Abstract
Described herein is an improved homogeniz head in which a variable orifice can be readily provided. The head (10) comprises a casing section (12) and a plug section (14). The casing section (12) has an internally threaded portion (120) which has a series of notches (126) formed in the threads (124). The plug section (14) has an externally threaded portion (14) which has a series of flats (154) formed on the threads (152). The two threaded portions (120, 140) are engaged and the cooperation of the notches (126) and flats (154) define homogeniz orifices through which the material being homogeniz passes. The orifices so formed are variable in size depending on the relative positioning of the notches (126) relative to the flats (154).
Claims18
An apparatus for homogenizing a liquid comprising:
- a casing portion having an inlet port, an outlet port and at least one internally threaded portion situated between the inlet port and the outlet port;
- a plug portion having at least one externally threaded portion for engaging the at least one internally threaded portion, the plug portion being rotatable relative to the casing portion and being threadably engaged with the casing portion to yield at least one threadably engaged section,
- a channel defining means for defining at least one homogenizing channel across the at least one threadably engaged section, the channel defining means comprising at least one first region formed in the internally threaded portion and at least one second region formed on the externally threaded portion, the at least one first region cooperating with the at least one second region in the at least one threadably engaged section such that through rotation of the plug portion the at least one homogenizing channel can be varied between a fully open position and a fully closed position.
