Nexus - Pilot Plant For Fat Crystallization - Small Scale Scraped Surface Heat Exchangers

Product Type:
Systems / Crystallization

The Gerstenberg Schröder Nexus Pilot Plant is a highly flexible, modular system designed to test various high-viscosity applications within the Dairy, Fats & Oils and Processed Foods industries. It gives you the opportunity to process small-scale samples under exactly the same conditions as those generated in large-scale production facilities.

The Nexus Pilot Plant is designed for high efficiency and low energy consumption using environmentally friendly and highly-efficient CO2 as refrigerant.

Features

Nexus pilot plant consists of several individual skid mounted modules. All modules are completely piped, wired, and tested.

The core module is a highly flexible module based on a table design with up to 4 positions for SSHE and pin rotor machines, using CO2 as refrigerant. Nexus SSHE pilot plant is provided with a built-in CO2 compressor unit. The system also includes a SCADA system with a built-in touch screen interface.

Add-on tables for separate pin rotor machines, inverters, and resting tubes are available.

Furthermore, modules like a skid mounted 2-tank batching system, a pilot high pressure pump, pasteurizer- and rework-skids, SSHE for cold water and steam (BGS) are available. The skidded emulsifying system Nexus Pilot ERS is available for processed food products.

The flexible connection pipes which combine the various units and modules are easy to mount and dismount. It facilitates fast set-up alterations according to processing or application changes.

Function and Principles of Operation
Crystallization takes place in the scraped surface heat exchanger (SSHE) which is the heart of the crystallization line.

The product is pumped into the chilling tubes where it is cooled and crystallized. The scrapers in the rotor system are pressed against the chilling tube by constant centrifugal forces during rotation. This ensures that the crystallized product is very efficiently scraped from the interior tube surface.

Capacity
40-160 kg/hour

Advantages

  • The flexible modular system makes Nexus pilot plant ideal for heating, cooling, crystallizing, and emulsifying of various kinds of dairy, fats & oils and processed food products.
  • The pilot plants are easy to scale-up and give you the opportunity to process small-scale samples under exactly the same conditions as those generated in large-scale production facilities.
  • Completely piped, wired, and factory tested including SCADA system and operator panel for plug-and-play start-up.
