Description

Description of the invention

The subject of the invention is a disinfection device that can be used to disinfect food products such as fruit and vegetables in commercial establishments.

There are known methods of sterilizing food products that involve the use of hot steam, hot air drying and cooling. There are also known methods of sterilizing food products that involve the use of UV radiation and microwave energy. Sterilization processes are carried out in devices in the form of chambers, often using various types of conveyors.

A device for continuous sterilization of spices and other raw materials of plant origin is known from the Polish patent description PL 189396, comprising a trough-shaped reactor and, inside it and along its longitudinal axis, a twin-screw conveyor and a pipe with nozzles supplying steam, wherein one end of the reactor is mounted on a support attached to the base, while the opposite end of the reactor is supported by an actuator.

A device for sterilization of herbs, fruits and dried vegetables is known from the Polish patent description PL 223687, which consists of a screw conveyor based on a support structure, which has a heating jacket, to which a heating agent in the form of steam is supplied by a heating agent dosing system. A temperature sensor is mounted in the central part of the screw conveyor, while in the end part of the screw conveyor there is a transfer hopper, in which there is a product level sensor. Under the end part of the screw conveyor there is a hopper, which is connected to the body of the screw conveyor based on a support, which has a heating jacket and in the central part a transport shaft, which are heated by a heating agent dosed from the system. Along the longitudinal axis of the screw conveyor in its upper part there is a pipe with nozzles for injecting saturated steam, while in the upper part of the screw conveyor there is a vapour extraction collector. In the end part of the screw conveyor there is a hopper connected to the body of the screw conveyor supported on supports, which has a jacket for the cooling medium circulation, while in the lower part of the screw conveyor there is a blowing collector supplying dried air to the inside of the screw conveyor, and in the upper part of this screw conveyor there is an air extraction collector, and in the end part of the screw conveyor there is a discharge hopper. The device has a control system managing the parameters of the sterilization process of herbs, fruits and dried vegetables.

A disinfection device according to the invention is characterized in that a steam generator with outlet grilles is mounted on the base of the box housing, a bottom panel with fans is mounted above the steam generator, a middle panel with a mesh is mounted above the bottom panel with fans and a top sealing panel is mounted above the middle panel with a mesh, the bottom, middle and top panels having handles enabling assembly and disassembly of the bottom and middle panels in and inside the box housing, and of the top panel on the box housing, and furthermore the middle panel with a mesh is replaceable with an additional panel with UV lamps and handles, and in addition an exhaust duct with exhaust grilles and an outlet connector is mounted at the top of the side walls and rear wall of the box housing.

The subject of the invention in an example embodiment is shown in the drawing, in which Fig. 1 shows the disinfection device in an axonometric projection with the interior structure shown, Fig. 2 the top panel, Fig. 3 the additional panel with UV lamps, Fig. 4 the middle panel with a mesh and Fig. 5 the bottom panel with fans.

The disinfection device is built into a box-shaped housing (1) that has a base (2), a front wall (3), side walls (4) and a rear wall (5). A steam generator (6) with outlet grilles (7) is mounted on the base (2). A lower panel (8) with fans (9) is mounted above the steam generator (6), and a middle panel (10) with a mesh (11) is mounted above it. An exhaust duct (12) with exhaust grilles (13) and an outlet nozzle (14) is mounted at the top of the side walls (4) and rear wall (5). The top sealing panel (15) covers the box-shaped housing (1). The device also has an additional panel (17) with UV lamps (18). The bottom (8), middle (10), top (15) and additional (17) panels have handles (16) that allow their assembly and disassembly inside or on top of the box-shaped housing (1).

The disinfection device is used as follows. Fruits or vegetables to be disinfected are placed on the central panel (10) with a grid (11), the box housing (1) is covered with a top panel (15) and the steam generator (6) and fans (9) are started. The disinfecting steam generated in the generator (6) escapes through the outlet grilles (7) and is distributed by the fans (9) inside the box housing (1), while moving through the central panel (10) with a grid (11). After a specified time, the steam generator (6) is switched off, and the steam is discharged through the exhaust grilles (13), the exhaust channel (12) and the outlet connector (14) outside the device, while the fans (9) ventilate the interior of the box housing (1). For the needs of periodic sterilization of the interior of the box housing (1), the central panel (10) is replaced with an additional panel (17) with UV lamps (18), by means of which the sterilization process is carried out.
