1.0 Objective: To lay down the procedure for the operation and cleaning of the Index Type Rotary Bottle Washing Machine.
2.0 Scope: This Standard Operating Procedure for Bottle Washing Machine is applicable for the operation and cleaning of the Index Type Rotary Bottle Washing Machine in the liquid Oral department.
3.0 Responsibility:
Production Executive, Production Officer.
4.0 Procedure:
4.1 There are two water holding tanks: one for fresh water (Tank 1) and another for hot water (Tank 2) (Recycled water from the second wash).
4.2 The following sequence of washing is used for the washing of bottles:
FIRST CYCLE: Fresh Purified water (P. W.) from tank 1 – internal and external.
SECOND CYCLE: Hot P. W. (Recycled from 2nd Washes) from tank 2.
THIRD CYCLE: Fresh P. W. (Two Washes) from tank 1.
4.3 Affix the “UNDER PROCESS” label on the machine.
4.4 Fill purified water into tank no.1 by opening the valve on the Purified water line to the tank. Fill Purified water from tank no. 1 into tank no. 2 by means of a mug fill at least 3/4th of its capacity.
4.5 Enter starting time of bottle washing in the Equipment Usage Log Sheet as per “Making entry in equipment log sheet” SOP.
4.6 Put on the mains of the machine. Put the heater switch “ON” on the panel board in the ON position. Water in tank 2 starts getting heated. Set the thermostat to about 50°C.
4.7 Start both pumps: pumps 1 & 2 by pressing the respective green buttons. Check that water is coming out from all jets. If not, clean the jets and check again. Observe the pressure of the water jets on the respective pressure gauges provided. The pressure should be between 5 and 15 psi. as observed on the pressure gauge, (one gauge for each cycle). Operate the valves on these lines to get this pressure.
4.8 Keep the P. W. valve open in tank 1. The float valve provided in tank no.1, controls the water level. Let water after the second water wash gets collected in a tank no. 2. if necessary, add further fresh water into tank 2 to fill it, but put “OFF” the heater white adding the water.
