[0002] Freeze-dried edible fungi are a kind of edible fungi product that has been specially processed. The production process adopts freeze-drying technology, that is, freezing the fresh mushrooms under low temperature conditions, and then sublimating the water in a vacuum environment to obtain a dry edible fungi product.

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] Excessive water in the freeze-drying process will prolong the sublimation phase of the freeze-drying process, because more energy is needed to convert the water directly from solid to gas. This not only increases the energy consumption of the freeze dryer, but also reduces production efficiency. Therefore, in order to solve the above problems, this case proposes the following technical solutions: See also Figures 1 to 6The present invention provides a freeze-dried edible fungus processing equipment and a processing method thereof.

[0028] When in use, the main structure of the device includes a freeze drying box 1 for freeze drying. The freeze drying box 1 is sealed by an outer cover 2 on the side of a movable shaft 15. The refrigeration is circulated through a refrigerator 5 at the bottom of a base 3 and a circulating pump 4 with a circulating inner tube 12 to reduce the temperature.

[0029] The inner circulating pipe 12 inside the box body 11 is arranged on the side of the bracket 14, and a movable inner tray 13 is arranged between the brackets 14. A drainage pipe 6 is installed on the side of the bracket 14, and the drainage pipe 6 is connected to the inner tray 13 for pre-drainage.

[0030] The structure of the inner tray 13 includes a guide net 131 and an outer frame 133. The guide net 131 is composed of a first guide net 311, a second guide net 314 and a rotating shaft 315. The side edges are protected by supports 313 to prevent mushrooms from getting stuck in the side seams during shaking.

[0031] A mesh 132 is provided between the guide net 131 and the outer frame 133. The mesh 132 is made of a stainless steel soft metal net. The first guide net 311 is connected to the outer frame 133 through a side rod 312. One group of side rods 312 is movably connected to the outer frame 133, and one group is fixedly connected to the outer frame 133. A drainage pipe 134 is provided on the side of the outer frame 133. The drainage pipe 134 is used for drainage of the outer frame 133.

[0032] The structure of the outer frame 133 includes a frame body 331, and the frame body 331 has a groove body formed by bending side grooves 330 on both sides, and a fixed wheel 332, an adjusting wheel 333 and a driving wheel 335 are sequentially arranged in the groove body, the fixed wheel 332 is fixed to the inner wall of the frame body 331, the adjusting wheel 333 cooperates with the sliding groove of the frame body 331, and the driving wheel 335 is fixed to the side wall of the frame body 331, wherein the adjusting wheel 333 and the driving wheel 335 are connected through a driving belt 334, and the driving belt 334 is bent by rotating the adjusting rotating rod 337 through the first limiting rod 338, when the second limiting rod 339 fixed at the main shaft of the loose adjusting wheel 333 is loosened, the adjusting wheel 333 can be moved, and the moving stroke of the adjustable frame 331 of the moving adjusting wheel 333 in the push-in bracket 14 makes the swinging time controllable to avoid the mushrooms from clumping after shaking.

[0033] The structure that produces shaking is that the driving wheel 335 drives the connecting rod 336 to move in the inner groove of the side groove 330. When the driving wheel 335 rotates, the pull rod of the connecting rod 336 swings, driving the internal sliding rod to reciprocate. When pushing, the first guide net 311 and the second guide net 314 arch upward, and shake downward when resetting.

[0034] The support 313 includes a limiting plate 301, which is in an arc shape, and is provided with a side slide groove 302 on the side to be nested with the side rod 312 and the edge between the second guide net 314. The side of the limiting plate 301 is locked by a limiting shaft 303, and a movable bottom block 304 is provided at the bottom of the limiting plate 301. The bottom block 304 and the limiting plate 301 are connected by a spring 305, which can generate buffering when swinging up and down, and can also vibrate.
