Description
Technical field:
The present invention relates to pectin slag liquid separation technology field, be specifically related to a kind of efficient pectin slag liquid separating technology.
Background technology:
Pectin is the polymeric carbohydrate that a class forms cellularstructure composition, and pectin molecule main chain is that a galacturonic acid chain coupled together by α-Isosorbide-5-Nitrae glycosidic link is formed, and it is extensively present in green plants.Commercial pectin is white or light beige powder, free from extraneous odour, slightly fruital taste.Pectin derives from plant milk extract, and totally nontoxic is harmless, is generally white to pale yellow powder, is slightly with tart flavour, water-soluble.Food-processing has good gelling, thickening, stable, emulsification and suspension function.Pectin has been widely used in jam, jelly, fruit product, candy, has baked, in nectar, sour milk drink and the Product processing such as Yoghourt and frozen product.
Tradition pectin solid-liquid separation process many employings horizontal spiral centrifuge and plate-and-frame filter press, wherein horizontal spiral centrifuge has the high advantage of level of automation, but horizontal centrifuge facility investment is comparatively large, and the rotary drum life-span is shorter, and running cost is higher.And the residue rate in the pectin solution after centrifugal is still higher, add the cost that subsequent technique removes residue, and after being separated, the water ratio of wet slag is higher, reduces pectin yield.Plate and frame(type)filter press level of automation is lower, is not suitable for use of large-scale production.Bend-band formula vacuum-type drum filter has that facility investment is little, level of automation is high, good filtration effect, do not need essence filter again and the advantage such as stable.
Summary of the invention:
Technical problem to be solved by this invention is to provide the efficient pectin slag liquid separating technology that a kind of equipment investment cost is low, separation efficiency is good.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of efficient pectin slag liquid separating technology, comprises the following steps:
(1) dry pomace is crossed 20-40 mesh sieve and remove cinder and tiny pomace, then in 30-80 DEG C of water, press slag liquor ratio 1:20 cleaning 10-30min;
(2) dropped in reactor by pomace with after pressure filter elimination washing lotion, then add the hot water of 80-100 DEG C, with inorganic acid for adjusting pH between 1-3.5, constant temperature extracts 30-420min;
(3) with bend-band formula vacuum-type drum filter, extracting solution is separated;
(4) filtrate after being separated first regulates pH to be 2.5-4.5 with alkali lye, then adds amylase 30-300ppm;
(5) macropore cation resin or gac is used to carry out deionization to filtrate and decolour;
(6) use MVR vaporizer that the filtrate after decolouring is concentrated 3-5 doubly, wherein water of condensation reheats rear as the hot water use in step (1), and vapor recompression Posterior circle uses;
(7) alcohol adding 2-5 times of 80-95% in concentrated solution carries out pectin precipitation, and uses 1-3 times of 95% alcohol to wash the wet pectin be settled out;
(8) pectin that first will wet pulverize, then dry to water content be 8-10%;
(9) the dry fruit glue obtained is ground to 60-80 order and namely obtains pectin finished product.
In described step (2), using amount of hot water is 15-30 times of pomace tare weight.
Mineral acid in described step (2) is hydrochloric acid, nitric acid or sulfuric acid.
60-120 object filter cloth can be adopted according to the material characteristic of extracting solution in described step (3), the Mierocrystalline cellulose adding 0-4 ‰ is as flocculating aids, and the slag liquid carrying out pectin extracting soln under vacuum tightness-0.02Bar extremely-0.09Bar, rotary drum rotating speed 0.5-5rpm condition is separated.
Alkali lye in described step (4) is sodium hydroxide or ammoniacal liquor.
Amylase in described step (4) is α-amylase.
The gamma value of described pectin finished product is 50%-80%, and galacturonic acid content is 65%-85%.
The invention has the beneficial effects as follows:
(1) the present invention uses bend-band formula vacuum-type drum filter to replace traditional technology, has gathered horizontal spiral centrifuge level of automation height and plate-and-frame filter press good filtration effect, has not needed essence filter again and stable advantage, decreased equipment investment cost;
(2) compare the residue rate of traditional technology 4%-5%, the residue rate after this technique is separated in pectin solution is only 0.5%-2%, effectively reduces the cost that subsequent technique removes residue, improves the work-ing life of follow-up equipment;
(3) after being separated, the water ratio of wet slag is 85%-90%, compares traditional technology 90%-95%, improves separation efficiency, add the yield of pectin;
(4) the present invention is on the basis using bend-band formula vacuum-type drum filter, characteristic for different extracting solution carries out the optimum configurations of bend-band formula vacuum-type drum filter, optimized Separation technique, makes the separation efficiency that the extracting solution of different material characteristic can reach higher.
Embodiment:
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
(1) dry for 100kg pomace is crossed 20 mesh sieves and remove cinder and tiny pomaces, then add 1000kg water clean 20min at 50 DEG C;
(2) with after pressure filter elimination washing lotion, pomace is dropped in reactor, add 80 DEG C of hot water 2100kg, with inorganic acid for adjusting pH to 1.2, constant temperature 240min;
