Maximum yields with REINARTZ

from biomass

You have the raw material, we have the know-how. Thanks to the leading REINARTZ technology, green waste, leaves, wood residues, biogenic residues or co-products from the food industry become efficient sources of energy. Our dewatering, drying and separation processes work for you with a high degree of efficiency. Sustainable, comprehensive, profitable.

High-quality vegetable oils and fats

For decades, REINARTZ has been standing for the constant optimisation of leading cold pressing processes. Because our engineers and designers know: There is always a still better value to achieve! The efficient and gentle extraction of first-class vegetable oils and valuable fats is associated with the name REINARTZ in the food and cosmetics industries worldwide.

Nutritious plant proteins

Protein-rich press cake is a co-product of our cold-pressing processes, for example from rapeseed, sunflowers or soy. As a food rich in vitamins and proteins it is requested by the animal feed industry. Especially if it comes from REINARTZ. Because of our many years of experience, we always know how to create optimal conditions for the maximum preservation of valuable proteins in the various pressing processes. The press cakes can be processed directly or used for further extraction of the pure proteins.

Natural insect proteins

Insect larvae represent the sustainable form of a protein-rich diet. The animal feed industry uses insect meal from dried and defatted larvae of the black soldier fly, which has a protein content of over 60 percent. The demand for insect proteins is increasing rapidly. With our many years of know-how, we offer our customers the complete program for effective production of insect protein, from the customised system planning to commissioning and monitoring.
