Convenience of use
The KitchenAid juice extractor tickles our curiosity. This is the first accessory for a food processor that we have tested in due form in our laboratory. At first glance, the 5KSM1JA is inevitably more compact than its competitors. Indeed, the base of the classic extractor disappears to leave only the upper part, that is to say the bowl and the chute. Proof of this are its condensed dimensions: 17.8 cm wide, 29.5 cm high and 24.6 cm deep.
To insist one last time on this point: no engine block is delivered with the device. Only a training module takes place in the box and is fixed on the front of the KitchenAid stand mixer. It is then the motor of the robot which operates the juice extractor. Remember once again that three models are compatible with the 5KSM1JA: the Artisan 4.8 L and the Mini 3.3 L that we tested, as well as the Classic 4.3 L.
If the extractor is compact, it does not forget the many parts necessary for the grinding of food. A juice bowl, chute and tray to help fruit slide down the auger make up the bulk of the device. Inside the bowl, a basket and a filter must be installed. The user has the choice between three different sieves to keep more or less pulp in the juice; one of them can even make coulis and purées. For comparison, the Philips Viva Collection HR1889/70 has only one. A box with lid is also provided by KitchenAid to store the two unused filters and avoid misplacing them. Finally, the last essential element, and not the least: the endless screw. Attached to it, a blade pre-cuts the food before moving on to the grinding stage. It is also the first device equipped in this way that we are testing.
Before operating the extractor, we assemble the parts and attach the cover; be careful to close it until it “clicks”. The device is well attached to the food processor, which we turn on at maximum speed (speed 10). Since it is the robot commands that operate the extractor, note that no “reverse” option is possible on this model; a useful option on certain references such as the Moulinex Ultra Juice ZU600110. Finally, we don’t forget to place the two containers under the 5KSM1JA. In this regard, KitchenAid has provided two bins of 1 l each; the juice one has a silicone lid to better preserve the drink after crushing.
We have washed and cut our food, now it’s juice time! Before starting, the user must push the pulp chute towards the device; if it is pulled outwards, the fibers will not be able to extract.
The manufacturer provides a tray, which is useful and facilitates the insertion of fruits and vegetables. The chute is not the widest in our comparison, but it allows food to be introduced without difficulty. Some, like the Ninja JC100EU, were problematic and we had to cut the carrots into pieces so they could be swallowed. To speed up the process, KitchenAid also supplies a pusher.
It is the apple test that opens the ball. About 200 g of fruit (211 g exactly) are about to be ground by the machine, skin and pips included. From the first quarter to the end of the crushing, it took only 37 s for the 5KSM1JA to swallow everything; a current record. At the end of the process, we recovered 147 g of juice, the equivalent of 69.7% of the initial total weight; which is a very decent performance.
It is the turn of the 192.5 g of carrots. The KitchenAid is still one of the fastest in our comparison. It is also one of the most efficient: 44.8% efficiency, against 26.6% for the Philips Viva Collection HR1889/70, for example. However, it is one of the only ones to see its engine struggle when grinding. When a large quantity of carrots reaches the auger, the robot slows down considerably. In his defense, this is one of the firmest foods he has to grind. In addition, we find a little more than 9 g of pulp in the juice; in comparison, the two worst devices in our comparison reached more than 12 g.
If the engine manages to keep up the pace on the oranges test, the problem lies in the amount of fiber left over from shredding. The blade retains the pulp, which smashes between the tray and the lid. The 5KSM1JA then obtains a yield of 58.8%, while the Riviera-et-Bar PEJ 730 reaches 65.3%.
We are now trying to insert herbs into the juicer, parsley in this case. From 50.1 g of parsley, we get 12.3 g of juice; which translates into a yield of 24.5% yield. Only the Philips Viva Collection HR1889/70 does less well (20.1%); the Moulinex Ultra Juice ZU600110 achieves 52.8% yield. No branch of parsley is found at the end of the grinding. The juice, on the other hand, is particularly thick; amazing texture compared to KitchenAid’s competitors.
Finally, we try to make our own almond milk. We therefore soak 35 g of almonds in 500 ml of water overnight. The next day, we pass everything to the extractor. Still just as fast (25 s), the 5KSM1JA obtains an efficiency of 90.8%. However, it leaves 26.3 g of residue in the juice, which is not the most pleasant in the mouth.
Maintenance is often the bane of juice extractors. With their many parts (7 for the KitchenAid), they become a real headache. As with the vast majority of its competitors, a brush is supplied with the 5KSM1JA to facilitate cleaning and dislodge residue from the corners of the device.
Once the grinding is finished, we disassemble the extractor and discover fibers stuck here and there in the tank and the sieve. Also, if the blade avoids jamming of fruits and vegetables by pre-cutting them, it inevitably involves more maintenance than on devices that do not have it. Pieces of food get stuck on this blade, without being able to continue their way to the endless screw.
The basket, which scrapes the sides of the bowl and ejects the drink towards the outlet, is not doing its job properly. It is then that a certain quantity of juice remains stored at the bottom of the bowl, without being able to flow into the collection tray. When disconnecting the tank from the drive module, it therefore happens that this juice flows onto the work surface.
Finally, a stop-drip system is also provided by the device. Paradox: it does not stop any drop. A plastic ball should normally clog the juice duct, but in fact, a small puddle of juice forms under the device after use.
