What Is a Cold Press Juicer?

It's early. The kitchen is still half dark, the kettle hasn't started, and there's a bowl of apples, a few carrots and a knob of ginger on the counter. You switch on the juicer and it begins to turn, slowly, with a low, steady hum. A few minutes later there's a glass of juice in front of you, smooth and bright, and the house is still quiet.

That's the feeling a cold press juicer is built around. This guide explains what a cold press juicer is, how it works, and what it's like to live with one.

What is a cold press juicer?

A cold press juicer makes juice by pressing rather than cutting. Inside, a screw-shaped part called an auger turns slowly and presses fruit and vegetables against a fine strainer. Juice passes through the strainer and flows out the front. The pressed pulp is pushed out the side.

You'll also hear the names "slow juicer" and "masticating juicer." At home, they generally describe the same idea: a slow, steady press.

The Heartnoks Cold Press Juicer presses at 45–55 RPM. See each part move on our How It Works page.

How does a cold press juicer work?

1. You feed it

Produce goes into the feed chute at the top. The Heartnoks has a 6.5-inch wide feeding chute, so many fruits and vegetables need less pre-cutting. Feed slowly, one piece at a time, and guide them down with the pusher.

2. The auger presses

The auger turns slowly and draws the produce down, crushing and pressing it against the strainer.

3. Juice and pulp separate

Juice flows through the strainer and out of the juice outlet at the front. Pulp leaves through the pulp outlet at the side. You end up with a glass of juice in one place and the pulp in another.

4. If something catches

Sometimes a fibrous piece catches. The dial on the Heartnoks reads REV · O · ON. If something catches, switch to REV for a moment, then back to ON.

What it's like to use one

The sound

A slow press has a different rhythm. On the Heartnoks it's a low hum and the soft sound of produce being pressed, calm enough for a sleeping house.

The texture

Pressed juice tends to come out smooth, with a gentle body. Pour it into a glass and let it settle for a moment.

The pace

A cold press juicer asks you to slow down a little. You feed, you wait, you watch the glass fill. For many people, that's the point: a small, unhurried ritual before the day starts.

More than juice

One juicer, all seasons. Alongside fresh juice, the Heartnoks makes fruit sorbet and oat milk.

Sorbet on hot days

For sorbet, the setup changes in two small ways. Use the Sorbet filter instead of the juicing strainer, and close the juice outlet so the dessert comes out of the pulp outlet, with a bowl there. Freeze the fruit 8 hours or overnight, and thaw it about 5 minutes before pressing.

Oat milk anytime

Oat milk uses the same setup as juice. Soak rolled oats briefly, rinse them, and feed them slowly with cold water. Find recipes on our recipes page.

Setting it up

Setup takes a minute once you've done it once. From the Heartnoks manual:

  1. Set the juice container on the base, with FRONT facing you.
  2. Lower in the auger and give it a gentle turn until it settles.
  3. Fit the juicing strainer over the auger.
  4. Set the feed chute on top, with the lid open. Align the unlock mark on the chute with the ▲ on the container.
  5. Rotate the chute left until the lock mark lines up with the ▲. You'll feel it lock.
  6. Close the lid and place a glass under the juice outlet.

If it won't start

This is a safety design, and it's normal. The juicer only starts when the feed chute is locked, the filter is installed and the lid is fully closed. Check those three things, and that the auger and filter are fully seated.

Cleaning up

Cleanup takes about 3 minutes. Unlock and lift off the parts, empty the pulp, and rinse each piece under running water. Brush the strainer mesh clean. The removable parts are dishwasher-safe; the motor base is not. Wipe the motor base with a damp cloth only, and never put it in water.

Rinsing soon after use, before the pulp dries, makes the biggest difference.

A few honest notes

  • It's a slower process. That's by design.
  • Some prep still helps. Peel citrus, since the peel tastes bitter, and cut long, fibrous stalks like celery into shorter pieces.
  • Juice is best fresh. Homemade juice hasn't been pasteurized. The FDA advises keeping untreated juice refrigerated, so pour it into a clean, covered container and get it into the fridge right away if you're not drinking it now.
