Description

Technical Field

[0001] This invention relates to the field of sterilization and disinfection devices, specifically a food sterilization and disinfection device for food safety. Background Technology

[0002] Food sterilization and disinfection equipment is a specialized device used to kill or inhibit microorganisms and some parasites in food, in order to extend the shelf life of food, ensure food safety, and improve food quality. Its core function is to destroy the cell structure or metabolic system of microorganisms through physical, chemical, or biological methods, so that they lose their activity or reproductive ability, thereby meeting the hygiene requirements of food processing, storage, and distribution, such as tunnel sterilizers. Currently, during the processing of nuts in tunnel sterilization machines, the nuts are heated by ultraviolet light, causing the nuts to release oil. This oil forms stains on the conveyor belt surface of the sterilization machine, leading to the growth of microorganisms and cross-contamination, which affects the hygienic quality of the next batch of nuts. Summary of the Invention

[0003] The purpose of this invention is to provide a food sterilization and disinfection device for food safety. Multiple sets of first nozzles spray water from inside the brush rod onto the conveyor belt inside the tunnel sterilizer. In conjunction with a second reciprocating screw, the brush rod is driven to move back and forth through a threaded sleeve. The brush rod cleans the bottom of the conveyor belt inside the tunnel sterilizer, preventing the oil released from nuts after being heated by ultraviolet light in the tunnel sterilizer from adhering to the surface of the conveyor belt and forming oil stains. This would lead to the growth of microorganisms on the conveyor belt, causing cross-contamination and affecting the hygienic quality of subsequent batches of nuts, thus solving the problems mentioned in the background art.

[0006] Preferably, one set of the drive rollers penetrates the frame of the feed end of the tunnel sterilizer, and one end of one set of the drive rollers is fixedly connected to one end of the transmission rod via a second synchronous belt.

[0007] Preferably, the gearbox is fixedly installed inside the tunnel sterilizer, and the gearbox has two sets of meshing bevel gears inside.

[0008] Preferably, the other end of the transmission rod penetrates the outer surface of the gearbox, and the other end of the transmission rod is fixedly connected to one of the sets of bevel teeth; one end of the second reciprocating screw penetrates the outer surface of the gearbox, and one end of the second reciprocating screw is fixedly connected to another set of bevel teeth.

[0009] Preferably, the second reciprocating screw and the threaded sleeve are connected by a ball nut pair, and the threaded sleeve is slidably connected to the second reciprocating screw.

[0010] Preferably, a water pump is fixedly installed inside the collection box, and a hose is fixedly connected to the output end of the water pump.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The water pump draws water from the collection tank, which is then transmitted through a hose to the brush rod. Multiple first nozzles spray the water from inside the brush rod onto the conveyor belt inside the tunnel sterilizer. In conjunction with the second reciprocating screw, the brush rod moves back and forth through the threaded sleeve. The brush rod cleans the bottom of the conveyor belt inside the tunnel sterilizer, preventing the oil that is released from the nuts after being heated by ultraviolet light from adhering to the surface of the conveyor belt and forming oil stains. This would lead to the growth of microorganisms on the conveyor belt, causing cross-contamination and affecting the hygienic quality of subsequent batches of nuts.

[0015] 2. Two sets of eccentric rollers drive the vibrating conveyor belt to vibrate, which in turn causes the nuts to vibrate. This ensures that the nuts are evenly distributed on the conveyor belt inside the tunnel sterilizer, preventing them from accumulating in certain areas and overloading the conveyor belt, which would affect the quality of sterilization.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 3 The present invention provides a food sterilization and disinfection device for food safety, including a tunnel sterilizer 1. An auxiliary component 2 is installed inside the frame of the feed end of the tunnel sterilizer 1. The auxiliary component 2 includes a vibrating transmission belt 201 rotatably installed inside the frame of the feed end of the tunnel sterilizer 1. Two sets of drive rollers 202 are rotatably installed inside the vibrating transmission belt 201. One end of each set of drive rollers 202 is connected to an eccentric roller 205 through a first synchronous belt 204. The staff pours the nuts onto the vibrating conveyor belt 201 and starts the motor 203. The motor 203 drives one set of drive rollers 202 to rotate, and the two sets of drive rollers 202 work together to drive the vibrating conveyor belt 201 to rotate. Both sets of drive rollers 202 drive the eccentric rollers 205 to rotate through the first synchronous belt 204. The two sets of eccentric rollers 205 drive the vibrating conveyor belt 201 to vibrate. The vibrating conveyor belt 201 vibrates the nuts, so that the nuts are evenly distributed on the conveyor belt inside the tunnel sterilizer 1. This prevents the nuts from accumulating on the conveyor belt inside the tunnel sterilizer 1, which would overload the conveyor belt and affect the sterilization quality of the nuts. Please see Figures 4 to 5 The tunnel sterilizer 1 is internally equipped with a cleaning component 3, which includes a collection box 301. A brush rod 304 is connected inside the collection box 301. Multiple sets of first nozzles 306 are mounted on the brush rod 304. A threaded sleeve 305 is fixedly installed on one side of the brush rod 304. A second reciprocating screw 316 is connected inside the threaded sleeve 305. One end of the second reciprocating screw 316 is connected to a gearbox 307. A transmission rod 308 is connected to one side of the gearbox 307. The end is connected to one end of one set of drive rollers 202 via the second synchronous belt 206. One end of the second reciprocating screw 316 is fixedly connected to the first reciprocating screw 310. A threaded disc 311 is slidably connected to the first reciprocating screw 310. A piston tube 312 is provided on the outer surface of the threaded disc 311. A nozzle 314 is connected to one side of the piston tube 312. Multiple sets of second nozzles 315 are provided on the nozzle 314. The outer surface of the nozzle 314 is fixedly connected to the outer surface of the brush rod 304 via a connecting rod. While the vibrating conveyor belt 201 vibrates the nuts, one set of drive rollers 202 drives the transmission rod 308 to rotate via the second synchronous belt 206. Since the gearbox 307 has two sets of meshing bevel gears, the transmission rod 308 is driven by these two sets of bevel gears, thus driving the second reciprocating screw 316 to rotate. Because the second reciprocating screw 316 is connected to the threaded sleeve 305 via a ball nut pair, the second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305. At this time, the operator starts the water pump 302 inside the collection box 301, and the water pump 302 draws out the collected... The water source inside the box 301 is transmitted to the brush rod 304 through the hose 303. The water source inside the brush rod 304 is then sprayed onto the conveyor belt inside the tunnel sterilizer 1 through multiple sets of first nozzles 306. In conjunction with the second reciprocating screw 316, the brush rod 304 is driven to reciprocate through the threaded sleeve 305. The brush rod 304 cleans the bottom of the conveyor belt inside the tunnel sterilizer 1, preventing the oil that is released from the nuts after the tunnel sterilizer 1 is heated by ultraviolet light from adhering to the surface of the conveyor belt of the tunnel sterilizer 1, forming oil stains, which would cause microorganisms to grow on the conveyor belt of the sterilizer, causing cross-contamination and affecting the hygienic quality of subsequent batches of nuts. When the second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305, one end of the second reciprocating screw 316 drives the first reciprocating screw 310 to rotate. Since the first reciprocating screw 310 is connected to the threaded disc 311 through a ball nut pair, and the protrusion on the outer surface of the threaded disc 311 slides on the groove inside the piston tube 312, the first reciprocating screw 310 drives the threaded disc 311 to reciprocate inside the piston tube 312. The threaded disc 311 squeezes the gas inside the piston tube 312, and the gas is transmitted to the nozzle 314 through the telescopic tube 313. The gas inside the nozzle 314 is sprayed onto the conveyor belt inside the cleaned tunnel sterilizer 1 through the second nozzle 315. The nozzle 314 will move back and forth synchronously through the connecting rod to help the cleaned conveyor belt to dry, preventing water stains from remaining on the conveyor belt inside the tunnel sterilizer 1, which may cause microbial growth, resulting in secondary contamination of nuts or even mold and spoilage. Additionally, the telescopic tube 313 extends and retracts along with the movement of the nozzle 314 to prevent the telescopic tube 313 from affecting the reciprocating movement of the nozzle 314.

[0021] It should be noted that the motor 203 is used to drive one set of drive rollers 202 to rotate, and the two sets of drive rollers 202 cooperate to drive the vibrating transmission belt 201 to rotate.

[0022] In an optional embodiment, one set of drive rollers 202 penetrates the frame of the feed end of the tunnel sterilizer 1, and one end of one set of drive rollers 202 is fixedly connected to one end of the transmission rod 308 via a second synchronous belt 206.

[0023] It should be noted that while the vibrating conveyor belt 201 drives the nuts to vibrate, one set of drive rollers 202 drives the transmission rod 308 to rotate via the second synchronous belt 206.

[0024] In an optional embodiment, the gearbox 307 is fixedly installed inside the tunnel sterilizer 1, and the gearbox 307 has two sets of meshing bevel gears inside.

[0025] It should be noted that the two sets of meshing bevel teeth are used to transmit the power of the transmission rod 308 to the second reciprocating screw 316.

One end of the second reciprocating screw 316 penetrates the outer surface of the gearbox 307, and one end of the second reciprocating screw 316 is fixedly connected to another set of bevel teeth.

[0027] It should be noted that since there are two sets of meshing bevel gears inside the gearbox 307, the transmission rod 308 drives the second reciprocating screw 316 to rotate through the two sets of bevel gears.

[0028] In an optional embodiment, the second reciprocating screw 316 is connected to the threaded sleeve 305 via a ball nut pair, and the threaded sleeve 305 is slidably connected to the second reciprocating screw 316.

[0029] It should be noted that since the second reciprocating screw 316 is connected to the threaded sleeve 305 through a ball nut pair, the second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305.

[0030] In an optional embodiment, a water pump 302 is fixedly installed inside the collection box 301, and a hose 303 is fixedly connected to the output end of the water pump 302. One end of the hose 303 passes through the inside of the collection box 301 and the outer surface of the tunnel sterilizer 1 in sequence, and one end of the hose 303 is connected to the inside of the brush rod 304.

[0031] It should be noted that the staff will start the water pump 302 inside the collection box 301. The water pump 302 is used to draw water from inside the collection box 301. The water is then transferred to the brush rod 304 through the hose 303.

[0032] In an optional embodiment, one end of the second reciprocating screw 316 passes through another set of bevel gears and the interior of the gearbox 307 in sequence, and one end of the second reciprocating screw 316 is fixedly connected to one end of the first reciprocating screw 310.

[0033] It should be noted that when the second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305, one end of the second reciprocating screw 316 drives the first reciprocating screw 310 to rotate.

[0034] In an optional embodiment, one end of the first reciprocating screw 310 passes through the interior of the piston tube 312, and the first reciprocating screw 310 is connected to the threaded disc 311 through a ball nut pair. The piston tube 312 has a groove inside, and the outer surface of the threaded disc 311 has a protrusion that slides inside the groove.

[0035] It should be noted that, since the first reciprocating screw 310 is connected to the threaded disc 311 through a ball nut pair, and the protrusion on the outer surface of the threaded disc 311 slides on the groove inside the piston tube 312, the first reciprocating screw 310 drives the threaded disc 311 to reciprocate inside the piston tube 312.

[0036] In an optional embodiment, the outer surface of the piston tube 312 is connected to a telescopic tube 313, one end of which is connected to the outer surface of the nozzle 314.

[0037] It should be noted that the telescopic tube 313 extends and retracts along with the movement of the nozzle 314 to prevent the telescopic tube 313 from affecting the reciprocating movement of the nozzle 314.

[0038] Working principle: The worker pours the nuts onto the vibrating conveyor belt 201 and starts the motor 203. The motor 203 drives one set of drive rollers 202 to rotate, and the two sets of drive rollers 202 work together to drive the vibrating conveyor belt 201 to rotate. Both sets of drive rollers 202 drive the eccentric rollers 205 to rotate through the first synchronous belt 204. The two sets of eccentric rollers 205 drive the vibrating conveyor belt 201 to vibrate, and the vibrating conveyor belt 201 drives the nuts to vibrate, so that the vibrating conveyor belt 201 carries the nuts to be evenly distributed on the conveyor belt inside the tunnel sterilizer 1. While the vibrating conveyor belt 201 vibrates the nuts, one set of drive rollers 202 drives the transmission rod 308 to rotate via the second synchronous belt 206. Since the gearbox 307 has two sets of meshing bevel gears, the transmission rod 308 is driven by these two sets of bevel gears, thus driving the second reciprocating screw 316 to rotate. Because the second reciprocating screw 316 is connected to the threaded sleeve 305 via a ball nut pair, the second reciprocating screw 316 drives the brush rod 30 through the threaded sleeve 305. 4. The water pump 302 inside the collection box 301 is activated. The water pump 302 draws water from the collection box 301. The water is then transferred to the brush rod 304 through the hose 303. The water inside the brush rod 304 is sprayed onto the conveyor belt inside the tunnel sterilizer 1 through multiple sets of first nozzles 306. The second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305. The brush rod 304 cleans the bottom of the conveyor belt inside the tunnel sterilizer 1. When the second reciprocating screw 316 drives the brush rod 304 to reciprocate through the threaded sleeve 305, one end of the second reciprocating screw 316 drives the first reciprocating screw 310 to rotate. Since the first reciprocating screw 310 is connected to the threaded disc 311 through a ball nut pair, and the protrusion on the outer surface of the threaded disc 311 slides on the groove inside the piston tube 312, the first reciprocating screw 310 drives the threaded disc 311 to reciprocate inside the piston tube 312. The threaded disc 311 compresses the gas inside the piston tube 312, and the gas is transmitted to the nozzle 314 through the telescopic tube 313. The gas inside the nozzle 314 is sprayed onto the conveyor belt inside the cleaned tunnel sterilizer 1 through the second nozzle 315. The nozzle 314 will move back and forth synchronously through the connecting rod to assist the cleaned conveyor belt in drying.
