Blender Buying Guide — RPM, RPM, RPM: The Most Important Thing, Repeated Three Times

About a year ago, my wife bought a high-end blender for our home. At the time, I thought it was a waste of money — wouldn’t a regular juicer do the job? But after actually using it, I completely changed my mind. From daily soy milk and milkshakes to soups and sauces, and even grinding spices — the blender has become our most-used kitchen appliance. The soy milk it makes is way more fragrant than store-bought, with absolutely no residue. My mom, who was skeptical at first, tried our soy milk and immediately went out and bought the same model. So today I’m sharing a comprehensive blender buying guide — from core parameters to brand selection — to help you make the right choice.

Heating vs Non-Heating Blenders: Which One Is Right for You?

The first big decision is whether to buy a blender with heating function or without. This determines what you can make and how much you’ll pay.

Type	How It Works	Pros	Cons	Best For	Price Range
Heating Blender	Built-in heating element cooks ingredients while blending	One-step soy milk, soup, porridge; time-saving; no extra pot needed	Higher price; prone to burnt residue with thick ingredients; can’t handle hot ingredients (safety lock)	Chinese households, those who frequently make soy milk, soups, porridge; one-machine multifunction	400-2000 yuan
Non-Heating Blender	Pure blending; ingredients need to be heated/cooked first	Higher blending speed; Frees up recipe possibilities (smoothies, protein shakes); no burnt bottom; easier to clean	Requires separate heating; one extra step for soy milk	Health-conscious, smoothie fans, fitness enthusiasts wanting more control	300-6000 yuan

My recommendation: Most Chinese families should choose a heating blender. The ability to make hot soy milk and soups with one button is incredibly convenient for breakfast. In the morning, just toss in soaked soybeans and water, press the button, and 25 minutes later you have piping hot, smooth soy milk — no extra pot needed. Non-heating blenders require you to cook the soybeans first and then blend, adding an extra step. However, if you primarily make smoothies, milkshakes, and cold drinks, a non-heating blender is the way to go — the higher speed and more durable motor will serve you better long-term.

Motor Speed: The Core Metric

Motor speed is the most important performance metric for a blender. It directly determines how fine the ingredients are ground. The unit is revolutions per minute (rpm).

Speed Range	Performance	Best For	Can It Handle These Tasks
15,000-20,000 rpm	Entry-level, mediocre grinding fineness	Basic milkshakes, fruit smoothies	Juice: good; Soy milk: coarse; Spices: no
20,000-25,000 rpm	Mid-range, decent grinding fineness	Soy milk without filtering, soups, sauces	Juice: very good; Soy milk: fine enough; Spices: limited
25,000-30,000 rpm	High-speed, fine grinding	High-fineness soy milk, nut butters, smoothies	Juice: excellent; Soy milk: residue-free; Spices: passable
30,000+ rpm	Professional grade, ultra-fine grinding	Professional use, nut flours, ice crushing, fibrous juice	All tasks excellent; truly silky texture

My advice: Choose a blender with 25,000 rpm or higher. Below 20,000 rpm, the blended texture is noticeably coarse. Soy milk made with an entry-level blender requires filtering — which defeats the purpose of buying a high-end blender in the first place. At 25,000-30,000 rpm, soy milk is smooth enough without filtering, and nut butters and soups have a pleasant mouthfeel. If your budget allows, 30,000+ rpm offers professional-grade fineness.

Blade and Jar Design: Key to Durability and Grinding

Blade material and design: Mainstream blender blades are made of stainless steel (304 or 301 grade). High-end models use imported Japanese steel, which is harder and more durable. The number of blade tips (4, 6, 8) affects grinding efficiency. In general, 6- or 8-tip blades provide more contact points and finer grinding. The blade design also matters — some have special serrated or curved edges to create eddy currents that push ingredients toward the blades for more uniform blending.

Jar material: Plastic (Tritan) is lightweight, shatter-resistant, and suitable for most blending tasks. Glass jars are heavier but odor-resistant, though they break easily. Stainless steel jars are durable but not transparent. For home use, Tritan plastic is the best balance of weight, safety, and clarity. Make sure it’s BPA-free.

Jar capacity: 1.0-1.2L is sufficient for 1-2 people. 1.5-1.75L suits families of 3-4. For larger quantities, choose 2.0L+. My recommendation for a family of three is 1.5L — enough for a full batch of soy milk for everyone, while still fitting on the counter.

Noise Level: Pay Attention If You Have Neighbors or a Baby

Blenders are inherently noisy because of the high-speed motor. However, there are significant differences in noise levels across models. Here are some noise-reducing features:

Soundproof enclosure: Some high-end models come with an outer shell that covers the jar, significantly reducing noise. These enclosures can reduce perceived noise by 10-15dB.

Inverter motor: Instead of running at full speed continuously, inverter motors adjust speed smoothly, which helps reduce noise peaks.

Vibration-dampening base: Silicone pads and rubber feet absorb vibration and reduce resonance noise.

Slow-start function: Starts at low speed and gradually ramps up, avoiding the loud initial jolt.

If noise is a concern, look for models specifically marketed as “silent” or “low-noise” — but remember that no blender is truly silent. Expect 70-80dB at maximum speed, comparable to a vacuum cleaner. Some premium models can reduce noise to 60-70dB, which is manageable.

Joyoung is the market leader in blenders, pioneering the “soy milk maker” category. The L18-Y915S is my top value recommendation — for under 700 yuan, you get 32,000 rpm, heating, 8-tip blades, and a 1.75L capacity. Hot soy milk in one touch. Joyoung’s智能食谱 ecosystem is also extensive, offering dozens of recipes through the app. The Y3 is Joyoung’s mid-range offering with a low-noise design, ideal if noise is a concern.

Midea has strong offerings in both heating and non-heating categories. The PB12Power304 is an excellent heating model with 36,000 rpm — one of the highest speeds in the heating category. The MJ-PB80X2-186 is a high-speed non-heating model at 42,000 rpm, great for smoothie enthusiasts.

Supor blenders are known for their build quality. The SP815S is a well-rounded heating model, and the JP96L-GPro is a premium non-heating option with smart sensor technology that automatically adjusts blending time based on ingredient texture.

Westinghouse and Vitamix represent the premium end of the blender market. Westinghouse’s D3 is a strong mid-to-high-end non-heating blender at around 1,600 yuan. Vitamix’s A3500 is the ultimate professional blender — used in cafes and smoothie shops worldwide. The build quality is exceptional, backed by a 10-year motor warranty. If you’re a serious smoothie maker or want a blender that could last two decades, Vitamix is the gold standard. The downside: prices start at 6,000+ yuan and it has no heating function.

Key Features: Automatic Cleaning, Intelligent Recipes, and Timer

Automatic cleaning: Most mid-to-high-end blenders now have a one-touch cleaning function. After blending, just add water and a drop of detergent, press the cleaning button, and the machine runs a short cycle to clean itself. This is very convenient for daily maintenance. However, thoroughly cleaning under the blade seal still requires occasional manual disassembly.

Intelligent recipes: Some blenders connect to a mobile app with dozens or even hundreds of built-in recipes. The machine automatically adjusts speed and time based on the selected recipe. The Joyoung app, in particular, has a rich recipe library with step-by-step guidance.

Timer / delay start: This is especially useful for making soy milk for breakfast. Set the delay timer the night before, and the machine starts blending just before you wake up — piping hot soy milk waiting for you. Most heating blenders above 500 yuan offer this feature.

Blender Buying Plans for Different Budgets

Under $70 (under 500 yuan): Entry-Level

In this range, look for heating blenders with around 25,000 rpm. Joyoung’s entry models (like the DJ12B-D610SG) or Midea’s budget offerings. Note that the grinding fineness won’t be as good, and you may need to filter soy milk. For basic smoothies and soups, they’re sufficient.

$70-140 (500-1000 yuan): Value Sweet Spot

This is my recommended range for most families. Joyoung L18-Y915S (around 700 yuan) or Supor SP815S (around 800 yuan) give you 30,000+ rpm, heating, automatic cleaning, and intelligent recipes. They handle daily soy milk, soups, and smoothies with ease.

$140-280 (1000-2000 yuan): Mid-to-High End

This range offers better build quality and some premium features. Joyoung Y3 (around 1,200 yuan) with low noise, Midea PB12Power304 (around 1,000 yuan) with 36,000 rpm, or Westinghouse D3 (around 1,600 yuan) for a non-heating option. You also get better jar materials and warranty terms.

$420+ (3000 yuan+): Professional Grade

Vitamix A3500 is the undisputed king. If you drink smoothies daily or run a small cafe, the investment is well worth it. The 10-year motor warranty and professional-grade build make it a once-in-a-lifetime purchase.
