Latest milking machines are designed automatic


Milking machines functions enlightened in Dinamalar show

“Latest milking machines are designed automatic and take-off device removes the machine from the cow when milking is completed” said a market person of Milking machine in Show of Livestock and Agricultural Equipment organized by Dinamalar in Karur. The  exhibits include production, procession and packaging of fresh fruit and vegetables, cereals and legumes, green housing, agricultural machinery, equipment, accessories, food processing and packaging machinery, cooling, storage and handling machinery, seed, fertilizer and plant protection pesticides, irrigation machinery and equipments, organic agriculture, solar energy, organic farming, cattle feed and several other areas of interest to integrated farming.Hugues, a French volunteer of OFI-SEVAI Cow project said that it was a premier event for products in livestock production and Agricultural Accessories and the visit was a unique opportunity for him to know the emerging technology transfer to farmers. One of the organizers of the Dinamalar show of Live stock and agriculture equipments helped Huges to show him around the show stalls. The market person of Milking machines said further, “Milking machine design and function is critical for rapid and efficient removal of milk without damage to the teat or gland and with minimal risk for transmitting pathogenic microorganisms that might cause mastitis. The only way for mastitis-causing organisms to enter the teat is through the streak canal. This is the same route by which milk leaves the gland, therefore, anytime that the streak canal is opened to remove milk the gland is susceptible to potential intramammary infection. Much of the recommended process of milking relates directly or indirectly to control and prevention of mastitis. The physical and functional interface between the teat and the machine are carefully designed to minimize the chances of intramammary infection occurring as a result of milking. The machine includes teat cups that contact the cow’s teats and remove the milk, a claw where milk pools as it is removed from the four teats, vacuum tubes that provide vacuum to the teat cups and a milk tube that removes milk away from the claw, a source of vacuum for the machine, and a pulsator that regulates the on-off cycle of the vacuum. Many milking machines today have an automatic take-off device that removes the machine from the cow when milking is completed. Most cows have four functional teats. . These are composed of an inner rubber liner and an outer shell, usually made of metal. The rubber liner is relatively thin in the section that sits inside of the shell, while the liner’s tube below the shell is thicker rubber. When the teat cup is applied to the teat, the end of the inside chamber is filled by the teat. During the milk phase the vacuum applied inside the liner is constant and keeps a constant negative pressure at the end of the teat, drawing milk from the gland. The vacuum applied to chamber B, between the shell and the thinner walled part of the liner, keeps the liner from collapsing under the vacuum. During the rest phase, the vacuum inside chamber B is monetarily off. The lower part of chamber A maintains its vacuum, while the upper part around the teat momentarily loses vacuum. This alternating vacuum-atmospheric pressure in chamber B is controlled by a pulsator, alternating vacuum-atmospheric pressure, referred to as pulsation, is important for maintaining teat end health”.Govin
