Definitions

  • TITLE METHOD FOR PROCESSING KITCHEN WASTE
  • the present invention generally relates to the management and processing or disposal of kitchen or food waste and in particular relates to such management performed on a larger scale, for example in commercial and institutional kitchens and restaurants.
  • the main trend within refuse management in general is towards an increased sorting of waste at source. It is desirable to sort out material from commercial and institutional kitchens and restaurants, for biological treatment. Such material may with advantage be treated in existing biogas plants.
  • An object of such a development is to enable the production of a renewable vehicle fuel and at the same time to utilize the residue from the digestion process as a soil conditioner in farmland. This means that the ecocycle can come full circle.
  • the development is desirable to such a high degree that the government in some cases supports it through financial contributions partly covering the costs of the projects.
  • Equipment for managing and processing waste from restaurants and commercial or institutional kitchens has in certain cases also been designed in a corresponding way, discharging shredded or ground waste directly into the sewerage.
  • waste from restaurants and commercial or institutional kitchens has been brought to an infeed hopper directly connected to a grinder or shredder, from which the ground or shredded waste in turn has been conducted to a storage container in the immediate vicinity of the infeed point.
  • the shredded waste is stored in the storage container for one or several weeks.
  • the waste in the storage container can be treated mechanically by means of a screw, pump or other equipment capable of circulating the stored material.
  • the invention eliminates the above drawbacks in an efficient and appropriate way.
  • a general object of the invention is to provide a non-expensive and practically feasible solution to the problems associated with processing kitchen waste and the like.
  • a basic object of the invention is to find a simple and appropriate way of managing waste.
  • this object is achieved by connecting the outlet section of a waste disposer or the like to a storage container, to which the disintegrated waste or refuse is transported by means of vacuum.
  • waste stored in the container is periodically removed by means of vacuum, for example by being connected to a vacuum system.
  • waste can be removed to a center where it can be processed and transported away in a rational way.
  • Another object of the invention is to provide a simple and appropriate system for managing and processing kitchen waste.
  • a system is suggested for the efficient and environment-friendly processing of kitchen waste.
  • this system consists of a waste disposer positioned adjacent to the point where the waste is produced. Said waste disposer is connected to a storage container and is functionally connected to a suction or vacuum unit.
  • the storage container of the waste management system has a non-return valve provided in the outlet from a separator arranged in the vicinity of the storage container.
  • Fig. 1 is a partly schematic illustration of the waste management system according to the invention and the main components thereof;
  • Fig. 2A -B are side perspective and side elevational views, respectively, of an insertion cabinet in the system of fig. 1, the insertion cabinet being shown with various parts thereof removed for clarifying purposes;
  • Fig. 3 A is a side perspective view of a separator with a non-return valve in the system of fig. l;
  • Fig. 3B is an illustration showing the separator of fig. 3 A in a partly disassembled condition.
  • FIG. 1 discloses a currently preferred embodiment of a waste management system where the kitchen waste management method proposed according to the invention can be employed in order to provide an efficient and environment-friendly processing of the waste.
  • fig. 1 shows equipment adapted for processing waste from e.g. commercial and institutional kitchens.
  • the equipment or system according to the invention comprises an inlet cabinet 2 having a waste disposer 3 mounted therein and a control unit 5 (see fig. 1).
  • the inlet cabinet 2 is intended for positioning in a kitchen, i.e. adjacent to the point where the waste is produced.
  • a ventilation line 15 is preferably drawn from the inlet cabinet 2 to prevent odors.
  • the system further comprises a storage or collection container 6 with the required peripheral equipment, which is normally placed in a space separate from the kitchen and connected to the disposer 3 through an electrically controlled cut-off valve 3A and a suction line 7. Vacuum is generated in the suction line 7 by means of a suction unit 8 that is controlled by a control unit (not shown). A filter 9 is arranged between the suction unit 8 and the storage container 6.
  • a discharge pipe 14 that is connected to a discharge line 13 having a connector means 12 for connection to an emptying vehicle,.
  • the emptying vehicle is not shown in the drawings but is equipped with a vacuum unit and is preferably of a conventional type used for mobile vacuum waste management.
  • a ventilation line 11 leads also from the storage container 6.
  • the ventilation line 11 has an exhaust 11 A provided for instance on the roof of the building 10 in question.
  • An insertion unit 2 for food waste is located at a specific place.
  • the insertion unit is designed as a work cabinet having a lid 2A, a utility surface 2B and an insertion opening 2C (see fig. 2B) of e.g. 180mm.
  • the insertion unit 2 is connected to the waste disposer 3 through an insertion hopper 2D and the waste disposer 3 is in turn connected to a mixing container 4 via the cut-off valve 3 A.
  • the mixing container 4 is connected to the storage container 6 that is positioned at another location and that is provided with a separator 6 A, as well as to the associated vacuum source/suction unit 8.
  • the storage container 6 is connected to an outer wall (not shown) for emptying of the container by means of a vacuum truck or the like.
  • the connector means/cut-off valve 12 is arranged at the discharge end of the emptying pipe 13.
  • the storage container 6 and also the insertion cabinet 2 are ventilated through the separate ventilation pipes 11 and 15, respectively. The important functions are controlled by a relatively small PLC system, not shown.
  • the control unit 5 of the insertion cabinet 2 comprises a selector function 5A for selecting "Manual operation" or "Automatic operation".
  • the vacuum motor of the suction unit 8 is started, and then the cut-off/main valve 3A between the suction container 4 and the disposer 3 opens and water is injected through a line 2E into the insertion hopper 2D at pulsed time intervals.
  • the disposer 3 is started and runs for a predetermined period of time and grinds the waste stored in the insertion unit 2.
  • the ground or shredded waste is sucked by means of vacuum to the storage container 6 through the suction line 7.
  • an appropriate amount of transport air is automatically mixed into the mixing container 4 in a controlled manner. This transport air comes from the ventilation 15 and the controlled mixing of said air with waste from the disposer 3 enables a secure vacuum transport of the waste to the storage container 6.
  • the disposer stops When the predetermined time for the disposer 3 has passed, the disposer stops, the water is turned off, the main valve is shut off and the suction unit 8 is stopped. The procedure is repeated every time the lid 2A closes. Should the lid 2A be opened before the time for the disposer 3 has run out, the disposer stops and the cycle is terminated in a controlled sequence. The disposer cannot be started until the cycle is completely finished. Automatic operation
  • the unit In the position for automatic operation the unit is intended to cooperate with another machine, not shown, connected to the insertion hopper 2D through an enclosed intermediate piece, likewise not shown. The unit is then started through a service switch on the other machine. Otherwise, the function is identical to the one in manual operation.
  • the unit may also be provided with a specific insertion hopper designed in accordance with the CE security standard. In such a position, the unit runs continuously and can be fed uninterruptedly.
  • a control lamp 5B at the front or the control panel 5 of the insertion unit 2 indicates that the disposer 3 is in operation, and there is also an alarm lamp 5C for the indication of a possible interruption.
  • the solution proposed according to the invention provides a waste management system that well meets the specified object.
  • a very environment- friendly system is obtained since the entire management procedure is performed in a closed system from the in-feed into the insertion unit immediately adjacent the point where the waste is produced, to the emptying into the emptying vehicle.
  • the system is very hygienic both with regard to odors and to the actual waste that is removed without spillage in the closed system, such as directly to the emptying vehicle.
  • the described system works in a very efficient manner, due to its design with suction conveying directly from the insertion unit 2/disposer 3 to the storage container 6 as well as from the latter to the emptying vehicle.
  • the drawings illustrate an embodiment where the lower outlet 6B from the separator 6A opens into the storage container 6 and is provided with a non-return valve 16.
  • the non-return valve 16 consists of a shutter 17 of sheet metal that has a rubber plate 18 vulcanized onto its side facing the outlet 6B and that is pivotally suspended at the outlet 6B by means of hinges 19.
  • a non-return valve design has shown to work very satisfactory, since the pivotal sheet 17, or more specifically its rubber plate 18, sealingly engages the outlet when there is an vacuum in the pipe system 7 and the separator 6A, i.e. when the suction unit 8 operates.
  • the solution according to the invention is employed to process other waste or refuse than specifically kitchen waste.
  • kitchen waste is used to generally denote waste or refuse that contains organic fractions and that often contains a certain amount of liquid. Accordingly, the term is not to be considered as limiting the invention to be used solely in the direct vicinity of a kitchen.
