Abstract
Description
Technical Field
[0001] This utility model relates to the field of food purification technology, specifically to a food purification device. Background Technology
[0002] Food purification is an important food processing technology that ensures food safety and extends shelf life. Essentially, food purification and sterilization is the process of reducing or eliminating harmful microorganisms in food through physical or chemical methods. In the production and processing of transparently packaged foods, photocatalytic sterilization furnaces are used to purify and sterilize the food through photocatalytic irradiation.
[0003] The aforementioned device does not have the structure of double-sided irradiation for catalytic purification and sterilization in photocatalytic sterilization furnaces. As a result, existing photocatalytic sterilization furnaces use a double-sided irradiation method from top to bottom to ensure sterilization effect. However, since the movement of food requires the use of a conveyor belt, although many fine holes are made in the conveyor belt to ensure that the bottom of the food can be photocatalytically irradiated, the effect is not good and there are blind spots. Based on the shortcomings of the existing technology, this utility model designs a food purification device. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a food purification device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A food purification device includes a purification device body, a second photocatalytic lamp tube is disposed inside the purification device body, a light-transmitting plate is fixedly connected to the upper surface of the purification device body and the light-transmitting plate is disposed directly above the second photocatalytic lamp tube, a protective cover is disposed on the upper surface of the purification device body, and a moving mechanism is disposed inside the protective cover to facilitate the second photocatalytic lamp tube and the light-transmitting plate to perform photocatalytic purification and sterilization on the bottom of the food.
[0007] The moving mechanism includes a lifting frame, a first rotating roller, a rubber transfer belt, a lifting cylinder, a second rotating roller, a motor, a transmission wheel, and a belt. The lifting frame is movably raised and lowered inside the protective cover. The first rotating roller is rotatably connected inside the lifting frame. The rubber transfer belt is sleeved on the first rotating roller. The lifting cylinder is fixedly installed on the upper surface of the protective cover. The second rotating roller is rotatably connected to the inner side of the lifting frame, and the second rotating roller is rotatably connected to the upper surface of the rubber transfer belt. The motor is fixedly installed on the upper surface of the lifting frame. The transmission wheel is fixedly connected to the output end of the motor. The belt drive is sleeved on the transmission wheel and the second rotating roller.
[0008] As a preferred embodiment of this utility model, a transmission roller is rotatably connected inside the main body of the purification device, a mesh conveyor belt is driven and sleeved on the transmission roller, a first photocatalytic lamp is installed inside the main body of the purification device, a control panel is fixedly installed on one side of the main body of the purification device, and an inspection door is provided on one side of the main body of the purification device.
[0009] As a preferred technical solution of this utility model, the protective cover is provided with light-blocking side plates that slide and lift on both sides, and the light-blocking side plates are provided with adjustment grooves. The protective cover is threaded with adjustment bolts on both sides, and a third photocatalytic lamp tube is provided inside the protective cover.
[0010] As a preferred embodiment of this utility model, the first photocatalytic lamp tube is disposed on the inner side of the mesh conveyor belt, which is a mesh-type light-transmitting conveyor belt.
[0011] As a preferred embodiment of this invention, the third photocatalytic lamp is positioned above the mesh conveyor belt.
[0012] As a preferred embodiment of this utility model, the adjusting bolt is clamped and disposed on the light-blocking side plate and the adjusting groove.

[0014] As a preferred embodiment of this utility model, the second rotating roller is connected to the upper surface of the rubber conveyor belt, and the moving mechanism is located above the second photocatalytic lamp tube and the light-transmitting plate.
[0015] The present invention adopts the above technical solution and has the following beneficial effects: This food purification device places bagged food on a mesh conveyor belt from the entrance of the purification device body and protective cover. The working transmission roller moves the bagged food into the interior of the purification device body and protective cover. The food is then subjected to photocatalytic sterilization treatment using a first photocatalytic lamp and adjusting bolts. After the first-stage sterilization is completed, the bagged food on the mesh conveyor belt is transferred to a light-transmitting plate. At this time, the lifting frame, the first rotating roller, and the rubber transfer belt, which are pre-adjusted by the lifting cylinder, come into contact with the upper surface of the food. The motor drives the second rotating roller to rotate through the transmission wheel and belt, causing the rubber transfer belt to rotate and move the bagged food in contact with it on the light-transmitting plate. The bottom of the bagged food is then subjected to photocatalytic sterilization treatment using a second photocatalytic lamp. Finally, the bagged food with the sterilized bottom enters the next section of the mesh conveyor belt for further photocatalytic sterilization before being transferred out of the purification device body and protective cover. This device facilitates photocatalytic sterilization of the bottom of the food as well. Attached Figure Description

[0022] like Figure 1-5 As shown, this utility model discloses a food purification device, including a purification device body 1. A second photocatalytic lamp 104 is installed inside the purification device body 1. A light-transmitting plate 105 is fixedly connected to the upper surface of the purification device body 1, and the light-transmitting plate 105 is positioned directly above the second photocatalytic lamp 104. A protective cover 2 is installed on the upper surface of the purification device body 1. A moving mechanism 3 is installed inside the protective cover 2 to facilitate photocatalytic purification and sterilization of the bottom of the food by assisting the second photocatalytic lamp 104 and the light-transmitting plate 105. A transmission roller 101 is rotatably connected inside the purification device body 1. A mesh conveyor belt 102 is driven and sleeved on the transmission roller 101. A first photocatalytic lamp 103 is installed inside the purification device body 1. A control panel 106 is fixedly installed on one side of the purification device body 1. An inspection door 107 is provided on one side of the purification device body 1. The first photocatalytic lamp 103 is located inside the mesh conveyor belt 102, which is a mesh-type light-transmitting conveyor belt.
[0023] By setting up a mesh conveyor belt 102 and a first photocatalytic lamp tube 103, and the mesh conveyor belt 102 being a mesh-type light-transmitting conveyor belt, the bottom of the bagged food can also be sterilized by photocatalytic irradiation. By setting up a second photocatalytic lamp tube 104 and a light-transmitting plate 105, the bagged food can be sterilized by more detailed photocatalytic irradiation.
[0024] like Figure 4-5As shown, the moving mechanism 3 includes a lifting frame 301, a first rotating roller 302, a rubber conveyor belt 303, a lifting cylinder 304, a second rotating roller 305, a motor 306, a transmission wheel 307, and a belt 308. The lifting frame 301 is movably raised and lowered inside the protective cover 2. The first rotating roller 302 is rotatably connected inside the lifting frame 301. The rubber conveyor belt 303 is sleeved on the first rotating roller 302. The lifting cylinder 304 is fixedly installed on the upper surface of the protective cover 2. The second rotating roller 305 is rotatably connected to the inner side of the lifting frame 301. The motor 306... 6 is fixedly installed on the upper surface of the lifting frame 301, and the second roller 305 is rotatably connected to the upper surface of the rubber transfer belt 303; the transmission wheel 307 is fixedly connected to the output end of the motor 306, and the belt 308 is driven and sleeved on the transmission wheel 307 and the second roller 305; the telescopic end of the lifting cylinder 304 passes through the top of the protective cover 2 and is fixedly connected to the upper surface of the lifting frame 301; the second roller 305 is rotatably connected to the upper surface of the rubber transfer belt 303; and the moving mechanism 3 is located above the second photocatalytic lamp tube 104 and the light-transmitting plate 105.
[0025] By setting up a lifting frame 301, a first rotating roller 302, a rubber conveyor belt 303, a lifting cylinder 304, a second rotating roller 305, a motor 306, and a transmission wheel 307, and with the above structure positioned above the second photocatalytic lamp 104 and the light-transmitting plate 105, the lifting cylinder 304 driven by the motor 306 can rotate the rubber conveyor belt 303 after the bagged food is transferred onto the light-transmitting plate 105. This allows the rotating rubber conveyor belt 303 to slide the bagged food on the light-transmitting plate 105, and the second photocatalytic lamp 104 can irradiate and sterilize the bottom of the food. The lifting cylinder 304 can also be used to control the rubber conveyor belt 303 to adapt to foods of different thicknesses.
[0026] like Figure 3 As shown, light-blocking side plates 201 are slidably and vertically installed on both sides of the protective cover 2. An adjustment groove 202 is provided on the light-blocking side plate 201. Adjustment bolts 203 are threadedly connected to both sides of the protective cover 2. A third photocatalytic lamp tube 204 is installed inside the protective cover 2. The third photocatalytic lamp tube 204 is located above the mesh conveyor belt 102. The adjustment bolts 203 are clamped through and held on the light-blocking side plate 201 and the adjustment groove 202.
[0027] By setting up a protective cover 2 and a light-blocking side plate 201, the light will not shine outward and affect the operator during the photocatalytic irradiation sterilization process of food. By setting up an adjustment groove 202 and an adjustment bolt 203, the height of the light-blocking side plate 201 can be adjusted, and the opening height on both sides of the protective cover 2 can be adjusted according to the thickness of different bagged foods. By setting up a third photocatalytic lamp tube 204, the photocatalytic sterilization treatment of bagged food can be carried out in conjunction with the mesh conveyor belt 102 and the first photocatalytic lamp tube 103.
[0028] The working principle of this utility model is as follows: When the food purification device is used, in the initial state, a transmission roller 101 and a mesh conveyor belt 102 are respectively set at both ends of the upper surface of the main body 1 of the purification device, and a third photocatalytic lamp tube 204 is respectively installed at both ends inside the protective cover 2, so as to carry out photocatalytic sterilization treatment on the food entering the protective cover 2. A second photocatalytic lamp tube 104 is installed below the light-transmitting plate 105 set between the two sets of mesh conveyor belts 102. At the same time, a lifting frame 301, a first rotating roller 302 and a rubber transfer belt 303 are set above the second photocatalytic lamp tube 104 and the light-transmitting plate 105. The rubber transfer belt 303 is driven by a motor 306, a transmission wheel 307 and a belt 308, so as to carry out moving photocatalytic sterilization treatment on the bottom of the food with poor photocatalytic effect.
[0029] When photocatalytic sterilization of the bottom of the food is required, the bagged food is first placed on the mesh conveyor belt 102 from the entrance of the purification device body 1 and protective cover 2. The working transmission roller 101 moves the bagged food into the purification device body 1 and protective cover 2, where the first photocatalytic lamp tube 103 and adjusting bolt 203 perform photocatalytic sterilization on the food. After the one-stage sterilization is completed, the bagged food on the mesh conveyor belt 102 is transferred to the light-transmitting plate 105. At this time, the lifting frame 301, the first rotating roller 302, and the rubber transfer belt 303, which are pre-adjusted by the lifting cylinder 304, come into contact with the upper surface of the food. The motor 306 drives the second rotating roller 305 to rotate through the transmission wheel 307 and belt 308, causing the rubber transfer belt 303 to rotate. The rotating mechanism moves the bagged food in contact with it on the light-transmitting plate 105, and the bottom of the bagged food is photocatalytically sterilized using the second photocatalytic lamp tube 104. Finally, the sterilized bagged food enters the next section of the mesh conveyor belt 102 for further photocatalytic sterilization before being transferred out of the purification device body 1 and protective cover 2. This device facilitates photocatalytic sterilization of the bottom of the food as well. The above describes a specific embodiment of this utility model. However, those skilled in the art should understand that this is merely an example. Various changes or modifications can be made to this embodiment without departing from the principle and essence of this utility model, and all such changes and modifications fall within the protection scope of this utility model.
