The invention belongs to the method and apparatus field that tea seed prepares tea-seed oil and by product and extract thereof, especially belong to a kind of tea seed and prepare the method that tea-seed oil, by product tea waste and by product tea waste extract tea-polyphenol, and the specific equipment that in these preparations, adopts.

Background technology:

Tea oil tree is China distinctive woody edible oil material seeds, also is one of four large woody edible oil source seeds in the world.Tea-seed oil is " uniquely can compare favourably with sweet oil, in the world one of the most healthy edible oil ".The tea seed contains grease 26%~39%, and according to rough Statistics, the annual production of present national tea seed is about 1,200,000 tons, but produces only 15~180,000 tons of hair tea-seed oils per year.The camellia seed oil process for processing has two large techniques, and one is squeezing process, and two is extract technology.The rear tea seed cake of oil, tea waste are got in now widely used squeezing, and resid amount is generally 5%~9%.And at present tea seed (the following tea seed that claims) prepare the method for tea-seed oil and by product tea waste extraction tea-polyphenol, saponin method and the equipment that wherein will use as follows:

1) screening: tea seed will carry out the screening of tea seed fresh fruit before process for processing, screen available blower and artificial screening and combine, and removes impurity during screening, damages by worms and mould decayed fruit.

2) oven dry: the tea seed fresh fruit enters baking operation through after drying screening, and the baking room temperature is controlled at about 100 degree, and the length of drying time will be decided according to the raw material humidity, and dryness fraction can be come out of the stove after reaching 98%, enters the following broken program of peeling off.

3) peel off broken apart, pulverize out the tea seed powder: the tea seed of coming out of the stove after cooling, the fragmentation of can peeling off, the broken available decorticator of peeling off reaches benevolence, shell separates, and then camellia seed kernel is ground into the tea seed powder.One is disc type, toothed roller type, paddle type mill etc. for the decorticator that present China commonly uses, and these several decorticator volumes are large, and structure is complicated, and power consumption is more greatly that tooling cost is higher.Because tea seed is much bigger than the shell flintiness of other conventional oilseeds, and size is generally also inhomogeneous, utilizes the existing decorticator of existing market to peel off, and hulling rate and follow-up benevolence, shell separating effect are all not ideal enough.The used pulverizer of pulverising step is existing installation.

4) tea seed powder boiling: the tea seed powder of the pulverizing food steamer of packing into is carried out boiling, after boiling is well-done, can wrap cake.The boiling of tea seed powder, to destroy the free radical in the tea seed powder, tea-seed oil is easily squeezed out, but present tea seed powder steaming plant does not have temperature regulating device, can not guarantee the boiling under best boiling temperature of tea seed powder, cause local superheating, thereby cause the tea seed powder not high by the oil yield that oily crusher presses into tea-seed oil, and wasted a large amount of excessive heat and waste energy.

5) bag cake: the tea seed powder that cooks is inserted the iron ring of having got ready be bundled into pie, put into squeezing machine and squeeze.

6) tea cake squeezing: after the tea cake was filled squeezing machine, the squeezing of can driving was at first driven low pressure valve and is squeezed during squeezing, when the full lattice of low pressure valve stroke, get final product the opening high pressure valve, want order progressive during squeezing, according to the continuous supercharging of fuel-displaced situation, top pressure can reach more than 100 tons.The squeezing of tea cake obtains tea-seed oil, and squeezing by product tea waste.

7) the by product tea waste extracts the products such as tea-polyphenol, saponin: contain tea-polyphenol, saponin about 10%~15% in the by product tea waste of tea cake after oil expression, the tea waste after the oil expression is the optimum feed stock of extracting tea-polyphenol, saponin.Tea saponin is a class glycoside compounds, basic structure by triterpenoid saponin, structure sugar, structure is sour forms, and is a kind of good surface promoting agent of natural non-ionic type, has the kinds of surface activity such as emulsification, dispersion, moistening, foaming and steady bubble.When pressing into tea-seed oil by oily crusher, the tea seed stayed numerous tea waste, these tea waste can extract tea-polyphenol, saponin etc., but tea seed cake is block object, must pulverize and to use, and the pulverizer that uses at present mostly is the broken formula structure of hammer sieve formula or dragon, their disadvantage is after comminuting matter enters body, no matter the pulverized particles size is all from discharge hole for discharge, also no matter granular size is also carried out repetitious hammering sometimes, mill is pressed, must need larger power like this, the loss mass energy; Secondly, existing hammer crusher is in pulverizing running work, under the powerful running dynamic action of hammer leaf, the part comminuting matter is often occurred by the opening for feed phenomenon that of getting rid of outward, choke, the particle that throws away is large, as easy as rolling off a logly injures operator, if fine particle vomits, the dust concentration of workplace increases, and Working environment will be very abominable.

The pharmacological actions such as in addition impervious, the anti-inflammatory of tea-polyphenol, saponin, analgesia, and sterilizing pesticide is arranged and stimulate the function of certain plants growth.Therefore, tea saponin is widely used in the industries such as daily-use chemical industry, weaving, medicine, agricultural chemicals, foodstuffs industry and building, and potentiality to be exploited is very large, and estimation can be developed 180 multiple products.Extract the remaining dregs of rice of tea saponin, contained more rich protein, starch and xylogen, mineral element, slightly done processing and namely can be used as fowl, poultry, fish meal, realized appreciating and enlarging of the remaining dregs of rice.

Therefore, squeezing is got the extraction of the Residual oil of tea waste and tea-polyphenol behind the oil, saponin and can avoid the waste of resource, have great importance for improving added value.

At present, conventional tea-polyphenol, saponin extracting method are water extraction methods, and the resulting tea-polyphenol of this method, saponin purity are low, containing water-soluble impurity is many, brown color, water makes much starch gelatinization, the protein colloid in the tea seed in leaching process, causes the solid-liquid separation difficulty, and the product water-absorbent is very strong, toughness requires drying temperature high, tends to make tea-polyphenol, the rotten decomposition of saponin, color burn is used this method poor effect.
