A FLUIDIZED fat composition is described which has an oil blend of 90-99.8 wt. % of an unhydrogenated liquid oil and 10-0.2 wt. % of a fully hydrogenated fat having an iodine value of less than 10 which forms a crystal network in the final composition. The composition optionally contains colors, flavorings, microcrystalline edible salt, essential oils, oleo and aqua resins, natural extractives in conjunction with herb and spices, cheeses and other seasonings, lecithin and antioxidants, starches,...

A method for obtaining an improved pack emplacement when packing a well with sand or gravel. A slurry of sand or gravel is pumped through the end of a tubing string that is extended to near the bottom of the interval to be packed; as the slurry is pumped, the tubing string is raised at a rate that is correlated with the pumping rate in order to maintain a fluidized bed of sand around the end of the tubing string as it moves through the interval to be packed.

Food particles are discharged onto a declining first section of an endless foraminous conveyor belt which carries the food particles through a freezing zone in which refrigerated air flows upwardly through the conveyor belt and the food particles. Gravity forces act on the food particles in the declining section, causing them to advance faster than the conveyor belt. This results in a thinning of the product bed in the declining section, making it easier to fluidize the food particles at the sta...

A fluidized bed furnace for consuming a liquid fuel in which there is a fluidization zone of increasing cross-sectional area adjacent to and downstream of the liquid fuel injection nozzles. This arrangement allows better dispersion of the oil and bed material giving more efficient combustion.

This invention relates to fluidized bed furnaces. There is an increasing interest in furnaces in which the fuel is burned in a bed that is maintained in a fluent condition by combustion air supplied to the bed, and a fluid to be heated is passed through heat exchange tubes disposed within the bed. Interest has so far centered on the use of water as the fluid but this presents problems, especially at start-up and shut-down when it can be particularly difficult to ensure that the heat exchange tub...

Fluidized bed apparatus includes a body having located therein a distributor provided with discharge ports connected to classifiers. Plates are located over the ports and air lances are disposed intermediate the plates and the ports. The plates serve to protect inbed tubing from erosion by entrained particles and the lances control the flow of material into the classifiers.

A circulating fluidized bed boiler including a furnace, a separator which is connected to the furnace to separate fluidized bed material from a flow leaving the furnace, as well as a return duct between the separator and the furnace to return the separated fluidized bed material into the furnace. The return duct includes a loop seal equipped with a heat exchanger and a supply of fluidizing medium and having an inlet and an outlet, which open into a chamber including the heat exchanger, i.e. a he...

A process is disclosed for discharging and transferring upwardly fluidized particles from a dense fluidizing layer forming section to a high-velocity transferring section having a diameter which is smaller than that of the dense fluidizing fluidized layer forming section, wherein at least one intermediate cylindrical section is provided between the dense fluidizing fluidized layer forming section and the high-velocity transferring section. The process can decrease the degree of changes in the am...

A fluidized bed apparatus has a rotary rotor 4 arranged at the bottom center thereof, a disintegrator mechanism 5 arranged above the rotary rotor 4, and a cylindrical draft tube 6 installed above the disintegrator mechanism 5. A fluidizing gas jetted from a gas dispersion plate 3 causes powder particles P in a processing container 1 to form a fluidized bed in which they circulate so as to ascend through the gap between the outer periphery of the rotary rotor 4 and the bottom inner wall of the pr...

A method for vaporizing organic materials onto a surface, to form a film includes providing a quantity of organic material in a fluidized powdered form; metering the powdered organic material and directing a stream of such fluidized powder onto a first member; heating the first member so that as the stream of fluidized powder is vaporized; collecting the vaporized organic material in a manifold; and providing a second member formed with at least one aperture in communication with the manifold th...
