AI Technical Summary

Technical Problem

The depth of the low-temperature cavity of existing ultra-low-temperature refrigerators is too deep, making it inconvenient to store and access candidate strain raw materials. When turned on, the convection between cold air and the outside air causes drastic temperature fluctuations, affecting the storage stability of the strains and the life of the equipment.

Method used

A freezing device for chicken intestinal probiotic raw materials was designed, which adopted a lifting mechanism and a magnetic sealing layer. The lifting mechanism included a hydraulic cylinder, an articulated seat, a guide rod and a placement plate. Together with the magnetic sealing layer, the lifting mechanism could realize smooth opening of the cover and synchronous movement of the placement plate, thereby reducing cold air convection and maintaining a constant temperature and humidity environment.

Benefits of technology

It solves the operational inconvenience caused by the depth of the low-temperature chamber, reduces temperature fluctuations, improves strain preservation stability and equipment life, and simplifies the operating process.

Abstract

The invention relates to the technical field of ultralow-temperature cryopreservation of chicken intestinal probiotic raw materials, in particular to a chicken intestinal probiotic raw material cryopreservation device which comprises a cabinet, a lifting mechanism facilitating storage and taking of candidate strain raw materials is arranged on the cabinet, and the lifting mechanism comprises a first hinge seat, a second hinge seat, a supporting seat, a lap joint roller and a plurality of guide rods. A hydraulic cylinder is hinged to the first hinge seat, a placing plate is jointly and slidably connected to the guide rods, balancing weights which are symmetrically arranged are fixedly connected to the bottom end of the placing plate, a rotating rod is rotatably connected to the supporting seat, an extrusion rod is fixedly connected to the rotating rod, a connecting rod is fixedly connected to the extrusion rod, and the connecting rod is fixedly connected to the supporting seat. The device has the beneficial effects that extremely favorable conditions are created for a worker to store and take candidate strain raw materials, the inconvenience brought to operation of the worker due to the fact that the depth of a low-temperature cavity in the refrigerator is large is effectively solved, and meanwhile the problem that when a cabinet is opened, temperature fluctuates severely due to convection is avoided.
