Abstract
The invention relates to an odor releasing process of a vegetable oil without residual moisture and the device. A coil pipe is arranged at the lower part in an operating room to let in high temperature hot air; an oil feeding pipe is throughout communicated to the part of a tank from the bottom part, and a valve arranged at the bottom part can ensure the oil to be directly sprayed to the upper part through a gear pump. Because of different processes, the traditional process achieves the purpose of odor releasing through distillation method, the process achieves the purpose of odor releasing through evaporating method, the foreign flavor molecule in the oil is vaporized into gas under heating condition, after the volume is enlarged and the density is decreased, the gas is positioned in the vacuum pipe at the top part at the upper part of the tank, therefore, the gas with foreign flavor is sucked out, and the purpose of odor releasing is achieved; because steam is not required, the equipment investment is reduced, and the shelf life of the produced oil is prolonged.
Description
Technical field
The present invention relates to vegetables oil complete processing and equipment, specifically is a kind ofly not have the residual vegetables oil of moisture and take off flavor technology and device.
Background technology
At present, the method that the vegetables oil traditional technology is taken off flavor is to feed high-temperature steam in the vacuum deodorization jar, and steam toward upper punch, by the effect of intensifying distillation, makes the peculiar smell in the oil take out of with steam after grease mixes.Owing to spray into steam, make W/O part increasing, thereby the quality guaranteed period of oil is shortened, in addition, in high temperature oil, spray into water vapor and can chemical reaction take place and generate carcinogenic substance, add water vapor simultaneously in the coil pipe and have the slow deficiency that heats up.
Summary of the invention
The purpose of this invention is to provide a kind of hot blast that adopts is to add thermal medium, does not have moisture or carcinogenic substance in the processing and produces and take off flavor outstanding effect vegetables oil and take off flavor technology and device.
It is such that the present invention adopts technical scheme: a kind of do not have the residual vegetables oil of moisture and take off flavor technology, may further comprise the steps:
(1) open vacuum pump, when vacuum tightness reach-0.05MPa after, the grease after the decolouring is introduced in the vacuum work chamber;
(2) hot blast is introduced in the water back in the working chamber, grease in the working chamber is heated, wherein tea seed oil is warmed to 140 ℃, and hydrogenated oil and fat is warmed to 204 ℃~246 ℃, the starter receiver pump, deep fat is extracted out from the working chamber bottom, be pumped via pipes into again, through oil inlet pipe rise by shower nozzle in the ejection of working chamber top, fall after rise, make that grease fully stirs in the working spaces, open toothed gear pump 2 time 4-8 hour, whole vacuum of taking off the flavor process must keep negative pressure 0.09MPa~0.095MPa; The top of the working chamber oil returning tube by the band valve is communicated with the size of regulating sprinkler pressure by the valve of adjusting oil returning tube with oil inlet pipe;
(3) take off flavor and stop preceding 10 minutes, stop hot blast heating, below the cooling work cavity temperature to 70 ℃; Close vacuum pump then, open vacuum interface 5, toothed gear pump pumps and takes off flavor oil.
Device provided by the invention is to realize by such technical scheme, and promptly a kind of tea seed oil takes off the flavor jar, comprises having vertical working chamber that the top cover of working chamber is provided with the vacuum Link Port, is provided with heating coil in tank body; It is characterized in that: the center in working chamber is extended from bottom to top and is provided with oil inlet pipe, and the lower end of oil inlet pipe connects flowline by valve, and the working chamber bottom is connected with toothed gear pump and flowline by the pipeline of band valve.
The inlet side of described heating coil connects cooling water inlet pipe and hot-air inlet pipe respectively by valve.
Compare with the production technique of existing device, technique effect of the present invention is very tangible: traditional technology is in the bottom of jar nozzle to be arranged, and steam is in the nozzle place pressurized fast rise that makes progress, and the oil that drives the bottom rises and sprays on top; Can not make oil in the top ejection if the deodorizing tank of traditional technology is pressed into oil with toothed gear pump, because to this section of pasta oil the oil of toothed gear pump ejection is had resistance at nozzle, the while nozzle is little, and the pressure of the oil that comes out is naturally little; The present invention sprays into oil and takes off a flavor jar top, working spaces, does not have resistance naturally and can spray.On pressure was regulated, traditional technology was to regulate the steam pressure size by adjusting valve, and this device is to regulate the size that the valve of oil returning tube is regulated sprinkler pressure.
This device feeds high-temperature hot-air (more than 200 ℃) oil and heats up rapidly in coil pipe, thereby do not need steam that facility investment is reduced, the prolongation of guaranteeing the quality of the oil of producing, because technology is different, traditional technology is to reach the purpose of taking off flavor by distillating method, and this technology is to reach the purpose of taking off flavor by the method for evaporating, owing to evaporating, the band peculiar smell molecule in the oil becomes gas under heated condition, volume increases and density reduces, nature is on the top of jar, since jar the top vacuum pipe is arranged, thereby will be with the gas sucking-off of peculiar smell, thereby reached the purpose of taking off flavor; Thereby owing to do not need the steam facility investment to reduce, the quality guaranteed period of the oil of producing prolongs.
