United States
We engineer and build spray dryers, falling film evaporators and complete drying lines, ship them to your plant and supervise installation and start-up. Before you invest, we test your product at our pilot plant.
The engineers who size your dryer or evaporator are the ones you talk to, from the trial to start-up.
Standard series adapted to your feed, solids and final moisture, or equipment built to order when no standard model fits.
Spray, convective, rotary and DIC drying, granulation and laboratory at our pilot plant, with your real sample.
Multiple-effect evaporation with thermal vapour recompression before drying cuts steam and gas use.
The same process engineering as the large OEMs, with a leaner structure and direct decisions.
Video calls, WhatsApp and site visits with the project engineers, plus spare parts.
Milk and whey powder, plant proteins, honey and fruit powders, flavours and encapsulated ingredients, chemicals.
Spray dryer →Milk, whey, juices, extracts, syrups and effluents, from 1 to 6 effects with TVR.
Falling film evaporator →Starches, fibres, filter cakes, minerals, fertilisers and by-products.
Flash dryer →Process development and first batches before the industrial investment.
Pilot plant →Water to evaporate, powder output and savings from pre-concentration.
Open the calculator →Projects by WITech D&E and SEI Contreras, the company we continue.
Instant coffee plant: four-effect falling film evaporator with thermal vapour recompression and a tall-form spray dryer with high-pressure nozzles, vibrating fluid bed and fines return.
Three-effect evaporator to recover soy process streams: falling film and forced circulation with double thermal recompression, automation and CIP, from 3 to 48 % solids.
Spray dryer for salmon hydrolysate: rotary atomiser, direct gas-fired air heater, vibrating fluid bed, fines return and Venturi scrubber, plus a new chamber cone.
Four-effect falling film evaporator with double thermal recompression, cooling towers and PLC/HMI automation for a biological raw material, developed from pilot trials.
Turnkey pea protein isolate plant: spray dryer with vibrating fluid bed, flash dryer, three-effect evaporator, UHT, CIP and automation.
Turnkey apple juice concentrate plant with a three-effect evaporator and thermal vapour recompression.
Quillaja extract evaporator for BASF, the German chemical company: two-effect falling film unit with thermal vapour recompression and recirculation, from 5 to 40 % solids.
Self-inertising spray dryer for microencapsulated sulphur: closed loop with a self-inert atmosphere (O₂ < 4 %) and no nitrogen consumption. In 2022, a mass and energy balance study to raise its capacity.
Process water heaters for instant coffee extraction: two shell-and-tube heat exchangers designed to TEMA and ASME, with steam temperature control and condensate units, exported for the extraction line.
You ship your product to our pilot plant and we measure how it behaves before the design.
We size the line from measured data and send the technical and commercial proposal.
We build the equipment and ship it to your plant.
We supervise installation, commission the line and train your operators, then support you after start-up.
Yes. We engineer and build in Argentina, ship the equipment to your plant and supervise installation and start-up, with an English-speaking engineering team.
Yes. You ship a sample to our pilot plant near Buenos Aires and receive a report with the process conditions and a sample of the dried or concentrated product. The industrial line is sized from those measured figures.
We agree the design codes, material certificates, electrical standards and documentation your project requires with your engineering team at the quotation stage.
Spray dryers up to 1,500 kg/h of water evaporation, falling film evaporators up to 75,000 kg/h, flash and rotary dryers, forced circulation evaporators, bag filters, scrubbers and fluid beds, plus upgrades of installed equipment from any manufacturer.
With the product data and the capacity you are after we answer within 24 business hours, with a first technical assessment of the line that fits your plant.
