摘要： The invention relates to the thermal treatment of flowable material using heated contact surfaces in a fluidized bed. Known processes use a gas, often air, to fluidize the bed. This imposes limits on the temperatures that can be allowed to be reached as higher temperatures can cause the material to be treated to burn. It also often produces sterilization of the material. Further there is the problem of disposal of the gases generated in the treatment process. In an attempt to alleviate these problems, the present invention proposes a process generally of the above kind but in which the fluidizing gas comprises gases generated in the bed itself. This is economical as it reduces the heat losses, environmentally desirable as it reduces the amount of gas discharge and more efficient as these gases are generally inert, thus enabling higher temperatures to be generated in the bed without risk of the material burning, thus also facilitating sterilization of the material.
摘要翻译：本发明涉及使用流化床中的加热接触表面对可流动材料的热处理。已知的方法使用气体，通常是空气来使床流化。这对可以允许达到的温度施加限制，因为较高的温度可导致材料被处理燃烧。它也经常对材料进行灭菌。此外，存在处理过程中产生的气体的问题。为了减轻这些问题，本发明提出了一种上述类型的方法，其中流化气体包括在床本身中产生的气体。这是经济的，因为它减少了热损失，因为它减少了气体排放的量并且由于这些气体通常是惰性的而更有效，所以在环境上是有希望的，因此能够在床上产生更高的温度而没有材料燃烧的风险，因此也有助于灭菌材料。

摘要： The invention relates to a method of drying with hot air where the drying is divided into at least two partial processes, in parallel or in series with each other, and the circulation flows of the two partial processes are conditioned to substantially different wet temperature levels, and the spent air in the partial process with higher wet temperature is heat exchanged with the circulation air in the partial process with lower wet temperature, in combination with that the spent air flows from the two partial processes thereafter are mixed with each other and caused to pass a heat exchanger common for the processes in order to preheat the supply air to the partial process with low wet temperature and after the passage through the heat exchanger to partially constitute supply air for the partial process with high wet temperature.

摘要： An apparatus for circulating high temperature air at approximately 20,000 cubic feet per minute through an enclosed room in which fruit are stacked in sweat boxes on pallets. A fan draws the heated air from a heat source into a plurality of inlet ports at the bottom of the housing. A damper position at each of the inlet ports deflects the hot air entering the drying room upwardly between the stacks of containers in the drying room and the corresponding side wall of the housing towards said top, the hot air passing between the top of the stacks of containers in the room and the top of the housing, and down between the stacks of containers in the room and the opposite side wall of the housing. A recirculating port in the first-named side wall through which the fan draws the air from the opposite side wall between the individual containers in the stacks and across the fruit within the containers and back to the inlet of said source.

摘要： An apparatus for starting a hot air recirculating furnace system. Reduced power is applied to the motor which drives the recirculating fan to cause the motor to turn at a reduced speed. The furnace is ignited during the application of the reduced power to the motor. As the temperature in the furnace increases, the warmer air recirculates and the load on the fan decreases. The power supplied to the fan motor is then increased, thereby increasing its speed as a function of the increased temperature as sensed by a thermostat in the furnace system. Full power is applied to the fan motor when the sensed temperature reaches a selected desired maximum. The apparatus and the method eliminate squeal of the belt which drives the fan and reduce wear common to those techniques which apply full voltage to the recirculating fan at furnace start-up. Also, this system reaches the desired operating temperature more quickly than prior art systems as a result of a reduced recirculating airflow during a longer acceleration period.
摘要翻译：一种用于启动热空气再循环炉系统的装置。对驱动再循环风扇的电动机施加减小的功率，以使电动机以降低的速度转动。在将电力降低到电机的过程中，炉子被点燃。随着炉中的温度升高，较暖的空气再循环并且风扇上的负载减小。然后提供给风扇马达的功率增加，从而随着炉系统中的恒温器感测到的升高的温度而增加其速度。当感测到的温度达到所选择的最大值时，将对风扇电机施加全部功率。该装置和方法消除了驱动风扇的带的尖叫，并降低了在炉启动时向再循环风扇施加全电压的技术所共有的磨损。此外，由于在较长的加速期间减少的循环气流，该系统比现有技术的系统更快地达到期望的操作温度。

摘要： Method and apparatus are described for the production of solid fuel and steam by drying moisture-containing solids, such as refuse and sludge cakes, in a multi-stage heating zone by using the moisture-containing solids as the feed-water in a direct contact countercurrent flow pressurized boiler. After vaporizing the bulk of the moisture in the heating zone of the boiler, the solid residue is further dried in a multi-stage flashing zone. From the upper end of the heating zone is removed a nearly saturated steam including the water vapor evaporated from the moisture-contained solids by the heat of cooling of the introduced superheated steam. A portion of the removed steam equal to the vaporized moisture is heated and then directed to a turbine, generating all the power required to operate the system. The bulk of the removed steam equal to the introduced superheated steam is compressed, reheated and recycled through the heating zone. The dried solid is removed at the lower end of the flashing zone and is incinerated, and the recovered heat is utilized to supply the heat required for said drying, and to produce saturated steam for heating purposes, or superheated steam for power generation.In the latter case the heat of condensation of the turbine exhaust steam is utilized advantageously as a heat source in a distillation plant for fresh water production.

摘要： A furnace having a burner at one end and having air openings adjacent to the burner is coupled at its other ends to a rotary drum dryer for alfalfa or other moist products which are to be dried. A fan is coupled to the outlet end of the dryer to draw the moist product and the hot gases from the furnace through the dryer. A centrifugal cyclonic collector is coupled to the outlet of the fan, and a significant portion of the exhaust gases from the collector is recycled to a hood which covers the burner and air openings at an end of the furnace. The recycled exhaust gases provide substantially all of the drying medium for the dryer.

摘要： A continuous vacuum drier for removing moisture from solid synthetic resins in granular form prior to manufacturing into finished products. The synthetic resinous material is continuously supplied to the top of a closed drying hopper and removed from the bottom of the hopper. In one embodiment air withdrawn from the top of the hopper is circulated through a heater and is returned to the bottom of the hopper, where it travels upwardly through the synthetic resinous material in the hopper. In a second embodiment, air is withdrawn from the bottom of the hopper and is returned to the top of the hopper, where it travels downwardly through the synthetic resinous material in the hopper. The circulated air and the material in the hopper are heated as they pass grids of pipes which are heated by circulated hot water. In both embodiments, a vacuum pump is connected to reduce the air pressure in the system for increasing the efficiency of the drier and for causing the hopper to automatically fill with material to a predetermined level from a primary feeder hopper. A small amount of dry air may be introduced into the hopper for carrying off evaporated moisture. The dry material is fed by gravity from the bottom of the hopper to a processor.

摘要： In a drying and curing oven heated air is introduced through the lower open end of a drying compartment and rises and makes intimate contact with an article supported in said compartment, and used air is exhausted through one or more ducts extending from a closed top of the compartment. If desired, the exhausted used air is discharged to a burner for heating incoming drying air and is recirculated with the latter to said drying compartment.
