Finish the season off right

Posted on 30 April 2020

Leave your milking plant clean and sanitary, so you can hit the ground running next season.

Cows always seem to start calving earlier than planned, which often means you don‘t get the chance to clean your plant properly. To ensure you are not left with unwanted protein build-up next season, it is essential that you leave your milking plant clean and sanitary.

 
Recommended steps to follow:

1. LAST WASH

The last wash should be a very strong alkali at 85°C, recycled for 5-8 minutes and then dumped at around 60°C.

a. Stand and observe that the flushing pulsator is working well. It should still be going as the slug hits the receiving can. (If not it needs adjusting before next season).

b. If you have signs of cleaning issues after the alkali wash, use a milking line brush (with filter sock on) down the line to remove any remnants.

c. Then do a final rinse with your normal acid wash.

d. Follow the same procedure for the bulk milk tank. The vat is then ready for the new season.

DO NOT ENTER the bulk milk tank - this is classified as a confined space.

 

2. PULSATORS AND VACUUM LINES

Inspect the pulsator line and vacuum lines, if these need cleaning do it now. Leaving until next season will make them very difficult to clean.

a. Pulsators should be removed and the holes blocked.

b. An alkali should be sucked through the line from each end.

c. Ensure you brush the line if required.

 

3. LINERS AND RUBBERWARE

Liners and rubberware that need replacing should be removed at this stage. It is best practice to replace liners every 2,500 milkings.

a. Remove air tubes, milk tube and claw tubes and inspect for deterioration. You can soak these in a solution of alkali. Otherwise, new rubberware should be ordered at this point.

b. After a couple of days remove and rinse thoroughly.

c. You should also clean teat cup shells at this stage.

 

4. MILK DELIVERY LINE AND SEALS

Take some time to inspect the milk line unions and the milk delivery line joins in the plant.

a. Your local GEA FIL Area Manager will have an inline camera that can be used to inspect the milk line and check milk line union seals, as these can quite often be frayed.

b. It’s a very big job to take the milk line apart to inspect them. It’s far easier doing it with a camera.

c. Take the inlet and outlet off the vat - ensure you check these seals also.

 

5. JETTER LINE

An area that is always over looked is the jetter line. If you have the external rubber cups that the inflations fit up into, these need to be checked for splits and replaced. If they are split it slows the water flow down.

 

6. MACHINE TESTING

Book a machine test with your local dealer. Ensure the plant is back together with all the new rubberware before this is done.

a. Get the dealer to replace the seal that is behind the milk pump impeller, this needs to be done annually and is a big contributor to milk quality issues.

 

IMPORTANT POINTS:

1. Take time to listen for any sucking noises around your plant. Any air leaks could compromise a thorough and efficient wash.

2. Get your technician in during the dry period to fix any faults you notice on the last wash, as technicians are typically busy early-season.
