Watts

Most domestic blenders have between 200 and 800 Watts, however high performance blenders have much more. You can see and taste the difference – the high power is noticeable in the blending results. For instance, our powerhouse Optimum 9200A High Speed Vortex Blender boosts an incredible 2,611 Watt motor that can blend crunchy vegetables and hard fruit to a velvety consistency in around 30 seconds. It’s like the Ferrari of blenders!

RPM (rotations per minute)

The number of rotations per minute also influences the blender’s power. However, you need to know that this number is mostly a manufacturer specification and it usually can be reached only in laboratory conditions (think geek guys in white robes). These are what the engineers call “theoretical rotations per minute”, meaning the number of rotations per minute reached when the blender functions at idle speed. A much more decisive factor are the rotations per minute under load and the maximum time the blender can blend.

So how many rpm do you need to blend your favourite smoothie? Well, it depends of the ingredients. Fruit and vegetable smoothies are not a challenge and can usually be done relatively easy with most domestic blenders, even low priced ones. More challenging are the green smoothies you want to make using kale, spinach or mangold, when the target is to break the cellular walls of the plant cells. The highest nutrient value is concentrated in these cells, so these are exactly the compounds we want to break and blend.

Some engineers claim the cellular walls of the plant cells can be broken with a blender speed of 25,000 rpm. This could easily be achieved with all the appliances in the Optimum blender range: for instance, the above mentioned Optimum 9200A High Speed Vortex Blender reaches 48,000 rotations per minute, making Green Smoothies a piece of kale. I mean cake.

Blades

Ok, so we agree that a high engine power and many rotations per minute are great specs for blenders when it comes to high performance. But you always need to keep in mind the quality of the blades. Perfect results can be achieved only if the blades are arranged properly, if they are made from high-end materials and if the power transmission from the motor to the blades is flawless.

Contrary to popular belief, the blades don’t have to be sharp in a professional blender. Sharp blades are ripping and slicing nutrients and that can destroy the enzymes in the food – you don’t want that. Cheap blender brands need to make their blades sharp as their motors are very week. On the other hand, Optimum’s high-end blades are just breaking and mixing the ingredients, thus preserving enzymes in food and assuring maximum intake of nutrients.

So the power is not really in sharpness of the blades, but in the power of the motor, its speed and the way the blades are positioned.

As you can plainly see, a high-performance blender is a complex kitchen appliance – and this is exactly why it is more expensive than an usual blender.

2. Blender Jug

After focusing on technical specs and numbers, you also need to keep in mind the blender container.

Material

Your blender jug should be very easy to clean and not take the taste or the colour of the food you’re blending (try mixing beets in your morning smoothie and you will see what we mean here). You will sometimes find blender containers made from hardened glass, like the WMF Kult Pro. However, most professional brands are avoiding this and going for the often-used plastic Tritan (Triphenylmethan). The reason glass is more and more avoided these days is simple: glass weighs significantly more and is not easy to handle; moreover, it has a high risk of breaking – for example when accidentally a metal spoon is mixed in. Glass is also more sensitive to high temperatures, so making nut butters and heating soups would be out of the question.

There’s more to being healthy than eating clean and exercising plenty. You would also want to make sure that your chosen healthy ingredients will not become potentially dangerous for you during the cooking process. High-quality blender brands are aware of this and started to act accordingly: Vitamix, Optimum Omniblend or Bianco are offering their high-end products with “BPA-free” jugs, so no trace of BPA would end up in your morning glass of healthy smoothie or juice.

Bisphenol A (or BPA, on short) is a chemical compound with an important role in the production of plastic and resin. It has been proven that, in minor quantities, BPA can merge into food and drinks, if these are stored in containers made with Bisphenol A components. The actual side effects in this case are not adequately proven, as it often happens with many controversial chemical substances. Some experts have looked into a connection between BPA exposure and many conditions and, according to certain studies, exposure to BPA, even at low and short-term doses, is linked to a number of health problems. We’ve dedicated a whole article to this and you can read more about BPA and BPA-free products here.

Optimum’s team of engineers is devoted to making their high-end blender range as safe as possible for the public. Our brand is determined to always play it safe and respect our clients’ healthy lifestyle. That is why all the blenders in the exclusive Optimum blender range come with a top-of-the-line UL, CE and FDA approved Eastman Copolyester BPA-Free jug. So you could sit back, relax and focus on your awesome ingredients, rather than on chemical compounds.

Volume

Always keep in mind the capacity of the blending container. It is shown in litres and can go from 0,25 L for personal blenders, to high filling quantities of 2 L. The last one is mostly used in professional kitchens but also when you want to make smoothies for your whole family, nut butters or cake batters.

However, you need to consider that bigger is not necessarily better and keep in mind your family or business needs. If your blender container is too big, you would need to fill it properly with ingredients, or the blender blades will not reach them. Therefore, if you want to blend for yourself or for two persons, you can use a smaller container – you can try the Optimum NutriForce Extractor , that has both a 450L and a 1L jug. However if you have a bigger family (4-6 members) or if you plan on making spreads, batters and butters for some guests, a 2L container would be perfect – you can try the 2L Eastman Copolyester BPA-Free jug that comes with the Optimum G2.1 Platinum Series.
