Claim:
1. An extraction reactor, for liquid extraction from granular material, comprising: at least one vertically extending flow pipe including a plurality of horizontally configured heat exchanger elements that fill a cross-section of the at least one vertically extending flow pipe completely or partially and that can be flowed through by the granular material and the extraction liquid, the plurality of heat exchanger elements subdividing the at least one vertically extending flow pipe into individual vertical compartments; at least one top-side inlet for the granular material; at least one base-side outlet for the granular material; at least one base-side supply for the extraction liquid; and at least one top-side outlet for the extraction liquid, wherein the plurality of heat exchanger elements are arranged to form groups of heat exchanger elements, by the heat exchanger elements for each group, connected successively in series, being flowed through, beginning with the vertically uppermost heat exchanger element of each group, by a medium for heat exchange.
