[0003] When the existing laboratory vacuum drying oven is in use, the vacuum pump inside is generally connected externally and built-in at the bottom. The external connection is cumbersome to operate each time, and the vibration generated by the built-in vacuum pump when in use will cause vibration to the entire vacuum drying oven, causing shaking of the bottle containing Escherichia coli stored inside, and when the bottle containing Escherichia coli is placed, it is generally not fixed, so that in the case of misoperation, the bottle will be dumped, resulting in work failure. Therefore, the present invention proposes a vacuum drying oven for producing small peptides based on Escherichia coli and a method for using the same. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a vacuum drying oven for producing small peptides based on Escherichia coli and a method for using the same. A shock-absorbing connection portion is provided at the connection between an internal vacuum pump and the vacuum drying oven, so that when the vacuum pump is working, the vibration generated by the vacuum pump can be weakened and absorbed by the shock-absorbing connection portion, so that it does not affect the stability of the entire vacuum drying oven. An elastic protective frame is provided on a placement plate for placing bottles, so that the placed bottles can be positioned and fixed, and the elastic protective frame can be conveniently replaced, which is convenient for replacing different bottles when placed, thereby improving flexibility in use.

10. The method for using the vacuum drying oven for producing small peptides based on Escherichia coli according to any one of claims 1 to 9, characterized in that: The steps include: S1. First, insert the bottle containing E. coli into the elastic clamp (701). The elasticity of the elastic clamp (701) is used to squeeze and hold the inserted bottle, and the anti-slip groove (702) provided inside the elastic clamp (701) can stabilize it. S2, then insert the elastic clamp (701) into the interior of the positioning hole (602) opened on the placement plate (600) through the positioning block (703) at the bottom, and at the same time, use the side wall of the positioning block (703) to engage with the elastic frame (704b) provided on the extrusion block (704) to press against the inner wall of the positioning hole (602), so that the positioning block (703) can drive the elastic clamp (701) to be fixed, and slide the multiple placed bottles through the side wall slide groove (601) of the placement plate (600) onto the slide rail (504), and then fix them inside the inner liner (500); S3, then closing the box door (104) and setting the required vacuum value and the temperature and humidity values ​​inside the inner container (500) through the control panel (102); S4, then starting the vacuum pump (400), the vacuum pump (400) extracts the internal air of the inner container (500) through the connecting pipe, and the changes are observed in real time through the pressure gauge on the control panel (102), and the vibration generated by the vacuum pump (400) during the extraction process is transmitted to the shock-absorbing connection unit (300) at the bottom; S5. Next, when the shock-absorbing connecting unit (300) is vibrated, it moves on the connecting column (304), thereby squeezing the movable frame (307). When the movable frame (307) is squeezed, it slides inside the movable groove (303a) through the limit block (307b), and at the same time drives the internal partition (307a) to squeeze the stabilizing sleeve (306), so that the stabilizing sleeve (306) slides on the connecting column (304) and squeezes the damping spring (305) at the bottom. ) is squeezed, and the pressure received can be absorbed under the compression action of the damping spring (305), thereby preventing excessive vibration from causing shaking of the vacuum pump (400). When the vacuum pump (400) is maintained at a later stage, the roller (202) on the push-pull plate (201) can be rolled inside the rolling groove (204) of the side plate (203), so that the vacuum pump (400) arranged on the push-pull plate (201) can be conveniently pulled out for maintenance, thereby improving the convenience in maintenance and installation; S6. After a certain vacuum is drawn, the heating tube (505) at the bottom of the inner liner (500) is started, so that the temperature and humidity of the environment inside the inner liner (500) can be regulated to achieve a certain drying effect. During a long period of storage, the operation of producing small peptides by Escherichia coli in the vacuum drying box (100) is realized.
