The refrigeration circuitry includes a water cooled condenser complete with isolating valves, manual expansion valve, evaporator, variable area flowmeter for mass flow of refrigerant, filter/drier unit, sight glass and over pressure cut-out for unit protection. The unit is designed to use Tetrafluoroethane as the refrigerant with a twin cylinder reciprocating compressor, belt driven by the variable speed dynamometer.
The evaporator coil is mounted in an electrically stirred water/glycol mixture contained in a thermally insulated, stainless steel tank. The water/ glycol mixture is protected from over temperature conditions by a thermostat should the heater should be left on when the compressor is not circulating refrigerant. Heating of this water/glycol mix is infinitely variable enabling balanced experimental conditions over a wide range of temperatures to be obtained.

The electrical components for the start and operation of a refrigerant compressor are clearly visibly arranged in a transparent showcase and already wired. The capacitor and start-up relay required for the motor are examined. Identifying electrical faults in refrigeration systems requires comprehensive knowledge this knowledge includes the design and operation of the individual electrical components as well as the reading of circuit diagrams. It helps to acquire this knowledge. The simulation of 15 different faults, e.g. coil fracture in the motor, short circuit in the operating capacitor or welded contacts in the start-up relay, is possible. Typical protection devices, such as circuit breaker and automatic fuse, are also arranged clearly visible.

The Pressure Homogeniser has been designed to complement the other processing equipment in the miniature-scale R & D range. The unit can also be used for salad creams and sauces. The double action of the homogeniser valve causes the mixture under pressure to be subjected to shear and compressive forces between the valve faces and impinge violently against the walls of the chamber, ensuring thorough dispersion. This index refers to testing homogenised product for fat content at the top and bottom of a sample and comparing the difference. Normal standards require an index of less than 12%. It is particularly useful for disintegrating fat globules in milk, ice cream and UHT dairy products. Results of performance using whole milk gave homogenisation indexes of 5%.
Features:
Hardened stainless steel cylinder block, valve and piston
Positive displacement piston
Specially developed, double action Stellite homogenising valve, eliminates the need for multiple valve heads
Rapid throughput, 45 litres per hour
Integral electric motor drive
Homogeniser index less than 5%.

The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components and the flow measuring devices are arranged. Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Piping Loss Test Set, Large is a self contained water circulating unit for studying the friction losses in pipes, pipe fittings, and valves and to determine coefficients of discharge for primary flow measuring devices at various flow rates. Flow rate is obtained from a water meter and a stop watch. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses. The unit is on stainless steel frame on wheels. The pressure drop is measured by differential pressure using manometers. Pressure tapping is by small ball valves with quick connection.
