Drying in Pharmaceutical Industries


Drying plays vital role of life saver to many industrial process then how it cannot be mentioned for the industry which help many living things to save their life and keep them healthy. Yes, you got it right, in this article I will try to jot down the role and importance of drying as process in pharmaceutical industries.  All lifesaving drugs processed in the pharmaceutical industries needs to go through multiple drying stages as the any microbial infection, thermal decomposition, contamination or unremoved organic solvent may damage the quality of product, this might result in fatal effect on the life of consumer. This industry is very quality intensive industry hence all the process equipment and dyers required must be of high quality and meet the industry standard.
At Kerone, we are having immense experience in handling such need for such high quality and precise processing industries, with our custom designed and built dryers and process equipment.
Pharmaceutical dryers should be of high standard and sophisticated with varying temperature range and types of either batch or continuous type. Basically there are three subsequent stages in non-liquid drugs 1) Synthesis of intermediate products 2) Final synthesis 3) drug dosage forms and these stages require drying and/or preheating before or after the process.  
Substances dried in pharmaceutical industries are classified in three groups: 1) Granular material 2) Pastelike Material 3) Solution and suspensions. Special type of dryer is required for drying of these type of material hence it becomes very critical to identify the type of material first and then the type of dryer required for it. Selecting appropriate dryer is necessary for the success of process, below is the small classification:
  1. Granular Material: Convective dryers of variant tray, ban, fluid bed, flash, or any other custom design dryers. Also, vacuum dryers and paddle dryers are too suitable.
  2. Pastelike Material: Tray dryer, band dryers, spin-flash dryer and spray dryers are suitable.
  3. Solution and suspensions: Freeze-dried 
Further selection of dryer is based on following components:
  • Size of Particle
  • Thermal Property
  • Heat sensitivity
  • Moisture contains
  • Absorption rate
  • Sorptive properties and etc.

Different Types of Sterilization Process

  Sterilization can be accomplished by an amalgamation of heat, chemicals, irradiation, high pressure and filtration such as steam under pressure, dry heat, ultraviolet radiation, gas vapour sterilants, chlorine dioxide gas etc. Successful sterilization strategies are necessary for working in a lab and negligence of this could lead to severe consequences, it could unexpectedly cost a life. So what are the more frequently utilized methods of sterilization in the laboratory, and how do they work? The Sterilization is conveyed out by the methods according to requirement. The methods are: 1. Moist Heat Sterilization 2. Dry Heat Sterilization 3. Gas Sterilization and Others. Moist Heat Sterilization:  Moderate pressure is utilized in steam sterilization. Steam is utilized under pressure as a means of accomplishing an elevated temperature. It is dominant to confirm the accurate quality of steam is utilized in order to keep away the problems which follow, superheating of the steam, f...

Electromagnetic Energy in Food Processing

  The use of electromagnetic energy in food processing is considered with respect to food safety, nutritional quality, and organoleptic quality. The results of nonionizing radiation sources such as microwave and radio-frequency energy and ionizing radiate on sources. Nonionizing microwave energy sources are more and more used in home and industrial food processing and are well-accepted by the end users. But, even though new-fangled Food and Drug Administration approval of low and intermediate ionizing radiation dose levels for grains and further plants products. Microwave  and  radio frequency  energy are allotments of the electromagnetic spectrum that can redeem heat to foods selectively and systematically. Explicitly, microwaves interrelate with water in foods to heat preponderant those allotments that are wet. End users are usual with microwave ovens as household appliances used to warm and cook foods, defrost frozen foods, and pop popcorn. On an industrial scale,...

Industrial Heating System for Biscuit and Cookies Baking

Biscuits and cookies have been part of our life since long time, we all love and like to eat some or other type of biscuits or cookies due its brand, taste, health benefits and many other reasons. One thing that we all love about them is their crispness, crispy and crunchy biscuits have always been first choice as biscuit and cookie lover. If it’s not crunchy then as consumer we never felt like we have some good biscuit or cookie and some it’s not baked properly, even if it’s over crunched and browned lots then also it gives taste like its burned while baking. Hence baking of biscuits and cookies become very important and critical for them to taste at best. Baking is one of very critical process in biscuits and cookies manufacturing plants, and it’s defined in food processing as process to heat the food to reduce its moisture completely and give them sustainable solid structure, so that they can last for longer time duration. In short the baking is kind of cooking food by the manne...
