Embodiment Construction

[0016] The present invention provides a novel refining and deodorizing method. In order to make the purpose, technical scheme and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] A preferred embodiment of a novel refining and deodorizing method provided by the present invention comprises the steps of:

[0018] Such as figure 1 As shown, after the oil product is heated to 240-250°C by the first heater 100, the specific heating temperature can be 240°C, 245°C or 250°C to improve the deodorization effect, and enter the top of the deodorization plate tower 110 for deodorization treatment , an oil drain valve is arranged in the deodorizing plate tower 110, and the oil product in the deodorizing plate tower 110 flows to the bottom of the deodorizing plate...

Abstract

The invention discloses a novel refining deodorization method which comprises the following steps: an oil product is arranged at the top of a deodorization plate tower after the oil product is heated to 240-250 DEG C through a first heater, an oil draining valve is arranged in the deodorization plate tower, the oil product in the deodorization plate tower flows to the bottom of the deodorization plate tower through an overflow valve or the oil draining valve; the oil product is thrown into the top of a deodorization filler tower, wherein filling materials which are used for removing free fatty acids in the oil product are arranged in the deodorization filler tower so that the oil product overflows to the bottom of the deodorization filler tower after being treated by the filling materials so as to obtain the final refined oil; and the oil is discharged. According to the novel refining deodorization method, the deodorization filler tower is additionally arranged to rapidly remove the free fatty acids in the oil product, so that the refined oil product which is low in trans acids and low in free fatty acids is prepared, and the product quality is enhanced.

Description

technical field [0001] The invention relates to the field of refining and deodorization, in particular to a novel refining and deodorizing method. Background technique [0002] In the refining deodorization section in the prior art, the decolorized oil enters the top heater of the deodorization tower (plate tower) to be heated, and after heating, it overflows to the bottom layer layer by layer, and then the oil is discharged through the shielded pump to complete the deodorization of the oil product. [0003] The disadvantage of the existing refining deodorization process is that the residence time of the oil product in the plate tower can only be determined by the flow rate, which cannot be flexibly controlled. In addition, when producing oil products with low trans acidity, it is necessary to reduce the temperature to achieve , but its free fatty acid content cannot meet the requirements after the temperature is lowered, so the trans acid content is still high. [0004] Th...
