Problems solved by technology

[0004] At present, the main problems in the production of high-quality tea seed oil in my country are: the tea seed oil produced by hot pressing method is easy to lose the natural nutrients, active substances and inherent fragrance in the tea seed oil, and the color of the tea seed oil obtained is dark, so it must be processed Further refining process consumes a lot of energy
The production of tea seed oil by low-temperature pressing method is difficult for shelling and separation of shell and kernel. After shelling, the oil content of tea seed kernel is high, it is difficult to pressurize, and it is easy to knot the chamber. Ordinary oil presses cannot operate normally.
There are problems such as high energy consumption and unstable oil quality in the refining process
There are various sources of tea seeds, and there are great differences in oil composition and active components. Standardized production technology needs to be established urgently

Embodiment Construction

[0025] Take the production of 100kg tea seed oil as an example.

[0026] (1) Dry the collected Camellia oleifera cones naturally, break the shell, take out the camellia oleifera seeds and dry them in the sun, store them in a low temperature environment of 0-5°C for a period of time, let them ripen naturally, and then clean the moldy tea seeds, moisture Content 7%-10%;

[0027] (2) take by weighing 600kg the tea seed after screening, carry out dehulling and separation by the tea seed peeling and separating machine, require husk content 10% in the seed kernel;

[0028] (3) Put the separated tea seed kernels into a twin-screw oil press, press the oil at a low temperature between -10°C and 40°C, and control the temperature of the cake outlet at 40°C to 60°C to achieve normal temperature oil pressing , to obtain cold-pressed crude oil, screw speed 35-40r / min, feed rate 80-100kg / h;

[0029] Crude oil filtration: The crude oil is filtered twice with a closed filter and a bag filter...

Abstract

The invention provides a method for preparing tea seed oil in a low-temperature cold pressing manner. The method comprises the following steps of cleaning tea seeds, removing shells and separating, milling oil at normal temperature, washing in water at low temperature, dehydrating under negative pressure, refining at low temperature, filtering for many times, winterizing and dewaxing. The method for preparing the tea seed oil in the low-temperature cold pressing manner, provided by the invention, has the advantages of simple process, low energy consumption and high oil yield; and the prepared tea seed oil has shallow color, high quality and comprehensive nutrition, and also keeps the original flavor of tea oil.

Description

technical field [0001] The invention belongs to the field of oil processing, in particular to a method for preparing tea seed oil by low-temperature cold pressing. Background technique [0002] In 2009, the Ministry of Health approved tea seed oil as a new resource food. However, due to a series of technical bottlenecks in the production of high-quality tea seed oil, this resource advantage has not been truly transformed into an economic advantage. It has become an urgent need for the development of the oil industry to study and solve the key technical problems in the production of high-quality camellia oil. [0003] The unsaturated fatty acid content of tea seed oil is higher than that of olive oil, reaching more than 83%. The content of vitamin E is very high, especially rich in tea polyphenols. It is an edible oil with extremely rich nutritional value and is known as "the top nutritional oil in the East". . [0004] At present, the main problems in the production of hi...
