Embodiment Construction
[0023] A method for extracting active ingredients from dehydrated garlic slice processing wastewater, comprising the following steps:
[0024] (1) Filter 2,500 kg of dehydrated garlic slice processing wastewater through a 0.5 μm filter bag to filter out visible solid particles in the wastewater, and collect about 2,440 kg of filtrate; the visible solid particles are about 50 Kg, which can be processed into garlic powder;
[0025] (2) Filtrate the filtrate collected in step (1) through a 50nm ceramic membrane to remove all residual tiny solid particles and some macromolecular garlic proteins, and collect about 2420 kg of filtrate; the tiny solid particles and part of macromolecular garlic proteins are about 15Kg, can be processed into garlic powder;
[0026] (3) Concentrate the filtrate collected in step (2) to a concentration of 10-15% with a 100 Dalton nanofiltration membrane to obtain a concentrated solution of about 100 kg;
[0027] (4) Put the concentrated solution with a...

The invention discloses a method of extracting an active ingredient from dehydrated garlic slice processing wastewater. The method comprises the steps of performing fractional separation on the garlicslice processing wastewater with a filter bag and a ceramic membrane component in different apertures, performing concentration with a nanofiltration membrane, performing steam negative pressure secondary concentration on obtained concentrated liquid, and then performing vacuum-drying and grinding to form extract powder of the active ingredient of the garlic wastewater. According to the method, since membrane separation, the steam negative pressure secondary concentration and the vacuum-drying are combined, an extraction rate can be effectively increased and reach above 99%; an extraction condition is mild; the damage to activity of the active ingredient of garlic is avoided; a product is good in quality; the method is low in operating cost, environment-friendly, energy-saving and simplein technology; the method has the most important characteristics that a pure physical method is adopted; no chemical reaction occurs in the entire process; no secondary pollution is caused; the technology is environment-friendly and green and provides a guaranty that the product serves as a raw material of a health care product and a drug; and an effective approach is provided for comprehensive utilization of the garlic slice processing wastewater.
Description
technical field [0001] The invention relates to the technical field of multistage physical method extraction, in particular to a purely physical method for extracting active ingredients from dehydrated garlic flake processing wastewater. Background technique [0002] Garlic chip processing wastewater is high organic matter wastewater containing allicin, its allicin content is about 0.06mg / mL, total sugar content is about 6.0mg / mL, protein content is about 0.2mg / mL, and has strong irritating garlic Odor, the pH value is usually between 5.5-6.5, and the COD content can reach more than 20,000 units. [0003] The polysaccharides in garlic are the organic pollutants with the highest content in garlic slice wastewater, and the sugars are mainly garlic polysaccharides and garlic oligosaccharides. The content of polysaccharides can reach 26.5% of the total weight of fresh garlic, and a small part of carbohydrates exists in the form of glycoproteins in the garlic slice production wa...
