Abstract
The invention relates to a mint leaf extraction technology, and belongs to the field of mint oil extraction methods. The mint leaf extraction technology comprises the following steps of 1, sorting impurities, and removing moth and mildewing parts; 2, opening a top cover of a distilling pot, filling water into the pot to the part 20cm away from a steaming pad, uniformly throwing the raw mint leaves into the pot, pressing the surroundings of the pot, enabling the top part to form a round head shape, covering the top cover of the distilling pot, and filling water into a water seal groove at the connecting part; 3, opening a steam intake valve, filling steam, enabling the water in the pot to boil as quick as possible, controlling the steam valve when a large amount of oil and water mixing solution flows out of an oil outlet of a condenser, controlling the steam pressure to 0.5-0.6MPa, and maintaining the stable oil flowing-out rate; 4, distilling for 1.5-2h, finishing until the flowing liquid is clear and the oil bloom is minimum, and closing the steam intake valve; 5, fetching the mint oil out of an oil and water separator.
Description
Technical field
The present invention relates to a kind of mentha leave extraction process, belong to Mentholum field.
Background technology
It is all first to carry out mentha leave drying pulverization process that mentha leave is extracted Oleum menthae by prior art, and when processing, Oleum menthae also very easily loses, and production technology is also loaded down with trivial details.
Summary of the invention
The technical problem to be solved is in that: provide a kind of and mentha leave directly carries out steam distillation, reduce processing step, adopt B-grade condensation operation to improve the productivity of Oleum menthae, increase the mentha leave extraction process of production efficiency.
The technical problem to be solved takes techniques below scheme to realize:
A kind of mentha leave extraction process, comprises the steps:
Step 1: pick except the impurity in mentha leave, rejecting is damaged by worms, part of going mouldy;
Step 2: open boiler top cover, adds water in pot from steaming pad 20 centimeters, is put into uniformly in pot by raw material mentha leave, and surrounding compresses, and top is globular model, then covers boiler top cover, topped up with water in the water sealed tank of junction;
Step 3: open steam inlet valve, pass into steam, first-stage condenser and secondary condenser is opened when water temperature reaches 70 degree time, after in pot, water seethes with excitement as early as possible, distillation Stress control is between 0.5MPa��0.6MPa, when first-stage condenser oil-out has most of oil water mixed liquid to flow out, control steam valve, keep fuel-displaced flow velocity steady, distill 1.5��2 hours, clarify with effluent, be that distillation terminates during without obvious oil bloom, steam off air intake valve, after the condenser of two-stage, distillate temperature controls between 35 to 40 degree;
Step 4: use cooler again to cool down the oil water mixture flowed out in secondary condenser, temperature controls between 20 to 25 degree,
Step 5: in still-process, Oleum menthae isolated by continuous oil water separator.
As preferred embodiment, the described various piece first checked before step 2 and clean boiler equipment, slowly opening steam inlet valve, steam pressure keeps 0.2MPa��0.3MPa to be not added with the steaming of raw material sky to only adding water in boiler, and 0.5 hours removes the abnormal smells from the patient of remaining.
The invention has the beneficial effects as follows: directly mentha leave is carried out steam distillation, reduces and mentha leave is dried pulverizing process, and reduce the loss of Oleum menthae in the process.
Detailed description of the invention
In order to the technological means of the present invention, creation characteristic, reach purpose and effect and be easy to understand, the present invention is expanded on further.
A kind of mentha leave extraction process, comprises the steps:
Step 1: pick except the impurity in mentha leave, rejecting is damaged by worms, part of going mouldy;
Step 2: open boiler top cover, adds water in pot from steaming pad 20 centimeters, is put into uniformly in pot by raw material mentha leave, and surrounding compresses, and top is globular model, then covers boiler top cover, topped up with water in the water sealed tank of junction;
Step 3: open steam inlet valve, pass into steam, first-stage condenser and secondary condenser is opened when water temperature reaches 70 degree time, after in pot, water seethes with excitement as early as possible, distillation Stress control is between 0.5MPa��0.6MPa, when first-stage condenser oil-out has most of oil water mixed liquid to flow out, control steam valve, keep fuel-displaced flow velocity steady, distill 1.5��2 hours, clarify with effluent, be that distillation terminates during without obvious oil bloom, steam off air intake valve, after the condenser of two-stage, distillate temperature controls between 35 to 40 degree;
Step 4: use cooler again to cool down the oil water mixture flowed out in secondary condenser, temperature controls between 20 to 25 degree,
Step 5: in still-process, Oleum menthae isolated by continuous oil water separator.
Further, the described various piece first checked before step 2 and clean boiler equipment, slowly opening steam inlet valve, steam pressure keeps 0.2MPa��0.3MPa to be not added with the steaming of raw material sky to only adding water in boiler, and 0.5 hours removes the abnormal smells from the patient of remaining.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described. Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, and without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention. Claimed scope is defined by appending claims and equivalent thereof.
