Definitions
- the storage chamber is itself divided into two parts by a partition wall, namely a part with a bottom diffusing metal, intended to receive the cryogenic mass for the preservation of frozen products, and a portion with an insulating bottom, charged with cryogenic mass for preserving fresh produce.
- a partition wall namely a part with a bottom diffusing metal, intended to receive the cryogenic mass for the preservation of frozen products, and a portion with an insulating bottom, charged with cryogenic mass for preserving fresh produce.
- Each of these parts of the room cryogenic system comprises, in the front wall, connection means with a external source of carbon dioxide.
- the process continuous supply by triggering the supply of the solenoid valve arranged on the injection cannula. In the event of a fall in the vacuum during fluid injection, the Feeding process is interrupted.
- the suction group is started as soon as the positioning sensors and the vacuum sensors indicate, at the housing of command and control, that everything is in order so that the prior aspiration into the refrigerant compartment is prior to fluid injection and creates a slight depression promoting relaxation of the cryogenic fluid.
- This depression attracts, in the suction box, the carbon dioxide resulting from the relaxation of carbon dioxide in the liquid phase and therefore prevents any diffusion of this gas into the atmosphere and close of the operator.
- the drawer 3 comprises, or is juxtaposed to an opening 8 which is formed between it and the upper wall of the container 2, and which is intended to pass the carbon dioxide gas phase, not converted into snow when injecting carbon dioxide into the cooler compartment.
- the housing 26 command feeding the suction cups 15a to 15c. Under the effect of the depression that runs through them, these suckers come to press against the front wall with a force that is sufficient to retain the housing, even when it is subjected to a force of reaction opposing the injection pressure which is of the order of 15 to 21 bar.
- the plating of the suction cups is checked, on the one hand, by the device 24 for measuring the vacuum in the vacuum circuit, and secondly, by the contact of the second sensor 16. If both sensors do not emit a contact signal, and / or if the vacuum circuit is subject to insufficient vacuum, the control and control cabinet 26 interrupts the feeding procedure, in order to force the operator to check the reasons justifying these defects.
- the sensors 16, the measuring device of the depression 24, or the suction operation sensor react on the cabinet 26, it controls the closure of the solenoid valve in use and puts safe installation.
- the detector 36 reacts on the control and control cabinet 26, so that it does not does not control the supply of the solenoid valve 17a, 17b in service, if the failure at the beginning of the cycle or stops feeding, if the failure occurs in cycle course.
- the suction mouth 14 of the box 13 is bordered by a sealing lip 40, elastically deformable, such as flexible elastomer, for example silicone. Thanks to its elasticity, this lip comes into perfect contact with the front wall of compartment B, whatever the parallelism of this wall, its surface appearance or the coincidence of the mouth 8 with that 14.
- the device supply includes an additional solenoid valve 42 disposed on the circuit supply 20 from the cryogenic fluid reservoir 22 to the housing 10.
- This solenoid valve is arranged downstream of the manual valve of safety 43, compulsorily arranged at the outlet of the tank. It is connected by a electrical circuit 44 to the control and control cabinet 26.
- This solenoid valve 42 is brought into the closed position, as soon as the feeding device passes into emergency stop, at the request of one of the sensors or detectors, or at the request of the operator.
- the device is equipped with a button 45a emergency stop arranged on the front face of the housing with a button 46 of cycle start, and another emergency stop button 45b disposed on the housing 26.
- the operator no longer to go actuate the manual valve 43 at the outlet of the tank, and sometimes located at more 100 meters from the place of loading of the containers.
- the housing 10 is disposed below of the box 13 and with a space E which, on the one hand, thermally isolates the box 10 frost forming in the box by the gas at - 40 ° C, and secondly, facilitates the interchangeability of the casing by reducing the time required for its replacement.
- Figure 2 shows that connectors 19 and 29 with cryogenic and electrical fluid, are arranged in an area of the housing all the more easy to access at this location, the box 13 has sections.
- the structure 12 provides a good grip and provides reliable mechanical protection of connectors, buttons, cannulas and suction cups, against possible shocks with containers being handled.
- connection means of this tray 50 with the distribution box 110 are constituted by two hydraulic couplers 52a, 52b, of male type and equipped with shut-off valves 53a, 53b.
- each of these flaps communicates directly with the interior of the tray 50, whether or not it includes one or more partitions or baffles.
- couplers are intended to cooperate with two female couplers 54a, 54b, protruding from the front face of the housing 110. These two couplers are also equipped with self closing shutters. As in the previous embodiment, the couplers 54a, 54b are juxtaposed with suction cups 115a, 115b, 115c and with contact sensors 116 and are connected to solenoid valves 117a and 117d fed, the first, by a filling line 55 and the second by a drain line 56.
- the different suction cups 115a, 115b, 115c are connected by an internal network 57 to 123 means generating vacuum, and for example, to a pump to vacuum or a venturi, this means being equipped with a measuring device 124 of the pressure in the circuit 57.
- the various electrical circuits of the solenoid valves, power sensors of the means 123 are connected to a connector 129, itself connected by a flexible link to a control and control cabinet 126.
- the filling line 55 is connected by a flexible connection 58 and to a pipe 60, to a tank 59 holding the coolant in refrigerant condition.
- the pipe 60 is equipped with a manual valve 143 and a connected solenoid valve 142 by a circuit 144 to the control and control cabinet 126.
- the conduit 60 is equipped with a pump 62 whose supply circuit is controlled by the cabinet 126.
- housing 110 is not associated with a suction box.
- the coupling of the housing 110 with the tank 50 of the refrigerant compartment B is performed with the security provided by the contacts 116, with the plating force provided by the suction cups 115a to 115c with control of the plating force by measuring device 124.
- All the emptying and filling functions are controlled by the control and control cabinet 126, so that the emptying starts slightly before filling and ends a few moments after him.
- the drain line 56 is equipped with a sensor of temperature 67 which is connected to the control and control cabinet 126 by a circuit 68 to trigger the stop filling and emptying when the fluid through the conduit 56 reaches a given temperature, close to the temperature of the fluid contained in the reservoir 59.
- the feeding device has many safeguards that allow a operator, trained or not, to use it safely to inject into the compartment refrigerant of a container, either liquid phase carbon dioxide or a fluid coolant.
- Security management in the control and control cabinet 26, 126 is provided, depending on the applications, by a PLC or a computer card programmable, with the management of a database for calculating times injection.
