Pneumatic Milking Pulsator 60/40
What does the Milking pulsator do?
The pulsator operates the liner: Pretends like calf sucking. Calf sucking behavior!
When the vacuum curve is down there is no vacuum outside the liner, but there is vacuum under the teat.
The liner will close and “massage” the teat, preventing congestion. When the vacuum is high the liner will open, not pressing on the teat, and milk will start flowing. Closing the liner when the teats are empty, and with strong force (high vacuum under the teat), is painful for the cow – and will damage the teat end.
How the pulsation cycle works
There are two parts to a pulsation cycle:
- Milking or Open Phase – when the pulsation chamber is under vacuum, the liner moves to its open position, as above. Milk is drawn out of the teat, as it moves from a place of high pressure (i.e. in the udder) to a place with a low pressure (i.e. vacuum in the milk tube).
- Resting or Closed Phase – Air is admitted into the pulsation chamber, which increases the pressure to the same as the atmosphere, exceeding the pressure (vacuum) on the other side of the liner wall, causing it to collapse around the teat. Milk flow slows and stops.
Models of Milking Pulsators
Milk Pulsators is the essential part of Milking Systems & Milking Machine, which is divided into 2 types, Pneumatic Milk Pulsators and Electric Milk Pulsators. And Models are: 4 nozzles to milk up to 2 cows at a time and 2 nozzles are for one cow milking at a time.
The best available today in terms of simplicity, precision, sturdiness and reliability. It has been designed with great attention to detail for a complete animal milk out, to promote good udder health and to make life easier for the farmer.
How pulsation affects milking efficiency
Many dairies have been set up with a ratio of 60:40 and rate of 60 ppm. In some situations, milking efficiency can be improved by increasing the period that the liner is open in each pulsation cycle. This is achieved by extending the ratio to 65:35 or 70:30. When making this change it is important to do a machine check to ensure a d-phase of at least 150 milliseconds, and 20% of the cycle, is still being achieved.
When the pulsation ratio is increased, the teat will be exposed to vacuum for longer in each pulsation cycle. It is important to minimize the time that the teats are exposed to vacuum once milk flow slows down or stops. This can be achieved by applying maximum milking times (MaxT) or setting Automatic Cup Removers (ACR’s) low flow threshold to achieve earlier cup removal.
Typically, increasing the pulsation ratio to 70:30 is only recommended in these types of situations:
Milking goats
the ideal conditions for milking goats with air inlet teat cups in the milking machine are a vacuum level of 36–38 kPa (low line) and 38–40 kPa (high line), a pulsation rate of 90 cycles/min and a pulsation ratio of 60:40, while the ideal conditions in the sheep milking machines are a vacuum level of 35–36 kPa (low line) and 36–38 kPa (high line), a pulsation rate of 120 cycles/min and a pulsation ratio of 60:40 or 50:50.
