Dough mixer SIGMA SILVER-VE-300HD

The SIGMA SILVER LINE 400 L is a spiral mixer, article number SILVER-VE-300HD.

This type of mixer operates by using a spiral-shaped hook to knead dough. The hook rotates within a bowl, drawing the dough upwards and folding it back down, mimicking the action of hand kneading but at a much greater scale and speed. The motor powering the spiral is designed for high torque to handle dense doughs. In this model, the bowl itself also rotates, driven by friction wheels and an independent motor. This bowl rotation can be reversed, aiding in the dough mixing process.

To remove the 400 L bowl, a hydraulic system with a large piston and an independent station is used to open and close the machine, allowing the bowl to be withdrawn. During the kneading cycle, the mixer is secured by an electromagnetic system.

The control panel is situated on the right side of the unit and includes switches for opening and closing the machine. The mixing process is managed by two programmable timers, which control both the 1st and 2nd speeds of operation automatically. The electrical components are housed within a watertight box that features an antidust pressurisation system.

The mixer has a power rating of 18.75 kW and operates on a 400 V, 3-phase electrical supply. Its dimensions are 1350 mm in length, 2000 mm in width, and 1950 mm in height. The total weight of the unit is 1038 kg.

Cleaning and upkeep would involve regular cleaning of the removable bowl and the spiral hook. The hydraulic system and electromagnetic locking mechanism would require periodic checks as per manufacturer guidelines.
