Molecule distillation equipment

Abstract

The invention discloses molecule distillation equipment which comprises a molecule distillation equipment body and a vacuum tube, wherein a material distribution device is arranged at the upper end of the molecule distillation equipment body. The molecule distillation equipment is characterized in that the molecule distillation equipment body is a semi-cylindrical or semi-elliptical hollow column body; a rectangular side plane of the hollow column body is a material heating surface plate. The molecule distillation equipment has the beneficial effects that a good sealing effect can be achieved, the equipment manufacturing, operation and maintenance costs are relatively low, no stirring device is needed, a film can be automatically formed by using the material from top to bottom along an inclined surface, production continuity can be achieved, the time that the material passes through a heating surface is short, the product quality is good, power resources can be saved, the thermal energy utilization rate is high, the production cost is low, and the like; if the molecule distillation equipment is popularized and applied in related industries, related industrial lifting equipment and lifting process techniques can be powerfully ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to equipment for distillation and purification of edible oil products, oleochemical products, other various chemical products, and plant extracts and separation of different components, in particular to molecular distillation equipment. Background technique [0002] Molecular distillation, also known as short-path distillation, is a relatively new liquid-liquid separation technology that has not been widely used in industrial production. Its application can solve a large number of problems that cannot be solved by conventional distillation technology. Compared with conventional distillation technology, it has the following advantages: 1. Ordinary distillation operates at the boiling point, while molecular distillation can be separated at any temperature as long as there is a sufficient temperature difference between the hot and cold surfaces. Therefore, the operating temp...

2. Ordinary distillation has bubbling and boiling phenomena, while molecular distillation is free evaporation on the surface of the liquid film, the vacuum degree is very good, the working pressure is very low, generally in the order of 0.1-1Pa, and the heating time is very short, generally only ten seconds to a few minutes

However, there are certain limitations in this technique:

[0004] 1. The design body of the equipment has an oil cavity and a heat transfer oil cavity. The oil cavity is negative pressure, and the heat transfer oil cavity is positive pressure. If it goes into the oil cavity, the consequences will be unimaginable. At the same time, because the heating surface is not round and evenly stressed, it is also easily deformed, and the distillation and evaporation effect is not good.

[0005] 2. The oil chamber of this technology has chamber A on the top and chamber B below, which is equivalent to an oil storage tank with an oil storage function on the top and an oil storage tank with an oil storage function on the bottom. Such a main body The equipment is not scientific
