Technical field

The invention discloses a kind of method of utilizing meal kitchen waste grease to prepare liquid detergent, belong to liquid detergent field.

Background technology

Discarded edible oil and fat are that a kind of kitchen castoff of kitchen castoff claims again changing food waste, comprise the expired food of rubbish from cooking leftovers leftovers (being commonly called as swill) and the discarded edible oil and fat etc. of the generations such as restaurant unit " collectiveity canteen " resident family. According to statistics, China consumes grease approximately 2,200 ten thousand t every year, and wherein approximately 3,300,000 t become waste grease. Discarded edible oil and fat have become a kind of environmental contaminants, and impact food security.

Along with the raising of people's living standard, increasing family adopts liquid detergent to clean tableware, fruit, vegetables. Common liquid detergent, in order to increase the effect of degreasing, increases the irritating composition of human body in liquid detergent the inside, and Long Term Contact can make the coarse of skin change; The sewage that contains house detergent is just discharged in water body without any processing, may impact fish, causes environmental pollution.

Summary of the invention

The technical problem that the present invention mainly solves: the problem that likely affects directly or indirectly health for the chemical residual of current liquid detergent, a kind of method of utilizing meal kitchen waste grease to prepare liquid detergent is provided, meal kitchen waste grease is prepared into anion surfactant by the present invention, recycling Flos Lonicerae extractive solution is as antiseptic, and non-ionic surface active agent, emulsifying agent, solubilizer, chelating agent, spices, the materials such as water are mixed to get liquid detergent, the liquid detergent modest viscosity that the present invention prepares, good stability, not only nontoxic, efficiently, non-stimulated, removal power to spot is strong, and good antimicrobial effect, easily rinse.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

(1) get 3～5kg changing food waste, pull an oar by machinery, after leaving standstill 8～10h, get upper strata edible oil and fat, in grease, add cumulative volume 5～10% clear water, be uniformly mixed 30～40min, centrifugation 15～25min under 4000～5000r/min rotating speed, get supernatant, supernatant is added in round-bottomed flask, put into oil bath and be heated to liquid boiling, in bottle, add gross mass 1.3～1.5% carclazytes to decolour again, after decolouring 30～40min, pour into while hot in the Buchner funnel of putting the gauze that haves three layers, vacuum filtration, impurity is stayed in Buchner funnel, pure edible oil and fat enter in bottle,suction,

(2) in above-mentioned pure edible oil and fat, add the sulfuric acid of cumulative volume 18～25% mass fractions 60% to carry out acidifying, after acidifying 1～2h, wash 2～4 times with distilled water, grease after cleaning joins in reactor, set temperature is 45～65 DEG C, under the condition stirring, in still, add cumulative volume 120～150% diethanol amine, stirring reaction 1～2h again after being warming up to 120～180 DEG C, after finishing, reaction adds again gross mass 1～3% mass fraction 15% NaOH and gross mass 30～40% glutamic acid, stirring reaction 4～6h under the condition stirring, after finishing, reaction obtains anion surfactant, collect, for subsequent use,

(3) get 100～200g honeysuckle, dried, be crushed to 60～70 order powder, add the ethanol water of mass concentration 85% by solid-to-liquid ratio 1:6～1:8, at 40～50 DEG C, soak 4～6h, after soaking, filter, filtrate is sprayed dry, obtain Honegsukle flower P.E, it is added to water by solid-to-liquid ratio 1:10, and heating, until volume is original volume 20～30%, can obtain honeysuckle concentrate;

(4) by parts by weight meter, choose respectively the anion surfactant that 12～15 parts of steps (2) obtain, 3～5 portions of honeysuckle concentrates, 12～15 parts of AEOs, 5～8 parts of alkanolamides, 1～3 part of sodium carbonate, 3～6 parts of toluenesulfonic acid sodium salts, 2～5 parts of sodium metasilicates, 0.1～0.3 part of sodium ethylene diamine tetracetate, with 40～50 parts of deionized waters, under the bath temperature of 65～75 DEG C, be uniformly mixed to transparent viscous fluid, then add 0.2～0.4 part of spices stirring all to obtain liquid detergent.

Application process of the present invention: the liquid detergent that the present invention is made is first diluted with water to 300～500 times while cleaning tableware, after soak time 2～4min, clean with sponge or rag, rinse well with mobile clear water again, also can directly liquid detergent be poured on sponge or rag, after picking a small amount of water, clean tableware, then rinse well with mobile clear water; Clean when vegetables and fruits and first rinse out vegetables and fruits surface contaminants with clear water, then to add dilution liquid detergent concentration be 0.08～0.10% to soak 5～10min, after immersion, rinse 2～3 times with flowing water.

The invention has the beneficial effects as follows:

(1) meal kitchen waste grease is prepared into anion surfactant by the present invention, not only refuse is fully utilized, and obtain surfactant washing force very strong, nontoxic, stimulate little;

(2) to prepare Flos Lonicerae extractive solution be antiseptic in the present invention, Nantural non-toxic, and can play the effect of protection to both hands.
