Abstract
The present invention discloses a method for continuously extracting chlorophyll from silkworm droppings, which comprises the following steps: (1), impurity removal: cleaning mud and impurities in the silkworm droppings by a dry-cleaning or water washing way; (2), leaching: continuously putting the silkworm droppings into a continuous leacher to be leached with a leaching solution which is continuously replenished in a counter flow way and automatically and continuously exhausting waste slag and the leached solution; (3), evaporation: continuously delivering the leached solution to an evaporator, and recovering and separating residue to obtain paste chlorophyll. The present invention has the advantages that 1, the intermittent production cycle of 1/2 to 1/3 is needed under equal capability; 2, high utilization rate: the silkworm droppings are pulverized into granules and a shape of material is altered, which is favorable for leaching, and the material is continuously fed, so solid and liquid, that is, the silkworm droppings and the leaching solution, are carried out counter flow movement and the yield rate of a product is 5% as high as that of the intermittent production on average; 3, low cost: owing to continuous leaching, evaporation and endless operation, automatization is high, material breakage is small, labor intensity is reduced and production cost is reduced.
Description
Technical field
The present invention relates to a kind of is raw material with the silkworm excrement, the method for continuous extracting chlorophyll.
Background technology
Silkworm excrement is China's geographic silkworm ight soil of breeding silkworms, and chlorophyll content is higher, easily collecting, easily keeping, low price.At present, industrial to extract chlorophyllous method from silkworm excrement be the interval type production method, and this method is put silkworm excrement in lixiviate jar or the cylinder, injects extracting solution, deposit certain hour after, take out extracting solution, then leaching solution is evaporated, obtain chlorophyll.There are long, problems such as raw material availability is low, cost height of production cycle in this method.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of from silkworm excrement the method for continuous extracting chlorophyll.
For achieving the above object, the method for the present invention's continuous extracting chlorophyll from silkworm excrement may further comprise the steps:
(1), removal of impurities: the earth in the silkworm excrement, foreign material are passed through dry-cleaning or washing Ex-all;
(2), leaching: silkworm excrement is dropped into continuous leacher continuously, and with the leaching solution counter-current extraction that constantly replenishes, the solution after waste residue, the leaching is discharged automatically continuously;
(3), evaporation: the solution after will leaching is sent into vaporizer continuously, reclaims the separation resistates and is chlorophyll paste.
For improving extraction yield, before leaching, the silkworm excrement after the removal of impurities is carried out pre-treatment, it is 20～40 purpose particles that the silkworm excrement of Ex-all is pulverized.
Leaching solution is sherwood oil, acetone or both mixed solutions, and silkworm excrement and its weight ratio are 1: 1～6, and Heating temperature is 30-80 ℃.
The method of the present invention's continuous extracting chlorophyll from silkworm excrement is extracted chlorophyllous method with existing interval type and is compared from silkworm excrement, have the following advantages:
1, shorten the production cycle: because silkworm excrement drops into continuous leacher continuously, with the leaching solution counter-current extraction that constantly replenishes, the solution after waste residue, the leaching is discharged automatically continuously, and equal capability only needs the 1/2-1/3 of interval type production cycle;
2, raw material availability height: silkworm excrement is pulverized and to be particle, and material changes shape, favourable leaching, and continuous feeding and discharging in addition, solid-liquid is silkworm excrement and leaching solution countercurrent movement, product yield ratio gap formula on average exceeds 5%.
3, cost is low: since subsequent leaching and evaporation, uninterrupted operation, the level of automation height, material loss is little, and labour intensity reduces, and production cost is lower.
Embodiment
Below in conjunction with specific embodiment, the present invention's method of continuous extracting chlorophyll from silkworm excrement is described in further detail.
Example one
Silkworm excrement 1000 grams have been pulverized in removal of impurities, added continuous leacher gradually, reverse adding 5000 gram sherwood oil and acetone mixed solutions were at 30-80 ℃ of following counter-current extraction 1-4 hour.Leaching liquid is sent into the continuous evaporator evaporation, and controlled temperature 50-80 ℃, forced circulation evaporation is to the 1/4-1/10 volume under normal pressure or decompression, and cold slightly recovery resistates is chlorophyll paste.
Example two
Silkworm excrement 1000 grams have been pulverized in removal of impurities, added continuous leacher gradually, the acetone of reverse adding 6000 grams 95% was at 30-80 ℃ of following counter-current extraction 1-4 hour.Leaching liquid is sent into the continuous evaporator evaporation, and controlled temperature 50-80 ℃, forced circulation evaporation is to the 1/4-1/10 volume under normal pressure or decompression, and cold slightly recovery resistates is chlorophyll paste.
Among the embodiment one, two, leaching is once finished, leaching and evaporation operation continuously.
The present invention's method of continuous extracting chlorophyll from silkworm excrement is not limited to the scope of embodiment, and present embodiment just helps to understand the present invention, and all utilize innovation and creation that the present invention conceives all at the row of protection.
