Dryers Machine

Vacuum Band Dryer are especially efficient for the continuous drying of temperature sensitive products. The vacuum inside this type of dryer lowers the aggregate level for evaporation so that efficient drying can be accomplished at lower temperature. This ensures that sensitive foodstuffs can be dried very gently and efficiently. It comprises a vacuum chamber housing a number of conveyor bands which pass over platens heated by steam. These units are supplied with a range of capacities.

Application:

• Malted Milk drying
• Fruit juice concentrate drying
• Herbal extracts drying
• Lumpy products & granulates drying

FBE designs and supply malted milk plant. Malted milk food is the product obtained by mixing Milk with malt extract and cereal grain. The paste formed is evaporated and vacuum dried to manufacture malted milk powder. The scrapped type evaporator with specially designed agitator shall be used to concentrate the product upto 70-80% TS then it is dried in Vacuum Band dryer.

The Rotary Dryer of material takes place inside the rotating cylinder. The rotating shell is acting as the conveying device and stirrer. The wet material is dried by contact with heated air. The dried material is exposed to the hot air to achieve low moisture content.

Rotary dryer is used to dry herbal extracts.

We are a noteworthy organization in the domain, engaged in providing a high quality range of Vacuum Shelf Dryer.

Vacuum drying is generally used for the drying of substances which are hygroscopic and heat sensitive, and is based on the principle of creating a vacuum to decrease the chamber pressure below the vapor pressure of the water, causing it to boil. ... The result is a significantly increased drying rate of the product.

In Horizontal Roller Dryer the product is distributed on rotating, steam-heated drums. The water in the product evaporates and is drawn off by a flow of air when it comes in contact with the hot drum surface.

The pretreated product is admitted to a trough formed by the cast iron drums and their end walls. A thin layer of product on the drums is heated quickly when it comes in contact with the hot surface. The water is evaporated and the layer of product on the drum dries. This film is continuously scraped off by knives in contact with the periphery of each drum.

The dried product falls into a screw conveyor in which it is ground into flakes. The flakes are then transferred to a grinder, and hard and burned particles are separated on a screen at the same time.

We have a fabulous range of Rotary Vacuum Dryer. These dryers are used in all chemical, biochemical, food and agrochemical industries.

• High drying rate
• Uniform drying avoids over heating of products

The FBE Vacuum Band Dryer consists of a vacuum chamber in which conveyer bands of food grade quality are arranged. The band passes over the hot plates heated internally by steam or hot water. Feed product is spread on the moving band and is dried as it moves on the hot plates.

Fluidized Bed Dryers (Batch or Continuous Type) used for drying for various types of Liquid concentrates efficiently. It can also reduce the energy requirement of a spray dryer plant when used as a second stage dryer for production of instant quality powders. Fluid bed dryer comprises of a top fluidizing chamber & a bottom air distribution chamber separated by a specially designed perforated plate. The feed of wet materials is dried by intimate contact with hot air when the material is in a fluidized state. A vibrating mechanism can be attached to give a forward motion cum agitation to the product at a controlled rate. It is also used as second stage dryer for many products.

SS Spray Dryer is transformation of feed from a fluid state into dried particulate form by spraying the feed into a hot drying medium. It is a continuous particle-processing drying operation. The feed can be a solution, suspension, dispersion, emulsion or slip. The dried product can be in the form of powders, granules, or agglomerates.

Feed is finely atomized and is introduced in the drying chamber along with hot air. The mixture of atomized feed and hot air moves towards the air exhaust of drying chamber. The time taken by this mixture to travel upto air exhaust is called as residence time of drying. During this residence time, the feed droplets loose its moisture to the hot air and are converted into dry powder particles. The dry powder falling on to the conical portion of drying chamber slides down to bottom of drying chamber with the assistance of vibrators/knockers and is collected in collection bag/bottle through the rotary valve located at the bottom of drying chamber.

The air leaving the drying chamber entrains some of the dry powder which is recovered in the cyclone separator and collected through rotary airlock. The air leaving the cyclone separator still has traces of dry powder, which is further recovered by scrubbing in wet scrubber or passing it through bag filter. Air from cyclone or bag house is sucked by induced draft fan

Fluid Bed Dryer
To avoid channeling effects and to ensure true fluidization, vibration is required, so FBE is used Vibrating fluid bed dryers in the powder manufacturing unit. After introducing a fluid bed into the spray drying processing, FBE has recognized that there was a distinct difference in the structure of fluid bed treated powder compared with powder from a pneumatic conveying system. The fluid bed treated powder was distinctly coarser and free flowing. The reason for better flow ability was a partial agglomeration.

FBE manufactures Fluidized Bed dryer in 2,3 or 4 sections. In double section FBD 1st section is for heating and 2nd is for cooling. In Triple section FBD 1st sections are for heating and 2nd and 3rd are for cooling. In four sections FBD 1st and 2nd section for heating and 3rd and 4th are for cooling.

Agitated Nutch Filter Cum Dryer

• High filtration rate.
• No contamination in final products.
• Controlling microbial contamination in final products.

Ring Dryers are especially suitable for drying of adhesive products that dry in falling rate periods and tend to agglomerate. The product is pumped to a special extruder discharging directly into the path of high speed rotating disintegrator beaters. The disintegrator is continuously swept with hot air borne recycled material flowing through the dryer for a second pass. Most water is removed in and immediately above the disintegrator. The final drying takes place in ring-shaped duct. This reduce the natural stickiness of the product and prevents material build-up within the dryer

Three Stage Industrial Dryer involves a transfer of the second drying stage into the base of the spray drying chamber and having the final drying and cooling conducted in the third stage located outside the drying chamber. It consists of a main drying chamber, static integrated bed chamber and vibro fluidized bed chamber.

In the main chamber, primary drying of the droplets takes place in the main chamber as they fall from the atomizer to the base of the chamber.

AThe second drying stage takes place as drying air is sucked through the powder layer. The moisture content of the powder falling on the Integrated bed is 12 – 20 % depending upon the type of product. This second drying stage reduces the moisture content to 8-10 %. The moisture content is very important to achieving the exact degree of agglomeration of the product and porosity of the powder layer.
The third and last drying stage for skim milk and whole milk concentrates takes place in the vibro fluidized bed dryer where the moisture contents of the powder reduce to 2.8% to 3.5%. Fluidized bedchamber is supplied with heating and cooling section. Only a small amount of powder leaves the plant together with the drying and cooling air as fines. This powder is separated from the air in a cyclone. The powder is recirculated, either to the main chamber or to a point in the process appropriate to the type of product and the agglomeration required.

Flash Dryers are used to dry efficiently those materials that can be transported pneumatically in large volume. During this conveying operation, small solid particles can be dried by pre heating the carrier air or gas to such an extent that it act as a drying medium. These types of dryers always operate in a co-current manner, and the drying takes place in a very short period of time. Flash dryers are probably the most suitable forms of atmospheric pressure continuous direct dryers. These dryers are most suitable for drying wet materials with a moisture content is in the form of recoverable solvents.
