How To Make Soy Milk With A Juicer? The Expert Method for Creamy Results

You bought a juicer for fresh orange juice and green smoothies. Then one morning you realize you have dried soybeans in the pantry and wonder: can this machine actually make soy milk? The short answer is yes, but the long answer matters more. Most people who try it once get a watery, beany-tasting liquid that separates in the fridge. That does not have to be your experience.

This article walks you through exactly how to make soy milk with a juicer — from bean prep to finished pitcher — so you get a product that equals or beats what you buy in cartons. We will cover why a juicer works differently than a blender, which beans to pick, the blanching step most recipes skip, and the one machine feature that makes the whole process dramatically easier.

If you have ever tried making soy milk in a blender and hated the clean-up, the juicer method solves that. It also delivers a cleaner mouthfeel because the pulp gets separated during extraction rather than needing a nut milk bag later. But there are trade-offs. Let us get into them.

One tool that simplifies the entire process is the Arcmira 8 in 1 Nut Milk Maker Machine. It combines soaking, grinding, heating, and straining in one unit, so you skip the juicer steps entirely if you want convenience. But for those who already own a good juicer, the manual method still produces excellent milk — and costs nothing extra.

Why Use a Juicer for Soy Milk?

A juicer separates liquid from solid fiber using centrifugal force or a slow auger. Soy milk is essentially a suspension of protein and fat in water. The solids — the okara — are the fiber-rich pulp. When you run soaked soybeans through a juicer, you get the liquid fraction immediately. That is a big time-saver compared to the blender method, where you have to blend, boil, then strain through cloth.

There are two types of juicers for this job. Centrifugal juicers work fast but introduce more air and heat, which can oxidize the milk and dull the flavor. Masticating (slow) juicers, especially those with a stainless steel auger, produce a colder, less aerated liquid. If you own a cold press juicer with stainless steel auger, you are in a better spot. The lower speed means less heating and less foam.

The main downside? A juicer cannot cook the milk. Raw soy milk contains trypsin inhibitors and lectins that need heat to break down. You must boil the extracted liquid after juicing. Do not skip this step — drinking uncooked soy milk can cause digestive upset.

Bean Selection and Prep That Actually Matters

Use dried soybeans, not fresh. Fresh (edamame) beans produce a grassy, thin milk. Look for yellow soybeans labeled for soy milk — they have a higher protein content and lower oil than green varieties. Organic is nice but not required.

Soaking is non-negotiable. Dry beans will destroy your juicer blades and yield almost no liquid. Soak for 8 to 12 hours at room temperature. Change the water once mid-soak. The beans should roughly double in size. If you live in a warm climate, soak in the fridge to avoid fermentation.

Here is the step most guides leave out: blanch the soaked beans for 3 minutes in boiling water. This deactivates the lipoxygenase enzyme responsible for that raw beany flavor. Pour the beans into boiling water, boil for exactly 3 minutes, then drain and rinse with cool water. The result is milk that tastes like the stuff from a good Asian market, not like wet cardboard. Test it once without blanching and once with — you will never skip it again.

Step-by-Step: Make Soy Milk With a Juicer

1. Soak and blanch 1 cup dried soybeans as described above. Drain well. Do not let them sit wet too long after blanching — the skins start to loosen and can clog the juicer.
2. Cold water ratio. For every cup of dried beans (now about 2 cups soaked), use 4 cups of cold water. That gives a traditional 4:1 dilution. For creamier milk, use 3 cups water. For thinner, use 5. Write down what you like so you can repeat it.
3. Feed beans and water together. Do not feed dry beans then pour water separately. Alternate a handful of beans with a splash of water into the juicer chute. This keeps the auger lubricated and prevents jamming. If your juicer has a low-speed setting, use it.
4. Collect the milk. The liquid comes out the spout almost clear but will turn milky as the fine solids mix in. You will get roughly 4 to 5 cups of raw milk from 1 cup dry beans.
5. Strain again (optional but recommended). Even with a good juicer, some fine grit passes through. Strain through a cheesecloth or a nut milk bag. If you used a masticating juicer, the amount of sediment is tiny — you might skip this step entirely for a rustic texture.
6. Boil the milk. Pour the raw milk into a heavy-bottomed pot. Bring to a gentle boil over medium heat, stirring frequently. Soy milk scorches fast. Once it reaches a rolling boil, reduce heat and simmer for 8 to 10 minutes. Watch for foaming — it can overflow quickly. Skim off the foam if you want a cleaner finish.
7. Cool and store. Let the milk cool to room temperature, then refrigerate in a sealed glass jar. It keeps for 4 to 5 days. Shake well before pouring because natural separation happens.

Juicer vs Blender vs Dedicated Machine: Which Is Better?

Each method has trade-offs in time, texture, and cleanup. Here is a direct comparison:

If you already own a decent juicer, the method above works well. But if you make plant milk more than twice a week, a dedicated machine like the Arcmira 8 in 1 cuts the work by about half because it heats the milk during blending — no separate boiling step. The self-clean feature alone saves ten minutes of scrubbing.

Troubleshooting Common Problems

Milk tastes beany even after blanching? You might have boiled the milk too long. Overcooking caramelizes the natural sugars. Simmer 8 minutes max for raw beans. Also, older beans produce more off-flavors. Buy beans with a harvest date within six months.

Juicer clogged while running? The bean skins from blanching are slippery. Rinse the beans thoroughly after blanching. If your juicer has a reverse function, use it. Do not force the plunger. For centrifugal juicers, cut the feed into smaller handfuls.

Separation in the fridge is normal. Commercial soy milk contains stabilizers like carrageenan or gellan gum. Homemade milk naturally separates. A quick shake or stir brings it back. If you want a more stable emulsion, add a pinch of salt and a teaspoon of sunflower lecithin before boiling.

Foam overflow on the stove. Use a pot at least twice the volume of the milk. Stir constantly once it approaches boil. A drop of coconut oil on the surface helps break foam. Also, do not cover the pot — trapped steam makes foam worse.

Frequently Asked Questions

Can I use a centrifugal juicer for soy milk?

Yes, but expect more foam and a slightly hotter extraction. The high-speed spinning aerates the milk and can denature some proteins, making it thinner. Counteract by using very cold water and running the juicer at its lowest setting if available. Clean the filter basket immediately after use — soybean residue dries into a cement-like film.

Do I need to remove the bean skins before juicing?

Not necessary if you blanch. Blanching loosens the skins, and most will be caught in the pulp basket. A few skins might slip through, but they are edible and will be strained out. If you find the skins bitter, rub the beans between towels after blanching to remove the hulls, then rinse.

How long does homemade soy milk last in the fridge?

4 to 5 days in a clean glass container with a tight lid. After day 5, the flavor turns sour even if it smells fine. Do not freeze it — thawing causes severe separation that no amount of shaking fixes. Make smaller batches instead.

Is soy milk from a juicer cheaper than store-bought?

Dried soybeans cost roughly $1.50 per pound, and one pound yields about 4 to 5 quarts of milk. That works out to roughly $0.40 per quart, far less than organic store brands at $3–4 per quart. You pay in time and elbow grease, not dollars.

Can I add flavor during the juicing process?

Do not put sugar, vanilla, or salt into the juicer — they will gum up the works. Flavor the milk after boiling. For vanilla soy milk, stir in a split vanilla bean while the milk cools. For a sweet version, add a tablespoon of maple syrup or honey after boiling, then chill.

What to Do Next

• Start with 1 cup dried yellow soybeans. Soak 8 hours, blanch 3 minutes, then juice with cold water at a 4:1 ratio.
• Boil the extracted milk for 8 minutes stirring constantly. Skim foam. Cool fast in an ice bath for best flavor.
• Store in the fridge for no more than 5 days. Shake before each use.
• If you own a slow juicer with a stainless steel auger, you will get the cleanest milk with the least sediment. A centrifugal juicer works too but requires a second strain.
• Consider a dedicated milk maker if you want to skip the separate boiling and scrubbing. The Arcmira model listed above handles both grinding and heating in one cycle and includes a self-clean mode that actually works — no need to disassemble halves of soy fiber every morning.
• Experiment with ratios. A 3:1 water-to-bean ratio gives a rich milk that froths well for lattes. A 5:1 ratio produces a lighter milk better for cereal.
• Reserve the okara (pulp). Use it in veggie burgers, muffins, or as a gluten-free binder in meatballs. It freezes well for up to three months.
