Abstract
The invention discloses a completely continuous quick normal temperature dewaxing process and belongs to a corn oil production process. The dewaxing process is that: the corn oil overflows from a first crystallization tank, orderly passes through a plurality of crystallization tanks and finally reaches the last crystallization tank; during the overflow, the temperature of the corn oil is gradually decreased to between 4 and 6 DEG C, then the corn oil is made a thermal insulation for 3.5 to 4.5 hours, is crystallized and made a crystal growing, then the oil temperature rises to between 15 and 20 DEG C, the oil is filtered and dewaxed; with the dewaxing process, the wax in the corn oil can be fully crystallized, the dewaxing effect is good, and the quality of the corn oil is greatly improved. During the freezing test, the time that the corn oil produced by the prior process keeps clear and transparent is only six hours or so, but the time that the corn oil produced by the invention keeps clear and transparent is 30 hours or so, the filtering speed is quick, the filtering yield is high, and the yield can be improved by more than 30 percent.
Description
Technical field
The invention provides the technology in a kind of Semen Maydis oil production, especially a kind of dewaxing technique.
Background technology
In the Semen Maydis oil production process, the Semen Maydis oil that harsh output is come be carried out dewaxing treatment, to remove the wax that wherein contains.Present dewaxing technique is that Semen Maydis oil is cooled to about 5 ℃ in single crystallizer, and keeps filtering more than 6 hours again, finishes dewaxing.The crystallization of this technology wax is insufficient, and dewaxing effect is relatively poor, causes the quality of Semen Maydis oil lower, adopts filter at low temperature, and oil plant viscosity is big, and filtration velocity is slow.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of normal temperature fast dewaxing technique by total continuous method, to improve dewaxing effect.
The present invention realizes like this, normal temperature fast dewaxing technique by total continuous method, described dewaxing technique be, with Semen Maydis oil from first crystallizer through a plurality of crystallizers one by one overflow to last crystallizer, in flooding process, the temperature of Semen Maydis oil progressively is reduced to 4-6 ℃, is incubated 3.5-4.5 hour then and carries out crystallization, growing the grain, then, with oily temperature rise to 15-20 ℃, filter, remove wax, finish dewaxing.
Adopt this dewaxing technique, the wax in the Semen Maydis oil can be come out by sufficient crystallising, and dewaxing effect is good, has improved the quality of Semen Maydis oil greatly.In the freezing test process, keeping the as clear as crystal time with the Semen Maydis oil that has dewaxing technique production now only is about 6 hours, and the Semen Maydis oil of the present invention's the explained hereafter as clear as crystal time of maintenance is about 30 hours.And filtration velocity is fast, the throughput of filtration height, and output can improve more than 30%.
Embodiment
Further specify the present invention below.
In the temperature-fall period of Semen Maydis oil, earlier Semen Maydis oil is sent into first crystallizer, then by pipeline overflow to the second crystallizer, three crystallizers of overflow to the again, by that analogy, Semen Maydis oil through a plurality of crystallizers one by one overflow to last crystallizer.
Before Semen Maydis oil enters first crystallizer, can in Semen Maydis oil, add filtration adjuvant.This auxiliary agent is identical with auxiliary agent used in the existing dewaxing technique.
Oily temperature rise to 15-20 ℃, when filtering, is taked the slowly mode of rising of oil temperature.This filtration temperature is near normal temperature.
Claims (1)
1. normal temperature fast dewaxing technique by total continuous method, it is characterized in that described dewaxing technique is, with Semen Maydis oil from first crystallizer through a plurality of crystallizers one by one overflow to last crystallizer, in flooding process, the temperature of Semen Maydis oil progressively is reduced to 4-6 ℃, is incubated 3.5-4.5 hour then and carries out crystallization, growing the grain, then, with oily temperature rise to 15-20 ℃, filter, remove wax, finish dewaxing.
