Problems solved by technology

[0007] Another problem faced on board cruise ships is the huge amount of waste paper or cardboard that is generated and cannot be discharged for disposal in the harbor as they may contain microorganisms that are harmful to the local flora
Therefore, currently the paper or cardboard is incinerated on board, for which purpose special expensive equipment is required

Embodiment Construction

[0057] With reference to the accompanying drawings, a device for carrying out the method according to the invention comprises a turbocooker T comprising a cylindrical tubular body 1 with a heatable inner wall 2, closed at both ends by end plates 3, 4, set There is a feed opening 5 and a discharge opening 6, and inside there is a rotatably supported coaxial vane rotor 7 whose vanes 8 are arranged helically. The cylindrical tubular body 1 is externally coaxially provided with heating means 9, shown in schematic form, comprising a resistor or RF source disposed on the outer surface of the cylindrical tubular body 1 or coaxially on the outer jacket, heating A fluid is passed therethrough, the heating fluid preferably consisting of water vapor or a thermally transparent oil suitable for flow.

[0058] Said equipment also comprises a turbo dryer T' comprising a cylindrical tubular body 101 with a heatable inner wall 102, closed at both ends by end plates 103, 104, provided with an i...

Abstract

The invention discloses a treatment method for food waste or organic waste which is composed of the food waste and cellulosic waste. According to the treatment method, the food waste is ground, boiled, disinfected and dried, and turbine cooking ware (T) is arranged for carrying out boiling and disinfection. The boiling and disinfection include the following steps that food waste continuous flow from the grinding step is conveyed into the turbine cooking ware (T), and a blade rotor (7) rotates at the speed of being higher than or equal to 150rpm inside the turbine cooking ware (T); the continuous flow makes centrifugal movement towards an inner wall (2) of the turbine cooking ware, so that a highly turbulent flow, dynamic, thin and tubular fluid layer is formed; ground food waste particles can be driven by blades (8) to move forwards and make contact with the inner wall of the turbine cooking ware, and the particles are heated to the temperature of at least 90 DEG C and move to a discharging outlet (6); and the disinfected and ground food waste continuous flow and water vapor continuous flow are discharged out of the discharging outlet.

Description

technical field [0001] The present invention relates to a method for treating food waste or organic waste. [0002] In particular, the present invention relates to the disposal of food waste produced by catering services provided on board ships, especially pleasure boats, or organic waste making such food waste and cellulosic waste, especially paper or cardboard waste. Background technique [0003] The latest generation of cruise ships is capable of transporting more than 3,000 passengers, so the on-board catering services of these ships have to serve tens of thousands of meals a day. A large portion of the daily food supply is not actually or completely consumed and, therefore, a large amount of food waste is generated which must be disposed of. [0004] The problem is not limited to pleasure boats alone, but also ships that transport large numbers of people, such as military ships. [0005] According to current international regulations (MARPOL Annex V), food waste can b...
