Problems solved by technology
[0003] The gelatin extracting equipment for the traditional alkaline method is made of round or square stainless steel, with grate plates installed on the bottom side, and compressed air is used to stir or pump the gel in the process of extracting gelatin. Each pot of material needs to be extracted four to five times. Glue, the rubber extraction equipment uses the traditional rubber extraction process for a period of up to 60 days, and the material leakage is serious during the glue extraction process. After the glue is lifted, the slag is labor-consuming and time-consuming, and the cleaning and disinfection of the glue pot is even more inconvenient.
This traditional rubber extraction equipment has not been improved for many years
[0004] Moreover, the method of extracting gelatin prepared by the traditional alkaline method determines that several main indicators of gelatin products are unstable and fluctuate greatly. In particular, the viscosity is between 3.0~5.0mPa.s, and the transmittance at 450nm is between 65%~88%. Between, the freezing strength is between 100~240g
[0005] It should also be pointed out that the aggregate consumption per ton of gelatin is currently about 7 tons, which is high cost

Example Embodiment
[0024] The technical scheme of the present invention will be described in detail below with reference to the drawings and specific embodiments.
[0025] Such as figure 1 As shown, the gelatin extraction process for the industrial production of gelatin used in the production of capsules by the biological enzyme method, after the bone meal is put into the gelatin extraction pot, add water to raise the temperature to 40-70°C (the ratio of water to material to liquid is 1:3.5), and the pH value is adjusted to 2-11 , Add enzyme for 1-10 hours to extract the gum solution, then adjust the PH value to 2-10, after 1-3 hours, adjust the pH value of the gum solution to 5.5-6.5, and then coarsely filter the gelatin liquid and solid residue , Fine filtration, concentration, sterilization, drying and crushing to obtain gelatin products.

The invention provides a gelatin extraction process for preparing gelatin through an enzyme method. The gelatin extraction process comprises: 1) adding bone powder into a gelatin extraction device, adding water, and heating to a temperature of 40-70 DEG C; 2) adjusting the PH value to 2-11, adding enzyme, extracting a gelatin liquid after 1-10 h, adjusting the PH value to 2-10, maintaining for 1-3h, and adjusting the PH value of the gelatin liquid to 5.5-6.5; and 3) carrying out filtration separation on the gelatin liquid and the solid residue. The invention further provides a gelatin extraction apparatus for preparing gelatin through an enzyme method, wherein the apparatus is provided with a material inlet, a gelatin outlet and a stirring device, the stirring device comprises a stirringshaft and paddle blades, and the grate or the similar structure of the gelatin extraction apparatus in the traditional gelatin process is not arranged in the apparatus of the present invention. Compared to the traditional alkali gelatin process and the traditional alkali gelatin apparatus, the gelatin extraction process and the gelatin extraction apparatus of the present invention have advantagesof shortened production period, substantially improved efficiency, and improved gelatin quality stability.
