CIP cleaning system to ensure a certain cleaning effect, improve product safety; save operating time, improve efficiency; save labor, protect the operation of security; save water, steam and other energy, reduce the amount of detergent; production equipment can be large-scale, High level; extend the service life of the production equipment. The role of CIP cleaning mechanism Chemical energy is mainly added to the chemical reagents generated, it is the most important factor in determining the washing effect.

Acid and alkali detergent advantages are: pickling can be removed by chemical reaction of calcium and mineral oil residues; alkaline washing can be removed through the saponification of fat and protein residues.

Disadvantages are: poor washability.

The advantages of sterilizers are: the bactericidal effect is rapid and effective for all microorganisms; it is generally non-toxic after dilution; it is not affected by water hardness; film is formed on the surface of the equipment; easy to measure; easy to measure;

Shortcomings are: a special taste; need a certain storage conditions; different concentrations of sterilization effect difference; easy to freeze when the temperature is low; improper use will produce side effects; mixed with the bactericidal effect decreased significantly; spilled when easy to contaminated environment and leave traces The

Acid in acid and alkali detergent is 1% -2% nitric acid solution, alkali refers to 1% -3% sodium hydroxide at 65 ℃ -80 ℃ use. The fungicide is a frequently used chlorine-based bactericide such as sodium hypochlorite. Thermal energy in a certain flow, the higher the temperature, the smaller the viscosity coefficient, the greater the Reynolds number (Re). The rise in temperature can usually change the physical state of the dirt, accelerate the chemical reaction rate, while increasing the solubility of dirt, easy to clean off the impurities when the solution, thereby improving the cleaning effect, shorten the cleaning time. The size of the kinetic energy is measured by Re.

Re general criteria for: from the wall of the thin liquid, slot Re> 200, tube Re> 3000, and Re> 30000 the best results. Water dissolution: water as a polar compound, the oil-based dirt almost no dissolution, the carbohydrates, protein, lower fatty acids have a certain role in the dissolution of electrolytes and organic or inorganic salts stronger. The role of movement, such as stirring, spray cleaning fluid pressure and friction generated. Factors affecting the cleaning effect: the degree of contamination of the equipment, the nature of the pollutants and the production process of the product are important reasons for determining the cleaning effect. If the cleaning conditions are not determined according to their characteristics, it is difficult to achieve the desired purpose or cause the cleaning costs Too high defects. Cleaning agent types, as of 2012 food industry application of many types of cleaning agents, mainly acid and alkali, etc., of which the most widely used sodium hydroxide and nitric acid. Alkaline detergents have a good effect on the removal of higher protein content, but have a certain corrosion effect on food rubber gaskets. Acid detergent on the alkaline cleaning agent can not be removed stubborn dirt has a good effect, but the metal has a certain corrosive, should add some anti-corrosion agent or rinse with water. Cleaning agents are also surfactants, chelating agents, etc., but only when the special needs to use, such as cleaning water hardness can be used when the chelating agent to remove metal ions. Cleaning agent concentration to improve the concentration of cleaning agent, may be appropriate to shorten the cleaning time or make up for the lack of cleaning temperature. Increased cleaning agent concentration will result in increased cleaning costs, and the increase in concentration does not necessarily improve the cleaning effect, so manufacturers need to determine the appropriate concentration according to the actual situation. Washing temperature Generally speaking, the temperature of each increase of 10 ℃, the chemical reaction rate will increase 1.5-2.0 times the cleaning speed is also a corresponding increase in cleaning effect is better. The cleaning temperature is generally not lower than 60 ° C. Cleaning time is affected by many factors such as cleaning agent type, concentration, cleaning temperature, product characteristics, production pipeline layout and equipment design. Cleaning time must be appropriate, too short can not be effectively removed dirt, too long is a waste of resources.
