Description

Technical Field

[0001] The utility model relates to the technical field of material dispersing devices, in particular to an emulsifying and homogenizing device for lipase. Background Art

[0002] Lipase is a triacylglycerol acyl hydrolase, which catalyzes the hydrolysis of natural substrate oils and fats to produce fatty acids, glycerol and mono- or di-glycerides. The basic components of lipase are only amino acids, usually with only one polypeptide chain. Its catalytic activity is determined only by its protein structure. With the continuous development and changes in various aspects of social economy, green technology has gradually become an important driving point for chemical production. Lipase is relatively green and environmentally friendly in the process of chemical synthesis, making it more widely used. It plays a very important role in various fields such as chemical industry and medicine. Lipase has become one of the important industrial enzymes for the synthesis of chemical products.

[0003] Traditional lipase immobilization technology is mainly used to improve the stability of lipase in non-aqueous environments. Traditional immobilization methods include physical adsorption, embedding, cross-linking and covalent bonding. In industrial applications, organic solvents or surfactants are often added to solubilize substrates, but for food processing, toxic organic solvents and surfactants should be avoided to solubilize substrates. Using the oil-water interface to activate lipase activity is a common method, but the traditional oil-water interface area is small, which limits the catalytic rate of lipase on the oil phase. In order to overcome this difficulty, surfactants or particles are added to form water-in-oil (O / W) or oil-in-water (W / O) emulsions to increase the oil-water interface area.

[0004] The existing lipase forming water-in-oil or oil-in-water emulsion process is mostly to promote the emulsification process by stirring with a homogenizer. At the same time, the homogenizer can also be used to disperse lipase and synthetic raw materials. Homogenizers can be roughly divided into high-pressure homogenizers and high-shear homogenizers. High-pressure homogenizers require materials to pass through a narrow channel, which is easy to clog for lipase emulsification. Therefore, high-shear homogenizers are often used for dispersion and emulsification, and the emulsification dispersion degree is often not high.

[0005] For example, a bio-enzyme homogenizer proposed in the patent with publication number CN219879760U, under the action of the circulation pipe and the reflux pipe, the bio-enzyme is lifted away to the feed pipe again, and then enters the homogenization tank again through the action of the feed pipe, so that the bio-enzyme raw material can be stirred, sheared and homogenized again, and the material is fully emulsified and dispersed after multiple homogenization and mixing. However, the device requires an external additional lifting pump and lifting pipeline to lift the raw material again and homogenize it multiple times, which requires additional equipment and operations, and the newly added lifting pipeline is not easy to clean and is easy to cause raw material blockage. Utility Model Content

[0006] The utility model aims to provide a lipase emulsifying homogenizing device to solve the technical problems that the existing lipase homogenizing device homogenizes materials multiple times through a lifting pipeline, and the viscous materials are easy to block the lifting pipeline and it is difficult to clean.

[0007] The embodiments of the present invention are implemented by the following technical solutions:

[0008] A lipase emulsifying and homogenizing device comprises a rotating shaft and a homogenizing disk rotatably arranged on the rotating shaft for shearing and emulsifying raw materials. The rotating shaft is also provided with a feeding cylinder for collecting materials and conveying the materials downward to the homogenizing disk and a lifting port for outputting the sheared and emulsified materials upward.

[0009] Preferably, the homogenizing disk comprises a stator ring for fixedly shearing the material and a rotor ring axially connected to the rotating shaft for rotationally shearing the material.

[0010] Preferably, the rotor ring and the stator ring are provided with a through opening for passing the material and a slit for squeezing and shearing the material during relative rotation.

[0011] Preferably, a first cutter axially connected to the rotating shaft for primary cutting of materials is provided inside the rotor ring, and a second cutter for secondary cutting of materials is provided outside the stator ring.

[0012] Preferably, an annular collecting trough for collecting sheared and cut materials is provided on the outer side of the second cutter, and the collecting trough is connected to the lifting port.

[0013] Preferably, the homogenizing disk further comprises a feed port for inputting materials and a discharge port for outputting materials, the feed port is connected to the feed barrel and the inner side of the rotor ring, and the discharge port is connected to the lifting port and the collecting trough.

[0014] Preferably, the homogenizing disk further comprises a connecting frame axially connected to the rotating shaft, and the connecting frame connects the rotor ring and the second cutter.

[0015] Preferably, the feeding barrel is provided with a spiral blade axially connected to the rotating shaft for conveying the material downward.

[0016] By adopting the technical scheme, the material can be fed through the feeding barrel connected to the homogenizing disk on the same rotating shaft. The spiral blades in the feeding barrel rotate with the rotating shaft to absorb the material above and near the feeding barrel and then push it into the feeding port. The material is fully homogenized and emulsified through the shearing and cutting of the first cutter, stator ring, rotor ring and second cutter of the homogenizing disk. The material is collected through the collecting trough and sent to the discharge port, and then transported upward through the lifting port. The lifting port and the feeding barrel cooperate to form a circulating flow of the material inside and outside the batching container. The material can be automatically homogenized and emulsified multiple times by rotating the same rotating shaft, ensuring that the material is more fully homogenized and emulsified; and no additional lifting pipeline is added, so no additional lifting power is required.

[0017] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0018] 1. The utility model forms a circulation flow of materials inside and outside the batching container through the cooperation of the lifting port and the feeding barrel.
