    The invention relates to a method for obtaining dehumidified biomass, in particular of algae and / or microorganisms, for example after a harvesting process of the algae and / or microorganisms from a suspension consisting of nutrient solution, in particular in a breeding and production or hydroculturing. Furthermore, the invention also relates to a device for carrying out the method.
    Methods and systems for drying crops are known in many variations and preferably adapted to the crop.
    Thus, from DE 94 04 451 U1 a belt dryer with a arranged in a closed drying space wire belt on which the Trocknungsgut is promoted. In this case, the screen belt is acted upon from above with supplied dry air and the exhaust air occurring during the drying process is sucked off below the screen belt via a suction fan. To clean the exhaust air dust filter and filter elements are provided below the screen belt.
    Furthermore, from DE 43 01 993 A1 discloses a plant for drying crops, especially grass, stalk and leaf material known.
    From DE 10 2010 017 097 A1 a drying plant and a method for biomass and / or sludge is known. In this plant, the waste heat from a biogas plant is used for drying. This waste heat is supported by solar heat recovery. The dried biomass material is available as fuel and certainly brings good environmental compatibility.
    Furthermore, EP 2 848 883 A1 discloses a belt drying system with a drying belt for drying dry material, such as sawdust.
    The object of the invention is to provide a method of the initially cited type which on the one hand avoids the disadvantages of the known methods and devices and which is suitable for drying biomass, in particular algae and / or microorganisms, in a continuous, efficient and economical harvesting process.
    The method according to the invention is characterized in that the concentrated biomass present, preferably by the harvesting process, in particular the concentrated algae or microorganism suspension is distributed on a preferably endless drying belt, that the biomass distributed on the drying belt is exposed to heated air the heating of the air via the sun and / or an air heater in a closed system, that the drying process is carried out until a residual moisture is reached, wherein the dehumidified biomass adheres to the drying end in powdered and / or flake form on the drying belt and that these powder - And / or flocculent form of the biomass is separated by a scraping or Abkratzkante from the conveyor belt and collected in a collecting container. With the invention it is possible for the first time to dry the freshly harvested and concentrated biomass, in particular the concentrated algae or microorganism suspension, ideally immediately after harvesting, maintaining a very high quality and preventing rot formation, which is of great importance is. In particular, algae are produced in sun-favored locations, so it is the trend of sustainability and environmental awareness to use the available solar energy as a primary source of energy for the drying of biomass and microorganisms. Especially the production of preferably microalgae as a green biotechnology is a pioneer in ecological industrial applications and a sustainable use of resources is sought.
    According to a particular feature of the invention, the distribution of the concentrated biomass, in particular the concentrated algae or microorganism suspension on the drying belt and / or the heating of the biomass on the drying belt and / or the separation of the biomass from the drying belt is carried out continuously. The previously switched
    The production process as well as the harvesting process and the concentration of the biomass are predominantly continuous. Thus, the continuous drying of a run-up of large amounts of biomass is avoided and avoided an undesirable oxidation process and spoilage of the biomass as far as possible.
    According to a particular embodiment of the invention, the conveyor belt with the biomass adhering to the conveyor belt is guided according to the position of the sun to heat the air for drying the biomass. The tracking of the position of the sun increases the effectiveness and allows a largely extensive use of the available energy without having to resort to larger collectors, for example.
    According to another particular embodiment of the invention, the drying of the biomass is carried out at 40 to 50 ° C. The targeted temperature bandwidth is limited to a maximum desired temperature for maximum efficiency to preclude thermal degeneration of the biomass.
    According to a further special feature of the invention, the air surrounding the drying belt is heated to dry the biomass directly via the solar radiation and optionally indirectly via, provided in the closed system, reflection surfaces. In addition to the direct solar radiation on the side facing the sun, the efficiency of the system is increased by the fact that on the side facing away from the sun by reflectors an energy input into the biomass is achieved.
    According to a particular embodiment of the invention, the biomass to be dried on, in particular arranged at an angle, drying belt is first conveyed from bottom to top and exposed to direct sunlight and conveyed after deflection of the conveyor belt to be dried biomass on the drying belt from top to bottom and the indirect Exposed to sunlight. The angle of the direct as well as the indirect irradiation is adapted to the sun's position to optimize the energy input
    According to a particular embodiment of the invention, the moisture and / or the temperature of the air and / or the biomass is measured both when distributing the biomass on the conveyor belt and / or in the drying section and / or in the region of the collecting container. The measurement of moisture and temperature of both biomass and air are used for process monitoring and quality assurance as well as the supply of data for process control and process optimization.
    A further object of the invention is to provide a device with which the economic implementation of the above method is ensured.
    This object of the invention is achieved by a device for carrying out the method for obtaining dehumidified biomass.
    The device according to the invention is characterized in that a conveyor belt, in particular an endless conveyor belt, is provided for receiving the biomass, that this conveyor belt is surrounded by a translucent envelope, for example a tube or a channel-like envelope structure, to form a closed system that the conveyor belt is arranged with the wrapping in a freely selectable angle to the horizontal and that this conveyor belt with the envelope rotatable, preferably on a turnstile, is arranged. The serious advantage is the fact that the leadership of Trabsportbandes takes place in a translucent shell structure, this shell structure is mainly used to protect the biomass from negative external influences and contaminants.
    According to a particular feature of the invention, the conveyor belt with the envelope with a reflection surface, preferably a mirror, in particular a flat or parabolic mirror, underlaid. The advantage is obvious. A reflection surface, as seen from the direction of the sun's rays behind the translucent envelope structure, supplies the side facing away from the sun with energy
    According to a particular embodiment of the invention, the translucent envelope made of plastic or glass. Both materials have their special advantages and can be used for specific applications.
    According to a further special feature of the invention, the conveyor belt is an adhesive tape. Adhesion or attachment force establishes an interfacial layer that forms between the belt and the concentrated suspension with biomass. The main feature of adhesion is a mechanical cohesive phase involved. Such a band has proven to be very suitable for the purpose of transporting the biomass in the experiments.
    According to a further embodiment of the invention, an air heater is provided for heating the air for drying the biomass in the absence of sunlight.
    It is obvious that an air heater can optimize the process.
