DETAILED DESCRIPTION

[0016] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0017] As shown in Figure 1 and Figure 2 , the double-flow channel plate layer uniform temperature freeze-drying machine comprises a freeze-drying machine body, a freeze-drying box 1 for storing freeze-drying bottles 4 is arranged in the freeze-drying machine body, a partition plate 2 is arranged in the middle of the freeze-drying box 1, the freeze-drying box 1 is divided into two freeze-drying chambers 3 in the upper and lower directions by the partition plate 2, a plurality of freeze-drying bottles 4 for placing samples are arranged in the freeze-drying chambers 3, two independent cold air channels are formed by the two freeze-drying chambers 3, a sliding rail 5 is arranged at the top of each freeze-drying chamber 3, a sliding block 6 is slidably arranged on the sliding rail 5, a monitor 7 is arranged at the bottom of the sliding block 6, and the sliding block 6 is movable on the sliding rail 5 through a driving device.

[0018] The driving device drives the sliding block 6 to move on the slide rail 5, and the movement of the sliding block 6 drives the monitor 7 to shift to different positions to align with different freeze-drying bottles 4 below, so as to collect temperature data of each freeze-drying bottle 4.

[0019] The edge of the partition plate 2 is provided with a gap, the gap connects the two freeze-drying chambers 3, and the two sliding blocks 6 are connected through a bracket body 8 in the shape of a "concave" character.

[0020] After the two sliding blocks 6 are fixedly connected through the bracket body 8, only one driving device is needed to drive the two sliding blocks 6 to move back and forth at the same time, and as long as the positions of the freeze-drying bottles 4 are aligned up and down, the two groups of monitors 7 will be synchronized during the collection process, thereby increasing the monitoring efficiency.

[0021] The bracket body 8 is provided with a partition block 9, the partition block 9 is in the same plane as the partition plate 2, the left and right ends of the partition block 9 are provided with wrinkle connecting pieces 10, the other ends of the two wrinkle connecting pieces 10 are fixed in the two edges of the freeze-drying box 1, the wrinkle connecting pieces 10 can be freely stretched and contracted, and the wrinkle connecting pieces 10 block the gap to separate the freeze-drying chambers 3 from each other.

[0022] The sliding block 6 needs to be adjusted in position to change the monitoring function, the sliding block 6 drives the bracket body 8 to move, and the partition block 9 moves together with the bracket body 8, during the movement of the partition block 9, the wrinkle connecting pieces 10 on the two sides are automatically lengthened or retracted, but because the wrinkle connecting pieces 10 have folding ability (similar to the protective cover of an accordion), the wrinkle connecting pieces 10 will always block the gap, so that the two freeze-drying chambers 3 will not be connected due to the existence of the gap.

[0023] The driving device comprises a movable block 11 fixed on the bracket body 8, a numerical control motor 12 fixed in the freeze-drying box 1, and a transmission screw 13 rotationally arranged in the freeze-drying box 1, the numerical control motor 12 is in butt joint with the transmission screw 13, and the movable block 11 is provided with a screw hole matched with the transmission screw 13 and is in butt joint with the transmission screw 13 through the screw hole.
