It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] See also Figure 1-6 A device for recycling secondary condensate from an evaporator for food production, the device comprising: a heat exchange tube 1, a fan-shaped cleaning scraper 4, a threaded rod 6, a linkage assembly, a switching assembly and a limit assembly, the heat exchange tube 1 is composed of a plurality of groups of main pipes 101, and the plurality of groups of main pipes 101 are connected end to end, food conveying pipes 2 are equidistantly installed inside the main pipe 101, cavities 3 are symmetrically installed at both ends of the main pipe 101, the cavities 3 are connected to the plurality of food conveying pipes 2, and the interior of the main pipe 101 is connected to the plurality of food conveying pipes 2. 2 is symmetrically slidably connected with a fan-shaped cleaning scraper 4 on the outside, and a switching spring 5 is fixedly connected to the middle of one of the fan-shaped cleaning scrapers 4, and a threaded rod 6 is slidably connected to the inside of the main pipe 101. The two fan-shaped cleaning scrapers 4 are respectively installed in cooperation with the threaded rod 6, and the two fan-shaped cleaning scrapers 4 move in opposite directions under the drive of the threaded rod 6. A linkage component for driving the threaded rod 6 to rotate is installed inside the cavity 3, a switching component for driving the threaded rod 6 to change the rotation direction is installed inside the cavity 3, and a limit component for limiting the threaded rod 6 is installed inside the cavity 3.

[0031] It should be noted that: food fluid injection: food fluid such as tomato fluid is injected from the inlet of the food conveying pipe 2; the injection port is located in the cavity 3 below the heat exchange tube 1 to ensure that the food fluid can smoothly enter the food conveying pipe 2;

[0032] Fluid flow: With the flow of condensed water and the increase in temperature in the food delivery pipe 2, the food fluid gradually flows forward in the pipe; this flow process not only realizes the delivery of food, but also ensures the uniformity of food during heating.

[0033] See also Figure 2 , Figure 3 and Figure 5 The linkage assembly includes: a fan blade 21, a driving bevel gear 22, a connecting shaft 23, a transmission bevel gear 24, a driving shaft 25 and a driving bevel gear 26. The fan blade 21 is rotatably connected inside the cavity 3, and the driving bevel gear 22 is fixedly connected at the axis of the fan blade 21. The connecting shaft 23 is rotatably connected inside the cavity 3. The two ends of the connecting shaft 23 are symmetrically fixedly connected with the transmission bevel gears 24, and one of the transmission bevel gears 24 is meshed with the driving bevel gear 22. The driving shaft 25 is rotatably connected inside the cavity 3, and the two ends of the driving shaft 25 are respectively fixedly connected with the driving bevel gears 26, and the other transmission bevel gear 24 is meshed with one of the driving bevel gears 26.

[0034] It should be noted that when the food fluid flows in the food conveying pipe 2, it drives the fan blades 21 in the cavity 3 to rotate;

[0035] The rotation of the fan blade 21 is transmitted to the switching bevel gear 31 through a series of gear transmission mechanisms including the driving bevel gear 22, the transmission bevel gear 24, the connecting shaft 23, the driving bevel gear 26, etc.;

[0036] See also Figure 4-5 The switching assembly includes: a switching bevel gear 31, a hollow bevel gear 32, a tooth 1 33, a tooth 2 34 and a double-sided tooth column 35. The switching bevel gear 31 is rotatably connected inside the cavity 3, and the hollow bevel gear 32 is rotatably connected inside the cavity 3. Another driving bevel gear 26 is meshed and connected with the switching bevel gear 31, and the switching bevel gear 31 is meshed and connected with the hollow bevel gear 32. One side of the driving bevel gear 26 close to the switching bevel gear 31 is fixedly connected with a tooth 1 33, and one side of the hollow bevel gear 32 is fixedly connected with a tooth 2 34. One end of the threaded rod 6 extends into the hollow bevel gear 32 and is fixedly connected with a double-sided tooth column 35, and the double-sided tooth column 35 is meshed and connected with the tooth 1 33.

[0037] It should be noted that the double-sided tooth column 35 is fixed to one end of the threaded rod 6 and rotates with the rotation of the threaded rod 6;

[0038] The tooth surface of the double-sided tooth column 35 interacts with the tooth surface of the switching bevel gear 31 to push the threaded rod 6 to move along its axial direction;

[0039] See also Figure 4 and Figure 6 The limiting assembly includes: a limiting ring 1 41, a limiting ring 2 42, a placement groove 43, a limiting spring 44 and a top column 45. The threaded rod 6 is provided with a limiting ring 1 41 and a limiting ring 2 42 at one end close to the double-sided tooth column 35. The inner wall of the cavity 3 is provided with a placement groove 43. The inner wall of the placement groove 43 is fixedly connected to the limiting spring 44. The inner wall of the placement groove 43 is slidably connected to the top column 45. One side of the top column 45 is fixedly connected to one end of the limiting spring 44, and the other end of the top column 45 is clamped with the limiting ring 1 41.

[0040] It should be noted that: in the initial state, the switching spring 5 does not directly contact the inside of the main pipe 101; it is in a certain pre-compression state, but has not reached the critical point of its elastic force release;

[0041] The switching spring 5 is compressed to a critical point: as the threaded rod 6 continues to rotate, the switching spring 5 is gradually compressed to a critical point where its elastic force is released; at this time, the elastic force of the switching spring 5 is greater than the elastic force of the limit spring 44, so that the top column 45 begins to contract;

[0042] The switching spring 5 releases the elastic force and the threaded rod 6 axially displaces: when the switching spring 5 is compressed to the critical point, it releases the stored elastic potential energy, pushing the threaded rod 6 to produce further axial displacement; in this process, the top column 45 is engaged with the limit ring 2 42.

[0043] See also Figure 7 , a condensed water recovery and utilization system, the condensed water recovery and utilization system includes any one of the above-mentioned embodiments of the evaporator secondary condensed water recovery and utilization device for food production.

[0044] The working principle of the secondary condensate recycling device and system for evaporators for food production provided by the present invention is as follows:

[0045] 1. Heat recovery

[0046] Condensate flow: The secondary condensate generated by the evaporator flows in from the upper inlet of the heat exchange tube 1 and flows along a plurality of main pipes 101 inside the heat exchange tube 1; these main pipes 101 are connected end to end to form a continuous fluid channel to ensure that the condensate can flow smoothly;

[0047] Heat energy transfer: During the flow of condensed water, the heat energy it carries is transferred to the food conveying pipe 2 located inside the heat exchange pipe 1 through the wall of the heat exchange pipe 1; the food conveying pipe 2 is filled with food fluid, such as tomato fluid, which gradually heats up under the heating of the condensed water;

[0048] Thermal energy utilization: Through the heat exchange process, the temperature of the condensed water decreases, while the temperature of the food fluid increases; this heat energy transfer mechanism not only realizes the effective utilization of the condensed water, but also saves the amount of heating steam used in the subsequent process, improving energy efficiency;

[0049] 2. Food Transportation

[0050] Food fluid injection: Food fluid (such as tomato fluid) is injected from the inlet of the food conveying pipe 2; the injection port is located in the cavity 3 below the heat exchange tube 1 to ensure that the food fluid can smoothly enter the food conveying pipe 2;

[0051] Fluid flow: With the flow of condensed water and the increase in temperature in the food delivery pipe 2, the food fluid gradually flows forward in the pipe; this flow process not only realizes the delivery of food, but also ensures the uniformity of food during heating;

[0052] 3. Automatic cleaning

[0053] Rotation of blade 21 and gear transmission:

[0054] When the food fluid flows in the food conveying tube 2, it drives the fan blades 21 in the cavity 3 to rotate;

[0055] The rotation of the fan blade 21 is transmitted to the switching bevel gear 31 through a series of gear transmission mechanisms (including the driving bevel gear 22, the transmission bevel gear 24, the connecting shaft 23, the driving bevel gear 26, etc.);

[0056] It is worth noting that the rotation directions of the driving bevel gear 26 and the hollow bevel gear 32 are opposite, and this reverse rotation provides the power basis for the subsequent cleaning mechanism;

[0057] The cooperation between the double-sided tooth column 35 and the threaded rod 6 is as follows:

[0058] The double-sided tooth column 35 is fixed to one end of the threaded rod 6 and rotates with the rotation of the threaded rod 6;

[0059] The tooth surface of the double-sided tooth column 35 interacts with the tooth surface of the switching bevel gear 31 to push the threaded rod 6 to move along its axial direction;

[0060] The double cooperation mechanism of the switching spring 5 and the top column 45:

[0061] Initial state: In the initial state, the switching spring 5 does not directly contact the inside of the main pipe 101; it is in a certain pre-compression state, but has not reached the critical point of its elastic force release;

[0062] The switching spring 5 is compressed to a critical point: as the threaded rod 6 continues to rotate, the switching spring 5 is gradually compressed to a critical point where its elastic force is released; at this time, the elastic force of the switching spring 5 is greater than the elastic force of the limit spring 44, so that the top column 45 begins to contract;

[0063] The switching spring 5 releases the elastic force and the threaded rod 6 moves axially: when the switching spring 5 is compressed to the critical point, it releases the stored elastic potential energy and pushes the threaded rod 6 to make further axial displacement; in this process, the top column 45 is engaged with the second limit ring 42;

[0064] The threaded rod 6 rotates in the reverse direction: Due to the engagement between the top column 45 and the second limiting ring 42, and the interaction between the double-sided tooth column 35 and the switching bevel gear 31, the threaded rod 6 rotates in the reverse direction at this time; this reverse rotation can be driven by the continued rotation of the switching bevel gear 31, or can be achieved by other transmission mechanisms;

[0065] Reciprocating motion of fan-shaped cleaning scraper 4:

[0066] Since the thread grooves on the two fan-shaped cleaning scrapers 4 have opposite thread directions, when the threaded rod 6 rotates forward or reverse, the two fan-shaped cleaning scrapers 4 will move in opposite directions respectively;

[0067] This reciprocating motion enables the fan-shaped cleaning scraper 4 to effectively scrape off the dirt on the outside of the food conveying pipe 2;

[0068] Dirt removal:

[0069] The scraped dirt is carried out of the heat exchange tube 1 along with the flow of condensed water and discharged through the drain port.

[0070] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
