder drives the T-shaped slider to move, so as to realize the relative movement of the first clamping plate and the second clamping plate, so as to clamp the bean skin. Then, part of the bean skin is located in the through groove. Since the two sides of the bean skin are open, the bean liquid in the bean skin in the through groove will flow out from both sides to discharge the surplus water. There will be no situation that the bean liquid cannot be discharged in time and the bean skin will be broken, thus ensuring the quality of the bean skin after clamping. At the same time, the clamping area of ​​the bean skin is increased, so that it is not easy to fall off, thus ensuring the stability of clamping and improving work efficiency.

[0034] 3. The first motor reverses to move the sliding plate upward, so that the clamped bean curd can be moved upward. At this time, the electric push rod drives the slide and the lifting rod to move to the back side of the bean curd, and the lifting rod is located in the middle of the bean curd.

Since the amount of pulp added is convenient to control and can be added in small amounts multiple times, the heating time of the bean water mixture and the heat dissipation time of the bean skin can be reduced, thereby further improving the speed of bean skin forming.

[0072] S5, the first motor 3 reverses to realize the upward movement of the sliding plate 5, so that the clamped bean skin can be moved upward, and the electric push rod 14 drives the slide 31 and the lifting rod 30 to move to the rear side of the bean skin, and the lifting rod 30 is located in the middle of the bean skin, and the hydraulic cylinder drives the bracket 2 to move backward, the bean skin and the bar 30 are against each other, and the first clamping plate 7 and the second clamping plate 8 are separated by the cylinder 9, so that the bean skin is placed on the lifting rod 30, and the electric push rod 14 is reset to realize the removal of the bean skin.

[0073] Example 4

[0074] An automatic bean curd production device is similar to the embodiment 1, except that a through groove 81 is provided through the first clamping plate 7 and the second clamping plate 8, the through groove 81 is circular, and the height gradually decreases from the side opposite to the first clamping plate 7 and the second clamping plate 8 to the outside, and the diameter gradually increases from the side opposite to the first clamping plate 7 and the second clamping plate 8 to the outside, such as Figure 7 As shown, while clamping the bean skin, there is too much liquid bean water mixture between the contact surfaces between the bean skin and the first clamping plate 7 and the second clamping plate 8, which needs to be discharged in time. However, if the clamping force of the first clamping plate 7 and the second clamping plate 8 is large, the bean skin will be deformed and even broken in severe cases. If the clamping force of the first clamping plate 7 and the second clamping plate 8 is small, the bean skin will fall off from between the clamping plates during the rising process of the first clamping plate 7 and the second clamping plate 8. Therefore, a through groove 81 is provided, and the bean water mixture between the first clamping plate 7 and the second clamping plate 8 will flow out from the through groove 81. Since the height position of the through groove 81 is gradually reduced and the diameter of the opening toward the outside is gradually increased, the excess bean water mixture can be discharged more quickly.
