Abstract

The alkaline cleaning composition for dairy product processing equipment disclosed by the invention includes: 1-5% nonionic surfactant, 1-5% stabilizer, 3-5% chelating agent, 0.5-3% penetrant, 2- 6% dispersant, 2-5% bactericide, 20-30% strong alkali, 0.5-2% dirt adsorbent and the balance water. After treating the surface with this alkaline cleaning composition, the foam is reduced to less than 5 mm. The time is no more than 10 seconds. The preparation method of the cleaning composition includes the following steps: mix deionized water and strong alkali and stir until dissolved; add chelating agent, dispersant, bactericide and stabilizer in sequence, stir until dissolved, and control the reaction temperature at 50-60°C during the stirring process ℃; add penetrant, nonionic surfactant, and dirt adsorbent in sequence, stir until complete dissolution and the solution appears clear and transparent, and cool to room temperature. The alkaline cleaning composition disclosed by the invention is less corrosive, has strong cleaning power, less foam, is easy to rinse, resists dirt redeposition, can sterilize and inhibit corrosion and scale, and is an efficient and environmentally 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 ...
