Definitions

  • the invention as exposed on the wording of the present specification, relates to un process for dehydrating Moringa oleifera, imparting to the function it is intended to, several advantages and innovative characteristics, which will be described in detail below and which mean a remarkable improvement with regard to which is currently known for the same purpose.
  • the object of the invention focuses on a process for dehydrating or drying the leaves of Moringa oleifera which presents the peculiarity of being fully friendly to the plant's active principles, achieving a maximal preservation of its properties, since by reducing the time between cutting and packaging, and always keeping the temperature below 40°C, it avoids spoiling the enzymes and phytohormones which said plant contains.
  • the application field of the present invention is framed within the agricultural and alimentary sector, focusing particularly on the field of industry of dehydrated Moringa oleifera packaging and marketing.
  • Moringa oleifera is a tree originated in the North of India which posses innumerable properties, both nutritional and medicinal and from which, excepting the root, every parts are edible, i.e., leaves, fruits and flowers.
  • the objective of the present invention is, then, developing a new process for dehydrating this plant so as to being able to keep intact its enzymes and, therefore, all its properties, having to note that, at least on the applicant's part, it is unknown the existence of any other invention of similar application presenting technical characteristics similar to the ones presented by the procedure herein recommended.
  • said process comprises the following steps:
  • cut branches are carried to the cleaning and drying area in the ventilated boxes, where they are placed after being cut, and, when they arrive to said areas, the same boxes can be used or they can be relocated in trays or in shelves, also ventilated, where they stay separated and in different heights for said cleaning and drying.
  • the small bunches are cleaned with a quick wash in fresh drinkable water, so as to remove any impurity or dirt and to keep cool or low their temperature.
  • Said quick wash can be manual, small bunch by small bunch, or directly within the boxes, trays or shelves where the small bunches are placed.
  • the branches of Moringa oleifera are cut and put directly in metallic trays or in boxes of perforated and light plastic, of the type suitable for food and resistant to high temperatures, from which they move no more until being dehydrated, and with which are mounted pallets which are washed and introduced directly in the dehydration chamber.
  • the containers whether boxes or trays, as it was said, are ventilated, i.e., the have the base and, where applicable, the side walls in the form of a grille, being preferably of plastic material which withstands until 100°C without affecting its quality nor contaminating the Moringa.
  • the temperature never exceeds 40°C, which slows the dehydrating process of the branches. For said reason, and in order to accelerate the process, a lot of air is passed among the trays.
  • the dehydration chamber is a dark room, without natural external light (although it has artificial light for emergency cases), airtight, and which also has heaters, a dehumidifier and fans.
  • the dehydration process consist of making the Moringa exude the water it contains, and in order to avoid that it reabsorbs the water it is necessary to control the air circulation and its humidity in every moment.
  • the dehydration chamber is filled with the trolleys of trays or pallets of boxes so as to begin to make the Moringa exude, however, it makes that over time the air gets laden with humidity. Therefore, the room is heated below 40° and the air humidity is removed.
  • this humid air is expelled and it is changed or renewed by air dryer and cooler, being repeated this process some times.
  • this process of changing the air is performed by means of a programmed control device which automatically opens and closes the windows or ventilation grilles of the dehydration chamber when the level of humidity and/or temperature reaches the expected point.
  • the Moringa dried it is removed from the trays and the leaf is separated from the stem, manually or mechanically, having to note that said stem separation reaches a 99% thereof, which increases the concentration of the actives existing in the obtained leaves.
  • the leaves are cut for being used as an infusion or as a spice, or they are pulverized and vacuum-packed.
  • the dehydrated plant obtained can be marketed as an ingredient in sachets, powdered, as juices, sauce, encapsulated, within tablets, cookies and bars, etc.
  • This dehydration process allows for elaborating a concentrate which is made through a soaking and subsequent distillation at low temperatures, using a vacuum for lowering the vaporizing point, and using alcohol, water or glycerine or a combination of the named substances for the extraction of the required substances from the plant.
  • This elaboration process using dehydrated raw material according to the dehydration process object of the present invention, allows that all the substances present in the living plant, pass to said solution, and that after the evaporation of this liquid, the concentrate or the paste obtained presents the original nutrients previous to the dehydration of the plant, concentrated and intact.
  • FIG 1 an example of the dehydration chamber (1) is observed, in which the process for dehydrating Moringa oleifera according to the invention is performed, being appreciated on it how the small bunches (2) of branches of the plant are placed in ventilated containers (3) in the form of boxes or trays which are incorporated on supports (4), forming pallets or trolleys, of shelves (5) of several heights.
  • the containers (3) are boxes stacked in pallets.
  • means for forcing the circulation of air and through the shelves (5) among the containers (3) consist of, at least, a heater (7), for warming the air within the drying room, a dehumidifier (8) and one or more fans (9) so as to force the maximal recirculation of warm air as well as for renewing it every time the windows (10) or ventilation conducts are opened.
  • the ventilated containers (3) consist, of trays with grille-shaped base (3a), stackable in trolleys, such as the figures 2 and 4 show, said trays being able to be of fibreglass, stainless steel or plastic, or of boxes with grille-shaped base and partition walls and stackable in pallets, such as figures 1 and 3 show.
  • Figure 3 shows an example of the containers (3) in the form of ventilated boxes wherein, optionally, the small bunches (2) are carried from the plant to the dehydration chamber (1), being appreciated how said boxes, which preferably are made of plastic, present also the base and the side walls in the form of a grille.
  • the process comprises the following steps:
  • the ventilated containers (3) are ventilated trays or boxes which are incorporated on supports (4) forming the shelves (5) of several heights, and preferably, the cut branches are placed in ventilated boxes for being carried directly therein to the dehydration chamber.
  • the cut branches are placed firstly in ventilated boxes, wherein they are carried to the dehydration chamber and then, in said chamber, trays which are incorporated on supports (4) forming the shelves (5) are relocated.
  • the renewal of the humid air by new and dry air is performed automatically by means of a programmed control device which automatically opens and closes one or more windows (10) or other ventilation conducts, which will be performed as a function of the pre-programmed parameters in said device and of the readings of humidity and temperature sensors provided to this end in the dehydration chamber.
  • the essential steps of the procedure were: cutting the branches of Moringa oleifera, and, within 1 hour, placing them in a dehydration chamber (1) where heated air is passed among them, the temperature never exceeding 40°C, and renewing periodically the air with the humidity which the plants have exuded by new and dry air.
  • FIG 5 an example of dehydration chamber with the load complete and properly arranged is shown, having represented on it, by means of arrows, the mode in which the air circulates therein for a correct drying of the plants, meanwhile in figure 6 , the dehydration chamber with a single row of shelves is represented, and by means of arrows, it is observed how the route of the air in such case is not suitable.
