[0002] Bread and cakes require sterilization during their production process. High-temperature sterilization generally works by destroying proteins, nucleic acids, and active substances within cells, thereby disrupting cellular activity, disrupting bacterial biosynthesis, and ultimately killing bacteria. High-temperature sterilization can be categorized into two types: moist heat and dry heat. Moist heat sterilization uses high-temperature steam, while dry heat sterilization methods include dry baking, infrared sterilization, microwave sterilization, and incineration.

[0003] In the prior art, when high-temperature steam is used to sterilize bread and cake foods, uneven contact between the high-temperature steam and the bread and cake foods often occurs, which may cause poor sterilization effects on certain parts of the bread and cake foods. Moreover, the high-temperature steam after sterilization is mostly discharged directly. Since the high-temperature steam also contains a large amount of heat, the heat utilization rate of the high-temperature steam is poor. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a bread and cake food sterilization equipment, comprising a sterilization box 1 and a box door 2, the box door 2 covering the front end of the sterilization box 1, a plurality of electric heating rods 20 are installed at the bottom end of the sterilization box 1, and a mesh bottom plate 4 is fixed at the lower end of the sterilization box 1, a shaft tube 9 is rotated through the middle of the mesh bottom plate 4, and a plurality of concave sterilization tubes 10 are connected on both sides of the shaft tube 9, and a plurality of nozzles 12 and an infrared sterilization lamp 11 are connected to the inner side and upper end of the concave sterilization tube 10, and a mesh support plate 5 fixed to the inner side wall of the sterilization box 1 is provided below the concave sterilization tube 10, a support frame 13 is fixed to the middle of the upper end of the sterilization box 1, and a rotary drive assembly is provided above the shaft tube 9.

[0023] When the sterilization equipment is used to sterilize bread and cake foods at high temperature, the bread and cake foods are placed on the mesh support plate 5, the box door 2 is closed, and water is stored at the bottom of the sterilization box 1. After the water at the bottom of the sterilization box 1 is heated by the electric heating rod 20, a part of the steam rises through the mesh bottom plate 4 and the mesh holes of the mesh support plate 5, and then comes into contact with the bread and cake foods, achieving the effect of preliminary high-temperature sterilization.

[0024] In this embodiment, the rotary drive assembly includes a motor 14 and a rotating shaft 15. The motor 14 is fixed to the top end of the support frame 13. One end of the rotating shaft 15 is connected to the power end of the motor 14, and the rotating shaft 15 rotates and passes through the sterilization box 1. The upper end of the shaft tube 9 is fixed to the other end of the rotating shaft 15. The lower end of the shaft tube 9 is connected to the air collecting hood 6. A mesh grille 7 is fixed in the air collecting hood 6, and an exhaust fan 8 is installed on the mesh grille 7.

[0025] And start the exhaust fan 8 in the air collecting hood 6, and the exhaust fan 8 draws another part of the high-temperature steam into the shaft tube 9, the concave sterilization tube 10 and the nozzle 12 through the air collecting hood 6. In the process of the nozzle 12 spraying the high-temperature steam onto the bread and cake food, the motor 14 works and drives the rotating shaft 15, the shaft tube 9, the concave sterilization tube 10 and the nozzle 12 to rotate at a uniform speed, thereby facilitating the uniform and comprehensive high-temperature sterilization of the bread and cake food through the nozzle 12. Since the infrared sterilization lamp 11 will rotate with the concave sterilization tube 10, the infrared sterilization lamp 11 is combined with the infrared sterilization lamp 11 to perform infrared sterilization on the bread and cake food, thereby better improving the sterilization effect of the bread and cake food.

[0026] In this embodiment, both sides of the upper end of the sterilization box 1 are connected to the exhaust pipe 3, and the exhaust pipe 3 is provided with a serpentine heat exchange tube 18. The left and right sides of the sterilization box 1 are connected to the water inlet valve 21 close to the bottom of the mesh bottom plate 4, and the water inlet of the water inlet valve 21 is connected to the water outlet pipe 19 extending upward. The upper end of the support frame 13 is fixed with a water pump 16, and the water outlet of the water pump 16 is connected to two water pipes 17 distributed on the left and right. One end of the serpentine heat exchange tube 18 passes through the outside of the exhaust pipe 3, and one end of the serpentine heat exchange tube 18 is connected to the adjacent water pipe 17, and the other end of the serpentine heat exchange tube 18 passes through the outside of the exhaust pipe 3, and the other end of the serpentine heat exchange tube 18 is connected to the water outlet pipe 19.

[0027] When high-temperature steam is discharged into the exhaust pipe 3, the water pump 16 is started and the cold water is discharged into the serpentine heat exchange tube 18 through the water pipe 17 under the premise of connecting the water pump 16 to the external water source. The high-temperature steam in the exhaust pipe 3 heats the cold water in the serpentine heat exchange tube 18, and the heated water is then discharged into the bottom of the sterilization box 1 through the outlet pipe 19 and the water inlet valve 21 for reuse. This not only improves the efficiency of heating the bottom water in the sterilization box 1 to generate steam, but also helps to reduce the waste of high-temperature steam heat.

[0028] In this embodiment, a filter screen 24 is installed at the upper end of the exhaust pipe 3.

[0029] By installing a filter 24 in the exhaust pipe 3, it is not only beneficial to prevent external debris from entering the sterilization box 1 through the exhaust pipe 3, but also beneficial to slow down the speed of steam being discharged from the exhaust pipe 3, which helps to make the high-temperature steam better heat the cold water in the serpentine heat exchange tube 18 and better reduce the loss of high-temperature heat.

[0030] In this embodiment, the lower end of the outer side of the water outlet pipe 19 is connected to a water outlet valve 23 , and the lower left end of the sterilization box 1 is connected to a waste water valve 22 .

[0031] When there is no need to heat the water in the serpentine heat exchange tube 18 in the sterilization box 1, close the water inlet valve 21, open the water outlet valve 23, and place a container filled with hot water under the water outlet valve 23. The heated water in the serpentine heat exchange tube 18 is discharged through the water outlet valve 23 for use. When the waste water in the sterilization box 1 needs to be discharged, the waste water valve 22 can be opened to discharge it, so as to facilitate the water change operation in the sterilization box 1.

[0032] Working principle:

[0033] When the sterilization equipment is used to sterilize bread and cake foods at high temperature, the water at the bottom of the sterilization box 1 is heated by the electric heating rod 20, and a part of the steam rises through the mesh holes of the mesh bottom plate 4 and the mesh support plate 5, and then comes into contact with the bread and cake foods, and the exhaust fan 8 in the air collecting hood 6 is started. The exhaust fan 8 draws another part of the high-temperature steam into the shaft tube 9, the concave sterilization tube 10 and the nozzle 12 through the air collecting hood 6. In the process of the nozzle 12 spraying the high-temperature steam onto the bread and cake foods, the motor 14 works and drives the rotating shaft 15, the shaft tube 9, the concave sterilization tube 10 and the nozzle 12 to rotate at a uniform speed, which is conducive to the uniform and comprehensive high-temperature sterilization of the bread and cake foods through the nozzle 12. Since the infrared sterilization lamp 11 will rotate with the concave sterilization tube 10, the infrared sterilization lamp 11 is combined with the infrared sterilization lamp 11 to perform infrared sterilization on the bread and cake foods.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
