Identify ingredients, the steps of the rendering process, specialized equipment, and associated hazards.
The rendering industry is vital to the sustainability of the animal feed industry. It provides the utilization of products that would be otherwise unused as feedstuffs. Common rendered ingredients include: feather meal, poultry meal, meat and bone meal, blood meal, spray dried animal plasma, fish meal, poultry fat, beef tallow, choice white grease, and yellow grease.
The rendering process includes receiving feedstuffs and by-products, sorting them into similar sizes, and press cooking them to separate fats prior to grinding. Of these steps, the cooking process is most pivotal.
Specific equipment used in rendering includes sizing equipment, cookers, a feed press, and hammer mills.
Potential feed safety hazards include physical products, cleaning chemicals, and potential microbial risks inside slaughter or rendering facilities. The Rendering Code of Practice minimizes these risks in a preventative manner so that rendered ingredients pose a low animal feed or human food safety risk.
