Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging products. To be considered "dried", the final product must be solid, in the form of a continuous sheet (e.g., paper), long pieces (e.g., wood), particles (e.g., cereal grains or corn flakes) or powder (e.g., sand, salt, washing powder, milk powder). A source of heat and an agent to remove the vapor produced by the process are often involved. In bioproducts like food, grains, and pharmaceuticals like vaccines, the solvent to be removed is almost invariably water.

In some products having a relatively high initial moisture content, an initial linear reduction of the average product moisture content as a function of time may be observed for a limited time, often known as a "constant drying rate period". Usually, in this period, it is surface moisture outside individual particles that is being removed. The drying rate during this period is mostly dependent on the rate of heat transfer to the material being dried. Therefore, the maximum achievable drying rate is considered to be heat-transfer limited. If drying is continued, the slope of the curve, the drying rate, becomes less steep (falling rate period) and eventually tends to nearly horizontal at very long times. The product moisture content is then constant at the "equilibrium moisture content", where it is, in practice, in equilibrium with the dehydrating medium. In the falling-rate period, water migration from the product interior to the surface is mostly by molecular diffusion, i, e. the water flux is proportional to the moisture content gradient.

DRYING EQUIPMENT :

Tray Dryers :In tray dryers, the food is spread out, generally quite thinly, on trays in which the drying takes place. Heating may be by an air current sweeping across the trays, by conduction from heated trays or heated shelves on which the trays lie, or by radiation from heated surfaces. Most tray dryers are heated by air, which also removes the moist vapours.

Tunnel Dryers :These may be regarded as developments of the tray dryer, in which the trays on trolleys move through a tunnel where the heat is applied and the vapours removed. In most cases, air is used in tunnel drying and the material can move through the dryer either parallel or counter current to the air flow. Sometimes the dryers are compartmented, and cross-flow may also be used.

Roller or Drum Dryers :In these the food is spread over the surface of a heated drum. The drum rotates, with the food being applied to the drum at one part of the cycle. The food remains on the drum surface for the greater part of the rotation, during which time the drying takes place, and is then scraped off. Drum drying may be regarded as conduction drying.

Fluidized Bed Dryers :In a fluidized bed dryer, the food material is maintained suspended against gravity in an upward-flowing air stream. There may also be a horizontal air flow helping to convey the food through the dryer. Heat is transferred from the air to the food material, mostly by convection.

Spray Dryers :In a spray dryer, liquid or fine solid material in a slurry is sprayed in the form of a fine droplet dispersion into a current of heated air. Air and solids may move in parallel or counterflow. Drying occurs very rapidly, so that this process is very useful for materials that are damaged by exposure to heat for any appreciable length of time. The dryer body is large so that the particles can settle, as they dry, without touching the walls on which they might otherwise stick. Commercial dryers can be very large of the order of 10 m diameter and 20 m high.

Pneumatic Dryers :In a pneumatic dryer, the solid food particles are conveyed rapidly in an air stream, the velocity and turbulence of the stream maintaining the particles in suspension. Heated air accomplishes the drying and often some form of classifying device is included in the equipment. In the classifier, the dried material is separated, the dry material passes out as product and the moist remainder is recirculated for further drying.

Rotary Dryers :The foodstuff is contained in a horizontal inclined cylinder through which it travels, being heated either by air flow through the cylinder, or by conduction of heat from the cylinder walls. In some cases, the cylinder rotates and in others the cylinder is stationary and a paddle or screw rotates within the cylinder conveying the material through.

Trough Dryers :The materials to be dried are contained in a trough-shaped conveyor belt, made from mesh, and air is blown through the bed of material. The movement of the conveyor continually turns over the material, exposing fresh surfaces to the hot air.

Bin Dryers :In bin dryers, the foodstuff is contained in a bin with a perforated bottom through which warm air is blown vertically upwards, passing through the material and so drying it.

Belt Dryers :The food is spread as a thin layer on a horizontal mesh or solid belt and air passes through or over the material. In most cases the belt is moving, though in some designs the belt is stationary and the material is transported by scrapers.

Vacuum Dryers :Batch vacuum dryers are substantially the same as tray dryers, except that they operate under a vacuum, and heat transfer is largely by conduction or by radiation. The trays are enclosed in a large cabinet, which is evacuated. The water vapour produced is generally condensed, so that the vacuum pumps have only to deal with non-condensible gases. Another type consists of an evacuated chamber containing a roller dryer.

Freeze Dryers :The material is held on shelves or belts in a chamber that is under high vacuum. In most cases, the food is frozen before being loaded into the dryer. Heat is transferred to the food by conduction or radiation and the vapour is removed by vacuum pump and then condensed. In one process, given the name accelerated freeze drying, heat transfer is by conduction; sheets of expanded metal are inserted between the foodstuffs and heated plates to improve heat transfer to the uneven surfaces, and moisture removal. The pieces of food are shaped so as to present the largest possible flat surface to the expanded metal and the plates to obtain good heat transfer. A refrigerated condenser may be used to condense the water vapour.

The Authority for Standard

The HVAC industry has responded to this indoor air quality (IAQ) concerns through its professional organization The American Society of Heating and Refrigerating and Air Conditioning Engineers which is Popularly known as ASHRAE

ASHRAE have issued IAQ Standard 62, entitled "Ventilation for Acceptable Indoor Air Quality". This standard specifies and stress on the need for continuous outdoor air ventilation as well as the importance of maintaining indoor humidity levels.

How to Recover Heat?

The combination of heat and humidity recovery of rotary heat exchangers is a highly efficient energy-saving. This is not a formula but is a Technology.

In the most of installation, the wheel is mounted in air handling unit AHU. It is positioned Supply and exhaust air each pass through half of the wheel in counter flow directions. The rotor media is a rotating transfer media.

In air-conditioning area, the cold air from air-condition room will pass through the half section of rotating honey comb cooling the metallic media which is Aluminium or other metal foil. This continuous rotating cooled media, after coming in other half section of frame, will cool the hot air coming from outside in the air-conditioned area.

It temporarily takes up the heat from the warm air stream and releases it in the colder air stream.

DevFresh Heat Exchanger Wheel (HEW) exchanger recovers both sensible (temperature) and latent (moisture) energy, and does effective job on Recovering the Heat and Humidity.

We are providing three hundred litters capacity stainless steel fabricated motorised with gear box.

The functionality of a cross flow plate heat exchanger is to exchange or transfer thermal energy among the airstreams in air-conditioning unit. It is generally utilized in ventilation or cooling system, where heat need to transferred from one airstream to another.

It contains thin metal panel generally aluminum in which the energy is exchanged through panels. It doesnt allow humidity to enter in airstream, hence avoids the risk of short-circuiting.

Traditionally, A Cross flow plate heat exchanger is square & cross section in shape having thermal efficiency up to 50-60%. It is widely used in various applications due to its less cost. But sometimes it is required to have more thermal efficiency up to 75-80%, so dual cross-flow heat exchanger will be more useful. These kinds of Heat exchangers are widely used in may heat recovery systems like in large hospitals, food industries, green building, Clean rooms , Bar, Pubs, Mall, Commercial Places, Cold storage etc.

Applications:

• Heat recovery from exhaust air for space heating for factories, offices and warehouses.


• Pre-heating/cooling of incoming air for air-conditioning units using exhaust warm/cool air.


• De-humidification of air streams.


• Electrical equipment cooling.
