Description

A kind of fresh bamboo juice extraction process

Technical field

The present invention relates to a kind of extraction process of natural element, more particularly, relate to a kind of fresh bamboo juice extraction process.

Background technology

Fresh Succus Bambusae is as a kind of Chinese medicine, and its medical value, just on the books as far back as Compendium of Material Medica, it is sweet, nontoxic that it has abnormal smells from the patient, cures mainly sudden and violent apoplexy, migratory arthralgia, in the heart large blood, only unhappy, effect such as to quench one's thirst.And record the drug standard Chinese crude drug promulgated by the ministries or commissions of the Central Government first in 1992.Modern study shows that wherein tyrosine accounts for the 55-68% of total content containing 10 several amino acids in fresh Succus Bambusae, also containing organic compound compositions such as guaiacol, gluconic acid, salicylic acid, phenol, germanium, silicon; To cough and bronchitis, there is therapeutic effect; Along with development of modern scientific technology, fresh Succus Bambusae is widely used in medicine, food and drink, the aspects such as health product.

The preparation method of current fresh Succus Bambusae mainly has following several, and one is traditional firing process, and this extracting method bamboo timber resource waste is large, Succus Bambusae extraction of the juice is few, Succus Bambusae difficult quality controls, and has pyrotechnics and the smell of burning, can not be utilized after bamboo wood burning, thus production cost is high, two is adopt cooking process, and it is that hot digestion filters to obtain fresh Succus Bambusae by fresh bamboo wood through soaking, but owing to containing many pigments in the fresh Succus Bambusae that the method is extracted, though the plurality of impurities composition warp such as natural gum and starch

Heating subpackage, the techniques such as simple sterilizing, the fresh Succus Bambusae quality of preparation is very unstable, is difficult to ensure the quality of products.

Chinese Patent Application No. to be 96102354.6 " Succus Bambusae extracting method " and China Patent No. be 200510022427.2 " method for extracting fresh bamboo juice " its select fresh without moth without mottled bamboo material, pass through high temperature steaming, collect the fresh Succus Bambusae that intermediate period steams, make the former finished product of fresh Succus Bambusae.This fresh Succus Bambusae product obtained by direct steaming and decocting, because of without subsequent handling process, product quality is difficult to obtain and ensures, simultaneously owing to only collecting the drop liquid of distillation interlude, greatly reduces fresh Succus Bambusae and extracts yield; And obtained fresh Succus Bambusae product is only primary product.At present also end is seen to have and after steaming and decocting, to be prepared the former finished product of fresh Succus Bambusae carry out filtering, process, be separated the report preparing fresh Succus Bambusae product.

Summary of the invention

Object of the present invention will provide a kind of fresh bamboo juice extraction process exactly, its be by the thick bamboo juice that obtained by steaming and decocting after filtration, be separated after obtained fresh Succus Bambusae product, steady quality, long shelf-life, effective component content is high.

Fresh bamboo wood is prepared after thick bamboo juice through steaming and decocting by technical solution of the present invention, carries out extracted from bamboo juice by following processing step:

Initial filter: thick bamboo juice flame filter press carries out initial filter, obtains just bamboo juice;

Fine straining: at the beginning of bamboo juice filter through ion exchanger, obtain smart bamboo juice;

Be separated: by smart bamboo juice centrifugal separating device and/or Ultra filtration membrane, obtain separation bamboo juice;

Sterilization manufactured goods: will bamboo juice be separated sterile-processed, and obtain fresh Succus Bambusae product.

Described fresh bamboo juice extraction process, is preferably undertaken by following processing step:

Initial filter: the flame filter press being polypropylene or byssus or stainless (steel) wire by thick bamboo juice filter membrane filters, controls filtrate temperature-5 ~ 60 DEG C; Obtain just bamboo juice;

Fine straining: be that diatomaceous ion exchanger filters through exchange media by first bamboo juice, control filtrate temperature-5 ~ 60 DEG C, time 20 ~ 40min, obtains smart bamboo juice;

Be separated: smart bamboo juice centrifugal separating device is separated with hollow fiber ultrafiltration membrane, obtains separation bamboo juice;

Sterilization manufactured goods: separation bamboo juice is disinfected at 100 ~ 130 DEG C of temperature, is fresh Succus Bambusae product.

Thick bamboo juice of the present invention prepares in bamboo product process with fresh bamboo wood, the bamboo juice collected when carrying out high temperature steaming process to the fresh bamboo wood after processing.

Centrifugal device of the present invention is high speed centrifuge, and its working speed is 8000 ~ 19000r/min.

The fresh Succus Bambusae that the present invention adopts this technical scheme to extract, with fresh bamboo for raw material prepare bamboo product time, when high temperature high pressure process being carried out to fresh bamboo material with steam when preparing bamboo flooring especially, namely in bamboo wood carbonized processing procedure, as the thick bamboo juice of raw material of the present invention's processing after the solution collection produced, and it is as discharging of waste liquid to bamboo product, bamboo flooring manufacturing enterprise, also extreme influence can be caused to environment; Then significantly production cost is reduced to the present invention, and saves vaporize draw

Operation.Product detects through Yichun City food and medicine inspection institute of Jiangxi Province and meets fresh Succus Bambusae medicine and food parameter request, because high-precision filtration is under the prerequisite retaining former organic component, impurity is filtered, prevent impurity from fermenting and go mouldy, it is long that fresh Succus Bambusae product deposits shelf lives, and purity, precision, transparency are high.Filtration MW is at 0.1-0.001 micron order, and its sweet in the mouth is cool.

Detailed description of the invention

Below in conjunction with embodiment, the present invention will be described.
