Abstract
The invention relates to a manufacturing technique for adding hydrogen in soybean oil. Under the condition of dehydration temperaturre of 80oC and vacuum degree of - 0.1Mpa, the purchased soybean oil is processed until being qualified, and 820 catalyst with the usage amount of 0. 06% is added after measurement. The material is put into the reaction kettle by vacuum and height difference after even stirring. The temperature of reaction kettle is increased to 130oC through conduction oil. Under the action of catalyst, the hydrogenation reaction occurs between 99.95% hydrogen and soybean oil and the temperature drops over 3oC after reaching the peak. The materials are discharged, cooled, pressed and filtered to finally obtain the finished product. Advantages: it has high reaction efficiency and degree through the reaction of high-content hydrogen and soybean oil under the action of catalyst in the reaction kettle; and has easy operation, high automation degree and security coefficient together with small environmental pollution.
Description
Technical field
The present invention relates to oils and fats technical field, specifically, be that hydrogen and soybean oil are being reacted by a kind of catalyst that passes through
Still occurs the production technology of hydrogenation reaction.
Background technology
HYDROGENATION OF OILS AND FATS refers under the effect of catalyst, the unsaturated double-bond in oils and fats and hydrogen generation additive reaction, thus
Change the various physico-chemical properties of oils and fats, with satisfied production needs.After HYDROGENATION OF OILS AND FATS, saturation increases, and causes its oxidation stability to carry
High;Meanwhile, after edible oil and fat hydrogenation, color and luster, abnormal smells from the patient, mouthfeel frequently result in significantly improvement.The oils and fats of chosen hydrogenation
May generally serve as the raw material of shortening, margarine or cocoa butter substitute, there is higher economic worth.
Treated soybean oil is joined in reactor, by controlling initial reaction temperature, the work of activated catalyst
Property, then under the effect of catalyst, under specific reaction temperature and reaction pressure, accelerate on unsaturated fatty acid not
Saturated bond carries out hydrogenation rate, improves the degree of hydrogenation to unsaturated bond, and the iodine value of soybean oil drops to less than 1 the most at last.
Summary of the invention
In order to improve efficiency and the degree of hydrogenation of soybean oil hydrogenation, improve the utilization rate of the energy, adapt to up to date technics
Development, meet the demand in market, we have proposed a kind of soybean oil hydrogenation production technology:
Dehydration temperaturre be 80 DEG C, vacuum for-0.1Mpa under conditions of, it is qualified to be processed by the soybean oil of outsourcing, through metering
Rear addition usage amount is 820 catalyst of 0.06%, after stirring, utilizes vacuum and difference in height to squeeze in reactor by material,
Utilizing conduction oil that temperature of reaction kettle rises to 130 DEG C, under the effect of catalyst, content is hydrogen and the soybean oil of 99.95%
Hydrogenation reaction occurring, decrease beyond 3 DEG C after reaching maximum temperature, discharging cools down, and filter pressing finally gives finished product.
The operating procedure of the present invention is as follows:
Step one: one-level purified soyabean oil is joined in drain sump, temperature controls at 80 DEG C, keep vacuum be-
0.01Mpa, is dehydrated half an hour.
Step 2: the soybean oil being dehydrated is squeezed into head tank after metering, adds import 820 catalyst, stirs,
By reactor pulling vacuum, material is put in reactor.
Step 3: slowly open reactor conduction oil valve, heats to reactor, closes when temperature reaches 130 DEG C and lead
Deep fat valve, utilizes conduction oil waste heat that temperature is risen to 135 DEG C, opens hydrogen valve.
Step 4: control the rate of climb of reaction temperature, is maintained at normal condition (about 6 DEG C/min), controls reactor
Pressure is at below 1.0Mpa, after rate of rise in temperature declines, and increase reactor pressure to 2.0Mpa.
Step 5: when reaction temperature is more than 190 DEG C, open chiller, makes reaction temperature finally control on 230 DEG C of left sides
Right.When reaction temperature declines, i.e. reaction terminates.
Step 6: reaction terminates discharging, and control temperature of charge is at about 120 DEG C, and filter pressing temperature controls at 100-110 DEG C.
The useful point of the present invention is:
1, utilizing hydrogen and the soybean oil reaction kettle for reaction under the effect of catalyst that content is high, reaction efficiency is high, reaction interval
Degree height.
2, this operation is simple, and automaticity is high, and safety coefficient is high, and environmental pollution is little.
