Dried & Tested — Proven, not Assumed.
Estimate industrial dryer capacity basis, dried output, water evaporation, heat requirement, airflow, fuel consumption, drying cost and indicative ROI from your process inputs. Use the result as an early engineering basis before pilot validation and final dryer sizing.
From feed moisture to discharge moisture.
Mass balance is the easy half — any spreadsheet does it. Heat load, air flow and fuel consumption are where a dryer gets sized right, or sized expensively wrong.

Note: The figures on this sheet are theoretical estimates based on the values entered and standard engineering assumptions. Actual heat load, air flow and fuel consumption can vary with the characteristics of the feed material (particle size, stickiness, bulk density and moisture variation), ambient and site conditions, utility quality, installation, and day-to-day operating and maintenance practices. Final dryer sizing and performance are confirmed only after a pilot trial at Gem Drytech's facility and a detailed techno-commercial proposal.
We'll send the complete dryer heat load calculations — mass balance, heat load, air flow and fuel consumption, plus the ROI if you run it — together with the Gem Drytech company profile. Nothing is downloadable from this page; the calculations reach you by email only.
By requesting the report you agree to the Terms of use, including that Gem Drytech Systems LLP may contact you about your enquiry. Figures are indicative and based on the values you entered; final sizing is confirmed by a pilot trial at our facility.
An industrial dryer calculation begins with the wet feed rate, inlet moisture and required outlet moisture. This tool conserves dry solids to estimate dried output and water evaporation, then develops a preliminary heat-load, airflow, fuel-consumption and drying-cost basis. The ROI section adds utility cost, raw-material cost for Product mode, recovery or product revenue and project investment to estimate indicative payback.
For preliminary dryer sizing, first define how much moisture must be removed. The calculator then develops the thermal and airflow basis needed to evaluate an industrial drying system. Final equipment dimensions and residence time depend on the real material and must be confirmed by detailed engineering.
The calculated evaporation and heat-load basis helps start equipment selection. The correct dryer type also depends on particle form, stickiness, heat sensitivity, residence time, throughput, product handling and utility availability.
Gem Drytech Systems LLP designs and manufactures industrial drying systems from Kolkata, India for food, chemical, pharmaceutical, sludge, agro-processing, biomass and related process industries. The calculator is intended to establish an early engineering basis; final selection is validated against the actual application.
It estimates mass balance, dried output, water evaporation, heat load, airflow and indicative operating and ROI values from the process inputs entered.
Yes. It provides an indicative engineering basis across a wide range of wet products and residues. Final equipment selection still depends on the actual material and process conditions.
No. The calculator is an early engineering tool. Final sizing and performance are confirmed through material evaluation, pilot testing where applicable and a written techno-commercial proposal.
The calculation conserves the dry solids between feed and discharge. Using the wet-feed rate, inlet moisture and target outlet moisture, it estimates the dried-material flow and the difference becomes the water evaporation load.
The preliminary heat-load basis includes sensible heating, material heating, latent heat for evaporating moisture and the selected heat-loss allowance. Air temperatures are then used to develop the indicative airflow and heater duty.
Yes. It converts heater duty into indicative hourly consumption for the available fuel options using the calorific-value basis and selected direct or indirect heating mode.
When Product is selected, the entered raw-material cost per kg is applied to the incoming feed quantity. Product revenue is then compared against raw-material and drying utility costs to calculate indicative annual net recovery, ROI and payback.
Through the Dried & Tested approach: material can be evaluated in the pilot facility so drying behaviour and process data are reviewed before final equipment selection.
