Preprocessing and preparation:
Pretreatment of raw materials is key to ensure that the particle size, humidity and other parameters of the raw materials meet the extraction requirements to improve extraction efficiency.
Check whether the equipment is intact, especially components such as mixers, valves and pipes, to ensure there are no leaks or blockages.
According to the extraction requirements, prepare the required solvents and ensure that their quality and purity meet the standards.
Operation process:
According to the operating procedures, add the pretreated raw materials and solvent into the mixer-settler. Pay attention to controlling the feeding speed and feeding sequence to avoid excessive foam or vortex.
Start the stirrer to thoroughly mix the raw materials and solvent. The stirring speed and time should be adjusted according to the nature of the raw materials and extraction requirements to achieve the best mixing effect.
During the stirring process, closely observe the state and changes of the mixed liquid, such as color, turbidity, etc., in order to detect and deal with abnormal situations in time.
When mixing reaches a certain level, turn off the stirrer and let the mixture sit for a while to allow the substances to separate in the solvent. The length of standing time depends on the nature of the raw materials and extraction requirements.
Separation and collection:
When the mixed liquid is separated into layers, the liquids in different layers are led out separately through valves and pipes. Pay attention to controlling the extraction speed and flow rate to avoid mixing between liquids.
The extracted liquid is collected and processed, such as filtration, concentration, etc., to obtain the required extract.
Cleaning and maintenance:
After the operation is completed, clean the equipment in time to remove residues and dirt to avoid affecting the next operation.
Carry out regular maintenance and upkeep on equipment, check the operation of each component, and discover and deal with potential problems in a timely manner.
Safety and environmental protection:
During operation, strictly abide by safe operating procedures, wear protective equipment, and avoid splashing and inhalation of solvents.
Pay attention to the storage and handling of solvents to prevent leakage and environmental pollution. Waste solvents and extracts should be properly disposed of in accordance with environmental protection requirements.
