Problems solved by technology

[0003] The general tea oil preparation process mostly adopts direct pressing after steaming, or supercritical carbon dioxide extraction. The former has low cost for preparing camellia oil, but the oil yield is low, while the latter has high oil yield, but the cost is relatively high, and In actual operation, the camellia oil prepared by the former has a stronger fragrance, but relatively more impurities, and in the existing detection, it can be known that the main flavor substances in the tea oil are nonanal, hexanal, octanal, trans-2- Nonenal and 2-pentylfuran, so choosing a processing technology that can effectively retain these flavor substances can effectively improve the fragrance of tea oil
[0004] This application adopts the combined method of pressing and extracting to make oil from the raw materials, while most of the processing of camellia oleifera seeds in the existing devices adopts single pressing or single extraction, and there is no device that combines pressing and extracting, so the existing device is used for this process. The preparation of the requested camellia oil is time-consuming and labor-intensive, which will easily cause the loss of camellia oil and bring some troubles to the actual production

Abstract

The invention provides a process and a device for processing tea oil with rich fragrance, and relates to the technical field of tea oil processing. The processing technology mainly comprises the steps of raw material selection, shelling treatment, tea seed shell treatment, crushing and uniform wetting, low-temperature puffing, curing preparation, squeezing extraction, refining and impurity removal and the like. The oil yield of tea seeds is effectively improved, meanwhile, aromatic substances in the tea oil are greatly reserved, and the flavor of the tea oil is improved; the tea oil seeds can be effectively squeezed and then extracted by using the tea oil squeezing and extracting combined device, two-step operation is realized by using a single device, waste of manpower is effectively reduced, and squeezing and extracting are used in the same device, so that the dissipation of flavor substances is prevented, and the fragrance of the tea oil in the later stage is improved.

Description

technical field [0001] The invention relates to the technical field of camellia oil processing, in particular to a process and device for processing rich-flavored camellia oil. Background technique [0002] Camellia oil is a kind of edible vegetable oil with high quality, high nutritional value and easy to be digested and absorbed by human body obtained through processing and refining of Camellia oleifera seed. It is a pure natural green health food, which can effectively lower cholesterol, prevent coronary heart disease, high blood pressure and other cardiovascular and cerebrovascular diseases. Tea oil is rich in natural antioxidant substances, including vitamin E, polyphenols, squalene, etc. [0003] The general tea oil preparation process mostly adopts direct pressing after steaming, or supercritical carbon dioxide extraction. The former has low cost for preparing camellia oil, but the oil yield is low, while the latter has high oil yield, but the cost is relatively high...
