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 improved baffle assembly for heat exchanger tubes comprising a shaft and at least one opposing pair of expanding baffles positioned coaxially on the shaft, each expanding baffle comprising a central hub portion and a plurality of extension portions each radiating outward from the hub portion at complementary oblique angles so that the central hub portions of each baffle are spaced apart along the shaft and the distal ends of the extension portions of each baffle are brought into physical contact.

Use of the pressure assist system allows for optimal cooking of batches of food of many sizes.

A transfer conveyor for food process lines is equipped with hardware to enable pivoting in place and other hardware to enable and reversible expansion and contraction of the transfer conveyor, or at least the upper, food-product carrying run of the endless conveyor belt therefor.

Systems are disclosed for cleaning a fryer using a washing element coupled to a bottom wall of a cooking chamber. An upper portion of the washing element extends above the bottom wall of the cooking chamber and includes a plurality of spray jet nozzles that are separated at predetermined angles relative to one another around a periphery of the upper portion of the washing element to orient the plurality of spray jet nozzles so as to spray a plurality of pressurized streams of the cooking medium to predetermined areas of the cooking chamber, including at least one corner of the cooking chamber. Also disclosed is a fryer that includes a spreader bar that maintains an electric heating coil in the serpentine pattern. The spreader bar is coupled to the upper surface of the electric heating coil and is disposed at a predetermined distance away from the bottom wall.

A fryer and method for cooking food products is provided that automates the movement of baskets carrying the food products. The fryer includes a cooking chamber with a heating element located therein for heating cooking medium in the cooking chamber. The fryer also includes at least one vertical transport assembly that selectively engages with and moves the basket vertically into and out of the cooking medium. A horizontal transport assembly selectively engages with and moves the basket horizontally between different positions. The horizontal transport assembly hands off the basket to and from the vertical transport assembly, and first and second hooks on the horizontal transport assembly engage with front and rear receiving mechanisms on the basket to continuously maintain at least two points of contact with the basket. This allows for controlled pivotal movements of the basket when food products are to be added or removed from the basket.

A continuous fryer that includes a vessel (kettle) (11) through which oil (13) flows in a predetermined direction (12). An upstream end of the kettle (11) is a flow control device (34) that at least aids in maintaining linear flow through the vessel (11) is said predetermined direction (12).

A ceramic deep-frying device capable of withstanding high temperatures and releasing far-infrared energy is made by grinding and mixing mullite, spodumene, energy ceramic material, ball clay, and kaolin clay into clay blank; molding the blank into ceramic green body; and sintering the green body at 1250-1320 C. for 18-24 hours. The device is completely immersed in the oil in a deep-frying vessel while leaving a gap between the device and heating pipe in the vessel or the inner bottom wall of the vessel, for enabling the oil to circulate through the through holes in the device due to temperature difference in the oil, causing the energy ceramic material to release anions and far-infrared rays that decrease van der Waals forces between oil molecules, and hence split, the oil molecules, thereby extending the service life of the oil, shortening the deep-frying time required, and lowering the oil content of deep-fried food.

An electric cooking appliance includes a base, a ventilation system arranged to create an airflow, a heating system arranged to heat the airflow, and a removable cooking basket. The appliance also includes a removable housing accommodating the ventilation system and the heating system, the housing being designed to be arranged on the base in order to cook the food arranged in the cooking basket carried by the base, a removable container designed to receive a cooking bath, another removable housing from which there extends a heating element, the other housing being designed to be arranged on the base in order to cook the food arranged in the container.

A fryer system and method for producing fried food pieces are disclosed herein. A fryer, located in a frying region of the fryer system, produces fried food pieces. An adjustable draining device, located in a draining region of the fryer system, is downstream from the frying region and controls a residence time of the fried food pieces in the draining region. A set of takeout conveyors bridges the frying region and the draining region and reduces a bed depth of the fried food pieces as the set of takeout conveyors transfers the fried food pieces from the fryer to the draining device. An enclosure at least partially encloses the frying region and the draining region to maintain a controlled environment within the draining region.
