What are the basic conditions of stainless steel fermenter?

Customer Question: What are the basic conditions of fermenter?

A: Basic conditions of fermenter mechanical stirring Fermenter is the use of mechanical stirrer to make air and fermentation liquid fully mixed, promote the dissolution of oxygen in the fermentation liquid, so as to ensure the supply of oxygen required for microbial growth, reproduction and fermentation.

First, the use of fermenter tips

1. It is necessary to ensure the normal operation of all single equipment when using this system.

2. When disinfecting the filter, the steam pressure through the air filter shall not exceed 0.17MPa, otherwise the filter element will be damaged and the filtration ability will be lost.

3. In the fermentation process, the tank pressure should not exceed 0.17MPa.

4. In the actual consumption process, when the jacket is preheated by steam, it is necessary to control the intake pressure within the working pressure range of the equipment, otherwise it will cause damage to the fermenter.

5. When emptying and emptying, the remaining water in the fermenter jacket must be drained. Otherwise, it may cause the cylinder inside the tank to be flattened, resulting in equipment damage; When actually consumed, too much condensate will form, causing the culture solution to dilute and then fail to meet the skill requirements.

Two, fermenter protection

1. Fine filter, the general service life is half a year. If the filter resistance is too large or the filter element is lost and affects the normal production, it needs to be cleaned or replaced (advocate direct replacement, not cleaning, because the cleaning can not reliably ensure the performance of the screen).

2. When cleaning, please rinse with a soft brush and do not scrape with a hard device to avoid damage to the surface.

3. The supporting appearance should be checked once a year to ensure normal use.

4. Do not allow electrical appliances, appearance, sensors and other electrical equipment to contact water vapor directly to avoid moisture.

5. When stopping use, it should be cleaned in time to discharge the remaining water of each pipe; Loosen the lid and hand hole screws to avoid long-term deformation of the seal ring.

6. Carbon steel equipment such as fermenter operation channel and constant temperature water tank should be painted regularly (once a year) to avoid corrosion.

7. Check the oil level of the reducer often. If the lubricating oil is not good, it needs to be increased in time.

8. Replace lubricating oil of reducer regularly to extend its service life.

9. If not used for the time being, empty and drain the remaining water in the tank and pipe.

What are the applications of fermenters?

Customer Question: What are the application areas of fermenter?

A: Fermenter is mainly used in dairy fermentation, beer fermentation, wine fermentation, kitchen waste treatment equipment, food waste water treatment, winery waste water treatment equipment, biogas fermentation equipment and other fields.

First, the engineering application of fermenter

1. Application in the pharmaceutical industry: According to the technology of fermentation engineering, a wide variety of drugs have been developed, such as human growth hormone. Recombinant hepatitis B vaccine. Certain monoclonal antibodies. Interleukin-2. Antihemophilia factor, etc.

2. Application in food industry: there are mainly three kinds of commodities, one is the production of traditional fermented commodities, such as beer, fruit wine, vinegar, etc.; Second, the production of food additives; Third, help solve the food problem.

3. Use in the category of environmental science: strengthening of microorganisms in sewage treatment.

Two, fermenter of two operating forms

Normal cultivation form and sterilization form. Under normal conditions, the pressure is controlled at 200kPa, stirring to 120r/min. Temperature control refers to the water in the sandwich through the circulating pump, through the cold room, heat exchange plate, control system temperature. The disinfection method was to carry out DI water circulation in thigh exercise with sandwich circulation pump. The water was sent into the sandwich through the heat exchange plate, so that the medium in the tank was heated up to 121℃ and held for 30min. Then, the temperature of the fermenter was lowered through the cold exchange plate, and the cooling air in the tank was supplemented with the sterilizing filter.
