Mix & carbonate

Soda Blender: the Machine That Carbonates the Drink | 4°

A soda maker carbonates water. A soda blender carbonates what you actually want to drink. The difference sounds small until you try to sell a water-only machine into a juice market.

Written by the 4° engineering team · Foshan, China

First, the word is used two ways

Sense 1: a blender plus a soda maker — two appliances, one making purée, the other adding gas. Sense 2: one machine that carbonates the drink itself. If you searched this term because you want sense 2, you are in the right place. If you want sense 1, you want a kitchen appliance we do not make.

We build sense 2. On seven of our model lines the machine will carbonate juice, tea, syrup and fruit directly in the bottle — the same body that dispenses still water when you do not press the button.

Why a water-only machine is hard to sell in some markets

Sparkling water is a habit in some countries and a curiosity in others. Outside the 2012–2018 boom the category has never been large on its own, and the words people use for it — sparkling machine, soda maker — are searched in modest volumes by mixed audiences.

Carbonating the drink changes that arithmetic. In markets where fruit juice, tea and sweetened drinks are everyday purchases, "make it sparkling" is an upgrade to something the customer already buys, not a new appliance category they have to be taught. That is a much shorter conversation.

What our mix line actually carbonates

Seven models — SHANG, SONG, SING, SHANG-2, EDGE, WALL-SERIES and SMARTZZI — carbonate far more than water:

  • Juices and nectars, fruit, vegetable and herbal infusions
  • Liquor and cocktails
  • Carbonation powder or liquid mixes — the syrup route
  • Tea, coffee, cream and oil
  • Flat soda and beer, re-carbonated

The classic G2 is a water machine and G3 is its refresh — we say so rather than promise more. Foaming, pulp and cleaning limits are set out in the manual for each model; if you tell us the drink, we will tell you which model handles it and how it has to be cleaned.

The line grew one problem at a time

It is worth knowing why there are seven, because the differences are answers to real objections — which is usually what a buyer is actually evaluating.

Model The problem it answers
SHANG The first one: smallest footprint, and the original one-way air patent
SONG The best seller — because of a more durable button and a steadier base
SING The bottle was too tall for the fridge. Click & Hang, and smaller bottles
SHANG-2 Same footprint as SHANG, but a conventional, firm press-down button
EDGE SONG in stainless steel — for the buyer who wants it to look like an appliance
WALL-SERIES There is no counter left. It mounts on the wall
SMARTZZI Take the hand out of it: a microcontroller sets the CO₂ volume and the release time

What every generation shares: a 17 bar pressure-rated bottle, the 1 L bottle (800 ml fill line), up to +30% dissolution efficiency, and two-phase release — slow then fast, so nothing sprays when you open it.

What to specify before you ask for a price

  1. The drink. Sugar, pulp, fat and alcohol all change the carbonation behaviour.
  2. The bottle. Which of 350 / 500 / 700 / 800 ml · 1 L your market expects, and whether it must fit a fridge.
  3. The counter. How much footprint you have — this is what decides SHANG versus WALL-SERIES.
  4. Manual or electronic. SMARTZZI if your market will pay for one-button consistency.
  5. Cleaning. What the user has to do between drinks, and how the model makes that easy.

Where the category sits

We describe our machines as counter-top water dispensers — the appliance that stands on the worktop and gives you chilled still water every day — with sparkling as the plus-one feature on top. A soda blender is the same idea pushed further: the machine is the standard appliance, and what it can carbonate is the reason to choose yours over the machine next to it on the shelf.

Common questions

Is a soda blender the same as a soda maker?
No, and the difference is the point. A soda maker carbonates water. A soda blender carbonates the drink — juice, nectar, tea, coffee, syrup mixes, fruit, even cocktails. In the trade the word is used loosely: some people mean "blender plus soda maker, two appliances", and some mean one machine that does both. We build the second kind: the same body dispenses still water and carbonates whatever is in the bottle.
Which drinks can your machines carbonate?
On the mix-and-carbonate line — SHANG, SONG, SING, SHANG-2, EDGE, WALL-SERIES and SMARTZZI — juices, nectar, fruit, vegetable and herbal infusions, liquor and cocktails, carbonation powder or liquid mixes, tea, coffee, cream and oil, and they can re-carbonate flat soda and beer. The classic G2 and G3 are water machines; we say so rather than promise more. Foaming, pulp and cleaning limits are covered in the manual for each model.
Is a soda blender a consumer product or a commercial one?
Both, depending on the model and the carton. The mix line is sold as a counter-top appliance for home use, but the same machines go into cafés, juice bars and on-tap drink stations — WALL-SERIES in particular exists because the counter is full. If your market is commercial, tell us and we will quote the model that suits the duty cycle.
Do I need my own syrup or can you supply it?
We build the hardware: the machine, the bottle, the carbonation and release system. Syrup formulation is your side — but the machine has to work with yours. Send us the drink (or its specification) and we will tell you which model handles it, what pressure and what cleaning procedure it needs.
How does this fit a wider product line?
That is the reason we talk about counter-top water dispensers rather than soda makers. A machine that dispenses chilled still water every day is a standard appliance your buyers already stock; the carbonation — the "soda blender" part — is the plus-one feature that makes yours the one they choose. Same body, wider shelf, and in this case a genuinely wider drink list.
