Detailed description of the main configuration and testing standards for small sterilization pots

The main body of the small sterilizer is equipped with a three-cm thick insulation layer, which reduces heat loss and protects the working environment. Water bath sterilization, thermometer and temperature sensor are completely immersed in hot water, and the temperature inside the pot can be observed at any time. When the temperature in the sterilization pot reaches the predetermined design sterilization temperature, the temperature is automatically stopped in the pot, and the automatic timing starts. When the temperature inside the sterilization pot is lower than the set temperature, the automatic control system is completely, accurately and timely heated, and the temperature difference accuracy reaches ± Within 0.5 °C, it meets international standards.

In order to better eliminate and inhibit the survival and reactivation rate of bacteria, the goods must be quickly and rapidly reduced to the ideal temperature at high temperature. Our company uses high-power, high-lift, high-flow cold water supply pump for five minutes. The injection of cooling water is completed in order to preserve the flavor, color and taste of the goods as perfectly as possible.

The new cooling method of the small sterilizer is to change the temperature of the spray to the temperature of the flood irrigation. During the cooling process, the pressure does not fall, and the packaged articles are separated and bubble bubbles are caused by the pressure drop during the cooling, and the product is more effectively solved. Corrosion occurs during the warranty period to ensure the sterilization success rate of the product.

The small sterilization pot reduces the steam consumption, and the steam and the atomized sterilizing water are directly mixed in the sterilizer to increase the speed of temperature rise and fall. A small amount of process water is quickly circulated to quickly reach the desired sterilization temperature. Water is sprayed from different angles, steam and water are mixed and convective, and the temperature of the horizontal sterilization pot is evenly distributed. The working environment is low-noise and quiet. The pressure of the whole production process is constantly adjusted to adapt to the changes in the internal pressure of the product packaging. The small sterilization pot makes the deformation of the product packaging low, especially suitable for products containing gas packaging. Eliminate secondary pollution when the product is cooled.

Two large detection standards for small sterilization pots:

1, flaw detection

A of the equipment cylinder, food small sterilization pot, Class B welded joints should be subjected to local ray inspection, the length of inspection is not less than 20% of the length of each welded joint, and not less than 250mm. The detection technology level is not lower than AB grade. The result is in line with NB/T 47013.2-2015 <<Non-destructive testing of pressure equipment>>, grade III qualified; (since the design structure covers the weld, small sterilizer manufacturers, the quality of the weld can not be internally tested after production, requires 100 % ray inspection. Dissimilar steel welded joints, weld joints with a tendency to reheat cracks or a tendency to retard cracks must be tested for penetration).

2. Hydraulic test

The gas in the test vessel should be drained and filled with liquid (with water as the medium, the chloride ion content of the water should not exceed 25mg/L). During the test, the surface of the container should be kept dry; when the test vessel wall metal temperature When it is close to the temperature of the liquid, it can be slowly boosted to the design pressure. After confirming that there is no leakage, continue to increase the pressure to the specified test pressure (test pressure is 1.25 times the design pressure of the vessel). The holding time is generally not less than 30 min; To the design pressure, keep pressure for sufficient time to check and the pressure should remain constant during the inspection.

It is forbidden to not press the water pressure, only the pressure and the gas and water are mixed and pressed.

The above is a detailed description of the main body configuration and testing standards of the small sterilizer. If there is any other place that you don't understand, please feel free to consult our technicians at the powerful machinery factory in Zhucheng.
