Description

Technical Field

[0001] The utility model relates to a sterilizer, in particular to a stable sterilizer, belonging to the technical field of yogurt sterilization equipment. Background Art

[0002] Yogurt is a dairy product made from the milk of cattle such as yellow cattle and yaks in the Bovidae family. After being cooked and added with ingredients to ferment, it becomes sour due to the action of lactic acid bacteria. Since there are still many miscellaneous bacteria in the raw materials for preparing yogurt, it is necessary to sterilize the raw materials before preparing yogurt. The principle of sterilization is that within a certain temperature range, the lower the temperature, the slower the bacterial reproduction; the higher the temperature, the faster the reproduction. However, if the temperature is too high, the bacteria will die. Different bacteria have different optimal growth temperatures and heat and cold resistance capabilities. Pasteurization actually utilizes the characteristic that pathogens are not very heat-resistant, and by treating with an appropriate temperature and holding time, all of them are killed.

[0003] In the prior art, such as a yogurt pasteurizer disclosed in the patent with the publication number CN208972492U, a protective cover is provided outside the milk bucket. The internal heat insulation layer absorbs the heat outside the milk bucket to prevent workers from being accidentally scalded when touching it, solving the problem that due to heating, the milk filling tank has a metal outer layer with strong heat conduction and is likely to be scalded if not careful. The front end of the milk outlet is connected to a sterilization joint, and the bacteria outside the milk outlet are killed by irradiating with an ultraviolet sterilization lamp. By sterilizing the external joint together, the hygiene is improved, solving the problem that bacteria often breed at the milk outlet and the internal milk source is contaminated during milk outlet, resulting in insufficient hygiene. However, in actual use, although the existing sterilizer can absorb heat through the heat insulation layer, on the one hand, the heat in the milk bucket will be absorbed by the heat insulation layer, causing heat loss, and on the other hand, the temperature of the heat insulation layer itself will also increase after absorbing heat. Therefore, there is still a problem that the heat insulation effect is not thorough enough. Secondly, although the existing sterilizer can also sterilize the milk outlet part through ultraviolet rays, the ultraviolet sterilization lamp is directly arranged on one side of the milk outlet part in an exposed state, unable to irradiate the milk outlet part comprehensively, resulting in an incomplete sterilization effect, and at the same time, the exposure of ultraviolet rays on the outside will cause certain harm to the operator.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, a sterilizer capable of being stable includes a sterilization tank 1, a stirring rod assembly, an ultraviolet sterilization assembly, and a heating spiral tube 8. The stirring rod assembly and the heating spiral tube 8 are both arranged in the sterilization tank 1. The upper end of the sterilization tank 1 is communicated with a feed pipe 4, and the lower end of the sterilization tank 1 is communicated with a discharge pipe 5. The ultraviolet sterilization assembly is connected to the pipe body of the discharge pipe 5. The yogurt raw material to be sterilized can be poured into the sterilization tank 1 through the feed pipe 4, and then the yogurt raw material in the tank can be heated through the heating spiral tube 8 so that the temperature of the yogurt raw material in the tank is within a stable range where bacteria cannot reproduce. The yogurt raw material is stirred through the stirring rod assembly to ensure that the temperature of the yogurt raw material remains consistent, so as to kill the bacteria in the yogurt raw material. And by arranging an ultraviolet sterilization assembly outside the discharge pipe 5, while performing low-temperature sterilization on the yogurt raw material in the tank, the discharge pipe 5 can also be sterilized by ultraviolet rays. Furthermore, when the sterilized yogurt raw material is discharged from the discharge pipe 5, since the discharge pipe 5 is also sterilized, it can be ensured that no miscellaneous bacteria are contacted during the discharge process, so as to ensure a better overall sterilization effect;

[0032] The tank body of the sterilization tank 1 includes an outer tank wall 11 and an inner tank wall 12. There is a heat insulation cavity 13 between the outer tank wall 11 and the inner tank wall 12. A number of heat insulation support seats 7 are connected between the outer tank wall 11 and the inner tank wall 12. By setting the inner and outer walls for the sterilization tank 1, a better heat insulation effect can be achieved. And the inner and outer walls are connected by the heat insulation support seats 7, which can form a stable support for the inner tank wall 12. Furthermore, when the sterilization tank 1 is filled with yogurt raw materials to be sterilized, the stability of the inner tank wall 12 can be maintained to achieve stable sterilization. The ultraviolet sterilization component includes a sterilization outer sleeve 51, a movable sleeve 52, a movable end cover 53 and an ultraviolet sterilization lamp 56. The sterilization outer sleeve 51 is fixedly sleeved on the pipe body of the discharge pipe 5. The movable sleeve 52 is movably inserted into the sterilization outer sleeve 51. The front end of the opening of the movable sleeve 52 is movably connected with the movable end cover 53. A number of ultraviolet sterilization lamps 56 are installed on the inner wall of the front end of the movable sleeve 52. The ultraviolet sterilization lamps 56 are electrically connected to an external power supply through connecting wires. By pulling out the movable sleeve 52 from the sterilization outer sleeve 51 and covering the movable end cover 53 on the front end opening of the movable sleeve 52, the discharge port part of the discharge pipe 5 can be sealed. Then, by starting the ultraviolet sterilization lamps 56, ultraviolet sterilization of the discharge port part of the discharge pipe 5 can be achieved. And through the surrounding ultraviolet sterilization from the outside, a better sterilization effect can be achieved and there will be no leakage of ultraviolet rays to avoid damage to the operators.

[0033] Embodiment 2

[0034] Based on Embodiment 1, the improvement is as follows:

[0035] As Figures 1 to 7 shown, the bottom of the sterilization tank 1 is connected with support feet 14. A bottom plate 2 is arranged below the sterilization tank 1. The sterilization tank 1 is fixedly connected to the bottom plate 2 through the support feet 14, which can form a stable support for the sterilization tank 1 to ensure the stable operation of the sterilizer. And through the arranged support feet 14, the bottom of the sterilization tank 1 can be suspended, so that it is convenient to take out the sterilized yogurt raw materials from the bottom of the sterilization tank 1 via the discharge pipe 5.

[0036] Furthermore, a constant-temperature hot water tank 3 is connected to the bottom plate 2. The constant-temperature hot water tank 3 is located on one side of the sterilization tank 1. One side wall of the constant-temperature hot water tank 3 close to the sterilization tank 1 is communicated with a heating water inlet pipe 31 and a heating water outlet pipe 32. The heating water inlet pipe 31 is communicated at the bottom end of the constant-temperature hot water tank 3, and the heating water outlet pipe 32 is communicated at the upper end of the constant-temperature hot water tank 3. A circulating water pump 33 is installed on the pipe body of the heating water inlet pipe 31. The heating water inlet pipe 31 and the heating water outlet pipe 32 are respectively connected to the two ends of the heating spiral pipe 8. The low-temperature hot water in the constant-temperature hot water tank 3 can be conveyed to the heating spiral pipe 8 through the circulating water pump 33 to realize low-temperature heating of the yogurt raw material in the sterilization tank 1. And the low-temperature hot water flows through the heating spiral pipe 8 and is then conveyed back to the constant-temperature hot water tank 3 through the heating water outlet pipe 32, that is, to realize the circulating flow of the low-temperature hot water, so as to realize continuous constant-temperature low-temperature heating of the yogurt raw material in the sterilization tank 1, which can not only kill the bacteria in the yogurt raw material but also keep the flavor of the nutrients in the yogurt raw material.

[0037] Furthermore, a thermometer 15 and a pressure gauge 16 are connected to the upper end of the sterilization tank 1, and the measuring bottoms of the thermometer 15 and the pressure gauge 16 are inserted into the tank of the sterilization tank 1, so as to be able to measure and monitor the pressure and temperature in the tank in real time during the sterilization process, so that the staff can timely master the sterilization situation in the tank.

[0038] Furthermore, a quick-cooling water inlet pipe 17 and a quick-cooling water outlet pipe 18 are connected to the tank wall of the sterilization tank 1. The quick-cooling water inlet pipe 17 is located at the bottom end of the tank wall of the sterilization tank 1, and the quick-cooling water outlet pipe 18 is located at the upper end of the tank wall of the sterilization tank 1. The quick-cooling water inlet pipe 17 and the quick-cooling water outlet pipe 18 are both communicated with the heat insulation cavity 13, and the quick-cooling water inlet pipe 17 and the quick-cooling water outlet pipe 18 are connected to an external cooling water delivery pipe. After the sterilization is completed, cold water can be introduced into the heat insulation cavity 13 through the quick-cooling water inlet pipe 17. After the heat insulation cavity 13 is filled with cold water, the cold water is output from the quick-cooling water outlet pipe 18, that is, it can realize rapid cooling treatment of the yogurt raw material in the tank. The rapid change of heat and cold can promote the death of bacteria and play a further sterilization effect.

[0039] As Figure 2 、 Figure 3 and Figure 4 shown, a limiting chute 57 is provided on the inner wall of the pipe of the sterilization outer sleeve 51. A limiting slider 58 is connected to the tail end of the outer wall of the movable sleeve 52, and the limiting slider 58 is clamped in the limiting chute 57, which can play a role in limiting the outward extraction of the movable sleeve 52, so as to avoid the separation of the movable sleeve 52 from the sterilization outer sleeve 51 due to excessive outward extraction amplitude.

[0040] Furthermore, a damping shaft 54 ​​is connected to the bottom end of the pipe mouth of the movable sleeve 52, and the movable sleeve 52 is rotatably connected to the edge of the movable end cover 53 through the damping shaft 54. A contact switch 55 is embedded in the upper end of the pipe mouth of the movable sleeve 52, and the contact switch 55 is connected in series to the connecting wire of the ultraviolet germicidal lamp 56. The movable end cover 53 can be rotated to the moving position by the action of the damping shaft 54 ​​to keep the movable end cover 53 fixed, so that the movable end cover 53 can be freely rotated to block the port of the movable sleeve 52, and when the movable end cover 53 blocks the port of the movable sleeve 52, The contact switch 55 can be touched to light up the ultraviolet sterilization lamp 56, and when the movable end cover 53 is unscrewed from the end of the movable sleeve 52, the contact switch 55 is not touched, and the ultraviolet sterilization lamp 56 is extinguished at this time, which ensures that the ultraviolet sterilization of the pipe opening of the discharge pipe 5 can only be performed when the movable sleeve 52 is pulled out and the movable cover plate 53 is combined with the movable sleeve 52 to form a closed cover state for the pipe opening of the discharge pipe 5 from the outside, which ensures that when the yogurt raw materials that have been sterilized in the sterilization tank 1 are discharged from the pipe opening of the discharge pipe 5, they will not contact with miscellaneous bacteria and cause contamination of the yogurt raw materials.

[0041] If Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown in FIG. 1 , the stirring rod assembly includes a stirring rod 61, an outer ring lever 62 and an inner ring lever 63. The outer ring lever 62 and the inner ring lever 63 are symmetrically connected to the bottom end of the stirring rod 61. The outer ring lever 62 is arranged on the outer side of the spiral of the heating spiral tube 8, and the inner ring lever 63 is arranged on the inner side of the spiral of the heating spiral tube 8. The inner and outer rings of the yogurt raw materials in the tank can be stirred, thereby improving the stirring effect of the yogurt raw materials and improving the efficiency of uniform temperature mixing of the yogurt raw materials.

[0042] Furthermore, the outer ring lever 62 and the inner ring lever 63 are both connected to an inclined stirring plate 64, and the inclined stirring plates 64 connected to the rods of the two outer ring levers 62 and the two inner ring levers 63 are inclined in opposite directions. The upper end of the sterilizing tank 1 is fixedly connected to a stirring motor 6, and the stirring rod 61 is coaxially connected to the rotating shaft of the stirring motor 6. The stirring motor 6 can provide driving force, thereby driving the outer ring lever 62 and the inner ring lever 63 to rotate in the sterilizing tank 1. While rotating, the inclined stirring plates 64 can exert an upward or downward force on the yogurt raw materials according to different inclination directions, which can further enhance the stirring and mixing effect of the yogurt raw materials.

[0043] ​​Furthermore, the heat-insulating support base 7 includes a heat-insulating rubber block 71 and a docking support block 73. The docking support blocks 73 are respectively connected to both ends of the heat-insulating rubber block 71. Dovetail-shaped clamping blocks 72 are integrally connected to both ends of the heat-insulating rubber block 71. Dovetail-shaped clamping grooves 74 are formed in the docking support blocks 73, and the dovetail-shaped clamping blocks 72 are placed in the dovetail-shaped clamping grooves 74. The heat-insulating rubber block 71 and the docking support block 73 can be firmly connected together through the clamping effect of the dovetail grooves. Moreover, the provided heat-insulating rubber block 71 can play a heat-insulating role to avoid heat transfer, thereby preventing the temperature of the outer wall 11 of the tank from rising.

[0044] Working principle: Pour the yogurt raw material to be sterilized into the sterilization tank 1 through the feed pipe 4, and then heat the yogurt raw material in the tank through the heating spiral pipe 8 to make the temperature of the yogurt raw material in the tank within a stable range where bacteria cannot reproduce. Stir the yogurt raw material through the stirring rod assembly to ensure that the temperature of the yogurt raw material remains consistent, so as to achieve the killing of bacteria in the yogurt raw material. Moreover, by providing an ultraviolet sterilization assembly outside the discharge pipe 5, while performing low-temperature sterilization on the yogurt raw material in the tank, the discharge pipe 5 can also be sterilized by ultraviolet rays. After the movable end cover 53 is rotated to the moving position through the action of the damping rotating shaft 54, the movable end cover 53 can be fixed. Furthermore, the movable end cover 53 can be freely rotated to block the port of the movable sleeve 52. When the movable end cover 53 blocks the port of the movable sleeve 52, it can touch the contact switch 55 to turn on the ultraviolet sterilization lamp 56. When the movable end cover 53 is screwed out from the port of the movable sleeve 52, the contact switch 55 is not touched, and at this time the ultraviolet sterilization lamp 56 goes out. It can be ensured that the discharge pipe 5 can only be sterilized by ultraviolet rays when it is completely blocked, so as to ensure that when the sterilized yogurt raw material is discharged from the discharge pipe 5, since the discharge pipe 5 is also sterilized, it can be ensured that no miscellaneous bacteria are contacted during the discharge process, so as to ensure a better overall sterilization effect.
