Glass bottles may have stress during manufacturing and processing for some reasons, which may lead to the bursting of glass bottles in high temperature sterilization, filling and other finished product processing.

The phenomenon of stress during glass production has significant consequences on the quality of the glass. This has the effect of causing fragility in the samples. It is therefore essential to control this risk.

CanNeed-PLT-300 Polarization Tester is used to measure the stress of glass bottles.which is developed to highlight various stress defects on glass bottles. It can meet the qualitative testing or quantitative testing, by using the birefringence phenomenon produced by light irradiation to glass bottles to calculate the optical range difference, so as to directly calculate the stress value and stress level.

CanNeed-BCT-100 CO2 tester and Pressure Tester is for measuring the CO2 content in carbonated beverages filled in glass and PET bottles or cans. It is designed according to ASBC Theory of American Society of Brewing Chemists, corresponding to “GB/T 4928 – 2001 Brewing Analysis Methods” and “GB/T 10792 – 1995 Carbonated Beverage Analysis Methods”. Therefore, the machine is widely used by Quality and Technical Supervision Bureau and beverage enterprises.  

With reference to method of ASBC American Society of Brewing Chemists, CanNeed-AS-400D auto shaker CO2 calculator is designed and complied with national standards GB/T 4928－2001 Method for Analysis of Beer and GB/T 10792-1995 Carbonated Soft Drinks (Soda). It is well adopted by many brewery enterprises, beverage enterprises and quality & technical supervision institutions.

CanNeed-PPT-200 Preform Profile Tester is suitable to measure preforms of various sizes to execute fast replacement of machinery in production process.

Measuring Process:

Bottle packaging is one of the common packaging forms of food, beverage and drugs. The torque value of opening and closing is one of the key controlling parameters on production line or offline. The appropriate torque value has a great influence on the transportation and final consumption of the products. It is one of the key product indicators which needs to be controlled by enterprises.

CanNeed-ATT-Line-1000 Automatic Torque Tester is the ideal instrument to do this test. It can be placed maximum 12 samples, then automatically sampling by conveyor belt. The sample will be measured automatically once arrived at the measurement station and avoid the influence of human factors.

The “CanNeed-Inpack 3000 CO2 Tester and Pressure Tester” is used to measure the CO2 content in carbonated beverages filled in glass and PET bottles and cans. It is corresponding to “GB/T 4928 – 2001 Brewing Analysis Methods” and “GB/T 10792 – 1995 Carbonated Beverage Analysis Methods”. Therefore, the machine is widely used by Quality and Technical Supervision Bureau and beverage enterprises.

CanNeed-Inpack 3000 can measure the total pressure in brewery or beverage. Applied with temperature measurement, the CO2 content is determined by means of the CO2 slide rule or temperature/pressure relationship charts. It is applicable to the bottles or cans with different sizes.

CanNeed-TPO-100 Total Package Oxygen Analyzer adopts the world’s most leading optical sensor, which is quick and exact in sensing and responding, and requires only a few samples to finish the test. It is also featured with personalized design, push button startup, automatic puncturing and auto measuring.

Push button startup, directly displaying the total content of O2 and CO2 in the LCD screen, clear display of test data of the dissolved O2, bottle neck space and CO2 content. No need of complicated calculation.
