Description

Technical Field

[0001] The invention relates to the fields of biological fermentation and pharmaceutical chemical industry, and in particular to a centrifugal molecular distiller. Background Art

[0002] Molecular distillation is an efficient separation technology that is widely used in the chemical, pharmaceutical, food and other industries. Traditional molecular stills have problems such as low distillation efficiency and easy decomposition of heat-sensitive substances. The centrifugal molecular still is a more ideal molecular still. Its working principle is to send the material to the center of a high-speed rotating turntable and expand it into a thin film on the rotating surface, while heating and evaporating it so that it is concentrated in the condenser on the opposite side. This method can significantly improve the distillation efficiency and reduce the decomposition of heat-sensitive substances. However, the existing centrifugal molecular stills still have room for improvement in terms of material dispersion and heat transfer efficiency. Therefore, there is a need for a new centrifugal molecular still that can further improve the distillation efficiency and reduce the decomposition of heat-sensitive substances. Summary of the Invention

[0004] The centrifugal molecular distiller of the present invention comprises a distiller body, which comprises an outer shell; a rotor disposed within the outer shell; and an annular rib disposed on the rotor. The distiller body is located in the middle of the rotor and is concentric with the rotor. The bottom of the annular rib is provided with a plurality of discharge holes along its circumference.

[0005] Preferably, the inner side of the discharge hole has a curved surface.

[0006] Preferably, the rotor surface is provided with a plurality of cutting edges.

[0007] Preferably, a feed port is provided in the middle portion of the outer shell of the distiller body, and the feed port is correspondingly provided at the center of the rotor.

[0008] Preferably, the cutting edge comprises: multiple rows of cutting edges uniformly distributed along the radial direction of the rotor surface; the angle between each row of cutting edges is thirty degrees to sixty degrees; each of the cutting edges has an arc-shaped blade.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the centrifugal molecular distiller of the present invention includes a distiller body 101, and the distiller body 101 includes a shell 102. A rotor 103 is arranged inside the shell 102, and an annular rib 104 is arranged on the rotor 103. The distiller body 101 is located in the middle of the rotor 103 and is concentric with the rotor 103. The bottom of the annular rib 104 is provided with a plurality of discharge holes 105 along its circumference.

[0018] The inner side of the discharge hole 105 has a curved surface 106. This design facilitates the smooth discharge of the material and reduces the time the material stays in the high temperature zone. The curvature radius of the curved surface 106 can be optimized according to the viscosity and fluidity of the material and can generally be set to 2 mm to 5 mm.

[0019] The rotor 103 is provided with multiple cutting edges 107. These cutting edges 107 are arranged in multiple rows and evenly distributed along the radial direction of the rotor 103. The angle between each row of cutting edges 107 ranges from 30 to 60 degrees, and each cutting edge 107 is curved. The height of the cutting edge 107 can be set to 1 mm to 3 mm, and the curvature of the cutting edge can be one-quarter to one-third of the radius of the rotor 103. This design increases the contact area between the material and the heating surface, improving heat transfer efficiency.

[0020] The middle portion of the housing 102 of the distiller body 101 is provided with a feed port 108, which is located at the center of the rotor 103 to facilitate uniform entry of the material. The diameter of the feed port 108 can be designed according to the flow rate and viscosity of the material, and can generally be set to 10 mm to 30 mm.

[0021] The rotation speed of the rotor 103 can be adjusted according to the characteristics of the material and the desired distillation effect, and can generally be set to 1000 rpm to 3000 rpm. The heating temperature of the housing 102 can also be adjusted according to the boiling point and heat sensitivity of the material, and can generally be set to 50°C to 200°C.

[0022] During use, material enters through feed port 108 and is fully dispersed and brought into contact with the heated surface by centrifugal force and cutting edge 107. The evaporated material is discharged through discharge port 105, achieving a highly efficient molecular distillation process. Unevaporated residue is discharged from the edge of annular rib 104 under the action of centrifugal force.

[0023] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
