The liquid fermentation tank manufacturer will introduce the cooling system of the fermentation tank to you

Liquid fermentation tank manufacturer: The fermentation tank is cooled by an industrial water cooler

The method of cooling these chambers is different from the fermentation container itself, and these freezing methods can be carried out from both the internal and external directions.

Cooling from inside

Some fermentation cooling devices require inserting a cooling rod or a loop into the fermentation broth, and these devices increase the risk of cooling the fermentation container from the inside by directly contacting the coolant. If tools and equipment are inserted into the fermentation broth at any time, they may come into contact with unwanted microorganisms such as wild yeast, which may change your preferences and bacteria, contaminating your beverage, Opening the fermentation chamber and inserting a cooling device can also increase oxidative degradation changes.

Even with this cooling method, the cooling efficiency will be significantly reduced, and the fermentation broth will be exposed to a smaller cooling surface area, resulting in poor cooling effectiveness. Especially with a large amount of fermentation broth, the risk of hot spots and cold spots in the fermentation broth will increase, making it difficult for yeast to complete the fermentation process.

Cooling from outside

Cooling the fermentation chamber from the outside is the most effective method. Regardless of the diameter of the fermentation container, the external surface area is always larger than the internal cooling, making direct contact between the freezing source and the fermentation container the best effect. Due to the uniform heat flow from the container to the cooler, the fermentation tank has a variety of shapes and sizes, so in order to fully contact the container, the cooling source must be as flexible as possible.

Coolant

The fermentation cooling jacket completely wrapped around the fermentation tank provides the most direct cooling contact. The insulated magnetic flux jacket from our company's water chiller has multiple coolant channels that are evenly distributed around the fermentation chamber. These temperature adjustment ranges can remove hot and cold spots, maintaining the mood and fermentation of the yeast. The air-cooled water chiller is easy to install, without opening the fermentation container, and can flexibly handle the shapes and sizes of various containers.

Liquid fermentation tank manufacturer: How to mix materials in a fermentation tank

By mechanically stirring the materials in a fermentation tank, axial and radial flow is generated, which allows the materials in the tank to mix well, keeping the solid substances in the liquid in a suspended state, facilitating full contact between the solid and nutrients, and facilitating nutrient absorption; On the other hand, it can crush air bubbles, increase the gas-liquid contact area, improve the transmission speed between gas and liquid, improve the transmission effect of oxygen, and eliminate air bubbles. At the same time, it is necessary to inject sterile air to maintain the oxygen in the cell to meet the growth and fermentation of aerobic bacteria.

The structure of the fermentation tank is characterized by the rapid rotation of the rotor immersed in the fermentation liquid. Due to the centrifugal force, the liquid and air move towards the outer edge, and the pressure near the rotor gradually increases. Therefore, the rotor of the fermentation tank rotates faster. Due to the gap between the rotor and the atmosphere, the air outside the fermentation tank is constantly sucked in through the filter, and soon is thrown towards the outer edge of the impeller. Then, the air and liquid are evenly distributed through the anisotropic impeller, resulting in stirring, It also makes the gas and liquid form a strong mixing flow around the impeller, the air foam is crushed, and the gas and liquid are fully mixed.

Through the introduction above, we all have a new understanding of fermentation tanks. If you have any other questions, they can relate to our liquid fermentation tank manufacturer. Okay, liquid fermentation tank manufacturer wishes everyone a happy life
