METHOD FOR DRYING LAUNDRY AND DRYER

A method for providing fresh air fed through a fan to a burner of a dryer, thereby charging the burner, when the dryer is operated with recirculating air. In commercial dryers in which the drying air is heated by a burner, it is customary to reuse the moist air leaving a drum containing the laundry to be dried as recirculating air. The recirculating air component is increased with increasing drying of the laundry. At the end of the drying operation, when the moist air no longer contains as much moisture as at the start, the moist air is used as recirculating air. The burner then no longer gets enough combustion air, which leads to an incomplete combustion. The dryer can be operated with a higher recirculating air component, an optimal combustion being guaranteed through the charging of the burner with fresh air.

METHOD FOR EFFICIENT AND EFFECTIVE DRYING

Hot air drying is an intensive energy consuming process, 5000-8000 kJ per kg of water. More efficient processes produce low drying rates or cannot totally dry the product because they do not integrate the four drying phases, warm up, constant drying, falling drying and aeration and do not handle dripping. To reduce the energy consumption, the exhausted mix of air and vapor is used as working fluid to drive each phase, and the dripping is collected before it goes back to the product. This fluid is compressed inside of a heat-exchanger to heat the product; however, the mix proportion, vapor and air, changes on each phase. For warm up phase, the working fluid is either hot air or condensed water; in constant phase, it is mostly vapor; in falling phase, it changes from vapor to air; and for aeration, it is air. Inlet and outlet valves control these proportions. 1. A method for totally or partially drying a product in a drying equipment , wherein the method is driven by one or more compressors acting on an air/vapor mix released by the product , integrates the drying phases of (i) Warming up , (ii) Constant drying , (iii) Falling drying , and (iv) Aeration , and controls a dripping formed in the drying equipment , comprising the steps of:a. reducing the pressure inside the drying equipment by the action of the compressor.b. sucking up ambient air into the drying equipment through an air inlet;c. warming up said air and the product with a heat exchanger which evaporates the moisture in the product, releasing the air/vapor mix;d. compressing the air/vapor mix released by the product by means of the compressor which increases its temperature and its thermal energy;e. transferring the thermal energy from the compressed mix inside the heat exchanger to the product and air on the other side of the heat exchanger, which reduces the mix temperature, condensates most of its vapor and warms up the product and the air on the other side of the heat exchanger; generating an air/vapor ...

RAPID COMPRESSION APPARATUS FOR TREATMENT OF MOISTURE-CONTAINING BIO-MATERIAL

An apparatus, a system, and a method for heat treating a moisture-containing or water-laden material are provided. The heat treatment can be drying for dehydration, gasification, or full carbonization. The system comprises a feeding mechanism, and a rapid compression (RCU)apparatus having a screw, a barrel, and one or more flow disrupters. The system can further include a reflux condenser, an aftercooler stage, a second condenser for particle filtering, and an exit mechanism. The one or more flow disrupters are located on an inner surface of the barrel and projects into the passageway created by the screw and the barrel. The screw is sized to fit within the barrel such that flow disrupter does not contact the screw. The one or more flow disrupters cause the water-laden material to fold over onto its self, thereby, allowing for the occurrence of more uniform drying. 1. A method of treating a moisture-containing or water-laden material to produce a bio-product , the method comprising the steps of:providing a moisture-containing or water-laden material; an RCU apparatus having a compression screw, a barrel, and one or more flow disrupters mounted on an interior surface of the barrel positioned in a passageway formed between the screw and the interior surface of the barrel, the screw operable to rotate at a speed to produce friction and compression to generate a desired elevated temperature within the barrel; and', 'a feeding mechanism adapted to receive the material and feed the material to the RCU apparatus,, 'providing a rapid compression unit (RCU) system includingfeeding the moisture-containing or water-laden material to the RCU system using the feeding mechanism;mixing and heating the moisture-containing or water laden material in RCU apparatus such that the moisture-containing or water laden material separates into at least steam and a bio-product material; andremoving the the bio-product material from the RCU apparatus.2. The method according to claim 1 , ...

Drying of Organic Materials

This invention relates to a method and apparatus for drying organic material using the energy contained in the organic material to be dried to drive the drying process. The organic material could be sewage sludge, food scraps, manure, wood, bagasse etc. The latent heat of evaporation is recovered through the use of a heat pump mechanism. This allows for the retention of a majority of the heat within the system, allowing optimal drying conditions to be maintained throughout the drying process. 1. A method for drying particulate organic biodegradable material comprising of the following steps:a. Blending said organic material with other materials to produce an organic mix that generates biological activity in the presence of oxygen.b. Putting said mix in contact with a stream of gas containing oxygen and allowing it to decompose biologically, generating heat.c. Circulating said gas stream across the decomposing blended mixture and incorporating water vapor and other gases.d. Conveying the vapor laden, gas stream to a separate condensing stage where the water vapor is condensed, reducing the moisture content of the gas stream and transferring the heat of condensation to a condensing surface and forming a dried gas stream.e. Removing the condensed liquid from the condensation stagef. Transferring at least a portion of the heat of condensation from the condensing surface to the same or different organic decomposing mix.2. The method of where at least a portion of the heat of condensation is transferred directly from the condensing surface to the same or different blended organic decomposing mixture.3. The method of where the dried gas stream is conveyed to a separate stage where at least a portion of the heat of condensation is transferred to said gas stream and said gas stream is renamed to me same or different blended organic decomposing mix to repeat the cycle.4. The method of where a different gas stream is conveyed to a separate stage where at least a portion of the ...

Continuous-flow dryer comprising a first and a second section

A continuous-flow dryer for drying a material by hot air is provided with a first and a second section, through which the material is passed successively in a transport direction. It includes a fresh air supply device, an exhaust air recirculation device for removing exhaust air and recirculating it as supply air, and a heat exchanger, through which fresh air and exhaust air are led, for transferring waste heat of the exhaust air into the fresh air. With the exhaust air recirculation device a first part of the exhaust air is removed from the first section and recirculated as supply air directly into the first section. Furthermore, a second part of the exhaust air is removed from the first section, led through the heat exchanger, and recirculated as supply air into the first section. The fresh air supply device supplies fresh air as supply air into the second section. 1101424.
