Problems solved by technology

At the same time, tea seed kernels contain more colloidal substances. Under high temperature and high humidity, they are easy to stick together and become hard lumps after cooling, which brings great difficulties to the production and processing of tea oil.
When currently processing and pressing tea oil, the pressing temperature is about 105°C, and the water content of the material is above 7-8%, resulting in a low oil yield, generally around 10%. After repeated tests, a method to increase the oil yield has been obtained

Embodiment Construction

[0005] A kind of extracting method of improving tea seed oil yield described in the present invention, at first dry tea seed is screened, winnowing removes various impurity, and then carries out the shelling treatment of tea seed, makes material shell rate be controlled at 3- Within the range of 5%, the moisture content of the shelled material is about 16%. Then use a vibrating fluidized bed or other drying equipment to dry the material. The drying temperature is controlled in the range of 70-75°C, so that the moisture content of the dried material reaches 3-4%, and then add 5% of the weight of the material. The pieces of rice bran are mixed well and put into the press, which can increase the oil yield of tea seeds by 3-4 percentage points compared with the original high temperature and high water content material, and the tea oil can be squeezed to achieve the best effect. The extracted camellia oil is coarsely filtered and degummed by adding hot water at 50-60°C; deodorized ...

Abstract

The invention relates to an extraction method for improving the oil yield of tea seeds. The tea seeds are subjected to the treatment of screening, winnowing, impurity removal and shelling; and the material is dried at a temperature between 70 and 75 DEG C so that the water content of the material reaches between 3 and 4 percent; and 5 percent of bran coat is added into the material and is extracted. The method can overcome the disadvantages that tea seeds are vulnerable to adhesion and agglomeration, so as to form hard lumps and produce caramelization due to high content of tea saponine, and can increase oil yield by 3 to 4 percentage points.

Description

1. Technical field [0001] The invention relates to extracting tea seed oil by a physical method, in particular to an extracting method for improving the oil yield of tea seeds. 2. Background technology [0002] Tea seed kernels contain about 9% saponin and 10-18% oil. Saponin is hygroscopic and easily soluble in hot water. Under high temperature and high humidity conditions, the hydrogen and oxygen (HO) of saponin can easily Broken into aglycone or secondary glycosides and polysaccharides, it is easy to produce caramelization. At the same time, tea seed kernels contain more colloidal substances. Under high temperature and high humidity, they are easy to stick together and become hard lumps after cooling, which brings great difficulties to the production and processing of tea oil. When currently processing and pressing tea oil, the pressing temperature is about 105°C, and the water content of the material is above 7-8%, resulting in a low oil yield, generally around 10%. Aft...
