Description

Technical Field

[0001] The invention relates to the field of frozen food sterilization, in particular to a sterilization device for frozen food production. Background Art

[0002] Frozen food refers to a type of food that is made by rapidly freezing fresh food at extremely low temperatures through the use of rapid freezing technology in order to preserve its nutritional content and flavor. Frozen food is divided into cooled food and frozen food. Frozen food is easy to preserve and is widely used in the production, transportation and storage of perishable foods such as meat, poultry, aquatic products, milk, eggs, vegetables and fruits. Frozen food is usually pre-treated during the processing process, such as blanching and blanching, to maintain its nutritional content and color. Frozen food requires strict control of sanitary conditions during the production process to avoid microbial contamination. Therefore, it is necessary to sterilize frozen food during the production process. Frozen food is sterilized by a sterilization device. When sterilizing frozen food, on the one hand, the packaging of the frozen food needs to be sterilized, and on the other hand, the frozen food itself needs to be sterilized. When sterilizing the frozen food itself, in order to prevent harmful substances from being mixed into the frozen food, the frozen food is generally sterilized by ultraviolet sterilization equipment.

[0003] Ultraviolet sterilization equipment uses the radiation intensity of ultraviolet lamps, that is, the radiation intensity emitted by ultraviolet sterilization lamps. The ultraviolet rays in the UVC band are emitted by ultraviolet sterilization lamps to destroy the DNA and RNA structure of microorganisms, causing them to lose their reproductive ability or die directly. Ultraviolet rays can effectively kill almost all bacteria and viruses, including some parasites that are extremely harmful to humans. Moreover, only ultraviolet sterilization equipment needs to add any chemicals during use, so it will not cause residual substances harmful to the human body in frozen foods.

[0004] However, the sterilization effect of ultraviolet sterilization equipment is affected by many factors. First of all, ultraviolet sterilization equipment is a normal temperature sterilization equipment, so it will be affected by the temperature and humidity of the environment. In a low temperature environment, the resistance of bacteria increases and the sterilization effect of ultraviolet rays is weakened. When the humidity of the environment is too high, the water molecules in the air will absorb ultraviolet rays, thereby reducing the penetration of ultraviolet rays and the disinfection effect, resulting in a significant decrease in the sterilization efficiency of ultraviolet rays. Secondly, during the production process of frozen foods, the food needs to be cleaned, and a large amount of water will adhere to the surface of the food after cleaning. The attached water will also absorb ultraviolet rays, resulting in a decrease in the sterilization efficiency of ultraviolet rays. Based on the above problems, the present application proposes a sterilization device for frozen food production. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a sterilization device for frozen food production.

[0036] In a typical implementation of the present application, Figure 1-5 As shown, a sterilization device for frozen food production includes:

[0037] Sterilization box 1, a controller 6 is fixedly arranged on the front side of the sterilization box 1;

[0038] The ultraviolet sterilization component 2 is installed inside the sterilization box 1 and is used to sterilize frozen food. The ultraviolet sterilization component 2 includes an electric push rod 21 fixedly arranged on the top of the sterilization box 1. An upper mounting plate 22 is fixedly arranged at the output end of the electric push rod 21. A lower mounting plate 23 is arranged below the upper mounting plate 22. A U-shaped connecting rod 24 is connected between the lower mounting plate 23 and the upper mounting plate 22. The number of the U-shaped connecting rods 24 is four, and the four U-shaped connecting rods 24 are symmetrically distributed. The front and rear side walls of the sterilization box 1 are both provided with sliding grooves for the sliding of the U-shaped connecting rods 24. The height of the U-shaped connecting rods 24 is less than the height of the sliding groove. Four U-shaped connecting rods 24 are installed on the lower mounting plate 23 and the upper mounting plate 22. The U-shaped connecting rod 24 makes the lower mounting plate 23 and the upper mounting plate 22 fall and rise at a constant distance, and the sliding groove can limit the position of the U-shaped connecting rod 24. The bottom of the lower mounting plate 23 and the upper mounting plate 22 are fixedly provided with an ultraviolet sterilization lamp 25. The electric push rod 21 pushes the upper mounting plate 22 to move downward, and the upper mounting plate 22 drives the lower mounting plate 23 to move downward through the U-shaped connecting rod 24, thereby reducing the distance between the ultraviolet sterilization lamp 25 and the food. The disinfection effect of the ultraviolet sterilization lamp 25 is closely related to the distance. The closer the frozen food is to the ultraviolet sterilization lamp 25, the stronger the disinfection effect is. Therefore, when the temperature is low or the humidity is high, the sterilization effect of the ultraviolet sterilization lamp 25 on the frozen food can be guaranteed.

[0039] The attached water drop cleaning component 3 is fixedly installed on the left side of the sterilization box 1, and is used to scrape off and absorb the water attached to the surface of the frozen food.

A rectangular plate 36 is fixedly arranged between the facing surfaces of the transmission chain 35. A cotton cleaning brush 37 is fixedly arranged on the side of the rectangular plate 36 away from the rotating shaft 33. The driving motor 32 drives the rotating shaft 33 on the left side to drive the rotating sprocket 34 to rotate. The rotating sprocket 34 on the left side drives the rotating sprocket 34 on the right side to rotate through the transmission chain 35, so that the transmission chain 35 drives the cotton cleaning brush 37 to move through the rectangular plate 36. When the cotton cleaning brush 37 contacts the cleaned food, the cotton cleaning brush 37 absorbs the water droplets attached to the surface of the food, and can remove the water droplets attached to the surface of the frozen food during cleaning, thereby avoiding the water droplets on the surface of the frozen food, avoiding the water droplets on the surface of the frozen food from refracting the ultraviolet light and reducing the amount of ultraviolet light exposure, and avoiding the water droplets on the surface of the frozen food from absorbing part of the ultraviolet light, thereby ensuring the sterilization effect of ultraviolet light on the frozen food;

[0040] The moisture drying component 4 is fixedly installed on the top of the sterilization box 1, and is used to dry the frozen food and the cotton cleaning brush 37, so as to facilitate the drying of the cotton cleaning brush 37 that absorbs water droplets, and ensure the absorption effect of the cotton cleaning brush 37 on the water droplets on the surface of the frozen food. Secondly, the frozen food after the water is discharged can be dried, and the moisture on the surface of the frozen food can be further reduced;

[0041] The food conveying component 5 is fixedly installed inside the sterilization box 1 and is used for conveying frozen food. The cleaned frozen food can be conveyed and the frozen food can be turned over, so that the frozen food can be fully sterilized.

An L-shaped connecting rod 455 is fixedly provided on the right side of the rectangular air outlet pipe 454. The L-shaped connecting rod 455 is fixedly installed on the U-shaped connecting rod 24. The air is drawn into the air filter box 41 through the fan 42, and the moisture and dust in the air are removed through the activated carbon filter 43. The filtered air enters the air outlet duct 1 441 and the air outlet duct 2 451 through the three-way joint. The air entering the air outlet duct 1 441 will enter the air heating box 442, be heated by the heating rod 443, and enter the installation frame 31 through the hot air outlet pipe 444, so as to dry the cotton cleaning brush 37. The moisture after drying can be discharged through the left side of the installation frame 31. At the same time, the air entering the air outlet duct 2 451 will enter the air outlet cover 452, and then enter the rectangular air outlet pipe 454, and be discharged onto the frozen food through the air outlet.

[0043] As a preferred implementation in this embodiment, refer to Fig.10The food conveying component 5 includes a lower conveyor belt 51 fixedly installed on the lower side wall of the sterilization box 1, a mounting vertical plate 52 is fixedly arranged on the top of the lower conveyor belt 51, and an upper conveyor belt 53 is fixedly arranged on the top of the mounting vertical plate 52. The distance between the lower conveyor belt 51 and the lower mounting plate 23 is the same as the distance between the upper conveyor belt 53 and the upper mounting plate 22. The thickness of the upper mounting plate 22 and the lower mounting plate 23 are the same, so as to ensure that the distance between the upper mounting plate 22 and the lower mounting plate 23 and the frozen food is always the same, so that the distance between the upper and lower ultraviolet sterilization lamps 25 and the frozen food is the same, so that the upper and lower ultraviolet sterilization lamps 25 after adjustment have the same sterilization effect on the frozen food, and the lower conveyor belt 51 is fixedly installed on the top of the lower conveyor belt 51. An arc plate 1 54 is fixedly provided on the right side of the conveyor belt 51, and an outer conveying roller 55 is rotatably provided inside the arc plate 1 54. An arc plate 2 56 is fixedly provided on the right side of the upper conveyor belt 53, and an inner conveying roller 57 is rotatably provided inside the arc plate 2 56. The upper conveyor belt 53 can push the cleaned frozen food for transportation, and when the food is transported to the right side, it will enter the inner conveying roller 57 and slide downward through the inner conveying roller 57. The food will fall onto the outer conveying roller 55 under the action of its own weight, so that the food can be turned over. The turned over food slides to the lower conveyor belt 51 through the outer conveying roller 55, and the food is moved out of the sterilization box 1 through the lower conveyor belt 51.

[0044] In this embodiment,

[0045] Working principle of the present invention: When in use, the cleaned frozen food is placed on the upper conveyor belt 53, and the upper conveyor belt 53 conveys the food to the right. At the same time, the output end of the driving motor 32 drives the rotating shaft 33 to rotate, and the rotating sprocket 34 is driven to rotate through the rotating shaft 33. The rotating sprocket 34 on the left side drives the rotating sprocket 34 on the right side to rotate through the transmission chain 35, so that the transmission chain 35 drives the rectangular plate 36 to move, and drives the cotton cleaning brush 37 to move through the rectangular plate 36. When the cotton cleaning brush 37 contacts the cleaned food, the cotton cleaning brush 37 absorbs the water drops attached to the surface of the food. Then the cleaned food enters the sterilization box 1, and is irradiated and sterilized by the ultraviolet sterilization lamp 25 at the bottom of the upper mounting plate 22, and enters the surface of the inner conveying roller 57 under the conveyance of the upper conveyor belt 53, and slides downward through the inner conveying roller 57. After the food slides to a certain distance on the inner conveying roller 57, it falls onto the outer conveying roller 55 under its own weight, and slides onto the lower conveyor belt 51 through the outer conveying roller 55. At this time, the top and bottom positions of the food are interchanged, and the food is sterilized by the ultraviolet sterilization lamp 25 at the bottom of the lower mounting plate 23.

[0046] When the cotton cleaning brush 37 absorbs the water droplets attached to the surface of the food, the external air is sucked into the air filter box 41 through the fan 42, and the air is filtered through the activated carbon filter 43 to remove the moisture and dust in the air, and then enters the inside of the three-way joint. At this time, the air outlet hole at the bottom of the rectangular air outlet pipe 454 is blocked by the blocking frame 453, so that the air enters the inside of the air outlet duct 1 441 through the three-way joint, and enters the inside of the air heating box 442 through the air outlet duct 1 441, and heats the air through the heating rod 443. The heated air enters the installation frame 31 through the hot air outlet pipe 444, and the cotton cleaning brush 37 that absorbs moisture is dried by the hot air that enters;

[0047] When the temperature of the external environment is low or the humidity is high, the controller 6 is used to control the conveying speed of the lower conveyor belt 51 and the upper conveyor belt 53 to decrease, thereby increasing the illumination time of the food by the ultraviolet sterilization lamp 25, and the upper mounting plate 22 is pushed downward by the output end of the electric push rod 21, and the upper mounting plate 22 drives the lower mounting plate 23 to move downward through the U-shaped connecting rod 24, so that the upper mounting plate 22 and the lower mounting plate 23 simultaneously drive the ultraviolet sterilization lamp 25 to move downward, thereby reducing the distance between the ultraviolet sterilization lamp 25 and the food;

[0048] When the U-shaped connecting rod 24 moves downward, the U-shaped connecting rod 24 drives the rectangular air outlet pipe 454 to move downward through the L-shaped connecting rod 455, so that the bottom end of the blocking frame 453 moves out from the air outlet hole at the bottom of the rectangular air outlet pipe 454. At this time, the dry air filtered by the activated carbon filter 43 enters the air outlet duct 1 441 and the air outlet duct 2 451 through the three-way joint. The dry air entering the air outlet duct 2 451 enters the air outlet cover 452, enters the rectangular air outlet pipe 454 through the air outlet cover 452, and is discharged through the air outlet hole at the bottom of the rectangular air outlet pipe 454. The vertically arranged rectangular air outlet pipe 454 allows the dry air to be sprayed on the surface of the food to dry the surface of the food.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
