Our Paddle Dryer is an indirect-heated machine with well-engineered insulation which can achieve thermal efficiencies up to 98%.

The Heat Exchanger is used to generate hot air via a centrifugal blower which will help to avoid condensation of moisture inside the paddle dryer.

The required steam pressure is decided based on multiple factors in our Paddle Dryer design process like the temperature limits of the product to be dried, the availability of steam pressure of the existing plant, CapEx or OpEx cost prioritization.

The required thermic fluid temperature is decided based on multiple factors in our Paddle Dryer design process like the temperature limits of the product to be dried,the availability of temperature of the existing plant, CapEx or OpEx cost prioritization.

Yes, we have a pilot plant of 50 Kg/hr in which we can offer you a trial at your plant with minimal cost to check your product viability and project feasibility

The space requirement of the Paddle Dryer will depend on various factors like the hourly feed rate, initial moisture of the feed, final required mositure for your dried product, available steam pressure or thermic fluid temperature at the site. You can contact our expert application engineers for figuring out your exact solution.

We can design the paddle dryer for other process like Heating, Calcing, Solvent Stripping, Crystallizing, Reacting, Cooling, etc.

Our Proposal Engineers can quickly provide an estimate for your plant. We need to know your feed input rate in the dryer, the feed moisture and the desired product characteristics. You can find the link to the questionnaire here. Kindly complete the questionnaire and we will respond as soon as possible with a customized techno-commercial offer. Feel free to talk to out expert.

The most commonly used heat transfer medium is Steam. Other than that, thermic fluid, biogas, flu-gas, etc. can be used; provided the required technicalities are met.

The total energy used by our Paddle Dryer is calculated based on all the factors like the initial moisture and the final moisture as well as the feed and discharge temperatures.

The Cost of drying sludge depends on two factors:

1. The Cost of Heating Medium(i.e., Cost of 1 kg of steam in Rs).
2. The Cost of Power Used(i.e., cost of electricity in KWh).

The cost of drying 1 Kg feed is

(Total Consumption of Feed X Cost of Steam per Kg) + (Total Power Consumption X cost of Power per KWh)/(Total Feed Input in Kg/hr)

If the Sludge has moisture content in it, we can dry the sludge to reduce its moisture to a minimal level resulting into a reduced volume of sludge to dispose and handle which in turn converts into unimaginable savings.
