However, this method is inefficient. It takes 48-60 hours for the saturated ester to freeze at low temperature. In addition, because the crystals are thin and dispersed, the time for the material to be filtered on the filter press is long, which not only reduces the processing efficiency but also easily causes damage to the filter paper. A large amount of filter paper increases the processing cost, and it is easy to cause incomplete filtration. Impurities such as pulp are also easily mixed into the camellia oil, which reduces the quality of the camellia oil.

Embodiment Construction
[0015] Such as figure 1 The high-efficiency winterization equipment for camellia oil shown includes a tank body 10, which is a common vertical structure, that is to say, the shaft core of the tank body 10 is arranged in a vertical direction, and an oil inlet valve is arranged on the top of the tank body 10 11. An oil outlet valve 12 is arranged at the lower end of the tank body 10, and the oil outlet valve 12 is arranged at the lower end of the tank body 10 to facilitate the discharge of camellia oil or other similar materials. The tank body 10 is also provided with a condenser 14 for condensing the camellia oil in the tank and an agitator 13 for stirring the tea oil in the tank, and the agitator 13 is also a vertical structure, such as figure 1 As shown, the motor of the agitator 13 is fixed on the upper end wall of the tank body 10, the stirring shaft of the agitator 13 is arranged along the axis core of the tank body 10, and the condenser 14 includes a condensation pipe for...

The invention aims to provide an efficient winterization device and an operation method of tea oil. The device is composed of a tank body, a condenser and a stirrer, wherein the tank body is provided with an oil inlet valve and an oil outlet valve; the condenser is used for condensing materials in the tank; and the stirrer is used for stirring the materials in the tank. The device is characterized by also comprising a seed crystal thrower for adding seed crystals. The winterization method has the following steps: injecting the materials into the tank body, cooling the materials at the temperature of 9 DEG C under a stirring condition, adopting the seed crystal thrower to throw a proper amount of seed crystals in the materials, and continuing to stir and cool; and preserving the temperature for above 24h when the temperature of the materials are cooled to 0 DEG C, heating the materials to 5 DEG C, discharging the materials from the oil outlet valve, and filtering to obtain filtrate as the product in the invention, wherein the seed crystals are solid powders difficultly soluble in the materials and difficult to produce chemical reactions with the materials. Due to trigger action, the seed crystals can accelerate freezing and crystallizing of saturated acid ester in the tea oil, and crystals are filtered out to realize tea oil purification, thus improving winterization processingefficiency of the tea oil.
Description
technical field [0001] The invention relates to the processing of camellia oil, in particular to an equipment used in the winterization treatment of camellia oil and a process method of the winterization treatment. Background technique [0002] Camellia oleifera seed oil is referred to as camellia oil for short, which contains a certain amount of saturated esters (solid fats with high melting point, such as hard fatty acids, waxes, etc.), and flocs will appear when stored at low temperature, which will affect its appearance quality. The purpose of tea oil purification is to increase the content of unsaturated fatty acids such as oleic acid in the product, reduce the content of saturated fatty acids, especially hard fatty acids, and remove waxes and other undesirable substances in the oil. The existing camellia oil purification technology uses the characteristics of different substances with different freezing points, freezes the camellia oil, and filters its crystalline subs...
