[0001] The utility model relates to the technical field of slaughtering technology, in particular to a white stripe epidermis ultraviolet sterilization device. Background Art

[0002] The control of microorganisms on the body surface of white carcasses is the focus of sanitary control in the pig slaughtering industry. Since the feces, sewage and feed residues on the body surface of pigs during the breeding, transportation and slaughter process can all become carriers of microorganisms, exogenous microorganisms are the main factor causing the colony count of pig skin products to exceed the standard. If not handled properly, it can easily cause cross-contamination of other cuts such as meat and bones.

[0003] At present, the processes of body surface spraying, scalding, singeing, polishing and cleaning in slaughtering process can reduce the total number of bacterial colonies on the skin of white strips. However, after inspection, it was found that the number of microorganisms on the skin of white strips still reached 1x10 3 cfu / g to 1x10 4 cfu / g will further increase during the subsequent cutting, processing, transportation and storage, which may easily lead to excessive growth of microorganisms, resulting in meat spoilage and even the production of harmful substances, posing a threat to human health.

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The white stripe epidermis ultraviolet sterilization device of the present invention is described below with reference to the accompanying drawings.

[0022] Specifically, Figure 1 This is a front view of a white stripe epidermal ultraviolet sterilization device provided by the utility model.

[0023] like Figure 1 As shown, the white stripe epidermis ultraviolet sterilization device includes: an equipment bracket 100, a plurality of ultraviolet lamp tubes 200 and a light shield 300.

[0024] The equipment support 100 is arranged below the white strip travel track, and a left baffle 101 and a right baffle 102 are respectively installed on both sides of the equipment support 100; a plurality of ultraviolet lamp tubes 200 are vertically and evenly arranged and installed on the left baffle 101 and the right baffle 102, and are used to irradiate and sterilize a plurality of white strips suspended on the white strip travel track with ultraviolet light. A light shield 300 is arranged at the inlet and outlet ends of the equipment support to prevent ultraviolet light leakage.

[0025] In the actual implementation process, Figure 1 and 2 As shown in FIG. 1 , the equipment support 100 is divided into three parts: an inlet light-shielding channel, a sterilization channel, and an outlet light-shielding channel. Among them, a plurality of ultraviolet lamp tubes 200 are arranged on both sides of the sterilization channel, and light shields 300 are respectively arranged at the front end of the inlet light-shielding channel and the end of the outlet light-shielding channel. The white strips suspended on the white strip travel track first pass through the light shields 300 at the front end of the inlet light-shielding channel in turn to enter the inlet light-shielding channel, and then enter the sterilization channel provided with a plurality of ultraviolet lamp tubes 200. The ultraviolet lamps on both sides of the sterilization channel are used to evenly irradiate and sterilize the epidermis of the white strips. The irradiation needs to be continuous for 15s-30s, and the unit ultraviolet intensity of the epidermis of the white strips should be ≥5x10 4 Uw / cm 2 .s, in order to effectively kill the microorganisms, and then the sterilized white strips enter the exit light-shielding channel and sequentially pass through the light-shielding cover 300 at the end of the exit light-shielding channel to complete the sterilization of the white strip epidermis.

[0026] In some embodiments, both the left baffle 101 and the right baffle 102 are ultraviolet shielding plates.

[0027] In the actual implementation process, Figure 1 and 2 As shown, the left baffle 101 and the right baffle 102 in the equipment bracket 100 are made of ultraviolet shielding plates. The ultraviolet shielding plates can block the penetration of ultraviolet light to ensure that the operators or other equipment in the production workshop are protected from damage by ultraviolet rays, such as sunburn, equipment aging, etc. In addition, the ultraviolet shielding plates can reflect part of the ultraviolet rays, increase the intensity of ultraviolet radiation, and thereby improve the sterilization effect of white strips. They can also absorb part of the ultraviolet rays, thereby reducing the heat generated by the ultraviolet lamp, making the temperature in the production workshop more comfortable.

[0028] In the actual implementation process, Figure 1 and 2As shown, since the white strips to be sterilized are vertically suspended on the white strip travel track, in order to ensure that each white strip is irradiated by ultraviolet light as a whole, the utility model vertically and evenly arranges multiple ultraviolet lamp tubes 200 and installs them on the left baffle 101 and the right baffle 102, so that each white strip passes through each ultraviolet lamp tube and its surface is irradiated by ultraviolet light, thereby achieving the effect of improving the sterilization of white strips at a lower cost.

[0029] It should be noted that those skilled in the art may also evenly and horizontally install a plurality of ultraviolet lamp tubes 200 on the left baffle 101 and the right baffle 102 according to actual conditions, which is not specifically limited here.

[0030] In some embodiments, 15 254 nm ultraviolet lamps 200 are installed on both the left baffle 101 and the right baffle 102 .

[0031] In the actual implementation process, 15 ultraviolet lamps 200 capable of emitting 254nm and 300w power are installed on the left baffle 101 and the right baffle 102 of the equipment bracket 100 of the utility model, which can effectively sterilize the epidermis of white stripes.

[0032] In some embodiments, the present invention further includes:

[0033] At least four protection rods 103 are respectively mounted on the left baffle 101 and the right baffle 102, and the protection rods are parallel to each other, so as to stabilize the swinging white bar.

[0034] In the actual implementation process, Figure 2 As shown, when the white bar moves forward on the white bar travel track, the suspended white bar swings to a certain extent. When the amplitude is too large, it will hit the ultraviolet lamps on the left baffle 101 and the right baffle 102. Therefore, the utility model installs at least two mutually parallel protective rods on the left baffle 101, and installs at least two mutually parallel protective rods on the right baffle 102, which are in an "=" shape to prevent the swinging white bar from continuing to swing, and stably continue to move forward on the white bar travel track, thereby avoiding the occurrence of the white bar swinging damaging the ultraviolet lamp.

[0035] In some embodiments, the present invention further includes:

[0036] At least one motion sensor 104 is arranged at the inlet end and / or outlet end of the equipment bracket and is located outside the light shield 300, and is used to detect when multiple white strips hanging on the white strip travel track pass by, and turn on and / or turn off multiple ultraviolet lamps.

[0037] In the actual implementation process, Figure 1As shown, the utility model can install a motion sensor 104 at the inlet end of the equipment support 100, that is, at the front end of the inlet shading channel, and the motion sensor 104 is connected to the main switch of multiple ultraviolet lamp tubes 200. When multiple white strips suspended on the white strip travel track pass through the front end, the motion sensor 104 controls the multiple ultraviolet lamp tubes 200 to turn on. A motion sensor 104 can also be installed at the outlet end of the equipment support 100, that is, at the end of the outlet shading channel, and the motion sensor 104 is connected to the main switch of multiple ultraviolet lamp tubes 200. When multiple white strips suspended on the white strip travel track pass through the end, the motion sensor 104 controls the multiple ultraviolet lamp tubes 200 to turn off, thereby avoiding unnecessary energy consumption, reducing manual operation, and also avoiding that some white strips are not sterilized due to human misoperation or negligence, thereby improving the stability and reliability of the sterilization work.

[0038] In some embodiments, a black reflective plate is disposed on the inner side of the light shield 300 .

[0039] In the actual implementation process, in the utility model, a black reflective plate is provided on the inner side of the light shield 300 to increase the irradiation intensity of the ultraviolet light.

[0040] The working process of the white strip epidermal ultraviolet sterilization device proposed by the utility model is as follows: when a plurality of white strips hanging on the white strip travel track pass through the motion sensor 104 at the front end of the imported light shielding channel, a plurality of ultraviolet lamp tubes 200 are turned on, pass through the front end light shielding cover 300 and enter the sterilization channel, and the ultraviolet light of the sterilization channel sequentially irradiates and sterilizes the plurality of white strips hanging on the white strip travel track, and the effective irradiation time needs to be more than 18s to ensure that the ultraviolet radiation intensity per unit area is 1*104uw / cm 2 The above can effectively kill the microorganisms on the surface of the white strips. After the sterilization is completed, they enter the exit light-shielding channel in turn, pass through the end light-shielding cover 200, and after triggering the motion sensor 104 at the end of the exit light-shielding channel, the motion sensor 105 detects that there is no continuous white strip passing through, and then controls multiple ultraviolet lamps 200 to turn off.

[0041] According to the white strip epidermis ultraviolet sterilization device proposed by the utility model, after the white strips are shipped out of the warehouse, they enter the ultraviolet sterilization tunnel in sequence through the travel track, and the surface of the white strips is ultraviolet sterilized, so that the total number of bacteria on the white strip epidermis is reduced by two orders of magnitude, thereby achieving the purpose of epidermis sterilization and extending the shelf life of the product.
