The whole set of alcohol recovery equipment is made of stainless steel, with beautiful appearance, compact and reasonable structure, stable and reliable equipment, which fully meets the requirements of food and medical industries for equipment: the unit consists of five extraction tanks, each of which can select different operation modes for independent extraction or participate in dynamic continuous extraction according to actual production requirements; each extraction tank can complete forward and reverse flow extraction at constant temperature through a circulating pump according to requirements.
According to the process settings, the computer control system can complete the whole process of active countercurrent extraction, ensuring that the content of active ingredients in the extract and the substance in each extraction tank forms a regular concentration gradient at different stages, and countercurrent extraction is carried out according to the regular transfer time and transfer amount; this unit adopts a special separation structure and manufacturing technology to solve the problem of pipeline blockage.
After each countercurrent extraction stage, the extract of one extraction tank is discharged as a product, the slag of one extraction tank is discharged and loaded with new materials, and one extraction tank is added with new solvent to meet the requirements of continuous extraction; the production process of the unit is fully pipelined, and each extraction tank group unit is modularized, and countercurrent extraction units can be added and combined according to process requirements.
The whole system adopts full digital inspection and control technology. The amount of each solvent, heating water temperature, extraction temperature, extraction time, extraction pressure, positive direction stirring time, concentration measurement, etc. can all be automatically controlled; all process indicators of the unit can be debugged, modified and set online; according to needs, it can be configured with manual, on-site control and computer centralized control and other modes; according to needs, alarm, printing, storage and other functions can be added; advanced material production process online analysis system can be optionally equipped with a dedicated material quality control software platform to achieve online quality control of the material countercurrent extraction production process.
High degree of automation, large processing capacity, short extraction time: 30min; small amount of solvent: solid: liquid = 1:8; high extraction rate, compared with the extraction of batches, the content of effective ingredients in the extract is increased by 20%; the extract is of good quality and saves energy.
