[0025] The utility model provides a kind of sweet persimmon freeze-drying fresh-keeping storage equipment, including device main body 11, device main body 11 is provided with door panel 12, the inside of device main body 11 is provided with vibration mechanism, including U-shaped plate 16, rotating plate 18 and rotating column 19, the inside of device main body 11 is provided with placing mechanism 13, placing mechanism 13 is used to place sweet persimmon, U-shaped plate 16 is located in the inside of device main body 11, U-shaped plate 16 is located in the lower end position of placing mechanism 13, the lower end of U-shaped plate 16 is fixedly connected with the inner wall of device main body 11, rotating column 19 is located in the inside of U-shaped plate 16, the both ends of rotating column 19 are rotatably connected with U-shaped plate 16, the end of rotating plate 18 is fixedly connected with rotating column 19, rotating column 19 rotates and drives rotating plate 18 to rotate, rotating plate 18 rotates with rotating column 19 as center at this time, when rotating plate 18 moves to the bottom of placing mechanism 13, rotating plate 18 contacts with placing mechanism 13, and rotating plate 18 lifts placing mechanism 13 at this time.

[0026] The lower end of placing mechanism 13 is fixedly connected with fixed cylinder 14 in four corners, the lower end of each fixed cylinder 14 is provided with connecting column 15, the side end of U-shaped plate 16 is fixedly connected with motor 17, the output port of motor 17 is fixedly connected with rotating column 19 through U-shaped plate 16, and motor 17 is started, and motor 17 drives rotating column 19 to rotate.

[0027] The upper end of four connecting columns 15 is movably sleeved with corresponding fixed cylinder 14, the both ends of each fixed cylinder 14 are provided with limiting block 22, the both ends of each fixed cylinder 14 are provided with long slot 21, each long slot 21 is corresponding with the position of each limiting block 22, each limiting block 22 is fixedly connected with corresponding connecting column 15 through long slot 21, limiting block 22 limits the relative motion between connecting column 15 and fixed cylinder 14, it is fixedly connected with connecting column 15 through the long slot 21 of both ends of fixed cylinder 14, prevents connecting column 15 from being taken out of fixed cylinder 14, and the stability in vibration process and the reliability of structure of placing mechanism 13 are guaranteed.

When the rotating plate 18 lifts up the placing mechanism 13, the four springs 20 reset. At this time, the rotating plate 18 continues to rotate and no longer pushes the placing mechanism 13. The placing mechanism 13 descends and compresses the spring 20. After the rotating plate 18 rotates one circle, it will push the placing mechanism 13 again, so as to achieve the purpose of repeated lifting of the placing mechanism 13.

Therefore, the sweet persimmons can maintain the cell structure as much as possible, and after rehydration, the sweet persimmons can restore the original taste, such as still having a crisp or soft taste, and improve the eating experience.

[0029] Working principle:

[0030] First step, start the motor 17, the motor 17 will drive the rotating column 19 to rotate, the rotating column 19 rotates and drives the rotating plate 18 to rotate. At this time, the rotating plate 18 rotates with the rotating column 19 as the center. When the rotating plate 18 moves to the bottom of the placing mechanism 13, the rotating plate 18 contacts the placing mechanism 13. At this time, the rotating plate 18 lifts up the placing mechanism 13. The initial state of the four springs 20 is in a compressed state being extruded by the placing mechanism 13. When the rotating plate 18 lifts up the placing mechanism 13, the four springs 20 reset. At this time, the rotating plate 18 continues to rotate and no longer pushes the placing mechanism 13. The placing mechanism 13 descends and compresses the spring 20. After the rotating plate 18 rotates one circle, it will push the placing mechanism 13 again, so as to achieve the purpose of repeated lifting of the placing mechanism 13. The repeated lifting can simulate a vibrating environment. The vibration helps to destroy the growth of ice crystals, makes the distribution of ice crystals more uniform and small, prevents the formation of large ice crystals, avoids that large ice crystals may damage the cell structure of sweet persimmons, causes cell rupture, and affects the taste, texture and nutrient retention of sweet persimmons in the subsequent drying and rehydration processes. Therefore, the sweet persimmons can maintain the cell structure as much as possible, and after rehydration, the sweet persimmons can restore the original taste, such as still having a crisp or soft taste, and improve the eating experience.
