What is the beer fermenter of Beer Equipment?

  There are many, many different types of brewing equipment that go into craft beer and beer making, and one of them is the beer fermenter.

  beer fermenter is an industrial device used for microbial fermentation. Its main body is generally made of stainless steel plate main cylinder, its volume in 1m to hundreds of m. In the design and processing should pay attention to the structure of strict, reasonable.

  It can withstand steam sterilization, has certain operating flexibility, reduce internal accessories as far as possible (avoid dead corners), strong material and energy transfer performance, and can be adjusted to a certain extent in order to clean, reduce pollution, suitable for the production of a variety of products and reduce energy consumption.

  The beer fermenter produced by the Power Age craft Beer Equipment is mainly made of copper or stainless steel fine workmanship, and the appearance is elegant and elegant.


  beer fermenter used for anaerobic fermentation (such as the production of alcohol, solvents) can be relatively simple in structure. beer fermenter used for good gas fermentation (such as the production of antibiotics, amino acids, organic acids, vitamins, etc.) needs to continuously inject a large amount of sterile air into the tank, and in order to consider the utilization rate of the air, so the structure of beer fermenter is relatively complicated. Commonly used are mechanically stirring beer fermenter, bubbling beer fermenter and air-lift beer fermenter.

  The fermentation process of dairy products and wine is a sterile and pollution-free process. beer fermenter adopts a sterile system to avoid and prevent the pollution of microorganisms in the air, which greatly extends the shelf life of products and the purity of products. The tank body is specially designed and installed with sterile breathing holes or sterile positive pressure fermentation system. The tank body is provided with a Milo plate or labyrinth type jacket, which can be fed into the heating or cooling medium for circulating heating or cooling. beer fermenter's capacity ranges from 300 to 15000L in a variety of different specifications. According to the scope of use, beer fermenter can be divided into small laboratory beer fermenter, pilot production beer fermenter, large beer fermenter, etc.

  beer fermenter is widely used in dairy products, beverage, biological engineering, pharmaceutical, fine chemical industry and other industries. The tank body is equipped with sandwich, insulation layer, heating, cooling, heat preservation. The tank body and the upper and lower filling head (or cone) are processed by spinning R Angle, the inner wall of the tank is polished by mirror, there is no sanitary dead Angle, and the fully closed design ensures that the materials are always mixed and fermented in a pollution-free state. The equipment is equipped with air breathing hole, CIP cleaning nozzle, manhole and other devices.

  Classification of beer fermenter: according to the equipment of beer fermenter, it can be divided into mechanical stirring ventilated beer fermenter and non-mechanical stirring ventilated beer fermenter;

  According to the needs of microbial growth and metabolism, beer fermenter and anaerobic fermentation irrigation were divided into two types.

  beer fermenter is a machine for mechanically stirring and fermenting materials. The equipment adopts internal circulation mode, dispersing and breaking bubbles with stirring paddle, which has high oxygen dissolution rate and good mixing effect. The tank is made of SUS304 or 316L imported stainless steel. The tank is equipped with automatic spray cleaning machine head to ensure that the production process meets the GMP requirements.

  Structural characteristics:

  1. On-line CIP cleaning and SIP sterilization (121°C/0.1MPa).

  2. It is designed according to the requirements of sanitary grade, and the structure design is very humanized and easy to operate. Smooth transmission, low noise.

  3. Suitable diameter to height ratio design, customized stirring device, energy saving, good mixing and fermentation effect.

  4. Mirror polishing of inner tank surface (roughness Ra≤0.4m); The opening of each inlet and outlet pipe, sight mirror, manhole and other process and the welding of the inner tank body adopt the arc transition of the drawing flanging process, smooth, easy to clean without dead Angle, to ensure the reliability and stability of the production process, in line with the requirements of "cGMP" and other specifications.

  Main components:

  Tank body: mainly used to culture and ferment all kinds of bacteria, good sealing (prevent bacteria from being polluted)

  The tank contains a stirring paddle, which is used to stir continuously during the fermentation process

  A bottom-vented Sparger that lets in the air or oxygen needed for cell growth

  The top plate of the tank has a control sensor, the most commonly used pH electrode and DO electrode, used to monitor the fermentation liquid pH and DO change controller, used to display and control fermentation conditions and so on.

  How to use:

  1) Correct pH electrode and dissolved oxygen electrode.

  2) Sterilization of tank. The medium was added into the tank as required, and after sealing according to the requirements, the small beer fermenter (5L) could put the tank into the large sterilization pot for sterilization (115℃, 30 minutes); Large beer fermenter (10L and above) was steam sterilized (121℃, 30min).

  3) After cooling the tank, place it on the fermentation table and install it well; Open the cooling water, open the air pump power supply, connect the ventilation pipe to start ventilation, adjust the intake knob to make the ventilation appropriate, so that tank pressure is maintained at 0.05MPa; The temperature, pH and stirring speed were set, and the slope of the dissolved oxygen electrode was calibrated at the determined speed and ventilation rate. The value was 100%

  4) After the temperature is stable and all parameters are correct, the pre-shaken seeds are added, the fermentation time is started, and various parameters are recorded.

  5) After fermentation, clean the tank and electrode, insert the pH electrode into the triangle bottle with 3M potassium chloride for use, cover the probe of dissolved oxygen electrode with protective condoms, and save for later.

  Additional devices:

  * Blender (multistage or infinitely variable speed). Sterile breathing hole (or sterile positive pressure device)

  * Inlet and outlet. Sterile sampling outlet

  * Manhole. Cold and hot water inlet and outlet

  * Thermometer.CIP Cleaning spray head


  1, such as the air inlet pipe and outlet pipe joint leakage, when tightening the joint does not solve the problem, should add or replace the filler.

  2, pressure gauge and safety valve should be checked regularly, if there is a fault to be replaced or repaired in time.

  3, when cleaning beer fermenter, please use a soft brush to scrub, do not use a hard machine to scratch, so as not to damage the surface of the beer fermenter.

  4, supporting instrument should be checked once a year, to ensure normal use.

  5. Electrical appliances, meters, sensors and other electrical equipment are strictly prohibited from contact with water and steam directly to prevent moisture.

  6. When the equipment stops being used, it should be cleaned in time to exhaust the remaining water in the beer fermenter and the pipes; Unscrew the beer fermenter can lid and hand hole to prevent permanent deformation of the seal ring.

  7. Carbon steel equipment such as operating platform and constant temperature water tank should be painted regularly (once a year) to prevent corrosion.

  8. Check the oil level of the reducer frequently. If the lubricating oil is not enough, it needs to be increased in time.

  9. Replace lubricating oil of reducer regularly to prolong its service life.

  10. If the beer fermenter is not used for the time being, it is necessary to empty out the beer fermenter and exhaust the remaining water in the tank and the pipes.


  1). Before sterilizing the tank, it is necessary to check the liquid level, and all electrodes are required to be below the liquid level.

  2). Before turning on the beer fermenter power supply, make sure that the cooling water is turned on and the temperature probe is inserted into the slot, otherwise it will burn out the heating circuit.

  3). The fermentation process must keep the table clean, used culture bottles and other items in time to clean, for reasons spilled acid lye or water should be immediately dry.

  4). Special care should be taken when installing, disassembling, and sterilizing the pH electrodes and vulnerable and expensive parts of the tank.

  Structure composition:

  beer fermenter is widely used in beverage, chemical, food, dairy, seasoning, brewing, pharmaceutical and other industries, plays the role of fermentation. The components of beer fermenter include: the tank is mainly used to culture and ferment all kinds of bacteria, with good sealing (to prevent bacteria from being polluted), and there is stirring slurry in the tank, which is used to stir continuously during the fermentation process; The bottom has a ventilated Sparger, which is used to pass the air or oxygen needed for the growth of the bacteria. The top plate of the tank has a control sensor. The most commonly used are pH electrode and DO electrode, which are used to monitor the change of pH and DO in the fermentation liquid during the fermentation process. The controller is used to display and control fermentation conditions. According to the equipment of beer fermenter, it can be divided into mechanical stirring ventilated beer fermenter and non-mechanical stirring ventilated beer fermenter.
