Bottled culture medium backwashing device

Abstract

A bottled culture medium backwashing device comprises a water supply pipe and a culture medium bottle inversion notch. A transmission gear is arranged at the position, close to the lower end, of the water supply pipe. A sealed bearing is arranged at the lower end of the water supply pipe, and a water inlet is further formed in the side wall of the sealed bearing. A water jet pipe is separately arranged in the middle of the water supply pipe. An annular brush used for cleaning the inner bottleneck of a culture medium bottle is fixedly arranged at the upper end of the water supply pipe, the height where the annular brush is arranged is larger than the horizontal height of a nozzle at the upper end of the water jet pipe, the horizontal position where the annular brush is arranged is flush with a bottleneck clamping and releasing section on the lower portion of the culture medium bottle inversion notch, a hold-down ring used for holding bristles is arranged in the middle of the annular brush, a bristle gap is formed in the annular brush, the bristle gap is located over the nozzle arranged at the upper end of the water jet pipe in installation, and the distance between the most front ends of the bristles of the annular brush and the culture medium bottle inversion notch is 0.5-4 mm.

Description

technical field [0001] The invention belongs to the technical field of strain planting equipment development, and relates to a backwashing device, in particular to a backwashing device used for cleaning the exposed surface of a bottled culture medium and the mouth of a bacteria culture bottle. Background technique [0002] Bacteria planting has very strict requirements on environmental factors, and any unfavorable factors to the bacteria may cause infection of the bacteria, so the cleaning work in the process of growing the bacteria is particularly important. [0003] In the prior art, the bottled medium will undergo a long-term transshipment process on the flow line after it has just been bottled, or it will be shelved for a period of time in an environment under non-bacterial conditions, where it is circulated or shelved During the process, the mouth of the bacteria culture bottle and the exposed surface of the culture medium are prone to mold growth, and the culture mediu...

[0003] In the prior art, the bottled medium will undergo a long-term transshipment process on the flow line after it has just been bottled, or it will be shelved for a period of time in an environment under non-bacterial conditions, where it is circulated or shelved During the process, the mouth of the bacteria culture bottle and the exposed surface of the culture medium are prone to mold growth, and the culture medium will be fully infected if it is slightly improperly handled, which will also affect the germination of the culture medium and the robust growth of fruiting bodies; the culture medium is composed of various organic The material composition has a certain degree of softness, so a thin layer of the exposed surface will generally be washed off during the water flushing process, so the mold growing on the exposed surface of the culture medium will also be thoroughly cleaned. All molds are attached to the bacteria culture bottle, and the water column cannot completely wash the inner bottle mouth when washing, so after cleaning, there are often some culture medium residues left in the bottle mouth of the bacteria culture bottle, and mold and other microorganisms may adhere to the residue , in the state of incomplete cleaning, the germination rate will drop by 5%-20% compared with the clean state, which seriously affects the output and quality of edible fungi
