Description

Composite alkaline cleaning agent

Technical Field

The invention belongs to the technical field of cleaning agents, and particularly relates to a composite alkaline cleaning agent.

Background

Safety and sanitation are the essential conditions of the food industry, so that each link of food production needs to be cleaned and disinfected in time. The raw materials for food processing and the sources thereof are various, the same raw material also has various varieties, and different products can be processed, so that the complexity of food equipment and processes is determined. At the same time, the cleaning of the equipment and tools is also complicated. The chemical cleaning process can adopt different formulas and cleaning processes according to different equipment, dirt and other conditions, and can well meet the requirements of different dirt, cleaning machines, equipment and cleaning processes.

The types of soils common to the food industry are sugars, starches, proteins, fats, mineral scale and the like. The saccharide is polyhydroxy organic compound, is easy to dissolve in water and is easy to clean. The starch can be hydrolyzed into polysaccharide and monosaccharide, and can be further cleaned. The protein is easy to clean under alkaline condition, and the grease and mineral scale can be cleaned under the action of alkaline, chelating agent and surfactant.

Chinese patent publication No. (CN107937171A) discloses a low-foam green CIP sterilization concentrated cleaning agent, which is prepared from 1-5% of alkyl glycoside, 1-12% of fatty acid methyl ester ethoxylate, 0-6% of modified grease ethoxylate, 0-8% of modified grease ethoxylate sulfonate, 0-3% of coconut oil fatty acid diethanolamide 6501, 0.5-2.0% of undecylimidazoline amphoteric surfactant, 1-5% of auxiliary agent, 1-6% of chelating agent, 0-2% of penetrating agent, 0.1-0.4% of defoaming agent, 0.1-0.3% of bactericide, 0.05-0.15% of pH regulator and the balance of deionized water in percentage by weight.

Chinese patent publication No. CN106479729A discloses a high-efficiency CIP alkaline cleaning agent and a preparation method thereof, wherein the high-efficiency CIP alkaline cleaning agent comprises, by weight, 0.5-1.0% of modified alkyl glycoside AS48 and/or alcohol ether glycoside, 2.0-5.0% of sodium gluconate, 1.0-5.0% of EDTA-4Na1, 20.0-40.0% of sodium hydroxide, 0.5-3.0% of ethylene glycol PO-EO block copolymer, 0.1-0.5% of urea and 0.1-0.5% of ethylene oxide-propylene oxide trans-block copolymer.

The CIP cleaning agent disclosed in the above two references is complicated in composition and troublesome to manufacture.

Disclosure of Invention
