Two grinding principles

Stone grinder or roller refiner?

Both machines work with the same products: pralines, almond and hazelnut pastes, nuts. What changes is the way they grind: everything in a tank with the ARTINIBS, in passes between stone rollers with the RB.

30 kg tank

ARTINIBS stone grinder

Everything is ground in the tank: the granite stones turn continuously and refine the mass down to 22 microns.

Its strength: maximum fineness, with no handling

See the ARTINIBS

20–80 kg/h

RB refiner-grinders

The product passes between three stone rollers and falls into a tray: three passes are usually enough to obtain a paste.

Its strength: fast grinding, on demand

Roller refiner-grinders

RB refiner-grinders

The RB refiner-grinder grinds almonds, hazelnuts, pralines, nougatines, walnuts and gianduja. The product goes down between three basalt stone rollers and falls into a tray: you pass it through again, usually three times, to obtain a paste. Ideal for freshly ground homemade almond paste or almond powder.

What you make

Chocolate, pralines and nut pastes

Control your recipes from start to finish: you choose your beans and your nuts, and you make your own masses.

Cocoa beans

Bean-to-bar chocolate

The cocoa nibs are ground and then conched in the tank, until you get a fluid, even chocolate.

Ground praliné

Homemade pralines

Caramelised nuts ground in about two hours, to the texture you are looking for.

RB refiner-grinder

Almond pastes and powders

Freshly ground almonds and hazelnuts, as a powder or a paste, between the stone rollers.

ARTINIBS

How does a stone grinder work?

The granite stones turn continuously on a granite base: they slowly grind the cocoa mass or the nuts, while the temperature is controlled.

30–35 kg

1. Loading

The tank takes 30 to 35 kg of cocoa nibs or preparation to be ground.

Granite

2. Grinding

You set the stone pressure according to the texture you want. An infrared sensor and a thermostat keep the mass at temperature.

22 µm

3. Emptying

The tank tilts for emptying, then is simply washed with water.

Frequently asked questions

Grinders and refiners: your questions

The ARTINIBS stone grinder grinds everything in a tank: the granite stones turn continuously and refine the mass down to 22 microns. The RB refiner-grinder grinds in passes: the product goes down between three basalt stone rollers, falls into a tray, and you pass it through again, usually three times, to obtain a paste.

The ARTINIBS stone grinder. Loaded with 30 to 35 kg of cocoa nibs, it grinds and conches the mass on its granite stones. After 24 to 72 hours depending on the cocoa used, you get a fluid, even chocolate with a fineness below 22 microns.

Both machines are suitable, for the same products: only the method changes. With the ARTINIBS, pralines are ground in the tank in about 2 hours. With an RB refiner, almonds and hazelnuts pass between the stone rollers: three passes are usually enough to obtain a paste, a single one for a powder.

Three models: the RB5 grinds 20 kg/h, the RB6 40 kg/h and the RB8 80 kg/h. They run on 400 V three-phase, from 900 to 2,200 W.

Down to 22 microns. The stone pressure is set manually, which lets you adjust the fineness and texture to the recipe.

The tank tilts on a rotation system for emptying, then is washed with water. The contact area has no screws or bolts, which avoids any risk of contamination.
