Description

Technical Field

[0001] The present invention relates to the field of food processing, in particular to the field of food sterilization, and in particular to a food high-pressure sterilizer pressurized by an air compressor. Background Art

[0002] High-pressure, high-temperature steam is one of the common sterilization methods. It is a method of sterilizing food and other objects in a high-pressure, high-temperature environment. However, in the existing technology: 1. During the sterilization process, the door of the steamer can be opened or closed, which may easily cause accidental opening of the door and cause burns to people, and the safety needs to be improved; 2. Steam is generally delivered to the steamer through a pipe. The steam is gradually distributed in the steamer by natural diffusion, and the time required is relatively long. During this period of time, since the steam is not evenly distributed, the sterilization effect on the food in the steamer is different. Feedback on the final result is that some food is easily affected by excessive high temperature and pressure, affecting the taste, and some food is not sterilized thoroughly. Based on this, the present invention proposes a food high-pressure sterilizer that uses an air compressor for pressurization. Summary of the Invention

[0003] In order to solve the problems mentioned in the above background, the present invention provides a food autoclave that utilizes air compressor to increase pressure.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0005] A food high-pressure sterilizer that uses an air compressor for pressurization includes a frame, on which a steaming cabinet component, a sealing component and a pressurizing component are installed.

[0007] Furthermore, a rotating rod is installed at the bottom of the inner cavity of the cabinet body. Several rotating rods are arranged in an array along the length of the cabinet body. The input end of the rotating rod extends to the outside of the cabinet body and is connected to the motor 3 arranged on the outer surface of the cabinet body through a synchronous belt to form a power connection;

[0008] Two sets of conveyor belts are arranged on the frame, and the two sets of conveyor belts are respectively close to the two openings of the cabinet body.

[0009] Furthermore, a lifting component is installed on the frame, and two groups of lifting components are provided and are respectively located on both sides of the cabinet body along the length direction;

[0010] The lifting component includes an upper slide rail installed on the outer surface of the cabinet body and a lower slide rail installed on the frame. The upper slide rail and the lower slide rail are parallel to the length direction of the cabinet body. Two sets of upper slide seats are slidably installed on the upper slide rail, and two sets of lower slide seats are slidably installed on the lower rail. A connecting rod is hingedly installed between the upper slide seat and the lower slide seat. There are two sets of connecting rods correspondingly provided and the two sets of connecting rods are arranged crosswise. The two sets of connecting rods are hingedly connected and the hinge is located in the middle position of the connecting rod;

[0011] The frame is provided with a linear module 1 for driving the two groups of lower slides to move closer to or away from each other.

[0012] Furthermore, the two groups of upper slides are symmetrically arranged about the vertical center line of the cabinet body, and the two groups of lower slides are symmetrically arranged about the vertical center line of the cabinet body. Racks extend from the upper slides, and the racks are parallel to the length direction of the cabinet body. A gear is meshed between the two racks.

[0013] Furthermore, the sealing component includes a movable bracket slidably installed on the frame along the length direction of the cabinet body and a linear module 2 for driving the movable bracket to move. The movable bracket is provided with a fixed seat on the side facing the cabinet body, and a sealing cover is installed on the fixed seat facing the side of the cabinet body.

[0014] Furthermore, a pressure relief pipe is extended from the bottom of the bottom cover, and a solenoid valve is provided on the pressure relief pipe. An external step is extended from the opening of the cabinet body, and a socket is provided on the external step.

[0015] The side of the fixing seat facing the cabinet body is provided with an installation groove, and a buckle assembly is provided in the installation groove. The side of the fixing seat provided with the installation groove has four sides, and the buckle assembly is provided in four groups and respectively close to the four sides.

[0016] Furthermore, the snap-on assembly includes a movable rod slidably installed in the mounting groove, the sliding direction of the movable rod is parallel to the corresponding side of the fixed seat, the movable rod is provided with two groups along its own sliding direction and a spring 2 is provided on the opposite side of the two groups of movable rods, the movable rod has an insertion rod extending vertically toward one side of the cabinet body, a protrusion extends from the free end of the insertion rod and the two protrusions are respectively located on the opposite side of the two insertion rods, and a through hole for avoiding the insertion rod is provided on the cover.

The two sloped surfaces 2 are inserted between the two movable rods of the buckle assembly. When the driving rod moves away from the button, the two movable rods are driven to move away from each other through the two sloped surfaces 2.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This solution achieves fully automated food sterilization through the coordination of conveyor belts, steam cabinet components, sealing components, and pressurization components:

[0021] 1. During the sterilization process of the steam cabinet (cabinet body plus sealing cover), the two openings of the cabinet body are sealed by the cooperation of two sets of sealing components. During this process:

[0022] 1. As steam enters, the pressure inside the steam cabinet increases, pushing the button back and triggering the snap assembly to lock the cover and cabinet body. This locking is achieved by the high pressure inside the steam cabinet. Therefore, the lock cannot be released until the pressure inside the steam cabinet returns to normal. There is no problem of accidentally opening the cabinet door, which is safer.

[0023] Furthermore, two sets of sealing members are provided to clamp the cabinet body from both ends to ensure that the cabinet body is stable and immobile, preventing the cabinet body from tilting or falling, and further improving safety. In addition, when the cabinet body undergoing sterilization falls due to various factors, the presence of the clamping assembly can support the cabinet body through the sealing member, thereby playing a role in safety and preventing it from falling.

[0024] In summary, this solution is more secure;

[0025] 2. Any component will inevitably produce wear and tear after long-term use, affecting the movement accuracy. In this solution, the cooperation between the snap assembly and the socket can not only achieve the locking between the cover and the cabinet body, but also allow errors. Specifically, during the upward movement of the cabinet body, it is only necessary to allow the insertion rod and the protrusion to pass through the socket. The subsequent protrusion can still be driven by high pressure to hook the external step set at the opening of the cabinet body to achieve the locking between the cover and the cabinet body. In other words, the upward movement of the cabinet body is allowed to have errors, as long as the error is within the preset range. This locking method can reduce the difficulty of locking between the cover and the cabinet body and extend the service life.

[0026] 2. During the process of steam injection into the steam cabinet:

[0027] Reference Figure 12The dotted line of the arc represents the deflection trajectory of the nozzle jet end, and the dotted line of the straight line represents the flow trajectory of the steam ejected from the nozzle. On the one hand, the deflection of the nozzle can change the position where the steam enters the cabinet body, so that the steam enters the cabinet body evenly. On the other hand, the deflection of the nozzle can generate wind, which blows the steam more quickly into the cabinet body. The combination of the two can increase the diffusion speed of the steam in the cabinet body, so that the steam can be evenly distributed in the cabinet body in a shorter time.

[0028] In addition, the deflection of the nozzle generates centrifugal force, which can increase the initial speed of steam entering the cabinet body. On the one hand, it can make the steam diffuse quickly in the cabinet body. On the other hand, it can increase the penetration of steam flow, so that the steam can quickly pass through the basket, so that the basket and the food inside the basket are filled with steam in a shorter time.

[0029] In summary, this solution can make the steam more quickly and evenly distributed in the steamer, so that the food is surrounded by evenly distributed steam in a short time, solving the problems in existing sterilization technology that some foods are easily affected by excessive high temperature and high pressure, affecting the taste, and some foods are not sterilized thoroughly.

DETAILED DESCRIPTION

[0044] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0045] Reference Figures 1-12 A food autoclave using air compressor boosting comprises a frame 100, on which a sterilization mechanism and a conveyor belt 101 are mounted. The conveyor belt 101 is used to pull a basket filled with food into the sterilization mechanism or to receive a basket after sterilization and pull it out. Figure 1-Figure 3 There are two groups of conveyor belts 101, one close to the two ends of the sterilization mechanism. The baskets are stacked in order on the brackets 102. The brackets 102 are moved to the conveyor belt 101 by existing technology, and then the brackets 102 and the baskets are transported to the sterilization mechanism through the conveyor belt 101. After sterilization is completed, the baskets in the sterilization mechanism are pulled to another group of conveyor belts 101 for output.

[0046] The sterilization mechanism is used to perform high-pressure and high-temperature steam sterilization on the basket. Furthermore, the sterilization mechanism includes a steam cabinet component 200, a sealing component 300 and a pressurizing component 400. The steam cabinet component 200 is used to store the basket. The sealing component 300 is provided in two groups and the two groups of sealing components 300 respectively block the two openings of the steam cabinet component 200 to form a closed environment. The pressurizing component 400 is used to pressurize the closed environment.

[0047] 1. Steaming cabinet component 200:

[0048] Reference Figure 5-Figure 7 The steaming cabinet component 200 includes a cabinet body 201 arranged horizontally. The cabinet body 201 is open at both ends along the length direction and the two sets of conveyor belts 101 are respectively close to the two openings of the cabinet body 201. The bottom of the cabinet body 201 is provided with an opening and a bottom cover 202 extends from the opening. The inner cavity width of the bottom cover 202 is consistent with the inner cavity width of the cabinet body 201, that is, the cavity wall along the width direction is located in the same plane. A pressure relief pipe is extended from the bottom of the bottom cover 202, and a solenoid valve 203 is provided on the pressure relief pipe.

[0049] A rotating shaft is installed in the bottom cover 202, and a nozzle 205 extends upward from the outer cylindrical surface of the rotating shaft. The length of the nozzle 205 is consistent with the width of the inner cavity of the cabinet body 201, that is, the two side surfaces of the nozzle 205 along the length direction are respectively located in the same plane as the two cavity walls of the cabinet body 201 along the width direction. In addition, the input end of the rotating shaft extends to the outside of the cabinet body 201 and is connected to the power of the motor 206 provided on the cabinet body 201. The nozzle 205 is connected to the steam supply source through the steam pipe 204. The steam supply source can be an existing technology such as a steam generator; its significance is that steam enters the cabinet body 201 through the steam pipe 204 and the nozzle 205. At the same time, the motor 206 drives the rotating shaft to rotate, thereby causing the nozzle 205 to swing. In this way, referring to Figure 12 The dotted line of the arc represents the deflection trajectory of the jet end of the nozzle 205, and the dotted line of the straight line represents the flow trajectory of the steam ejected by the nozzle 205. The deflection of the nozzle 205 can, on the one hand, change the position where the steam enters the cabinet body 201, so that the steam enters the cabinet body 201 evenly. On the other hand, the deflection of the nozzle 205 can generate wind, and the steam diffuses more quickly in the cabinet body 201 through the wind. The combination of the two can increase the diffusion speed of the steam in the cabinet body 201, so that the steam can be evenly distributed in the cabinet body 201 in a shorter time. In addition, the deflection of the nozzle 205 generates centrifugal force, which can increase the initial speed of the steam entering the cabinet body 201, on the one hand, making the steam diffuse quickly in the cabinet body 201, and on the other hand, it can increase the penetration of the steam flow, so that the steam can quickly pass through the basket, so that the basket and the food in the basket are filled with steam in a shorter time. All of these can increase the steam sterilization effect and efficiency of food.

[0050] Reference Figure 5 and Figure 6 A rotating rod 207 is installed at the bottom of the inner cavity of the cabinet body 201. The rotating rod 207 is parallel to the width direction of the cabinet body 201. Several rotating rods 207 are arranged in an array along the length direction of the cabinet body 201. The input end of the rotating rod 207 extends to the outside of the cabinet body 201 and is powered by a synchronous belt 208 with a motor 3 arranged on the outer surface of the cabinet body 201; the conveyor belt 101 pulls the bracket 102 to move, so that one end of the bracket 102 is supported by the rotating rod 207, and then, the motor 3 drives the rotating rod 207 to rotate, and cooperates with the conveyor belt 101 to transfer the bracket 102 into the cabinet body 201. Similarly, after sterilization is completed, the motor 3 drives the rotating rod 207 to rotate, so that one end of the bracket 102 is supported by another set of conveyor belts 101, and the rotating rod 207 cooperates with the conveyor belt 101 to transfer the bracket 102 to the conveyor belt 101.

[0051] Reference Figure 5 and Figure 6 The frame 100 is equipped with a lifting component for driving the cabinet body 201 to move in the vertical direction. The lifting component is provided with two groups and is respectively located on both sides of the cabinet body 201 along the length direction. Furthermore, the lifting component includes an upper slide rail installed on the outer surface of the cabinet body 201 and a lower slide rail installed on the frame 100. The upper and lower slide rails are parallel to the length direction of the cabinet body 201. Two groups of upper slides 210 are slidably installed on the upper slide rail, and two groups of lower slides 209 are slidably installed on the lower rail. The two groups of upper slides 210 are symmetrically arranged about the vertical center line of the cabinet body 201, and the two groups of lower slides 209 are also symmetrically arranged about the vertical center line of the cabinet body 201.

[0052] A connecting rod 211 is hingedly installed between the upper slide 210 and the lower slide 209. There are two groups of connecting rods 211 and the two groups of connecting rods 211 are arranged crosswise. The two groups of connecting rods 211 are also hingedly connected and the hinge is located at the middle position of the connecting rod 211. The hinge axes formed by these hinges are parallel to the width direction of the cabinet body 201. When the two groups of lower slides 209 move closer to or away from each other, the cabinet body 201 will move up or down.

[0053] Preferably, a linear module 212 is provided on the frame 100 for driving the two groups of lower slides 209 to move closer to or away from each other. The linear module 212 includes a screw rod, which is divided into two threaded segments with opposite spiral directions along the axis. The two threaded segments are respectively connected to the two groups of lower slides 209. The screw rod is driven by motor 4 to rotate, thereby causing the two groups of lower slides 209 to move closer to or away from each other.

[0054] Preferably, a gear rack set 213 is provided between the two sets of upper slides 210, and the gear rack set 213 includes a rack connected to the upper slide 210, and the rack is parallel to the length direction of the cabinet body 201, and a gear is provided between the two racks. In this way, when the cabinet body 201 is driven to move by the lifting component, the two upper slides 210 maintain a symmetrical arrangement, so that the forces on both sides of the cabinet body 201 are balanced, and the cabinet body 201 remains in a horizontal state. On the contrary, if there is no gear rack set 213, then after long-term use, although the cabinet body 201 can be driven to move, the symmetrical arrangement between the two upper slides 210 will inevitably be affected, resulting in unbalanced forces on both sides of the cabinet body 201, and then causing the cabinet body 201 to tilt slightly to one side. The tilting will affect the subsequent sealing of the cabinet body 201 opening, and in addition, it is high-pressure and high-temperature steam sterilization, which will affect the sealing, easily leading to incomplete sterilization, and easily leading to steam leakage and scalding surrounding staff.

[0055] 2. Sealing member 300:

[0056] Reference Figure 6 An external step extends from the opening of the cabinet body 201, and a socket 2011 is provided on the external step.

[0057] Reference Figure 1 When the basket is transported toward the cabinet body 201 , the sealing member 300 is located above the cabinet body 201 .

[0058] Reference Figure 8 and Figure 9 The sealing component 300 includes a movable bracket 301 slidably mounted on the frame 100 along the length direction of the cabinet body 201 and a linear module 2 302 for driving the movable bracket 301 to move. The linear module 2 302 can be an electric telescopic rod technology or a screw linear technology, which will not be described in detail.

[0059] A fixing seat 303 is provided on one side of the movable bracket 301 facing the cabinet body 201 . The thickness direction of the fixing seat 303 is parallel to the length direction of the cabinet body 201 . A cover 304 is installed on the side of the fixing seat 303 facing the cabinet body 201 .

[0060] The fixing seat 303 is provided with an installation groove on the side facing the cabinet body 201, and a snap assembly is provided in the installation groove. Furthermore, in this solution, the cabinet body 201 is rectangular in shape, and the fixing seat 303 and the cover 304 are also rectangular plate-shaped. The side of the fixing seat 303 with the installation groove has four sides, and the snap assembly is provided with four groups and close to these four sides respectively. Furthermore, the snap assembly includes a movable rod 308 slidably installed in the installation groove, and the sliding direction of the movable rod 308 is parallel to the corresponding side of the fixing seat 303. The movable rod 308 is provided with two groups along its own sliding direction and a spring 2 309 is provided on the opposite side of the two groups of movable rods 308. The movable rod 308 has an insertion rod 310 extending vertically toward the side of the cabinet body 201, and a protrusion 311 extends from the free end of the insertion rod 310 and the two protrusions 311 are respectively located on the opposite side of the two insertion rods 310. The cover 304 is provided with a through hole for avoiding the insertion rod 310.

[0061] A button 305 and a spring 306 located between the bottom of the groove and the button 305 are slidably installed in the installation groove, and the free end of the button 305 passes through the avoidance hole set on the cover 304.

[0062] A driving rod 307 is arranged between the buckle assembly and the button 305. The sliding direction of the driving rod 307 is perpendicular to the sliding direction of the movable rod 308. One end of the driving rod 307 is provided with a slope 1 and the other end is provided with two slopes 2. The button 305 contacts the slope 1 and when the button 305 is close to the bottom of the installation groove, the driving rod 307 is driven to move away from the button 305 through the slope 1. The two slopes 2 are inserted between the two movable rods 308 of the buckle assembly. When the driving rod 307 moves away from the button 305, the two movable rods 308 are driven to move away from each other through the two slopes 2, and the spring 2 309 is compressed.

[0063] The process of sealing the opening of the cabinet body 201 by the sealing member 300:

[0064] When the basket containing food is placed into the cabinet body 201, the lifting component drives the cabinet body 201 to move up to a preset height, so that the center line of the cabinet body 201 parallel to the length direction coincides with the center line of the cover 304 parallel to the thickness direction. Then, the second linear module 302 drives the movable bracket 301 to move, so that the cover 304 blocks the opening of the cabinet body 201. During this process, the insertion rod 310 passes through the insertion hole 2011.

[0065] Then, as steam is injected into the cabinet body 201, the air pressure in the cabinet body 201 increases, which pushes the button 305 to move. The button 305 pushes the two movable rods 308 in the buckle assembly to move via the driving rod 307. The movable rod 308 moves together with the insertion rod 310 and the protrusion 311, and eventually the protrusion 311 hooks the external step set at the opening of the cabinet body 201. At this time, the cover 304 and the cabinet body 201 are snap-fitted. The snap-fitting is achieved by the high pressure in the cabinet body 201. Therefore, the snap-fitting cannot be released until the air pressure in the cabinet body 201 returns to normal pressure, which increases safety.

[0066] After the sterilization is completed, the solenoid valve 203 is opened, the air pressure in the cabinet body 201 is restored, the clamping is cancelled, and the second linear module 302 drives the cover 304 away from the cabinet body 201, so that the opening of the cabinet body 201 is opened.

[0067] In the above process, the reason why the card block assembly and the socket 2011 are connected is that as the air pressure in the cabinet body 201 increases, the cover 304 will be pushed back. If there is no connection, the pressure will be all on the threaded connection between the movable bracket 301 and the screw rod, which can easily cause damage to the threads at the threaded connection.

[0068] In the above process, the cooperation between the snap assembly and the socket 2011 can not only realize the locking between the cover 304 and the cabinet body 201, but also allow errors. Specifically, during the upward movement of the cabinet body 201, it is only necessary to allow the insertion rod 310 and the protrusion 311 to pass through the socket 2011. The subsequent protrusion 311 can still hook the external step set at the opening of the cabinet body 201 under high pressure to achieve the locking between the cover 304 and the cabinet body 201. In other words, the upward movement of the cabinet body 201 allows errors, as long as the errors are within a preset range. Its significance lies in that after long-term use, each component will inevitably produce wear and tear, affecting the movement accuracy. In this solution, this locking method can reduce the difficulty of locking between the cover 304 and the cabinet body 201 and extend the service life.

[0069] In the above process, since there are two groups of sealing components 300, in addition to the sealing function, the cabinet body 201 can also be clamped from both ends to ensure that it is stable and motionless. In addition, when the cabinet body 201 undergoing sterilization falls due to various factors, due to the presence of the snap-fit assembly, the cabinet body 201 can be supported by the sealing component 300, thereby playing a role in safety and preventing it from falling.

[0070] 3. Pressurized component 400:

[0071] Reference Figure 10 and Figure 11The boost component 400 includes a ring-shaped gas tank 403 and a core tube 405 coaxially located in the gas tank 403 and capable of rotating. The outer circumferential surface of the core tube 405 is evenly spaced with a number of combustion holes, which is equivalent to a stove head. The bottom of the core tube 405 is provided with a connecting tube three 406 through a rotary joint. The end of the connecting tube three 406 is connected to the gas source, and the core tube 405 is driven to rotate by the motor two 408.

[0072] The air inlet of gas tank 403 is provided with connecting pipe 2 404, and the air outlet is provided with connecting pipe 1 401. The end of connecting pipe 2 404 is connected to the air compressor, and the end of connecting pipe 1 401 is connected to bottom cover 202. A three-way valve 402 is installed at the connection point. Three-way valve 402 has two air outlets and one air inlet. The air inlet is connected to connecting pipe 1 401, one air outlet is connected to bottom cover 202, and the other air outlet is connected to the outside world. A temperature sensor is installed in three-way valve 402.

[0073] The air compressor starts and sends air into the gas tank 403. At the same time, the fuel gas enters the core tube 405 and is ignited by the igniter 407. The flame heats the gas tank 403. The motor 2 408 drives the core tube 405 to rotate to make the heating more uniform. The heated air will initially push the air in the connecting pipe 1 401, so that the air in the connecting pipe 1 401 is discharged to the outside through the three-way valve 402. When the temperature sensor detects that the air temperature reaches the preset value, the three-way valve 402 switches the state, and the hot air enters the cabinet body 201 through the three-way valve 402, and the cabinet body 201 is pressurized. Since the air is heated, the air injected into the cabinet body 201 due to the pressurization will not affect the temperature of the cabinet body 201.

[0074] The workflow of the present invention is:

[0075] The cabinet body 201 moves downward so that the opening faces the conveyor belt 101. Then, the conveyor belt 101 cooperates with the rotating roller 207 to move the bracket 102 and the basket containing the food into the cabinet body 201. Then, the cabinet body 201 moves upward, and the opening of the cabinet body 201 is sealed by the sealing member 300.

[0076] Then, steam enters the cabinet body 201 through the nozzle 205, and the air pressure of the cabinet body 201 increases, so that the snap assembly is connected, and the seal between the cover 304 and the cabinet body 201 is locked. At the same time, hot air is injected into the cabinet body 201 through the pressurizing component 400 to achieve the purpose of pressurization, and finally the cabinet body 201 is in a high-temperature and high-pressure steam state to sterilize the food. After the sterilization is completed, the solenoid valve 203 is opened, and the cabinet body 201 is depressurized. Then, the cabinet body 201 moves down, and the basket is moved to another set of conveyor belts 101 by the rotating rod 207. At this point, the sterilization of one batch of food is completed, and the next batch of food is moved to the cabinet body 201. The above process is repeated to sterilize the next batch of food.

[0077] The above-mentioned movement of the cabinet body 201, transfer of the basket, sealing of the cabinet body 201 opening, high-pressure triggering of the snap assembly to achieve snap connection, steam injection and pressurization process have been described above and will not be repeated here.
