Abstract

A process for producing instant coffee, which is dissolved in powder form by extracting coffee. Bake the crushed into sections in cells for permeability to produce extraction fluid. The first type from the atmospheric extraction phase (1) and the second extraction liquid from the pressure stage (2), then evaporated that first type of extraction fluid to reach a dry matter concentration of more than 35% by weight and evaporate the extraction fluid of the type that was 2 until the dry matter concentration is lower than 25% by weight, then mix the two extraction liquids to condense the vapor from the evaporation of the The first liquid extraction and concentrate And the concentrated substance that was obtained through the process For changing the mixture into coffee powder, which is dissolved again Application to instant coffee powder production by segmental extraction

Claims (8)

1. Process for producing instant coffee, dissolving in powder form containing Ground roasted coffee is used for separate extraction in an extraction system with atmospheric extraction area. And the extraction area using pressure The first extracts are obtained from the atmospheric extraction area and the second extracts from the pressure extraction areas; Evaporate the first set of extracts until concentrated, resulting in a concentrated first set of extracts with a More than 35% dry matter by weight, and the vapors are condensed and concentrated to get Fragrant concentrates Evaporate the second extracts until concentrated. To increase the dry matter concentration of things Second batch to content below 25% by weight, a second set of concentrations; Mix first and second concentrations together to get extract mixture. Evaporate the extract mixture until concentrated to get a concentrated, concentrated extract mixture. Of more than 40% dry matter by weight; Add the concentrated scent to the concentrated extract mixture; And change the concentrated extracts that add fragrance into powder form 2.Process for producing instant coffee, dissolving as a result containing The ground coffee is extracted separately in an extraction system with atmospheric extraction areas. And the extraction area using pressure The first set of extracts will be obtained from the atmospheric extraction area. And extraction set The second from the pressure extraction area; Evaporate the first set of extracts until concentrated so that the first batch of extracts is concentrated with the Substances that are more than 35% by weight and condensation and concentration are obtained. Fragrant concentrates To concentrate the second set of extracts to increase the dry matter concentration of the extracts. The second batch until the volume is below 25% by weight, the second concentrate is obtained; Mix the first and second concentrate extracts together to get extract mixes. Evaporate the extract mixture until concentrated to get a concentrated, concentrated extract mixture. Of more than 40% dry matter by weight; Convert the concentrated extract mixture into a powder form; And add concentrated substances that have fragrance in the powder 3. Process according to claim 1 or 2, which concentrated the second set of extracts until the dry matter content was from 15% to approximately under 254% by weight. 4. Process according to claim 1 or 2, which brings the first and second extracts to Dry matter concentration during mixing In which the extracted mixture had a dry concentration of more than 30% by weight 5. Process according to claim 1 or 2 which also includes Before concentrating the first batch of extracts, the first batch of extracts are extracted with water vapor, condensed the evaporators. From the first set of extracts, condensed volatiles are obtained. And volatile mixtures that are condensed and Mix the concentrate before changing the concentrate mixture into a powder form. 6. Process according to claim 5, which also consists of heating the extracts. First before evaporation 7. Process according to claim 1, which also consists of the introduction of concentrated substances containing odor Fragrant come in contact with the oil to hold the aroma of the concentrate with the oil, then spray the scented oil. The oil is fixed on the powder. 8. Process according to claim 2, which also consists of the introduction of concentrated substances containing odor Aroma Come in contact with the oil to hold the scent of the concentrate with the oil from the scented oil spray. The oil is fixed on the powder.
