Abstract
The utility model discloses a maize oil deodorization device, including two heaters, combination tower and soft tower, combination tower top is equipped with oil inlet I, the bottom is equipped with oil -out I, and heater I links to each other with the oil inlet I of combination tower through oil pipeline, and oil -out I links to each other with heater II through oil pipeline, soft tower top is equipped with oil inlet II, the below is equipped with oil -out II, and heater II links to each other with the oil inlet II of soft tower through oil pipeline, and the oil -out II of soft tower is connected with the filter through oil pipeline. The deodorization device, to maize oil heat earlier, the deodorization, and then carry out secondary heating, deodorization, through two heating, deodorization for the content of aliphatic acid further reduces in the maize oil, has improved the quality of finished product maize oil.
Description
Technical field
The utility model relates to grease production apparatus field, especially a kind of Semen Maydis oil deodorization device.
Background technology
Refining of maize oil technique: crude oil → alkali refining → decolouring → dewaxing → deodorization → processed oil, each link has its unique and importance, indispensable.Deodorizing technology is except removing the stink substance in Semen Maydis oil, improve the smoke point of grease, improve the taste of Semen Maydis oil, free fatty acids, superoxide and some thermo-sensitivity pigments can also be removed, the volatile decomposition thing of protein in the mildew and rot oil plant of removing, the polycyclic aromatic hydrocarbons of removing small-molecular-weight and remains of pesticide are thus relatively high to the requirement of deodorization device.
Existing deodorizing technology adopts combined column to carry out deodorization mostly, and the top of built-up type deodorizing tower is packing section, and depth of packing is about 3 meters, and bottom is board-like section, and these two portions are two independent tower bodies, need the pipeline communication by Valve controlling.The major function of packing section is depickling, and the major function of board-like section is deodorization and heat decoloring, and deodorization temperature general control is at about 260 °, and deodorization time is about 1.5 hours.But the free fatty acids that such deodorizing tower is deviate from is thorough not, and the color reversion outstanding problem of processed oil, has a strong impact on the quality of Semen Maydis oil.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Semen Maydis oil deodorization device, and this device carries out twice deodorization by adopting two warm double tower, removes free fatty acids further, content of trans fatty acids in the processed oil obtained obviously is reduced.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Semen Maydis oil deodorization device, comprise two well heaters, combined column and soft tower, be provided with oil-in I above described combined column, bottom is provided with oil outlet I, well heater I is connected with the oil-in of combined column by oil pipeline, oil outlet I is connected with well heater II by oil pipeline, be provided with oil-in II above described soft tower, below is provided with oil outlet II, well heater II is connected with the oil-in II of soft tower by oil pipeline, and the oil outlet II of soft tower is connected with strainer by oil pipeline.
Described combined column comprises the packing tower on top and the tray column of bottom, and the depth of packing of packing tower is 3-5 rice, and deodorization time is 1-3 hour, carries out the long-time deodorization of low temperature.
The Heating temperature of described well heater I is 220-260 DEG C, and heat-up time is 1-10 minute.
The Heating temperature of described well heater II is 250-280 DEG C, and heat-up time is 1-10 minute, carries out second time high temperature flash desorption, removes the material such as pigment, lipid acid further.
The depth of packing of described soft tower is 4-7 rice, and deodorization time is 1-10 minute, then carries out high temperature flash desorption, makes the inverse test of processed oil better.
A tubular heat exchange is set up in the middle of described soft tower and strainer, soft tower deodorization deep fat out enters interchanger and power soft water carries out heat exchange, utilize the temperature of deodorization deep fat to the soft water heating entering workshop, improve soft water temperature, reduce deodorization hot oil temperature, cooled deodorised oil enters strainer again and is for further processing.
The beneficial effects of the utility model are: deodorization device described in the utility model, Semen Maydis oil is first heated, deodorization, and then carry out second-heating, deodorization, by twice heating, twice deodorization, the content of lipid acid in Semen Maydis oil is reduced further, improves the quality of finished product Semen Maydis oil.The packing tower thickness on combined column top increases, and extends filtration time like this, improves deacidification effect, improve finished product cast of oil.
Accompanying drawing explanation
