Armfield FT 40

General Overview
Nodpfx Ajydh Agjf Njwb
Pasteurizing, cooling, hardening, emulsifying, reconstituting, incubating, and mixing are all processes relevant in the food processing laboratory. The Armfield Multi-purpose Processing Vessel is capable of performing all these functions as a standalone, mobile unit. Its mobility allows it to be positioned in the laboratory next to other equipment for which it can be used, and also allows for easy storage. The hygienically designed, jacketed vessel has a working volume of 10 to 15 liters, enabling experiments and demonstrations without the need for large quantities of raw materials. An electric heating element at the bottom of the jacket heats water in the jacket, which in turn heats the contents of the vessel. This method provides gentle heat transfer to ingredients, which are often sensitive to heat, and local 'hot spots' are avoided through the convective distribution of heat. Cooling is achieved simply by feeding water from the mains water supply through the jacket. For active cooling, chilled water is circulated in a closed loop by an ice-bank chiller integrated in the equipment's base. A variable-speed emulsifier with different emulsifying head options can be lowered into the process liquid. Practical experience can be gained by students, and the comprehensive instrumentation allows for complete process documentation. An automatic valve changeover system enables straightforward operation, allowing the student/trainee to easily select the required process instead of operating a series of manual valves.

9.1 Overview
The double-walled stainless steel vessel (1) has a polished, hygienic surface and a working capacity between 10 and 15 liters. The contents are indirectly heated by a heating cartridge (16) in the bottom of the jacket. The heater is protected against overheating by an adjacent thermostat (17). An emulsifier (2) can be mounted in the vessel using the locking handle (5). The ON/OFF and speed controls (14) of this device are located on the motor housing and not on the operating console. A green running light (7) indicates when the emulsifier motor is on. The emulsifier head (3) can be easily exchanged for any of the supplied alternatives by simply removing the finger nuts securing the head to the drive shaft. A lid (6) prevents airborne contamination during prolonged thermal treatment. Chilled water is circulated from an ice bank (12) below the processing vessel. After a period required to build up the ice bank, this chilled water is supplied to the vessel jacket, cooling the contents to a temperature suitable for storage/hardening. The ice bank is typically used after an initial quick cooling by circulating cold water from a mains supply. 3-way valves (10) and (11) are used for automatic selection between open-loop cooling and closed-loop chilled water. In both cases, the water passes through a flow meter (13), where the flow rate can be manually adjusted using a control valve (14). From the flow meter, the water enters the base of the vessel jacket after passing through an inline check valve (15)…
