Vacuum Shelf dryers provide rapid drying of heat sensitive, air-sensitive & pyrophoric materials, or materials that require drying without agitation. Heat sensitive materials can be dried at low temperatures under vacuum, since the environmental pressure is reduced below the vapour-pressure of the contained water or solvents. Oxidation or Contamination by Air is eliminated. Recovery of expensive solvents can be virtually complete. Hollow Fibers, Medical Devices, Chemical Salts, Fine Chemicals, Dyes, Glandular Products, Pharmaceuticals and Food Extracts (Gluten, Glues, Pepsin), Rubber Explosive, etc. are ideally suited for drying in this manner. Environment Principally, Drying under vacuum is environmentally friendly because the Evaporated Solvents can easily be re-condensed. These solvents can then either be recycled or disposed of without any problem. Drying of solvents in Ex-proof ovens may solve the safety problem in the oven but not the environmental aspect. The solvent vapour is blown out of the oven through the exhaust system Furthermore, there is a risk of uncontrolled mixture formation. Features : A major design feature incorporated in this series of vacuum dryers is the placement of all shelf and manifold connection outside of the chamber, avoiding the possibility that leaks might develop within a chamber and contaminate the product being dried. This feature also simplifies the maintenance of these connection by making access to them more convenient. Charge temperature measuring facility provides exact picture of the process. It measures the temperature directly at charge (material). A PT-100 Temp. Sensor enters the vacuum chamber via connection at the top Rear. "SANDWICH" Type High Thermal efficiency Stainless Steel Shelves with the heat transfer fluid circulation. Even heat distribution through whole shelf surface by baffles within shelves. Chamber walls are heated externally to prevent condensation on the internal walls. Rounded edges in walls shelves and product trays in order to facilitate cleaning and prevent accumulation of dry product residue and practical formation

Steam Tube Dryers The Sakav Steam Tube Dryer was developed to dry high moisture organic by-products such as brewer's and distiller's spent grain. Today, this dryer serves thousands of applications, drying and processing inorganic and organic chemicals and other bulk solid materials. The steam tube dryer generally operates at a lower temperature than other dryers and rotates at a slower speed. Material tumbles gently around the tubes which rotate with the shell, unlike the friction forces required by other types of dryers to process material. Consequently, it enjoys a longer life than most dryers and requires very little maintenance. Sakav Steam Tube Dryers have proved superior to other types of indirect-heat dryer installations in which hot gas, rather than steam, is used as the heat source. Maintenance savings alone have often prompted replacement of other dryer systems with the Steam Tube Dryer   The Sakav Continuous Seal Steam Tube Dryer offers tremendous advantages for solvent extraction or drying in an inert gas atmosphere. The CS unit's revolutionary design permits material to be processed in a positive or negative pressure atmosphere and alleviates product and gas leakage into or out of the dryer. The dryer is operated as a counterflow unit. Air moves in the opposite direction of material flow. Sweep gas flow is used only to exhaust vapor and other gases created by the heating process, not to dry material. Low sweep gas velocity through the dryer vastly reduces the amount of product entrained in the exhaust stream. During solvent extraction, this not only means significant savings in the size and cost of recovery equipment, but simplifies dust collection requirements and reduces the cost of equipment required to handle the task.

A DECADE OF EXPERIENCE SAKAV, established in 1985, has developed and supplied a wide range of SPRAY DRYING SYSTEMS to the Chemicals, Dyestuffs, Ceramics, Food, Polymers and Pharmaceutical Industries in India and Abroad. With its vast specializes experience, resources and innovative technical know-how, SAKAV offers the most appropriate systems for all Spray Drying requirements designed and delivered by Sakav incorporate practically every conceivable combination of system components to meet a variety of product requirements. THE SPRAY DRYING OPTION A spray drying system employs a single process to convert a solution/slurry into a powder. The liquid is atomized, in a specially designed Drying Chamber, into a stream of hot air to evaporate the solvent. The dry powder is then separated from the air stream. Sakav custom designs a system to suit the product quality, feed conditions, heating source available and the local environment norms. The chamber geometry, spray pattern and the air flow distribution have a decisive influence on the product characteristics.   Each system is a harmonious combination of individual process sections of Air Heating, Feeding, Atomization, Powder Collection and Dust Separation. The wide variation of combinations handled by SAKAV are given in the table below -   ROTARY ATOMISER SAKAV with its in-house design capabilities ha built and supplied a range of Rotary Disc Atomizer. These are belt driven units with standard electrical motors. A number of models are available with wheel diameters of 100mm to 350mm and are suitable for capacities from 5 lit/hr to 10,000 lit/hr Various configurations such as orifice, pin, vane with stainless steel and ceramic wear parts are available. A variety of lubrication systems starting from continuous drip to fully automatic forced lubrication systems can be provided. Speed variations are achieved by changed pulleys or variable frequency drivers. TEST FACILITY Fully equipped dedicated Pilot Spray Dryers are available for conducting trials on customers samples and simulation of ideal drying parameters for individual products. Assessment of their physical properties such as moisture content, approximate particle size distribution and bulk density. Testing is an on-going process and SAKAV has, over the years, built-up a large data base for a wide variety of products. THE CHAMBER OPTIONS The chamber configuration plays an important part in meeting the end product requirements. As is apparent from the table there is an endless number of possible combination. Some of these have been depicted below. FLAT ROOF This is the most widely used configuration of spray chamber with flat roof construction. Co-current swirling air flow pattern is used in conjunction with centrifugal atomization. Generally used for producing a uniform fine powder. Dry powder can be collected partly under the chamber and the fines from the cyclone. Alternatively a single point collection under the cyclone can be provided. Can be adapted for nozzle atomization with an add-on air distributor. TALL FORM - BUSTLE The standard Tall Form Bustle construction with co-current linearized air flow pattern is sued with pressure nozzle atomization systems. The dry product is usually coarser than centrifugal disc atomized product. The bustle construction enables separation of coarse fraction below the chamber and the fines can be collected from the cyclone. This configuration is deal where fines recycle is used for product agglomeration. TWO STAGE A configuration consisting of Tall Form Spray Chamber with a second stage Fluid Bed Dryer is used for special applications. This configuration is used for products requiring longer drying times which cannot be provided in Spray Chamber. This occurs when a coarse product has to be dried to a very low moisture content or when the product to be dried is hygroscopic in nature

FEATURES • HIGH AUTOMATION • LOW MAINTENANCE • CONTINUOUS OPERATION • LOW OPERATING COST OPERATING TEMPERATURE :- 60°C to 1OOO°C. CAPACITY :- 5 TPD TO 150 TPD SIZE & MOISTURE :- Capable of Handling different product particle size & moisturecontent. SYSTEM Drying / cooling is achieved by passing the material to be processed through a rotating cylinder through which also passes a current of tempered air. Lifters/flights or louvres in the case of rotary louvre dryer, are fitted to the Internal surface of the cylinder to give intimate contact between product and drying or cooling air stream. In Rotary Louvre dryers the material IS not lifted and dropped through the drying air stream, therefore less product breakdown occurs. Rotary Louvre dryers can also be arranged for multi-stage drying, or drying and cooling in one Unit. DRYER PRINCIPLE Co-current Flow Rotary Cascade Dryers, sticky and heat sensitive materials, since the wet material IS exposed to the highest temperature gases, the initial heat transfer rate is very high, rapidly evaporating surface moisture. The Immediate and dramatic fall in gas temperature prevents a sudden Increase in the matenal and shell temperatures. The final product is in contact with the lower temperature gases enabling the moisture content to be readily controlled thereby avoidrnq over-drying. Counter-Current Flow drying in a Rotary Cascade Dryer gives lower product moisture than co-current flow for a given inlet temperature. However, its use with heatsensitive rnatenals IS limited since the dryed product comes into contact with the heating medium at its highest temperature. It is suitable for application where an extremely low moisture content is required or where a higher product temperature is anadvantage. HEATING MEDIUM Gas. Diesel, oil, electric, stream. The drying gas are provided from either a direct fired furnace or an indirect heat exchanger within the range 100 to 1000 C using solid, gaseous or liquid fuel. Only products of combustion or indirectly heated gases enter the Rotary Cascade Dryer. This prevents surface contamination while reducing the risk of damage or fire when handeling more sensitive materials. A two fan balanced draught system IS used to provide the maximum degree of control & flexibility. In arrangements and the drying gases are provided by a locally mounted burner projecting the flame down the centre of the dryer through which the material cascades. This design gives even greater thermal efficiency due to the higher temperature differential, the direct flame contact and the radiation effect, when processing materials which can withstand high gas temperatures without deterioration. CONSTRUCTION Carbon, Stainless or custom alloy steel plate, with external reinforcing bands for fitting of tyres and drive rings. Flights and lifters or louvres are welded or bolted internally. Confifuration is determined by application. DRIVE Drum is rotated by an electric motor through V-belts, gearbox, pinion and either heavy duty chain to a chainwheel or spur gear drive ring bolted around the dryer drum. For high temperature operation, tangent plates are utilized to allow for differential expansion. CLOSURES & SEALS Ends of drum may be enclosed by carbon or alloy steel fabricated end plates or hood With Inlet/outlet chutes and suitable seals   Note : Dimensions and the other data of the Rotary Dryers depend on the material properties, water content. dryness, drying capacity, etc. The values of motor horsepower given in the table are those required to rotate the rotary dryer alone. The figures do not Include the horsepower requirements to operate the exhaust, burner material feeder etc.
