Definitions
- the present invention relates to a continuous system of heat treatment of divided solids coupled to a solid-gas reaction whose main application decontamination of divided solids, including food products, such as herbs, spices, powders etc.
- the cost of obtaining quality is a current brake that the regulations of the European community are in the process of remedying by obliging more and more important guarantees.
- the targets are: Escherichia Coli enterobacteria, total flora, yeasts and molds.
- autoclave-type batch systems batches are processed individually, which allows perfect traceability but is constrained to high labor costs. These systems are widely used in the pharmaceutical industry.
- the mode of transport of the divided solids and the mode of treatment and heating greatly influence the cost of the installation, the quality of the treatment and the quality of the final product.
- a continuous decontamination unit is composed of a product feed, a debacterization unit, a cooling drying unit and a conditioning unit.
- the product's power system is often an option that users sometimes choose.
- the steam debacterization part obviously requires steam.
- a boiler to produce this steam is an option that few users choose, in fact food manufacturers are usually equipped with steam in their factories. However, you must be very careful that a unit requires regulated steam and often overheated between 100 and 140 ° C. This involves an option with a superheater. It is also necessary to provide the steam extraction part to the outside. It will usually also be used for extraction for cold and dry air used in the cooling part, which reduces condensation problems.
- the product is then brought into the drying-cooling unit.
- the cost depends largely on the demand of the user: what temperature of product compared to the external temperature can it accept at the exit of cooling, knowing that the last 5 ° C are the most difficult to obtain and that the deviation compared at ambient conditions is often important (in Malaysia it is 30 ° C and 95% humidity, in Greece 35 ° C and very dry, the requirements are different).
- the main systems known on the market are to create: a fluidized bed (transport by vibrations) moving the particles on a metal plate pierced with a multitude of holes and the steam serves to heat the particles and to debacterize them.
- the transport system must not be done by a screw because it does not guarantee homogeneity of treatment.
- the heating of the fluidized bed will be done by commercial electric resistances.
- the system must make it possible to treat all the granulometries including the powders.
- Figure 1 shows schematically and in perspective a continuous decontamination system incorporating a debacterization unit 1 according to the invention
- FIG. 5 shows in perspective the sole view from below according to Figure 4, but showing an integrated heating circuit.
- the decontamination system generally designated in FIG. 1, comprises in a known manner:
- a debacterization unit 3 consisting of a fluidized bed moving the particles by vibration, associated with a supply of steam or other gas;
- the debacerisation unit 3 comprises a stepped hearth 5 adapted to allow the product 6 to be transported successively in a first transport phase H generally horizontal, vibro-fluidized, and at least one second vertical transport phase V, these phases H, V in steps being obtained, from a step 7 globally horizontal and solid, forming the sole 5 providing the first phase H, while a riser 8 vertical, provides the second phase V, said riser 8 or the nose 9 7 having a ramp 10 for injecting superheated steam or other gas, acting in decontamination on the product 6 during its transition from horizontal phase H to the vertical phase V and to the next horizontal phase H.
- the solid-gas reaction is initiated in the first vertical phase on the already heated product. This vertical phase ensures homogeneity of treatment on 100% of the particles.
- the reaction continues with the next horizontal phase since the vibro-fluidized bed continues to react with the gas phase.
- the process is continuous and lasts the entire length of the debacterization unit.
- the gas used will be water vapor (generally superheated).
- the sole 5 staircase comprises at least two steps 7 and a counter 8 step, but of course this is not limited and may vary depending on the nature and amount of product 6 to be treated, it is thus only as embodiment of the sole shown in the figures comprise three steps 7 and two risers 8.
- the hearth 5 has, under the underside of its full steps 7, electrical resistances 11, able to heat beforehand by contact, the product 6 before the passage in front of the ramp. injection 10 of steam or other gas, the riser 8 or the walking nose 9. This heating prerequisite avoids the risk of condensation of steam (or other gas) and limits the amount of steam (or other gas) to use.
- the steps 7 of the floor 5 staircase can be inclined up to plus or minus 30 ° from 1 'horizontal.
- the vibrations of the sole 5 are obtained by means of an electromagnetic vibrating motor 12, an unbalance motor, or an unbalance box according to the products.
- the system according to the invention makes it possible to heat-treat divided solids, that is to say, to treat particles from two microns to several centimeters. It makes it possible to react divided solids with a gas. This is a major advantage which is the guarantee of a very great versatility highly sought after by users who process several products, of different sizes, densities ...
- the simplicity of the system also provides the advantage of making its maintenance easy and fast, excluding any use of consumables.
- the size of the installation is to be adjusted according to the requested capacity for the width and the passage time for the length, but a length of 6 to 8 m seems already to be required for a passage time of 3 minutes and 30 seconds which is a standard in the profession.
