The experts in innovative food processing machinery


The rendering industry plays an essential role in the food processing chain. Between 37 and 49% of the live animal weight is removed during slaughtering and further processing, with an even greater percentage lost during fish processing compared to beef cattle, sheep, pork or poultry. The remaining portion of inedible protein, discarded viscera, fat, oil, feathers and other materials must be either converted or disposed. Disposal would translate into more crowded landfills and increased carbon emissions from resulting decomposition.

Instead, the rendering industry converts these into more than 20 billion pounds of valuable byproducts each year, namely high-quality fats and proteins, primarily used in the animal feed and oleo chemical industries. One research paper named the meat and bone meal (MBM) produced as “especially strategic feed ingredients.” MBM provides an economical source of protein and phosphorus for animals, which spares this country from mining extra phosphorus; eliminates the need for millions of more acres of soybean and corn crops to make up the caloric deficit, and in addition supplies us with bio-security by destroying potentially pathogenic viruses, bacteria and microorganisms.

Lyco offers an efficient and effective way to separate rendering oil and fats from cracklings, as they discharge from batch or continuous cookers. The Lyco Sealed Drum Separators remove more solids, which relieves stress on centrifuges. In addition, the separator eliminates perc pans, which helps lower maintenance costs and improves plant safety. Lyco employs the use of efficient wedge-wire screens to remove fines down to .020-inches. The entire system completes the process within a smaller footprint compared to other separators or screening systems. Our sealed drum separator construction contains odors, aids in temperature control and improves liquid recovery.

Most rendering screen cylinders are made with rolled, welded and re-rolled running rings all of which eventually fail. Except for gross neglect Lyco has NEVER had a running ring failure since the early 1990’s because we use cast stainless steel running rings and have made over 600 screens using that design.
