Experimental results from the transient drying of sheets of polyester in an infrared (IR) dryer were used to derive a performance model. Separate drying experiments were done using sheets of material of various densities and thicknesses. The formulations expressed the core temperature of the web to the surface temperature of the web as a function of the residency time in the dryer and the elect...
Process analytical technology (PAT)-tools were used to monitor freeze-drying of Bacille Calmette-Guérin (BCG) at pilot and production scale. Among the evaluated PAT-tools, there is the novel use of the vacuum valve open/close frequency for determining the endpoint of primary drying at production scale. The duration of primary drying, the BCG survival rate, and the residual moisture content (RMC...
In this paper, a sliding mode control with a proportional integral (PI) sliding surface applied to the hybrid tunnel dryer has been assessed through simulations. A dynamic model of the process was developed specifically for this purpose. The pseudo-bond graph methodology was used in modelling the system, such methodology was very suitable for this thermal process and permits us to establish a m...
Conservation of agricultural crops and minimization of grain losses is challenging issue in the present scenario. Effective use of thermal energy for drying of paddy and other cereals for maintaining proper quality is the quality drying process. Natural convection grain dryer is quite suitable for under developed and developing countries like India where rural electrification and advanced dryin...
Recently, washer-dryer machines with slanted drums have become popular in Japan. We measured and analyzed posture while using such machines with three-dimensional motion capture measuring devices. Subjective Kansei and usability questionnaires were also used. After the measurements, working postures were analyzed with a human kinematic model (3D SSPP). Three types of machines were used for the ...
An intermittent noise that occurs around 30 seconds after compressor start-up has been disturbing customers of many domestic refrigerator manufacturers over the past 10 years. This noise is very similar to that produced by popcorn popping, being referred to as popping noise. The most probable cause of this strange and unpleasant noise is thought to be CIS (Condensation Induced Shock). The aim o...
spray drying is one of the most important processes applied in the industry. the equipment used in this process evaporates water in a very short time and so, need a lot of energy. in this work, we used microsoft excel as an analysis tool for the optimization of fuel usage in this dryer. we have described the process in terms of thermodynamic calculations and mass and heat balance equations. our...
AIMS To compare an ultra-rapid hand dryer against warm air dryers, with regard to: (A) bacterial transfer after drying and (B) the impact on bacterial numbers of rubbing hands during dryer use. METHODS AND RESULTS The Airblade™ dryer (Dyson Ltd) uses two air 'knives' to strip water from still hands, whereas conventional dryers use warm air to evaporate moisture whilst hands are rubbed togethe...
Abstract—Present study focused on the utilization of solar energy by the help of photovoltaic greenhouse solar dryer under forced mode. A single slope photovoltaic greenhouse solar dryer has been proposed and thermal modelling has been developed. Various parameters have been calculated by thermal modelling such as greenhouse room temperature, cell temperature, crop temperature and air temperatu...
