Definition of drying
Importance of drying
Difference between drying and evaporation
Drying is defined as removal of the liquid from a material by application of heat & is accomplished by transfer of a liquid from the surface into an unsaturated vapor phase .
Drying is the final removal of water from material (usually by heat)
Drying is commonly the last stage in a manufacture process
Non-thermal drying
1- As Squeezing wetted sponge
2- Adsorption by desiccant (desiccation)
3- Extraction.
Preservation of drug products
Preparation of bulk drugs
Improved handling
Improved characteristics
Equipments
Drying is necessary in order to avoid deterioration. A few examples are…
--blood products, tissues… undergo microbial growth
--effervescent tablets, synthetic & semi synthetic drugs undergo…. chemical decomposition.
Pharmaceutical Dryers. Dryers are used in a variety of industries, such as the food processing, pharmaceutical, paper, pollution control and agricultural sectors. ... Direct dryers convectively heat a product through direct contact with heated air, gas or a combusted gas product.

Refractance window drying is a novel
fourth-generation drying technology that is employed to dry heat-sensitive products like juices and purees to retain the product colour, aroma, antioxidant compounds, and nutritional properties. it is a thin film drying system having high heat and mass transfer rates that speed up the rate of drying at a comparatively lower temperature.In this technology, drying of product is done using thin, transparent infrared film which eventually forms a "window" for drying, it assures very low-temperature drying with
rapidity, with all modes of heat transfer.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
2. PRINCIPLE
• In vacuum dryer material is dried by the
application of vacuum
• When vacuum is applied the pressure is
lowered so that water boils at a low
temperature
• Hence water evaporates faster
• The rate of heat transfer becomes efficient
• So that drying rate substantially enhances
3. CONSTRUCTION
• Heavy jacketed vessel – cast iron
• It can withstand high vacuum within the oven
and steam pressure in the jacket
• The enclosed space is divided in to a number
of portions by means of 20 hollow shelves
which are a part of jacket
• These shelf's provide large larger surface area
– 45-50 metre square
4. • Over the shelfs metal trays are placed
• Oven door is tightly sealed
• Oven is connected to a condenser
• Condenser connected to a vacuum pump
5. WORKING
• The materials to be dried is spread on trays
• The trays are placed on the shelves
• Vacuum is applied so pressure will be
decreases up to 30-60 kilopascals. Because of
that boiling point of the liquid decreases .so
that the liquid will boils at low temperature
than its BP.
6. WORKING
• After applying vacuum ,door is closed firmly
• Steam or hot air is introduced in to the hollow
space of jacket and shelves
• Heat transfer takes place by conduction
7. WORKING
• So that water will be evaporated from the
material at 25-30 °C because of the lowering
of the BP
• Water vapor passes in to the condenser where
condensation takes place.
• At the end of the drying vacuum line is
disconnected
• The dreid material is collected from the trays
8. USES
• Useful for drying heat sensitive materials
which undergo decomposition
• Dusty and hygroscopic materials
• Drugs containing toxic solvents can be
removed and it can be collected in to closed
container
9. ADVANTAGES
• Large surface area for heat transfer
• Handling of the material ,trays and equipment
is eazy
• Electrically heated hollow shelves can also be
used
