Why gravity rather than a pump
From our experience, four reasons speak for it:
- The strong, tangy taste needs less air
- Many yogurt mixes are too heavy for a pump
- With a lot of air, yogurt becomes unstable
- In self-service by weight, dense ice cream sits better in the cup and on the scale
The Nissei models
They are built like the Nissei soft serve machines, only without the pump.

Pasteurisation and yogurt cultures
The Nissei frozen yogurt series pasteurises the mix inside the machine; according to Nissei it is taken apart and cleaned only every six weeks. Heating inactivates live cultures in the mix, and fresh mix brings new ones. If you want to advertise live cultures, clear that with the maker of the mix first.
Self-service
According to Nissei all three models are available with self-service as an option. There the guest pays by weight, and that is exactly why density counts: sell watery yogurt by weight and guests soon feel short-changed.
Can a gravity machine make soft serve too?
Yes. It turns out denser and stronger than from a pump, which goes well with matcha or premium recipes and with restaurants that offer ice cream as an extra. A machine cannot be converted, though: it is built either with a pump or with gravity feed. More in the guide Pump or gravity.

Frequently asked questions
Can I make frozen yogurt in a soft serve machine with a pump?
With some mixes yes, but many yogurt mixes are too heavy for a pump. For frozen yogurt as the main product we recommend a gravity machine.
How much space does a frozen yogurt machine need?
According to Nissei the Compact Frozen Yogurt measures 87 × 29 × 74 cm (height, width, depth) and weighs 84 kg.
Does Spaceman build gravity machines too?
Yes. Spaceman builds models with a pump and models with gravity feed; we work out together which one fits.
