Product Description
Since the 1980s, the cleaning of equipment has been replaced by machinery. In particular, dairy products, beverages and other factories that adopt pipelined continuous operation. In many dairy factories, automatic on-site cleaning is adopted, that is, the water and washing liquid used for flushing are circulated in a closed circuit in the pipeline and production line of the equipment, and there is no need to disassemble the equipment. This technology is called CIP, or cleaning in place. CIP is widely used in food and beverage production enterprises with a high degree of mechanization, such as beverages, dairy products, fruit juice, fruit pulp, jam, wine and so on. In situ cleaning does not need to disassemble or move the device. Detergent and washing water are used to wash the internal surface of the equipment with high-speed liquid flow to form a mechanical action to wash away the dirt. This action is effective for the cleaning of pipes, pumps, heat exchangers, separators and valves. It can be used for cleaning and purification of production equipment with strict hygiene level requirements.
CIP cleaning system can ensure certain cleaning effect and improve product safety; Save operation time and improve efficiency; Save labor and ensure operation safety; Save water, steam and other energy and reduce the amount of detergent; The production equipment can realize large-scale and high automation level; Extend the service life of production equipment. The action mechanism of CIP cleaning chemical energy is mainly produced by the chemical reagent added into it, which is the main factor determining the washing effect.
The advantages of acid and alkali detergents are: pickling can remove calcium salt and mineral oil residues through chemical reaction; Alkali washing can remove residues such as fat and protein through saponification reaction.
Disadvantages: poor washability.
The advantages of sterilizing agent are: rapid sterilization effect and effective for all microorganisms; It is generally non-toxic after dilution; Not affected by water hardness; Form a film on the surface of the equipment; The concentration is easy to measure; Easy to measure; Odor can be removed.
Disadvantages: special taste; Certain storage conditions are required; The germicidal efficacy of different concentrations varies greatly; It is easy to freeze when the temperature is low; Improper use will produce side effects; The bactericidal effect of mixed dirt decreased significantly; When spilled, it is easy to pollute the environment and leave traces.
Acid in acid-base detergent refers to 1% - 2% nitric acid solution, and alkali refers to 1% - 3% sodium hydroxide used at 65 ºC - 80 ºC. Bactericides are chlorine bactericides often used, such as sodium hypochlorite. Under a certain flow rate, the higher the temperature, the smaller the viscosity coefficient and the larger the Reynolds number (RE). The rise of temperature can usually change the physical state of the dirt, accelerate the chemical reaction speed, increase the solubility of the dirt, and facilitate the shedding of the impurity solution during cleaning, so as to improve the cleaning effect and shorten the cleaning time. The amount of exercise energy is measured by re.
The general standard of re is: for the thin liquid flowing down from the wall, the groove type RE > 200, the pipe type RE > 3000, and the effect of re > 30000 is the best. Dissolution of water: water is a polar compound, which has almost no dissolution effect on oily dirt, has a certain dissolution effect on carbohydrates, proteins and low-grade fatty acids, and has a strong dissolution effect on electrolytes and organic or inorganic salts. Mechanical action: the action produced by movement, such as the pressure and friction generated by stirring and spraying cleaning fluid. Influencing factors of cleaning effect: the degree of equipment pollution, the nature of pollutants and product production process are important reasons for determining the cleaning effect. If the CIP conditions are not determined according to its characteristics during cleaning, it is difficult to achieve the ideal purpose or lead to the defect of high cleaning cost. Types of cleaning agents: as of 2012, there are many types of cleaning agents used in the food industry, mainly including acid and alkali, among which sodium hydroxide and nitric acid are most widely used. Alkaline detergents have a good effect on removing dirt with high protein content, but they have a certain corrosive effect on food rubber gaskets. Acid detergent has a good effect on the stubborn scale that cannot be removed by alkaline detergent, but it has a certain corrosivity to metal. Some anti-corrosive agents should be added or washed with clean water. Cleaning agents include surfactants and chelating agents, but they are only used when special needs are met. For example, chelating agents can be used to remove metal ions when the hardness of cleaning water is high. When the concentration of cleaning agent is increased, the cleaning time can be appropriately shortened or the shortage of cleaning temperature can be made up. The increase of cleaning agent concentration will increase the cleaning cost, and the increase of concentration may not effectively improve the cleaning effect. Therefore, it is necessary for the manufacturer to determine the appropriate concentration according to the actual situation. Generally speaking, when the temperature of the washing solution increases by 10 ºC, the chemical reaction speed will increase by 1.5-2.0 times, the cleaning speed will also increase accordingly, and the cleaning effect is good. Generally, the cleaning temperature shall not be lower than 60 ºC. Cleaning time is affected by many factors, such as cleaning agent type, concentration, cleaning temperature, product characteristics, production pipeline layout and equipment design. The cleaning time must be appropriate. If it is too short, the dirt cannot be effectively removed, and if it is too long, resources will be wasted.
