By Steve Shore – Once I first needed a goat milking machine I seemed in all of the goat farming provide catalogs and behind the American Dairy Goat Affiliation’s listing for the proper goat milking machine. I purchased one from one of many goat milking provide homes that was “designed only for goats.” I ordered a two-goat milking machine and was shipped a one-goat milking machine. The provider talked me into preserving the one-goat milking machine. It was usable however the small milk bucket wasn’t fairly sufficiently big when used on my best doe. The froth from the milk can be sucked into the small vacuum tank and the milk bucket was so mild that it tipped over simply. Then after utilizing if for much less {that a} month, the electrical pulsator stop. I packed it up and despatched it again.

Later I purchased a unit from Mick Lawyer. It makes use of a Gast pump which you could get from W.W. Grainger for about $325, a compressor tank, vacuum gauge, and vacuum reduction valve. It’s so simple and easy I want I had considered it. The milk bucket is a surge with two-foot-long hoses on the inflations, so the bucket will set on the ground and the inflations will attain the goats on the milk stand. Sure, you may milk two goats at a time.

This unit works very effectively, however whereas at a goat present I began speaking to an previous cow dairyman whose spouse has goats. He confirmed me his “present machine.” Let me let you know this factor was a magnificence. He had an air-con pump off a automobile hooked as much as a 1/3 hp motor, and his tank was a 12-inch pipe that was capped with a bit of plate. He didn’t trouble to trim the perimeters of the plate off or something. His welds have been ugly and it was leaking vacuum. However the very best was the vacuum relief-a piece of plate over a gap within the backside of the tank with weights hanging on a series. The one factor that seemed respectable on this factor was a model new vacuum gauge.

He defined that the air-con pump from a automobile is definitely a vacuum pump. To show the pump you want a 1/3 hp reversible motor that turns at 1,725 rpm. It must be a reversible motor as a result of a automobile engine runs backward from a regular electrical motor. You must tack weld the clutch pulley on the vacuum pump so it received’t simply spin. Your vacuum tank will be something that received’t collapse beneath 11 kilos of vacuum. His pump might even sustain with the vacuum leaks from his poor welds. When requested about his vacuum reduction set-up he instructed me that to manage the vacuum, you add or take off weight whereas watching the vacuum gauge. When the vacuum will get greater than the load of the weights hanging on the chain, the plate within the backside of the tank lifts up inflicting a leak, and the vacuum is decreased. It’s so easy it’s ridiculous. Once I got here again residence I simply needed to make my very own goat milking machine. I had a bit of 4×18 tube laying round from a job I had been on. I capped each ends and floor down the welds, and added some angles on the highest to mount the reversible motor on (I had to purchase that), picked up a vacuum pump off a good friend’s junker, and a few pipe fittings. I purchased a brand new vacuum gauge and vacuum reduction valve from W.W. Grainger. Now I’ve one other good working goat milking machine.

Some notes on constructing your individual goat milking machine: attempt to get a pump off an enormous automobile or a nine-passenger van-it can be larger than a small economic system automobile’s pump. You must weld the pulley to the electrical clutch on the pump, or the pulley will simply spin. Your motor should be reversed and 1,725 rpm and not less than 1/3 hp. Use a very good dimension tank, too, if it’s small you lose vacuum too simply. Purchase a brand new vacuum gauge and watch it. The dairy provide homes promote a vacuum reduction valve for over $40; Grainger’s sells one for about $10. Each work on the identical principle-a spring that holds pressure on the valve to regulate vacuum. I’ve each varieties and have by no means had hassle with both. Whereas the load on the chain works (the previous surge pumps did use them) it takes up a variety of space-spend the $10. For a milk bucket, you will discover them on eBay. I might stick to the Surge belly-style, as you may simply get substitute components.

There was a query about changing a compressor right into a vacuum pump. Whereas in concept, it ought to work, it doesn’t work very effectively in any respect. Your consumption stroke doesn’t have sufficient vacuum in it to do a lot good. You’ll be able to truly run your milk bucket off your automobile’s consumption manifold however as soon as once more you want a vacuum gauge and a method to management your vacuum. By the point you pay for the fuel in your automobile, the hose to go to your milk bucket, the gauge and reduction valve, you would possibly as effectively purchase an electrical motor.

I exploit the one-piece silicone inflations by Sil-Tec or Marathone. I just like the Sil-Tec’s higher as a result of they’re cheaper. Each manufacturers are clear on the backside the place they connect to the milk hose. I connect the inflations immediately on to the hose with none elbows or shut off valves to shut off the inflations. I exploit the plug-in sort inflation plugs, this retains something from getting contained in the inflations. I exploit a DeLaval bucket with a surge lid. The DeLaval bucket sits increased so my milk strains are flat out to my stanchions, making them shorter. By utilizing the Surge lid and pulsator, I don’t want a claw, and the Surge pulsator is simple to rebuild and you should purchase the components from most dairy provide homes. Put a drain in you vacuum tank. Your vacuum tank will choose up moisture from condensation and milk vapors. When individuals inform me that their goat milking machine isn’t working proper the very first thing I inform them to do is to empty the tank. This often solves their drawback. You see when the tank begins filling up with milk or water, you cut back the quantity of vacuum within the tank and you might be working simply off your pump for those who get a leak in vacuum (akin to when a goat kicks off an inflation or you might be switching inflations from goat to goat) you lose vacuum. For those who don’t have sufficient reserve vacuum in your tank, inflations begin falling off or the pulsator stops.

You may make a water entice with an auto drain. Mine is made out of three-inch PVC about 12 inches lengthy, capped on one finish with a threaded cap on the opposite end-this manner it may be taken aside for cleansing. On the capped finish drill and faucet a gap for a 1/2-inch pipe and screw a pipe becoming with a hose barb into the outlet. Seal it with Teflon&153; tape so it received’t leak. On the opposite finish drill and faucet a gap in the course of the threaded cap and one within the aspect of the pipe, down low. Screw one other threaded hose barb becoming into the outlet within the aspect of the pipe. You’ll need to solder a brief piece of copper pipe right into a male copper adapter to your duckbill to suit onto, then screw it into the outlet within the threaded cap. You’ll be able to hose clamp the entire thing onto your goat milking machine or your milk stand. Run a hose out of your vacuum pump to the highest hose barb, and the hose to your bucket to the underside hose barb. For those who suck milk or water into your vacuum strains it would gather within the backside of your entice and never your tank. While you flip off your pump the water will run out of the duckbill.

In case you are milking multiple or two goats you might be spending a variety of time shifting goats from pens to take advantage of stand and again once more, and ready for them to complete consuming. The answer is to make a stanchion that holds extra goats. (I used to be an ironworker, and lots of occasions I drove 100 miles a technique simply to get to the job. In the summertime we might begin work at daybreak to beat the warmth, so I had no time to waste ready for the goats.) I constructed an eight-goat stanchion and milked two goats at a time. From the time I walked out of the home to the time I walked again in took 35 minutes. This included clean-up of eight goats within the stanchion at one time: wash the primary two udders, begin milking from the proper to the left, wash the opposite six udders whereas ready for the primary two to take advantage of out. I teat dip as I am going. After the final two are milked out, lower all eight unfastened directly and run them again to the pen, and dump the milk into ready jars. I had a two-section sink with cleaning soap in a single aspect and bleach within the different. I’d flip the pump on and suck 5 gallons of soapy water up, dump it and do the identical with the rinse, then head for the home. I did a extra thorough cleansing once I obtained residence after work and I had the feed within the feed bowls at evening and the goat milking machine all arrange.

One last item. In case you are these actually cute stomach milkers to your goat, please don’t waste your time or cash. The Surge stomach milkers hung beneath the cow. The cow might transfer round and the bucket would transfer with it. With the goat arrange, the bucket is light-weight and units on the milk stand. In case your goat is tall, the inflations will pull down on the udder; if the goat is brief or has a big udder, the bucket and inflations can be pressed towards the udder. If the goat strikes the bucket is moved with the goat, typically scaring the goat sufficient to make it beginning leaping round. Everybody I’ve talked to that has a goat stomach milker hasn’t favored it. Don’t waste your cash.

For those who’re elevating goats for milk, I hope this offers you sound recommendation on goat milking machines.
