Efficient and energy-saving extraction tank

Abstract

The invention relates to an efficient and energy-saving extraction tank. The extraction tank comprises a tank body, a microwave ultrasonic generator and a liquid injection overflow mechanism which arearranged on the wall of the tank, a solid and liquid material separating and converging circulation channel in the tank, and a filter type spiral conveyor below the tank. When the tank is operated, the slurry flat turn circulation flow in the tank is changed into solid and liquid material upper-converting and lower-separating ascending and descending flow, so that microwave ultrasonic wave can perform targeted radiation on a solid material but not on a liquid material, the special structure of the tank allows liquid injection overflow and repeated retraction, and operations of liquid discharging and deslagging can be accomplished at the same time during discharging. The tank is obvious in energy-saving and time-saving effect, low in operation cost and high in efficiency, and provides a novel equipment selection for enterprise production.

Description

technical field [0001] The invention belongs to the field of extracting plant functional components, and in particular relates to a high-efficiency and greatly energy-saving extraction method and device with multiple functional coupling effects. Background technique [0002] Plants are important renewable resources that human society depends on for survival, and are also basic raw materials for industrial production. The extraction and utilization of functional components contained in them is the basic production mode of food, pharmaceutical, health care, biochemical and other industries. At present, traditional extraction methods such as maceration, infiltration, and decoction are still widely used. Although some emerging new technology methods such as microwave method and ultrasonic method have shown broad application prospects and advantages in plant extraction, due to the influence of Restricted by the inherent characteristics of various technologies, most of the new met...

Problems solved by technology

At present, traditional extraction methods such as maceration, infiltration, and decoction are still widely used. Although some emerging new technology methods such as microwave method and ultrasonic method have shown broad application prospects and advantages in plant extraction, due to the influence of Restricted by the inherent characteristics of various technologies, most of the new methods are currently used for small batch processing in laboratories and do not meet the needs of large-scale production. For example, in a certain microwave extraction technology, the magnetron is placed on the container wall, and the microwave emitted by it It can penetrate into the plant tissue, causing the slurry in the container to quickly generate a large amount of heat to break the cell wall, causing the functional components inside the plant tissue to be released and dissolved by the solvent. However, because the microwave can only penetrate into the slurry about 50mm, the energy is attenuated Exhausted, so the scope of action is limited, so the capacity of the appliance is small; another example is another ultrasonic extraction technology, the ultrasonic vibrator is placed at the bottom of the container, and the emitted ultrasonic waves can vibrate the slurry in the container to produce "cavitation" and wall breaking. , so a
