HACCP in the production of bottled purified water application

Too high too low will affect the bactericidal oxidative effect. 1.5.3 automated filling between confined environment and the ozone sterilization of water purification or purification is not carried out mainly the air contacts the product will cause secondary pollution. 1.5.4 reverse osmosis membrane penetration of the quality and lifespan are important factors affecting water quality, regular cleaning and replacement of osmosis membranes will improve the quality of purified water. 1.5.5 Staff and inspection management system employee health knowledge and health status,[link widoczny dla zalogowanych], the operator easily contaminated or improper operation of the secondary pollution caused by products,[link widoczny dla zalogowanych], and strict management system and inspection system to ensure the quality of products entering the market. Control programs and measures 1.6 on the critical control point (CCP) to determine the appropriate control measures taken,[link widoczny dla zalogowanych], according to GB17323-1998 and GB17324-1998,[link widoczny dla zalogowanych], establish key values,[link widoczny dla zalogowanych], the key point of control measures and sampling and testing, and in 2003 5 4 months of production enterprises are verified in accordance with the HACCP program can be normal and effective manner. 1.6.1 barrel (cap) and equipment (pipes) disinfection carefully review all the barrels for damage before cleaning with NaOH according to certain proportion of the CLO and the cleaning and disinfection of crude washed carefully cleaned and disinfected and then re-washing machine, residual chlorine disinfectant lid <0.01ppm. All equipment (pipes) regularly strict cleaning and disinfecting. 1.6.2 Ozone disinfection operations staff seriously in accordance with the rules, the use of ozone concentration detector to monitor and maintain the ozone concentration in water 0.15-0.4ppm, in a timely manner operation of dry cleaning agent desiccant replacement and generator work. Earnestly instrumental record. 1.6.3 Filling filling workshop should be closed between the environment and set the air purifier, air cleanliness should reach 1000, Local 100 level. The air entering the plant to filter sterilization. Control of filling about 20% between the temperature. Open every day 30min before production UV Medical Forum in November 2004 Triple vessel line sterilization devices, in strict accordance with operating practices. Air fumigated once a week to keep dry and no water plant. Filling between the bacterial content of the air should be ~ <20efu / m, mold is 0. 1.6.4 reverse osmosis membrane permeability, high precision, high cost, in order to reduce membrane fouling and prolong the life of membrane, the membrane Prior to the preparation necessary to increase processing equipment in general, including multi-media filters, activated carbon adsorption and ion exchange column and so on. In the course of membrane surface to prevent and remove pollution, should pay attention to monitoring, 60% when the flux dropped to a 70%, must be cleaned, the membrane surface chemical cleaning needed on a regular basis, according to test results in a timely manner the two replacement Level permeable membrane. 1.6.5 employees once a year inspection and production staff health checks and health knowledge; production personnel to strictly observe good personal hygiene; into the shop before the need to disinfect hands and feet soaked; into filling a second to ask the staff to be changing. Self-test products to meet the requirements established laboratory batch testing of each batch of product sensory index, pH, conductivity, bacterial count, coliform and other indicators of the test, after passing the factory. Experimental methods 1.7 total number of colonies of various water samples, coliform, conductivity measurement based on GB17323-1998 and GB17324-1998. Plant selection in filling positions representative of 5 total number of colonies in the air as the detection point, the use of plate exposure method, 5min after the inspection, the number of 37 ℃ 48h culture postscript. Drums (cover) signed smear test with sterile cotton, bacterial count, coliform test according to GB4789-1995 {food hygiene inspection methods. 2 Results The results showed that after the implementation of HACCP empty barrel, cover, filling the air between the ozone sterilized water samples, the difference was significant P <0.01. After the implementation of HACCP in water samples after the two reverse osmosis and bottled water factory is lower than before the implementation of the conductivity, the difference was statistically significant P <0.01. Therefore, these aspects are critical control points. 3 to discuss the production of bottled purified water, the use of HACCP theory and method, analysis of risk factors to determine the critical control points and to take control measures. Luoyang City, four pure water production plant in the use of quality control of the management program, the product qualification rate reached 100%, the implementation of HACCP effectively improve the quality of bottled purified water, sanitation and safety.
