Description
Technical field
The utility model relates to a kind of Carapax Eriocheir sinensis extraction element, belongs to biological plant technical field.
Background technology
The crab resources of China is abundant, is the bulk crab meat processing canned crab meat of getting under its chest shell of collection and in large chela to the main processing of crab, and what also have is processed into the products such as crab paste, crab cream paste, crab oil and crab seasoning.In crab processing, produce many leftover bits and pieces, comprise bound feet and a large amount of crab shell of crab.Crab shell is the primary raw material of producing chitin, in crab shell, chitin content is up to 58 ~ 85%, that chitin has is anticancer, suppress cancer, oncocyte shifts, improve body immunity and liver detoxification effect, be particularly useful for the diseases such as diabetes, liver-kidney diseases, hypertension, obesity, be conducive to prevent cancer cell pathology and chemoradiation therapy treatment tumor disease etc., based on above advantage, from crab shell, chitin extraction is significant.
The extraction element of chitin extraction includes independently sour tank and alkali tank at present, and acid is carried rear alkali and carried, and the alkali lye in the acid solution in sour tank and alkali tank all needs to focus on separately, and treatment step is many, complicated operation, and the duration is longer; In addition, because the chitin after Carapax Eriocheir sinensis extraction is neutral mucopolysacchauide, be high molecular weight material, its molecular weight can reach more than 1,000,000, therefore be all difficult to dry or be difficult to completely dry as hypobaric drying method, far-infrared drying method, electrical drying method with common drying means.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of alkali liquid tank to be positioned at sour tank, can in sour tank, adjust extracting liquid pH value and extract the good Carapax Eriocheir sinensis extraction element of gained material chitin drying effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Carapax Eriocheir sinensis extraction element, it is characterized in that: the liquid outlet of sour tank is connected with the inlet of settling tank, the precipitation outlet of described settling tank is connected with the inlet of water washing tank, and the liquid outlet of described water washing tank is connected with the inlet of centrifuge and the inlet of spray dryer respectively; In described sour tank, be provided with agitating device, acidity indicating gage and alkali liquid tank, described agitating device is positioned at the bottom of described sour tank, described alkali liquid tank is positioned at the top of described sour tank, on described alkali liquid tank, be also provided with and control the interstage valve that described alkali liquid tank is opened or closed, described interstage valve is by the switch control being positioned at outside sour tank.
In described sour tank, have concentrated acid extract, for extracting the chitin of Carapax Eriocheir sinensis, the stirring of agitating device is beneficial to the stripping of chitin, and recovery rate is improved, chitin extraction is to setting-up time, regulate again the pH value of concentrated acid extract, control method is: open the switch being positioned at outside sour tank, interstage valve is opened, the concentrated base that is arranged in alkali liquid tank flows into sour tank, under the stirring of agitating device, mix with concentrated acid extract, note according to the pH value after acidity indicating gage monitoring adjusting, in the time that pH value arrives setting value, closing switch, thereby close alkali liquid tank, complete the process of adjusting alkali, then under the solution condition after adjusting, continue to be extracted into after setting-up time, tapping is to settling tank, and settling tank is for precipitating the chitin extracting, because chitin is that acid-soluble alkali is heavy, therefore chitin becomes precipitation state from solution state after tune alkali, in settling tank, accelerate the precipitation process of chitin, after precipitation, supernatant is from the supernatant outlet sucking-off of settling tank, precipitation is discarded in water washing tank by precipitation outlet, be deposited in water washing tank and be washed to after neutrality, put into centrifuge centrifugal, get the precipitation after centrifugal, again put into water washing tank, washing again, after washing, put into again centrifuge centrifugal, and so forth, until water lotion is after neutrality, the inlet that sucks spray dryer after neutral water lotion stirs with precipitation will be, adjust flow velocity, the dried chitin that makes to spray is dry graininess, until all neutral water lotion and precipitation sprayings that be have been dried.
Described agitating device comprises paddle.
Described alkali liquid tank is positioned at the liquid level top of extract (being sour tank solution) all the time.
The material of acid tank inwall is acid-fast alkali-proof material, as ceramic pot.
Splendid attire concentrated alkali solution in described alkali liquid tank, described alkali liquid tank is also connected with flowmeter.
Flowmeter is used for the emitting rate of the concentrated alkali solution of controlling alkali liquid tank, avoids because the material to be extracted that the local alkalescence of liquid causes excessively is by force decomposed.
Described sour tank is outside equipped with acidity display.
Acidity display is for monitoring the pH value of sour tank internal solution.
On described settling tank, be provided with supernatant outlet and precipitation outlet, described supernatant outlet is positioned at the top of described settling tank, and described precipitation outlet is positioned at the bottom of described settling tank; The tank skin of described settling tank is hollow, fills cooling medium in the tank skin of described settling tank.
Described cooling medium comprises condensed water.
Condensed water the settling velocity of having accelerated settling tank is set, be beneficial to the rapid subsidence of shitosan.
Between described sour tank and settling tank, be also provided with infusion pump.
A kind of Carapax Eriocheir sinensis extraction element that the utility model provides, alkali liquid tank is positioned at the setting of sour tank, make that acid is carried, alkali is put forward technique and completed in a tank, and the solution after extracting only need be processed once, has removed the repeatedly imbibition between different extractors from, repeatedly clean, the repeatedly problem such as liquid waste processing, greatly simplify abstraction process and method of operating, effectively shortened the duration, be equivalent to improve production efficiency; In addition, the use of spray dryer, makes shitosan rate of drying fast, completely dry.A kind of Carapax Eriocheir sinensis extraction element that the utility model provides, simple in structure, easy and simple to handle, drying effect is good, and saving of work and time is applicable to wide popularization and application.
