Description
Technical Field
The invention relates to the technical field of bamboo deep processing, in particular to a method for extracting fresh bamboo juice by utilizing ultrasonic waves.
Background
Fresh bamboo juice as a traditional Chinese medicine has medicinal value recorded as early as Ben Cao gang mu, and has the efficacies of sweet smell, no toxicity, treatment of sudden stroke, wind arthralgia, chest and middle-large blood, relieving vexation, quenching thirst and the like. And is recorded in the first volume of traditional Chinese medicinal materials with pharmaceutical standards issued by the 1992 ministry. Modern researches show that fresh bamboo and thunberg contains more than 10 amino acids, wherein tyrosine accounts for 55-68% of the total content, and the fresh bamboo and thunberg contains organic compound components such as guaiacol, gluconic acid, salicylic acid, phenol, germanium, silicon and the like; has therapeutic effect on cough and bronchitis; with the development of modern science and technology, fresh bamboo and Zhejiang are widely applied to the aspects of medicines, food beverages, health-care products and the like.
The fresh bamboo juice stock solution is mainly extracted from bamboo, but in the prior art, when the fresh bamboo juice is extracted, in order to improve the extraction rate of the fresh bamboo juice, the bamboo needs to be cut into small blocks or even fine powder. The method can improve the extraction rate of the fresh bamboo juice by treating the bamboos, but greatly reduces the utilization value of the bamboo blocks and the bamboo powder which are remained after the fresh bamboo juice is extracted, and can only be treated as waste materials generally, thereby greatly wasting bamboo resources.
Disclosure of Invention
The invention aims to provide a method for extracting fresh bamboo juice by using ultrasonic waves aiming at the technical defects of the prior art, so as to solve the technical problem that slag obtained by extracting the fresh bamboo juice by using a conventional method is difficult to recycle.
Another technical problem to be solved by the invention is how to extract fresh bamboo juice simultaneously in the process of processing bamboo products.
The invention aims to solve the technical problem of how to further improve the extraction rate of the fresh bamboo juice.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
a method for extracting fresh bamboo juice by ultrasonic comprises the following steps:
a. slicing the bamboo through a chipping machine, and screening and selecting bamboo chips with the length of 6-45 mm;
b. putting the bamboo chips into a cooking pot, introducing high-temperature steam, heating the cooking pot to 180 ℃ for 5-25min to soften the bamboo chips, and taking the softened bamboo chips out of the cooking pot, discharging the steam, and collecting condensate through a condenser;
c. b, putting the bamboo chips treated in the step b into a micro-airflow and ultrasonic extraction device (which needs to be quickly put into the device) for extraction, and collecting an extract;
d. c, grinding the bamboo slag treated and filtered in the step c into bamboo pulp by a high-concentration mill;
e. pressing the bamboo pulp out of the liquid through a filter press, simultaneously injecting water for cleaning, and collecting the liquid;
f. collecting the liquid obtained in the steps b, c and e into a filtrate collecting tank, and filtering to remove solid impurities in the liquid to obtain fresh bamboo juice stock solution;
g. sterilizing the obtained succus Bambusae stock solution in autoclave, and flash evaporating to obtain succus Bambusae product.
Preferably, the bamboo chips sliced and screened in the step a are soaked in clear water for 15-30min, and then the step b is executed.
Preferably, the bamboo chips softened in the step c are treated in a micro-airflow ultrasonic extraction device for 10-20 min.
Preferably, in the step d, the beating degree of the bamboo pulp after high-concentration grinding treatment is 20-30 DEG SR. Wherein, the clearance of the high-concentration grinding disc is slightly adjusted.
Preferably, the bamboo pulp in the step e is subjected to pressure filtration by a No. 1, No. 2 and No. 3 filter press, and meanwhile, clear water is circulated to the lower part of the No. 1 filter press by the No. 3 filter press to collect the pressure filtrate. This mode can collect liquid to the utmost extent, simultaneously practices thrift the water source.
Preferably, the filtration in step f is performed by using a plate and frame filter press and a ceramic membrane in sequence.
Preferably, in the step g, the condensate of the fresh bamboo juice stock solution is pumped out through a vacuum flash tank.
In the above technical solution, the micro-airflow and ultrasonic extraction is to extract the material by using a micro-airflow and ultrasonic extraction device, and the micro-airflow and ultrasonic extraction device may be a conventional microwave extractor, including but not limited to a microwave extractor with a model number of FLT-45HME, manufactured by zheng philippit smart appliances ltd.
The invention provides a method for extracting fresh bamboo juice by using ultrasonic waves. The technical scheme is a novel extraction method using micro-airflow and ultrasonic waves on the basis of the prior process of extracting fresh bamboo juice by a cooking method and an extraction method. In the high-temperature steam heating process of the fresh bamboo, fresh bamboo juice on the surface part of the fresh bamboo enters steam firstly, and at the moment, a part of extracting solution can be obtained by cooling the steam. Meanwhile, the fresh bamboo is soaked by high-temperature steam, so that the water content of the fresh bamboo is improved. Meanwhile, the bamboo chips are softened, the micro-airflow and the ultrasonic extraction device are better utilized, the bamboo chips are scattered, the bamboo fibers are not damaged, the original properties of the bamboo fibers are kept, and more extracting solutions are obtained as far as possible.
The bamboo chips treated by the micro-airflow and ultrasonic extraction device have the advantages that because the bamboo fibers are hard and brittle, when the bamboo chips are treated by a high-concentration mill, the gaps between the mill plates are adjusted to be as large as possible, the concentration of bamboo pulp is improved, the fibers are mutually kneaded, fresh bamboo is kneaded and extruded, and meanwhile, the toughness of the bamboo fibers is improved.
Because through little air current and ultrasonic extraction device and high enriched mill, contain bamboo fibre and lignin and some bamboo dregs in the extract, so after plate and frame filter press, can effectual bamboo fibre isolate, again through ceramic filter membrane, can isolate lignin to obtain three products of bamboo fibre, lignin and fresh bamboo juice stoste, abundant utilization bamboo resource.
The invention can realize the extraction of the fresh bamboo juice in the processing process of bamboo products (such as bamboo pulp, bamboo boards and the like), not only improves the utilization rate of raw materials, but also avoids the treatment process of bamboo slag after the extraction of the fresh bamboo juice, can also obtain bamboo fiber and lignin with considerable economic value, has two effects of environmental protection and economic benefit, and has higher practical value.
