Description

Technical Field

[0001] The invention belongs to the technical field of fermented bean curd making, in particular to a fermented bean curd making sterilizing device. Background Art

[0002] Stuffed tofu is usually made with tofu as the main ingredient, and may be sandwiched with meat, vegetable or other fillings. During the production process, stuffed tofu will come into contact with various microorganisms, such as bacteria, mold and yeast. These microorganisms may come from the raw materials themselves, the production environment or manual operations in the production process. Therefore, stuffed tofu needs to be sterilized to ensure the safety of the product and extend the shelf life.

[0003] When the existing sterilization device for making stuffed tofu is used, the container containing the stuffed tofu is generally placed in the interior of a sterilization box, and then a low-temperature environment is created to inhibit the growth and reproduction of microorganisms, thereby achieving the effect of sterilizing the stuffed tofu. However, in order to reduce the difficulty of design and the manufacturing cost, most of the existing sterilization devices have basically fixed internal storage racks. Since the position of the liquid nitrogen inlet in the sterilization box is also fixed, the contact area and contact time between the stuffed tofu and the surrounding cold air are relatively fixed. This will cause some stuffed tofu on the storage rack to have a small contact area or a short contact time with the cold air, thereby failing to fully perform heat exchange, resulting in the internal microorganisms not being completely frozen to death. Therefore, a sterilization device for making stuffed tofu is proposed to solve the problems raised in the background technology. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides a tofu stuffed fermented bean curd making and sterilizing device, comprising a sterilizing chamber 1, and further comprising:

[0036] A moving component 2, the moving component 2 is movably connected to the inside of the sterilization chamber 1, and a pull rod 5 is fixedly connected to one side of the bottom of the moving component 2;

[0037] A rotating assembly 3, the rotating assembly 3 is movably connected to the moving assembly 2, and the interior of the rotating assembly 3 is movably connected to a clamping assembly 4;

[0038] A limit assembly 6, the limit assembly 6 is movably connected to the inside of the pull rod 5;

[0039] The moving assembly 2 includes a support plate 21, and a circular groove 22 is formed on one side of the support plate 21;

[0040] The rotating assembly 3 includes a motor 31 fixedly connected to the inside of the support plate 21, the output shaft end of the motor 31 is fixedly connected to a turntable 32, the outer wall of the turntable 32 is annularly fixedly connected to a first connecting rod 33 at an equal angle, the top end of the first connecting rod 33 is hinged to a second connecting rod 34, the end of the second connecting rod 34 away from the first connecting rod 33 is hinged to a slider 35, and the end of the second connecting rod 34 close to the first connecting rod 33 is fixedly connected to a placement plate 36;

[0041] The limiting assembly 6 includes a limiting plate 61, and second inclined grooves 62 are provided at both ends of the limiting plate 61 close to the support plate 21. The bottom end of the inner cavity of the support plate 21 is symmetrically and movably connected with two push blocks 64, and the interior of the sterilization chamber 1 is movably connected with two inclined blocks 66 that cooperate with the push blocks 64.

[0042] The above scheme is adopted: by setting a clamping assembly 4, it is convenient to fix the container containing stuffed tofu on the placement plate 36, and the sliding trajectory of the slider 35 is limited by the circular groove 22. Since the turntable 32 is located at the eccentric part of the rotation axis of the circular groove 22, when the first connecting rod 33 rotates to a different position, the second connecting rod 34 will drive the placement plate 36 to rotate, thereby correcting the position of the placement plate 36, thereby ensuring that the placement plate 36 and the container on which the stuffed tofu is placed always maintain a horizontal position. Subsequently, the turntable 32 is driven by the motor 31 to rotate continuously, so that the stuffed tofu in the containers of different placement plates 36 can be evenly exposed to the liquid nitrogen gas, thereby improving the uniformity and efficiency of sterilization.

[0043] like Figure 2 , Figure 5 and Figure 6 As shown, rollers 23 are provided at the upper and lower ends of the support plate 21, and a sliding groove matching the roller 23 is opened on the inner wall of the sterilization chamber 1. The turntable 32 is located at the eccentric part of the rotating axis of the circular groove 22. The turntable 32 is movably connected to the support plate 21, and the slider 35 is movably connected to the inside of the circular groove 22. The hinge axis of the second connecting rod 34 close to one end of the first connecting rod 33 passes through the outer wall of the first connecting rod 33 and the placement plate 36. A third connecting rod 37 is provided between two adjacent placement plates 36, and the two ends of the third connecting rod 37 are respectively hinged to the two placement plates 36.

[0044] Adopting the above scheme: through the setting of the third connecting rod 37, its function is as follows: Figure 5 As shown, when the first connecting rod 33 drives the second connecting rod 34 and the placement plate 36 at one end thereof to rotate, the design of the third connecting rod 37 can provide certain support and limitation between every two adjacent placement plates 36, thereby improving the stability of the placement plates 36 during rotation, and further improving the reliability of the overall operation of the device.

[0045] like Figure 3 , Figure 5 and Figure 7As shown, the clamping assembly 4 includes two clamping plates 41 which are symmetrically arranged inside the placement plate 36, and the first spring plates 42 are fixedly connected to the opposite sides of the two clamping plates 41. The clamping plates 41 are elastically connected to the placement plate 36 through the first spring plates 42. The bottom of the inner cavity of the placement plate 36 is movably connected with a pressure plate 43, and the pressure plate 43 passes through the outer wall of the placement plate 36 and extends to the outside of the placement plate 36. Both ends of the top of the pressure plate 43 are provided with first inclined grooves 44, and the two first inclined grooves 44 are in opposite directions. The top of the clamping plate 41 is in the shape of an inclined surface, and the bottom end of the clamping plate 41 is provided with a connecting column that is movably clamped inside the first inclined groove 44, and the inner wall of the placement plate 36 is provided with a square groove for limiting the clamping plate 41 in the horizontal direction.

[0046] The above scheme is adopted: through the design of the pressing plate 43, its function is that when the sterilized stuffed tofu container needs to be taken out from the placement plate 36, at this time, the operator presses the pressing plate 43 upwards, thereby driving the connecting column at the bottom of the clamping plate 41 to slide along the trajectory of the first inclined groove 44. Since the inner wall of the placement plate 36 is provided with a square groove for limiting the clamping plate 41 in the horizontal direction, the connecting column can only drive the clamping plate 41 to move in the direction away from the first spring piece 42. When the pressing plate 43 is pressed to the predetermined position, at this time, the two clamping plates 41 are released from the abutment with the outer wall of the stuffed tofu container, thereby facilitating the removal of the container from the placement plate 36.

[0047] like Figure 8 As shown, a second spring piece 63 is fixedly connected to the side of the limit plate 61 away from the second inclined groove 62, and the limit plate 61 is elastically connected to the pull rod 5 through the second spring piece 63. The two second spring pieces 63 are in opposite directions. The bottom ends of both sides of the support plate 21 are provided with a slot adapted to the inclined block 66. The inclined block 66 is located inside the slot in the initial state. The opposite sides of the two inclined blocks 66 are fixedly connected with a third spring piece 67, and the inclined block 66 is elastically connected to the sterilization chamber 1 through the third spring piece 67. The opposite ends of the two push blocks 64 are fixedly connected with a round rod 65, and the round rod 65 is movably clamped in the inside of the limit plate 61. The inner wall of the support plate 21 is provided with a limit groove matching the push block 64.

[0048] The above scheme is adopted: through the design of the inclined block 66 and the third spring piece 67, its function is that when the support plate 21 moves to the inside of the sterilization chamber 1, the side wall of the support plate 21 will abut against the inclined surfaces of the two inclined blocks 66, thereby squeezing the two inclined blocks 66 to move in opposite directions, and when one side of the support plate 21 is in contact with the inner wall of the sterilization chamber 1, at this time, the slots opened on both sides of the support plate 21 are in contact with the inclined block 66, and then the inclined block 66 is reset under the action of the elastic force of the third spring piece 67, and then snapped into the inside of the slot of the support plate 21, thereby limiting the position of the support plate 21, thereby preventing the sterilization chamber 1 from moving inside the sterilization chamber 1 due to vibration or rotation of the turntable 32 during operation, thereby affecting the normal operation of the device.

[0049] like Figure 1 and Figure 2 As shown, an air inlet pipe 7 connected to the liquid nitrogen storage tank is arranged at the top of the sterilization chamber 1, a temperature sensor 8 is fixedly connected to the top of the inner cavity of the sterilization chamber 1, and a condensate recovery component 9 is arranged at the bottom of the inner cavity of the sterilization chamber 1.

[0050] The above scheme is adopted: through the design of the condensed water recovery component 9, its function is that during the sterilization process, the liquid nitrogen gas will condense into water droplets on the low-temperature surface in the sterilization chamber 1 such as the box wall. Therefore, through the design of the condensed water recovery component 9, these condensed waters are collected, and by providing a drainage pipe, the collected condensed water is discharged from the sterilization chamber 1.

[0051] The working principle and use process of the present invention are as follows: the operator puts the stuffed bean curd into a specific square container, and then puts the square container on top of the placement plate 36. When the container is put in, its outer wall will abut against the inclined surface of the top of the two clamping plates 41, thereby squeezing the two clamping plates 41 to move in opposite directions and stretching the first elastic sheet 42. When the bottom of the container fits with the top of the placement plate 36, the clamping plate 41 fits with the outer wall of the container under the action of the pulling force of the first elastic sheet 42, so that the two clamping plates 41 respectively abut against the two sides of the outer wall of the container, thereby effectively clamping the square container containing the stuffed bean curd;

[0052] When several containers are placed on the placement plate 36 and are limited by the clamping assembly 4, the operator holds the pull rod 5 and pushes the support plate 21 toward the inside of the sterilization chamber 1 through the pull rod 5. When the support plate 21 moves, it also drives the rotating assembly 3 and the clamping assembly 4 thereon to move as a whole, thereby moving the container with the stuffed tofu into the inside of the sterilization chamber 1. When the side wall of the support plate 21 abuts against the inner wall of the sterilization chamber 1, the door panel 10 is closed to seal the sterilization chamber 1.

[0053] Subsequently, the operator starts the liquid nitrogen storage tank and delivers the liquid nitrogen gas to the interior of the sterilization chamber 1 through the air inlet pipe 7. At the same time, the electric fan inside the sterilization chamber 1 is started to improve the circulation of the liquid nitrogen gas inside the sterilization chamber 1. When the liquid nitrogen gas fills the interior of the sterilization chamber 1, a low-temperature environment is formed inside the sterilization chamber 1. Subsequently, the motor 31 is started to drive the turntable 32 and several first connecting rods 33 on its outer wall to rotate together, and then the second connecting rod 34 is driven to rotate in the same direction through the first connecting rod 33. When the second connecting rod 34 rotates, it drives the slider 35 to slide along the trajectory of the circular groove 22, and the Since the turntable 32 is located at the eccentric position of the rotating shaft of the circular groove 22, and the circular groove 22 limits the movement trajectory of the slider 35, when the first connecting rod 33 drives the second connecting rod 34 to rotate to different positions, the second connecting rod 34 will drive the placement plate 36 fixedly connected at one end thereof to rotate, thereby correcting the position of the placement plate 36, thereby ensuring that the placement plate 36 and the container on which the stuffed tofu is placed always maintain a horizontal position. Finally, the motor 31 drives the continuous rotation of the turntable 32, so that the stuffed tofu in the containers of different placement plates 36 can be evenly exposed to the liquid nitrogen gas, thereby improving the uniformity and efficiency of sterilization.

[0054] When the sterilization is completed, the temperature sensor 8 will monitor the temperature in the sterilization chamber 1 in real time, convert the monitored information into an electrical signal, and transmit the signal to the information terminal, so as to remind the operator to take out the stuffed tofu in time;

[0055] When the operator needs to take it out, he opens the door panel 10 and then presses the limit plate 61 in a straight line in the direction away from the support plate 21. When the limit plate 61 moves, the round rod 65 slides along the track of the second inclined groove 62. Since the inner wall of the support plate 21 is provided with a limit groove for limiting the push block 64 in the horizontal direction, and since the two second inclined grooves 62 face opposite directions, the round rod 65 can only move along the track of the second inclined groove 62 to drive the push block 64 to move in the direction of the inclined block 66, thereby pressing the inclined block 66. The operator squeezes the inclined block 66 to shrink into the interior of the sterilization chamber 1, thereby releasing the inclined block 66 from the clamping connection with the support plate 21. Finally, the operator presses the limit plate 61 while pulling the pull rod 5 toward the outside of the sterilization chamber 1, thereby driving the support plate 21 to move to the outside of the sterilization chamber 1 through the pull rod 5, thereby facilitating the timely removal of the stuffed tofu on the placement plate 36 from the interior of the sterilization chamber 1, thereby avoiding the stuffed tofu from being placed in the sterilization chamber 1 for too long, thereby avoiding the phenomenon of excessive freezing of the stuffed tofu.
