Abstract

The invention discloses alkaline cleaning composition for dairy product processing equipment. The alkaline cleaning composition is prepared from 1%-5% of a nonionic surfactant, 1%-5% of a stabilizer, 3%-5% of a chelating agent, 0.5%-3% of a penetrating agent, 2%-6% of a dispersing agent, 2%-5% of a bactericide, 20%-30% of strong base, 0.5%-2% of a scale adsorbent and the balance of water. After a surface is treated with the alkaline cleaning composition, the time for foam to reduce to 5 mm or smaller is 10 s or longer. A preparation method of the alkaline cleaning composition comprises the following steps: deionized water and the strong base are mixed and stirred until dissolution; the chelating agent, the dispersing agent, the bactericide and the stabilizer are added sequentially and stirred to dissolution, and the reaction temperature is controlled at 50-60 DEG C in the stirring process; the penetrating agent, the nonionic surfactant and the scale adsorbent are added sequentially and stirred until complete dissolution and clear and transparent solution appearance are realized, and a product is cooled to room temperature. The alkaline cleaning composition is low in corrosivity, strong in cleaning force, little in foam, easy to rinse, resistant to scale redeposition and capable of killing bacteria and inhibiting corrosion and scale, and is an efficient environment-friendly cleaning agent.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to an alkaline cleaning composition for dairy processing equipment and a preparation method thereof. Background technique [0002] Milk is a common high-nutrition food, especially one of the essential staple foods for infants and young children. However, milk is extremely prone to spoilage, which directly affects the health and safety of users. In order to ensure the cleanliness and sanitation of milk from milk source to processing, transportation and storage in the production process, it is necessary to clean the milk-related processing equipment in time. How to choose a cleaning composition is the key to the cleaning work. The traditional cleaning method is to use high temperature and strong alkali. This method has a strong burn force on equipment, strong corrosion, and potential danger to personnel. It also consumes high energy, causes serious alkali pollution, and has ...
