Efforts of Microwave and Infrared Radiation in Chemical Pulping pay off

Pulping  is a procedure that separates fibrous material and cellulose from wood or other crude material as a prelude to papermaking. The reason for pulping is to free cellulose strands from other chemicals and polluting influences in the wood (or different fibrous source). Before wood can be pulped, it must experience debarking i.e. expelling bark mechanically or hydraulically and then sending the debarked wood into a chipper to cut them into small pieces ready for pulping. Pulping can be done by three processes – Mechanical  – Using machines like revolving disks to prepare the pulp for paper making. Chemica l – wood chips are cooked in a combination of chemical solution to remove cellulose or lignin from the wood. Semi-mechanical  – a blend of mechanical and chemical. Here we understand the process of  Chemical Pulping  in detail. As known it is a method of converting the wooden chips into damp pulp for paper making or processing, by cooking the wooden chips in a chemical sol

How do you make Dairy products fit for consumption?

Dairy products are basically products made from containing milk of mammals, which include food products like yoghurt, cheeses and butter among others. These products have been a part of staple food in many countries and used in traditional cuisines as well. Rates of dairy consumption vary widely worldwide. The consumption can be as high as 150kg per capita and also under 30 kg per capita in some countries. Milk is a valuable nutritious food that has a short shelf-life and requires careful handling. Milk is highly perishable because it is an excellent medium for the growth of  microorganisms  – particularly bacterial pathogens – that can cause spoilage and diseases if consumed without precautions. Hence, milk processing, this allows the preservation of milk for days, weeks or months and helps to reduce food-borne illness. The usable life of milk can be extended for several days through techniques such as – Clarification –  particles with dense solids are separated from continuous
