The Biscuit Dough Mixer is a heavy-duty industrial machine designed for efficient and uniform mixing of biscuit dough in commercial baking operations. It is particularly suited for producing a variety of biscuit types, including short dough (e.g., cream biscuit shells, glucose, tiger biscuits), hard dough (e.g., Marie, Petit Beurre), and fermented dough (e.g., Monaco, Krack-Jack, Snax). Available in batch capacities of 150 kg, 200 kg, 300 kg, 500 kg, and 1000 kg (based on dough output per cycle), this mixer ensures consistent gluten development, optimal hydration, and smooth texture for high-volume production lines. Capacities typically refer to the final dough weight per batch, with flour input ranging from approximately 75-500 kg depending on the model and dough type (soft or hard).

Key Features
-
Mixing Mechanism: Equipped with Z-arm or sigma-type blades that rotate at differential speeds (e.g., 20-40 RPM) in opposite directions for thorough kneading without overheating the dough. This design prevents dough sticking and promotes hygiene.
-
Construction: Made from food-grade stainless steel for contact parts, with cast iron bases for durability. Leak-proof seals, oil glands, and a fully enclosed chamber minimize dust ingress and ensure safety.
-
Tilting System: Hydraulic or electric tilting up to 90-135° for easy unloading into downstream equipment like extruders or sheeters. Larger models feature hydraulic systems for quick operation.
-
Optional Enhancements: Jacket for heating/cooling (via steam or water circulation) to control dough temperature; variable speed controls; energy management systems (EMS) for time- or temperature-based mixing cycles.
-
Power and Dimensions: Typically 5-15 HP motors (voltage: 110-440V, 3-phase); dimensions scale with capacity. Weight: 500-2000 kg.
Applications and Benefits
-
Versatility: Ideal for biscuit, cookie, cracker, and snack production lines; also adaptable for mixing bechamel sauce, polymers, or other viscous food pastes.
-
Hygiene & Compliance: GMP-compliant design with easy-to-clean surfaces; no through-shafts to avoid contamination.
-
Cost Efficiency: Reduces mix cycle times and labor; durable components minimize maintenance over the machine’s lifespan (typically 10+ years).
-
Customization: Available in horizontal (for dry/shortbread biscuits) or planetary (for creams/sponge) configurations; integration with automated feeding systems.

Process Operation of Biscuit Dough Kneader
In Sigma mixer tangential action of mixing and kneading obtained by ‘Z’ type (SIGMA) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from one end to another end. Discharge of the finished product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw beside the container.
The mixing action is a combination of bulk movement, stretching, folding, dividing, and recombining of the material. The shearing & tearing action of the material against blades and the side walls causes size reduction of the solids. After the time period required for sterilizing the batch has elapsed, the heating circuit shuts of the pneumatics damper (exhaust) opens and cooling operation commences.
In the tangential design, the blades rotate in the trough meeting tangentially. The front blade generally rotates faster than the rear blade usually in the ratio of 3:2. Tangential blades are generally used for material of higher viscosities such as adhesives, rubber compounds, flush colors, dyes, and pigments.
In the overlapping design, the blades overlap above the saddle of the container. Due to the overlapping action, it is necessary that the relative position of the two blades is unchanged, and as a result, both the blades rotate at the same speed. Materials that flow freely or creep down into the blades are mixed using the overlapping blade action. This design offers a faster interchange of material from one blade compartment of the mixer to the other. Overlapping blade action is used for materials of lighter viscosities such as carbon pastes, clay coating, creams, and ointments. The overlapping blade produces a lower kneading and shearing compared to the tangential blade action.
