摘要:
The present invention relates to two novel crystal forms of a known compound, 1-[5-Methanesulfonamidoindolyl-2-carbonyl]-4-[3-(1-methylethylamino)-2-pyridinyl] piperazine monomethanesulfonate salt, which are useful for treating humans who are HIV positive, which are identified by a powder X-ray diffraction spectrum known commonly as the “S” and “T” forms.
摘要:
A combination microwave and air impingement oven has two magnetrons and an air handling system that includes two or more reciprocating ducts through which air is dispensed into the oven. The rotating ducts are configured to stir microwave energy in the oven to prevent formation of hot spots and to sweep microwave radiation over the surface of the food product. A foraminous partition, configured to encircle a portion of the cooking chamber, has a central portion and extremities mounted to divide the interior of the cabinet into a cooking chamber and an air heating chamber. The partition extends around a major part of the periphery of the cooking chamber such that air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.
摘要:
A method and apparatus for vending a hot food product wherein a sealed container is moved from a protective sleeve and deposited in an oven where heat is transferred to the container for initially melting a protective sealing film and then heating the food product. After the food product has been heated, the container is removed from the oven and reinserted into the protective sleeve prior to dispensing the heated food product.
摘要:
A method and apparatus for heating a product which includes a plurality of tapered ducts in a cabinet above and below a conveyor to form streams which are directed toward the product. Spent air is drawn through return ducts which have intake openings centered between entrance and exit openings in the cabinet and centered between lateral edges of a conveyor and between the tapered ducts to provide a balanced flow of spent air in the cabinet to the return opening. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a conveyor extends to cause most of the heated air to be drawn to the return duct opening and to maintain internal pressure in the cabinet to prevent ingress and egress of air through the opening.
摘要:
A method and apparatus for maintaining a food product at or above a desired serving temperature wherein a volume of dehumidifier material, such as calcium sulfate, is heated to a temperature greater than the predetermined serving temperature of the food product and positioned in heat exchange relation with the food product, such that heat is transferred from the heated dehumidifier material to the food product and moisture is transferred from the food product to the dehumidifier material.
摘要:
Apparatus for transferring heat between temperature controlled air dispensed from a pair of oscillating ducts and a food product in a cabinet having an interior compartment bounded by front, side and rear walls. A foraminous partition, having a central portion and extremities, is mounted to divide the interior of the cabinet into a cooking chamber and an air conditioning chamber. It is configured to encircle a portion of the cooking chamber such that the air conditioning chamber extends around a major part of the periphery of the cooking chamber wherein air is drawn along multiple paths toward side walls and toward the rear wall from the cooking chamber.
摘要:
A method and apparatus for heating or cooling a product which includes a plurality of tapered ducts in cabinet above and below a turntable to form streams which are directed toward the product. Spent air is drawn through intake openings in return ducts in the cabinet. Temperature controlled gas is delivered at an angle through an array of openings adjacent opposite edges of an opening through which a product is loaded on the turntable in a loading zone to cause most of the heated air to be drawn to return duct openings and to maintain internal pressure in the baking zone in the cabinet to prevent ingress and egress of air through the loading opening. Orifices are formed in a circular array of rings such that the sum of the areas of orifices in each ring spaced from the axis about which the turntable rotates is substantially equal.
摘要:
The invention is an apparatus and method for measuring the heat transfer and the rate of heat transfer in thermal exchange processes such as food processing, thermosetting of plastics, and freezing processes. The apparatus comprises a target module and a data recording module. The target module comprises a target having a known mass and known thermal characteristics. The black body edge effects of the target are minimized by an edge shield positioned adjacent to the target. The edge shield is physically separated from the target so that conductive heat transfer between the two elements is minimized. The edge shield supports the target such that at least one surface of the target is exposed to the surrounding environment. A temperature sensor measures the change in temperature of the target. The data recording module may be insulated so that the calorimetric data may be recorded in extreme temperature environments.

摘要:
Apparatus for thermally treating food products by impingement heating or cooling, comprising a plenum having a plurality of inwardly inclined front wall panels adapted to direct the flow of a temperature-controlled gas through at least one elongated plenum outlet port in fluid communication with a duct assembly comprising an elongated manifold coextensive with the elongated plenum outlet port and providing substantially unobstructed fluid communication between the elongated plenum outlet port and a plurality of tapered ducts having at least two inwardly inclined walls, including at least one inwardly inclined side wall.
