Problems solved by technology

2. Ordinary distillation has bubbling and boiling phenomena, while molecular distillation is free evaporation on the surface of the liquid film, and the operating pressure is very low. Generally, it is on the order of 0.1-1Pa, and the heating time is very short, generally only ten seconds to several minutes.
3. Evaporation and condensation in ordinary distillation are reversible processes, and there is a dynamic phase equilibrium between the liquid phase and the gas phase, while in the molecular distillation process, the molecules escaping from the heating surface fly directly to the condensation surface, and theoretically do not return to the heating surface Possibility, so molecular distillation

Abstract

The invention discloses an internal heating type molecular distillation equipment, which comprises an external sealing device and an internal heater. The sealing body of the external sealing device is a hollow cylindrical or barrel-shaped structure with a bottom end, and the sealing body is provided with a top end. Head, the top end of the head is provided with a material inlet pipe, and the inner heater is in the shape of a circular table or a cone or a cylindrical structure. The heater is installed at the inner bottom of the sealing body or becomes a part of the bottom of the sealing body; the heating surface of the outer wall of the heater There are multiple material distributors; the vacuum tube is set on the sealed body, and the space between the inside of the sealed body and the heater is connected to the vacuum tube; the outlet for low boiling point materials is located below the inner wall of the sealed body, and the outlet for high boiling point materials is at the lower edge of the heater. In the invention, the material automatically forms a thin film along the slope from top to bottom, the production is continuous, the time for the material to pass through the heating surface is short, the product quality is good, the heat energy utilization rate is high, and the production cost is low.

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 an internal heating molecular distillation equipment. technical background [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,...
