Abstract
The invention relates to cleaning agents for equipment of the dairy industry. The cleaning agents are mainly used for cleaning of inner surfaces of containers and pipelines of raw milk and other equipment for raw milk. The cleaning agents include an acidic cleaning agent and an alkaline cleaning agent. The acidic cleaning agent comprises, by mass, the following components: 10-40% of nitric acid, 1-15% of phosphoric acid, 0.1-1% of an acid chelating agent and 55-85% of water, wherein the acid chelating agent is composed of 1-15% of phosphoric acid, 0.05-11% of ethylenediaminetetra-acetic acid (EDTA), 0.01-0.5% of diethylenetriaminepenta-acetic acid (DTPA) and 74-95% of water. The alkaline cleaning agent comprises the following components: 14-39% of sodium hydroxide, 0.1-1% of an alkaline chelating agent and 60-85% of water, wherein the alkaline chelating agent comprises the following components: 1-15% of potassium hydroxide, 0.01-11% EDTA, 0.01-0.5% DTPA and 74-95% of water.
Description
technical field [0001] The invention relates to a cleaning agent for equipment in the dairy industry, which is mainly used for cleaning the inner surfaces of containers, pipes and other raw milk equipment used in the raw milk collection process. Background technique [0002] Traditional dairy industry equipment cleaning uses industrial strong acid and strong alkali, although it also plays a role in cleaning equipment, but there are obvious deficiencies in the following aspects. For the human body, the burning power of industrial acid and alkali is very strong, and it is very dangerous and inconvenient to use. At the same time, industrial acid and alkali are very corrosive to equipment, which greatly increases the consumption and cost of spare parts, especially for rubber sealing rings, carbon black often appears after pickling, and the damage is relatively serious. In terms of environmental protection, a large number of acid and alkali pollution. Will cause adverse effects...
