Method for producing low-temperature cold-pressed and refined tea seed oil

The invention discloses a method for producing low-temperature cold-pressed and refined tea seed oil, and belongs to the technical field of deep processing of agricultural products. The method for producing the cold-pressed and refined tea seed oil comprises the following main processes of: performing low-temperature storage on screened tea seeds, cleaning, grading, shelling, separating, drying, crushing, pressing at a low temperature, filtering, degumming, decolorizing, deodorizing, winterizing, and packing finished refined oil. By the new technology of low-temperature cold pressing and refining, overheating and excessive chemical treatment of the oil in the conventional processing are avoided, meanwhile, the residue of harmful substances produced in the conventional high-temperature processing is effectively reduced at the same time, the production cost is remarkably reduced, the purely natural property of the oil is kept, and physiological active substances in the oil are kept as much as possible. The tea oil produced by the method is light in color, low in acid value and peroxide value, low in phosphorus content, fragrant and rich in nutrition, and has a long storage period; and a feasible new path is provided for deep processing and utilization of the tea seed oil.

The invention relates to a variable pressure distillation method for extracting pythoncidere and essential oil from Chamaecyparis plants. The pythoncidere is aqueous solution, and contains main effective ingredients including borneol, cedrol, carvacrol, bisabolol, and the like. The essential oil from Chamaecyparis plants is yellow and contains cedrene, thujopsene, cedrol, and the like. The variable pressure distillation process comprises the following steps: drying and pulverizing rhizomes of Chamaecyparis obtusa and Chamaecyparis formosensis, filling into a distillation tank, introducing steam from lower steam inlet of the distillation tank for 30-50 s, starting an oil pump to vacuumize so as to generate negative pressure of 40-60 kpa, reducing pressure and humidifying after pressure stabilizes, gradually restoring the negative pressure to normal atmospheric pressure after 20-30 min, connecting a coiled condenser for condensing vapor after 20-30 min, decolorizing with about 50-100 g activated carbon, separating oil phase and water phase, and filtering to remove impurities with filter screen to obtain the essential oil and hydrosol from Chamaecyparis plants, namely, water-soluble pythoncidere.

Ceramic polished brick and production method and production line of ceramic polished brick

The invention discloses a ceramic polished brick and a production method and a production line of the ceramic polished brick. The production line comprises a range-shaped texture forming set, a material block forming set, an atomization spraying system, a third material distributing device, a first roll pressing device, a cutting device, a gorge-shaped texture forming set, a sixth material distributing device, a second roll pressing device, a seventh material distributing device and a press device, all of which are sequentially connected through a belt. According to a preparing method, color attaching pulp is attached to a micro powder stack jointly formed by material blocks formed by a range-shaped texture material belt subjected to the action of a texture manufacturing device and tooth roller crushing, the poking operation and super-through line material filling procedures are carried out on pressed powder through two sets of different mechanical arm combinations, wherein the pressed powder is formed through material supplementing, prepressing and cutting and edge removing. The polished brick obtains the polished brick decoration texture jointly composed of the range-shaped texture, the lava-shaped texture and the gorge-shaped texture. The range-shaped texture is smooth and natural, the edge of the lava-shaped texture has color lines fine like silk yarn, the texture is infinitely close to the difference texture of natural stone, and the stone imitating effect is extremely good.

Method for extracting rose essential oil from fresh rose flowers

The invention discloses a method for extracting rose essential oil from fresh rose flowers, which relates to a method for spice extraction, in particular to a method for extracting rose essential oil from fresh rose flowers by using the organic solvent extraction and molecular distillation technology. The method comprises the following steps: carrying out lixiviation on fresh floribunda rose flowers by petroleum ethers, then sequentially carrying out filtration, dewaxing and concentration on the obtained product so as to obtain a first concentrated solution; carrying out lixiviation on the rose flower residues subjected to four times of lixiviation by an equivalent petroleum ether/dichloromethane mixed solvent, then sequentially carrying out filtration, dewaxing and concentration on the obtained product so as to obtain a second concentrated solution; mixing the first concentrated solution with the second concentrated solution, then adding the obtained mixture into a molecular distillation device so as to distill the mixture, thereby removing residual solvents, vegetable waxes, pigments and the like in absolute rose oil, and finally, obtaining the rose essential oil. The prepared rose essential oil is pure in aroma and clear in color and luster, the oil yield of the fresh rose flower reaches 0.1 percent, which is 3.3 times of the oil yield of the fresh rose flower through steam distillation.
