摘要:
Device (V) for obtaining a wort (WO) from a mash (MA) in the beer brewing or beverage industry, at least comprising a receiving unit (AG) for receiving the mash (MA); at least one separating device (T; T1, T2) each having a surface (FA; FA1, FA2); wherein the surface (FA) has a multiplicity of openings (OP); wherein the device (V) is preferably suitable for separating the mash (MA) into the wort (WO) and a residual mash (RM) by means of the surface (FA) of the separating device (T); wherein the surface (FA; FA1, FA2) or a part thereof can be brought into contact with the mash (MA), if the mash (MA) is present in the receiving unit (AG) for separation into the wort (WO) and the residual mash (RM); and wherein, during the operation of the device (V), the surface (FA) is arranged such that it is moved or can be moved or can be rotated relative to the mash (MA), the residual mash (RM) and/or the receiving unit (AG).
摘要:
Processes for preparing extracts of natural products such as plant material, and for preparing purified extracts from crude extracts of natural products, by extraction with hot gas. Apparatus suitable for use in preparing extracts of natural products are also described.
摘要:
A method of treating a solvent in a wood processing operation is described. A first organic compound is extracted from an aqueous solution with a solvent. Then, the solvent is contacted with an alkali solution to remove a second organic compound from the solvent. For example, the first organic compound may be acetic acid and the second organic compound may be lignin. In another embodiment, a liquid-liquid extraction solvent used to extract acetic acid from an aqueous solution is rejuvenated by contacting the solvent with an alkali solution to remove a second organic compound from the solvent. The rejuvenated solvent is then recycled for further liquid-liquid extraction.

A hair growth promoting agent containing an effective ingredient extracted from malt is provided in accordance with the invention. It has also been discovered that malt is an effective hair growth promoting agent. A process for producing an extract of the effective ingredient and a device are also provided.
摘要:
In a process for separating miscible substances by mass transfer between two phases, at least one of which is a fluid phase (gas, vapor or liquid) and the other phase being a solid phase or a liquid phase (stationary or flowing in countercurrent with the aforesaid fluid phase, the mass transfer takes place and is substantially confined to the outside of the surface regions of the solid parts of porous material having the structure of an open pore foam, preferably substantially reticulated. This structure can be industrially reproduced in an idealized fashion in the form of interleading pores between which the solid parts are outlined in all three dimensions by concave shapes of spherical to near-spherical curvature corresponding to the outlines of densely packed phases.Column packings for chromotography, distillation, countercurrent extraction and similar process. The advantages are low pressure drops combined with high flow rates (which in the case of chromotography are advantageously in the turbulent range), low theoretical plate heights.
摘要:
Voluminous precipitates or suspensions are contacted countercurrently with liquid purification or extraction agents that hold the continuously supplied precipitate or suspension in the upwardly flowing liquid in a kind of fluidized bed. A suitable apparatus is also described.
