How to extract oil from camellia seeds? | Camellia seed oil production process

Camellia oil processing needs to go through cleaning, shelling, crushing,cooking, pressing, refining and other processing steps from raw materials to finished camellia seed oil.

Here are the description of the specific process steps:

Step 1: Material selection and cleaning

High-quality oil is the basis for squeezing healthy camellia oil. Material selection is also a big deal. In the process of material selection, we try to choose camellia seeds with full particles, no dry stir-frying, crushing, and mold. Such camellia seeds will have better oil production effect and will eventually greatly improve the quality of oil. Then the camellia seeds are cleaned and de-stoned to remove impurities such as stones, stems and mud blocks, keep the oil stems, and improve the squeezing efficiency.

Step 2: Shelling and crushing

The next step is to shell the camellia seeds. There is a shell on the surface of the camellia seeds, and professional shelling machine equipment is needed for shelling. Shelling is for subsequent processes, steaming and heating are more uniform, and pressing is smoother. After shelling, a crusher is used to crush it. The surface area of ​​the crushed tea seeds is increased, which is conducive to the transfer of temperature and moisture during softening.

Step 3: Cooking

The symbol of hot pressing process, camellia seeds are steamed and fried to control the temperature and moisture of oil. The purpose of steaming and frying is to make the oil condense, create conditions for accelerating the oil yield, adjust the organizational structure of the billet, and make the plasticity and elasticity of the billet meet the requirements of pressing with the help of moisture and temperature, and the pressed camellia oil tastes more mellow.

Step 4: Pressing

The camellia seed oil after the above pretreatment enters the oil press to press out the oil. The advanced level of the oil press equipment and the camellia oil pretreatment process affect the oil output effect and pressing efficiency. The camellia seed oil obtained at this time is not a finished oil, and it is necessary to remove impurities in the oil through refining process.

Step 5: Refining

The camellia seed crude oil will contain impurities such as phospholipids, free fatty acids, pigments, and moisture. The presence of these impurities will affect the quality of edible oil, causing the edible oil to easily become rancid and deteriorate, and long-term use may affect human health. Therefore, the crude oil needs to be refined to remove impurities in the oil, as well as chemical components that are harmful to the human body due to high temperature. camellia seed oil can improve the quality of oil after being processed by refining equipment, which can improve the quality of oil, change the transparency and color of oil, and increase the safety of consumption. It is an essential equipment for creating high-quality oil.

Step 6, dewaxing

The camellia seed oil dewaxing process is based on the melting point difference between wax and oil and the characteristics that the solubility of wax in oil decreases with the decrease of temperature. Crystal wax is precipitated by cooling, and then filtered and separated to achieve the purpose of wax and oil separation. The dewaxing link is a process in the edible oil refining process. During the edible oil dewaxing process, the deodorized oil is sent to the crystallization tank of the dewaxing equipment, and frozen brine is passed into the coil of the crystallization tank to make the oil slowly crystallize to form a crystal nucleus. As the cooling process continues, the crystal nucleus slowly grows into crystal grains, slowly precipitates, and the crystallized oil is sent to the filter for filtration to be the finished oil.

Investment in camellia seed oil project, need to do a lot of work, first of all, to determine their own needs, processing how many tons of raw materials, output how much finished oil, finished oil to achieve a few grades of oil, these issues should be grasped clearly, for which Huatai intelligent equipment manufacturers can be equipped with the right equipment according to the needs of customers.
