This is a basic unit for studying of tray drying by hot air. 

The unit consists of a rectangular duct.  Air is drawn into the duct by an axial flow fan with guide vane, wire mesh screen and flow strengthener at the front end of the duct.  Fan speed is adjustable.  A bank of electric heaters behind the fan raises air temperature. Behind the heater is a drying compartment with transparent access door. A rack of trays is suspended from a balance above the duct.  Temperatures and humidity before and after the drying trays are measured.

Filter press is used for clarifying intermediate products. Such as suspension water. A suspension water is prepared in a feed tank. A stirrer ensures that the solid remains suspended and does not settle. The pump delivers the suspension water into the individual separating chambers of the filter press. The filtrate passes through the filter cloth and flows into the filtrate tank.

The flow rate through the filter press is controlled by a pump. The pressure occurring during filtration is indicated on a pressure gauge.

The unit is painted steel frame with adjustable footings.

This equipment is for demonstration of gas absorption principles.

The unit consists of two packed absorption columns, one on top of another. The two columns are held together by steel frame and are packed by Raschig glass rings. A centrifugal pump draws a liquid from a feed tank underneath the column and delivers to the top of the column where it falls down through the packing and to the storage tank. Flow rate is indicated on a variable area flow meter.

A gas to be absorbed such as carbon dioxide is drawn from a pressure cylinder through a flow meter and is mixed with an air stream supplied through an air blower. Air flow rate is measured by a flow meter. The mixed gas enters the column at the bottom of the column and rises up to the top.

Pressure tapping points and gas sampling points are provided at the bottom, middle and top of the column to measure pressure drops by manometer and differential pressure gauge. Carbon dioxide content is determined by a Hempel apparatus (optional). All instruments are mounted on a panel.

This equipment demonstrates a process for separation of a mixture (one soluble in another) of two liquids of different boiling points.

The unit consists of reboiler, two distillation columns, condenser, reflux tank, top product tank, feed tanks with feed pump, feed preheater, bottom product tanks, measuring instruments, and other accessories.

An initial feed is added to the reboiler where the vapor with higher concentration of the lower boiling point component rises in the distillation column. The vapor leaves the top and is condensed in the condenser and collected in the reflux tank. Part of the condensate in the reflex tank is fed back to the top of the column where heat exchange is taken place with the rising vapor. This results in the vapor phase being richer in the lower boiling point component, and the liquid phase being richer in the higher boiling point component. The liquid phase moves down to the reboiler.

The feed is pumped from feed tanks, preheated in a preheater, before delivery to the distillation column. The feed is partially evaporated in the column on its way to the bottom where it is heated to boiling.

The hot mixture in the reboiler is rich in higher boiling point components is used to preheat the feed and collected in the bottom product tanks.

Two columns, sieve plate column and packed column with Rasching rings, can be interchanged simply by valve control. Lagging is provided for reboiler, sieve column, condenser, and preheater.

The unit is installed on a stainless steel frame.

The deep bed filter is a demonstration unit for treatment of water with suspended particles by sand filtration.

The unit consists of a filtration column is fitted with vertical row of pressure tapping points on one side and similar sampling points on the other side. Both ends of the column are closed with flanges for liquid inlet and outlet. A pump delivers raw water from the raw water tank to the top of the column. Suspended particles are trapped in the sand filter as water flow down through the column to the bottom via filter. The treated water is collected from the bottom in a treated water tank. Hoses connect pressure from the tappings along the side of the column to a manometer bank. Samples of raw water is collected from the sampling points on the side of the column. A manometer bank is provided for measurement of pressure along the column.

Overtime more particles are deposited in the filter which increases the pressure drop across the filter and flow rate decreases. Backwashing is required using treated or clean water and pressure drop is reduced again. Required pipings are provided.

The filter unit is on a steel frame.
