rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...
The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...
Given the explosive growth of data, scalability and fault tolerance have become a fundamental challenge for data center network structures. Temperature in data centers significantly affects the failure ratio of high-speed network devices. Various types of air distribution schemes influence the temperature of network equipment differently, and the cooling cost in data centers dominates the overa...
We will discuss a novel non-contact removal technique of optical fiber coating in continuous and uninterrupted manner with hot air stream. We observed little degradation of the tensile strength of the optical fiber after removing the protective polymer coating and the mean breaking tensile strength of the stripped optical fiber using non-contact removal method was 5.1GPa. key words: non-contact...
The aim of the current work is to give a contribution to the study of the drying process of tomatoes through the synergy of the hot air and microwave technologies. The drying of tomatoes is a process commonly used to preserve the product and to prolong its shelf-life. In this paper, four experimental tests on the product under study, were carried out. Then, different drying diagrams were develo...
drying of green peas in a fluidized bed dryer (fbd) with inert particle, heated by combined sources of hot air and infrared (ir) radiation, has been experimentally and theoretically studied. for this purpose, an experimental set up was constructed. this setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. some infrared lamps were also pla...
more, syringes cannot be sterilized assembled or lubricated, and the syringe containers, whether multiple or single, must be so constructed that steam can freely penetrate to all surfaces of the syringe (Stewart, 1957; Darmady and Hughes, 1955). After sterilization a separate process is necessary to seal the containers before distribution to the user. Although syringes in their containers can b...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
The purpose of this paper is to analyse whether the presence of Hot Air trading jeopardizes the environmental target of an international environmental agreement. We argue that Hot Air can be used as an implicit side-payment mechanism to actually bring about higher environmental protection compared to the situation without the trade option. We point to the existence of a fundamental trade-off be...
A 16-year old girl experiencing palpitations underwent elective transthoracic echocardiographic examination at a nearby clinic, which showed a 3-cm balloon-like, cystic structure, with inhomogeneous content, adherent to the atrial septum and anchored above the anteroseptal commissure of the tricuspid valve without evidence of flow from the aorta to the right atrium (Figure 1 A). On examination,...
