Food & Additives

Wheat, rice, and corn. They are the staple foods of the world. But they each have many other uses. Clean energy and new materials can be made from the extracts and powders produced by the Szego Mill. And beyond these staples, a huge range of natural edible products can be processed more efficiently by replacing or augmenting other technologies with the Szego Mill.

Even the discarded grain and mash from craft breweries can be re-used for nutritional supplements after processing in the Szego Mill.

Our customers benefit from reduced waste and increased yield by using the more affordable, more efficient Szego Mill and our innovative, patented technologies.

Generalised Integration Of Solid Waste Treatment Practices To Enhance Methane Productivity, Generate Suspension Fertiliser, And Upgrade Biogas

This paper was made available by our associates and is not authored by Szego Materials Engineering. We offer it to our customers for relevance to processes using the Szego Mill.

This paper presents a general solution of how to link together the treatment of different solid waste: excess sludge, wastes glycerol or fishery residues and waste ash. The aim of the solution is to enhance biogas production and to produce an organic–mineral suspension fertiliser. The enhancement of biogas productivity is achieved by adding waste glycerol from biofuel plants or fish residues from fish farming and fishing industries into anaerobic reactors of wastewater treatment plants. The enhancement of biogas productivity lies in the range of 200–400%.

Comparison Of Different Mechanical Refining Technologies On The Enzymatic Digestibility Of Low Severity Acid Pretreated Corn Stover

The effect of mechanical refining on the enzymatic digestibility of pretreated corn stover (PCS) was investigated. A pilot scale refining test using a Szego mill was performed and showed approximately 10% improvements in biomass digestibility and 40% increase in xylose yield. This suggests the possibility to scale up a mechanical refining technique to obtain similar enzymatic digestibility glucose yield enhancement as achieved by PFI milling and extrusion technologies.

Use Of The Szego Mill In Grinding & Processing Biomass

Biomass utilization always requires at least some preliminary processing of the feedstock. Primary size reduction to a proper level for ease of handling is essential, followed usually by further downstream processing prior to final utilization. Important considerations for such processing are cost, equipment capacity and power consumption. The Szego Mill is a excellent candidate for such downstream processing, for example after wood has been chipped.

The purpose of this report is to summarize and present substantially all work done on biomass grinding/processing using the proprietary Szego Mill. This extensive compilation of Szego Mill-related information and experimental data will be of value to users of the mill in a wide range of potential applications.

Rapid Extraction of Canola Oil Using the Szego Mill

The simultaneous size reduction and solvent extraction of canola seeds were studied using a laboratory blender and a small, pilot-scale Szego mill. The laboratory tests established that over 95% of the oil may be removed from the seed in a single contact stage. The effects of contact time and solvent-to-seed ratio were investigated. In all cases the extraction reached some 90% of the equilibrium value after 3 min.

These tests demonstrated that the solvent milling of rapeseed in the Szego Mill can be highly effective in extracting oil from the seed, eliminating the need for the pretreatment steps of cracking, prepress and flaking.
