2.8.4 CONNECTION TO UTILITIES AND PRODUCT LINE
The type, dimension and position of the connectors normally used to connect
the machine to the production line are specified in the dimension drawing in
Section 1 – TECHNICAL SPECIFICATIONS.
The machine also includes (section 1 – TECHNICAL SPECIFICATIONS):
- water connection for lubrication of packs and cooling (max. hardness 8 °dH /
15 °fH; recommended chloride value < 25 mg/liter, max 200 mg/liter
- water drain pipe;
- (possible) connection for compressed air (for homogenizers provided with air-
operated control system);
- (possible) connection for steam (for aseptic versions)
- condensate drain from lubrication system;
- discharge grid for cooling air.
For the specific requirements of each machine, type of connections and fluid
specifications, please refer to Section 1 – TECHNICAL SPECIFICATIONS.
As far as the utility connections, we recommend providing on/off solenoid valves
designed to open at the machine start (if not already included in the machine) to
be placed at the machine’s utilities inlet ports.
In particular, the manual valves of the lubrication water circuit should remain
always open, in a position which allows controlling an adequate flow of water for
lubrication or production of enough condensate (for the aseptic version).
Keep in mind that excessive lubrication water can lead to flooding of the sump
where water is collected, with the risk of water going into the drive section and
polluting the lubrication oil; for this reason it is important to regularly drain any
condensate or water that may be found in the lubrication circuit, as described in
Section 4 - MAINTENANCE.
WARNING: For the machines provided with aseptic system, the Customer
shall be responsible to install a steam pressure reducer to protect the
aseptic system and ensure operators’ safety. Fluid specifications are
shown in Section 1 – TECHNICAL SPECIFICATIONS.
In case a pipe is used for the water drainage, when calculating the required
diameter and slopes, remember that water is discharged by gravity and not by
pressure. Provide an adequate degree of slope in the system to avoid water to
accumulate in the sump.
WARNING: For the disposal of waste water or cooling water, refer to the
specific regulations in force locally. No traces of lubrication oil or product
residues are allowed in the effluents disposed.
