Description

Pilot plant seed fermentation cylinder

Technical Field

The utility model relates to a fermentation device.

Background

According to CN201120531789.5, the name of the patent is pilot scale type biological fermentation inoculation and transfer equipment, the sealing effect and parameter adjustment are inconvenient, and with the development of the biological fermentation technology, more and more fermentation products are slowly expanded from a laboratory to large-scale production, wherein the pilot scale stage is an essential process. Microbial fermentations are typically started from laboratory shake flask fermentations. The main effects are two, and firstly, proper and high-yield strains are screened; secondly, finding out a proper culture medium formula and a preliminary fermentation condition. The pilot test is prepared for future large-scale production, and provides accurate process parameters and design basis for large-scale production, so that the pilot test cannot be omitted, and the selection of pilot test equipment plays a crucial role in whether large-scale production can be expanded or not. There are significant drawbacks to the prior pilot seed fermenters: 1. the culture and fermentation environments of the strains from the laboratory to the pilot-scale test stage are greatly different, and the key for success of the test is to ensure that the strains are not infected by other mixed bacteria in a fermentation period. The prior pilot plant can not be infected with bacteria in a short time, but cannot be infected with bacteria in a long time. 2. The parameters of temperature, pH value, dissolved oxygen, stirring speed and the like are difficult to control in the fermentation process, and the parameters are necessary to provide for the scale-up production of the fermentation.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

The present invention will be further explained with reference to the accompanying drawings.

Referring to the attached drawings 1-2, a pilot plant seed fermentation tank comprises a tank body 1, wherein an instrument interface 2 is arranged on the outer wall of the tank body 1, an equipment flange 3 is arranged on the outer wall of the tank body 1, a sealing element is arranged in the equipment flange 3, a magnetic stirring element 4 is arranged on the outer surface of the tank body 1, an aeration head 5 is arranged on the lower side surface of the tank body 1, a tank bottom valve 6 is arranged at the lower end of the tank body 1, a steam sterilization machine is arranged in the tank bottom valve 6, an instrument interface 2 is provided with a sampling valve interface, a sampling valve is inserted in the instrument interface 2, a thermometer interface is arranged in the instrument interface 2, a thermometer is inserted in the instrument interface 2, a PH/DO electrode is inserted in the instrument interface 2, the sampling valve interface and the sampling valve are electrically connected, the thermometer interface and the thermometer interface are electrically connected, and the PH/DO electrode interface and the PH/DO electrode are electrically connected.
