Description

Technical Field

[0001] The invention relates to the technical field of soybean husk processing, and in particular to a soybean husk frying production device and process. Background Art

[0002] Technical status: Bean curd skin is a kind of protein film condensed from soybean milk, which has a very high edible value. Due to its excellent puffing effect, it is fresh, fragrant and crispy after frying, and has become a new star in the catering snack industry.

[0003] Since manual operation is extremely time-consuming and labor-intensive, and the unit output is extremely low, people in the industry are currently actively developing mechanical processing equipment, which can only unilaterally solve the problem of manual operation requiring workers to stand in front of the oil pan.

[0004] At present, the fried soybean skin products of the same type are all fried by simulating manual clamping of the soybean skin and rotating it for frying, and the frying is realized by rotating the shaft. Since it is very fragile after frying and puffing, and the clamp is completely wrapped after the volume expands after puffing, this requires the clamp to be very short to ensure that it is not damaged when the skin roll is unloaded, so that the manual labor of soybean skin frying has not been completely liberated, low efficiency and large investment still restrict the development of the industry, and the contradiction between supply and demand cannot be solved. In the prior art, when the fried soybean skin is cut, it needs to be placed in a moisture-returning room, which is easy to make the fried soybean skin regain moisture as a whole, resulting in a decrease in taste, and it is easy to accumulate water vapor inside, resulting in a shortened shelf life of the product. In the production process, the existing soybean skin frying equipment of the same type can only roll the soybean skin into a roll, and the winding is only a single skin and a single roll, and only one roll can be produced at a time, and the next roll can only be entered after the process of each roll is completed.

DETAILED DESCRIPTION

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] Embodiment 1

[0046] like Figure 1-12 The soybean skin frying production device shown in the figure includes a frying box 1, which is composed of a frying box body and a vertical plate at the bottom. The frying box 1 is rotatably connected to a plurality of sprockets 5, on which chains 4 are arranged. One group of the sprockets 5 is rotatably connected to a sprocket motor 24, and the sprocket motor 24 can drive the chain 4 to move through the sprocket 5. The chain 4 is connected end to end to form a closed loop, so that the chain 4 can form a unidirectional closed loop movement when moving.

[0047] At least one set of heaters 18 is fixed to the bottom area of ​​the frying box body of the frying box 1, and a mesh plate 19 is fixed to the upper area of ​​the heater 18. The mesh holes of the mesh plate 19 can prevent the soybean oil skins that accidentally slide down from falling onto the heater 18, and can also facilitate picking up and prevent the soybean oil skins that sink into the oil from being fried for a long time and contaminating the oil.

[0048] The frying box body part of the frying box 1 is provided with a vertical cutter 21 in the area after the chain 4 moves out of the oil liquid level in the moving direction. A rack 28 is provided on one side of the vertical plate part of the frying box 1 close to the vertical cutter 21. The frying box body part of the frying box 1 is provided with an air blowing pipe 20 between the vertical cutter 21 and the moving route of the chain 4. The air blowing pipe 20 is used to blow air to the fried soybean oil skin to accelerate oil drainage, reduce production costs, and quickly cool down the fried soybean oil skin to avoid economic losses caused by product discoloration. The vertical cutter 21 can realize the rotation of the gripper 11 with the assistance of the rack 28, so that the fried soybean oil skin is first rolled into a roll, and then the vertical cutter 21 smoothly completes the cutting of the fried soybean oil skin.

[0049] The frying box body of the frying box 1 is also fixed with a rehumidification box 2, and the upper and lower parts of the rehumidification box 2 are in an open state, which is convenient for the chain 4 to drive the soybean oil skin to move, and the vertical cutter 21 is completely located in the rehumidification box 2. The rehumidification box 2 is also provided with an auxiliary hole 22 and an observation hole 23. The auxiliary hole 22 is used to externally connect to an air source containing water vapor, and the observation hole 23 is convenient for observing the soybean oil skin passing through the rehumidification box 2. The rehumidification box 2 can make the soybean oil skin after frying contact with water vapor only on the surface and soften, which is convenient for cutting, while keeping the inside crispy, avoiding the deterioration of the product taste, and can also improve the product yield rate and make the product adapt to multiple handling.

[0050] Specifically, when the fried soybean skin enters the moisture-retention box 2, the internal heat still radiates outwards, and the outermost layer of the fried soybean skin enters a high-humidity environment, and the mist quickly condenses on the surface of the outer layer of the soybean skin roll (commonly known as moisture absorption), which provides the fried soybean skin with the characteristics of being soft on the outside and crispy on the inside when unloading, ensuring the unloading conditions required for the unloading process. Moreover, after unloading, the residual heat of the fried soybean skin is used to dissipate the moisture of the outermost layer of the fried soybean skin, so as to meet the requirements of subsequent processes.

[0051] The frying box 1 is located on one side of the vertical plate of the frying box 1 in the downward moving direction of the chain 4 and away from the frying box 1. It is rotatably connected to a screw rod 17, and the lower end of the screw rod 17 is fixedly connected to a power mechanism, which adopts a motor. The screw rod 17 is rotatably connected to a tray 16 that can only slide up and down. The vertical plate part of the frying box 1 is fixedly connected to the third cylinder 12, and the suction cup 13 is fixedly connected to the working axis of the third cylinder 12. The moving range of the suction cup 13 can cover the tray 16. The tray 16 can store the soybean oil skin to be processed for at least one time to be sucked by the suction cup 13, which can reduce the frequent manual addition of soybean oil skin to be processed, avoid waste of labor, and reduce the risk of contamination of the soybean oil skin to be processed.

[0052] Furthermore, in order to better serve production, limit sensors are set at the upper and lower ends of the screw rod 17 to prevent the tray 16 from moving out of the working area. A sensor for material supply is set on the tray 16 to sense the amount of soybean skin to be processed on the tray 16. When the soybean skin to be processed is missing, a signal can be sent in time to stop the device and sound an alarm. A material position sensor is set between the tray 16 and the suction cup 13 to facilitate sensing the soybean skin to be processed on the tray 16 and picking it up by the suction cup 13. The three groups of sensors are connected to the controller of the device through signal lines, and corresponding controls are performed respectively by the controller.

[0053] At least one auxiliary block is fixedly connected to the chain 4, and the auxiliary block is rotatably connected to a corresponding rotating seat 27. A gear 26 is connected to the rotating seat 27 on the side of the vertical plate close to the blasting box 1, and a clamping hand 11 is hinged on the side of the vertical plate of the rotating seat 27 away from the blasting box 1. The clamping hand 11 is divided into two parts, which are hinged to the rotating seat 27 at the hinge point, and an elastic member is provided at the hinge of the clamping hand 11 for resetting the clamping hand 11 after opening it, so as to ensure that the clamping hand 11 maintains the clamping force.

[0054] Furthermore, in order to save space, the elastic member may be a torsion spring, and the torsion spring is located at the hinge position of the clamping hand 11, so that the clamping hand 11 can be flexibly and conveniently driven to close the clamping hand 11 after opening, and continuously provide clamping force.

[0055] Furthermore, in order to better enable the gripper 11 to move with the chain 4 and prevent the gripper 11 from shaking, a track 30 that matches the chain 4 is fixed on the blasting box 1.

[0056] Furthermore, in order to better facilitate the unloading of the clamped material after the clamping hand 11 is closed, the clamping part of the clamping hand 11 is a conical long rod and forms a conical smooth surface, which can reduce the unloading resistance during unloading and improve production efficiency and product quality.

[0057] A sensor 29 is also provided on the vertical plate of the frying box 1. The sensor 29 is located in the vertical downward moving section of the chain 4. The sensor 29 can cooperate with the clamping hand 11. The frying box 1 is fixedly connected with a fourth cylinder 15. The working shaft of the fourth cylinder 15 is fixed with a recessed block 14. The recessed block 14 can cooperate with the clamping hand 11 and make the clamping hand 11 open. When the clamping hand 11 moves with the chain 4 to make the sensor 29 work, the chain 4 stops moving. At this time, the recessed block 14 is pushed out by the fourth cylinder 15 to make the clamping hand 11 open, ensuring that the opening range of the clamping hand 11 after opening is within the moving range of the suction cup 13, so that the soybean oil skin adsorbed by the suction cup 13 can enter the clamping area of ​​the clamping hand 11.

[0058] Specifically, the sensor adopts a proximity switch. The proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the action distance, the switch can be activated without mechanical contact or applying any pressure, thereby driving DC electrical appliances or providing control instructions to a computer (PLC) device. It has the characteristics of a travel switch and a micro switch, as well as sensing performance, and has reliable operation, stable performance, fast frequency response, long service life, strong anti-interference ability, and is waterproof, shockproof, and corrosion-resistant.

[0059] Furthermore, in order to better enable the suction cup 13 to deliver the soybean oil skin into the open area of ​​the gripper 11 and ensure that the gripper 11 is in an open state of being opened up and down, a correction rod 25 is also provided on the frying box 1. The correction rod 25 can ensure that the gripper 11 avoids swinging left and right when following the movement of the chain 4, so that the sensor 29 can accurately sense the gripper 11, and then when the sensor 29 is working, the correction rod 25 can make the gripper 11 smoothly turn into an open state of being opened up and down under the action of the concave block 14.

[0060] The vertical plate portion of the frying box 1 is located in the vertical upward moving direction of the chain 4. The frying box 1 is rotatably connected to a plurality of longitudinal cutter discs 3, and the longitudinal cutter discs 3 are connected to corresponding cutting motors 9 that provide cutting power.

[0061] The upper end of the vertical plate part of the frying box 1 is hinged with an upper frame 7, and the upper frame 7 is rotatably connected to a plurality of horizontal knife discs 31, and the horizontal knife discs 31 are connected to corresponding cutting motors 9 that provide cutting power. The upper frame 7 is also fixedly connected to a first cylinder 8, and the first cylinder 8 can adjust the angle between the upper frame 7 and the frying box 1, thereby adjusting the working state of the horizontal knife disc 31.

[0062] The frying box 1 is slidably connected to the unloading plate 6, and a second cylinder 10 capable of reciprocating movement is connected below the unloading plate 6. The unloading plate 6 is located below the transverse knife disc 31. A through groove capable of cooperating with the transverse knife disc 31 is provided on the unloading plate 6. A clamping rod 41 is fixedly connected to the side of the unloading plate 6 away from the longitudinal cutter 3. When the clamping hand 11 moves to the top of the unloading plate 6 following the chain 4, the second cylinder 10 drives the unloading plate 6 to unload the soybean oil skin on the clamping hand 11 with the cooperation of the clamping rod 41.

[0063] It should be noted that this device is a frying equipment in the whole production line of soybean oil skin products. After the unloading plate 6 unloads, the processed soybean oil skin falls into the auxiliary transfer equipment on the production line and is transferred to the subsequent process.

[0064] The frying box 1 is also connected with a controller, which is a control system of the automation equipment and is a mature product in the market, and is not shown.

[0065] The sensor 29, the cutting motor 9, the sprocket motor 24, the power motor of the screw rod 17, and the heater 18 are all electrically connected to the controller and controlled by the controller.

[0066] The frying box body of the frying box 1 is also provided with an electronic thermometer, which is also connected to the controller. The electronic thermometer can detect the temperature, thereby preventing the oil temperature fluctuation from affecting the product.

[0067] The first cylinder 8, the second cylinder 10, the third cylinder 12 and the fourth cylinder 15 are all connected to the gas source, and the working states are all controlled by the controller.

[0068] Furthermore, in order to achieve better control, each group of cylinders is equipped with a position-adjustable magnetic switch, which is an accessory of the cylinder and a mature product in the market. The magnetic switch is connected to the controller through a signal line for corresponding control.

[0069] It should be noted that the vertical cutter disc 21, the longitudinal cutter disc 3, and the transverse cutter disc 31 are selected according to the type of the product being produced.

[0070] Further, according to the product type, when the longitudinal blade disc 3 and the transverse blade disc 31 are selected for producing sheet products, the vertical cutter 21 is not installed, and the rack 28 located in the moving area between the chain 4 and the clamping hand 11 entering the oil liquid level is not installed. At this time, after the clamping hand 11 clamps the soybean oil skin, the soybean oil skin is folded in half with the clamping hand 11 as the center folding line due to its own weight. The clamping hand 11 is driven by the chain 4 to enter the oil in the frying box 1 for frying in the state of the whole soybean oil skin folded in half. The soybean oil skin is fried. Finally, the gripper 11 is driven by the chain 4 to move to the longitudinal knife disc 3, and the longitudinal knife disc 3 rotates to cut the fried bean curd skin carried by the gripper 11. The chain 4 drives the gripper 11 to continue to move to the transverse knife disc 31 area. The transverse knife disc 31 is adjusted to the upper frame 7 under the action of the first cylinder 8 to cooperate with the gripper 11, and the second cylinder 10 drives the unloading plate 6 to move, so that the transverse knife disc 31 completes the cutting of the fried bean curd skin carried by the gripper 11, and finally the bean curd skin is formed into a sheet product.

[0071] Specifically, the soybean oil skin is in a folded state with the gripper 11 as the center fold line. When the sprocket 4 drives the gripper 11 to move and passes through the longitudinal knife disc 3, the soybean oil skin is deflected by its own gravity and contacts the longitudinal cutter 3 to complete the segmentation into strips. The sprocket 4 drives the gripper 11 to continue to move. When the soybean oil skin carried by the gripper 11 is completely laid on the discharge plate 6, the chain 4 stops moving. At this time, the transverse cutter 31 adjusts the cutting distance with the discharge plate 6 under the action of the first cylinder 8, so that the transverse cutter 31 can move relatively in the through groove of the discharge plate 6. At this time, the discharge plate 6 is driven by the second motor 10 to move toward the vertical plate part away from the frying box 1, thereby driving the fried soybean oil skin to separate from the gripper 11 to complete the unloading, and completes the segmentation of the soybean oil skin under the action of the transverse cutter 31, so that the fried soybean oil skin changes from strips to blocks.

[0072] Furthermore, the chain 4 stops moving, and the transverse cutter 31 cooperates with the unloading plate 6 to cut the fried bean curd skin. The sensor 29 sends a signal after sensing that a new set of grippers 11 enters the moving range of the suction cup 3, so that the controller stops the chain motor and performs the feeding action synchronously with the suction cup 3, so as to save production time and improve production efficiency.

[0073] Furthermore, according to the product type, when producing rolled products, when the vertical cutter 21 is selected, the vertical cutter 21 is equipped with a rack 28, and the longitudinal blade disc 3 and the transverse blade disc 31 do not work. The installed vertical cutter 21 can cut the soybean oil skin carried by the gripper 11.

[0074] Specifically, after the gripper 11 grips the soybean skin, the chain 4 drives the gripper 11 to enter the oil in the frying box 1 for frying. The gripper 11 moves with the chain 4, so that the fried soybean skin rubs against the vertical cutter 21 in the rehumidification box 2. At this time, the gear 26 meshes with the rack 28 located on the vertical cutter 21 and rotates, thereby causing the gripper 11 to drive the fried soybean skin to rotate. The length of the rack 28 is greater than the vertical cutter, and the extended end of the rack 28 is located on a side close to the frying box body of the frying box 1, so that the soybean skin can be rolled into a roll before being cut, and then continues to move under the drive of the chain 4 to contact the vertical cutter 21, and is cut by the vertical cutter 21 with the assistance of the rack 28.

[0075] It should be noted that according to the thickness and size of the soybean skin to be processed in our factory, three groups of grippers 11 are evenly distributed on the chain 4, so that the soybean skin frying work can be carried out simultaneously with the coordination of the heater 18 and the moving speed of the chain 4 and the assistance of the sensor 29, thereby realizing a working cycle. After the soybean skin is wound into a roll by the grippers 11, 4 to 5 rolls can be produced at a time with the coordination of the vertical cutter, thereby greatly improving efficiency.

[0076] It should be noted that, due to the different qualities of the soybean oil skin to be processed, such as thickness and size, and the influence of the oil temperature controlled by the heater 18 in the device, the moving speed of the chain 4 and the length of the chain 4, at least one set of grippers 11 can be provided on the chain 4, and it cannot be simply understood that there can only be three sets of grippers 11.

[0077] It should be noted that after the production task of the day is completed, the oil in the frying box 1 is pumped out by the oil pump and then precipitated to avoid excessive impurities affecting product quality.

[0078] Furthermore, the oil pumped out by the oil pump can be stored in a conical oil storage barrel, so that impurities can be easily accumulated when precipitated. The next day, the upper half of the oil in the conical oil storage barrel is taken into the frying box 1, and new oil is added to meet the oil volume required for production.

[0079] Embodiment 2

[0080] Furthermore, when the soybean oil skin enters the frying box 1, the soybean oil skin held by the gripper 11 has not yet expanded and expanded under high temperature, and is very flexible and elastic. Therefore, after the soybean oil skin is rolled up by the gripper 11, the soybean oil skin portion held by the gripper 11 will leave a flexible core and cannot expand at high temperature, which makes it difficult for the cutter to cut. In order to make it easier to cut the rolled soybean oil skin after frying and reduce the appearance of the flexible core, the gripper 11 is further modified on the basis of the first embodiment.

[0081] Specifically, Figure 7-12 As shown, the chain 4 is rotatably connected to the clamping hand 11. In the direction away from the chain 4, the blasting box 1 is fixedly connected with a sliding cylinder 40 that can cooperate with the clamping hand 11. The sliding cylinder 40 is slidably connected to the clamping hand cylinder 32. The sliding cylinder 40 can make the clamping hand cylinder 32 cooperate with the clamping hand 11, and the clamping hand cylinder 32 can make the clamping hand 11 open and close.

[0082] Furthermore, in order to achieve better control, the slide cylinder 40 and the gripper cylinder 32 are connected to the controller through corresponding lines, and are mature products in the market.

[0083] Specifically, the gripper 11 is composed of two parts that are hinged by a central axis 34 and a gripper seat 35 and can be opened and closed up and down. One part is a round rod 111 with a circular cross-section, and the other part is a semi-circular rod 112 with a semi-circular cross-section. The diameter of the round rod 111 is equal to the radius of the semi-circular rod 112. When the semi-circular rod 112 is closed with the round rod 111, the closed contact position of the two rods fits into a straight line, which can make the soybean oil skin fully puffed.

[0084] Specifically, a fixing sleeve 33 with an I-shaped appearance is provided at the place where the clamping hand 11 cooperates with the chain 4, and the chain 4 is fixedly connected to the fixing sleeve 33 by bolts. The fixing sleeve 33 is rotatably connected to the central shaft 34, and the central shaft 34 is fixedly connected to the gear 26 that can cooperate with the rack 28. The central shaft 34 is slidably connected to the clamping hand seat 35, and the clamping hand seat 35 is respectively hinged with a round rod 111 and a semi-circular rod 112 that can cooperate to form a closed state. The shaft end of the central shaft 34 is located at one end of the clamping hand seat and is respectively hinged with the long holes of the round rod 111 and the semi-circular rod 112. A spring 39 for resetting the clamping hand seat 35 is sleeved between the clamping hand seat 35 and the gear 26. An auxiliary plate 38 capable of cooperating with the clamping cylinder 32 is provided on one side of the hinge point 35. When the clamping cylinder 32 is working, it clamps the fixing sleeve 33 and the auxiliary plate 38 respectively, so that the clamping seat 35 slides along the central axis 34 toward the fixing sleeve 33, and synchronously compresses the spring 39, so that the round rod 111 and the semi-circular rod 112 of the clamping hand 11 are in an open state. After the clamping cylinder 32 stops working, the spring 39 can reset the clamping seat 35, and then the round rod 111 and the semi-circular rod 112 are in a closed state, so that the round rod 111 and the semi-circular rod 112 can maintain the clamping force on the soybean oil skin after closing, so as to prevent the soybean oil skin from slipping while following the movement of the chain 4.

[0085] When the chain 4 drives the gripper 11 to move to the vertical cutter 21 area, the gripper 11 rotates in cooperation with the gear 26 and the rack 28, and the gripper 11 clamps the puffed soybean oil skin and completes the segmentation when passing through the vertical cutter 21. At this time, the closed clamping part of the semicircular rod and the round rod of the gripper 11 is very small because the uncut part is very small, and the puffed soybean oil skin remains crispy, so the cutting cracks will also extend to the uncut parts of the puffed soybean oil skin. After unloading, when the heat subsides and the skin becomes crispy again, it will naturally break. This gripping area of ​​the gripper 11 composed of semicircular rods and round rods enables the device to produce multiple rolls at the same time, thereby improving product production efficiency and product yield.

[0086] Furthermore, a counterweight 36 is fixedly connected to the lower side of the gripper seat 35, away from the chain 4. A cavity is provided in the sliding connection area between the gripper seat 35 and the central axis 34, close to the fixed sleeve 33. A steel ball 37 is placed in the cavity. The steel ball 37 cooperates with the counterweight 36 to keep the gripper seat 35 unbalanced, so that when the chain 4 drives the gripper 11 to move, the gripper seat 35 can be avoided from colliding when turning through the sprocket 5. After turning, the gripping direction of the gripper 11 can be kept consistent with the gripping direction during feeding. Under the action of the counterweight 36 and the steel ball 37, when the gripper 11 passes through the rack 28 and rotates and winds under the action of the gear 26, the round rod 111 and the semi-circular rod 112 of the gripper 11 can form a sufficiently suitable winding tightness for the soybean oil skin.

[0087] Specifically, the length of the gripper 11 can be adjusted according to the length of the soybean oil skin to be processed, and is not limited to the previous restriction that the length of the gripper 11 cannot be greater than 15 cm when only a single piece can be produced.

[0088] Embodiment 3

[0089] Further, according to the thickness of the soybean oil skin to be processed, when producing rolled products, the thickness of the soybean oil skin to be processed is usually less than 1 mm. At this time, the rack 28 and the vertical cutter 21 can be used to cooperate to achieve the production and processing of crispy roll products. If the thickness of the soybean oil skin to be processed is greater than 1 mm (including 1 mm), the puffing effect of the soybean oil skin after rolling up becomes poor, and it is not suitable for the production of crispy roll products. Based on the second embodiment, further changes are made.

[0090] Specifically, Figure 7-12 As shown, at this time, the vertical cutter 21 is removed, only the rack 28 is retained, and a pressure plate 42 is installed to enable the gripper 11 to fry the bean curd skin and perform subsequent processing. The lower end of the pressure plate 42 is located on the mesh plate 19, and the upper end is fixed in the rehumidification box 2 through an auxiliary support, so that the pressure plate 42 maintains a uniform distance from the plane formed by the walking path of the chain 4 carrying the gripper 11.

[0091] When only the rack 28 is retained, the gripper 11 can cooperate with the rack 28 under the action of the gear 26 to roll up the fried bean curd skin. At the same time, with the cooperation of the pressing plate 42, the bean curd skin can be compacted during rolling to form a compact roll product, which is convenient for subsequent marinating production.

[0092] Furthermore, in order to save oil, the pressing plate 42 is evenly provided with mesh holes for filtering oil, so that the excess oil can be drained out when the bean curd skin is rolled after frying.
