Presentation
The recognised know-how of Bertrand-Puma has been padded out over the years to enable bakers and pastry-makers to satisfy their specific needs better.
SPI spiral mixers offer unrivalled mixing quality, combining versatility and reliable heavy-duty capacity, for perfect respect of the dough and your work.
The SPI range consists of 5 models, with automatic or electromechanical control panels, with a capacity ranging from 3 to 200kg depending on the model.
Technical Datas
Focus on Mixing Quality
The regular movement of the spiral produces structured, smooth, even and homogeneous dough thanks to a succession of pushing, stretching and shearing movements.
These results are obtained by the spiral. Its shape, combined with the bowl’s geometry, has been designed to prevent the dough from rising along the tool, even when working in small capacity.
SPI spiral mixers ensure gentle mixing, without overheating, while respecting the steps required for perfect oxygenation.
A BOWL DESIGNED TO BOOST EFFICIENCY
The polished stainless steel bowl of SPI spiral mixers has been specially designed to ensure effective and quick mixing as well as optimal oxygenation of the dough by consecutive stretching, cutting and blowing.
Its flat base allows better collection of the flour on the sides and smooth mixing to obtain perfect dough.
TOUGHNESS, ERGONOMICS AND SAFETY
Toughness
Power transmission by belt requires no maintenance
Ergonomics
Adjustable feet stabilise the mixer
Safety
When the cover is open, the mixer automatically stops
Transmission by trapezoidal belts!
The trapezoidal shape of the belt drives produces excellent contact with the pulleys (1).
This silent solution offers very comfortable use and guarantees durability of the mechanism.
Perfect hygiene
The lacquered main body, anti-flour projection lid and stainless steel bowl are very easy to clean.
The height-adjustable feet guarantee excellent stability when working (2). The main body is mounted on wheels to be able to move it easily and for simple floor cleaning.
Safety above all!
The SPI range has a safety system that immediately closes the bowl when the lid is opened (3). The mixer then comes to a complete stop.
An action of the user is needed to start the cycle again in complete safety.
STOP FLOUR DUST!
When making bread, flour dust stays in suspension in the bakery’s atmosphere. This can cause asthma, unfortunately recognised as a common occupational disease among bakers.
To stop these sometimes chronic breathing problems among 25% of bakers, Bertrand-Puma has fitted its SPI mixers with a protective transparent plastic lid.
Anti-flour projection lids significantly reduce the emission of flour dust and of enzymes contained in certain types of flour during the initial minutes of mixing.
Completely transparent these lids are easy to clean and offer a permanent view of the dough, in all stages from kneading to fermentation. The whole lid can be opened to offer easy access to the bowl.
A NEW AND ATTRACTIVE DESIGN
The new ergonomic and modern design makes of the SPI spiral mixers a unique and recognizable piece of equipment.
The cover lid in thermoformed ABS is ideal for bakery applications thanks to its smooth surfaces and its resistance to blows and scratches.
The cover does not present any plane surface where the baker might be tempted to leave tools, thus preventing those from dropping into the bowl and damaging the machine during the mixing.
USER FRIENDLY
Clear and ergonomic, the Bertrand-Puma control panels are available in automatic version (EL models) or manual (EM models) throughout the SPI range. They allow effective and simple kneading management.
