It is a fine powder high in calcium carbonate which is popularly used in animal feeds, pharmaceuticals, food supplements, and even cosmetics. Recycling these shells would therefore lead to less environmental wastage in industry and profit from a good by-product, turning waste into wealth.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Complete_Manufacturing_Process_of_Egg_Shell_Powder\"><\/span><b>Complete Manufacturing Process of Egg Shell Powder<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The different steps undertaken in the manufacturing process of egg shell powder go into ensuring a high standard of purity, quality, and even safety. Here is the entire detailed stepwise process:\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Collection_and_Washing\"><\/span><b>1. Collection and Washing\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The first process is the collection of the raw egg shells at poultry farms or any kind of processing unit. The shells are usually dirty and carry some egg white residues, dirt, and microbes. Washing them properly in water with mild detergents sometimes gets rid of the contaminants, making the shells ready for the subsequent stages.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Drying\"><\/span><b>2. Drying\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Immediately after washing, you dry the wet shells to reduce their moisture content. You can dry them either by using natural sun drying or by using industrial dryers like tray dryers or rotary dryers. Proper drying will prevent growth of microbes and facilitate grinding.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Grinding\"><\/span><b>3. Grinding<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Dried, then the eggshells are fed into grinding machines which crush them into small-sized powder. The quality of the grinding machine will affect the size as well as the uniformity of the egg shell powder. It usually employs hammer mills, ball mills, or pulverizers.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"_4_Sieving\"><\/span><b>\u00a04. Sieving\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Upon grinding, the powder is passed through sieves for the separation of coarse particles and fine ones. The sieving process ensures that the egg shell powder conforms to the desired specifications in particle size.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Ownership\"><\/span><b>5. Ownership\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>You would use moisture-proof packaging materials, like polyethylene bags or multilayer laminates, for the final packaging of egg shell powder, thereby ensuring the quality of the powder during its storage and transport.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Machinery_Used_in_Egg_Shell_Powder_Production_with_Specifications\"><\/span><b>Machinery Used in Egg Shell Powder Production with Specifications<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The choice of machines to use is very important with respect to the efficiency and quality of production of egg shell powder.
