     DETAILED DESCRIPTION 
       [0009]    Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the scope of the disclosure. 
         [0010]    Several definitions that apply throughout this document will now be presented. “Circulating” means agitating, blending or mixing of one or more fluids. Hence a “circulator” is a device which can be configured to agitate, blend or mix a fluid. Fluids will be understood to comprise liquids. “Coupled” is defined as connected, whether directly or indirectly through intervening components and is not necessarily limited to physical connections. Coupled devices are devices which are in signal communication with one another. “Connected” means directly connected or indirectly connected. 
         [0011]    Broadly speaking, this disclosure relates to sous-vide circulator cookers for cooking food. 
         [0012]    In at least one embodiment, a sous-vide circulator cooker has a speaker or other suitable alert device connected to the controller in the control head to sound audible alarms when the bath fluid has reached cooking temperature. 
         [0013]    In at least one embodiment, the speaker can also be a single tone buzzer. 
         [0014]    In at least embodiment, a sous-vide circulator alarm&#39;s controller can be recognize the difference between normal heating and user induced temperature changes such as caused by adding hot water or ice which may lead to over shoot of the temperature. In this case the alarm would not sound. 
         [0015]    In at least one embodiment, a sous-vide circulator cooker has a turn-able or rotatable information display and control head. The control head can be configured to keep electronics housed therein away from steam and to enable easy viewing from different angles. 
         [0016]    In at least one embodiment, a sous-vide circulator cooker includes a detachable single or dual-section stainless steel skirt which allows for cleaning the skirt itself and cleaning of a heater and pump covered by the skirt. The provision of a stainless steel skirt can also act to ensure that no plastic components are directly wetted during use of the cooker. In at least one embodiment, the sous-vide circulator cooker&#39;s removable skirt also exposes the water pump impellers allow users to clean out food and debris in case of bag breakage. 
         [0017]    In at least embodiment a sous-vide circulator cooker includes a Wi-Fi/Blue tooth radio for recipe specification uploads from phone, tablet or PC and direct remote control and monitoring. Thus, in at least one embodiment of this disclosure a fluidic temperature controller can include a non-volatile memory that stores a plurality of recipe specifications and user generated data files as well as a control interface that enables a user of the sous-vide circulator cooker to select and recall recipe specifications. In at least one embodiment of this disclosure, a sous-vide circulator cooker can search for recipes that match certain specification criteria. 
         [0018]    In another embodiment, the system interface has dynamically color changing, icons, objects or background to notify an operator of system regarding temperatures and tank water levels. Additionally the controller may contain a speaker to sound music alarms and reminders. 
         [0019]    According to one aspect of this disclosure, a sous-vide circulator cooker can rotate the head controller. Storing most microelectronics within such a rotatable structure enables the microelectronics to be located away from the steam source. An interface on the head controller can also turn to enable a user to adjust a viewing angle.
