The invention is characterized in that soaking skin, decolorizing, adding ash, adding acid and cleaning are carried out as the following procedures: (1) Skin soaking: mixing water, skin, lime, chlorine dioxide and sodium chloride are according to the proportion of 100:30-60: 5-20:15-30:5-15, stirring sufficiently and standing still for 5-10 days. (2) Cleaning: inputting water and soaked skin into a pool are according to the proportion of 100:50-90, stirring and cleaning for 16-48 hours. (3) Adding acid: inputting water, cleaned skin and sulfuric acid with concentration of 60 percent into a pool with the ratio of 100:50-90:8-20 and soaking for 12-24 hours. When acid-base balance is realized, discharging water solution and cleaning with clean water.

Description

Production method of gelatin

Technical field

The present invention relates to a kind of production method of gelatin, the method that the tankage in especially producing with onal such as leather are produced gelatin.

Background technology

Relatively commonly used at present and sophisticated manufacturing of gelatin method comprises following process: 1, soak skin: in the pond with water temperature 5-25 ℃, by water and 100: 50 ratio of skin immersion 72 hours, every stirring in 10 hours 1 hour, reach the effect that the skin tissue soaks into, swells; 2, decolouring: in the pond, water, dioxide peroxide, skin were soaked 48 hours in 100: 5: 50 ratio, stirred 1 hour, reach decolouring fully, as decolour not exclusively, repeat this program every 5 hours; 3, add ash: in the pond water, unslaked lime, skin are soaked in 100: 10: 50 ratio, per 72 hours is one-period, needs 3-5 cycle, reaches acid base equilibrium; 4, add acid: in the pond water, acid, skin are soaked in 100: 5: 50 ratio, per 120 hours is one-period, needs 3-5 cycle, reaches acid base equilibrium; 5, clean: through water logging bubble, repeatedly cleaning, per 48 hours is one-period, needs 2-3 cycle, thoroughly removes intracutaneous impurity and poisonous, objectionable impurities in the pond; 6, heating plastic emitting: the skin that will clean is in water and 100: 70 ratio of the skin saucepan of packing into, the plastic emitting of heating, according to circumstances, plastic emitting road number is generally the 2-4 road, as, going out the first road glue more than 65 ℃, viscosity is the 12-13 degree, go out the second road glue more than 75 ℃, viscosity is the 10-12 degree, goes out the 3rd road glue more than 85 ℃, and viscosity is the 8-10 degree, go out extreme trace glue more than 95 ℃, viscosity is the 4-6 degree; 7, evaporation: the liquid glue that comes out in the saucepan is little because of viscosity, and the moisture content height need fully evaporate moisture in triple-effect evaporator or other utensil, till viscosity is when 12 degree are above; 8, drip glue: glue drips on the freezing roller, with specific equipment adhesive tape is cut into little adhesive tape, so that processing, transportation and storage; 9, oven dry: by the moisture in the drying plant oven dry adhesive tape; 10, packing: by certain specification and requirement packing.The shortcoming of this production method is: 1, the production cycle long, efficiency is low, the production process of extracting gelatin generally needs the trimestral time, technological process is loaded down with trivial details simultaneously, the labour intensity height; 2, water consumption is big, and the water consumption of producing 1 ton of gelatin reaches about 1100 tons.

Summary of the invention

The purpose of this invention is to provide a kind of new production method of gelatin, this method can effectively shorten the production cycle of gelatin, reduces the consumption of water.

The objective of the invention is to realize in the following manner.

Production method of gelatin, comprise and soak skin, decolour, add ash, add acid, cleaning, heating plastic emitting, evaporation, drip glue, oven dry, packing etc., wherein soak skin, decolour, add ash, add acid and cleaning realizes by following operation: (1) boils in a covered pot over a slow fire skin: Jiang Shui, skin, unslaked lime, dioxide peroxide, sodium-chlor by 100: the mixed of 30-60: 5-20: 15-30: 5-15 also fully stirs, and places 5-10 days; (2) clean: with water and the skin of boiling in a covered pot over a slow fire in 100: the ratio of 50-90 is put into the pond, and stirring and washing got final product through 16-48 hour; (3) add acid: with water, the skin that cleaned and concentration be 60% sulfuric acid by 100: 50-90: 8-20 puts into the pond and soaks, and soak time is 12-24 hour, makes to reach acid base equilibrium, and the aqueous solution is bled off, and cleans with clear water then to get final product.

Production method of gelatin provided by the invention has following advantage: 1, the production cycle of gelatin obviously shortens, and the shortest time can reach about two weeks, simultaneously, had reduced processing step, had reduced labour intensity; Major cause is to have replaced maximum the soaking skin, decolour, add ash, add acid and matting of original time spent with new stewing skin, cleaning and acid adding process, soaks into to swell effectively, and the time spent of new stewing skin, cleaning and acid adding process obviously reduces.2, water consumption obviously reduces, and produces the water consumption of 1 ton of gelatin and has only about 200 tons.3, with this method original production technique is put in order after, plastic emitting road number also has minimizing, can go out glue twice in saucepan, quality also is higher than original method.
