The principle of operation of an
juicer To make a juicer for apples, grapes or other berries and fruits, you need to understand how it works. In its design should include such parts:
- chopper, which will destroy the shell of the fruit;
- press, squeezing juice;An
- filter or something like a sieve or colander to filter the juice;
- capacity in which the juice is poured.
A grater can act as a chopper if the home-made juicer is intended for apples or other hard-shelled fruit. You can also use a mixer, mounted on a drill, which makes a large number of revolutions.
A method of making a grater and filter from an
washing machine. Now let's take a closer look at how to make a juicer with your own hands so that it can quickly squeeze juice from apples. To do this, you can use parts of the old washing machine with traditional horizontal loading laundry. The machine is dismantled, remove the drum and its casing, as well as the mounting bracket with bearings. Bearings must be in good condition, replaced if necessary.
The drum is like a sieve through which the juice from apples will flow. In the casing should remain one hole through which the juice will be collected in a jar, pot or bucket. The remaining holes are covered with rubber pads, pressing them with bolt-on plates. Plates should be made of stainless metal.
Because the juice from apples and other fruits contains acids, the home-made juicer must be equipped with parts made of stainless materials that do not emit hazardous substances.In order to make a grater, a circle is cut out from steel with a thickness of 2 mm and a diameter of 22 cm and a second circle from thin steel with a thickness of 0.5 mm of the same diameter. Thin steel will play the role of a gasket to increase the rigidity of the grater. The gasket should be attached to the bottom of the drum-sieve on three racks of brass. Previously in it, as well as in the grater, they make five holes for fastening on the grater screws.
Now you need to fill the teeth, which will cut the fruit. For this, a 2 mm steel circle is fixed on plywood with a minimum thickness of 10 mm. Then the circle is divided into identical sectors( usually up to 20 sectors), and the notches are filled with a punch. The marking must be done very precisely so that during the operation of the grater it does not move and is located strictly in the center of the juicer.
To juice flowed clean, it is necessary to reduce the holes. For this purpose, a mesh with cells with a diameter of about 1 mm is packed inside the drum. The smaller the openings, the more homemade juice extractor will produce a more transparent juice.
How to make a hopper for loading and pusher
A bunker is required to load apples or pears. It is made from a piece of plastic pipe and fixed so that the fruit spilled on the edge of the grater. The diameter of the pipe must be such that an apple of medium size calmly slips into it. A diameter of 10 cm will be suitable for an engineer. You can attach the hopper to the washing machine casing using four aluminum corners and bolts that are inserted from the inside.
The size of the crushed apple particles will depend on the size of the gap between the grater and the lower part of the bunker.To make a pusher for apples, use a handle for hand-held agricultural tools. It should be made of non-resinous wood. Ideal birch. To prevent the pusher from falling inside the juicer, a limiter is placed on top of it. At the bottom, attach a plywood circle slightly smaller than the diameter of the pipe.
Collecting Juicers
When the individual parts are ready, they are assembled together. The engine, which will rotate the drum, is selected separately. A commonly used 1.1 kW DC motor. This is enough for high performance. You can take less power, more is undesirable, since there will be strong vibrations, and a homemade juicer will fall apart.
The tank cap can be cut from thick polyethylene. The frame for fastening the casing is welded from the corners. Fasteners must be securely clamped, and electrical contacts must be insulated, protected from splashes and moisture.
The finished structure should be washed with dishwashing detergent and rinsed with plenty of water. Then do a test run, checking how the drum is spinning. After each use, rinse the drum with water.
Other methods of making juicers
If you can not figure out how to make a juicer from a washing machine or you do not have suitable spare parts, then you can go the other way.
To grind apples, use a mixer for mixing mortars, cutting a few bolts into the bottom. The mixer can be put on the drill by increasing the number of turns. Apples are crushed in a bucket, after which the resulting mass is placed in a bag, placed in a press and squeezed. A bag is needed in order to separate the cake.
Here the difficulty lies in the manufacture of a press that will squeeze out the juice as accurately as possible. The capacity into which the chopped apples are loaded is made from a large pan, having drilled holes in it. Some specialists use a mechanism that presses bearings as a press. You can make a press yourself, having installed a jack from above.
Fruit Preparation
The collection and preparation of fruit processing takes the most time. They need to wash, sort, let the water drain. Large fruits can be cut into pieces, the bones do not need to get. Rotten apples and pears throw out, because they negatively affect the taste of the finished juice. Cake is used for fermentation or give for animal feed.
If you have a juice with a small amount of pulp, cake, then let it settle. After this, drain, boil and pour into banks. You can pasteurize the finished product, excluding boiling. In this case, you save the maximum amount of nutrients.
