What is meat rendering??

Rendering is a process that converts waste / by-products from fish, pork, cattle, and poultry processing industries into stable, usable materials. Materials like meat and bone meal, meat meal, poultry meal, blood meal, fish meal and animal fats and oils. These animal by-products are very useful as feed ingredients for livestock, poultry, pet food, aquaculture, and regular animal feed.

Q: Meat rendering processes

The Raw material, whether it is from pork, cow, or fish, is collected and accumulated in storage tanks. When ready to be processed, the product is sized down through a crusher or transported directly for heating. Traditionally this is done in a cooker which heats the product to a temperature where the bacteria are killed, and the liquids and fats are suspended from the solids. Afterwards the product is compressed in a screw press which squeeze out the main part of water and fats. The remaining solids referred to as the press cake is then dried and milled to a flour. The liquids are separated in decanter to get the water and oil. The oil is cleaned, and the water is used in the process again.

Excellent wearing qualities

JS provides solutions for transportation, grinding, and handling of the raw material within meat rendering processes. Our equipment handles by-products from the fish, poultry and cattle processing industry.

By-products which are not intended for human consumption, are rendered / transformed into stable, valuable and useful materials like oils, proteins and minerals. The process covers drying the material and separating the fat from the bone and protein.

JS Proputec has extensive experience in designing and manufacturing both standard and customized solutions, fulfilling specific needs within the meat rendering industry.

Unloading of truck

For unloading of trucks with carcasses or animal by-products to the meat rendering plant JS Proputec manufactures customized unloading bins to fit the exact space where it is needed.

The unloading bin is often combined with a lamella pump or a screw conveyor for further transportation.

Raw material transportation

The JS lamella Pump is, due to its tough and robust design, the ideal choice for moving a high viscosity media like fish and animal by-product over long distances.

The pump will often in this application need a positive infeed from a JS Infeed hopper, which is specifically designed to last in this high demanding application.

For short distances JS also manufacture high quality screw conveyors.

Feeding of cookers

After the reception bins, the lamella pump is the best choice for transporting the raw material over long distances to the cooker.

It is also the most flexible solution as you can switch between which cookers to feed from each pump.

Transportation after pre-cookers

For transportation of cooked animal by-products after cooker the JS HP Lamella Pump is the optimal choice as it is better at handling lower viscosity products.

The pump can be equipped with the JS Easy Clean Solutions which makes it much easier to open the pump if a foreign object gets stuck.
