Liquid metering tanks have different names according to different uses. It is used in pharmaceutical liquid metering systems. In the food and dairy industry, some are known as mixing tanks, pretreatment tanks or aseptic liquid mixing tanks. According to the volume of the metering tank, it can be divided into laboratory metering tank, pilot metering tank and large metering tank. According to whether it can be moved, it can be divided into fixed metering tank and mobile metering tank, and some can be disassembled. According to different stirring forms, there are magnetic stirring liquid metering tanks, stirring blade liquid metering tanks and buffer liquid metering tanks. According to different structures, it can be divided into single-layer liquid metering tank, thermal insulation stirring liquid metering tank and three-layer thermal insulation liquid metering tank.

HAPOO provides fixed cleaning nozzles to provide solutions for cleaning and maintenance of pharmaceutical metering tanks. The working principle of the CIP system cleaning ball is to spray water column through a large number of small holes to clean the inner wall of the tank. The CIP cleaning system can ensure a certain cleaning effect and improve product safety; save operating time and improve efficiency; save labor costs and ensure safe operation; save energy such as water and steam and reduce detergent consumption; production equipment can be operated automatically on a large scale; The mechanism of CIP cleaning is mainly the chemical energy generated by the chemical reagents added to it, which is the main factor determining the cleaning effect. In general, manufacturers can choose detergents according to the nature and degree of pollution of the object to be cleaned, the materials of the constituent substances, water quality, the selected cleaning method, cost and safety. Commonly used detergents are acidic, alkaline and bactericides.

The advantages of acidic and alkaline detergents are: kills all microorganisms; better removal of organic matter.

The disadvantages are: strong irritation to the skin; poor washing performance.

The advantages of bactericides are: rapid bactericidal effect, effective for all microorganisms; generally non-toxic after dilution; not affected by water hardness; forming a film on the surface of equipment; easy to measure concentration; easy to measure;

The disadvantages are: special smell; certain storage conditions are required; the bactericidal effect of different concentrations is very different; it is easy to freeze when the temperature is low; improper use will cause side effects;

The acid in the acid-alkaline detergent refers to 1%-2% nitric acid solution, and the alkali refers to 1%-3% sodium hydroxide used at 65°C-80°C. The disinfectant is a commonly used chlorine-containing disinfectant, such as sodium hypochlorite. Under the action of a certain flow of thermal energy, the higher the temperature, the smaller the viscosity coefficient and the larger the Reynolds number (Re). The increase in temperature can usually change the physical state of the dirt, accelerate the chemical reaction speed, and increase the solubility of the dirt, which facilitates the dissolution and shedding of impurities during the cleaning process, thereby improving the cleaning effect and shortening the cleaning time. The magnitude of kinetic energy is measured by Re.
