Technical tips

Checking the Astronaut milking robot

Daily check
The Astronaut milking robot should be checked daily for such things as the laser and the cords. A check only a few times per week is sufficient for the other components. Consult the user manual for the correctinstructions and intervals.

General functioning of the milking robot.
Check the number of milking sessions, refusals and failures. This information gives a reliable picture of the functioning of the Astronaut milking robot. Fore xample, it can be seen which cows are causing the failures.

Technical functioning of the milking robot
Check the average conductivity values, milking times, milking rates and DMT. These figures provide information on the technical functioning of the robot. Please be advised that all regular checks of the robot are listed in the Operators Manual.

Lely Consumables

Useful tips for maintenance and adjustment
Lely Consumables are exceptionally helpful products in achieving an optimum performance of your milking robot. Correct maintenance and adjustment of the associated equipment are crucial and that is why we would like to provide some useful information in this edition.

For a start, we would like to provide some general information about spraying udder care products. You are undoubtedly aware of the fact that there are many udder care products on the market. Most products are based upon three main components: chlorhexadine, lactic acid or Iodine. Quite often, another element - for instance glycerine - is added to soften the teat skin. In some cases perfumes such as peppermint or citronella are added to keep flies away, etc. Due to their individual product formula, there are large differences in the viscosity of various udder care products. Viscosity may also change under the influence of ambient temperatures.

We often establish that the original factory setting of the spray unit on the Lely Astronaut milking robot has remained unchanged. In addition, maintenance of this system is neglected by users in many cases. We therefore would like to provide some useful tips and hints aimed at increasing the overall performance of your spray unit. The pressure on the valve of the unit should be between 3 and 4 bar. A lower pressure is likely to produce too many droplets, whereas the product tends to dilute too much in the air with a higher pressure. The viscosity of fluids that are comparable to normal water requires a pressure close to 3 bar; the viscosity of fluids resembling engine oil needs a pressure close to 4 bar.

Correct maintenance of the spraying system is crucial. After every can, or at least twice a year, the system needs to be cleaned with only warm (tap) water with a temperature between 45 and 65 degrees centigrade. Place the tube of the spray product in a bucket with 1 litre of warm water and empty it. The filter needs to be cleaned at the same time. For that purpose, the cap should be removed so that the filter inside can be cleaned with warm water as well. If there is too much residue of old spray product, then the filter can be cleaned in an alkaline solution (0,5 litre of Astri-Lin in a bucket with 10 litres of water). Leave the filter in the bucket for 1 to 2 hours, wash it carefully with pure warm water, and place the filter back in the holder. The nozzle should be cleaned as well, using just warm water. When taking the nozzle apart, please be aware of the fact that it may contain some loose but essential parts!
