Below, a manufacturer of egg beaters provides a detailed introduction to these machines. A vertical egg beater generally comprises a mixing bowl, a mixing unit, a drive mechanism, a lifting mechanism and a base. The mixing unit consists of a mixing head and mixing paddles, which come in three shapes: hook-shaped, mesh-shaped and spherical. Each shape is suited to different applications. The hook-shaped mixing paddle is suitable for mixing batter. The main components of a vertical dough mixer include the mixing bowl, mixing hook, drive mechanism, electrical control box and machine base. The mixing bowl rotates automatically once the dough-mixing cycle begins. It is worth noting the rotation mode of the stand mixer: the mixing bowl is firmly attached to the base; although it is removable, it remains fixed during operation, with the mixing arm rotating whilst the mixing bowl remains stationary. In other words, the stand mixer operates with unidirectional mixing. In contrast, the mixing hook of an upright dough mixer rotates within the mixing bowl driven by the drive mechanism; simultaneously, the mixing bowl itself also rotates under the drive of the mechanism. In other words, an upright dough mixer operates with bidirectional mixing (both the mixing hook and the mixing bowl are in a rotating state during operation). Hand Mixers Rotational Speed of Hand Mixers: Stand mixers are equipped with a transmission system; power from the motor is transmitted via a pulley and reduction gear to a speed control unit, where speed and direction are adjusted to perform various mixing tasks. As the viscosity of the ingredients mixed by hand mixers is generally lower than that of dough, the rotational speed of hand mixers is typically higher than that of stand mixers. It should be noted that upright mixers of different materials, models and brands often feature multi-speed settings (rather than a simple low-medium-high three-speed design); consequently, the appropriate speed settings vary from machine to machine. When using a mixer to knead dough, it is necessary to observe and test the settings repeatedly. Operating Efficiency: Both upright mixers and upright dough mixers are available in a range of capacity specifications. Different commercial establishments can select the appropriate model based on their specific needs. Bakeries, Western-style restaurants and pizzerias with high customer footfall should opt for larger-capacity equipment to ensure efficient dough production. It is worth noting that, due to differences in operating modes, even when the capacity is the same, a twin-action upright dough mixer has a greater mixing capacity than a single-action upright mixer. Furthermore, upright dough mixers operate more quietly than egg beaters.
