as shown in fig. 1-2, a heat pump dryer of an edible fungi drying device is provided, the working principle of the heat pump dryer can be seen in the prior patent CN217686264U, the heat pump dryer comprises a heat pump dryer body 10, an exhaust fan assembly 11, a control unit 12, a drying cavity door plate 13, an air inlet assembly 14 and other structures are arranged on the heat pump dryer body 10. The drying chamber door 13 is used for closing the drying chamber 20, the drying chamber 20 can be exposed after the drying chamber door 13 is opened, fig. 3 schematically shows the structure of the drying chamber 20, it can be seen that the drying chamber door 13 comprises a drying chamber first side plate 21, a drying chamber second side plate 22 is located at two sides of the drying chamber 20 and defines the horizontal dimension of the drying chamber 20, and a plurality of tray bodies 30 are sequentially arranged from top to bottom to form a multi-layer drying rack.

In the heat pump dryer of the prior art, in order to allow the tray to conveniently enter and exit the drying chamber 20, the horizontal dimension of the tray assembly is compared with the horizontal dimension of the drying chamber 20, and a larger dimension difference is provided, that is, more gaps are left, but when the tray is actually installed, the tray enters horizontally but is usually twisted horizontally, one corner of the tray is abutted against the first side plate of the drying chamber, and the operation of pushing the tray is greatly affected by the abutment.

Referring to fig. 4-5, the contribution of the present utility model with respect to the prior art is first of all to propose a tray assembly of a heat pump dryer comprising: a first tray support 23, which is positioned in the drying chamber 20 of the heat pump dryer, and is fixed to the drying chamber first side plate 21; a second tray support 24 fixed to the drying chamber second side plate 22 of the drying chamber 20 and corresponding to the first tray support 23 in position; the tray body 30, it locates in the drying chamber 20 and both ends are supported by the first tray support 23, second tray support 24, the tray body 30 includes the bottom plate 34 and surrounds the sidewall 35 around the bottom plate 34, in this embodiment, the first tray support 23 includes the support body, the support body includes the deflector 25 from top to bottom at least, the carrier plate 27 and fixed plate 26, wherein deflector 25 and fixed plate 26 are fixed on first lateral plate 21 of the drying chamber, the carrier plate 27 is disposed horizontally and locates between deflector 25 and fixed plate 26, the bottom plate 34 of the tray body 30 is put on the carrier plate 27; the lower end of the side wall 35 of the tray body 30 is provided with a lower edge 33, the surface of the lower edge 33 facing the guide plate 25 of the support body is a first guide surface, and the first guide surface is matched with the guide plate 25 and is guided and limited by the guide plate 25.

The guide plate 25 and the fixing plate 26 are both fixed to the first side plate of the drying chamber, but the fixing manner is not limited, and may be fixed by screws or may be fixed by welding. In this embodiment, the guide plate 25, the supporting plate 27 and the fixing plate 26 are integrally formed, and the fixing method is that the fixing plate 26 below is fixed on the first side plate of the drying chamber by bolts, and then the edge of the guide plate 25 is welded on the first side plate of the drying chamber by spot welding.

Due to the presence of the guide plate 25, although the horizontal dimension of the tray assembly has a larger dimension difference compared with the horizontal dimension of the drying chamber 20, at the position of fixedly installing the tray, the guide plate 25 occupies a part of space into the drying chamber 20, so that the installation space of the tray is reduced, the installation accuracy of the tray is improved, the tray is guided by the guide plate 25 and basically no torsion in the horizontal direction occurs, and the lower edge 33 of the tray is matched with the guide plate 25, so that the tray can be smoothly pushed into the drying chamber 20.

The material of the guide plate 25 may be the same as or different from the first side plate of the drying cavity, and the guide plate 25 can eliminate the large pushing resistance of the tray because the contact condition between the corner of the tray and the first side plate of the drying cavity caused by the horizontal torsion of the tray can be eliminated, so that the material of the guide plate 25 does not put higher requirements; of course, the guide plate 25 may be selected to have a smoother surface configuration.

Preferably, the second tray support 24 has the same structure as the first tray support 23 and is fixed to the drying chamber second side plate 22.

Example 2:

in addition to the features of the foregoing embodiments, the present embodiment further describes a tray, and the tray body 30 further includes: an upper edge 31 at the upper end of the side wall 35; the outer side of the side wall 35 of the tray body 30 is provided with a plurality of guide ribs 32 protruding outwards, the guide ribs 32 are located between the upper edge 31 and the lower edge 33, and the side surfaces of the plurality of guide ribs 32 facing the guide plate 25 jointly form a second guide surface which can be guided and limited by the guide plate 25.

In this embodiment, the second guide surface formed by the plurality of guide ribs 32 can also assist the pushing operation of the tray, and the guide and limit of the tray can be realized by cooperating with the guide plate 25. Unlike the continuous first guide surface of the lower edge 33, the second guide surface formed by the plurality of guide ribs 32 is a guide surface formed by spaced surfaces which, in use, contact the guide plate 25 to reduce friction between the two surfaces and further reduce the difficulty of pushing into the tray.

Example 3:

in addition to the features of the foregoing embodiments, the present embodiment further describes a tray, and the tray body 30 further includes: the bottom plate 34 is provided with a vent hole matrix, the side wall 35 is also provided with a vent hole matrix, the side surface of the guide rib plate 32 facing the guide plate 25 is obliquely arranged, and the upper end of the guide rib plate 32 is closer to the guide plate 25 than the lower end.

In the drying and dewatering process of the edible fungi, the temperature of the hot dry air in the drying chamber is between 20 and 80 ℃ through the working condition of the control device, so that the high-quality drying requirements of most edible fungi can be met, and meanwhile, the material drying quality can be ensured only by ensuring the closed circulation drying of the low-temperature air. Thus, in this embodiment, considering ventilation requirements, not only is a matrix of ventilation holes provided on the tray body 30 and the side walls 35, but also the guide rib 32 is provided so as to be inclined toward the side of the guide plate 25, so that a gap through which the air flow passes can be formed, which facilitates the circulating air flow through the multi-layered tray.

Example 4:
