Problems solved by technology

[0003] With the rapid development of the food industry, the demand for tea oil with high nutritional value is also increasing. At present, there are many oil extraction methods on the market, including hot pressing, chemical extraction and other methods. However, the traditional processing method, not only adding more additives, not green enough, but also when the selected Camellia oleifera seed oil is cold-pressed, a large amount of debris will be produced, which affects the oil yield and purity, resulting in the oil yield of Camellia oleifera seed being pressed. Low, there are many suspended solids / sediments in Camellia oleifera seed oil, and the oil quality is different, which is not conducive to improving market competitiveness

Embodiment 1

[0026] A cold-pressing oil-making process of camellia oleifera seeds, comprising the following production steps,

[0027] 1) Select 100kg of Camellia oleifera seeds, clean them of impurities, and screen the Camellia oleifera seeds with full particles and no insect eyes; in the process of cleaning impurities, select a sieve with an aperture of 4.2mm×15mm, and the diameter of the sieve surface is controlled at 2.4cm.

[0028] 2) Dipping: put the rapeseed prepared in step 1) into a sealed tank after vacuum disinfection, then add the mixed solution into the sealed tank, soak the rapeseed for 1.0 h in the sealed tank with the mixed solution, and take out the camellia oleifera Seeds are dried after being drained, and the moisture content of the dried Camellia oleifera seeds is lower than 45% for later use;

[0029] Wherein, the mixed solution is prepared according to the weight ratio of cell wall breaking enzyme:acid protease:alkaline protease:deionized water=4:2:1:20. The preparat...

Abstract

The invention discloses a camellia seed cold pressing oil producing technology which comprises the following manufacturing steps: 1) cleaning impurities of camellia seeds; 2) sending the screened camellia seeds into a sealed tank; 3) flaking: utilizing a roller flaking mill to roll the dipped camellia seeds into slices; 4) drying: drying the rolled camellia seed slices by hot air, setting a dryingtemperature as 30 DEG C to 40 DEG C and reducing moisture of the camellia seed slices to 2% to 4%; 5) pressing: sending the dried raw material into a twin-screw oil mill to be pressed to obtain oil,setting a temperature of the fed camellia seed slices as 5 DEG C to 35 DEG C and an outlet oil temperature as 45 DEG C to 55 DEG C and then utilizing a silvery filter screen to perform primary filtering; 6) separating oil from residues; 7) filtering and purifying the oil. According to the camellia seed cold pressing oil producing technology disclosed by the invention, a cold pressing method is utilized to produce oil, the whole process is performed at the low temperature, obtained cold-pressed oil is prevented from being further refined like general grease, and no any chemical additive is added into a processing process; thus, more greenness and environmental friendliness are achieved, and the whole processing method is simple and is suitable for batch production.

Description

technical field [0001] The invention relates to a process for producing oil by cold pressing, in particular to a process for producing oil by cold pressing of camellia oleifera seeds, and belongs to the technical field of agricultural product processing. Background technique [0002] Camellia oil made from camellia seeds is a high-quality edible oil with an unsaturated fatty acid content of more than 90% and does not contain erucic acid. It is more resistant to storage than other edible oils and is not easy to become rancid. Edible camellia oil not only does not increase the body's cholesterol, it is suitable for patients with hypertension, but also has health effects such as weight loss, blood fat reduction, and prevention of vascular sclerosis. Nutritional value of camellia oil with value. In addition, camellia seed has the effect of cleaning and removing greasy, so products such as camellia seed cleaning powder and shampoo have been widely used. Because it is a non-chemi...
