Determination of production line efficiency
After the machine is started and the production is normal, take the number of finished products (cans) produced continuously for 2 hours at the finished product export position, and calculate the production line efficiency according to formula (1) and formula (2). n
(1)
Where:-
Production line efficiency, %
QB/T 2370—1998
Q—Number of finished products produced continuously for 2 hours, cans; F-Nominal production capacity of the production line, cans/h; T——Effective time, h.
Effective time T is the test time (2 h) minus the sum of all downtimes of any machine not caused by the machine's own failure during the test time, t. That is:
T=2-Zt
Where: T-
Effective time, h;
-The sum of all downtimes of each machine not caused by the machine's own failure, h. Mt
6.2 Determination of filling capacity qualified rate
. (2)
During normal production, first continuously extract 100 samples of finished filling and capping on the conveyor belt at the outlet of the filling machine, and then continuously extract 100 cans after 10 minutes, a total of 200 cans of samples, and use any method in 5.1.2 to inspect, and take out qualified samples and calculate according to formula (3): m
Filling capacity qualified rate, %,
Number of qualified samples after inspection, cans. www.bzxz.net
6.3 Determination of capping qualified rate

During normal production, randomly take samples at the outlet of the capping machine that are 5 times the number of capping heads, immerse them in hot water at 50-60℃ for 5 minutes, and the cans are qualified if there is no bubble overflow, and calculate according to formula (4). m×i00
Where: S—capping qualified rate, %;
m,—capping qualified samples,;
m2 Capping test samples, cans.
6.4 Determination of can damage rate
Record the number of damaged cans detected in each process and the number of cans used in production during the test time, and calculate according to formula (5). ×100
Where: K-
Can damage rate, %;
Total number of damaged seams detected in each process, cans; Number of cans used in production, cans.
Determination of liquid loss rate of filling materials
The liquid uptake rate of filling materials is calculated according to formula (6): L= [1 - 0. 355(Q+N2)]×100
Wherein: L
Liquid loss rate, %;
-Number of finished products within the test time, cans;
k---Filling coefficient of unqualified products, 0.7～0.9; N2——Number of unqualified products that can be recovered within the test time, cans; G——Amount of beer (beverage) used within the test time, L. Note: Formula (6) is used for 355mL cans. 7 Inspection rules
