Microwave camellia seed -oil process application
First, the origin and quality of tea seed oil
Since the origin of the oil seed varieties and harvesting , drying in different forms, its moisture content , shelling percentage , oil content is also different. Therefore, the system operating parameters during oil there are also differences . The system features camellia seed oil tea seed oil contains high tea saponin , starch and sugar. In the press process, the starch in the pressing chamber as the expansion coefficient of the differences in the expansion coefficient of the protein , the pressing chamber pressure is only squeezed into the material by adjusting the impedance of the press and plasticity smoothly.
So, people shell containing virgin material consumption and water -oil is squeezed important operating parameters. Shell containing moisture content is too low or too high plasticity increases, pressure decreases ; otherwise the resistance is increased , squeezing hard , serious cause explosion bore squeeze machine , resulting in mechanical failure. Affect the leaching process is the key factor tea saponin , sugar and water . You Qiming water will produce large amounts of feed materials group ( commonly known as the oil eggs ) , could easily lead to leaching paths lengthened and material handling difficulties, severe will produce a lot of foam , so that the solvent does not come into contact with blanks , wet meal can not be distilled off . In the production process, the kernel shell containing tea seed oil should be based on the origin and species dependent.
Second, camellia seed oil pressing process
1 , the conventional hot pressing process
Camellia seed conventional hot pressing process: cleaning up an oil seed a magnetic one peel a kernel shell separation an billets ( broken ) a steaming and roasting ( quenched ) one press of a hot tea seed oil extraction of crude oil .
As can be seen from the process , hot pressing process and the general fuel no essential difference .
2, the conventional cold pressing process
Conventional tea seed oil cold pressed process: a clean-up an oil seed sheller a kernel shell magnetic separation a crush a cold tea seed oil extraction of crude oil .
Conventional cold pressed refers to raw materials in the clean , peel , kernel shells separated without heat treatment such as steaming and roasting direct pressing , squeeze the hair oil temperature is below 75 . Conventional cold-pressed oil prevents oxidation , so that virgin oils obtained better flavor , nutrients retained more completely .
3, the microwave-assisted cold pressing process
Microwave-assisted seed oil cold pressed process: cleaning up an oil seed a magnetic one peel a kernel shell separation an billets ( broken ) a microwave squeezing a tea seed oil hair oil. Microwave-assisted cold pressing process is a process based on conventional cold-pressed to increase the microwave tunnel , the crushed seed kernel oil uniform microwave irradiation , it has been initially damaged cells , easy to extract oil . As the material inside the tunnel in the microwave irradiation time is shorter , the material temperature is not higher than 55 ℃, benevolence cells still have to get through the crush damage . The process route in terms of oil quality upgrade from a step , but the output is still not very good overall efficiency .
4 , the temperature microwave-assisted pressing process
Medium temperature oil seed crushing microwave-assisted process: cleaning up an oil seed a magnetic one peel a kernel shell separation an billets ( broken ) a microwave irradiation
