Description

A kind of without phosphorus low-carbon acidity CIP detergents
Technical field
The present invention relates to detergent technical field, specially a kind of without phosphorus low-carbon acidity CIP detergents.
Background technology
In food and drink production, a condition production needs to carry out In-Situ Cleaning, row to production equipment after a certain period of time Industry is known as CIP.The growth of microorganism can be promoted by staying in the residue of equipment surface.For protect consumer from pathogen or The relevant potential health hazard of poisonous substance influences and keeps product quality, it is desirable that residue is routinely removed from surface.It is in situ clear Clean technology cleans the inside of food manufacturing apparatus system using the combination of chemical action, mechanism, temperature action, and saving disappears The dismounting of time-consuming and the big system of labor intensity and artificial cleaning, improve equipment service efficiency.CIP cleaning modes be suitable for from The internal element removing dirt of slot, pipeline, pump and other process equipments.Method and system for CIP is often used in cleaning The process equipment used in dairy produce, food and beverage industry.CIP operations generally include the cycle of water, chemicals with periodically clear Clean production system.Normally, CIP method is cleaned including five steps, and drift is recycled with the first step of process water (process water) It washes, then compound alkaline cleaner recycles cleaning for the second time, again the third step cycle of process water (process water) Rinsing, then the 4th cycle cleaning of combination of acidic detergent, the 5th step cycle rinsing of last process water.Food and drink is used CIP detergents mainly have compound alkaline cleaner and combination of acidic detergent, and the main function of alkaline cleaner is dissolving food In organic dirt such as carbohydrate, protein and grease, combination of acidic detergent is mainly used for dissolving inorganic salts precipitation dirt. Cleaning process is generally five-step approach, because the product of processing is different, in food industry production generated dirt be not with it is single at The form divided exists, and the cleaning of food industry machine needs alternately to be cleaned with compound alkaline cleaner and combination of acidic detergent. Common combination of acidic detergent is enough for CIP applications, and phosphorus series compound is contained in existing detergent, higher is contained The organic compound of amount, if Chinese Patent Application No. is a kind of food industry containers for proposing of CN201110300518.3 with novel Acidic cleaner.These phosphorus series compounds include phosphoric acid and organic phosphoric acid, its significance lies in that providing corrosion inhibition, organic compound Including organic acid, surfactant, meaning is to provide acid ingredient respectively, reduces surface tension, improves cleaning efficiency.Phosphorus Based compound can cause body eutrophication, higher organic compound content that water body COD value can be caused to increase, be unfavorable for ring It protects.Requirement of the national standard for without phosphorus detergent is 1.1% (with P2O5Meter), however be protection mineral water resource, this standard is not The requirement that many local governments require mineral water manufacturing enterprise that must use without phosphorus detergent can be met.Some combination of acidic clean Agent fails to carry out stainless steel equipment certain passivation in CIP, and when food and drink being caused to produce, especially heat fills production The ring cylinder of line, it may appear that since equipment passivating film is imperfect, is generated in production process dirt is attached to equipment surface and cause Corrosion.For this purpose, it is proposed that a kind of without phosphorus low-carbon acidity CIP detergents.

2, corrosion inhibiting and descaling agent
From document and data check, there are many nitric acid corrosion inhibiter, such as LAN826, but due to the toxicity of this kind of corrosion inhibiter Other features are not suitable for food beverage industry.
Polycyclic oxycarboxylic acid is a kind of polynary anti-incrustation corrosion inhibitor of without phosphorus, non-nitrogen " green " environment-friendly type.Polycyclic oxycarboxylic acid is to water In calcium carbonate, calcium sulfate, barium sulfate, calcirm-fluoride and silicon dirt have a good scale inhibition and dispersion performance, scale inhibition effect has better than common Machine phosphine antisludging agent.Polycyclic oxycarboxylic acid has certain corrosion inhibition simultaneously, is a kind of polynary antisludging agent.
Acrylic acid-acrylic ester-sulfonate terpolymer contains strong acid, weak acid and nonionic base on strand simultaneously Group, it be suitable for high temperature, high pH value, it is high firmly with it is high-alkali under the conditions of use, in water iron oxide, calcium phosphate, trbasic zinc phosphate and The deposition of calcium carbonate has excellent inhibiting effect, has higher calcium tolerance.
Imidazoline surfactant is a kind of nitrogenous organic inhibitor with surface-active, is had the characteristics that down to still, Surface tension can effectively be reduced.
3, surfactant
Specially addition surfactant reduces surface tension to the present composition, using the combination of corrosion inhibiting and descaling agent come Reduce product surface tension.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of without phosphorus low-carbon acidity CIP cleanings that the invention proposes Agent has good dirt-removing power and slow-release capability, will not cause the damage of rustless steel container, does not contain phosphoric acid and organic phosphoric acid Equal phosphorus series compounds, will not cause the pollution of environment, meet and use needs.
