At the same time, the temperature of the products is relatively high after drying, which is not conducive to subsequent material taking. Therefore, a tray-type vacuum oven is needed to solve the above problems. Summary of the Utility Model

Two groups of sliders are symmetrically installed at the bottom of the installation frame. A bearing mechanism is arranged inside the installation frame. A pushing mechanism for pushing the installation frame out of the oven housing is arranged on the back of the oven housing.

[0007] Preferably, the bearing mechanism includes multiple groups of grid frames arranged inside the installation frame. On both side surfaces of each group of grid frames, multiple groups of limiting rods are symmetrically installed. On the surfaces of two groups of limiting rods on the same side, a pressing plate is slidably connected in common. On the surface of each pressing plate, two groups of clamping joints are symmetrically installed. On the surface of each group of limiting rods, a first spring is sleeved.

[0008] Preferably, two groups of chutes adapted to the sliders are symmetrically opened at the bottom of the inner wall of the oven housing. Two groups of rectangular grooves adapted to the clamping joints are symmetrically opened on the inner surfaces of both sides of the installation frame. Multiple groups of slots adapted to the clamping joints are equidistantly opened in each rectangular groove.

[0009] Preferably, a baffle is installed at the end of each group of limiting rods. One end of the first spring is installed on the surface of the pressing plate, and the other end is installed on the surface of the grid frame.
