Embodiment 1

[0075] Step 1: Weigh 40 kg of crushed mulberry leaves and mulberry branch powder, add 260 kg of water for ultrasonic extraction, and remove large particles through coarse filtration to obtain 240 L of filtrate;

[0076] Step 2: The filtrate enters the ceramic membrane system for clarification and removal of impurities. The operating pressure is 0.15Mpa, the pore size of the ceramic membrane is 200nm, the operating temperature is controlled within 60°C, and the continuous operation is 1000min. During the process, the concentrated solution is washed with water, and the average membrane flux is about 78LMH ( Liter / square meter per hour), to obtain 360L ceramic membrane dialysate;

[0077] Step 3: The ceramic membrane dialysate enters the roll-type reverse osmosis equipment for concentration, the operating pressure is 25bar, the operating temperature is controlled within 35°C, and the processing time is 470 minutes to obtain 324L of reverse osmosis product water and 36L of reverse ...

Embodiment 2

[0082] Step 1: Weigh 100kg of crushed mulberry leaves and mulberry branch powder, add 650kg of water for ultrasonic extraction, and remove large particles by coarse filtration to obtain 600L of filtrate

[0083] Step 2: The filtrate enters the ceramic membrane system for clarification and removal of impurities. The operating pressure is 3bar, the operating temperature is controlled within 60°C, the operating pressure is 0.5Mpa, the ceramic membrane pore size is 500nm, and the continuous operation is 920min. The volume is about 88LMH (liter / square meter per hour), and 900L ceramic membrane dialysate is obtained;

[0084] Step 3: The ceramic membrane dialysate enters the dish-type reverse osmosis pilot plant for concentration, the operating pressure is 69bar, the operating temperature is controlled within 35°C, and the treatment time is 348 minutes to obtain 555L of reverse osmosis product water and 45L of reverse osmosis concentrate;

[0085] Step 4: The reverse osmosis concent...

Abstract

The invention discloses a method for continuously extracting DNJ, flavonoids and polysaccharides from a moraceae plant. The method is characterized by comprising the following steps: performing ultrasonic extraction on raw materials, performing ceramic membrane filtration, performing reverse osmosis concentration and performing consecutive ion exchange for three times to respectively obtain the DNJ, the flavonoids and the polysaccharides. The invention further comprises a system for continuously extracting the DNJ, the flavonoids and the polysaccharides from the moraceae plant. The method andthe system disclosed by the invention are simple in process, capable of quickly realizing the separation and the purification of mulberry leaf and mulberry twig extracts at a time, continuous in feeding and discharging, stable in operation, high in product content and fully-automatic in system operation, saves a large quantity of manpower and material resources and is suitable for industrial popularization.

Description

technical field [0001] The invention relates to the technical field of separation of effective components of traditional Chinese medicine, in particular to a system and method for simultaneously and continuously separating and purifying DNJ, flavonoids and polysaccharides from Moraceae plants using continuous ion exchange technology. Background technique [0002] Mulberry is a plant of the genus Morus in the family Moraceae, which was first recorded in "The Book of Songs", also known as iron fan. Mulberry has a very long history in my country. Since the appearance of silkworm rearing in the distant ancestors, there has been the cultivation of mulberry. In traditional sericulture production, a small part of mulberry leaves and mulberry branches are used as fuel or silkworm rearing, and the resource value has not been well developed. In recent years, although people have realized the comprehensive utilization of mulberry leaves and mulberry branches to increase the value of m...
