Description

Technical Field

[0001] The invention relates to the technical field of pet food processing, in particular to complete pet food processing equipment. Background Art

[0002] A fermentation tank is a device specially used for microbial fermentation in bioengineering related industries. Especially in the field of pet food processing, the application of fermentation tanks is indispensable. Due to the different styles of food processing, different types of stirring blades are required for stirring different foods. For example, the blades of the parabolic disc turbine are parabolic, with extremely strong radial displacement and dispersion capabilities. At the same power, its mass transfer coefficient is more than 30% higher than that of the straight blade disc turbine, and the gas holding capacity is increased by more than 40%, and the power consumption ratio is very low. Therefore, it is particularly suitable for dissolved oxygen operations similar to fermentation processes, and is also suitable for gas dispersion, absorption, mass transfer and heat transfer operations under other requirements. The three-blade propulsion type has high liquid discharge and low shear performance: the use of baffles or guide tubes makes the axial circulation stronger, and the discharge performance is significantly improved. Its strong circulation capacity and low power consumption can best reflect its advantages in large-capacity homogeneous and mixing processes, and in low-viscosity liquid heat transfer, reaction, suspension and dissolution with a small solid-liquid ratio.
