Is your screw press oil yield not what you expect or require?
We can help!
With more than 30 years of experience of working with screw presses for oilseed extraction, we identify both process-related issues and mechanical problems that lead to reduced oil yields and high solids content in the crude oil. We can also propose improvements to the OEM's design to boost screw press performance.
The extraction efficiency of a screw press is dependent on several factors. Proper preparation of the raw material is one important aspect. Each raw material must undergo size and moisture reduction to maximize throughput and oil yield. Raw materials with a high protein content also require a cooking process prior to screw pressing. Moisture and raw protein reduce the friction coefficient in the feedstock, which prevents the oil cells from being masticated, and the solid material from being compressed. Mastication frees the bound oil and compression separates the vegetable oil from the solid material. Preparation also plays a major role in screw press efficiency.
Higher-Quality, Better Yield
Another important aspect of screw press efficiency is the design, material, and construction of parts used in a screw press. Inexpensive parts made from inferior materials have a shorter service life, which leads to frequent replacement, higher scrap, and lost production hours. Maintaining a screw press in a steady-state for as long as possible maximizes its efficiency, reduces operating expenses, and increases margins.
