Clean-In-Place (CIP) of beverage, dairy and food processes is achieved by pre-rinsing, circulation of detergents, post rinsing, and sanitizing of process equipment designed for such automated cleaning. As processing plants have expanded production capacities, the size of the equipment has increased accordingly, creating a corresponding increase in the water volumes and sanitation compounds required to achieve proper cleaning and sanitation. The purpose of this paper is to identify the environmental factors impacted by the CIP process, further to offer areas of scrutiny that the processing facility staff may evaluate for improvement potential.

Poultry Processing

Conveyor belts are widely used in food handling areas, especially in poultry processing plants. Because they are in direct contact with food and it is a requirement of the Brazilian health authority, conveyor belts are required to be continuously cleaned with hot water under pressure. The use of water in this procedure has been questioned based on the hypothesis that water may further disseminate microorganisms but not effectively reduce the organic material on the surface. Moreover, reducing the use of water in processing may contribute to a reduction in costs and emission of effluents. However, no consistent evidence in support of removing water during conveyor belt cleaning has been reported. Therefore, the objective of the present study was to compare the bacterial counts on conveyor belts that were or were not continuously cleaned with hot water under pressure. Superficial samples from conveyor belts (cleaned or not cleaned) were collected at three different times during operation (T1, after the preoperational cleaning [5 a.m.]; T2, after the first work shift [4 p.m.]; and T3, after the second work shift [1:30 a.m.]) in a poultry meat processing facility, and the samples were subjected to mesophilic and enterobacterial counts. For Enterobacteriaceae, no significant differences were observed between the conveyor belts, independent of the time of sampling or the cleaning process. No significant differences were observed between the counts of mesophilic bacteria at the distinct times of sampling on the conveyor belt that had not been subjected to continuous cleaning with water at 45°C. When comparing similar periods of sampling, no significant differences were observed between the mesophilic counts obtained from the conveyor belts that were or were not subjected to continuous cleaning with water at 45°C. Continuous cleaning with water did not significantly reduce microorganism counts, suggesting the possibility of discarding this procedure in chicken processing.

Investigations of two chicken processing plants in The Netherlands have shown that large contamination with Campylobacter jejuni can exist on birds, equipment, hands of processing-line workers and in air samples from the processing facility. This contamination appeared only to be of intestinal origin. Intestinal contents of birds to be processed contained up to 107 C. jejuni per gram. Contamination of birds was reduced during scalding at 58°C, but this reduction was not always observed at 51.8°C. The number of C. jejuni on carcasses increased during defeathering and evisceration. Large numbers of C. jejuni were washed off the carcasses when a spinchiller was used. When air-cooling was employed, C. jejuni in some instances died off, probably due to drying. End-products from these chicken processing plants contained C. jejuni in 50% of carcasses and 75% of livers.

The Cost

Abstract Successful project management boils down to effectively and efficiently managing resources to meet the project's cost and schedule. The ability to manage project effectively becomes increasingly important to recover capital project expenditures in expiring Production Sharing Contracts (PSC) blocks. The longer the time needed for a project to complete, the higher the project capital and the lower the capital recovery. Referring to look back result of several major capital facility projects, the key challenge in meeting the project cost and schedule is related to procurement of long lead materials and key process equipment. In brown field blocks, there is an opportunity to perform reverse engineering by optimally utilizing the excess materials in the warehouse and idle/unused process equipment to solve the key challenges. As additional benefit, utilization of excess materials and idle process equipment will improve inventory management and capital stewardship, since the cost to relocate and modify the equipment are significantly lower than the cost of buying a new equipment. Field X Associated Gas Recovery Project (AGRP) provided an excellent case study of successful reverse engineering approach using excess material and idle equipment in design and construction of a new gas processing facility in brown field block. Field X AGRP is designed to recover and process associated gas from X field to be used as fuel gas for the gas turbines at the internal Power Generation Plant. However, based on lesson learned from similar opportunity in the past, the cost of construction and installation of a new gas processing facility using new construction materials and new process equipment is very high, which is uneconomic at the current oil price environment. Therefore, to make the project economic, the project team shall consider the utilization of available excess material in the warehouse and idle/unused equipment into design basis. Project team conducted assessment to several facilities across the concession area to gather equipment specification data of idle process equipment and the size of available excess materials. The gas processing facility design was reverse engineered to optimally utilize the idle process equipment and excess materials. The utilization of idle equipment and excess material in construction of the gas processing facility has successfully generated cost saving up to 5 times the project cost from avoiding purchase of new equipment and new construction materials. The project successfully recovered associated gas at the rate of 0.5 MMSCFD to be used as fuel to gas turbine and produced 60 BOPD condensate from gas-liquid separation process

Increasing demand diversity and volume in semiconductor industry (SI) have resulted in shorter product life cycles. This competitive environment, with high-mix low-volume production,requires sustainable production capacities that can be achieved by reducing unscheduled equipment breakdowns. The fault detection and classification (FDC) is a well-known approach, used in the SI, to improve and stabilize the production capacities. This approach models equipment as a single unit and uses sensors data to identify equipment failures against product and process drifts. Besides its successful deployment for years, recent increase in unscheduled equipment breakdown needs an improved methodology to ensure sustainable capacities. The analysis on equipment utilization, using data collected from a world reputed semiconductor manufacturer, shows that failure durations as well as number of repair actions in each failure have significantly increased. This is an evidence of misdiagnosis in the identification of failures and prediction of its likely causes. In this paper, we propose two lines of defense against unstable and reducing production capacities. First, equipment should be stopped only if it is suspected as a source for product and process drifts whereas second defense line focuses on more accurate identification of failures and detection of associated causes. The objective is to facilitate maintenance engineers for more accurate decisions about failures and repair actions, upon an equipment stoppage. In the proposed methodology, these two lines of defense are modeled as Bayesian network (BN) with unsupervised learning of structure using data collected from the variables (classified as symptoms) across production, process, equipment and maintenance databases. The proofs of concept demonstrate that contextual or statistical information other than FDC sensor signals, used as symptoms, provide reliable information (posterior probabilities) to find the source of product/process quality drifts, a.k.a. failure modes (FM), as well as potential failure and causes. The reliability and learning curves concludes that modeling equipment at module level than equipment offers 45% more accurate diagnosis. The said approach contributes in reducing not only the failure durations but also the number of repair actions that has resulted in recent increase in unstable production capacities and unscheduled equipment breakdowns.

Biosafety Level

Meat processing plants have been at the center of the SARS-CoV-2 pandemic. There are several factors that contribute to the persistence of SARS-CoV-2 in meat processing plants and one of the factors is the formation of a multi-species biofilm with virus. Biofilm can act as a reservoir in protecting, harboring, and dispersing SARS-CoV-2 from biofilm to the meat processing facility environment. We used Murine Hepatitis Virus (MHV) as a surrogate for SARS-CoV-2 virus and meat processing facility drain samples to develop mixed-species biofilms on commonly found materials in processing facilities (Stainless-Steel (SS), PVC and tiles). The results showed that MHV was able to integrate into the environmental biofilm and survived for a period of 5 days at 7C. There was no significate difference between the viral-environmental biofilm biovolumes developed on different materials SS, PVC, and tiles. There was a 2-fold increase in the virus-environmental biofilm biovolume when compared to environmental biofilm by itself. These results indicate a complex virus-environmental biofilm interaction which is providing enhanced protection for the survival of viral particles with the environmental biofilm community.

Definition Of

It was developed detergent–sanitizer «San active» for the sanitization of technology equipment for meat processing plants. Active substance of detergent–disinfectant «San active» is the TIME, STEAM, alkali, complexones and corrosion inhibitors. The importance of product development «San active» is that it combines two important features – a washing and disinfection.Previously it was established that means «San active» has good washing properties and shows high bactericidal effect on gram–positive and gram–negative microflora. Bactericidal action of «San active» at 14,8 times is more active compared with phenol, and in the presence in the environment the action of protein substances its activity decreases in 2,3 – 2,4 times. Remedy of 0,5% concentration has bactericidal effect on cells of S. aureus and E. faecalis, which are in the biofilm after 10 minutes of exposure. For the inactivation of cells E. coli and P. aeruginosa, which are in the biofilm, it is necessary that «San active» acted in a concentration not lower than 0,5% and less than 30 minutes. It asw established that the test culture of E. coli and S. aureus are not adapted to solutions of means «San active». A definition of corrosive action of detergent–disinfectant «San active» was designed for sanitary processing of technological equipment at meat processing industry. The degree of corrosion activity was determined by examining the corrosive action of solutions on medium plate, stainless steel, aluminum and galvanized iron, ie metal of construction for process equipment in meat production. It was established that working solutions of 1,0 – 2,0% detergent–disinfectant «San active» are practically not corrosive on stainless steel, because the corrosion was at times less than 200 –66 and 120 – 37 corrosion rate in times less than the acceptable norm. The rate of corrosion of galvanized iron under the influence of 1,0 – 2,0% solution of means «San active» ranged from 0,27 to 0,49 mg/m2 h, that in 2,0 – 5,4 times is higher compared to the effect on stainless steel and 44 – 24 times lower than normal. The rate of corrosion of similar detergent–disinfectants Hlorantoin, Virosan and Bioshaum to galvanized iron ranged from 0,44 to 0,49 mg/m2 h. This indicates the fact that the research variant of means «San active» for the magnitude and speed of corrosion on galvanized iron is not inferior to existing in Ukraine means. The corrosion value of aluminum for the actions of 1,0 – 2,0% solution of means «San active» was 2,2–3,7 times smaller compared to the norm, which refers to the aluminum and corrosion rate was to 1,0% solution of 2,86 mg/m2 h and 2,0% – 4,75 mg/m2 h that in 4,1 – 2,5 times less the standard value.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.
