Abstract
The invention provides a rapid freezing and normal-temperature drying processing method of a traditional Chinese medicine material of Chinese yam, comprising the following steps: placing fresh Chineseyam in a layering way in a refrigeratory at an ultra-low temperature for ultra-low air-cooled quick freezing to ensure deep cooling of the fresh Chinese yam, placing the freezing fresh Chinese yam ina clean, tidy and ventilating place, unfreezing naturally at a temperature of 20-25 DEG C, trickling the water completely, then drying the Chinese yam at a normal temperature, and the dried good is qualified material of prepared drug in pieces of Chinese yam. As sulfur fumigation is not adopted in the drying process, the method ensures that the sulfur dioxide content accords with the food standard (less than 10mg/kg) and the quality of the prepared drug in pieces accords with the time limit requirement for the decoction.
Description
Technical field
The present invention relates to the processing method of raw material of Chinese medicine Rhizoma Dioscoreae, particularly Rhizoma Dioscoreae raw material ultralow temperature, quick freezing do not have the sulfur dry technology.
Background technology
The traditional diamond-making technique of raw material of Chinese medicine Rhizoma Dioscoreae is at first to adopt sulfur fumigation, impels its albuminous degeneration, and the moisture content drop goes out, and carries out natural drying again, is processed into dry product.Because the processing method of traditional sulfur fumigation causes medical material sulfur dioxide to exceed standard, excess sulfur dioxide remnants, not only can cause have sore throat, human body untoward reaction such as stomach discomfort, also influence active constituent content in the decoction pieces.
For reducing content of sulfur dioxide, generally adopt direct oven drying method to process at present, but there is the decocting in water erosion in product, can not guarantee that decoction pieces decocts problems such as time limit.
Summary of the invention
The present invention seeks to solve above deficiency, the content of sulfur dioxide, the solution that reduce the raw material of Chinese medicine Rhizoma Dioscoreae decoct problems such as erosion, through existing different processing technique are investigated, through repetition test, a kind of raw material of Chinese medicine Rhizoma Dioscoreae rapid freezing and normal-temperature drying processing method is provided, make product both reached content of sulfur dioxide meet food standard (＜10mg/kg), meet decoction pieces again and decoct effects such as time limit requirement.The air-cooled freeze cycle of ultralow temperature is short, and the room temperature cost that thaws naturally is low, can be applicable to large-scale production.
Purpose of the present invention realizes by following measure: raw material of Chinese medicine Rhizoma Dioscoreae rapid freezing and normal-temperature drying processing method is finished by following steps:
(1) get the raw materials ready and device processes:
Bright raw material Rhizoma Dioscoreae is removed top layer impurity sandy soil;
Preparation has the air-cooled freezer of super low temperature quick frozen of quick-freezing-35 ℃ ability, has layering compartment facility in the equipment.
(2) ultralow temperature is air-cooled freezing fast: adopt the air-cooled freezer of super low temperature quick frozen, the fresh Rhizoma dioscoreae layering is placed in carries out the air-cooled quick-freezing of ultralow temperature in the freezer, guarantee the fresh Rhizoma dioscoreae deep colling.
(3) thaw naturally: the Rhizoma Dioscoreae that freezes is put into clean, clean and tidy, airy place, keeps 20-25 ℃ and thaw naturally, the abundant drop of its moisture content is gone out.
(4) normal temperature drying: the Rhizoma Dioscoreae of having thawed was naturally carried out normal temperature drying 7-10 days, during stir at any time, the dry product that obtains is qualified Rhizoma Dioscoreae decoction pieces raw material.
The quick air-cooled cryogenic temperature of above-mentioned ultralow temperature is-25 ℃～-30 ℃, and keeping the quick-freezing time is 6-8 hour.
An above-mentioned maintenance 20-25 ℃ natural thawing time is 60-80 hour.
Adopt this processing method, owing to adopt quick freezing, normal temperature drying method, the moisture short time crystallization in the cold process of speed of raw material of Chinese medicine Rhizoma Dioscoreae, air-cooled at ultralow temperature, thaw naturally and the room temperature natural drying process in the quick drop of moisture go out, product is without sulfur fumigation, make product both reached the content of sulfur dioxide food standard (＜10mg/kg), meet decoction pieces again and decoct the time limit requirement.Freeze cycle is short, and the room temperature cost that thaws naturally is low, can be applicable to large-scale production.
The specific embodiment
Embodiment 1: raw material of Chinese medicine Rhizoma Dioscoreae rapid freezing and normal-temperature drying processing method is finished by following steps:
(1) get the raw materials ready and device processes:
Bright raw material Rhizoma Dioscoreae is removed top layer impurity sandy soil;
Preparation has the air-cooled freezer of super low temperature quick frozen of quick-freezing-35 ℃ ability, has 5 layers of compartment facility in the equipment.
(2) ultralow temperature is air-cooled freezing fast: adopt the air-cooled freezer of super low temperature quick frozen, the fresh Rhizoma dioscoreae layering is placed in carries out the air-cooled quick-freezing of ultralow temperature in the freezer, air-cooled cryogenic temperature is-30 ℃, and keeping the quick-freezing time is 7 hours.Guarantee the fresh Rhizoma dioscoreae deep colling.
(3) thaw naturally: the Rhizoma Dioscoreae that freezes is put into clean, clean and tidy, airy place, keeps 25 ℃ and thaw naturally, thawing time is 70 hours, and the abundant drop of its moisture content is gone out.
(4) normal temperature drying: the Rhizoma Dioscoreae of having thawed was naturally carried out normal temperature drying 9 days, during stir at any time, the dry product that obtains is qualified Rhizoma Dioscoreae decoction pieces raw material.
