Cleaning points of stainless steel liquid tank
The stainless steel liquid distribution tank can ensure a certain cleaning effect and improve the safety of the product; save operating time and improve efficiency; save labor and ensure operating safety; save water, steam and other energy, reduce detergent consumption. The production equipment can be large-scaled and automated The high level extends the service life of production equipment. The mechanism of CIP cleaning The chemical energy is mainly produced by the chemical reagents added to it, and it is the most important factor that determines the cleaning effect. Generally, manufacturers can choose detergents according to the nature and degree of pollution of the cleaning object, composition material, water quality, selected cleaning method, cost and safety. Commonly used detergents are acid, alkali detergent and sterilizing detergent.
The advantages of acid and alkali detergents are: it can kill all microorganisms; the effect of removing organic matter is better. The shortcomings of the stainless steel liquid tank are: strong irritation to the skin and poor washability.
The advantages of sterilizing agents are: rapid sterilization effect, effective for all microorganisms; generally non-toxic after dilution; not affected by water hardness; forming a film on the surface of the equipment; easy to measure the concentration; easy to measure; can remove odor.
The disadvantages are: a special taste; certain storage conditions are required; the sterilization effect of different concentrations is very different; it is easy to freeze when the temperature is low; improper usage will produce side effects; the sterilization effect of mixed dirt is significantly reduced; it is easy to stain the environment when it is spilled and leave traces .
Acid in acid-base detergent refers to 1%-2% nitric acid solution, alkali refers to 1%-3% sodium hydroxide used at 65℃-80℃. Sterilizers are frequently used chlorine-based bactericides, such as sodium hypochlorite. Under a certain flow rate, the higher the temperature, the lower the viscosity coefficient and the greater the Reynolds number (Re). The rise in temperature can usually change the physical state of the dirt, accelerate the chemical reaction rate, and increase the solubility of the dirt at the same time, which facilitates the removal of the impurity solution during cleaning, thereby improving the cleaning effect and shortening the cleaning time. The amount of kinetic energy is measured by Re.
