Small scale extraction and concentration equipmentPut the material into the extraction tank, add 5-10 times the solvent such as purified water, ethanol, etc. according to the required liquid in the extraction process, first open the extraction steam valve, steam for about 1 hour, turn on the vacuum equipment to draw the liquid into the evaporator of the heater, open the secondary steam valve of the * heater, heat and evaporate continuously for 3-4 hours, then close the extraction equipment and the secondary steam valve of the * heater, and open the steam valve of the second heater for paste collection. The spray gun of the experimental spray dryer is equipped with a stainless steel needle that can automatically dredge and its working frequency can be adjusted. When the nozzle is blocked, the needle will automatically clear the blockage to ensure the continuous and normal operation of the experiment.

Small scale extraction and concentration equipmentThe advantage of the combined application device for effective ingredient extraction and concentration is that it integrates extraction and concentration.Small scale extraction and concentration equipmentAdopting fully enclosed continuous cycle extraction and concentration, steam is generated during the hot extraction process and can be recovered while refluxing through condensation. When the condensate refluxes, it flows deep into the material, allowing the liquid to fully contact and play a dynamic extraction role, while reducing the amount of solvent input and extraction time, improving production efficiency and product yield.Small scale extraction and concentration equipmentThe solution inside continuously enters the bottom of the circulating heater through a filter and gradually undergoes concentration. The whole process of spray drying experiment can be seen, which is convenient for controlling the experiment process and finding and adjusting problems in time. All glass components are easy to disassemble and clean. Equipped with an imported oil-free air compressor, the particle size of the powder sprayed follows a normal distribution, with good fluidity and very low noise, less than 60db, which meets the national laboratory noise standards.
