Mechanism for transforming rotating to reciprocating motion, or vice versa, comprising a first annular component (1) and a second annular component (3) coaxially located, the first beside the second, along a longitudinal axis (ΔA), wherein both are able to rotate around the longitudinal axis and to reciprocate along the longitudinal axis, wherein aide (A) of the first annular component (1) adjacent to the second annular component (3) is in continuous contact, in at least one point, with the neighbouring side (Γα) of the second annular component (3), such that the second annular component (3) is able to rotate relative to the first annular component (1) in continuous contact in at least one point with the adjacent side (A) of the first annular component (1), wherein the contacting sides are undulated surfaces (A, Γα), such that if the first annular component (1) and the second annular component (3) are forced into rotational motion relative to each other, remaining the same time in continuous contact, then every point of the undulated surfaces (A, Γα) will trace, relative to the other, an undulated trajectory and at the same will also execute, relative to the other, reciprocating motion.

In industrial processing, grains of rapeseed are dehulled. Cold-pressed rapeseed core oil is pressed from a low-hull grain fraction having at most 4 weight percent of hulls. In a press cake being generated, the cake temperature is limited to 70° C., and a first residual oil content is reduced to 8 to 28 weight percent of the dry matter. Pressurized steam is supplied, and the press cake is subsequently expanded to form collets. The steam is metered such that the press cake is temporarily heated to above 100° C. and the collets have a temperature of 80° C. to 95° C. after the expansion. The collets are extracted with an organic solvent, a second residual oil content being reduced to 2 weight percent or less of the dry matter. After the expansion, some of the collets are returned and mixed with the low-hull grain fraction in order to increase the friction when being pressed.

A process for a reactive separation of organic molecules from biomass includes a reaction step for the biomass, a simultaneous extraction step using a solvent, and a filtration step to recover products, wherein the products comprise ferulic acid and/or coumaric acid. The products are extracted from the biomass in a pressurized stirred batch reactor using a liquid extraction solvent and a base in which the ferulate and the coumarate remain.

A method designed to clarify the coffee oil contained in coffee grounds or in whole and/or damaged coffee beans. Said objective is achieved by way of a method that starts with inoculation of the coffee grounds or coffee beans with macromycetes, especially with white rot fungi, continuing with an incubation step that allows complete population of the coffee grounds or coffee beans by the fungal mycelium to be achieved, and finishing with steps of drying and extracting the coffee oil. The method disclosed allows colourless or pale yellow coffee oil to be produced, favouring the use thereof in cosmetic and food products, amongst others. International patent classification: Methods for preparing or isolating a composition containing fungal microorganisms (C12N 1/14) Technological sector: Chemical processes

Infused oil polishing systems and methods reduce or remove chlorophyll from bulk biomass saturated ethanol. A processing vessel includes a valved input port for receiving a biomass mixture and a valved output port for expelling a polished mixture containing the desired extract. The vessel is pressurized or evacuated, causing the chlorophyll-containing carbon to be trapped by the filter assembly as the desired extract mixture is discharged. The equipment operates at relatively low pressures of 40 psi or less, and one operator can run multiple units. The end user can control the degree of polishing by adjusting the amount of media used and resident time. The basic apparatus can also be modified to run in parallel or series combinations to increase throughput. An optional elevating rack provides for ease of cleaning, and no expensive ancillary equipment needs to be purchased.

Various aspects of the disclosure relate to methods and systems for extracting plant oil from plant material. A system may comprise a microwave emitter, an extraction chamber, and a cooling chamber. Microwave radiation emitted by the microwave emitter may dielectrically heat a microwave absorbing agent, which may heat the plant oil of the plant material. Plant oil of the plant material may be volatized in the extraction chamber and may be directed into the cooling chamber to be condensed.
