USDA Dairy Accepted Airlock for Hygienic Applications
The Global Hygienic Airlock (GHA)
is a USDA Dairy accepted dismountable airlock that is ideal for applications
where dry raw or finished products are being handled in the process and where
inspection or system clean-out are required.
Because the GHA is designed for high process rates it possesses a number
of features suited to processes that have a higher sanitary requirement.
The Global Hygienic Airlock (GHA)
is a USDA Dairy accepted dismountable airlock that is ideal for applications

Because the GHA is designed for high process rates it possesses a number
of features suited to processes that have a higher sanitary requirement.
The round inlets and
outlets of the GHA incorporate seals and product contact surfaces that meet
food safety requirements. FDA and EC
1935/2004 approved materials are used in the product contact areas. Endplates and the rotor can be disassembled
and removed from the valve housing for cleaning. All endplates have specifically been designed
for access to the seal area for cleaning or seal replacement. Upon reassembly, the rotor end clearances can
be adjusted and set through by use of the integral adjustment screws included
in each endplate.
A unique feature of
the GHA is the rail system consisting of externally mounted precision shafts,
which are fixed to the tail side endplate on one end and are supported by
special composite linear bearings pressed into the valve housing on the other. The endplate/rotor assembly can be unbolted
from the housing and the assembly can be pulled from the housing and drive
coupling while still remaining rigid to the housing via the rail system. These features simplify removal and provide
access to the internal valve cavity, rotor pockets and all other product
contact areas for quick and easy cleaning. Once the cleaning process is
complete, the endplate/rotor assembly simply slides back into place through use
of the rail system and is secured with the supplied fasteners.

The GHA comes equipped with a Valve Interference Detection (VID) system that is designed to protect the airlock from damage and prevent product contamination due to interference between the valve rotor and housing. The VID system employs ceramic bearings and other innovative techniques to electrically isolate the moving rotor from the valve housing and drive system. A simple electronic evaluation unit monitors the resistance between the rotor and housing allowing it to determine if the circuit is functioning properly and if the rotor is contacting the housing.
With a number of features designed to meet hygienic process requirements along with acceptance by the USDA Dairy Grading Branch the new GHA serves as an integral component to systems designed for sanitary applications.
