Embodiment Construction

[0020] As shown in Figure 1, the quantitative evaluation method of the disinfection effect of the external surface of the aseptic filling equipment of the present invention consists of the following steps:

[0021] A. Attach the test piece connected with standard microorganisms to the external surface of the equipment to be tested:

[0022] B. Run the disinfection program for the external surface of the equipment;

[0023] C. Collect the residual standard microorganisms on the test piece, cultivate and calculate, and obtain the value of the residual standard microorganisms;

[0024] D. Compare the value of the standard microbial residual amount with the original amount value to obtain the evaluation result.

[0025] In the above step A, the following operations need to be completed:

[0026] 1) Grinding treatment, cleaning and disinfection of the test piece: cut the metal piece with a thickness of 0.1-0.5mm into a test piece with a specification of 25-35mm×55-65mm; Repeated...

Abstract

The invention relates to a quantitative sterilization effect evaluation method of outer surface of an aseptic filling equipment of beer or other beverages. The quantitative evaluation method comprises the following steps of: (1) adhering a detection slice loaded with a standard microorganism on the outer surface of a detected equipment; (2) sterilizing the outer surface of the equipment; (3) sampling the residual standard microorganism on the detection slice, culturing and calculating to obtain residual value of the standard microorganism; and (4) comparing the residual value of the standard microorganism and the original value to obtain the evaluation result. The invention can rapidly and quantitatively evaluate the sterilization effect of the outer surface of an aseptic filling equipment, and judge whether the sterilization effect in various positions of the sterilization system coverage region. The invention can also be used as a comparative analysis and evaluation means of the sterilization effects of the outer surface of the aseptic filling equipment using different sterilization methods (containing different disinfectants).

Description

technical field [0001] The invention relates to a quantitative evaluation method for the disinfection effect of the outer surface of aseptic filling equipment for beer or other beverages. Background technique [0002] The disinfection effect of the beer or other beverage filling area, especially the external surface of the aseptic cold filling equipment, is directly related to whether there is a risk of secondary pollution in the filling area. For this reason, the manufacturer installed an automatic disinfection system for the external surface of the filling equipment, and set up a corresponding disinfection program to disinfect the external surface of the equipment with a disinfectant. [0003] For the evaluation of the disinfection effect of the external surface of the equipment in the beer or other beverage filling area, there is currently no quantitative analysis method to evaluate the effect, especially the uniformity of the area covered by the disinfection system and d...
