Definitions
- the invention relates to the field of transporting cold products in pipes, in particular in the food sector.
- various industries in particular the food industry which will be taken as a preferred but not exclusive example in the following description, there is a need to transport frozen products in pipes to deliver them to a processing or storage site (including sites where packing or packaging is carried out).
- These frozen products can be in a viscous form or in a divided solid form.
- soups As a viscous product, there may be mentioned soups. As products in divided solid form there may be mentioned peas and other vegetables.
- the object of the invention is to propose a satisfactory solution, both from the technical point of view and from the economic point of view, to the problem of the heating of frozen products during transitional periods, as just explained.
- the subject of the invention is a method of using a facility for delivering a frozen product comprising a delivery pipe connected at its upstream end to a storage container or to a facility for producing said frozen product. , characterized in that, prior to the introduction of said product into said pipe or during an interruption of the operation of said delivery installation, a cold fluid is passed through all or part of said pipe so as to bring said pipe to a temperature compatible with maintaining said product in frozen form during its stay in said pipe, or maintaining said pipe at said temperature. Said cold fluid can also be made to circulate around said pipe.
- Said cold fluid is, for example, refrigerated compressed air.
- the subject of the invention is also an installation for delivering a frozen product of the type comprising a storage container or an installation for producing said frozen product and a delivery pipe which is connected to it at its upstream end, characterized in that it includes means for passing a cold fluid through said pipe from at least one point on the pipe (preferably located near one of its ends in order to make it a co-current or counter-sweep current of the flow direction of the product in the pipeline.
- Said pipe can be equipped with a double envelope, and it comprises means for circulating said cold fluid or another cold fluid also inside said double envelope.
- the invention consists in bringing or maintaining the pipeline at a temperature compatible with the maintenance of the product in frozen form. Before starting or resuming the operation of the transport installation thanks to a circulation of a cold liquid or gaseous fluid inside the pipeline itself. The invention will be better understood on reading the description which follows, given with reference to the single appended figure which schematically shows an example of an installation for transporting a cold product according to the invention.
- the example of installation according to the invention of the single figure comprises, in known manner, a refrigerating container 1 where a product, for example food, is stored in frozen form.
- a product for example food
- This product can be in the viscous state, or be in a divided solid form. It must be able to be extracted from the refrigerating container 1 by means such as a pump 2 placed on the path of a pipe 3 connected by its upstream end to the refrigerating container 1.
- the downstream end 4 of the pipe 3 opens onto the medium. outside to deliver the product, for example on a packaging line or in any other installation ensuring product treatment.
- the product can also, of course, be delivered directly to the end user.
- the installation comprises devices making it possible to pass a cold fluid through the pipe 3 itself when the installation is started or restarted.
- this fluid consists of compressed air cooled beforehand with liquid nitrogen.
- This compressed air passes through a pipe 5 opening into the pipeline 3 for transferring the product at a point 6 located as close as possible to its upstream end, therefore from the outlet of the refrigerating container 1.
- various devices conventional in the treatment and cooling of compressed air There are for example filters 7 ridding the compressed air of its chemical and microbial pollutants, a dryer 8 ridding it of its water vapor, and a refrigerant 9.
- the compressed air initially at a ambient temperature, is cooled to a temperature of the order of the temperature at which the product to be transported in line 3 must be delivered.
- this cooling is carried out by heat exchanges with nitrogen which penetrates in liquid form into the refrigerant 9 via a pipe 10 coming from a cryogenic installation (not shown), and leaves it in gaseous form by a pipe 11.
- Circulating this refrigerated air in line 3 before the start of the introduction of the frozen product to be transferred has many advantages compared to previous practices of ensuring the cooling of line 3 by the product itself or a fluid circulating in a double envelope:
- the refrigerating container 1 can be either a simple storage container for the frozen product to be delivered, or for example an installation for manufacturing this product.
- refrigerated compressed air is only a preferred example, and other fluids such as nitrogen or CO 2 could be used similarly and always by way of illustration, in refrigerated liquid or gaseous form.
