Scraped surface heat exchanger GS Nexus series

gas/gasstainless steelfor the food industry

Nexus is designed to meet market demand for high-quality products combined with low-cost production. With Nexus you can produce the entire range of crystallizing Fats & Oils products, i.e., consumer margarine, industrial margarine, shortening, low-fat spreads, recombined butter and butter blends. Nexus consists of up to 4 chilling tubes, all equipped with individual cooling systems, and can be operated with CO2 or ammonia as the refrigerant. It was one of the first scraped surface heat exchangers to use the environmentally friendly CO2 as refrigerant. The advantage of CO2 over traditional ammonia (NH3) is the higher efficiency which results in more cost-efficient production. Should you choose ammonia initially, you can change the refrigerant to CO2 operation at a later stage. The design is robust, reliable, and built to last to meet our customers’ ever changing production requirements. Nexus complies with all major pressure vessel directives. Function and Principles of Operation Crystallization takes place in the scraped surface heat exchanger (SSHE) which is the heart of a Fats & Oils (F&O) crystallization line. The product is pumped into the chilling tubes where it is cooled and crystallized. Scrapers in the rotor system are then pressed against the chilling tube by constant centrifugal forces during rotation ensuring that the crystallized product is very efficiently scraped from the interior tube surface. Benefits Multi-purpose machine for all edible Fats & Oils (F&O) products. Hygienic design suitable for the food industry. All product contacting parts are made in stainless steel AISI 316 or better.
