Corn Wet Milling

Many filtration steps are required in the wet milling of corn. Synder’s membranes, ranging from Micro to Nanofiltration, are capable of handling any of your application needs. From the removal of microorganisms to the concentration and clarification of corn syrup, Synder’s comprehensive line of membranes is ready to exceed your expectations. 

Gelatin Concentration

Concentration of suspended colloids is critical in the production of gelatin. Synder’s Ultra & Microfiltration membranes provide optimal retention rates for concentrating gelatin while removing unwanted microorganisms.

Juice Processing

Ultra & Nanofiltration are widely used in the production of high quality juices. Synder Filtration’s line of Ultra and Nanofiltration membranes can remove starch, pectin, proteins, and polyphenolic compounds. Microfiltration can also be utilized for the removal of microorganisms.

Natural Polymers & Xanthan Gum

Synder’s Micro and Ultrafiltration membranes are ideal for concentration of natural polymers. MF and UF filtration are required in the production of Xanthan gum. Synder’s MF and UF membranes provide an optimal combination of retention rates and throughput required for commercial production while removing harmful microorganisms. 

Dealcoholization

Traditional methods of manufacturing non-alcoholic beer require the worth to be processed in a way that doesn’t leave much room for imparting flavor. Instead of making a non-alcoholic beer why not remove the alcohol from regular beer, thus providing a non-alcoholic beer with much of the flavor of a regular draft. Synder’s NFX Nanofiltration membrane is capable of concentrating and removing alcohol efficiently with minimal effect to the flavor profile. 

Maple Syrup

Maple syrup production from maple sap is a time and energy consuming process that requires the sap to be reduced down to thick syrup. Conventional boiling reduction methods are tedious and use significant energy. Concentrating the sap using the NFX Nanofiltration membrane by Synder can reduce overall processing time and operating costs. 

Fragrance Recovery

Synder Filtrations NFX Nanofiltration membranes can be used to concentrate aroma compounds to manufacture natural & artificial fragrances. NFX captures and concentrates alcohols, aldehydes, amines, esters, ethers, ketones & terpenes.

Synder offers a wide range of Microfiltration, Ultrafiltration and Nanofiltration membranes suitable for various food & beverage applications.
For the past thirty years, membrane filtration technology has been used throughout many stages of corn wet milling. As opposed to conventional methods such as centrifugation, membranes are able to save manufacturers in operational and discharge costs. Membrane filtration can also be used to clarify mud, the by-product of the conversion of starch to corn syrup, to produce a clear permeate stream ready for concentration. Common membranes used for this application include ST, BN, LY, LX, and FR.

Synder Filtration supplies elements with a wide spectrum of pore sizes to accommodate the process goals within the gelatin industry. Typically, microfiltration membranes are initially applied to remove fat and large suspended solids from the gelatin extract feed stream. Diafiltration is often applied as well to increase the total yield. Once the extract has undergone microfiltration, ultrafiltration is used to concentrate the gelatin, as an energy saving alternative to using a direct evaporator. Recommended membranes include FR, ST, MT MAX, NFW.

For juice processing, membrane filtration has become an attractive alternative, since the technology requires less energy and has minimum impact on the environment.  It was found that after colloids, gums, proteins, starches, and color impurities were removed by microfiltration or ultrafiltration processes, the permeate could be sent directly to nanofiltration spiral-wound elements to concentrate sugar and desalinate the permeate if needed. Common membranes include NFX and NFW.

Lastly, Xanthan gum is an important microbial polysaccharide widely used throughout the food, agricultural, and oil industries as a thickening, stabilizing, and suspending agent. By concentrating thexanthan fermentation broth from 2.5% to 15% (w/v), up to 80% of the energy can be saved in recovering xanthan gum by using ultrafiltration to concentrate the broth prior to alcohol precipitation Due to the shear-thinning property of xanthan polymer, ultrafiltration at high pumping rates is required, and Synder’s MAX elements such as LX (MAX), can also be implemented for conditions requiring high temperature and extreme pH.

In the production of maple syrup, maple sap is concentrated from roughly 2% sugar to 66%+ sugar. This concentration is achieved primarily by evaporation, which is a very costly and energy intensive process. If the sap can be processed and concentrated with membrane technology to reduce the evaporation required to achieve a 66%+ sugar concentration, a significant cost savings could be seen by maple syrup producers. Synder’s NFX Nanofiltration membrane was tested against the leading competitor’s NF membrane to gauge performance in concentrating the sap from 2-8% sugar.
