[0033] A sterilization shelf for a pressure steam sterilizer described in the present invention is adopted, and the drainage layer 4 and the water accumulation layer 3 are arranged to cooperate with each other. Different from the shelf in the prior art, the first opening 6 and the drainage layer 4 reduce the contact area between the article and the sterilization shelf 1. During the drying process, the condensed water on the outer wall of the article will move toward the sterilization shelf 1 under the action of gravity, and the condensed water moves toward the second opening 7 through the drainage layer 4 to the water accumulation layer 3 for collection, which effectively reduces the retention of condensed water in the contact area between the article and the drainage layer 4, thereby reducing the moisture of the article and preventing the formation of wet bags in the bag during the drying process.

[0034] Specifically, the sterilization layer plate 1 is made of a high temperature resistant material.

[0035] As a preferred embodiment, based on the above method, the water accumulation layer 3 and the drainage layer 4 are further connected by sliding, and the water accumulation layer 3 will move toward the ground side as the liquid increases. With this structural setting, the liquid level in the water accumulation layer 3 maintains a gap with the first opening 6, which reduces the contact between the liquid level and the items during the collection of condensed water, further reduces the moisture of the items, and prevents the generation of wet bags in the bag during the drying process.

[0036] In Example 2: Figures 1 to 3 As shown, the utility model describes a sterilization shelf for a pressure steam sterilizer, including the drainage layer 4 including a contact area 8 and a guide area 9, the contact area 8 is in contact with the article, the guide area 9 guides water droplets to the water accumulation layer 3, a slide rail assembly 10 is arranged between the drainage layer 4 and the water accumulation layer 3, one end of the slide rail assembly 10 is connected to the contact area 8, and the other end of the slide rail assembly 10 is connected to the water accumulation layer 3, the movement direction of the slide rail assembly 10 is consistent with the direction of the guide area 9, when the water accumulation layer 3 moves to a preset critical state, the slide rail assembly 10 stops the water accumulation layer 3 from moving.

[0037] Specifically, the slide rail assembly 10 in this embodiment adopts the connection cooperation of a rotating column, a connecting rod, a spring and a bracket, the rotating column is connected to the contact area 8, the connecting rod connects the rotating column and the water accumulation layer 3, the spring is arranged at the connection between the rotating column and the connecting rod, when the water accumulation layer 3 moves toward the ground side, the connecting rod drives the rotating column to rotate around the center of the rotating column, and when the spring reaches the maximum deformation as the water accumulation layer 3 moves, the water accumulation layer 3 stops moving, and when cleaning the liquid in the water accumulation layer 3, the spring will restore the deformation to make the water accumulation layer 3 slide toward the drainage layer 4. The use of this structural setting effectively reduces the contamination of the items placed on the lower layer caused by the separation of the water accumulation layer 3 and the drainage layer 4 due to the excessive liquid capacity during the collection process. The slide rail assembly 10 can effectively maintain the movement frequency of the water accumulation layer 3, and further maintain the relative stability of the water accumulation layer 3 and the drainage layer 4.

[0038] As a preferred embodiment, on the basis of the above-mentioned method, further, a bracket 11 is provided at the connection between the slide rail assembly 10 and the contact area 8, and the length of the bracket 11 exceeds the edge of the contact area 8. When the slide rail assembly 10 moves toward the water accumulation layer 3, the bracket 11 rotates with the center of the contact area 8 as the center of the circle and the length of the bracket 11 as the radius. During the rotation process, the bracket 11 contacts the object, causing the contact area between the object and the contact area 8 to change. With this structural setting, during the drying process, the bracket 11 rotates under the action of the slide rail assembly 10, and the bracket 11 collides with the object, causing the contact area between the object and the contact area 8 to change, thereby reducing the generation of wet bags on the object during the drying process, and further keeping the contact area between the object and the contact area 8 dry, effectively improving the practicality of the present invention in actual use.

[0039] Specifically, the bracket 11 is made of a material that is resistant to high temperatures and is not easily deformed.

[0040] As a preferred embodiment, on the basis of the above-mentioned method, further, the side of the guide area 9 facing the ground is provided with a vent hole 12, and the vent hole 12 is used to connect the inside of the guide area 9 with the external environment. With this structural setting, during the drying process, saturated steam will be concentrated on the top of the sterilization layer, and the steam will move toward the guide area 9 to the water accumulation layer 3 through the vent hole 12, reducing the water droplets after the steam condenses and dripping onto the articles during the drying process, and further reducing the generation of wet bags on the articles during the drying process.

[0041] As a preferred embodiment, on the basis of the above-mentioned manner, further, a water-absorbing layer 13 is provided inside the guide area 9, and the water-absorbing layer 13 is used to absorb water droplets condensed from the external environment into the guide area 9 through the air holes 12, and the air holes 12 penetrate the water-absorbing layer 13.

[0044] As a preferred embodiment, on the basis of the above-mentioned method, further, a height limiting plate 15 is provided on the side of the shelf body 2 facing the ground, and the height limiting plate 15 is used to reduce the collision between the objects and the inner wall of the sterilizer pot, and the central axis of the height limiting plate 15 is kept parallel to the central axis of the shelf body 2. With this structural setting, the height limiting plate 15 effectively maintains the stable state of the objects, and at the same time, the height limiting plate 15 can maintain the gap between the objects, reducing the contamination of the sterilization layer plate 1 caused by the objects tipping over during the drying process.

[0045] As a preferred embodiment, on the basis of the above-mentioned method, further, the shelf body 2 is provided with a detachable railing 16, which is used to fix the position of the article and the shelf body 2 to prevent it from slipping, and the detachable railing 16 and the shelf body 2 are detachably connected.
