Description

Technical Field

[0001] The present invention relates to the technical field of fruit sterilization, and specifically relates to an oxygen removal and sterilization device for raw materials used in fruit freeze-drying processing. Background Art

[0002] Vacuum freeze-dried food is also called FD food. Due to this special freeze-drying process, it can maximize the retention of the color, aroma, taste, nutritional components, appearance shape, etc. of the original fresh food. Among them, it is more convenient to make freeze-dried strawberries, and no processes such as slicing are required.

[0003] A disinfection and sterilization device for fruit food processing disclosed in Patent No. CN213029675U includes a bottom plate. Above the bottom plate, a sterilization cylinder is installed. On the surface of the inner wall of the sterilization cylinder, a multi-purpose pipe is installed. Above the sterilization cylinder, a funnel is installed. Below the funnel, an airtight valve is installed. On one side of the funnel, a motor is installed. When in use, start the ozone generator. The ozone generator sends ozone into the multi-purpose pipe through the air supply pipe and discharges it through the multi-purpose pipe to perform ozone sterilization on the fruit. Start the motor. The output end of the motor drives the stirring blades to rotate through the rotating shaft, thereby agitating the fruit in the sterilization cylinder to make it fully contact with ozone, so as to improve the sterilization effect. When the fruit falls into the disinfection box, start the ultraviolet disinfection device to further disinfect and sterilize the fruit, completely removing harmful substances such as bacteria on the surface of the fruit to avoid affecting subsequent processing.

[0004] In the prior art, during the planting process of fruits, their surfaces will contain impurities such as soil. In the cleaning and sterilization work, first, these residual impurities on the surface need to be cleaned and removed. However, after cleaning, due to the pitted surface of strawberries, some soil will still remain on their surfaces. These soils will enter the sterilization liquid with the strawberries, thereby contaminating the sterilization liquid and affecting subsequent sterilization. At the same time, after oxygen removal and sterilization of strawberries, manual picking is still required to classify different sizes. However, after long-term picking, it will cause fatigue of the staff, thereby reducing the sorting efficiency. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 - 8As shown in the figure, the present application provides a raw material deoxidation and sterilization device for fruit freeze-drying processing, including a cleaning bin 1, and further including:

[0039] A pressing cylinder 14, rotatably arranged in the cleaning bin 1, for cleaning strawberries;

[0040] A rinsing mechanism 2, arranged above the cleaning bin 1, for rinsing strawberries;

[0041] A sterilization mechanism 3, arranged on one side of the cleaning bin 1, for sterilizing strawberries;

[0042] A freezing bin 4, arranged on one side of the sterilization mechanism 3, for quickly freezing strawberries;

[0043] A sorting mechanism 5, connected to the freezing bin 4, for sorting strawberries;

[0044] A water outlet 6, arranged in the cleaning bin 1, for cleaning strawberries.

[0045] During operation, in the prior art, during the planting process of fruits, their surfaces will contain impurities such as soil. In the cleaning and sterilization work, first, these residual impurities on the surface need to be cleaned and removed. However, after cleaning, due to the uneven surface of strawberries, some soil will still remain on their surfaces. These soils will enter the sterilization liquid with the strawberries, thus contaminating the sterilization liquid and affecting subsequent sterilization. At the same time, after deoxidation and sterilization, strawberries still need to be manually sorted to classify different sizes. However, after long-term sorting, it will cause fatigue of the staff, thus reducing the sorting efficiency. To prevent such events from occurring, first, pour clean water into the cleaning bin 1, and then pour the picked strawberries into the cleaning bin 1. After pouring, turn on the water outlet 6. The water outlet 6 can extract the water in the cleaning bin 1 and spray it out from the water outlet head to form an inertial water flow, driving the strawberries to the pressing cylinder 14. Subsequently, the strawberries are pressed below the water surface by the pressing cylinder 14 for cleaning. After cleaning, they reach the rinsing mechanism 2, and the residual impurities on the surface of the strawberries are washed away by the rinsing mechanism 2. After rinsing, they are transported to the sterilization mechanism 3 for deoxidation and sterilization work, and finally reach the freezing bin 4 for rapid freezing to facilitate subsequent production of freeze-dried products. After freezing, the strawberries reach the sorting mechanism 5, and the strawberries of different sizes are sorted, and finally collected.

[0047] During operation, the cleaning chamber 1 is divided into two areas. One area is the cleaning area 11, and the other area is the discharging area 12. The cleaning area 11 contains cleaning water, and the discharging area 12 is blocked by a baffle to separate the cleaning water. First, the strawberries are poured into the cleaning area 11 in the cleaning chamber 1. Subsequently, the rotating shaft 13 is driven to rotate. When the rotating shaft 13 rotates, it drives the sleeved pressing cylinder 14 to rotate. A plurality of pressing plates 141 are fixedly connected to the pressing cylinder 14. When the pressing plates 141 rotate, they will drive the water flow to flow. During the flowing process of the water flow, it will drive the strawberries to flow towards the pressing cylinder 14. When reaching the pressing cylinder 14, the pressing plates 141 on the pressing cylinder 14 will press some strawberries below the water surface and make them contact with the cleaning roller 15 at the bottom. The cleaning roller 15 is provided with bristles, and when contacting, it will clean the soil and impurities on the strawberries. Under the continuous rotation of the pressing cylinder 14, it will drive the strawberries to reach the cleaning belt 17 and lose the downward pressure of the pressing plates 141. The strawberries will float to the water surface again. After floating to the water surface, the strawberries will reach the cleaning belt 17 through the flowing of the water flow. Driven by the cleaning belt 17, the strawberries are moved away from the water surface. When the strawberries are away from the water surface and reach below the flushing chamber 21, the flusher 25 and the flushing head 26 at the bottom of the chamber are started to flush the strawberries. The water in the flushing chamber 21 is conveyed by the water delivery pipe 211. The other end of the water delivery pipe 211 is connected to the cleaning chamber 1. After the water in the cleaning chamber 1 is pumped into the flushing chamber 21 by the water delivery pipe 211, it is filtered by the filter plate 22 in the flushing chamber 21. Since the cleaning chamber 1 is used to clean strawberries, the water in the cleaning chamber 1 will contain impurities such as soil. After being filtered by the filter plate 22, it is then conveyed to the lower flusher 25. During the transmission, the external driving gear 171 is driven to rotate by the cleaning belt 17, and then the bidirectional lead screw 23 in the flushing chamber 21 is driven to rotate through the transmission belt 213 and the transmission gear 212, so as to drive the cleaning brush 241 to move back and forth on the filter plate 22, and clean the soil and other impurities intercepted on the filter plate 22 to the two side openings. The openings can be connected to waste collection equipment for collecting waste. The rinsed strawberries are conveyed by the cleaning belt 17 to the sterilization mechanism 3 for sterilization work.

[0048] As Figure 3 shown, a notch 121 is formed in the side wall of the cleaning chamber 1; the notch 121 is located in the discharging area 12; a telescopic spring 1211 is fixedly connected to the bottom of the notch 121; one end of the telescopic spring 1211 away from the notch 121 is fixedly connected to a slider 1212; the slider 1212 is slidably arranged in the notch 121; an elastic plate 18 is fixedly connected to the side wall of the slider 1212; the elastic plate 18 is hinged to the side wall of the cleaning chamber 1; a discharging belt 1213 is rotatably connected to the side wall of the cleaning chamber 1; the discharging belt 1213 is arranged below the elastic plate 18;

[0049] During operation, a spring plate 18 is arranged below the cleaning belt 17. After the strawberries are cleaned, they will fall onto the spring plate 18. When falling onto the spring plate 18, they will squeeze the telescopic springs 1211 on both sides. Due to the setting of the telescopic springs 1211, the falling of the strawberries can be alleviated, thus protecting the strawberries from being smashed. Moreover, the spring plate 18 is made of rubber material. After the strawberries reach the spring plate 18, they will slide onto the discharge belt 1213 again. The strawberries are conveyed to the sterilization mechanism 3 by the discharge belt 1213 for sterilization and deoxidation work.

[0050] As Figure 3 shown, the sterilization mechanism 3 includes a sterilization chamber 31; the sterilization chamber 31 is arranged below the discharge belt 1213; a sterilization belt 32 is rotatably arranged in the sterilization chamber 31; a bridge plate 311 is fixedly connected to the side wall of the sterilization chamber 31; a deoxidation chamber 33 is fixedly connected to the bridge plate 311; a diversion plate 312 is fixedly connected to the side wall of the sterilization chamber 31;

[0051] During operation, the sterilization chamber 31 contains sterilization water. After the strawberries reach the sterilization chamber 31, they will be soaked in the sterilization water. During the soaking process, they will be slowly conveyed to below the deoxidation chamber 33 by the sterilization belt 32, and the deoxidation work will be carried out by the deoxidation chamber 33, and then conveyed to the diversion plate 312. There are many obstacles on the diversion plate 312, and these obstacles can make the strawberries flow separately, avoiding the large-scale influx of strawberries into the freezing chamber 4.

[0052] As Figure 3 shown, the freezing chamber 4 is fixedly connected to the diversion plate 312; a discharge plate 41 is fixedly connected to the side wall of the freezing chamber 4;

[0053] During operation, the sterilized strawberries reach the freezing chamber 4 for rapid freezing. After freezing, they reach the sorting mechanism 5 through the discharge plate 41 for sorting work.

[0054] As Figures 6 - 8 shown, the sorting mechanism 5 includes a sorting chamber 51; a driving roller 52 is rotatably connected in the sorting chamber 51; a driving belt 53 is fixedly connected to the driving roller 52; multiple groups of driving belts 53 are provided and are equally spaced; a bottom shaft 54 is fixedly connected to the side wall of the sorting chamber 51; the bottom shaft 54 is arranged below the driving belt 53; a stopper 541 is fixedly connected to the bottom shaft 54;

[0055] During operation, after the strawberries reach the sorting bin 51 through the discharge plate 41, they will be supported by the driving belts 53 in the sorting bin 51. There are multiple groups of driving belts 53, and the spacing of each group is the same. The strawberries slide to the middle gap between two groups of driving belts 53. Subsequently, the driving roller 52 is rotated. When rotating, it will drive the driving belts 53 to rotate, thereby driving the strawberries to move horizontally. During the movement, the strawberries will vibrate along with the vibration of the driving belts 53. The strawberries larger than the gap between the driving belts 53 will be supported by the driving belts 53, while the smaller ones will fall into the sorting bin 51. At the same time, when the driving belts 53 move, they will drive the strawberries to the bottom shaft 54. The strawberries will be lifted by the baffle on the bottom shaft 54 to prevent some strawberries from getting stuck between the driving belts 53 and affecting the sorting work.

[0056] As Figure 1 shown, a collection drawer 55 is slidably connected inside the sorting bin 51;

[0057] During operation, the smaller strawberries will reach the collection drawer 55 for collection.

[0058] As Figure 3 shown, a cleaning plate 16 is fixedly connected to the side wall of the cleaning bin 1; there are two groups of cleaning plates 16, both of which are arranged on both sides of the cleaning roller 15;

[0059] During operation, the cleaning plates 16 are arranged on both sides of the cleaning roller 15. When the cleaning roller 15 rotates, it will contact the cleaning plates 16, thereby using the cleaning plates 16 to remove the impurities on the cleaning roller 15, thus facilitating the cleaning of the strawberries.

[0060] Working principle of the present invention: The cleaning bin 1 is divided into two areas, one is the cleaning area 11 and the other is the discharging area 12. The cleaning area 11 contains cleaning water, and the discharging area 12 is blocked by a baffle to separate the cleaning water. First, pour strawberries into the cleaning area 11 in the cleaning bin 1, and then drive the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the sleeved pressing cylinder 14 to rotate. A plurality of pressing plates 141 are fixedly connected to the pressing cylinder 14. When the pressing plates 141 rotate, they will drive the water flow to flow. During the flowing process of the water flow, it will drive the strawberries to flow towards the pressing cylinder 14. When reaching the pressing cylinder 14, the pressing plates 141 on the pressing cylinder 14 will press some strawberries below the water surface and make them contact with the cleaning roller 15 at the bottom. The cleaning roller 15 is provided with bristles, and when contacting, it will clean the soil and impurities on the strawberries. Under the continuous rotation of the pressing cylinder 14, it will drive the strawberries to reach the cleaning belt 17 and lose the downward pressure of the pressing plates 141. The strawberries will float to the water surface again. After floating to the water surface, the strawberries will reach the cleaning belt 17 through the flowing of the water flow. Driven by the cleaning belt 17, the strawberries are driven away from the water surface. When the strawberries are away from the water surface and reach below the flushing bin 21, start the flushing device 25 and the flushing head 26 at the bottom of the bin to flush the strawberries. The water in the flushing bin 21 is conveyed by the water delivery pipe 211. The other end of the water delivery pipe 211 is connected to the cleaning bin 1. After the water in the cleaning bin 1 is pumped into the flushing bin 21 by the water delivery pipe 211, it is filtered by the filter plate 22 in the flushing bin 21. Since the cleaning bin 1 is used to clean strawberries, the water in the cleaning bin 1 will contain impurities such as soil. After being filtered by the filter plate 22, it is then conveyed to the lower flushing device 25. During the transmission, the external driving gear 171 is driven to rotate by the cleaning belt 17, and then the two-way lead screw 23 in the flushing bin 21 is driven to rotate through the transmission belt 213 and the transmission gear 212, so as to drive the cleaning brush 241 to move back and forth on the filter plate 22, and clean the soil and other impurities intercepted on the filter plate 22 to the two side openings. The openings can be connected to waste collection equipment for collecting waste. The rinsed strawberries are conveyed by the cleaning belt 17 to the sterilization mechanism 3 for sterilization work.

[0061] Among them, after the strawberries reach the sorting bin 51 through the discharging plate 41, they will be supported by the driving belts 53 in the sorting bin 51. A plurality of driving belts 53 are provided, and the spacing of each group is the same. The strawberries slide into the middle gap between two groups of driving belts 53. Then drive the driving roller 52 to rotate. When rotating, it will drive the driving belts 53 to rotate, thereby driving the strawberries to move horizontally. During the movement, the strawberries will vibrate with the vibration of the driving belts 53. The strawberries larger than the gap between the driving belts 53 will be supported by the driving belts 53, and the smaller ones will fall into the sorting bin 51. At the same time, when the driving belts 53 move, they will drive the strawberries to the bottom shaft 54. The strawberries will be lifted by the baffle on the bottom shaft 54 to prevent some strawberries from getting stuck between the driving belts 53 and affecting the sorting work.

[0062] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
