The Ring Dryer is a special development of the Flash Dryer Incorporating an internal airborne recycle For greatly improved operation and efficiency. Our designed of Ring Drying System consists of a “manifold” or “internal classification which differentiate it from flash dryer The Internal ‘circulation in the Ring Dryer, which is of the manifold, a special centrifugal classifier designed to separate dry and fine particles.
While holding large moist particles in prolonged circulation this enables the Ring Dryer to process many materials that were earlier considered difficult to dried with the help of a Flash Dryer efficiently and also to obtain exceptionally good control of the final product moisture content.
2. Spray Dryer
We are leading Manufacturer of customized Spray Dryer as per Client and process requirement.
Spray drying is considered a powerful technological process since it brings feasibility to the production of free-flowing particles with well-defined particle size. The scalability and the cost-effectiveness of this manufacturing process in obtaining dried particles in submicron-to-micron scale favors an increasing variety of applications within the food, chemical, polymeric, pharmaceutical, biotechnology and medical industries.
Spray drying is a method of producing dry powder from a liquid or slurry by rapidly drying with hot gas using a pressure atomizer which converts the pressure energy is converted into kinetic energy and dispersed as droplets at a high-speed discharge.
3. Flash Dryer
MKS Flash Dryer is a pneumatic system which is efficient and inexpensive drying technology.
Our flash dryer system is an inexpensive solution to drying powders and granular materials, and is designed for high moisture materials with a constant-rate drying zone and can use higher gas temperatures, versus other dryer types, because the material retention time is very short. Drying takes place in a matter of seconds.
The pneumatic or ‘flash’ dryer’ is a method suited for products that dry rapidly owing to the easy removal of free moisture or where any required diffusion to the surface occurs readily. These types of dryer are mainly used for drying of heat sensitive or easily oxidizable materials. The wet materials that are to be dried are passed into a high-temperature air stream (or other gas) that carries it to a hammer mill or high-speed agitator, which conveys it through a drying duct where high heat and mass transfer rates rapidly dry the product. Applications include the drying of filter cakes, crystals, granules, pastes, sludge’s and slurries, in fact almost any material where a powdered product is required. The drying rate is very high for these dryers, but the temperature does not rise much because of the short residence time.
4. Fluidized Bed Dryer
MKS is a Specialized Manufacturer of Fluidized bed dryers as per Client and process requirement.
We design Fluidized Bed dryers for food and dairy, chemical and pharmaceutical industries. Fluidized bed drying is the optimal method for controlled, gentle and even drying of wet solids. The intensive heat/mass exchange of the fluidized bed product makes this method particularly effective and time-saving. The technology is also suitable for post-drying of spray granulated or extruded products with very low residual moisture.
This technology is applied for drying and/or cooling for production of agglomerates and granulates from fine powders.
Our Fluid Bed dryers are all designed for our clients’ specific purposes, matching the industry specific standards and requirements.
5. ROTARY (BUNDLE) Dryer
MKS is one of the best Rotary/Bundle dryer specialists in INDIA.
Rotary dryer is a kind of drying equipment for processing, vast range of, large quantities of materials. It has characteristics of reliable operation, large operation flexibility, strong adaptability, large processing capacity, strong adaptability of materials, drying of various materials.
Working Principle:
The rotary dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The dryer is a cylinder that is slightly inclined from the horizontal direction. The material is added from the higher end. The high-temperature heat source and the material flow parallelly or counter-flow into the cylinder.
As the cylinder rotates, the material flows to the lower end. The lifting board on the inner wall of the cylinder lifts up and drops down the material, so that the contact surface of the material and the air flow is increased to increase the drying rate and promote the advancement of the material. The dried product exits the dryer from the lower end.
Evaporators for Pharmaceuticals Industry
We are leading and expert manufacturer of Evaporator Plants for applications related following industries, Beverage, Pharmaceuticals, Automobile, Dairy ,Water Treatment ZLD Glucose Industries, Starch industries etc.
How Evaporator Work-:
Evaporators are used in industries to concentrate the product through the process of evaporate water . Evaporators can be in range of single effect to seven effects which depends upon the volume of product to be process through the evaporators.
The technology is based on basic principle of reduction of quantity by concentrating the Product and subsequently separation of water. Product effluent is fed to the evaporator to concentrate up to concentrate up to 30% to 90% solids concentration. The total process is under vacuum and the vapors generated in the system are re-used to economize steam consumption in multiple effect evaporation system with the help of thermal vapor recompression system. The thermal vapor recompression use vapors generated in the evaporator and compressed it by steam and the compressed vapors are used as heating medium in the evaporator, reuse of vapors as a heating media reduces the steam consumption makes evaporators much economical than other traditional methods of evaporation .

1. Falling Film Evaporator
In Falling Film Evaporators the liquid flows downwards in the form of a film along with the vapors at the core in a parallel flow. The film mechanism and low residence time makes this evaporator ideally suited to heat sensitive non-salting and non-crystallizing solutions.
The liquid to be evaporated is initially pre heated to the boiling temperature and enters the heating tubes via distribution plates in the top bonnet of the evaporator.
In these evaporators sufficient wetting of the heating surface is very important for the heat economy and trouble free operation. The wetting rates can be increased by extending or splitting the individual evaporator effects.
Falling Film Evaporators can be particularly useful when the temperature difference between the liquid to be evaporated and the heating media is low.
2. Force Circulation Evaporators
Forced Circulation Evaporators are short tube evaporators and are ideally used when the boiling of feed liquid on the heating surfaces is to be avoided due to the salting and fouling characteristics of the liquid. Hence in these evaporators the flow velocity in the tubes is kept very high.
In these evaporators the liquid is circulated at high velocities in the tubes of the heat exchanger while steam is provided in the chest. This liquid is partially evaporated when the pressure is reduced in the vapor-liquid separator to the corresponding boiling temperature. High volume, low head axial flow circulation pumps are used for recirculating the crystal laden slurry in the evaporator and hence the operation of this evaporator is independent of the temperature difference. In the crystallizing operation crystals can be separated from the crystallizing slurry by adjusting the velocity of the circulating stream. These evaporators are ideal for handling liquors with high viscosity or which have a tendency to salt and scale during evaporation.
Features :
- Suitable for widest variety of evaporator applications.
- Ideal for crystallizing operation.
- High heat transfer coefficients. Positive circulation.
- Freedom from salting, scaling and fouling.
- Suitable for corrosive and viscous solutions.
3. Batch Evaporators
Batch evaporators are filled with the dilute material, heat is applied, and the material is gradually concentrated to the desired point by the application of heat and removal of vapors.
Additional dilute material might be added as the concentration occurs to replenish the evaporated liquid to a given level. Since each gallon of dilute material brings some solids with it into the evaporator, the evaporator eventually achieves the final solids concentration.
4. Scraped Surface Evaporator
This Evaporator Usually selected for products which are highly viscous or in paste / syrup forms products having a tendency to scale or salt out during evaporation can also be handled in this evaporator.
The rotating blades of these evaporators ensure that no material stays on the heat transfer surface for long duration thus preventing thermal degradation.
The liquid flow can be bottom to top or top to bottom. This flow pattern depends on the fluid properties, chances of scale or crystal formation. This system can be used along with the falling film or forced circulation evaporators as last finisher stage.
5. Wiped Film Evaporators
These WFE evaporators have found a niche in difficult evaporation operations. Though this style evaporator can be used in almost any application, the WFE excels in distillation steps where products are heat sensitive, viscous, tend to foul heated surfaces, or are high temperature boiling.
Wiped Film Evaporators are operating in plants world wide. Wiped Film Evaporators can be installed in a variety of configurations. WFEs with internal condensers are called short path evaporators and can operate under high vacuum.
Wiped Film Evaporators without internal condensers are called top vapor outlet (TVO) and employed as column reboilers or in very dirty applications.
6. Thin Film Evaporators
With Thin Film Distillation, a substantial decrease of boiling temperature is obtained by reducing the operating pressure. This allows thermal separation of products that would be destroyed by conventional vacuum distillation (pot still or distillation column) because of the necessary high temperatures and long residence time.
In a Thin Film Evaporator the raw material is heated up on the internal surface of a heated tube until the lower boiling component starts to evaporate. These vapors are then liquefied on the cold tubes of a condenser. In simple thin film evaporator design the condenser is located outside but as close to the evaporator as possible.
Advantages for thin film evaporator
- Small pressure losing
- Big diathermanous coefficient,
- high evaporating efficiency
- Low evaporating temperature
- Short heating time Strong adaptability
- Easy to operate
