Development
Overview
- Milking Unit are the components that attach to the dairy cow and produce pulses for alternating vacuum/atmospheric air entry cycles
- Vacuum System is the components that produce and regulate the vacuum level
- Collection System is the components that accumulate milk and pump it to a bulk tank
- See page 8 of link "Milk and Milking" for a full diagram
Milking Unit
- Includes the pulsator, teatcups, short and long milk tubes, short and long pulse tubes, and the claw.
- Claw
- 1 port for the long milk tube
- 4 ports for the short milk tubes
- 1 port for the long pulsation tube
- 4 ports for the short pulse tubes
- Teatcup
- Metal or hard plastic teat cup shell attached to a flexible rubber or synthetic teat cup liner
- Space between the teat cup shell and teat cup liner is called the pulsation chamber
- 1 port for the short milk tube
- 1 port for the short pulsation tube
- Pulsator
- Small machine that alternates between applying vacuum at the teatcups and admitting air at atmospheric pressure to the teatcups
- 1 port for stall cock
- 1 port for long pulse tube
Vacuum System
- Vacuum Gauge
- Placed inline with the pulsation lines and also between the vacuum reserve tank and vacuum regulator
- Measures vacuum pressure
- 2 ports
- Vacuum Reserve Tank
- Distributes vacuum to the pulsation header lines and milk header line
- Buffers the vacuum level for when air enters the vacuum system
- 1 port for milk header line
- 2 ports for pulsation header lines
- 1 port for main vacuum supply line
- Vacuum Pump Filter
- Prevents particulates from entering the vacuum pump
- 1 port for intake to main vacuum supply line
- 1 port for outtake to line to vacuum pump
- Vacuum Pump
- Applies a partial vacuum in the system
- 1 external port
- 1 vacuum port
- Vacuum Regulator
- Prevents vacuum level from increasing excessively by allowing air into the vacuum system when the vacuum level reaches a preset value
- 1 external port
- 2 inline ports
- Vacuum Relief Valve
- Prevents vacuum level from increasing excessively by allowing air into the vacuum system when the vacuum level reaches a preset value in case the vacuum regulator fails
- 1 external port
- 2 inline ports
- Sanitary Trap
- Separates the air-only vacuum system from the milk collection system
- Prevents liquid and particulates from the milk collection system entering the vacuum system
- 1 port to vacuum system
- 1 port to collection system
Collection System
- Milk Receiver Jar
- Collects milk from the milking units
- 1 port to vacuum system
- 2 ports to milk pipelines
- 1 port to milk pump
- Milk Pump
- Pumps milk from the milk receiver jar to the bulk tank
- 1 port to milk receiver jar
- 1 port to milk filter
- Milk Filter
- Prevents particulates from entering bulk tank
- 1 port to milk pump
- 1 port to bulk tank
- Bulk Tank
- Main collection container for milk
- 1 port to milk filter
- 1 port to sink for yielding milk
