Methods for adjusting the pressure in a cooking chamber of a pressure fryer are provided. The pressure inside the cooking chamber is determined in response to detecting closure of a valve that vents the cooking chamber. The pressure in the chamber is compared to a predetermined pressure. If the pressure in the chamber is less than the predetermined pressure, a pressure assist system is activated. The pressure assist system includes an air pump and/or pressure source, and when activated, supplies a gas to the cooking chamber to increase the pressure in the cooking chamber. The pressure may be determined at a predetermined time after closure of the valve, and an amount of gas to be added to the cooking chamber determined based on a difference between the measured pressure and the predetermined pressure.

An automatic cooking medium level control system for a cooking apparatus, e.g., a fryer, may include a cooking vessel having a first temperature sensor at a first level of the cooking vessel and a second temperature sensor at a second level of the cooking vessel. A reservoir holding a cooking medium, such as cooking oil, may be in fluid communication with the cooking vessel. A controller may monitor temperature data from the first and second temperature sensors to determine whether the level of cooking oil in the cooking vessel has lowered. Upon determining that the cooking oil level has lowered, the controller may actuate a supply mechanism, such as a pump, which may be disposed on a fluid communication path between the reservoir and cooking vessel, which may enable the introduction of cooking medium from the reservoir to the to the cooking vessel.

Automatic cooking medium level control systems and methods

Methods and systems disclosed herein may be methods for rapidly increasing pressure in a pressure fryer cooking vessel during a cooking cycle. Such methods and systems may comprise determining whether a pressure output in the cooking vessel is closed. Such methods and system may also include determining a pressure of the cooking vessel, comparing the pressure of the cooking vessel to a predetermined optimal pressure to determine whether the pressure of the cooking vessel is less than the optimal pressure, and activating a filter pump configured to supply air from a drain pan into the cooking vessel in response to determining that the pressure output is closed and the pressure of the cooking vessel is less than the optimal pressure. Such methods and systems may further include deactivating the filter pump when the pressure within the cooking vessel is equal to or greater than the optimal pressure.

A system for delivering a cooking medium of a cooking apparatus includes a cooking medium tank for storing the cooking medium and a rotary valve including a rotary inlet configured to be in fluid communication with the cooking medium tank. The rotary outlet further includes a plurality of rotary outlets including a first rotary outlet in fluid communication with a first cooking vessel and a second rotary outlet in fluid communication with a second cooking vessel. Moreover, the rotary valve is configured to selectively place the rotary inlet in fluid communication with one of the plurality of rotary outlets. In other embodiments, the system further includes a motor operatively connected to the rotary valve and configured to operate the rotary valve to select one of the plurality of rotary outlets.

A fryer apparatus includes a cooking chamber, at least one heating element in the cooking chamber, a filter pan that filters cooking medium from the cooking chamber, a drain valve that controls flow of cooking medium from the cooking chamber, and a filter pump that pumps filtered cooking medium from the filter pan to the cooking chamber. Inlet orifices are disposed in the cooking chamber, and selectively eject filtered cooking medium into the cooking chamber. A controller controls the drain valve to adjust the rate of flow from the cooking chamber, and selectively activates at least inlet orifice of the plurality of inlet orifices to eject filtered cooking medium into the cooking chamber. The controller is configured to control the drain valve and the selective activation of the at least one inlet orifice to maintain a substantially constant level of cooking medium in the cooking chamber throughout a filtering operation.

A cooking apparatus includes a cooking chamber for receiving a. cooking medium, a lid configured to cover the cooking chamber, and a lid locking system. The lid locking system includes a pressure lock pin coupled to a movable diaphragm, an electronic lock pin coupled to the lid, and a latch. The latch includes a pressure lock pin aperture formed therein to accommodate the pressure lock pin, and an electronic lock pin aperture formed therein to accommodate the electronic lock pin. The pressure lock pin engages the latch in response to pressure in the cooking chamber exceeding a predetermined threshold, and the electronic lock pin engages the latch in response to a lock signal from a controller.

A cooking apparatus includes a first and second cooking vessel, a drain manifold connecting the first and second cooking vessel to a drain container for storing cooking medium, a first drain valve and second drain valve configured to connect the first and second cooking vessel with the drain container. A first drain lever selectively opens and closes the first drain valve, and a second drain lever selectively opens and closes the second drain valve. A first and second drain lever indicator indicate an operational status of the first and second drain valves, respectively. A controller monitors the first and second drain valve. When the first drain valve is open, the second drain lever indicator indicates a warning when the second drain lever is operated. When the second drain valve is open, the first drain lever indicator indicates a warning when the first drain lever is operated.

A fluid fill system includes at least one sensor for indicating whether a fluid level in a reservoir is equal to or greater than a predetermined fluid level and a process control. The process control obtains a reading from the at least one sensor at a predetermined interval and increments a counter if the reading indicates that the fluid level is equal to or greater than the predetermined fluid level and decrements the counter if the reading indicates that the fluid level is less than the predetermined fluid level. Process control operates a fluid supply mechanism when a value of the counter moves beyond a predetermined value.

A control system for controlling the heating of a product in a dielectric oven comprises at least one dielectric heating circuit including an electromagnetic energy source, such as a triode vacuum tube, having an anode and a resonant circuit including at least one inductor and at least a pair of capacitors. Each capacitor includes two capacitor plates and one of these capacitor plates is moveable, such that each pair of capacitors forms a variable capacitor in which the product to be heated is a dielectric.

A motor is used to increase or decrease a distance between the plates of at least one of said capacitors, thereby adjusting the electromagnetic energy delivered to the product. A processor receives ammeter measurements, whereby the distance between the pair of capacitor plates is adjusted to increase or decrease the actual anode current. The processor also receives, stores, and retrieves a requested anode current and compares the requested anode current to the actual anode current to determine whether to increase or decrease the distance between the pair of capacitor plates. Alternatively, the electromagnetic energy source may have a duty cycle adjusted by a keying circuit or an anode voltage adjusted by a voltage control device, or both. The processor may include a timer, whereby an average actual anode current is measured. The processor may receive, store, and retrieve a requested average anode current and compares this current to the actual average anode current to adjust the electromagnetic field electrically by either increasing or decreasing the duty cycle or increasing or decreasing the anode voltage of the electromagnetic energy source, or both, and thereby increase or decrease the average actual anode current.
