[0018] The following will be combined with the instructions attached Figure 1-3 And specific implementation methods are used to describe the above technical solutions in detail:
[0019] The utility model provides a negative pressure dehydration device for edible fungi, comprising an outer box body 1, the interior of the outer box body 1 is connected to an inner box body 2 through a connecting structure, the outer box body 1 and the inner box body 2 are provided with door 3 that cooperate with each other, the upper end of the outer box body 1 is fixedly connected to a first motor 4, the output shaft of the first motor 4 passes through the outer box body 1 and is fixedly connected to the inner box body 2, an air pump 5 is fixedly connected to one side of the upper end of the outer box body 1, the air pump 5 is connected to an exhaust pipe, the exhaust pipe passes through the outer box body 1 and extends to the inside of the outer box body 1, a plurality of ventilation holes 6 are opened on the inner box body 2, a screen 7 is fixedly connected to the ventilation holes 6, a pressure monitoring device is provided on the inner wall of the inner box body 2, and a control panel 8 is provided on the surface of the outer box body 1. When it is necessary to dehydrate the edible fungi, the box doors 3 on the outer box body 1 and the inner box body 2 are opened in turn, and the edible fungi are placed in the inner box body 2, and then the box doors 3 are closed in turn. Preferably, the gaps in the box doors 3 on the outer box body 1 are sealed, and then the power supply is connected and the control panel 8 is operated to start the first motor 4 and the air pump 5. The first motor 4 drives the inner box body 2 to rotate in the outer box body 1, so that the edible fungi in the inner box body 2 also rotate accordingly. Since the inner box body 2 is provided with air vents 6, the interior of the outer box body 1 and the interior of the inner box body 2 are connected and are in the same air pressure environment. During operation, the air pump 5 evacuates air from the interior of the outer box body 1, and at this time the inner box body 2 The air inside will also be extracted through the vent 6, so that the air pressure inside the outer box 1 and the inner box 2 will be reduced to form a negative pressure environment, so that the boiling and evaporation temperature of water will be reduced. When the pressure monitoring device detects that the internal air pressure reaches the preset value, the operation control panel 8 controls the true air pump 5 to stop working. At this time, the water in the edible fungi can boil and evaporate into water vapor to be discharged, thereby achieving a dehydration effect. Since the edible fungi will rotate with the inner box 2, its dehydration efficiency will be improved. Compared with the traditional high-temperature dehydration method, this device will not put the edible fungi in a high-temperature environment, and it is not easy to cause oxidation reaction and browning phenomenon, and it will not affect the appearance and taste of the dried edible fungi. After the dehydration is completed, first open the door 3 on the outer box 1. If the door 3 on the inner box 2 is not facing the door 3 of the outer box 1, the position can be adjusted by the first motor 4, and then open the door 3 on the inner box 2 and take out the dehydrated edible fungi. Preferably, the gap between the outer box 1 and the exhaust pipe and the output shaft of the first motor 4 is sealed.

[0023] As a preferred embodiment, an electric heating wire 14 is provided between the outer box 1 and the inner box 2, and a temperature monitoring device is provided on the inner wall of the inner box 2. During dehydration, the control panel 8 is operated to start the electric heating wire 14, and the electric heating wire 14 is energized to generate heat, thereby raising the temperature inside the device to a suitable preset temperature. With the aid of a negative pressure environment, dehydration can be performed better without lowering the internal pressure too much.
[0024] In order to absorb the water vapor formed in the negative pressure environment, as a preferred embodiment, a drying box 15 is fixedly connected to the upper inner wall of the outer box 1 and the upper inner wall of the inner box 2, and a through hole 16 is opened on the drying box 15, and a desiccant is arranged in the drying box 15.
