Continuous extracting method of microwave

Abstract

The invention mainly relates to a microwave continuous extraction process, belonging to pharmacy, food and chemical industry so on, which extracts material in microwave and evaporates and concentrates it in single-effect external cycle. It comprises a microwave extraction equipment (1), a collector for air foam (2) for collecting the foam generated in heating process to material, a filter (3) at the bottom of microwave extraction equipment (1), a concentration heater (5) connected with the filter (3) through a transporting pipe (12), a concentration and evaporation room (4) for heated extraction liquid by pressure and concentration differences, a cooling system (6), an oil-water separator (7) for cooling the gaseous available component and collecting aromatic stem oil material, a liquid storage tank (8), a vacuum pumping system (9) and a blow-off valve (10) set on the liquid storage tank (8). The whole extraction and concentration process is continuous and at the same time so that producing time, energy source and manpower are saved greatly. It is provided with high extraction rate, low using cost and it is the most advanced extraction and concentration process. It can extract continuously and also extract in cold-hot reflux.

Description

Technical field: [0001] The invention mainly relates to a microwave continuous extraction technological process for extracting and concentrating materials in the fields of pharmacy, food, chemical industry and the like. Background technique: [0002] Extraction and concentration are basic processes in the pharmaceutical, food, chemical, and industries, but so far, all manufacturers of extraction and concentration equipment provide equipment that regards extraction and concentration as two independent processes and devices, and In order to achieve separation and efficient recovery, each equipment is equipped with a cooling system, which not only wastes energy, solution and manpower, but also the most important thing is that the heat source of the heating equipment used in the extraction device is steam or heating oil, resulting in a production cycle. Long, low production efficiency, high cost. Invention content: [0003] Aiming at the defects of the above-mentioned equipme...
