Industry-leading expertise | Superior results for our customers

Today, drying processes are widely used in food product processing. In many cases vacuum belt dryers are the method of choice due to their efficiency in handling large volumes and having a gentle drying process. Typical applications and pro­ducts include: Plant extracts Hydrolyzed vegetable proteins (HVP) Malt drinks Bakery products (yeast) Meat products (broth) Specialized nutritional products Fruit juice concentrate Pharmaceutical extracts

Sefar offers a wide range of synthetic fabrics in open and closed mesh for conveying and drying products. Our vacuum dryer belts are made of polyester (PET) polymer – selected according to your demands. Belts having different pore sizes for different solid contents (viscosity) of products Customized solutions that meet the industry’s most demanding requirements (e.g. high temperatures, chemical resistance and long lifetime) Integrated production: all crucial steps from yarn production, weaving, finishing and fabrication of ready-touse belts More than 180 years experience in the food industry. With over 35 years supplying belts for vacuum belt dryers All belt fabrics and closures are recommended for applications in the food industry and are compliant with food safety regulations.

Drawing from market-leading expertise in all aspects of precision fabrics, Sefar has developed a unique and innovative product range for today’s needs in vacuum belt drying. Covering the most commonly-used bandwidths of drying temperature and solid content levels, SEFAR TETEX® DRY fabrics are ideal for a multitude of applications. They provide an efficient and attractive alternative to PTFE coated / non-permeable materials. The individual pore sizes of the fabrics provide the ability to match the right product viscosity with the desired steam permeability. The average long service life combined with its low down-time properties make them ideal for today’s industry requirements.

SEFAR TETEX® DRY | Product benefits

Permeability properties

Unique permeability settings allow steam to penetrate the fabric and eliminate bubble formation while sustaining performance with solid content > 30%.

Mechanical stability

Precision controlled fabric finishing provides low shrinkage/elongation and efficient belt alignment as well as long service life (up to 14 months). Suitable for application temperature of up to 165° C.

Reduced downtime

Fast and easy installation supported by efficient closing system. Belt is ideal for CIP cleaning.

Clogging resistance

Smooth surface makes product release easy and reduces particle entrapment in the pores of the fabric.

Food safety compliancy

All components comply with food safety regulations – during full service life.

Because SEFAR TETEX® DRY is a high precision open-mesh fabric, the water evaporating after washing and restarting the dryer does not condensate under the belt. Steam can permeate through the fabric resulting in earlier operational readiness and less strain on the fabric.

SEFAR TETEX® DRY | Making-up of belts

Making-up of belts Sefar’s market-leading expertise not only includes providing the most suitable fabric for customers’ applications, it also means offering the best possible styles of making-up. Fitting the belts to the specific machine requirements is vital for smooth and efficient performance.

Sefar belts can be fitted with an alligator closure: this results in a fast, easy and reliable connection of belt ends. Each closure strip is made from one piece, reducing the risk of individual teeth breaking off and getting into the product stream.

SEFAR TETEX® DRY belts are also available without a closure. This allows maximum flexibility for example when ultrasonic spot-welding is preferred.
