A gelatin extraction device for gelatin production

Abstract

The invention discloses a gelatin extraction device for gelatin production. The device includes a gelatin extraction body. A feeding port, an exhaust port, and an water inlet are arranged on the upper surface of the gelatin extraction body, and a water outlet and a deslagging port are arranged on the lower surface of the gelatin extraction body. The bottom of the inner chamber of the gelatin extraction body is provided with multiple heating tubes, and each heating tube is provided with an independent steam connector. The bottom of the inner chamber of the gelatin extraction body is also provided with an air lift. According to the invention, multiple heating tubes and the air lift are provided at the bottom of the inner chamber of the gelatin extraction body, so the bottom of the inner chamber of the gelatin extraction body is guaranteed to have a uniform heating; compressed air is employed to stir liquid materials in the gelatin extraction body, which allow the liquid materials to produce relatively intense convection, so that the temperature uniformity of the liquid materials of different parts is achieved, and a temperature difference of less than two DEG C is guaranteed; and the gelatin extraction body has a volume range of from 10m3 to 120m3, so the gelatin extraction device also has the advantage of large capacity.

Description

technical field [0001] The invention relates to the technical field of gelatin production, in particular to a gelatin production and extraction equipment. Background technique [0002] Gelatin is a protein extracted from the connective tissue of animal skin or bone by hydrolysis and is a product of collagen degradation. Commercial gelatin is divided into medicinal gelatin and edible gelatin, and is divided into skin gelatin and bone gelatin according to the source of raw materials. The production process of gelatin is as follows: raw materials are crushed, pickled, limed, soaked in alkali, neutralized and washed, boiled, filtered, evaporated, dried, crushed, and packaged. Among them, the gelatinization process is a process in which collagen is converted into gelatin by heating and hydrolyzing in hot water after acid-base degradation treatment. [0003] As we all know, the physical properties of gelatin and product quality are related to the heating temperature and heating ...

Problems solved by technology

[0004] At present, in the gelatin extraction industry, most of the traditional heating devices use coil heating. In order to ensure that the glue is fully heated, it is necessary to ensure full contact between the glue and the coil. Therefore, the traditional coil is often bent into various The same shape, but these coils have a common feature that there is only one inlet and one outlet. Generally, the temperature at the inlet end of the coil is relatively high, so the temperature of the glue near the inlet end of the coil rises faster, but The temperature at the outlet end of the coil is relatively low, so the temperature of the glue near the outlet of the coil rises relatively slowly. When the volume of the glue lifting equipment is large, it is often found that the temperature of the glue near the inlet of the coil is much higher than that of the coil. The temperature of the glue solution near the outlet end, when the temperature of the glue solution near the inlet end of the coil differs from the temperature of the glue solution near the outlet end of the coil by 5°C, the purity of the extracted gelatin at this time is relatively low, and it was found in the actual production process , when the volume of the rubber extraction equipment reaches 10m 3 When the above is above, the difference between the highest temperature and the lowest temperature of the glue inside the glue extraction equipment sometimes reaches 15°C or even greater; The phenomenon of layering and backlog in the pot is easy to cause the glue to have no fluidity, thus hindering the convection of the liquid temperature, so that the temperature of the heat source point cannot be diffused, and the result will inevitably lead to the failure of the separation of the glue and reduce the yield of high-quality gelatin
