7.4 Automatic timed processes
Recirculation and stirring are two timed processes, activated automatically to properly store
the product in the canisters and keep it in ideal, homogeneous conditions for dispensing.
The times regulating these processes may be set via the configuration program (see the
CorobTECH program user's manual) depending on the physical nature of the colorants used on
the machine.
Recirculation and stirring may also be activated directly by the operator whenever necessary.
The Recirculation process consists of activating the pumps at high speed to draw the colorant
out and return it to the canisters; the colorant leaves the bottom of the canister and returns in
the canister through the recirculation connector, without being dispensed through the nozzle
center.
This process circulates the colorant through the dispensing circuits, avoiding pigment
sedimentation in the various parts of the circuit.
The Stirring process consists of activating the stirrers located inside the canisters, one after
another, beginning with the one inside the first canister; the stirring process ends when the last
canister has been stirred. The movement of the stirrers keeps the colorant in the canisters
homogeneous.
Stirring also serves to prevent the precipitation of pigments, flocculation and sedimentation of the
colorants in the canisters.
The rotation speed of the stirrers prevents the formation of air emulsions and other negative
effects that could interfere with the machine's performance.
Keep the canisters closed with their corresponding lids, and do not insert hands in the
canister even when no colorant is present.
The stirring and recirculation times set via the application program are sent to the machine
during initialization; the timed processes are active even if the machine is turned on without the
computer.
