Description

TECHNICAL FIELD

[0001] The utility model relates to gelatin production technical field, especially relate to a gelatin production's liming aeration device. BACKGROUND

[0002] Gelatin is collagen in animal connective tissue, skin and bone, which is made by partial hydrolysis and denaturation, and has many applications in food, cosmetics, pharmaceutical and biomedical industries. Gelatin is a macromolecular compound formed by 18 kinds of amino acids through peptide bond. The process of traditional alkali method for extracting bone gelatin is divided into two stages: the first stage is hydrolysis, mainly including acid treatment to remove minerals and alkali treatment to hydrolyze and denature collagen; the second stage is water extraction of gelatin. If the first stage of hydrolysis is not sufficient, it will directly affect the extraction results of the second stage, and seriously affect the key indicators of gelatin, such as viscosity and freezing power quality, and the yield of gelatin. If the viscosity and freezing power quality of gelatin decrease, it will lead to the decrease of gelatin price, and the market demand for low viscosity and freezing power gelatin is low, which seriously affects its sales. Therefore, the liming stage is particularly important in the process of traditional alkali method for extracting bone gelatin.

[0003] Gelatin is produced in large quantities in factories, and the production cycle is long, among which the liming process time is the longest. Because it is mass production, whether the liming is sufficient and uniform is the most important factor affecting this process. The existing aeration device is single-point aeration or double-point aeration, which easily leads to uneven aeration of the liming tank, and it is difficult to hydrolyze the bone particles in the dead angle of the liming tank sufficiently, even deteriorate, which affects the quality of gelatin products. SUMMARY

[0004] The utility model aims at solving the problems of insufficient hydrolysis of bone particles, local deterioration and low product quality caused by uneven aeration in the existing gelatin production, and provides a liming aeration device for gelatin production.

[0005] A liming aeration device for gelatin production, comprising a liming tank, an operation platform, a compressed air main pipeline, four compressed air branch pipelines and four groups of compressed air discharge pipelines.

[0006] The operation platform is fixedly arranged on the outer periphery of the upper part of the side wall of the liming tank.

[0007] The bottom surface of the liming tank is inclined.

[0008] The compressed air main pipeline is arranged below the operation platform.

[0009] The four compressed air branch pipelines are laid along the inner side wall of the liming tank, one end of each pipeline penetrates through the operation platform and communicates with the compressed air main pipeline, and the other end of each pipeline communicates with the compressed air discharge pipeline; one stop valve is arranged on each of the four compressed air branch pipelines.

[0010] The four groups of compressed air exhaust pipes are arranged on the bottom surface of the liming pool.

[0011] The angle between the inclined surface of the bottom surface of the liming pool and the horizontal plane is 5°.

[0012] The four groups of compressed air exhaust pipes are arranged in a cross shape on the bottom surface of the liming pool.

[0013] The compressed air exhaust pipes are welded with support frames below.

[0014] The four compressed air branch pipes are communicated with the compressed air exhaust pipes through flanges.

[0015] The working process and working principle of the utility model:

[0016] The utility model adopts four-point aeration mode, which can aeration at four points respectively, simultaneously aeration or diagonal aeration, ensures uniform and sufficient aeration, and reduces the probability of dead angle on the bottom of the liming pool.

[0017] The compressed air exhaust pipes on the bottom of the liming pool are connected with flanges, which is convenient for dismounting and repairing.

[0018] The compressed air branch pipes pass through the operation platform and enter the bottom of the liming pool at the opening above the liming pool, and the valve is installed above the operation platform, which effectively prevents the backflow of the liming pool water into the compressed air pipeline when power failure or compressed air shortage.

[0019] The utility model has the advantages of:

[0020] The utility model has the advantages of simple structure and convenient installation, the compressed air exhaust pipes are connected with flanges, which is convenient for dismounting and repairing, the four-point aeration mode can aeration at four points respectively, simultaneously aeration or diagonal aeration, which ensures uniform and sufficient aeration and reduces the probability of dead angle on the bottom of the liming pool, and solves the problems of insufficient hydrolysis of bone particles, local deterioration and low product quality caused by uneven aeration in the production of gelatin.
