2 New drying technology C 6 the ultimate drying technology Smart drying technology : continuous flow and reverse counter current C 1 The lower rotating plate is loaded with the material to be dried UP LOWER LEVEL DRYG The material is rotated by UP The material to be dried is transferred towards the upper plate by a bucket elevator or a worm drive system HIGHER LEVEL DRYG The material is rotated 360 by the upper rotating plate, moving in the opposite direction to that of the lower level plate. This exclusive technology ensures better distribution of heat and greater efficiency than other hot air drying techniques. 5 The dried material is exited towards the packaging or storage area. DRYER ONE surpasses traditional hot-air drying methods in thermal efficiency, flexibility and more, DOWN 8 6 CONVEYOR BELT TUNNEL DRYER RACK TUNNEL DRYER ROTARY DRUM DRYER VERTICAL DRYER HOT AIR FLOW The hot air is sucked from the top to the bottom creating a counter current. It successively crosses the higher and lower level plates. The hot air flow keeps the material being dried on the rotating plates and drastically reduces dust dispersion. If necessary, filters suitable for residual particles can be installed at the final stage of the process. 7 RETRIEVAL AND EXPULSION OF AIR SATURATED WITH MOISTURE After passing through the two plates the saturated air is pushed upwards for expulsion. EXCLUSIVE TECHNOLOGY PATENTED BY TECHNIC ONE

3 DRYER ONE opens up new possibilities for the drying of forest wood, agricultural and biomass products DRYER ONE is a drying machine, designed to meet the increasingly high demands for dryers : increasing volumes, higher productivity requirements, higher quality standards, cost reduction, energy saving, flexibility, reduced particle emissions and decreased VOCs pollution. DRYER ONE dryers can easily adapt to all situations, especially when used as an annexed unit to a cogeneration plants. Access doors allow users to easily observe the drying process and access the inside. 3 UP 1 Direct access to the mechanics from the outside and through the central technical area. 5 The material being dried is exposed to the hot air flow with a uniform layer and an adjustable thickness. The rotating plate, whose speed can be regulated, directs the material towards the worm drive of evacuation. High pressure fan to cross the two layers. The 2m gaps between the plates make it easy to carry out checks and maintenance inside the dryer. The heat exchangers placed in the upper part of the dryer enable to heat the air coming from the outside.

4 The DRYER ONE unit, powered by a cogeneration plant, is the perfect solution for drying forest and agricultural products, as well as optimising waste Multi-purpose drying Hot air is drawn from a cogeneration unit. Water exit C C C 0-25 C The heat exchanger converts the heat of the hot water into air at room temperature. The heated air is then pumped into the dryer. Wood waste Sawdust Wood shavings The incoming air is dry and hot (between 60 and 90 C). The reverse counter-current air flow (moving from the top to the bottom of the dryer) presses the material onto the rotating plates and largely prevents dust dispersal. Brewer s grain Corn gluten The second rotating plate completes the drying process and allows the hot air to absorb residual moisture. The first rotating plate gradually and partially evaporates the moisture UP Material is transferred from the lower plate to the higher plate via a bucket elevator or a worm drive. During the transfer, the material is rotated and mixed, providing better quality and more even drying. Barley Maize Soya C 5 AIR BOILER 110 C Oil seed rape 3 Lentils The outgoing cooled air (25 to 30 C), almost completely saturated with moisture, is evacuated via the chimney Hot air can also be produced by an auxiliary boiler, powered by the client s choice of gas, LPG.

5 ROTATION OF MATERIAL Each drying plate is equipped with a worm drive which thoroughly rotates and mixes the material to be dried. This process provides more even and better quality drying. Rotating plates Strong, durable, simple and reliable ROTATG METAL PLATES The rotating plates have a stainless steel grated structure with a planarity greater than that of conveyor belts. They have high resistance to load stress and corrosion. The grated structure is divided into segments of equal size, making it easier to carry out maintenance work in the space of just a few minutes. ROTATION SYSTEM Each rotating plate is activated by a gearmotor which ensures a constant rotation speed and complete reliability. Waste extracted by suction. NOVATIVE CLEANG SYSTEM The drying surfaces are cleaned via an automated process with a tool using both high pressure injectors and suction, ensuring full and even cleaning. Cleaning carried out with hot water under high pressure. PLATE COVERGS The rotating plates are covered with a highly resistant synthetic grooved surface or stainless steel perforated sheeting. The load loss of the material to be dried is lower than that of the covering, leading to better diffusion of the hot air flow across the whole surface. Moisture can be extracted gradually, without thermal shock. The more even humidity level is one of the main advantages of DRYER ONE. The coverings can easily and quickly be replaced. Discharge recuperated from water run-off. Used water extracted by suction.

CONSISTENT QUALITY The exclusive DRYER ONE technology ensures a more even humidity level at the end of the process, as well as protecting the integrity of the material being dried. > no thermal shock > no load stress > no friction stress > no stress on the material FANCIAL BENEFITS > small ground surface area occupation (40-6 saving) > no individual building needed > shallow foundations > quicker amortisation thanks to flexibility of use ENERGY CONSUMPTION > energy savings of 3 (0.85 kw / l. evaporated water) thanks to the ingenuity of the process, the mixing of the material, the high quality thermal insulation and so on. > electricity consumed by the drive system is minimal MATENANCE > simple, strong and reliable mechanics. Low risk of breakdown > technology which reduces the production of dust and lowers filtration needs > easy and low cost maintenance HMI CONTROLS : SIMPLE AND EFFICIENT The control cabinet regulates the drying process automatically in accordance with the type of material being dried, the humidity rate measured on entry and the desired humidity rate at the end of the process. Each stage and variable in the drying process can be directly accessed via the HMI (Human Machine Interface) control screen. MONITOR THE PROCESS ONLE Sensors in different parts of the dryer transmit data back to the control cabinet about temperature and humidity at entry, during the process and at exit. The user can monitor these variables as the process unfolds and can make adjustments during the process. This is an exclusive and significant advantage which ensures that the desired humidity rate is achieved by the time the process comes to an end. Users can also access a process log with graphs. The database can be exported to a computerized unit. MIMISE PARTICLE EMISSIONS Conventional dryers emit large amounts of dust, which must then be absorbed via a costly filtration process. The exclusive DRYER ONE technology provides an optimal, ecological solution. The hot air flow keeps the material being dried on the rotating plates and drastically reduces dust dispersion. If necessary, residual dust can be filtered at the final stage of the process.. This added value is essential for compliance with increasingly stringent environmental regulations. MORE ENERGY EFFICIENT DRYER ONE dryers with isolated exterior walls consume less energy than other drying technologies. ENERGY RECOVERY The use of residual energy from another installation (cogeneration) is an innovative solution for energy recovery, which also reduces energy consumption and environmental impact. WORKFORCE > automation of several functions > easy and rapid adjustments > ease of access to the inside and outside of the dryer TOUCH SCREEN This dryer uses touch screen technology. Tabs and variables are chosen via the touch screen, making it as easy as using a Smartphone. FLEXIBILITY EASY TO ADAPT

7 Simplified mechanics Insulation of exterior walls Gateways and access doors at all levels Easy access components The 1.5 to 2m gaps between the plates make it easy to access and move around inside the dryer, which has interior lighting. No noise pollution thanks to the fans being located inside the dryer together with insulated external walls. Direct access to almost all mechanical components from the exterior. Scraper for recycling fine particles. The DRYER ONE is equipped with insulating metal silo walls. The compact size and circular shape of the unit offers several advantages : > small ground surface area occupation > can be installed indoors or outdoors > installation requires a loading crane > stable and resistant to wind Due to its low weight, only shallow foundations are required (20cm reinforced concrete). Simple maintenance DRYER ONE dryers have simple mechanics with only a few moving parts. Essentially the DRYER ONE drive system requires only two geared motors of few kw per rotating plate to power the racks. This has several advantages : much lower electricity consumption during locomotion, simpler maintenance, silence when in use, very low risk of production incidents,... Most testing and maintenance tasks can be carried out quickly, without generally having to stop production.
