Description

Technical Field

[0001] The present invention belongs to the technical field of table leftover food feed conversion equipment, and specifically relates to a high-temperature sterilization equipment and sterilization method for table leftover food feed conversion. Background Art

[0002] Table leftovers mainly come from commercial restaurants, including but not limited to canteens in catering units, schools, troops, factories, and office areas. These food residues are rich in various nutrients such as protein, starch, cellulose, fat, as well as various trace elements such as nitrogen, phosphorus, potassium, and calcium.

[0003] In order to convert food residues into utilizable feed, high-temperature sterilization is a key step. The principle of high-temperature sterilization is to heat the material to a certain temperature and maintain it for a certain period of time to completely kill the microorganisms and their spores therein. During this process, high temperature can destroy the cell structure of microorganisms, making them lose activity or die, thus ensuring the hygiene and safety of the feed.

[0004] However, when dealing with table leftovers, the food residues not only have a high moisture content, but also have a variety of residue types, which may include hard objects such as bones and shells. The presence of hard objects will not only cause serious wear to the equipment and reduce the service life of the equipment, but also due to the different sizes of the residues, the unbroken materials have a large volume, resulting in a reduction in heat transfer efficiency. During the high-temperature disinfection process, more energy is required to heat these materials to reach the temperature and time required for sterilization, increasing the energy consumption. Therefore, it is necessary to improve and optimize it. Summary of the Invention

[0005] To solve the problems of increased equipment wear and increased high-temperature disinfection energy consumption caused by the presence of hard objects and uneven residue sizes when dealing with table leftovers in the above background art, the present invention provides a high-temperature sterilization equipment and sterilization method for table leftover food feed conversion.

[0012] Preferably, the filtering assembly includes a filter plate fixedly installed on the inner wall of the outer box. The top of the filter plate is slidably connected to the bottom of the two telescopic plates.

[0013] Preferably, a number of transverse and longitudinal U-shaped grooves with upward openings are formed on the top of the filter plate. An oil collecting box is fixedly installed at the bottom of the filter plate. A hollow pipe is fixedly installed at the bottom of the oil collecting box. The bottom end of the hollow pipe extends outside the outer box and is fixedly connected to the outer box.

[0037] 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.

[0038] like Figures 1 to 11 As shown, the present invention provides a high-temperature sterilization device for converting table leftover food into feed, comprising an outer box 1, a feeding trough 101 is provided on the top of the outer box 1, and a filtering and feeding mechanism is provided inside the outer box 1;

[0039] The filtering and feeding mechanism includes a transmission component, a feeding component and a filtering component. The feeding component includes a rotating rod 2 and a rotating rod 21 rotatably mounted on the inner wall of the feed trough 101. One end of the rotating rod 2 and the rotating rod 21 extend out of the feed trough 101. The outer walls of the rotating rod 2 and the rotating rod 21 are respectively fixedly sleeved with baffles 4. The two baffles 4 are located inside the feed trough 101 and keep in contact with the inner wall of the feed trough 101. The outer wall of the rotating rod 2 is fixedly sleeved with a gear 1. 201 and gear two 202, a rotating rod three 3 is rotatably installed on the outer wall of the feed trough 101, a gear three 301 is fixedly sleeved on the outer wall of the rotating rod three 3, the gear three 301 is meshed with the gear one 201, and the outer walls of the rotating rod three 3 and the rotating rod two 21 are both provided with synchronous pulleys and are connected through a synchronous belt 6, a support plate 7 is fixedly installed on the outer wall of the feed trough 101, a rack 5 is slidably installed on the outer wall of the support plate 7, and the rack 5 is meshed with the gear two 202.

[0040] By designing a filtering and feeding mechanism, and integrating a transmission component, a feeding component and a filtering component, the components work together without frequent manual intervention. In the feeding component, the meshing of the rotating rod 1 2, the rotating rod 21 and the baffle 4 thereon, the gear 1 201, the gear 202 and the rotating rod 3 3 and the gear 3 301 thereon, as well as the transmission connection of the synchronous belt 6, the automatic feeding of the residue is realized, and the filtration blockage problem of the filter plate 12 caused by too much material being fed at the same time is effectively prevented. By accurately controlling the feeding speed and amount, it is ensured that the filter plate 12 can continuously and stably separate oil and water and filter solid residue, thereby improving the efficiency and reliability of the entire processing process.

[0041] like Figures 7 to 9As shown in the figure, the transmission assembly includes a motor 8 fixedly installed on the outer wall of the outer box 1. The output shaft of the motor 8 extends into the outer box 1 and is rotatably connected to the outer box 1. A lead screw 9 is rotatably installed inside the outer box 1. One end of the lead screw 9 is fixedly connected to the output shaft of the motor 8. A cylinder 91 and two telescopic plates 10 are respectively sleeved on the outer wall of the lead screw 9 in a threaded manner. A limit slide bar 11 is fixedly installed on the inner wall of the outer box 1. The limit slide bar 11 respectively penetrates through the two telescopic plates 10 and is slidably connected to the two telescopic plates 10. A first thread groove 92 is opened on the outer wall of the lead screw 9 near the motor 8, and a second thread groove 93 is opened at the end far from the motor 8. The second thread groove 93 is composed of two sets of thread grooves in opposite directions. Both telescopic plates 10 are threadedly connected to the second thread groove 93. A convex block 901 is fixedly installed inside the cylinder 91. The convex block 901 is adapted to the first thread groove 92. A connecting rod 911 is fixedly installed on the outer wall of the cylinder 91. The top end of the connecting rod 911 is fixedly connected to the bottom end of the rack 5. A rectangular groove 102 is opened on the outer wall of the outer box 1. The connecting rod 911 penetrates through the rectangular groove 102 and is slidably connected to the rectangular groove 102.

[0042] Driving the lead screw 9 to rotate through the motor 8 ensures the stable transmission of power; the second thread groove 93 opened at the other end is composed of two sets of thread grooves in opposite directions, enabling the two telescopic plates 10 to move simultaneously but in opposite directions. The first thread groove 92 opened at the end of the lead screw 9 near the motor 8 is adapted to the convex block 901 inside the cylinder 91, ensuring that the cylinder 91 can move smoothly with the rotation of the lead screw 9. Connecting the cylinder 91 and the rack 5 through the connecting rod 911 realizes the linkage between the transmission assembly and the feeding assembly. When the cylinder 91 moves, the rack 5 also moves accordingly, thereby driving the feeding assembly.

[0043] As Figures 6 to 11 shown in the figure, the filtering assembly includes a filter plate 12 fixedly installed on the inner wall of the outer box 1. The top of the filter plate 12 is slidably connected to the bottom of the two telescopic plates 10. Several horizontal and vertical U-shaped grooves with upward openings are opened on the top of the filter plate 12. An oil collecting box 1201 is fixedly installed at the bottom of the filter plate 12. A hollow pipe 1202 is fixedly installed at the bottom of the oil collecting box 1201. The bottom end of the hollow pipe 1202 extends outside the outer box 1 and is fixedly connected to the outer box 1. The bottom of the front section of several horizontal U-shaped grooves is designed to be inclined, and the side far from the oil collecting box 1201 is higher than the other side. The bottom of the side section of several vertical U-shaped grooves is designed with two high sides and a low middle.

[0044] Through the filter plate 12 fixedly installed on the inner wall of the outer box 1, the oil-water separation of the remaining food on the dining table is realized. Several transverse and longitudinal U-shaped grooves are designed at the top of the filter plate 12. The bottom of the transverse U-shaped groove is designed to be inclined, with the side far from the oil collecting box 1201 being higher than the other side. This design enables the smooth flow of the oil-water mixture and makes it easier to be guided into the oil collecting box 1201. The bottom of the side profile of the longitudinal U-shaped groove is designed with higher sides and a lower middle, enhancing the flow effect, enabling the liquid to flow smoothly into the transverse U-shaped groove, and being able to discharge the collected grease out of the outer box 1 for subsequent treatment.

[0045] As Figure 5 shown, one side of the rack 5 close to the support plate 7 is recessed and adapted to the outer wall of the support plate 7. Rectangular blocks are designed on both sides of the rack 5, and the second gear 202 is located in the middle of the two rectangular blocks.

[0046] By designing one side of the rack 5 close to the support plate 7 to be recessed and tightly adapted to the outer wall of the support plate 7, the stable sliding of the rack 5 on the support plate 7 is ensured, improving the accuracy of transmission. This enables the rack 5 to always maintain close contact with the support plate 7 during the sliding process, avoiding transmission errors caused by shaking or deviation. Moreover, rectangular blocks are designed on both sides of the rack 5, making the second gear 202 located in the middle of the two rectangular blocks, ensuring a more stable and reliable meshing between the second gear 202 and the rack 5 and reducing transmission failures caused by poor meshing.

[0047] A high-temperature sterilization method for feed conversion of the remaining food on the dining table. The specific steps of this method include:

[0048] S1, crushing and screening: Since the remaining food on the dining table may contain foreign objects such as chopsticks, plastic bags, and bottle caps, it is necessary to first process it through a crushing and screening system to remove the non-recyclable components and evenly crush the kitchen waste into small particles for subsequent treatment;

[0049] S2, solid-liquid separation: The kitchen waste after crushing and screening enters the solid-liquid separation system, and the moisture and salt are removed through methods such as screw extrusion; the volume of the dehydrated waste decreases, the moisture content decreases, and a large amount of salt is also removed, providing favorable conditions for subsequent high-temperature sterilization and feed conversion treatment;

[0050] S3, feed raw material generation and high-temperature sterilization: The dehydrated kitchen waste enters the feed raw material generation system and is subjected to high-temperature sterilization treatment through indirect heating; the heating temperature is controlled between 90°C and 120°C to ensure the effective killing of harmful bacteria while ensuring that the nutritional components of the raw materials are not damaged; this step is the key link in the feed conversion treatment and is directly related to the safety and quality of the feed products;

[0051] S4. Cooling and screening: The products after high-temperature sterilization are transported to the cooling and screening system for cooling treatment and secondary screening. During the cooling process, small foreign matters such as possible metals and bones can be further removed to ensure the quality of feed raw materials. At the same time, the cooled products are also easier to be crushed and processed subsequently.

[0052] The working principle and usage process of the present invention:

[0053] The untreated food residues are put into the outer box 1 through the feeding trough 101;

[0054] Start the motor 8. The output shaft of the motor 8 rotates to drive the lead screw 9 to rotate. Through the threaded connection between the convex block 901 and the first threaded groove 92, the rotation of the lead screw 9 drives the cylinder 91 to move horizontally along the axis of the lead screw 9. When the lead screw 9 rotates, the two telescopic plates 10 threadedly connected to the second threaded groove 93 approach each other along the axis of the lead screw 9 until they are located at the center of the filter plate 12. The cylinder 91 drives the rack 5 to move through the connecting rod 911. The rack 5 meshes with the second gear 202, driving the second gear 202, the first rotating rod 2 and the first gear 201 to rotate. The first gear 201 meshes with the third gear 301, driving the third gear 301 and the third rotating rod 3 to rotate. Through the transmission of the synchronous belt 6, the third rotating rod 3 drives the second rotating rod 21 to rotate, so that the two baffles 4 are opened in a positive "eight" shape, and the residues smoothly fall onto the top of the filter plate 12;

[0055] The residues enter the oil collecting box 1201 through the U-shaped groove design at the top of the filter plate 12, and the key liquid converges and is discharged through the hollow tube 1202. The smaller residues continue to enter the next process, and the larger residues remain on the top of the filter plate 12;

[0056] Start the motor 8 again to make the output shaft rotate in the reverse direction, driving the two baffles 4 to rotate back to the initial state in an inverted "eight" shape, closing the channel for the residues to enter the outer box 1. At the same time, the two telescopic plates 10 move away from each other along the axis direction of the lead screw 9, pushing the larger residues on the top of the filter plate 12 into the crushing area for crushing, and then entering the next process.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
