5.1 Productivity test
The productivity test of the filling machine should be carried out under the condition that the filling pressure and other filling test items are qualified. The test time should not be less than 10 minutes.
5.2 Filling accuracy test
5 minutes after the start of the test, continuously cut 100 bottles of beverages that have been filled and sealed. After 5 minutes, continuously cut 100 bottles, a total of 200 bottles, and then measure the distance h from the liquid surface to the bottle mouth of the beverage bottle by bottle, and then calculate the average value of the distance from the liquid surface to the bottle mouth according to formula (1): h: mm
The liquid level error △z of each bottle is calculated according to formula (2): Ai=h,-hmm
The filling accuracy pass rate is calculated according to formula (3): Filling accuracy pass rate = (1 - number of unqualified bottles) × 100% 200
5.3 Beverage loss rate test
·（2）
·（3）
The beverage loss rate test is carried out on the total number of bottles tested continuously. The total number of bottles tested continuously should be greater than 50 times the number of filling valve heads of the filling machine. The calculation method is according to formula (4)):
5.4 Bottle loss rate test
Beverage loss rate = Lost beverage volume Lost beverage volume × 100… Lost beverage volume
Count the number of lost bottles and the total number of bottles under normal filling conditions. The total number of bottles is continuously counted as 50 times the number of filling valve heads, and the bottle damage rate is calculated according to formula (5): Number of damaged bottles × 100%
Bottle damage rate =
Total number of bottles
5.5 Sealing qualified rate test
(5)
5 minutes after the start of the test, continuously cut 200 bottles of beverages that have completed filling and sealing, and soak them in warm water at 45-65℃ for 5 minutes. There should be no bubbling phenomenon. The calculation method is according to formula (6): Sealing qualified rate = Number of bottles that have been directly bubbled ± Number of bottles with damaged caps × 100%200
5.6 Filling valve test
Low-pressure leakage test
The filling valve is subjected to a 0.06MPa water pressure test and the pressure is maintained for 3 minutes. There is no water dripping from the valve mouth. b. Maximum filling pressure test
The filling valve is subjected to a water pressure test of 1.1 times the filling pressure, and the pressure is maintained for 5 minutes. There is no water leakage at the valve port* (6)
5.7·Energy consumption test
