The utility model discloses the operation controllability is strong, can throw the material in succession, and the crystallization cycle is short, and the crystallization is appeared fully.
Description
Technical Field
The utility model belongs to the grease separation field, more specifically the grease wax separator that a developments refrigeration crystallization dewaxed degreases that says so relates to.
Background
The tree moss absolute is a rare spice used for flavoring food and tobacco, is extracted from natural plant moss, and is extracted from dried tree flowers by alcohol to form paste, then the paste is extracted by petroleum ether to obtain a plurality of moss crude oils, and the moss crude oils contain lipid wax, and finally the moss crude oils are dissolved by alcohol and then are subjected to freezing crystallization, and the moss absolute can be obtained after dewaxing and degreasing.
Referring to natural mint and cineole freezing technology, the characteristic of the product is different from that of tree moss crude oil, the mint cells slowly crystallize, but the crystals of the mint cells are rhombohedral regular crystals which can be directly crystallized by a freezing method by using 85% oil, when the critical temperature is reached by crystallization, the oil is well separated from the crystals, the crystals of the cineole are microparticles which can be separated out at 0 ℃ or below, the crystallization can be directly recrystallized as long as the content of the eucalyptus oil is increased to 90%, the crystallization can be carried out by centrifugation after the crystallization, but the solid eucalyptus crystals can be dissolved at more than 0 ℃, so the crystallization separation needs to be under the condition of 0 ℃, but the tree moss crude oil has large viscosity and can be recrystallized after being diluted by alcohol, and the lipid wax in the tree moss crude oil is not formed fine powder which is pasted and packed, the separation is difficult after the freezing, the static crystallization method has poor effect, and the lipid in the oil often appears, the fragrance of the product is unstable, the efficiency is not high, and the research of a dynamic crystallization method is maintained, and oil and fat wax are separated through multi-stage crystallization.
Disclosure of Invention
The utility model discloses the controllability is strong during the operation, can throw the material in succession, and the crystallization cycle is short, and the crystallization is appeared fully, and the smooth finish of product, the purity all have obvious improvement than originally, and the oil yield has also obviously improved, has highlighted the peculiar green taste of tree moss absolute oil and pine fragrant flavor more.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the separation process comprises the following steps: diluting tree moss absolute oil with shout fat wax with anhydrous alcohol to obtain 25% tree moss alcohol solution; step two: the freezing mode under the dynamic condition is adopted, the cold adsorption of the crystallization rod is slowly carried out by utilizing different temperature differences of a plurality of towers, the crystallization gradually separates out solids, so that the grease in the tree moss is pure, and the purpose of oil separation is achieved; step three: the fat and wax are separated out on the crystal bars of each tower, and the oil falls into the alcohol.
Preferably, the separation device adopts four coil condensation crystallization towers 1 connected in series, the coil condensation crystallization tower 1 is provided with an observation mirror, the coil condensation crystallization tower 1 is internally provided with a thorn-shaped induction cooling coil 2, and the temperature parameter of the coil condensation crystallization tower 1 is adjustable.
Preferably, in the second step, the four-stage temperature is set to ensure that the crystals can be gradually precipitated and the lipid wax can be captured in a cold manner at different temperatures, wherein the four-stage temperature is 0 ℃ to-4 ℃ in the first stage, minus 4 ℃ to-8 ℃ in the second stage, minus 8 ℃ to-12 ℃ in the third stage, and minus 12 ℃ to-16 ℃ in the fourth stage; the four-stage temperature respectively corresponds to the temperature in the four coil pipe condensation crystallization towers 1.
Preferably, two viewing mirrors 3 are arranged on the tower wall of the crystallization tower 1 and used for observing the crystallization condition of the internal cooling coil 2.
The utility model discloses beneficial effect:
the utility model discloses the controllability is strong during the operation, can throw the material in succession, and the crystallization cycle is short, and the crystallization is appeared fully, and the smooth finish of product, the purity all have obvious improvement than originally, think that the existence has tree moss aucklandia root special flavor.
