Embodiment 1

[0023] Embodiment 1: Refining cold-pressed tea seed oil

[0024] The cones of camellia oleifera are harvested, dried in the sun, the shell of the cones is manually removed, and the seeds of camellia oleifera are stored in a cold storage at 5°C for 25 days at low temperature. The impurity-removing and classifying machine removes impurities such as gravel and weeds in the camellia seeds, and obtains uniform-sized and pure camellia seeds without mildew. The shelling machine combined with the air sieve is used to shell the camellia seed and separate the shell and kernel, so that the shelling rate reaches 20%. Put 20kg of shelled camellia seeds into an oven at 60°C for drying, and after the camellia seeds are baked to a moisture content of 8%, they are taken out for pre-crushing treatment. The dried camellia seeds are crushed by a roller crusher, and the degree of crushing is controlled to 1 / 4 to 1 / 8 of the camellia seeds. Put the crushed camellia oleifera seeds into a low-temper...

Embodiment 2

[0026] The cones of camellia oleifera are harvested, dried in the sun, the shell of the cones is manually removed, and the camellia oleifera seeds are stored in a cold storage at 10°C for 20 days at low temperature. The impurity-removing and classifying machine removes impurities such as gravel and weeds in the camellia seeds, and obtains uniform-sized and pure camellia seeds without mildew. The shelling machine combined with air sieve is used to shell the camellia seed and separate the shell and kernel, so that the shelling rate can reach 10%. Put 50kg of shelled camellia seeds into an oven at 60°C for drying, and after the camellia seeds are baked to a moisture content of 8%, they are taken out for pre-crushing. The dried camellia seeds are crushed by a roller crusher, and the degree of crushing is controlled to 1 / 4 to 1 / 8 of the camellia seeds. Put the crushed camellia oleifera seeds into a low-temperature press, set the pressing temperature as 70°C, the rotating speed as ...

Embodiment 3

[0028] The cones of camellia oleifera are harvested, dried in the sun, the shell of the cones is manually removed, and the seeds of camellia oleifera are stored in a cold storage at 5°C for 25 days at low temperature. The impurity-removing and classifying machine removes impurities such as gravel and weeds in the camellia seeds, and obtains uniform-sized and pure camellia seeds without mildew. The shelling machine combined with the air sieve is used to shell the camellia seed and separate the shell and kernel, so that the shelling rate reaches 20%. Put 30kg of shelled camellia seeds into an oven at 80°C for drying, and after the camellia seeds are baked to a moisture content of 8%, they are taken out for pre-crushing treatment. The dried camellia seeds are crushed by a roller crusher, and the degree of crushing is controlled to 1 / 4 to 1 / 8 of the camellia seeds. Put the crushed camellia oleifera seeds into a low-temperature press, set the pressing temperature as 75° C., rotate...

Abstract

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.

Description

1. Technical field [0001] The application relates to a production method of low-temperature cold-pressed refined tea seed oil, which belongs to the technical field of deep processing of agricultural products, and specifically relates to low-temperature cold-pressed oil seed oil technology and refining technology. 2. Background technology [0002] Camellia oleifera originated in China. It is the main woody edible oil tree species unique to southern my country and one of the four largest woody edible oil tree species in the world. The area of ​​Camellia oleifera forests in my country accounts for more than 80% of the woody edible oil plant area. The oil obtained from Camellia oleifera seeds is tea oil, the fatty acid composition of tea oil is similar to that of high-grade edible oil-olive oil, its unsaturated fatty acid content exceeds 80%, and has high nutritional value; no chemical fertilizers and pesticides are applied during the cultivation of camellia oleifera , so camell...
