Internal washing provisions for food process line machines

An improvement for a food process-line coating machine in an automatic mechanized food-process line and which food process-line coating machine coats a stream of food product with a dry-particulate coating material between an upline machine and a downline machine in said automatic mechanized food-process line, said food process-line coating machine comprising:

• an intake conveyor having an upper food-product carrying run and a lower return run, and extending between an intake end that intakes a food product stream from the upline machine in said automatic mechanized food process-line and a discharge end that discharges the food product stream either to a direct destination within said food process-line coating machine or else to the downline machine;
• an overhead coating material dispenser of coating material onto underpassing food product on the food-product carrying run of the intake conveyor;
• and
• when the intake conveyor discharges the food product stream to the direct destination with said food process-line coating machine, the direct destination have an input end and an outflow end, said food process-line coating machine further comprising an outflow conveyor having an upper food-product carrying run and a lower return run, and extending between a receiving end that receives the food product stream from outflow end of the direct destination within said food process-line coating machine and a discharge end that discharges the food product stream to the downline machine in said automatic mechanized food-process line;
• said improvement comprising:
• a permanently-installed internal cleaning-fluid circuit and at least one internal cleaning-fluid distribution device in said food process-line coating machine;
• said food process-line coating machine being operable in one exclusive state comprising coating operations and another exclusive state comprising cleaning operations;
• and
• said food process-line coating machine being switchable between the exclusive operable states, from the coating operations operational state to, but not concurrently operable with, the cleaning operations operable state, and switchable back and forth indefinitely, whereby the exclusive operable states being switchable whether by human operators or other.
