Definitions

  • the present invention relates to a device that makes it possible to remove the main stem in the green leaves of plants with stemmed leaves such as tobacco and the like during harvest and to use the lamina parts of the leaves more efficiently in the industry.
  • Tobacco is a plant that is cultivated annually in the world. Two months after cultivation, the harvest of mature leaves begins. Harvesting is the process of plucking the main stems (Leaf) of the plant after the maturation of the leaves from the place where they are connected to the plant body. The harvesting process is carried out on the stem in four or five steps, at intervals from bottom to top. All harvested green leaves are exposed to curing process without waiting.
  • tobacco curing is performed in 4 different methods in the state of the art. These can be listed as follows; flue-cured curing, air curing, fire curing and sun cured.
  • the tobaccos that have been harvested with their main stems are connected to the apparatus called racks and arranged on the oven shelves during harvesting.
  • tobaccos are dried by passing the hot air supplied by using fuels such as natural gas, fuel-oil, etc. through them by means of circulating in the oven for 6-7 days.
  • the tobacco hung on the sticks in closed depots is dried by the heat obtained from the fires made in the depot.
  • the harvested green tobacco leaves are arranged one by one on a rope or similar materials in a manner such that they do not fall on the ground. Subsequently, it is placed in sun-drenched places and dried naturally. In all these methods, the harvested green tobacco is hung on ropes or racks before curing.
  • This sorting process is a process that requires considerable attention and labor and at the same time takes time. It definitely requires a large number of workers to be employed. For this reason, it causes tobacco production costs to increase. The most important cost item in cost calculations made for tobacco is the tobacco sorting.
  • tobacco leaves are respectively subject to the following processes respectively; de-greening and color determination, curing of the leaf lamina and curing of the main stem. Although the first two of these steps are completed within a short period of time, high energy and attention is required to dry the main stem.
  • the internal temperature of the oven should be specifically kept at a temperature about 70 O; oth erwise, the stems will decay and the leaves will become unusable.
  • TR2010/10413 a method for curing classical and semi-oriental tobaccos by artificial heating method is disclosed.
  • tobaccos are exposed to the steps of withering and yellowing, color fixing & lamina curing, stem curing, cooling and annealing.
  • the curing process is performed with the heat obtained by using electricity, solar energy, natural gas, LPG and any other energy sources.
  • EP3338566B1 in the state of the art, a method for curing tobacco leaves by curing is disclosed. Two depots and two different heat sources are used in the method. The method is initiated by flowing the first combustion gas through a first flue pipe of tobacco leaves placed in the first depot so as to heat the air in the first depot. Hereby, subsequently the cured tobacco leaves are taken into a second depot where they are exposed to re-curing process with a second heat source supplied from a second flue pipe.
  • the stem and the lamina parts of the leaf cannot be used together in cigarette factories, the stem and the lamina must be separated from each other before cigarette production. First of all, the leaves of the tobacco after the curing process are cut; then, the lamina parts and stems are exposed to separation process. This process causes extra labor, high energy use and large amount of waste losses. Furthermore, the shrinkage of the parts of the lamina to be used in cigarettes reduces the efficiency; it leads to the shorter lengths of the shredded tobacco. As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.
  • the present invention is related to a device suitable for use in the harvest and sorting out of tobacco leaves which fulfills the abovementioned requirements, eliminates all disadvantages and brings some additional advantages.
  • the main aim of the invention is to develop a device suitable for use on leaves with stemed structure particularly on green tobacco leaves that provides the separation of the leaf lamina from the main stem part during harvesting.
  • Another aim of the invention is to provide a device that both provides the tobacco leaf to be harvested and extracted from its main stem simultaneously.
  • Another aim of the invention is to provide a device that saves labor, energy and time by eliminating the need for the main stem curing phase, which is a part of the curing process of tobacco in the state of the art.
  • Another purpose of the invention is to provide a device that shortens the total curing time of green tobacco leaves by separating the main stems before curing and therefore improves the quality of tobacco.
  • Another aim of the invention is to provide a device that allows to perform the decomposition of tobacco leaves after curing with less energy consumption compared to the state of the art by means of separating the main stems before curing.
  • Another aim of the invention is to provide a device that increases the preference of natural methods such as sun curing method that does not require labor and energy instead of curing methods that reduce the quality of tobacco leaves such as fire curing method.
  • the present invention is a leaf sorting out device suitable for use on all leaves with stemed structure, including green tobacco leaves, simultaneously providing the harvesting of the leaf and the separation of the leaf lamina from the main stemed part, it comprises the following;
  • At least one drum mechanism positioned on the body panel that provides linear movement by holding the leaf from its main stem and compressing the same
  • At least one harvesting knife that allows the main stem to be harvested by cutting from the section where it connects to the leaf stalk
  • Figure - 1 is a perspective front view of the inventive device.
  • Figure - 2 is a perspective enlarged view of the inventive device.
  • Figure - 3 is a perspective rear semi exploded view of the inventive device.
  • the present invention is a leaf sorting out device (1) suitable for use on all leaves with stemed structure, including green tobacco leaves, simultaneously providing the harvesting of the leaf and the separation of the leaf lamina from the main stemed part, it comprises the following;
  • drum adjustment element (4) that enables the drum mechanism (3) to be adjusted at the desired opening
  • compression mechanism (5) that provides the pressing force required by the drum mechanism (3) to compress the leaf stem
  • At least one harvesting knife (8) that allows the main stem to be harvested by cutting from the section where it connects to the leaf stalk
  • the body panel (2) is in the form of a panel that has a drive center (9) on one surface and moving parts on the other surface.
  • the inventive device (1 ) also comprises at least one cover (13) that integrates with the body panel (2) and houses the drive center (9) ( Figure 3).
  • the drum mechanism (3) comprises two drums that are parallel to each other and enable the leaf to move forward by compressing the same between them.
  • Said drum mechanism (3) is designed to compress the leaf by holding it from its main stem. Since the main stem thickness of each leaf will be different from each other, the gap between the drums should be adjusted accordingly.
  • the drum adjustment element (4) provides the adjustment of the distance between the drums according to the leaf stem thickness. Said adjustment can be performed manually or automatically with a sensor that measures the stem thickness of the leaf.
  • said compression mechanism (5) has
