2. the one-level dish leaves: yellow emulsion gets into the first-stage centrifugal machine through step after 1., regulates the weight phase pressure of first-stage centrifugal machine outlet, and making light and heavy phase pressure ratio is 2:1, and the oil-containing material is discharged on the lenient side mutually after spinning; The one-level dish is about 40% from the light phase export oil-contg, and the heavy out oleaginousness is not higher than 0.2%.
3. the secondary dish leaves: step 2. gained oil-containing material gets into the secondary whizzer, regulates the weight phase pressure of secondary whizzer outlet, and making light and heavy phase pressure ratio is 1.5:1, and the oil-containing material is discharged on the lenient side mutually after spinning; It is about 88% that the secondary dish contains oil-contg from light phase export, and the heavy out oleaginousness is not higher than 0.24%.
4. three grades of dish leave: step 3. gained oil-containing material gets into three grades of whizzers, regulates the weight phase pressure of three grades of whizzers outlets, and making light and heavy phase pressure ratio is 1:1, after spinning, discharges on the lenient side mutually, must the navel orange essential oil, and oleaginousness is not less than 99%.
Whizzer is a disc centrifuge.
Step 2. in, the water of discharging from heavy phase is through replenishing fresh water, control viscosity is no more than 5 centipoises, is circulated to step 1. as spray water.
Effect of the present invention is; The present invention is directed to the navel orange pericarp and comprise yellow thick materials such as pectin; Cause separating not smooth characteristic easily, Creative Design goes out the essential oil extraction process that three grades of dish leave, and first step dish is from oil-contg is concentrated into about 40% from about 1%; Second stage dish is from being concentrated into oil-contg about 88% from about 40%, and third stage dish is from oil-contg is concentrated into more than 99% from about 88%.Make the profit slag sepn process in each step be easy to control like this, final product purity is high, and quality is good.The separation efficiency of whizzer is relevant with feeding rate; The two-stage dish is brought up to high value from the separation requirement of system's the first step with orange oil concentration, thus must control feeding rate, otherwise separating effect can be bad; More orange oil can get into heavy phase and cause the reduction of productive rate; The control feeding rate causes production efficiency low, and three grades of dish help large-scale industrialization production from accelerating feeding rate to a certain extent.In addition, orange peel is rich in the yellow thick material that comprises pectin, and the highly enriched rate that the two-stage dish leaves can cause separating the obstruction of smooth even pipeline, and three grades of dish leave system owing to there is more buffering can avoid separating not smooth problem.
