Description

Technical Field

[0001] This utility model relates to the technical field of quick-freezing and preservation devices, and in particular to a quick-freezing and preservation device for yellow-skinned fruit. Background Technology

[0002] Wampee, a tropical and subtropical fruit, possesses unique flavor and nutritional value. However, due to its high water content and vigorous metabolism, it is extremely prone to spoilage after harvesting, severely limiting its market circulation and industrial development. Quick-freezing preservation technology, as an effective means of extending fruit shelf life, is gradually gaining attention in the field of wampee preservation. By rapidly cooling wampee to below freezing point, its physiological activity can be significantly reduced, inhibiting microbial growth and thus preserving the fruit's quality and flavor.

[0003] However, current traditional quick-freezing and preservation equipment commonly suffers from the problem of wampee sticking together after quick-freezing. During the quick-freezing process, the moisture on the surface of the wampee freezes rapidly, and the ice layers of adjacent wampee peels connect with each other, causing them to stick together. This sticking not only affects the appearance integrity of the wampee but also causes many inconveniences in subsequent handling, packaging, and sales. For example, during handling, the sticking wampee peels may be squeezed and damaged due to uneven force, reducing product quality; during packaging, extra time and manpower are required to separate them, reducing packaging efficiency and increasing labor costs; for consumers, the sticking wampee peels are inconvenient to handle, affecting the consumer experience.

[0025] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1 to 4 As shown, this application provides a quick-freezing and preservation device for yellow-skinned fruit, comprising:

[0027] The quick-freezing equipment 100 includes a frame 10, a pre-cooling mechanism 20, and a drying mechanism 30. A belt conveyor 11 is fixedly installed inside the frame 10. An insulation cover 15 is fixedly installed on the upper side of one side of the frame 10. A control panel 16 is fixedly installed on the outer wall of the insulation cover 15 by bolts. The pre-cooling mechanism 20 is located on the left side of the frame 10. The drying mechanism 30 is located on the upper left side of the frame 10. The quick-freezing mechanism 40 is located on the right side of the frame 10 and includes a liquid nitrogen tank 41 and a liquid nitrogen pump 42 fixedly installed on the top of the insulation cover 15, and a quick-freezing chamber 4 located on the right side of the frame 10. 8 and multiple cooling pipes 43 fixedly installed on the inner wall of the insulation cover 15. The input end of the liquid nitrogen pump 42 is fixedly connected to one side of the liquid nitrogen tank 41 through a hose. The output end of the liquid nitrogen pump 42 is fixedly connected to the upper wall of one side of the cooling pipe 43 through a hose. A connecting pipe 46 is fixedly installed between two adjacent cooling pipes 43. Multiple air outlets 47 are opened on the upper surface of the multiple cooling pipes 43. A pulse fan 44 is fixedly installed at the bottom of the quick-freezing chamber 48. An air collecting hood 45 is fixedly installed on the upper surface of the quick-freezing chamber 48. The output end of the pulse fan 44 is fixedly connected to the bottom of the air collecting hood 45.

[0028] After adopting the above technical solutions, the pre-cooling mechanism 20 is set to pre-cool the yellow peel, thereby reducing the time required for quick-freezing. The drying mechanism 30 is set to dry the pre-cooled yellow peel, preventing multiple yellow peels from sticking together during quick-freezing. The quick-freezing mechanism 40 is set to quick-freeze the pre-treated yellow peel. The quick-freezing mechanism 40 blows the yellow peel to contact with liquid nitrogen, thereby quick-freezing the yellow peel. On the one hand, after the yellow peel is blown up, it is in a dispersed state, and the surface of each fruit can be directly exposed to liquid nitrogen gas, increasing the heat transfer area and improving the quick-freezing efficiency. On the other hand, after the yellow peel is blown up, it is in a dispersed suspension or dynamic turning state, maintaining a certain gap between the fruits, reducing the chance of mutual compression or sticking, and avoiding the adhesion caused by long-term close contact.

[0029] It should be noted that the ice-water mixture is first poured into the pre-cooling chamber 21, and then the yellow peel that needs to be quick-frozen is poured into the pre-cooling chamber 21. After the yellow peel comes into contact with the ice-water mixture, it is pre-cooled. After the yellow peel is pre-cooled, the belt conveyor 11 operates to pick up the yellow peel from the pre-cooling chamber 21 and transport it through the belt conveyor 11. When the yellow peel is transported to the bottom of the drying mechanism 30, the fan 32 operates to blow off the water droplets on the outer wall of the yellow peel, preventing the water droplets from freezing multiple yellow peels together after quick-freezing and forming blocky ice clumps. After the yellow peel is dried, it is sent into the insulation hood 15 through the belt conveyor 11. The pulse fan 44 operates to generate pulse airflow to intermittently blow the yellow peel on the belt conveyor 11, so that the yellow peel is... During the blowing process, the liquid nitrogen pump 42 pumps the liquid nitrogen from the liquid nitrogen tank 41 into the cooling pipe 43. The liquid nitrogen in the cooling pipe 43 enters the heat preservation cover 15, absorbs heat and vaporizes, thereby rapidly reducing the temperature inside the heat preservation cover 15. The vaporized liquid nitrogen is discharged through the vent 47 and comes into full contact with the blown yellow peel. On the one hand, after the yellow peel is blown up, it is in a dispersed state, and the surface of each fruit can be directly exposed to the liquid nitrogen gas, which increases the heat transfer area and improves the quick-freezing efficiency. On the other hand, after the yellow peel is blown up, it is in a dispersed suspension or dynamic turning state, and a certain gap is maintained between the fruits, reducing the chance of mutual compression or sticking, avoiding the adhesion caused by long-term close contact, thus quick-freezing the yellow peel and preventing the quick-frozen yellow peel from sticking together.

[0030] In an optional embodiment, the precooling mechanism 20 includes a precooling chamber 21 and an ice-feeding chamber 22 located on the left side of the frame 10. The ice-feeding chamber 22 is located to the left of the precooling chamber 21. A partition is provided between the precooling chamber 21 and the ice-feeding chamber 22, and the outer wall of the partition is provided with a plurality of evenly distributed connecting holes 23. By introducing an ice-water mixture into the precooling chamber 21 to precool the yellow peel, the time required for quick freezing of the yellow peel is reduced. At the same time, by introducing ice blocks into the ice-feeding chamber 22 to exchange heat with the ice-water mixture in the precooling chamber 21, the temperature in the precooling chamber 21 is kept stable.

[0031] In an optional embodiment, the drying mechanism 30 includes a connecting frame 31 fixedly installed at the upper middle part of the pre-cooling chamber 21, and a plurality of fans 32 fixedly installed on the top of the connecting frame 31 to dry the pre-cooled yellow peel.

[0032] In one optional embodiment, the two ends of the belt conveyor 11 are located inside the pre-cooling chamber 21 and the quick-freezing chamber 48, respectively. The belt conveyor 11 is set at an angle upward on one side of the pre-cooling chamber 21 and at a horizontal position on one side of the quick-freezing chamber 48. The inclined part of the belt conveyor 11 can lift the yellow skin on one hand and facilitate the dripping of water droplets from the outer wall of the yellow skin on the other hand.

[0033] In one optional embodiment, a plurality of equally spaced baffles 12 are fixedly installed on the outer wall of the conveyor belt of the belt conveyor 11, and a plurality of evenly distributed ventilation holes 13 are opened on the outer wall of the conveyor belt of the belt conveyor 11, so that the yellow skin in the pre-cooling chamber 21 can be picked up through the baffles 12.

[0034] In an optional embodiment, an insulation curtain 17 is fixedly installed on the outer left side of the insulation cover 15 to improve the insulation performance inside the insulation cover 15.

[0035] In one optional embodiment, an electric door 14 is provided on the lower right side wall of the quick-freezing chamber 48, and the quick-frozen yellow peel is discharged by opening the electric door 14.
