Industrial double-arm horizontal mixers
Advanced performance and versatility for tough and complex doughs.
Silvestri horizontal industrial mixers with double Z-shaped mixing arms are designed to offer high performance and speed in the production of dough for cookies, crackers, and leavened doughs in general.
They are especially suitable for mixing very stiff doughs like gingerbread or dog food. They are extremely adaptable, with the ability to separately adjust the speeds of the two mixers, allowing for excellent doughs to be obtained in shorter times.

The supporting structures are treated with a polyurethane enamel to ensure resistance and durability over time. Increasingly, we supply our machines with a structure entirely made of AISI 304 stainless steel. The protective panels are always provided in stainless steel and can be easily opened or removed, allowing access for maintenance operations.
The containment tanks are made of AISI 304 stainless steel and include a forced circulation system for the cooling and heating liquid, ensuring precise control of the dough temperature. The latter is constantly monitored by a PT100 sensor, ensuring optimal conditions at every stage of the production process.
The dough mixing takes place through two Z-shaped mixing arms rotating in opposite directions, ensuring high homogeneity of the ingredients. The absence of a central passing shaft facilitates the discharge of the finished dough and makes cleaning and sanitizing the bowl easier.
The mixing arms, made of cast stainless steel, are driven by a mechanical gear reducer in an oil bath, ensuring robustness and durability over time.
Each arm is operated independently with the ability to adjust the mixing speeds differently between the two axes, making the solution very flexible and adaptable even to the most demanding doughs.
Our machines are equipped with a sealing system using food-grade polyurethane lip seals, which ensure the dough does not escape from the mixing bowl during operation, even with particularly abrasive ingredients.
The seals can be removed from the outside without having to disassemble the machine's mechanics, saving considerable time and resources.
The mixing bowl is equipped with a mechanical tilting system with gear wheels that allows an inclination of up to 150°, ensuring efficient and complete discharge of the dough. For even more versatile use, a mechanism is available which allows double tilting, both front for dough discharge and rear for manual loading of minor ingredients and cleaning operations.
Additionally, the bowl can be stopped in any position, allowing the addition of ingredients during the mixing process for optimal production flexibility.
The bowl is equipped with a lid with a dust-proof rubber seal, designed to keep the work environment clean and safe. The lid also includes connections for automatic ingredient loading and, upon request, a practical opening hatch that allows manual loading from above, ensuring maximum operational versatility.
For the double-tilting bowl versions, the upper lid is liftable through pneumatic actuators, which still ensure dust-tightness during ingredient loading and dough mixing.
The main gear motor of our industrial horizontal mixers with double arms transmits the movement to the mixing arm reducer through gears, independently for each axis. The control through inverter allows the mixing speed to be adjusted between 15 and 60 rpm, providing maximum flexibility of solutions based on the product to be mixed.
The control panel of the industrial horizontal mixers with double arms, located at the front of the mixer, is equipped with a touch screen and a PLC for managing automatic cycles. A recipe control option is also available for even more precise management.

Frequently Asked Questions about Industrial Horizontal Mixers with Double Arms
- Efficient and Homogeneous Mixing: Thanks to the double-arm system with symmetrically arranged "Sigma" blades operating at differential speeds, Silvestri's mixers ensure optimal cross-mixing in a short time. This guarantees that all ingredients are mixed uniformly, improving the dough quality.
- Versatility: Silvestri's mixers are suitable for a wide range of doughs, including doughs for cookies, crackers, pretzels, soft biscuits, rusks, and gingerbread. This versatility makes them ideal for various industrial applications.
- Robustness and Durability: CBuilt with high-quality materials such as stainless steel, Silvestri's mixers are designed to last over time and withstand wear. The bowl is equipped with a double jacket for water cooling, ensuring an optimal temperature during mixing.
- Precise Control: The touch screen operator panel allows precise operation and control of the mixer, displaying the mixing time, dough temperature, and energy consumption. The PLC memory can store up to 500 processes (recipes), improving production efficiency and repeatability.
- Dough Type: These mixers are ideal for a variety of doughs, including cookies, crackers, pretzels, soft biscuits, rusks, and gingerbread.
- Processing Capacity: Assess the required processing capacity for your production needs; Silvestri's mixers range from 400 kg to 1500 kg.
- Materials and Construction: Ensure the machine is made from high-quality materials and meets safety standards.
- Support and Maintenance: Check the after-sales support provided by the manufacturer, including maintenance services and spare parts availability.
- Control and Automation: Our machines feature advanced control systems with touch screen operator panels and PLCs capable of managing recipes and potentially automating ingredient loading.
