Water storage tanks:
In Cleaning & sanitizing, water storage tanks are emptied on
ce in two months, scrubbed from inside with sodium bicarbonate and sanitized with chlorine solution of 200PPM. Finally, tanks are cleaned with fresh water.
Bottle Washers (80 BPM washer)
Strainers are removed daily and all the dirt is cleaned by forcing water and then put back in the position. All the jets in the compartments are checked daily and pinned if necessary.
Draining of final and prefinal rinse of compartments is done before cleaned and fresh water is taken daily before the start of the production. Caustic solution in the first and second compartments is drained by opening the drain valve once in a week. Compartments are cleaned with water using a brush and then fresh water and caustic is taken in the compartment for further use.
In Final rinse compartment sanitation the compartment is filled with 100 PPM chlorine solution once in a fortnight. The pump is kept running for about 20 minutes following which the chlorine solution is drained out and fresh water is used for rinsing the compartment.
Cleaning & Sanitation: 50 to 75lts of detergent is prepared in the cooler tank and solution is pumped into the carbonator and filled. Then solution is drained out through the fillers. After cleaning the detergent solution, water is passed through the equipment. Then about 80lts of chlorine solution of 150Pm is prepared and the filtered solution poured in the cooler tank. The solution is pumped into the carbonator and then drained out through the fuskies. Finally the above system is rinsed with fresh water till the chlorine disappears.
Dismantling & sanitizing the carbonator is another procedure. Here, the cover of the carbonator is opened and all the plates are removed. Plates and shell are then cleaned with detergent solution followed by water. The chlorine solution of 150 PPM is prepared and used for sanitizing the plates and the shell. Finally, they are rinsed with fresh water till chlorine disappears, the carbonator plates are rearranged as before and the cover is fitted on the back.
Proportionating Unit, Chiller, Carbonator & Filler (Premix System)
Cleaning in Place (CIP): The equipment be flushed with water and sanitized with chlorine solution as per the schedule in accordance with the laid down procedure. As per the procedure, CO2/ air counter pressure from the carbonator is released and beverage/ syrup is drained from the entire system of bottling equipment at the drain points provided. The flush operation is started after draining is completed by flowing clean water through both syrup and beverage systems. All the equipment need to be flooded to allow water to bleed out of the air vents. Filler is started to allow several revolutions to open and close the filling valves as the flushing water flows through (run the filler with washed bottles).
All equipment are drained from the drain points and after making sure that drain valves are closed, the equipment is flooded with the sanitizing agent (150 ppm Cl2 solution) in a similar manner as that is done with fresh water. A contact time of minimum 15 minutes is allowed. All the equipment are drained through the drain valves, except the filler, which revolves and drains the sanitizing agent through the filling valves (rush filter with washed bottles). Flushing operation has to be carried out using fresh water to thoroughly wash off the sanitizing agent from the entire system.
This cleaning/sanitizing in place should be carried out minimum once a day after the day’s production. This operation is started as soon as the proportioning system is emptied without waiting for the closure of production as this saves time of cleaning operation.
Hot detergent sanitation in place
The procedure for carrying out hot detergent sanitation is similar to that of chlorine sanitation. The hot detergent is prepared in the syrup tank and heated to around 95oC. It is then passed through all the equipment and after a contact time of half an hour at around 80o to 85oC, it is drained and flushed with fresh water. Hot detergent sanitation is recommended to be carried once a week.
The Dismantling and cleaning process entails that all the equipment should be completely dismantled, washed & scrubbed with the detergent paste once a week. Suitable brushes scourers should be used to enable proper cleaning. All the equipment are reassembled and cleaning is carried using chlorine as the sanitizing agent. It is preferred to carry out the sanitation with cl2 after cleaning with detergent in place. The detergent used is a 2.5% solution made out of a mixture of soda ash and tri-sodium phosphate in the ratio 850:150 gms. While sanitizing the filler, empty washed bottles is passed through it for at least two rounds each, with water and cl2 solution. In case the plant is closed, 10 ppm cl2 solution is kept in the lines and equipment overnight. The traces of cl2 should be completely removed from the system just before starting the plant.
Hot detergent sanitation involves removing the temperature sensing bulb Taylor controller / recorder from the system and plugging this outlet with suitable device. In case, direct expansion type chiller is used for beverage chilling, the systems need to be pumped down before carrying out hot detergent sanitation. In case of boilers, the burner is removed and cleaned once in three days. The backside and front portions are opened and using a long brush, the carbon accumulated inside the tubes is removed.
For cleaning Cooling Tower or Spray Pond, the water must be drained out completely. All the soil and algae growth are removed and cleaned with water and bleaching solution using a wire brush.
