Description
Technical field
The present invention relates to the food oils refining and deodorizing workshop section of food oils processing technique field, specifically a kind of grease deodorization device and deodour method thereof and filler stripping pump mechanism.
Background technology
In the food oils course of processing, because the metal ions such as the oxygenizement of air and iron, copper are followed a small amount of water in grease, impel grease corruption, thereby produce the materials such as lipid acid, alcohol acid simultaneously, also may cause the rotten of protein, produce thus stink.Therefore,, for the course of processing of food oils, having a crucial step is exactly deodorization.
So-called deodorization is the difference of utilizing the volatility of the interior stink substance of grease and tri-glyceride, removes the technological process of stink substance under high temperature high vacuum condition by wet distillation.Stink substance in grease mainly contains low molecular aldehyde, ketone, free fatty acids, unsaturated hydro carbons etc.Deodorization not only can, except the stink substance in deoiling, improve the smoke point of grease, improves the local flavor of edible oil, can also remove superoxide and degradation production thereof.
At the same temperature, the steam of various stink substances is pressed with larger difference, and in general the deodorization of grease need to be carried out at the temperature of 200～280 degree and under the vacuum tightness of 1～6mbarA.
Therefore, we need a kind of deodorization equipment, under the condition of high temperature and high vacuum, carry out grease deodorization.
The deodorizing tower that traditional refining and deodorizing workshop section of Vegetable oil lipoprotein processing factory adopts adopts following form conventionally:
(1) column plate tower:
Vegetables oil is distributed on tower tray, on tower tray, be furnished with open steam coils, when work, by open steam coils, Xiang Tazhong passes into open steam, stink substance in open steam and grease, rise to liquid layer surface from tower tray bottom together, then on surface, vegetables oil is separated with stink substance, this column plate tower deodorization efficiency is very low, most open steam bubble, also do not rise to oily surface, just break, therefore most steam does not play due effect;
(2) improve column plate tower:
In order to overcome the shortcoming of the column plate tower proposing in (1), someone is taking column plate tower as basic structure, the equipment that one is commonly called as " mammoth pump " is installed on tower tray, this mammoth pump is made up of stripping pump and distribution cap, the oil of tower tray bottom is risen to top by stripping pump, clashes into distribution cap, and then realize the gentle gas-liquid separation of oil, in long deodorization time, the oil quality of processing is stable.Although but this tower has improved the utilising efficiency of open steam, separating area is limited after all, need to lean on long deodorization time to reach the deodorising effect of anticipation, deodorization efficiency is still lower;
(3) packing tower:
In order further to improve the separation efficiency of grease, packing tower is introduced into the deodorization of grease.Someone is referred to as " soft tower ", and because packing tower has great specific surface area, deodorization efficiency is greatly improved, but due to the characteristic of packing tower, the time of grease deodorization is very short, cause oil product refining after quality very unstable, easily there is the problem of color reversion aftertaste;
(4) packing tower plates combined column
In order to improve the unsettled problem of above-mentioned oil product, someone proposes a kind of so-called " combined column " again, and its structure is, adopts the structure of packing tower in upper part of tower, adopts in lower part of tower the structure of improving column plate tower; So, this tower had both utilized the characteristic of the efficient depickling of packing tower, had utilized again the long advantage of column plate tower deodorization time simultaneously.But such problem of pressure drop of bringing again packing layer, causes the vacuum tightness of lower part of tower poor, therefore oil quality is out unstable, and the problem of color reversion and aftertaste easily occurs;
(5) in order to overcome the shortcoming of above-mentioned packing tower plates combined column, someone invents " cellular-type tower " again, be characterized in one section of column plate tower to be divided into two chambers in diametric(al), a chamber is arranged to packing tower, another chamber is arranged to column plate tower, processed oil carries out secondary deodorization at column plate tower going out before tower under lower vacuum, so just utilize the efficient depickling of filler, the pressure drop of packing layer simultaneously can not have influence on again the vacuum tightness in tray column, this design improvement the shortcoming of combined column, but this tower adopts semicircle filler, device structure complexity, inconvenient maintenance, and the cost of equipment is more expensive.
