Sanitary/hygienic Equipment Design.
2020Co-Authors: S. F. BilgiliAbstract:Proper cleaning and effective sanitation is an essential component of processing poultry, as it contributes significantly to the prevention of product contamination with microorganisms that cause food-borne disease and spoilage. Rapid expansion of production volume, increased further-processing and introduction of diverse ready-to-cook and ready-to-eat products, sophistication of the processing Equipment, implementation of HACCP and microbial finished-product standards, and, more importantly, expensive product recalls have necessitated greater control over the cleaning and sanitation process. A sanitary process should effectively protect raw and/or cooked products from physical (i.e., metal, plastic, bone, packaging materials etc.), chemical (residues of cleaning and disinfection chemicals, lubricants, coolants etc.), and biological (food-borne pathogens and/or their toxins) hazards. In spite of this, many hazards continue to find their way into the processing environment and ultimately into the finished products. Microorganisms are naturally introduced into the poultry processing environments in high numbers with the live birds and, when the conditions are suitable, from growth niches by actively multiplying within the system. It is generally accepted that processing Equipment should not be a direct or indirect source of microbial contamination. Many regulatory and advisory bodies have introduced hygienic Design and processing guidelines. This presentation will review the recently introduced sanitary processing Equipment Design principles and Equipment checklist by the American Meat Institute. A plant Designed, equipped, operated and maintained with internationally accepted hygienic and sanitary standards will produce safe and wholesome poultry products for the consumer.

optimal heat exchanger network synthesis with the detailed heat transfer Equipment Design
Computers & Chemical Engineering, 2007Co-Authors: Mauro A S S Ravagnani, Jose A CaballeroAbstract:This paper presents an optimisation model for the synthesis of heat exchanger networks (HEN) including the detailed Design of the Equipments formulated as a decomposition method. Shell and tube pressure drops and fouling are considered, as well as mechanical aspects, like shell and tube bundle diameters, internal and external diameter of tubes, number of tubes, number of baffles, number of shells, tube length, tube arrangement and the fluid allocation in the heat exchanger. The optimisation model is based on area, energy and pumping costs. The algorithm combines two distinct models, in a decomposition method, a mixed integer non-linear programming (MINLP) superstructure simultaneous optimisation model for the heat exchanger network synthesis considering stream splitting and a MINLP model for the detailed Equipment Design, following rigorously the standards of the TEMA. Two examples from the literature are used to test the algorithm developed, and the results confirm the achievement of the optimum HEN configuration with the detailed heat exchangers Design, following the TEMA standards.

Detailed Equipment Design in heat exchanger networks synthesis and optimisation
Applied Thermal Engineering, 2003Co-Authors: Mauro A S S Ravagnani, A.p Da Silva, Araújo AndradeAbstract:Abstract In heat exchanger network synthesis, important features like pressure drop and fouling effects are usually neglected. In this work a new methodology is proposed to include these effects in grassroots as in retrofit Designs. Heat exchangers are detailed Designed during the heat exchanger network synthesis. Pinch analysis is used to obtain the heat exchangers network with the maximum energy recovery, and a new systematic procedure is proposed to the identification and loop breaking. Bell–Delaware method for the shell side is used to Design the heat exchangers. An example of the literature was studied and the results show differences between heat exchangers, with and without the detailed Design, relative to heat transfer area, fouling and pressure drop. The great contribution of this work is that individual and global heat transfer coefficients are always calculated, in despite of the current literature, where these value are assumed in the Design step. Moreover, the methodology proposed to the heat exchangers Design assures the minor heat exchanger according to TEMA standards, contributing to the minimisation of the heat exchanger network global annual cost. Finely, the new heat exchanger network considering pressure drops and fouling effects presents values more realistic then those one neglecting the Equipment detailed Design.

URAI - Performance test Equipment Design of a 1 DOF joint torque sensor
2013 10th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2013Co-Authors: C. Park, G Jung, Hyun Min, B.i. KimAbstract:There are many reasons to use 1 DOF joint torque sensor at each joints of the robot manipulator. 1 DOF joint torque sensor is Designed to sensitively measure 1 DOF rotational torque induced by a BLDC motor and reduction train. Also it has to be insensitive to 5 DOF forces and moments which are not induced by a BLDC motor and reduction. But actually, the 1 DOF torque sensor has sensing error and it cannot be perfectly insensitive to the forces and moments not-induced by the motor. In this reason, a performance-test-Equipment has been Designed to measure the performance of the joint torque sensor mentioned above. In this paper, the research results will be introduced.

Office Equipment: Design, Indoor Air Emissions, and Pollution Prevention Opportunities
1995Co-Authors: Robert Hetes, Mary Moore, Coleen NortheimAbstract:The full report summarizes available information on office Equipment Design; indoor air emissions of organics, ozone, and particulates from office Equipment; and pollution prevention approaches for reducing these emissions. Since much of the existing emissions data from office Equipment are proprietary and not available in the general literature, they are not included in the report. The report covers (1) dry and wet process photoimaging machines (copiers, printers, and faxes); (2) spirit duplicators; (3) mimeograph machines; (4) digital duplicators; (5) diazo (blueprint) machines; (6) computers and computer terminals; (7) impact matrix printers; and (8) other Equipment types. Office Equipment emits indoor air pollutants as a result of Equipment operation, offgassing from components, or episodic releases related to catastrophic failure of a unit. For Equipment that does not use supplies (e.g., video display terminals) emissions are primarily from offgassing of residual organics. Increased levels of ozone, total volatile organic compounds, and particulates have been observed in the presence of operating Equipment and have been associated with complaints by exposed workers. Published emission rates, IAQ impacts, and potential pollution prevention solutions associated with the Equipment types are discussed in the full report. This Project Summary was developed by EPA’s Air and Energy Engineering Research Laboratory, Research Triangle Park, NC, to announce key findings of the research project that is fully Office Equipment: Design, Indoor Air Emissions, and Pollution Prevention Opportunities
