Milking machine is to improve milk quality and work efficiency, reduce labor intensity of one of the key technical measures. When milking machine to imitate calf suck the milk of physiological action, negative pressure generated by the vacuum pump, vacuum milking regulator control system of vacuum degree, pulsator produce milk and break beats, air set with holes into the collection of milk, from the collection of milk to make milk to milk duct.
1 the specific operating procedures
1, preparing work before computer (1) clean the milking machine. With 40 ℃ hot water washing before milking milking machine for 5 minutes, rinse clean the pipe, at the same time check whether system normal operation. (2) the cow baoding. Use milking machine milking before a period of time (usually for a month), milking cows don't adapt to the milking machine, in the process of milking will panic, affect the milking operation, before milking cows baoding should be good. Baoding methods: make a slipknot with rope trapping double Angle, and then around the cow's head front set a slipknot, chained his cattle on the railing, fixed well. (3) the nipple medicated bath and dry. After the cows are fixed, and before the milking use disinfectant first four nipples bath for 3 minutes, then wipe dry. If he is not dry, milk cup in front of the inner tube closed air chamber pressure increases, the equivalent of milk cup, oppression nipple roots, cause milk to be difficult, nipple is congestion at the same time, cause nipple valgus, cause mastitis. (4) the crowd out first three milk. It can stimulate milk, make the nipples slightly open, at the same time can also check the health of the breasts. If you have mastitis, do not put on milk cup, available artificial milk alone. The extrusion of the first three milk must use special containers, in order to reduce pollution to the environment. (5) breast massage. In the first three to crowd out milk and cleaning after breast, nipples and breast not full, tight, that have not yet fully formed reflex, it must continue to massage the breast, until the row of reflex fully formed. In nipple and breast skin has a lot of pressure and tactile sensor, the massage form of transmission to the brain, nerve excitement oxytocin secreted by the pituitary gland, with blood circulation effect to the mammary gland bubble around inside the breast muscle cells, shrink the extrusion of mammary gland bubble, to pass through the lactiferous ducts into the breast milk pool.
After 1, 2, computer problems
On 1, 2, 1 set of milk a cup of milk After the row of breast reflection form, as soon as possible on the milk cup milk, otherwise the milk from the mammary gland bubble pool milk will ease or interrupt. The role of oxytocin time usually lasts for 7 ~ 8 minutes, if you don't timely set of milk cup, will shorten the milking the role of oxytocin, residues of breast milk is much. So the general requirements from the crowded three milk within 1 minute after the milk cup, because the blood concentrations of oxytocin has risen to the top. Set the order of the milk cup is: milk area on the other side of the left hand began to set in turn clockwise cup, so convenient and safe. Each milk cup must be set in the form of sliding, and should try to reduce the Angle of air into the milk cup. Milking machine pressure should be set at 49, 1 ~ 50, 8 kPa, pulsation frequency per minute
Bell is 60 ~ 70 times, not too high or too low.
1, 2, 2 check milk flow check every milk area velocity, if there is a milk area when not in milk, should stimulate the secretion of milk cup, to stimulate the milk area to milk on again, and began to do the milking.
1, 3 problems that should be paid attention to after milking
1, 3, 1 right off the milk cup After milking, should first turn off the vacuum valve, then remove milk cup, avoid to use milking machine to squeeze dry milk, thereby increasing stress of the breast tissue and air into the milk cup, increasing the likelihood of mastitis happened.
1, 3, 2 nipples medicated bath After milking, use disinfectant soaking nipple disinfected immediately. Disinfection should be completed as soon as possible, because inside a few seconds after milking, the pipe nipple is open, after medicated bath disinfectants will enter an open pipe nipple, still can make the disinfection is attached on the nipple, forming a layer of protective film, can significantly reduce the occurrence of mastitis. Nipple medicated bath can use 3% sodium hypochlorite or new jie er die or 0 0, 3%, 2% acetic acid peroxide.
1, 3, 3 recycling of milk After milking, the each set on breast milk first level calibration record is good, in order to calculate the day when the time of milk production. Then set back the milk in the milk is milk barrels or special milk containers. Be careful operation, because the milk from the milk pipe of the impact is very big, if the milk bucket, the unstable hand easily. At the same time, the milk pipe from a barrel to be very careful when transferred to another bucket, so as not to spill milk on the floor to cause unnecessary waste and pollution.
1, 3, 4 clean milking machine Milk after the recycling, milking machine clean thoroughly, so as to avoid residual milk pollution next time out of milk. The milking machine cleaning must be used special detergent (such as PC, PC - B detergent). PC - can use rotation and PC - B, first wash pipe with PC - B after three times, then clean with PC - A 1 time, in turn used interchangeably, the final rinse. Cleaning procedure: first with 40 ~ 50 ℃ water washing to remove residual milk, and then clean with 70 ~ 75 ℃ detergent solution cycle, with 90 ℃ water, finally ruled out until the pipe water to neutral.
Note 2
2, 1 milkman training qualified rear can mount guard At ordinary times should pay attention to health, work clothes often should change and regular disinfection, long fingernails short and smooth, to at any time in the process of operation with sterilized wet wipe clean hands. To be equipped with familiar with milking machine of professional management, maintenance, maintain the milking machine.
2 · 2 milking vacuum requirement vacuum rate is too high, easily damaged papillary muscle valgus, its mouth there hard; Vacuum rate is too low, will reduce the milking speed, milk cup is easy to fall off. So, high pipeline milking machine vacuum pressure should be kept in 49, 1 ~ 50, 8 kPa.
2, 3 pulsator pulsation frequency requirement is too high will damage the papilla sphincter, bacteria easy invasion of nipple; Frequency is too low, easy to make hyperaemia of nipple, induce mastitis. Normal pulse frequency 60 to 70 beats per minute. Should be tested once a week pulse frequency, keep pulse frequency stability.
2, 4 pay attention to safety Meet not docile cow, be careful on the milk cup, so as not to hurt or be kicked cattle bad milk cup. Can use rope the cow two hind trapping; Also can use left hand try to gently touch the breast, after waiting for cattle distraction, quickly put the milk cup set. It is best to use the second approach, after a period of time, the cow will naturally be tamed. In the process of operation, be careful driving and treat cow, cannot use beating and kicked.
2 · 5 against the stimulus set of milk cup, the first with the hand rub your breasts, after waiting for cattle have prepared combined with milk cup, avoid by all means is suddenly on the milk cup. Especially cold winter, if suddenly put on milk cup, cold milk cup can produce stimulation to breast, female breast steak. Milk cup liner is milking machine only part of the direct contact with the nipples. Milk line health directly effect on the quality of health and the milk of cows, so often should carry on the disinfection, it is best to 1 times a day.
2, 6 note in the process of health milk if milk cup drop on the ground, take the dirt on the milk cup thoroughly cleaned and then on to avoid pollution of nipple and milk.
