A detachable rib for use in a mixing bowl that provides an obstacle for ingredients being driven around the inside of a mixing bowl. The rib comprises a blade configured to extend in an axial direction along an inner surface of the mixing bowl; and an attachment formation for engaging with a corresponding formation of the mixing bowl, the engagement securing the rib against circumferential movement in at least one rotational direction; such that in use the blade interrupts a path of food being driven around the mixing bowl.

A stirrer apparatus, in particular for a usage in crystallizers, comprises a stirrer shaft, with at least one first blade element, which is held at the stirrer shaft and is configured for a mixing of at least one material that is to be mixed, and comprises at least one second blade element, which is held at the stirrer shaft and is configured to keep at least a proximity around the stirrer shaft free from material deposit and/or encrustations,

wherein the stirrer apparatus further comprises at least one stirring blade with a front side and a rear side, which comprises the first blade element and the second blade element.

Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks. Some machines include a refrigeration system to cool food or drink in a pod. The machines include an evaporator defining a receptacle sized to receive the pod. The evaporator includes an inlet port to receive refrigerant and an outlet port to discharge refrigerant.
