Abstract
A kind of method that the saturated vapor deodorization of nitrogen deodorization substitution reduces oil peroxidation value, the present invention is deodorized substitution conventional vapor using nitrogen and is deodorized, and use deodorizing technology, deodorization processing is carried out to grease, to propose a kind of method that the saturated vapor deodorization of nitrogen deodorization substitution reduces peroxide value.The problem of the purpose of the present invention is to solve oil peroxidation value increases after steam deodorization, compared with traditional steam deodorization, oxygen content is 50ppb=50000 μ g/mL in conventional vapor, and the oxygen content being passed through in pure nitrogen gas (99.9%) only accounts for 10ppm=10 μ g/mL or so, and the oxygen content far smaller than in steam, so being deodorized substitution steam deodorization using nitrogen, the peroxide value of grease is reduced, provides theoretical direction for food processing security fields.
Description
Technical field:
A kind of method that the saturated vapor deodorization of nitrogen deodorization substitution reduces oil peroxidation value, belongs to food safety technology
Field.
Background technique:
The process of deodorization, the continuous development through last 100 years, it has also become one of increasingly important technique.It is handled by deodorization
Oil and fat smoke point improve, edible flavor is improved, peroxide and its decomposition product, the polycyclic aromatic hydrocarbon of small-molecular-weight, residual
The harmful substances such as pesticide can effectively remove, and provide reliable guarantee for people's health.It is domestic to mostly use saturated vapor de- greatly
Smelly method, but the shortcomings that such saturated vapor deodour method, is: contain micro oxygen in saturated vapor, when grease heats
To 250 DEG C, cause grease that serious oxidative phenomena occurs, so that oil peroxidation value increases.
Summary of the invention:
The present invention substitutes traditional saturated vapor using nitrogen deodorization and is deodorized, and uses deodorizing technology, is deodorized to grease
Processing, so that a kind of method that the saturated vapor deodorization of nitrogen deodorization substitution reduces oil peroxidation value is proposed, it is de- by controlling
Smelly temperature, deodorization time are deodorized nitrogen Ventilation Rate parameter, comprehensively consider these parameters and imitate to oil peroxidation value and deodorization
Fruit.Object of the present invention is to solve the problems, such as that oil peroxidation value increases in saturated vapor deodorization, and select the combined type in attached drawing
Formula deodorizing tower carries out deodorization processing to soybean oil, and the substance for making ketone, aldehydes etc. have higher vapor pressure is largely combining
It is removed in formula deodorizing tower, and makes high boiling fatty acid, hydrocarbons removing；Compared with traditional saturated vapor deodorization, nitrogen
Oxygen content be far smaller than the oxygen content in steam, oxygen content is 0.1mg/L=100 μ g/mL in conventional vapor, and is passed through height
Oxygen content in purity (99.999%) only accounts for 3ppm=3 μ g/mL or so, so it is de- to be deodorized substitution saturated vapor using nitrogen
Smelly, the present invention largely reduces the oxygen content in deodorizing tower, reduces the degree of oxidation of grease, thereby reduces grease
Peroxide value, improve the quality of product oil, provide theoretical direction for food processing security fields.
Combined type formula deodorizing tower working principle
The top of combined type deodorizing tower is packing section, and lower part is board-like section.Oil enters at the top of combined type deodorizing tower, leads to
Excessive food tray is evenly distributed in formation oil film on filler and flows from above to below, and the stripping superheated steam with adverse current is on filler
Vapour-liquid inversely contacts, and distills out fatty acid and a part of malodor components in packing section first, is taken away by vacuum, and oil passes through again
Pipeline flows into board-like section.Steam in board-like section, in shape ejection is bubbled, carries out contact stripping, oil directly from oil with oil again
The boiling point of stink substances is reduced by high vacuum in board-like section, and by the distillation of superheated steam, to reach the mesh of deodorization
, and it is detained carry out heat decoloring, deodorised oil is discharged from deodorization tower bottom.
The packing section of combined type deodorizing tower and board-like section are two individual tower bodies, pass through the pipeline connection that valve controls.
The major function of packing section is depickling, and board-like section of major function is deodorization and heat decoloring.When processing low acid value oil product, decoloration
Oil is not required to through packing section depickling, and is directly entered board-like section of stripping deodorization by oil inlet pipe.
Detailed description of the invention: Fig. 1 combined type deodorizing tower structural schematic diagram
It include oil inlet, direct gas import, conduction oil outlet, oil outlet in Fig. 1
