Patent ID: 8495954

Claim:
Equipment for roasting edible seeds comprising: a housing containing: a drum receiving a product to be roasted, the drum having at least one feed opening for introducing the product, and at least one discharge opening for unloading the product after the roasting, the drum being in a fixed position; an air suction fan conveying an air flow into the drum; at least one delivery duct fluidly conveying the air flow from the air suction fan to the drum, the delivery duct comprising a U-shaped portion having a first section with at least one resistance or heater to heat the air flow before introduction into the drum, and a second section having partitions arranged cross-wise to the air flow to reduce speed of the air flow and optimize heat exchange efficiency with discharged air; and at least one device housed within the drum to move the product, the at least one device comprising at least one rotary shaft having one or more substantially radial arms or blades stirring the product during the roasting, wherein the drum is substantially cylindrical in shape and has a longitudinal axis, and wherein the drum has at least one inlet hole for the introduction of the air flow, the at least one inlet hole being provided in a lateral position on a surface of the drum, and further has one or more outlet holes for an outflow of the air flow, the one or more outlet holes being provided on the surface of the drum in a lateral position opposite to the at least one inlet hole and/or on a lower lateral portion of the surface of the drum, such that the air flow flows into the drum in a direction substantially orthogonal to the longitudinal axis and further flows out of the drum in a direction that is substantially perpendicular to the longitudinal axis and/or that is oriented downward.
