A Zhongshengmycin fermentation continuous feed production device and production method thereof

Abstract

The invention discloses a zhongshengmycin fermentation continuous feeding production device and a production method thereof. A feeding medium in a zhongshengmycin fermentation process is not subjected to steam high-temperature moist heat disinfection and sterilization; the feeding medium is equipped with a conveying system, a flow meter for measurement and a sterilization filtering system to obtain a sterile feeding medium which is continuously added into a fermentation tank, so that zhongshengmycin fermentation is continuously and normally performed; and the sterilization filtering system realizes disinfection and sterilization and pressure maintaining at the time of the disinfection and sterilization of a fermentation medium in the fermentation tank. In the invention, the labor intensity of workers is greatly relieved, the feeding control in the zhongshengmycin fermentation process is more flexible and accurate, the steam is remarkably saved, and the fermentation production level of zhongshengmycin is improved. The zhongshengmycin fermentation continuous feeding production device and production method thereof disclosed by the invention are not reported yet.

Description

Technical field [0001] The invention relates to the fermentation production of biological pesticides, in particular to a zhongshengmycin fermentation continuous feed production device and a production method thereof. Background technique [0002] According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), in the process of agricultural and forestry production in the world, the annual losses caused by diseases, insects and weeds are more than one-third. Approximately 3 million chemical pesticide poisoning incidents occur worldwide every year. In developing countries, there are approximately 1,650 collective poisoning incidents caused by the consumption of pesticides contaminated food every year. Therefore, it has become an inevitable trend and a global consensus to vigorously develop safe, low- and non-toxic, low-accumulation and no-accumulation biological pesticides that do not pollute the environment. Zhongshengmycin is a new type of agric...

AI Technical Summary

Problems solved by technology

[0005] 1. The current feed medium adopts the well-known damp heat sterilization method in the industry. Since the damp heat sterilization needs to reach 121°C and the sterilization maintenance time is 30 minutes, the high temperature process of the feed medium above 80°C takes as long as 60 Minutes or more, causing the appearance of the feed medium to turn red or brown after a long period of high temperature, the nutrients in the feed medium are destroyed, and even produce substances that are toxic to the Zhongshengmycin-producing bacteria, affecting the Zhongshengmycin Increased fermentation level

[0006] 2. The current feeding process is intermittent large-scale feeding, which causes large fluctuations in the composition of the medium in the fermenter, which has a great impact on the micro-growth environment of the Zhongshengmycin-producing bacteria, which is not conducive to the growth and secondary production of the producing bacteria. growth of metabolites

[0007] 3. The current fermentation process intermittently feeds a large amount of materials, which is easy to form the well-known glucose effect in the industry, resulting in the inhibition of the formation of secondary metabolites and affecting the growth of Zhongshengmycin production

[0008] 4. The current intermittent large-scale feed makes the nutrition excess in the early and mid-term of fermentation, and a large number of bacterial cells multiply; the nutrition in the middle and late stages is insufficient, which cannot further improve the fermentation level of Zhongshengmycin, and the content of Zhongshengmycin in the fermentation liquid hovers at 8.00g / L— Between 10.00g / L

[0009] 5. The current intermittent large-scale feeding process needs to consume a large amount of steam for multiple feeding medium disinfection and multiple feeding pipeline disinfection, which results in high labor intensity for employees and a large amount of energy consumption
