Thermal reflux extraction concentrator
Detailed description
Works
will invest herbs extraction tank, add herbs 5-8 times a solvent (water,
ethanol, acetone, etc., according to process requirements). Open the
extraction tank through the steam valve and jacket, so that the extract
is heated to boiling 20 to 30 minutes later, with a suction tube to
extract 1/3 into the concentrator. Close the extraction tank through and
jacket steam, open the heater valve to concentrate the liquid
material. Concentration generated secondary steam, through the
evaporator riser tube into the extraction tank for the extraction of
heat and solution to maintain the extraction tank boiling.
The secondary steam continues to rise, the condenser condensing into a
hot condensate, back to the extraction tank for new solvents added to
the drug surface, the new solvent from top to bottom through the
medicine layer to the bottom of the extraction tank, the soluble active
ingredients dissolved In a solvent. The extracted liquid is drawn into
the concentrator through the filter tube, and the secondary vapor
produced by the concentration is sent to the extraction tank as the heat
source and the new solvent. The new solvent is recirculated and
reclaimed so that the solute density in the medicinal material keeps
with the solute density The concentrated solution is continuously
transferred to the concentrator and the condensed secondary steam is
transferred to the cooler, and the concentration is continued until the
ointment having the specific gravity (1.2 to 1.34) is concentrated and
released for use . Extraction residue can be put into the tank for the
next batch, slag from the slag gate drain, if extracted with organic
solvents, the first increase the amount of water, open and jacket steam,
recovery of solvent, the Slag discharge row.
Features
1, cream collection rate increased to 15% compared with 10 multi-purpose
tanks, ointments containing the active ingredient higher than 1
times. As the extraction process, the hot solvent added to the drug
surface continuously, from top to bottom through the drug layer at high
speed, dissolve the solute in the medicinal herbs, solute content in the
solvent and solvent content to maintain a high gradient, herbs Soluble
high-speed dissolution, until completely dissolved, the effective
component extraction rate is high, concentrated in a set of sealing
equipment to complete, loss of small, high conversion rate, the high
rate of cream, ointment high active ingredient content.
2, due to high-speed dissolution of solutes, extraction time is short,
concentrated and extraction simultaneously, so the medicine to the
concentrated ointment only 7 to 8 hours, equipment utilization.
3, a single device, an area of small, high utilization of equipment, investment province.
4, the extraction of only one solvent, in a set of sealing equipment
recycling, solvent residue in the solvent is basically recovered, the
amount of solvent than multi-function extraction tank 30% less,
consumption rate can be reduced by 50 to 70%, which is With the organic
solvent extraction, purification of active ingredients in traditional
Chinese medicine to provide a more advanced process methods.
5, due to the concentration of secondary steam for the extraction of
heat, extracted into the concentrator with the concentration of the
extract and the temperature can save steam, the operation easier,
reducing the operator.
Features
The equipment is suitable for herbal plants, herbs, animals, and food
additives. The use of water, ethanol, methanol, acetone, such as the
extraction and recovery and concentration of organic solvents.
