1. A kind of 1. method that carragheen is prepared using ceramic membrane filter method, it is characterised in that it comprises the following steps:

  • (1) OK a karaoke club collagen solution is preparedBy Eucheuma after alkali process, cleaning and steam digestion, pearlite filtering aid is added, then remove by plate and frame filter pressImpurity, obtains OK a karaoke club collagen solution;

    (2) ceramic membrane filterBeing connected using the two-stage ceramic membrane filter equipment that aperture is 20~200nm, it is dense that OK a karaoke club collagen solution is continuously filteredContracting, obtains the concentration filtrate of concentration 2%;

    The two-stage ceramic membrane filter equipment includes the primary ceramic membrane filter plant that aperture is 50nm~200nm and aperture isThe two level ceramic membrane filter equipment of 20nm, the OK a karaoke club collagen solution first pass through primary ceramic membrane filter plant;

    The ceramic membrane bySupporter, transition zone and microporous film layers composition, its membrane tube outside diameter is 30~40mm, and channel diameter is 2.5~6.0mm, port numberIt is 1.016~1.2m to measure as 19~61 holes, membrane tube length;

    (3) cool down plus potassium chloride, cooling push away barThen the plate-type condenser cooling concentration filtrate weighs KCl to 60~65 DEG C according to the 0.15% of concentration filtrate quality,And concentration is made in KCl and is 20% aqueous solution, then be added in concentration filtrate, stir evenly, then use and push away bar machinePush away bar;

    (4) subsequent treatmentThe carragheen after bar will be pushed away to be dehydrated using membrane filter pressing dehydrator, then carry out successively coarse crushing, expansion drying, sterilization,Pneumatic conveying drying, finely divided and sieving, obtain finished product carragheen.
