The Biscuit Dough Kneader is a versatile, commercial-grade spiral mixer designed specifically for bakery operations, including the preparation of biscuit, cookie, bread, pizza, cake, and pastry doughs. This machine efficiently kneads and mixes ingredients to achieve a smooth, elastic consistency, saving time and labor in high-volume production environments like hotels, restaurants, caterers, and industrial kitchens. It features a robust spiral hook design that ensures even mixing without overworking the dough, preserving texture and quality for biscuits and other baked goods.
Available in multiple capacities—5 kg, 10 kg, 20 kg, 50 kg, and 100 kg—the kneader scales from small-batch home or startup use to large-scale commercial production. Capacities refer to the maximum dough output per batch (flour weight basis), with the machine’s bowl volume adjusted accordingly.

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.
