High pressure homogenizer and method for manufacturing graphene using the same

A high pressure homogenizer comprising

• a channel module which comprises a microchannel through which an object for homogenization passes,
• wherein the channel module comprises a front end channel for supplying the object to the microchannel, a back end channel in which the object passing through the microchannel flows into and at least one baffle disposed so as to partition the microchannel into a plurality of spaces,
• the baffle is provided so as to partition the microchannel into two spaces along the width direction or the height direction,
• the front end channel is provided so that at least a part of a flow area becomes small along the moving direction of the object and the back end channel is provided so that at least a part of a flow area increases along the moving direction of the object.
