'''Direct-drive type:''' The motor drives the crankshaft to move the plunger back and forth and directly pressurize the material. Multiple sets of plungers provide constant pressure, and the flow rate is high for this type of homogenizer. However, the minimum material requirements are also high, as is the amount of residual produced. The crankshaft driven by the motor needs a multi-stage gear reduction mechanism, which limits these homogenizers to only moderate efficiency and requires large unit dimensions. This homogenizer type is suitable for the food and chemical industries, as well as other applications that do not have high pressure requirements. | '''Direct-drive type:''' The motor drives the crankshaft to move the plunger back and forth and directly pressurize the material.

Intensifier type: The intensifier-type homogenizer is the result of the development of ultra-high pressure technology in recent years. One of its mechanisms involves the motor driving the oil pump to pressurize the material through the hydraulic system. The pressure provided by the hydraulic system is higher than in direct-drive homogenizers, while the volume and the minimum material requirement is smaller. The intensifier-type homogenizer can be applied to both laboratory and production homogenizers with high pressure. Hydraulic homogenizers are expensive, but the hydraulic intensifier can achieve low-frequency and high-thrust piston movement, which increases the machine’s service life and reduces its maintenance costs. Using parallel four-cylinder technology, stable pressure can be obtained without an accumulator, achieving ultra-high pressure of up to 45,000 psi. | |||
