The plant includes a cabinet where switches and other electric control elements and rotections necessary to ensure the safety of people and equipment in accordance with current electrical regulations are installed. All the elements of the Plant For The Study Of Erosion Corrosion are mounted on a structure of about 1 m. (W) x 3 m. (L) x 1 m. (H), made of 40x40square tube in stainless steel, provided with selflocking wheels for easy movement and location.
Operation of the Plant For The Study Of Erosion Corrosion
Plant For The Study Of Erosion Corrosion tank is complete with stirring to keep the mixture in suspension, a heater for heating the fluid, a sensor, and a digital controller for controlling the parameters in the tank.
Water with suspended material is stored in a tank of 1000 L capacity made of stainless steel with drain valve and manhole for filling.
The suspension is driven by a second centrifugal pump of stainless steel with similar characteristics to the previous one through a pipe of about 65 mm. diameter, U shaped, built in plastic material or stainless steel and is returned back to tank, thus creating a closed circuit.
The recirculation flow of the liquid to the tank is controlled through a valve that regulates the flow of water driven to the pipe. The flow driven by the pump can be displayed on a rotameter.
The Plant For The Study Of Erosion Corrosion tank is thermally insulated to prevent heat loss. In order to fill the tank there is a centrifugal pump in stainless steel that gives a maximum flow of 45 m3 /h with a power of 1.5 kW.
The column is supplied filled with glass Rasching rings 9x9 mm, and also supplied with polypropylene Pall rings, for the replacement of the glass Rasching rings in order to be able to study the effect of the filler on the efficiency of the absorption and desorption process. The main element of the Absorption Desorption trainer is a column of 1400 mm. height and 80 mm in diameter made in glass. The plant has pressure taps at the bottom and at the top of the column and two intermediate taps, through quick couplings connected to a water column differential manometer that allows determining the pressure drop within the column and the effects of the speeds of the liquid and of the gas on the pressure drop within the column. In both cases, the column filling maximizes the gas liquid contact surface, so that it produces the maximum possible absorption or desorption.
The Absorption Desorption plant also has three intermediate samplers for sampling both the liquid phase and the gas phase and 4 temperature probes with digital display. In a flow meter positioned on the liquid inlet line can be displayed the liquid inflow. This flow meter is made of borosilicate glass and stainless steel with stainless steel float. The liquid is introduced through the top of the column through liquid diffuser, which permits the dispersion of the liquid and thus a better distribution of the fluid within the column. The liquid phase is stored in a tank of about 30 liters of capacity made of polyethylene. Water or absorption liquid is led into the reaction column through a metering pump, which allows setting the incoming water flow to the column.

The centrifugal force separates the heavier phase (material) and forces it towards the periphery. The feed material is poured into the rotating basket (bowl). The first material discharged will be the purified light phase. After this the heavier phase (if liquid) can be drained in the same fashion by continuing the rotation of the tube. After a couple of minutes a pitot type discharge tube is manually rotated into the spinning liquid which thereby is drained from the bowl. Alternatively, with more viscous materials and solids, the machine is stopped and the bowl quickly removed for cleaning.

The vat is constructed from high quality stainless steel, the interior having a mirror finish.
All vessels, pipes, valves and fittings in contact with process materials are constructed in stainless steel with the exception of the borosilicate glass solvent condenser. The support framework is also stainless steel. The vessel base is equipped with an indirect steam chest for process heating. Direct steam is injected at a variable rate through a distribution pipe positioned above the mesh. A similar distribution pipe positioned near the top of the vessel allows solvent to be sprayed uniformly onto the bed of material.
The cylindrical extractor/desolventiser with a hinged lid for charging the extraction material, has a base inclined slightly towards a port for discharging the extracted and desolventised meal. The miscella tank, positioned directly below the extractor to collect the draining liquid, is also a cylindrical vessel incorporating a steam chest as its base. Material is supported above the base by a perforated plate covered with a fine woven mesh so solvent may drain through to the miscella tank whilst retaining the solids.
Vapour from the vessels, produced in the desolventising process,is directed by ducting to the solvent condenser, an inclined cylindrical glass tube containing a double coil through which cooling water is circulated. This vessel also incorporates a direct steam distribution pipe through which steam can be metered at a variable rate. Condensate (usually a mixture of solvent and water) drains into the solvent water separator tank which allows thorough separation of the solvent and water by a gravity process.
The press is driven at the discharge end through a single reduction helical gearbox. Seed or ground meal is gravity fed to the press from an integral feed hopper fitted with a manually operated shut-off slide.
The power source is a 4kW, 4 pole, 3 phase electric motor.
The thickness of the press cake may be varied.

The blast freezer and fluid bed sections are contained, along with the fan and evaporator, inside an insulated cabinet. Inside the cabinet, a fan with adjustable impeller transports air from the interior of the cabinet into the freezer ducting and through the evaporator tube bank where it transfers heat to the refrigerant. Access doors to both sections are fitted with observation windows and an electrically heated surround to prevent the doors from freezing in the closed position.
The blast freezer section contains 5 trays on to which the food samples to be frozen are placed. The air, now reduced in temperature, passes trought he tray section which can be observed through a removeable perspex panel. It then changes direction and passes vertically up through the fluid bed section, back into the cabinet space where it is again circulated by the fan.
There is a facility for a suitable anemometer to be inserted into the ducting to allow the air speed to be measured. There is a facility for thermocouple sensor leads to pass into the ducting and through the cabinet wall so that freezing temperatures and rates can be monitored externally.
The system is supported within a stainless steel framework and requires only connection to suitable steam, electrical and water services for operation.
The component parts of the industrial process have been scaled down, feed tank, vapour / liquid separator, condenser, concentrate tank, condensate tank, CIP pump and vacuum pump, all manufactured from hygienic materials such as stainless steel, PTFE and glass. The single tube-in-jacket evaporator replicates industrial units which often contain scores of much longer tubes within the steam space.
Only 0.65m² of floor space is required to install the evaporator and it has been designed to fit easily into a room of standard height.
Pasteurising temperatures and holding times are easily adjusted, allowing the effectiveness of the product treatment to be investigated. When correctly operated, cleaned and sterilised can produce a correctly treated and pasteurised product. However it is not intended that this apparatus be used to manufacture products for human consumption. Although primarily designed for use with milk, other food liquids can be pasteurised providing that their solids content is not too high.
The Laboratory Pasteuriser accurately reproduces in miniature the industrial High Temperature Short Time process. Nominal throughput is only 10 litres/ hour.
The three stage plate heat exchanger of the achieves these parameters by
Transfers heat from the treated product to the feed liquid. Full instrumentation and controls are provided to regulate heating water temperature and also feed pump speed which in turn regulates holding time. This provides dual benefits in reducing the energy required to reach the pasteurising temperature and in reducing the cooling required. An optional Chilled Water Circulator is available.
Heating the process liquid with hot water prior to its entry into the holding tube and then by
Cooling with cold water to storage temperature. An intermediate heat exchanger.
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%.

The is available in two basic configurations. The standard is the simplest system. As standard the filtration assembly works with polymer membrane filters (90mm diameter) and sample filters are included for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). A backpressure valve is used to adjust the transmembrane pressure with a maximum allowable system pressure of 40 bar (analogue pressure indicator). A wider range of filters are available on request. It uses a high pressure stainless steel piston pump to circulate product from a food vessel to the filtration assembly with simple on/off control.
The 50 is an enhanced unit, with all the additional benefits of computer control, data logging and diafiltration capability. There is also an electronic mass balance to measure the mass of permeate collected. This option also enables diafiltration using a peristaltic pump and high level sensor. It includes an electronic pressure sensor to measure filtration pressure (0-40 bar) and electronic temperature sensor (thermocouple) to measure retentate temperature. It also includes a feed pump speed controller, which enables the retentate cross flow velocity over the filtration membrane to be varied. The data from all these is logged in the software enabling plotting of permeate flow rate with time so that the effect of variables (filtration pressure, cross flow velocity, product temperature and diafiltration) on process performance can be determined. The software can be used to define the mass of permeate collected prior to addition of water/buffer (batch diafiltration). Communication to the PC (not supplied) is via an internal USB interface.
Features:
Suitable for microfiltration, ultrafiltration, nanofiltration and reverse osmosis membranes and pressures. Pressure operating range of 1-40 bar.
Uses a standard filtration size of 90mm enabling a wide range of filtration membranes to be used
Optional ceramic membrane available
Supplied with a range of polymer membranes.
The feed reservoir, positioned over the centrifuge, is made from grey anodised aluminium and contains a polypropylene on/off valve.
A supporting framework intended for bench mounting houses the separator, complete with its variable speed drive control unit, food reservoir and the necessary ancilliary equipment.
A motor, directly coupled to the separator bowl, is mounted vertically in a cast aluminium casing with cushioned clamping feet. The casing acts as the support for the separator.
The separator bowl assembly is made up of stainless steel disks and an anodised aluminium casing with nitrile rubber seating ring, housed in a polypropylene shroud which incorporates the cream and skimmed milk outlets.
This is fully self-contained in a mobile cabinet. Connection to cooling water and a suitable electrical supply is all that is required for normal operation. Comprehensive instrumentation is provided with digital meters displaying temperatures and system pressure. In addition to the membrane module, the cabinet also houses feed and permeate tanks, a plate heat exchanger and positive displacement pumps.
It uses a membrane module which accommodates all PCI membrane types. The unit is supplied with a pack of both R.O. membranes and U.F. membranes.
The RO/UF unit has an efficient clean-in-place facility and is easily dismantled for servicing or maintenance.
All parts in contact with the process fluid are constructed from hygienic design materials such as stainless steel, PTFE and silicone rubber.
The filtration membranes differ only in length and quantity from those installed in the full-scale plant. Using small quantities of process fluid, operating parameters can be established and then optimised to effect a confident transition to full-scale.
Membranes can be installed or removed rapidly for use in either process.
