Description

Technical Field

[0001] This utility model is an apple chip differential pressure puffing device, belonging to the field of differential pressure puffing equipment. Background Technology

[0002] Variable temperature pressure difference puffing drying technology is a new, environmentally friendly, and energy-saving non-fried puffing drying technology. Its production line equipment mainly consists of a puffing tank and a vacuum tank 5-10 times larger in volume. Fruits and vegetables are placed inside the puffing tank, and an air compressor pressurizes the tank. Heating causes the internal moisture of the fruits and vegetables to continuously vaporize and evaporate. As the pressure inside the tank rises from atmospheric pressure to a certain level, the material also heats up to a certain temperature, placing the product in a high-temperature heated state. Then, the pressure relief valve connecting the puffing tank and the vacuum tank (which has been pre-evacuated) is quickly opened. Due to the instantaneous pressure drop inside the puffing tank, the internal moisture evaporates instantly, causing the fruit and vegetable tissue to rapidly expand and form a uniform honeycomb structure. Heating and dehydration are maintained under vacuum for a period of time until the required safe moisture content (3%-5%) is reached. Drying is then stopped, and the vacuum is released when the puffing tank cools to room temperature. The product is then removed, yielding puffed fruit and vegetable products.

[0003] Existing differential pressure puffing devices require a long cooling time after puffing before manual removal, which greatly reduces production efficiency. Furthermore, the material can only be removed after the temperature inside the puffing tank returns to room temperature, and it needs to be reheated for the next processing, resulting in significant heat loss. Therefore, it is necessary to design a differential pressure puffing device for apple chips. Utility Model Content

[0006] Furthermore, a geared motor is installed on the side of the side plate away from the puffing tank, and the output end of the geared motor is connected to the rotating frame through a pulley mechanism. The pulley mechanism includes two pulleys, one large and one small, and a belt for connecting the two pulleys. The output end of the geared motor is connected to the small pulley through a rotating shaft, and the large pulley is connected to the center of the rotating frame through a rotating shaft.

[0007] Furthermore, a sealing ring is uniformly bonded to the inner wall of the sealing cap, and the inner diameter of the sealing cap matches the outer diameter of the opening of the puffing tank.

[0008] Furthermore, the apple slice support assembly includes a mounting frame, a connector, and a tray. The mounting frame is designed in the shape of a "Γ". The connectors are hinged to both sides of the bottom of the mounting frame crossbar, and the trays are evenly inserted between the connectors.

[0009] A first control valve is provided on the top of the expansion tank near the air compressor, and the output end of the air compressor is connected to the first control valve through a telescopic pipe. A pressure relief valve is provided at the center of the expansion tank near the vacuum chamber, and a safety valve is provided on the expansion tank above the pressure relief valve. The output ends of both the safety valve and the pressure relief valve are connected to the vacuum chamber through telescopic pipes.

[0010] A drain port is provided at the bottom of one end of the vacuum chamber, and a second three-way valve is provided at the top of the vacuum chamber on the side away from the expansion tank. One outlet of the second three-way valve is connected to the input end of the air compressor through a conduit, and the other outlet of the second three-way valve is connected to the external environment. A first three-way valve is provided at the center of the side of the vacuum chamber near the expansion tank, and a vacuum pump is installed below the first three-way valve. The exhaust end of the vacuum pump is connected to the vacuum chamber, and the inlet end of the vacuum pump is connected to the first three-way valve. The pressure relief valve is connected to the first three-way valve through a telescopic pipe.

[0011] The mounting plate is connected to the sealing cover by bolts, and a rotary motor is embedded in the center of the mounting plate. A connecting plate is rotatably mounted in the center of the sealing cover, and the output end of the rotary motor is connected to the connecting plate through a rotating shaft. The connecting plate is connected to the mounting bracket by bolts.

[0012] A connecting plate is provided at the center of the vertical plate of the mounting bracket, and the connecting plate is connected to the connecting plate by bolts.

[0013] The beneficial effects of this utility model are:

[0014] 1. The system is equipped with four sealing caps connected to a rotating frame, allowing for intermittent 90° rotation. Apple slice carrier components are installed inside the sealing caps. During each processing run, the apple slices are loaded onto one of the carrier components, then rotated 90° to align with the puffing tank. The puffing tank moves on an electric slide rail, docking with the sealing cap for pressurization and heating. The hot air is then drawn into a vacuum chamber, achieving differential pressure puffing. The rotating frame then rotates, and the slices cool automatically at the next two stations, eliminating the need to wait for the apple slices to cool before unloading, thus improving work efficiency. Simultaneously, the puffing tank maintains a certain temperature, allowing for faster heating and reduced heat loss when processing the next batch of apple slices.

[0015] 2. The device uses baffles inside the vacuum chamber to allow compressed air containing steam to enter the chamber and come into contact with the baffles, resulting in heat exchange. The steam in the air condenses into water droplets, which fall down the baffles and are discharged through the drain port. This avoids direct steam discharge from affecting electrical components in the workshop. Furthermore, the hot air, after removing the water vapor, can be reused in the air compressor under the control of the second and third-way valves, further reducing heat loss.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an apple chip differential pressure puffing device, including a base 1, a side plate 2 on one side of the base 1, and a rotating frame 4 rotatably connected to the center of the side plate 2. An installation plate 13 is integrally connected to the outer periphery of the rotating frame 4, and a sealing cover 3 is fixed to the side of the installation plate 13 away from the side plate 2. An apple chip carrying assembly 5 is rotatably connected to the side of the sealing cover 3 away from the side plate 2. Electric slide rails 15 are provided at both ends of the top of the base 1, and a vacuum box 12 is fixed to the other side of the top of the base 1. A puffing tank 6 is installed on the base 1 between the vacuum box 12 and the sealing cover 3 via an installation hoop 7. Electric sliders 701, adapted to the electric slide rails 15, are provided at both ends of the bottom of the installation hoop 7. The electric sliders 701 move within the electric slide rails 15, which can drive the installation hoop 7 to move, allowing the puffing tank 6 to move back and forth, docking or separating from the sealing cover 3, realizing puffing processing or material replacement. The design is more reasonable.

[0025] For example, baffles 17 are arranged vertically inside the vacuum chamber 12, and heat-conducting plates 28 are installed at both ends of the baffles 17. An air compressor 11 is installed at the top of the vacuum chamber 12. After the compressed air containing steam enters the vacuum chamber 12, it comes into contact with the baffles 17 and heat exchange occurs. The steam in the air condenses into water droplets, which fall down along the baffles 17 and are discharged from the drain port 18, thus avoiding the direct discharge of steam from affecting the electrical components in the workshop.

[0026] For example, a geared motor 24 is installed on the side of the side plate 2 away from the puffing tank 6, and the output end of the geared motor 24 is connected to the rotating frame 4 through a pulley mechanism 25. The pulley mechanism 25 includes two pulleys, one large and one small, and a belt for connecting the two pulleys. The output end of the geared motor 24 is connected to the small pulley through a rotating shaft, and the large pulley is connected to the center of the rotating frame 4 through a rotating shaft. When the geared motor 24 works, it drives the small pulley to rotate, and through the belt drive, it drives the large pulley to rotate, thus causing the rotating frame 4 to rotate. The circumference of the small pulley is one-quarter of the circumference of the large pulley. That is, for every rotation of the geared motor 24, the rotating frame 4 rotates 90°, which makes it easy to control the rotation angle.

[0027] Please see Figure 3 The inner wall of the sealing cap 3 is uniformly bonded with a sealing ring 301, and the inner diameter of the sealing cap 3 matches the outer diameter of the opening of the puffing tank 6. The matching design makes the connection between the sealing cap 3 and the puffing tank 6 tighter, and the design of the sealing ring 301 makes the sealing at the connection better.

[0028] Please see Figure 4 The apple slice support component 5 includes a mounting frame 21, a connector 23, and a tray 22. The mounting frame 21 is designed in the shape of a "Γ". The connectors 23 are hinged to both sides of the bottom of the crossbar of the mounting frame 21, and the trays 22 are evenly inserted between the connectors 23. The hinged design between the connectors 23 and the mounting frame 21 allows the connectors 23 to rotate relative to the mounting frame 21. When the control of the rotation motor 14 is not precise enough and the angle of the mounting frame 21 is skewed, the connectors 23 can remain vertical under the action of gravity, preventing the apple slices from falling. The design is more reasonable.

[0029] Please see Figure 1 A first control valve 8 is provided on the top of the expansion tank 6 near the air compressor 11, and the output end of the air compressor 11 is connected to the first control valve 8 through a telescopic tube. A pressure relief valve 10 is provided at the center of the expansion tank 6 near the vacuum box 12, and a safety valve 9 is provided on the expansion tank 6 above the pressure relief valve 10. The output ends of both the safety valve 9 and the pressure relief valve 10 are connected to the vacuum box 12 through telescopic tubes. When the gas pressure inside the expansion tank 6 is too high, some gas can be discharged through the safety valve 9 and enter the vacuum box 12 to avoid direct discharge and burns to surrounding personnel.

[0030] Please see Figure 1 and Figure 5A drain port 18 is provided at the bottom of one end of the vacuum chamber 12, and a second three-way valve 27 is provided at the top of the side of the vacuum chamber 12 away from the expansion tank 6. One outlet of the second three-way valve 27 is connected to the input end of the air compressor 11 through a conduit, and the other outlet of the second three-way valve 27 is connected to the external environment. A first three-way valve 26 is provided at the center of the side of the vacuum chamber 12 near the expansion tank 6, and a vacuum pump 16 is installed below the first three-way valve 26. The exhaust end of the vacuum pump 16 is connected to the vacuum chamber 12, and the inlet end of the vacuum pump 16 is connected to the first three-way valve 26. A pressure relief valve 10 is connected to the first three-way valve 26 through a telescopic pipe. During processing, the expansion tank... After the pressure is increased for a period of time in step 6, the pressure relief valve 10 opens, and the high-pressure gas instantly enters the vacuum chamber 12 through the first three-way valve 26 to complete the pressure relief. This causes the moisture inside the apple slices to suddenly vaporize and flash, generating a strong vapor pressure difference, which causes the apple slice cells and tissues to expand and achieve the purpose of puffing, thus completing the processing of apple chips. Then, the vacuum pump 16 works to draw the gas in the puffing tank 6 into the vacuum chamber 12. The apple slices are dehydrated and dried under vacuum. After the compressed gas containing steam comes into contact with the baffle plate 17, the steam condenses. During the next processing, the remaining hot air can be guided to the air compressor 11 through the second three-way valve 27 for secondary use, further reducing heat loss.

[0031] Please see Figure 2 and Figure 3 The mounting plate 13 is connected to the sealing cover 3 by bolts, and a rotary motor 14 is embedded in the center of the mounting plate 13. A connecting plate 20 is rotatably mounted in the center of the sealing cover 3, and the output end of the rotary motor 14 is connected to the connecting plate 20 through a rotating shaft. The connecting plate 20 is connected to the mounting bracket 21 by bolts. When the rotary motor 14 works, it can drive the connecting plate 20 to rotate, thereby causing the mounting bracket 21 to rotate. This ensures that the vertical rod of the mounting bracket 21 is in a vertical state, preventing the apple slice bearing component 5 from tilting when it moves with the sealing cover 3, which would cause the apple slice to fall off. The design is more reasonable.

[0032] Please see Figure 4 A connecting plate 2101 is provided at the center of the vertical plate of the mounting bracket 21, and the connecting plate 2101 is connected to the connecting plate 20 by bolts. Anti-detachment sliders 2102 are symmetrically arranged on the vertical plates above and below the connecting plate 2101, and an annular slide rail 19 adapted to the anti-detachment slider 2102 is provided on the sealing cover 3. When the mounting bracket 21 rotates relative to the sealing cover 3, the anti-detachment slider 2102 can rotate within the annular slide rail 19, making the connection between the mounting bracket 21 and the sealing cover 3 more stable, the mounting bracket 21 is not easy to fall off, and the safety of use is higher.

[0033] Detailed Implementation: In use, apple slices are fed into one of the apple slice carrying components 5, with the apple slices laid flat on the tray 22. The tray 22 is inserted between the plug-in seats 23. Then, the reduction motor 24 rotates one revolution, driving the rotating frame 4 to rotate 90°. After feeding, the apple slice carrying component 5 is aligned with the puffing tank 6. The electric slider 701 moves within the electric slide rail 15, driving the mounting clamp 7 to move, thus moving the puffing tank 6 to align with the sealing cover 3, completing the seal. Then, the air compressor 11 operates, introducing compressed air into the puffing tank 6. Simultaneously, the heating element inside the puffing tank 6 begins heating. After the puffing tank 6 has been heated and pressurized for a period of time, the pressure relief valve 10 opens, and the high-pressure gas instantly enters the vacuum chamber 12 through the first three-way valve 26 to complete the pressure relief. Then, the air pump... In step 16, the gas inside the puffing tank 6 is drawn into the vacuum chamber 12, creating a vacuum inside the puffing tank 6. At this time, the moisture inside the apple slices suddenly vaporizes and flashes, generating a strong vapor pressure difference, which causes the apple slice cells and tissues to expand, achieving the purpose of puffing and completing the processing of apple chips. After processing, the air compressor 11 operates, introducing air into the puffing tank 6 to release the vacuum. At this time, the compressed gas containing vapor in the vacuum chamber 12 comes into contact with the baffle plate 17, and the vapor condenses. Then the puffing tank 6 is reset, and the rotating frame 4 rotates again. The apple slices cool down on their own at the next two stations. The above operation is repeated to process the next batch of apple slices. During processing, the hot air remaining from the previous batch of processing can be guided to the air compressor 11 for secondary use through the second three-way valve 27.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately adapted to form other embodiments that can be understood by those skilled in the art.
