Patent DE-4028112-A1 (DE)
Title: Reducing emission from cooling of coffee beans - comprises sepg. first cooling phase from subsequent phases and air from first phase is used e.g. gas combustion air in coffee roaster
Inventor: ROEBEN KLAUS WILHELM PROF DR I
IPC: A23F5/04
Filed: 1990-09-05
Abstract: In a procedure for controlling the emissions from the cooling of roasted coffee beans or similar prods., the exhaust air from the 1st cooling phase is cleaned separately from the exhaust air from later cooling phases. If initial cooling with water is not used, the first cooling phase consists of reducing the temp. from about 200-300 deg. C to 60-90 deg. C. If initial water cooling is included, the 1st cooling phase starts at about 100-150 deg. C. The air from the 1st cooling phase may be used as combustion air in the coffee roaster, or as auxiliary air in the roasting chamber, or may be treated together with the exhaust air from the initial water cooling procedure. The cooling circuit of the first phase is sepd. from those of subsequent phases. USE/ADVANTAGE - In the cooling of roasted coffee beans and similar prods.. The cost of cleaning and deodorising the exhaust air is dramatically reduced.

Patent DE-4123112-A1 (DE)
Inventor: RIENECKER REIMUND
IPC: B01D29/35
Filed: 1991-07-12
Abstract: The invention relates to a pressure sorter having a casing which is cylindrical or circular in sections perpendicular to the central axis of the same, which is provided with at least one inlet opening and outlet opening each and a certain pressure drop between them, a rotationally symmetric screen basket having, centrally arranged within the same, a rotor and matter sorting space and radially outside the screen basket, located between this and the casing, a material space. The invention is characterised in that the cross section of the material space, in sections parallel to the central screen basket axis, is matched to the particular mass throughflow in such a manner that the static pressure drop in the material space produced as a result of the flow velocity is always small enough so that the flow velocity through the screen openings of the screen basket, resulting from the pressure difference between matter sorting space and material space, is at most 2.5 m/s at each point and the deviation to higher values (upwards) from an arithmetic mean value purely theoretically based on the total surface area of the screen through-holes is at most 25 % of this value over the entire screen basket periphery.

Inventor: BAUER HEINZ DIPL PHYS
IPC: F25J3/02
Filed: 1991-08-19
Abstract: Described is a method of separating higher-boiling hydrocarbons from a gas mixture containing these hydrocarbons plus lower-boiling compounds by fractional distillation. The gas mixture (6) is partially condensed (7) and passed into a separation column (9). A fraction (27) rich in higher-boiling hydrocarbons is drawn off at the bottom of the column (9) and a fraction (10) rich in lower-boiling compounds is drawn off at the head of the column. The head fraction (10) is partially condensed (11). The condensate thus formed is returned to the separation column (9). Both the partial condensation of the gas mixture and that of the head fraction are produced by indirect heat exchange (7, 11) with a refrigerant which is made up of several components and is circulated in an external circuit (18).

Patent DE-4221807-A1 (DE)
Inventor: SCHAEFER RAINER DR
IPC: G01N21/27
Filed: 1992-07-03
Abstract: Process for the analytical determination of the concentration of a component of a medical specimen, in which a reaction of the specimen with reagents leads to a time-dependent change S(t) in a measurand (measured value) S, and the concentration C is correlated in accordance with an evaluation curve C-(X) with an input variable X derived from S(t). The evaluation curve is multi-valent at least for some of the possible X-values. In order to assign an input variable X to one of the subregions and thereby to achieve a unique correlation with a specific concentration C, the following steps are carried out:   - During a training run, a discrimination algorithm is carried out at least once, in which measurements of S(t) are used to generate a discriminator set and from this a score is respectively calculated using a method of multivariate statistics, and it is checked whether the scores can be divided into separate subsets in which the concentrations are correctly assigned to the subregions of the calibration curve. The discrimination algorithm is repeated using different discriminator sets, generated from the measurements of S(t) in accordance with different generating methods, in order to establish an operative discrimination algorithm. - Measurements of S(t) are used in an analysis run to calculate in accordance with the operative discrimination algorithm an analysis score which is compared with the pivoting score, and the measurement result is assigned to one of the component curves of the calibration curve by comparison of the analysis score with the pivoting score.
