How Milking machines work?

Discover how to get milk from a cow

The milk is extracted using a vacuum applied to the cow’s teats. Milk stored in the udder is drawn into a system of pipes leading to a receiver tank where the milk is collected before being passed to the cooling tank. A ‘cluster’ of four teat cups – each consisting of a stainless steel shell, a ﬂ exible rubber lining and a short pulse pipe – are attached to the teats. Between the outer shell and lining is a pulsation chamber that collapses with the addition of air from a pulsator. When the chamber is devoid of air (milk phase) a vacuum is created, which gently draws milk from the teat. When the chamber is ﬁ lled with air (rest phase) the lining of the teat cup collapses and massages the teat. Continued repetition of these phases not only aids milk production by mimicking the action of a suckling calf, it also promotes blood circulation. To help the milk ﬂ ow away through the pipeline, once out of the cow the milk is mixed with air added by a claw, the claw connects the teat cups to the milk and pulse tubes.

1. Teat cups

Each cluster consists of four teat cups themselves each made up of a metal shell, a rubber lining and a short milk pipe.

2. Pulsator

The pulsator is the valve on a pipe that’s connected to the claw and adjusts the air pressure in the pulsation chamber. The pulsator is attached to a main air pipeline that feeds into the claw.

3. Milk phase

When air is drawn out of the pulsation chamber inside the teat cup, a vacuum (suction) is created around the teat. The pressure difference opens the teat canal and draws the milk out.

4. Rest phase

When air is pumped into the pulsation chamber inside the teat cup, the lining collapses, massaging the teat and closing the teat canal.

5. Long milk pipe

A short milk hose connected to the teat cup directs milk away from the cow to the claw where it’s transported – together with the milk from other cows – to the main milking pipeline.

6. Claw

Beneath the teat cups is the claw, which connects the short pulse pipe and milk pipes to the main system’s long air pipes and long milk pipes. Here air is added to the milk to help it ﬂ ow through the system.

7. Milk pump

A motor-driven milk pump removes the collected milk from the main pipeline and transports it to the receiver tank for chilling and processing.

HOW CAN WE MOTIVATE OURSELVES MORE EFFECTIVELY THROUGH REINFORCEMENT?

•We'd all like to be more effective in reaching our goals, and according to behaviorists, the way to improve our effectiveness is by rewarding ourselves for the little steps that take us closer and closer to those desirable outcomes. •First, find something you really like to do or something you'd like to have that can, realistically, serve as a reward. •Then, take the goal that you are hoping to achieve that, realistically, you could achieve but just haven't succeeded at yet. •Next, work backward from that goal to your present state. •Arrange to give yourself those desired rewards as you inch closer from where you are now to the desired end point. •As you start to make progress, only give yourself a reward when you've moved forward from where you are now. •For example, if you'd like to cut back on your television watching and instead read more often, reward yourself by allowing yourself to watch television only when you've read for 20 minutes,

15 Did You Know Fact that will surprise you

1) Did you know that this colourful little chap is the Costa Rican Variable Harlequin toad aka the Clown frog. 2) Did you know that the Karni Mata Hindu Temple in Rajasthan, India, is also known as the Temple of Rats. The temple is famous for the approximately 25,000 revered black rats that live there. Visitors play with and feed the rats and even sometimes drink from the same milk and eat the same food. 3) Did you know that vanilla flavoring is sometimes made with the urine of beavers. 4) Did you know that Botox is made from botulinium toxin which is considered the most deadly substance in the World as half a pound would be enough to wipe out the entire World population. Almost all the Botox in use throughout the World is made in one single factory in Ireland. 5) Did you know that tuna swim at a continuous steady rate of about 14km per hour for their whole life until they die. Whilst alive they never stop moving as if they stop they are unab

WHY DO WE SLEEP AND DREAM?

•We spend about one-third of our lives sleeping. •Why do we invest so much time in sleep? •The most straight forward answer is that, sleep is restorative, and it replenishes the body's energy stores. •However, intense neural activity during rapid eye movement (REM) sleep, the stage in which most dreams occur, suggests there may be more to the story. •One theory, which by far has the largest body of evidence, is that sleep plays a critical role in learning and consolidating memories. •It is probably why infants and toddlers need up to 14 hours of sleep a day, with half of it spent in REM sleep. •In adults, dreams may also play a role in brain plasticity and learning, which is why sleep-deprived adults perform worse in memory tests and tasks.
