A dust containment system is provided for containing, collecting and extracting airborne contaminants produced during the operation of a machine, such as a bread dough mixer. The containment system includes a hood to fit over the upper portion of a bread mixer to envelop the space above the mixing bowl in order to contain flour dust produced during dough mixing. A vacuum system may be attached to an exhaust port in the hood to create a negative pressure differential on the interior of the containment system and to extract airborne flour dust. A control access panel through the hood is provided to allow a user to operate the control switch of the bread mixer without removing the containment system from the machine.

The invention relates to a rotary shaft (23) for processing foodstuffs, wherein the rotary shaft (23) has a rotation axis and the rotary shaft comprises at least one tool (11). The at least one tool (11) extends along the rotation axis. The tool (11) further has an airfoil profile such that the tool comprises a leading edge, a trailing edge, an upper surface and a lower surface, wherein the leading edge and the trailing edge are different.

An implement attachment holder for a hand mixer includes a body defining opposed first and second surfaces and first and second mounting projections coupled with the body and extending away from the first surface of the body at respective first and second locations spaced apart at a first distance along a first direction. The attachment holder further includes a device retention projection extending away from the second surface of the body and partially along the first surface to at least partially overlie the first and second locations from which the first and second mounting projections extend. The device retention projection further defines at least three attachment channels extending in a second direction normal to the first direction at spaced-apart locations along the device retention projection.

A hydration chamber for dry ingredients is disclosed. The chamber has a metered ingredients feed, a diverter that distributes the ingredients within the chamber, and a spray nozzle for hydrating the ingredients. The spray may be varied to achieve different levels of hydration, such as for the manufacture of dough, batter, or other compositions. Process parameters, such as volume flow rate of the dry ingredients and the spray pressure can be varied.

The hydration apparatus includes an air augmentation feature that intersects the ingredients. The air augmentation inlet is positioned to cause turbulence in the ingredients prior to the ingredients passing a liquid discharge nozzle that hydrates them.

A mixing chamber for mixing a variety of dry ingredients with a liquid is disclosed. The mixing chamber has an accumulation chamber that evenly distributes ingredients as they pass a liquid spray nozzle, resulting in uniform hydration. The liquid may be sprayed at a variety of pressures to achieve varying levels of granule hydration to permit the manufacture of dough, batter, or other compositions. Even dry ingredients which are generally slow to absorb moisture may be rapidly and evenly hydrated without an excess of liquid. Process parameters, such as volume flow rate of the dry ingredients, can also be varied.

The invention relates to a discharge device (1) for the portion-wise discharge of a compact food mass from a kneading vat (3) arranged in a lifting tipper (2), which device comprises at least two cutting tools (13) each having at least two cutting edges (20) for cutting through or cutting up the compact food mass.

A household mixer appliance having a mixing container with an inner surface and an open top, a drive arrangement and a hook. The hook has a sole attachment portion which, when attached to the drive arrangement, abuts a first inner surface portion of the mixing container inner surface. The sole attachment portion is attachable to the drive arrangement via a through hole in the first inner surface portion such that the hook is rotatable around a substantially horizontal axis of rotation within the mixing container when the hook is attached to the drive arrangement.
