The portal authors don’t like rotary juice squeezers that produce a bucket of juice for 5 minutes, why twin-screw models don’t always want to put it at home, what to do if you want banana puree, why it’s not appropriate to use presses in wine making in Spainreaders of the review will find answers in the article. Consider a press type juicer.
From the history - the background of the invention of the pressing juicers
Press juicers are of three types. But there are only two methods for obtaining a drink. Main whales:
- Hand press.
- Juicer with a vertical auger.
- Horizontal Auger Auger.
The last two are similar in organization. People do not like rotary( centrifugal) models, and the reason is clear: the high speeds of the moving parts of the device heat up the juice, which loses its useful properties.
According to the ancient Italian tradition, grapes crushed with their own legs beauties of a very young age. They lift up their skirts just above the knee, climb into the barrel of two or three people and begin to knead the grapes intently with their feet. True lovers do not hide the fact that the sweat of the working women gets into the wine, but this is in the order of the norm and perfectly complements the bouquet. Therefore, the inventor of the manual pressing juice extractor from a decent vineyard would be driven into the neck. It is difficult to say whether the best wines of Europe are produced in the traditional way, but we will easily explain what the manual press for juice extraction represents.
Manual press-type juicers
Imagine a hefty faucet valve of the pipeline, rotating the cast-iron round handle of which along the axis, the workers block the flow of water, then resume it. The manual press juice extractor works in a similar way. Includes parts:
- Robust massive bottom.
- An arched frame with a vertical threaded hole in the middle.
- Cylindrical walls with regular and dense holes cut through.
- Threaded axle with handle on one end and piston on the other.
- Circular chute, covering the walls around the perimeter, with a drain spout.
Consider the order of work. Up to the stop, the piston shaft turns upwards. The container is filled with raw materials: vegetables, fruits, grapes. .. Now a couple of hard workers take the handle, one on each side, begin to walk in a circle, screwing the piston straight down into the pulp. Manual press juicer is extremely massive, you should not think that the actions described are a joke or exaggeration.
As the pulp squeezes, fruits, vegetables, and grapes begin to give out juice that flows through the holes in the wall and collects in a circular groove located at the bottom. It is easy to guess that soon the product starts to pour out of the spout. In the specified place it is recommended to substitute a collection container.
Looks easy. In fact, there is no simplicity in the press juicer of this type for the above reasons:
- Firstly, not every product is soft, the design must remain extremely durable. This applies to the bottom of the juicer, the walls - a special conversation about them - and most importantly: arches, axles and pistons.
- Two workers, twisting the handle, create monstrous force, any misalignment will easily break even strong steel. The piston must move clearly inside the cylindrical walls, if one of the holes is accidentally pinched with an edge, a large manual accordion-type press juicer will result. Metal simply somnet.
- Special requirements are imposed on the wear resistance of rubbing surfaces. Mainly refers to the walls. Pieces of metal can easily get into the final product, after the publicity of the newspapers, the company faces a loss of prestige brand juice or wine.
The press extractor juice extractor described is intended for semi-industrial use. Obvious difficulties immediately appear before the eyes of an experienced observer. In the manual juicer is extremely difficult to ensure the hygienic output product. Wine, crushed by beauties, will begin to reach in special conditions, and the sweat of workers in children's juice looks out of place. Thinking over a moment is relied upon by a businessman who has undertaken to make juice using the power of living people.
Press-type Juicer withvertical screw
Power catches the eye. The Mulenexx juicer with a vertical screw copes with duties at a nominal consumption of 150 watts. For information, the first-generation Pentium microprocessors ate 75 watts, no less. These devices - press juicers with a vertical screw, and not processors - are extremely economical. Will have to pay the owner. Specially provided reverse, because the carrot is able to put the device in an awkward position. You have to twist the screw alternately in both directions.
Getting Started! Imagine a cylindrical perforated, as in the previous description of a manual juicer, but instead of a piston, a vertical auger rotates inside, pushing the flesh down. The screw - an axis with a pronounced, huge thread, like a meat grinder. The core is clearly thickened to the middle, made of plastic. If the motor is represented by the heart, the thing will be the hands of the juicerThe operator through the narrow( in selected models and wide) neck pushes inside the vegetables, fruits and grapes. Then the auger takes over: carries the product, crushes and presses against the bottom and the perforated wall.
The separation of the cake and juice helps rotating the outside frame in a circle. It scrapes off the pulp that has crawled into the holes and at the same time collects the pressed through the bottom. The principle of operation is difficult to understand, but it looks amazing. Every second( with a similar speed the frame rotates) a wave from the juice arises inside the screw-type press juice extractor. The useful product is re-filtered and discharged through the nozzle. Everything else is pushed lower and out through the nozzle two in the form of semi-dry meal.
A curious experiment by representatives of the company Sigmundstein proved the superiority of the model over the usual rotary juicers in a demonstration video test available on YouTube. And the efficiency of the juicer at a height, and the device is safe, and the screw rotates slowly, which means it does not deprive the drink of useful substances.
Video Test shows that the juicer handles vegetables, fruits and berries that contain a large percentage of water. In general, the Siegmundstein unit is a good tomato juicer.
Comes with two grids:
- for juice;
- for mashed potatoes.
Press the juicer with a horizontal screw
The press juicer with a horizontal screw resembles a meat grinder. On most of these units it is possible to get mince, even homemade sausage. Such a “meat grinder” turns the pulp into a porridge, which the mass pushing from behind presses against the grill. As a result, the juice through the nozzle is poured down, the pulp comes out in front of the pressing juice extractor, resembling a device for receiving minced meat.
Press Angel juicer is intended for raw foodists to enjoy any juices and vegetable puree. With a shiny stainless steel case, the device looks great. I have seen a screw-type press juicer of white plastic, where the carrot was pressed. The device turns orange, and forever. With the press juicer, the Angel of the incident will not happen, the steel does not absorb the natural dye of carrot or beet.
The screw is not at all a plastic harmless ball-shaped rod, like the models of the vertical type. Here we deal with durable tool steel, ready to break anything into pieces. Experts say that the press juicers horizontal type more economical rotary( centrifugal).This is logical, if you remember the order of prices. Much better expensive two-screw juicers!
Double-screw press juicers
Specially saved up the story about the devices at last, the evolutionary twin-screw pressing juicers came last, taking into account the experience of other structures. With the help of such equipment it will be possible to get the juice and squeeze out the oil from the seeds.
The process is based on an algorithm that is fundamentally different than that discussed above. Other pressing juicers try to crush the flesh against the walls and bottom of the vessels, the twin-screw models rub the source between two steel screws. Able to grind stone. Moreover, the glasses for collecting juice are supplied with magnets on the bottoms specifically to collect breakaway pieces of tool steel. With augers, this happens infrequently, but for the safety of consumers, the manufacturer has foreseen the possibility of the appearance of metal chips.
Today the described type of devices is popular in phytobars and takes precedence in preserving the beneficial properties of juices and purees.
