Automatic koji inoculating machine

Abstract

The invention relates to an automatic koji inoculating machine which comprises a tank. The tank is provided with a strain culture cavity, a container with a culture base material laid in is arranged in the strain culture cavity, the tank is further provided with a sterilizing mechanism and a negative-pressure inoculating mechanism, the sterilizing mechanism comprises an air flow incoming passage and an air flow outgoing passage, one end of the air flow incoming passage is communicated with the strain culture cavity while the other end of the same is communicated with a steam supply source and a sterile air source and can switch between the two, and one end of the air flow outgoing passage is communicated with the strain culture cavity while the other end of the same is communicated with an air liquid collection source; the negative-pressure inoculating mechanism comprises an inoculating pipe, an inoculating tank and a negative-pressure passage, the inoculating pipe and the negative-pressure passage are positioned on two sides of the tank, the inoculating pipe communicates the inoculating tank with the strain culture cavity and is provided with a an inoculating control valve for controlling on-off of the inoculating pipe, and one end of the negative-pressure passage is communicated with the strain culture cavity while the other end of the same is communicated with a negative-pressure generator. By adopting the above scheme, the automatic koji inoculating machine is good in sterilizing effect and quick and uniform in inoculating.

Description

technical field [0001] The invention relates to a strain cultivation equipment, in particular to an automatic koji seeding machine. Background technique [0002] Aspergillus is an important strain in the fermentation industry and food processing industry, and can be used to make sauce, wine, and vinegar. Aspergillus culture needs to be carried out in a sterile environment, often in a sterile room. However, even in a sterile room, due to repeated entry of staff, certain bacteria will still be carried, which affects the quality of Aspergillus culture. In addition, Due to the large space and volume of the sterile room, it is difficult to stabilize the temperature, humidity and air flow in the room at the same level. Secondly, the steps of inoculation on the culture medium are all manually operated, and the low efficiency leads to There are deviations in the cultivation progress of Aspergillus, and finally, the transportation of Aspergillus after the cultivation is completed al...
