Abstract: Typical current methods for producing large quantities of extracts from solid raw materials such as ground, roasted coffee are designed for exhaustive extraction. Such methods are not ideally suited to producing high quality coffee extracts that are rich in flavor and fragrance, and which maintain the varietal characteristics of the roasted coffee from which they are produced. The current invention provides methods and apparatus for producing such high quality extracts. The invention provides methods that have sufficient flexibility and scalability to be used for a wide variety of applications, including for producing industrial-scale quantities of extracts for the food and beverage industry. The invention provides methods and apparatus that can produce highly concentrated, “gourmet quality” extracts for use as flavoring agents, beverage concentrates, and fragrances.

Such methods are not ideally suited to producing high quality coffee extracts that are rich in flavor and fragrance, and which maintain the varietal characteristics of the roasted coffee from which they are produced. The current invention provides methods and apparatus for producing such high quality extracts. The extracts produced according to the invention can be advantageously used for applications where high quality coffee extracts, with a relatively high concentration of soluble coffee solids and a relatively high level of sweetness but without substantial amounts of bitter oils and acids, are desired.

Abstract: A domestic barbecue grill is shown that has an exhaust manifold and smokestack in combination therewith that is operative to eliminate visible smoke particles and other combustible pollutants in the exhaust gasses that might otherwise flow freely from the smokestack. The device is operative to substantially burn up within the manifold all the visible smoke particles and other pollutants that flow from the cooking process taking place within the grill. The apparatus is operative to convert these emissions from the grill into invisible gaseous compounds before all of the exhaust gasses are discharged from the smokestack into the atmosphere.

Abstract: A smokestack addition to a conventional outdoor type of domestic grill is shown that provides a suction at the outlet from the cooking zone of the grill to pull the products of combustion arising from the operation of the grill which suction of the gasses is effective to minimize the circulation of carcinogens in such gasses from flowing over the food being cooked and directs the these effluent gasses over an afterburner associated with the stack that functions to initiate the oxidation of substantially all of the pollutants that flow away from the cooking zone and through the stack to be to be discharged into the atmosphere.

Abstract: This disclosure is concerned with a removable hood for use over the grill or broiler section of a counter top stove such as a Jen-Air.TM. stove having a suction exhaust inlet centered between the burners in the counter top.

Abstract: A wood burning combustion heater comprises a combustion chamber for long logs arranged to burn down from one end to the other in cigar-like fashion, an after-burner tube arrayed above and essentially parallel to the elongated logs with the air and burned gasses following an S-shaped path through the combustion chamber and out through the exhaust tube, an after-burner within said tube and a heat exchanger fed by the exhaust from said tube for heating air in indirect heat exchange and characterized further by an incoming air passage annulus surrounding the combustion chamber for pre-heating thereby; multiple levels of air admission for controlling combustion; electric ignition at the after-burner; bathing the exhaust tube, containing the after-burner, in flame through admission of secondary air to the region outside such tube; and high mass for even dissipation of heat.
