Horizontal desorption device

Abstract

The invention discloses a horizontal desorption device, which belongs to the technical field of active material extraction devices. The horizontal desorption device comprises a base, a power transmission mechanism, a revolving drum shaft, a tank, a desorption revolving drum and a medium introduction sleeve, wherein a shaft body of the revolving drum shaft is provided with heating medium inlet andoutlet and condensate inlet and outlet; the tank consists of a tank base and a tank head; and the desorption revolving drum comprises a desorption cylinder body, an isolating sleeve, a condensate extraction tube, a material introduction tube and a revolving drum fixing disk. The horizontal desorption device is characterized in that: the desorption cylinder body has a shape of a cone frustum with a small end and a big end, wherein the small end is fixed to the revolving drum fixing disk; the wall of a port of the big end is provided with a nozzle with a nozzle cavity; the wall of the tank headis connected with a material storage tank on which a material outlet tube is matched; and the centre of the bottom wall of the small end of the desorption cylinder body is fixedly provided with a material distribution cylinder, and the material introduction tube extends in to the material distribution cylinder. The horizontal desorption device can enhance the desorption effect of a liquid medium and improve the desorption efficiency, puts an end to escape of materials, and has an ideal saving effect.

Description

technical field [0001] The invention belongs to the technical field of active substance extraction devices, and in particular relates to a horizontal desorption device, which is suitable for the extraction of active substances in biopharmaceuticals such as traditional Chinese medicines, food additives such as pigments, and vegetable oils. Background technique [0002] Desorption, also known as gas stripping or steam stripping, is a mass transfer separation process that transfers the solute components in the liquid phase to the gas (steam) phase in contact with it. There are hundreds of kinds of mass transfer separation products, such as concentrated delicacy products, such as synthetic cellulose substances, lanolin fatty acid, lanolin alcohol, palm oil, rice bran oil, fish oil, cod liver oil and extracts of the neck roots of natural plants Such as capsicum, lycopene, pyrethrins, lecithin, β-carotene and active ingredients of traditional Chinese medicine and so on.

Problems solved by technology

But this patent application technology still has following shortcoming: the one, easily produce material waste phenomenon, because the discharging of this patent application scheme is to draw out the concentrate by stretching into the concentrate outlet pipe in the concentrate, in the concentrate outlet pipe The pipeline is equipped with a pump. When the pump is working, the concentrate outlet pipe is used to draw the concentrate out. However, during the pumping process, since the concentrate is in contact with the concentrate outlet pipe, it is easy to be mixed with the concentrate. The pipe wall of the material extraction pipe collides to produce liquid foam or foam, which will escape from the vapor recovery port with the vapor, resulting in material waste; second, the introduced raw material to be desorbed does not have an initial distribution effect, because the material enters the The tube introduces the material into the evaporator in the form of a column flow, so it is prone to accumulation effect, which cannot make the material spread to the evaporation surface of the evaporator in a timely and uniform manner, thus prolonging the formation time of the liquid film, which not only affects the desorption efficiency and effect and It wastes energy, and the output per unit time is affected; the third is that the heat transfer loss of the entire spacer is large, which is not compatible with the economical and energy-saving spirit advocated by the whole society.
