Description

Technical Field

[0001] The utility model relates to the technical field of preserved fruit processing equipment, in particular to a preserved fruit sterilization and drying device. Background Art

[0002] Drying is one of the oldest preservation technologies. It can remove a large amount of moisture from fruits and reduce physical and chemical changes during storage, thereby inhibiting the growth of microorganisms and extending their shelf life. At the same time, drying can reduce the weight and volume of food, and reduce packaging, storage and transportation costs. Hot air drying is simple to operate and low in cost. High temperature will make the surface of the fruit dry and hard, and nutrients will be lost, and the taste will deteriorate. Low temperature, slow drying speed, low thermal efficiency, and accompanied by the risk of microbial growth. Microwave drying has a fast rate, rapid dehydration and hardening, and is difficult to control. Microwave-hot air drying can improve energy efficiency while maintaining product quality, overcome the shortcomings of a single drying method, but its actual production operation is difficult. Vacuum freeze drying dehydrates by sublimation under vacuum conditions, which can effectively preserve the color and shape of food, but its application range is limited and the production cost is high.

Specific embodiments

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0025] Embodiment: As Figures 1-5 shown, a preserved fruit sterilization and drying device includes a feeding box 1, a first conveying mechanism 2 arranged in the feeding box 1, a drying box 3 arranged behind the feeding box 1, a second conveying mechanism 4 arranged in the drying box 3, and a material tray 5 conveyed from the feeding box 1 into the drying box 3, wherein a part of the first conveying mechanism 2 is located in the feeding box 1, and the other part is located outside and is docked with the second conveying mechanism 4.

[0026] A feed hopper 6 is arranged at the top of the feeding box 1, and a spreading device 10 is arranged in the feeding box 1, and the spreading device 10 is located above the material tray 5.

[0027] As Figure 2As shown in the figure, the material laying device 10 includes a slide rail 1001 provided on the side wall of the feeding box 1, a moving frame 1002 that moves horizontally along the slide rail 1001, a material laying push plate 1003 fixed below the moving frame 1002, and a chain drive mechanism 1004 that drives the movement of the moving frame 1002. The chain drive mechanism 1004 is composed of a conventional sprocket and a chain. The sprocket is driven by a motor to rotate. The end of the chain is fixedly connected to the moving frame 1002. When the motor drives the sprocket to rotate, the sprocket pulls the moving frame 1002 to move horizontally along the slide rail 1001, so as to flatten the dried fruits in the lower material tray 5.

[0028] As Figure 1 and Figure 5 shown in the figure, a guiding plate 7 is provided below the feeding hopper 6, and the guiding plate 7 is arranged to slope downwards. The upper end of the guiding plate 7 is hinged to the top of the feeding box 1, the other end of the guiding plate 7 is connected to the top of the feeding box 1 through an elastic connecting member 8, and a vibration motor 9 is installed below the guiding plate 7.

[0029] The elastic connecting member 8 includes two nested sleeve rods 801 and a spring 802 connected between the two sleeve rods 801. The ends of the two sleeve rods 801 are hinged to the guiding plate 7 and the feeding box 1. One of the sleeve rods 801 has a hollow structure, and the other sleeve rod 801 is inserted inside this sleeve rod 801. One end of the spring 802 is connected to the end of one sleeve rod 801, and the other end is connected to the end of the other sleeve rod 801.

[0030] When the dried fruits in the feeding hopper 6 fall onto the lower guiding plate 7, the dried fruits slide down along the guiding plate 7 and are scattered and fall into the lower material tray 5 under the vibration of the vibration motor 9, preventing the dried fruits from sticking together.

[0031] As Figure 4 shown in the figure, a screen 501 is arranged in the material tray 5. The screen 501 is horizontally arranged above the bottom of the material tray 5. A screening area 502 is formed between the screen 501 and the bottom of the material tray 5 for screening out impurities attached to the dried fruits.

[0032] As Figure 3As shown in the figure, the first conveying mechanism 2 includes a conveying frame 201 and a conveying track 202 arranged on the conveying frame 201. The conveying track 202 is driven by two front and rear driving rollers 203. There are convex strips 204 on the back of the conveying track 202, and the convex strips 204 are linearly and spacedly distributed. A retaining rod 205 is arranged on the conveying frame 201. The retaining rod 205 is located on the back of the conveying track 202 and is linearly and spacedly distributed in the feeding box 1. The upper end of the retaining rod 205 is in an arc structure. When the convex strip 204 on the conveying track 202 passes by the retaining rod 205, it is blocked by the retaining rod 205 and moves upward, causing the conveying track 202 to jolt, thereby generating a vibrating effect on the material tray 5, facilitating the screening of impurities attached to the dried fruits.

[0033] The second conveying mechanism 4 adopts a conventional chain plate conveyor, which can withstand the high temperature in the drying oven 3.

[0034] An air outlet 11 and a sterilization component 12 are arranged on the top of the drying oven 3. A suction fan is installed at the air outlet 11. The sterilization component 12 uses ultraviolet lamps to inhibit the growth of microorganisms.

[0035] An air inlet 13, an air filter 14 and an electric heating component 15 are arranged at the bottom of the drying oven 3. The air filter 14 is located at the air inlet 13. The electric heating component 15 is located inside the drying oven 3 and is used to heat the drying oven 3. The electric heating component 15 adopts a conventional electric heating wire or electric heating rod.

[0036] During drying, the electric heating component 15 heats the temperature inside the drying oven 3 to 60 °C, turns on the ultraviolet lamp, and then the material tray 5 with dried fruits laid flat is conveyed to the second conveying mechanism 4 through the first conveying mechanism 2 and is conveyed into the drying oven 3 by the second conveying mechanism 4 for drying.
