Title: Improvements in and relating to food frying apparatus
IPC: A47J27/08
Filed: 1965-07-09
Abstract: 1,120,842. Pressure cooking in fat. C. WAGNER. 9 July, 1965 [8 April, 1965], No. 29263/65. Heading A4D. A pressurized deep fat fryer includes a pot 18 to receive cooking fat, whose lower portion has a concavely curved wall 32 extending from a relatively narrow horizontal bottom wall 22 to a vertical side wall 25, and whose upper walls are stepped to form four different substantially rectangular cross-sectional areas, which increase in size from the bottom of the pot to the top. In operation cooking fat is supplied to the pot 18 and it is heated to the desired temperature by gas burners 48, which heat the upper portion of the curved wall 32, leaving a cold zone in the lower narrower portion of the pot. A wire basket containing the food is then placed inside the pot 18, a cover 68 is secured in pressure sealing relation to the top of the pot and a timer is set to the required length of cooking time. An exhaust vent 84 and a thermostat 96 control the pressure and temperature respectively. After the requried length of cooking time the timer energizes a solenoid 92 to open a valve 89, Fig. 1 (not shown) and release the pressure. Exhaust ducts 86 and 91 communicating with the interior of the pot 18 are disposed adjacent an exhaust flue 65 from the heating chamber to prevent freezing of moisture and congealing of fat in the ducts 86 and 91.

The boat is covered by a bell 23, supplied with the requisite inert atmosphere. The wire used may be produced by the process described in Specification 155,851. The process is stated to be applicable to the production of tungsten articles generally in which a large crystal structure is required. According to the Specification as open to inspection under Sect. 91 (3) (a), a coiled filament 28, Fig. 5 (Cancelled), is passed between electrodes 29, 30, between which short lengths of filament are heated and cooled before the succeeding length is treated.
