Description

Technical Field

[0001] The utility model relates to the technical field of sweet potato chip processing, and particularly relates to a sweet potato steaming device. Background Art

[0002] Sweet potatoes can be processed into instant sweet potato chips through processes such as cleaning, peeling, steaming, cutting, and drying; because sweet potatoes contain a large amount of complex components such as fiber, in the steaming process, it is generally difficult for large pieces of sweet potatoes to be quickly cooked, which not only significantly increases the production cost for industrial processing, but also the traditional repeated low-pressure long-time steaming will affect the flavor of sweet potato chips. For example, the patent authorization publication number: CN103082239B, a sweet potato chip processing method, belongs to a relatively traditional process, and its processing steps are: "Soaking, soaking the peeled sweet potatoes in clean water at normal temperature in a timely manner, and the time shall not exceed 8 hours; steaming, fishing out the sweet potatoes in the clean water in the above step and putting them into a closed steaming pot in a timely manner for steaming. It is steamed in two steaming pots. First, steam in the first steaming pot. First, steam over high heat until the pressure in the pot reaches 0.02 - 0.04 Mpa and lasts for 2 - 2.5 hours, then steam over low heat until the pressure in the pot reaches 0.01 Mpa and lasts for 1.5 - 2 hours, and then take out the pot and enter the cutting step; after steaming three pots of sweet potatoes alternately in two steaming pots, the second steaming pot is changed to clean water again, and so on alternately." As can be seen from the above, the traditional steaming method not only takes a long time, but also the outer layer of the sweet potato pieces will have a reduced taste after long-time steaming; therefore, in many processes, it is generally necessary to soak the sweet potato pieces in syrup later to improve the taste. However, the above process not only significantly increases the production cost, but also changes the original flavor of the sweet potato chips and reduces the taste experience.

[0026] As Figures 1 to 6 shown, a sweet potato steaming device includes a gas-liquid mixed boiling steaming device 1. The gas-liquid mixed boiling steaming device 1 includes a device body. The device body is provided with a steaming flow cavity 2. The steaming flow cavity 2 is a straight-through long hole structure. In this embodiment, as Figure 2 shown, it can be a wide opening with a length of 90 cm to match the width of the conveyor belt for feeding; an air inlet cavity 8 is provided at the lower part of the steaming flow cavity 2. The steaming flow cavity 2 and the air inlet cavity 8 are communicated through a plurality of ventilation holes 7. In this embodiment, the partition between the steaming flow cavity 2 and the air inlet cavity 8 can be made of a stainless steel punched hole plate, and the punching hole diameter can be selected within 3 mm. The advantage of using a fine hole punched plate is that it can improve the uniformity of the air outlet and reduce the friction on the sweet potatoes in the cavity; an air extraction cavity 3 is provided at the upper part of the steaming flow cavity 2. The steaming flow cavity 2 and the air extraction cavity 3 are communicated through a plurality of air extraction holes 4. In this embodiment, the structure of the air extraction cavity 3 is that the front part is higher than the rear part. The function of this design is that when the gas-liquid mixed boiling steaming device 1 is installed obliquely, the distance from the rear air extraction holes 4 to the liquid surface is reduced, improving the smoothness of air extraction; an air inlet connection port 9 is provided on the air inlet cavity 8; an air extraction connection port 5 is provided on the air extraction cavity 3. When in use, as Figure 6As shown in the figure, it further includes an exhaust fan 26. The exhaust fan 26 can be selected from the 600°C high-temperature fan series of Xinxiang Xima. The air inlet of the exhaust fan 26 is connected to the air extraction connection port 5 through an air extraction pipe 27; the air outlet of the exhaust fan 26 is connected to the air inlet connection port 9 through an air inlet pipe 24. In order to realize the constant-temperature heating of the gas, it further includes a constant-temperature gas heating device 25. The constant-temperature gas heating device 25 is arranged between the air outlet of the exhaust fan 26 and the air inlet connection port 9. The constant-temperature gas heating device 25 can adjust the heating temperature according to the process requirements to provide constant-temperature gas for the gas-liquid boiling and steaming device 1. A liquid return port 6 is arranged on the side wall or the feeding end side of the steaming flow chamber 2. The function of this design is as follows: during use, when high-temperature gas is introduced into the steaming flow chamber 2, the liquid inside will boil, resulting in the loss of liquid in the chamber. Since the sweet potato pieces flow from top to bottom, the setting of the liquid return port 6 is beneficial to quickly supplement the liquid in the chamber. During use, the flow rate of the exhaust fan 26 needs to be adjusted according to the actual production needs to maintain a certain negative pressure in the air extraction chamber 3. It is necessary to prevent too much loss of high-temperature gas due to insufficient negative pressure and also maintain that the high-temperature gas enters the steaming flow chamber 2 and releases heat fully before entering the circulation pipeline to improve energy efficiency.

[0027] During use, high-temperature gas at 250-550 degrees Celsius is introduced into the steaming liquid to promote gas-liquid explosion boiling in the steaming flow chamber 2. The ultra-high-temperature gas-liquid has stronger permeability to sweet potatoes, can significantly shorten the cooking time, reduce nutrient loss, maximally retain the original flavor of sweet potatoes, and also significantly reduce production energy consumption.

[0028] Optionally, as Figures 3 to 5 shown in the figure, the device body is provided with support feet 10. During use, when the gas-liquid boiling and steaming device 1 is assembled, it is necessary to adjust the installation angle of the gas-liquid boiling and steaming device 1 according to the actual production in combination with the process such as the size of the sweet potato pieces. Since the gas-liquid boiling heating body of this application will generate high-frequency vibration, using a conventional rotating shaft bolt clamping component will cause the bolts to loosen, resulting in a change in the assembly angle and affecting the processing effect. Therefore, a rotatable anti-vibration fixing component is provided. In this embodiment, the lower part of the support foot 10 is provided with this rotatable anti-vibration fixing component; the rotatable anti-vibration fixing component includes a support body 11 and a rotating body 20; the lower part of the support foot 10 is connected to the rotating body 20; a card slot 21 is arranged on the upper part of the support body 11, and the rotating body 20 is rotatably connected to the card slot 21 through a rotating shaft 12; a tail part 19 is arranged at the rear side of the rotating body 20, a longitudinal screw hole is arranged at the tail part 19, a longitudinal tightening screw 18 is arranged in the longitudinal screw hole, and a transverse tightening screw 14 is arranged at its front side; a clamping table 16 is arranged at the upper rear part of the support body 11, as Figure 3As shown, in this embodiment, the clamping platform 16 is provided at the upper rear part of the clamping slot 21, and the cross-section of the clamping platform 16 is in the shape of a "7", thereby forming a step 17. The clamping platform 16 is used to limit the upper side and the front side of the longitudinal tightening screw 18. The front side of the support body 11 limits the transverse tightening screw 14. In this embodiment, the following structure is adopted: the left and right sides of the front part of the rotating body 20 are respectively provided with a left plate and a right plate 15; the left and right plates 15 are respectively provided with transverse tightening holes, and the transverse tightening holes are arranged along the front and rear directions, and the transverse tightening screw 14 passes through the transverse tightening holes to support the front side of the support body 11. The rotating body 20 is provided with a waist-shaped through hole 13 in the left and right directions, and the height of the waist-shaped through hole 13 matches the diameter of the rotating shaft 12 (playing a supporting role); the rotating body can be movably arranged on the rotating shaft through the waist-shaped through hole 13. The purpose of providing the waist-shaped through hole 13 is to enable the rotating body 20 to move along the long side of the waist-shaped through hole during the tightening operation, thereby exerting the radial tightening force of the structure on the relevant tightening bolts to achieve an anti-vibration and anti-loosening effect.

[0029] When in use, the anti-vibration loosening and clamping principle is as follows: Figure 3 As shown, the longitudinal tightening screw 18 is pressed against the step 17, at which time the longitudinal tightening screw 18 is limited in the upper position and the front position, and the two transverse tightening screws 14 are tightened on the left and right sides respectively to press against the front side of the support body 11, so that the step 17 reacts on the longitudinal tightening screw 18, thereby forming a radial clamping force between the longitudinal tightening screw 18 and the longitudinal screw hole, preventing the longitudinal tightening screw 18 from loosening relative to the longitudinal screw hole; and by tightening the longitudinal tightening screw 18, the rotating body 20 tends to rotate along the rotating shaft 12, and then the reaction force forms a radial tangential force on the transverse tightening screw 14, thereby increasing the clamping force between the transverse tightening screw 14 and the transverse tightening hole, preventing the transverse tightening screw 14 from loosening relative to the transverse tightening hole. The principle of the above structure is that: with the waist-shaped through hole 13 as the center, the longitudinal tightening screw 18 and the transverse tightening screw 14 form a radial reaction force on each other, that is, a force along the axial and radial angles of the screw hole (different from the traditional axial tightening force, for example, in the traditional tightening scheme, horizontal bolts are used to tighten the front and rear sides of the rotating body to be tightened. These two bolts realize the axial tightening force. In a high-vibration environment, the vibration is transmitted axially or radially, and the bolts are prone to loosening), thereby increasing the clamping force between them and the screw hole, thereby effectively resisting vibration, improving stability, and satisfying the continuous anti-loosening effect of tightening and fixing.

[0030] Optional, such as Figure 6As shown, it includes a steaming pot, and the gas-liquid boiling steaming device 1 is arranged inside the steaming pot. The steaming pot is a covered heating pot used to heat the water inside. To improve the degree of process mechanization, the following solution can be adopted in this embodiment: A material conveyor belt 23 is arranged inside the cavity of the steaming pot for feeding and discharging materials to and from the gas-liquid boiling steaming device. In this embodiment, at least two sets of steaming pots are provided, including a front steaming pot 28 and a rear steaming pot 28-3. A conveyor belt entrance and exit 28-1 is arranged above the liquid level of the steaming pot. The conveyor belt 23 used can be a stainless steel mesh conveyor belt. An inclined plate 28-2 is also arranged between the feed port of the steaming flow cavity 2 and the stainless steel mesh conveyor belt at this place for feeding materials into the steaming flow cavity 2. The inclination of the gas-liquid boiling steaming device 1 installed in the front steaming pot 28 can be less than 5 degrees. The purpose is that the flow speed of raw sweet potatoes is relatively fast. A lower angle can reduce the flow speed. For example, 2 degrees can be adopted. To ensure smooth material conveyance, a vibrator can be assembled on the gas-liquid boiling steaming device 1; and in some embodiments, the front steaming pot 28 can be provided with more than 2 sets. The installation angle of the rear steaming pot 28-3 can be relatively larger because after being steamed in the front steaming pot 28, the outer layer of the sweet potatoes is initially cooked through to ensure the smoothness of material flow.
