FT94X HTST/UHT Mini Pilot System Didactic Equipment Vocational Education Equipment Food Machine Trainer
DESCRIPTION The FT94X service unit contains the services, controls and instrumentation required to operate the tubular and plate heat exchangers described below. The FT94X may be specified with either or both of the heat exchangers. Switching between the two heat exchangers takes a matter of seconds. The service unit comprises: an eight inch touch screen control panel with the required controls and displays; a variable speed progressive cavity product feed pump with inlet level sensor and alarm to warn of low product level; a steam-heated hot water system for product preheating; automatic steam control valves for product preheating and final heating; a centrifugal CIP pump and other facilities required for CIP and SIP. Sensors show product inlet, preheat, final heating and outlet temperatures. Product preheat and final heating temperatures are set by the operator. Inlet and outlet product pressure is also shown. There are various service sensors: pressure, level and temperature – see process flow diagram for details. A sophisticated data logging package enables the measured data to be recorded onto a standard Windows PC (not supplied). The software records all temperatures, product and steam pressures, feed pump speed and many other sensor values. Data from optional accessories (e.g. the flowmeter) is also recorded. Data may be displayed in tables and graphs (both real time and comparisons across previous runs), and may also be exported to MS Excel. Interface: USB Software requirements: Win 98, ME, 2000, XP, Win 7/8/10 In addition FT94-59 Ethernet PLC update module is available. This accessory gives a direct link from a PC to update the software on the PLC using Dataworx™ Software (not provided).
