The LTR process include the following data:

The low temp rendering process is the gentlest method of treating animal by products and originates from fishmeal processing.

• The material is scanned for steel scrap in a metal detector, pre breaker and fine pre breaker the material into small pieces about 25mm.
• The material is then cooked in a continuous pre-heater/cooker at temp. 95 deg. C
• The cooked material is pressed in a slow rotating twin screw press to separate press cake and press water which is separated to stick water and tallow in a 3- phase decanter and purifier separator. The solid are dried to meat and bone meal in a disc dryer and tallow is purified (polished), and can be further vacuum dried to remove all traces of water. The meal is cooled and ground in a hammer mill for storage.
• The greatest advantage of the gentle Low Temp Rendering process is that the chicken meal and oil is of high quality if fresh raw material.
• Another advantage is that all components in this plant has low wear, so that the lifetime of the plant can be 15-20 years without major overhaul.

Note that the fast rotating decanter and separator have higher wear and will need normal servicing every 1-2 years.

• The low temp process allow the use of WHE – waste heat evaporator to save up to 50% of the steam consumption (which is not possible with the HTR – high temp process) to get a steam consumption 550-600 kg steam/ 1 ton raw material.
