HIGH SPEED HORIZONTAL MIXER (HSM)
Our high speed horizontal mixers are suitable for the production of any type of dough for hard and soft biscuits, cookies, crackers, snacks, soft dough etc.
Dough mixing is performed by a rotating mixing arm, which has an especially drop-shaped profile that SILVESTRI has designed on purpose so as to guarantee high homogenization of the ingredients. The lack of the central cross shaft helps either the easy discharge of the dough and the cleaning / hygiene of the bowl.
The casting stainless steel mixing arm is driven by an oil-dipped mechanic reduction gear.
The main build of the mixer is painted with polyurethane enamel painting and is protected by stainless-steel coverings which are either removable or movable in order to enable components inspection and / or maintenance.
The dough bowl is AISI 304 stainless steel made and is provided with a jacket all around its shape for the forced circulation of cooling / heating liquid. The dough temperature control is measured by a PT100 sensor.
Bowl tilting can be performed up to 160° by hydraulic cylinders while double tilting (forward and backward) a mechanical device with toothed gear is provided. The bowl tipping can always be stopped in any position to let hand addition of minor ingredients.
The bowl is topped by a fixed lid with FDA powder-proof rubber gasket, and is manufactured according to customer’s requirements with connections for automatic loading of solid and liquid ingredients and / or openable door for addition of minor ingredients.
The main motor transmission is operated through V-shaped trapezoidal belts in order to smoothen sudden tensions in the mixing process. Available solutions are single-polarity motor controlled by frequency inverter with adjustable speed from 15 to 60 rpm or double-polarity motor with 2 fixed speed.
The control panel on the front of the machinery is provided with touch screen and PLC for automatic cycle (recipe management on option) or with timer and push buttons for manual command.
The switchboard is IP66stainless steel cabinet hold into the machine’s frame in compliance with the most recent safety regulations.
