CA2296848A1 - Process for filtering agri-food materials that are packed in bags - Google Patents

Abstract

A bag used to package solid food materials generally consists of waxed or aluminized paper and sealed so as to form a single compartment used to store these said materials. Its packaging is also designed so that these so-called materials are damaged as little as possible during transport. In the present method, the bag to be packaged is provided with at least one other compartment serving to accumulate part of the packaged material. We therefore divided the bag to be packed into at least two compartments. These compartments are separated by filters or colanders perforated so as to allow the desired materials to pass into the desired compartment without them coming out. These filters or colanders can be cut directly from the bag to be packed, that is to say from the paper or plastic forming the bag during the packaging process, or else added by gluing in a subsequent step forming part of the process of 'packaging.

Description

DESCRIPTIVE MEMORY
1. The present invention consists of a method of filtering the material solid food industry in bag packing.

2. It is common and generally recognized that agro-food to be packaged, are packed in bags made of plastics, waxed paper or aluminized. Once packed, these food products are transported and subjected to shocks, shuffles and vibrations. Part of the solid agro-food material inside containers is then broken, crushed, fragmented into smaller particles accumulating at the bottom of these so-called containers. These particle deposits, these “sack bottoms” for example, are particularly unpleasant and unpleasant for the consumer who ends up with these so-called deposits when he pays the last cereals of a box in his bowl for breakfast ... What the consumer wants to find in his breakfast, it is the grain and not the deposits collected in the packing bag. The compartment packaging are ineffective to solve this problem because it is actually this type that contributes to keep these so-called deposits, the agro-food material crushed during transportation residing with rest of the agro-food material still intact.

3. The creative idea that this new process implies is that (a "filtration agro-food materials solids inside the bag packaging ”allows to separate the particles smaller, like the deposits of particles still intact. The disadvantage of deposits in packaging can therefore be deleted.

4. A filtration process inside the bags creates a passage for deposits to another compartment. These filters must be arranged so that they can accumulate deposits or residues in the desired compartment without them coming out. Filters must be constituted so as to respect a chosen angle inside the compartment or compartments which must accumulate these same deposits or residues, so that these remain inside this same compartment. The perforations or notches serving as a door for deposits or residues towards the compartments which cumulate must have a certain dimension and must be arranged on a certain surface so that these same residues or deposits do not escape from the compartments which have them accumulated. The different steps of this process are described below I - Cutting filters (A) or folding (B) II- Perforation or design of the passages forming the filters III- Sloping fixing - insertion by gluing (A) or folding ((B) if formed from the container or packaging) filters.
IV- Packaging of food products to be used.
V- Closure of containers or bags.

5. POSSIBLE ACHIEVEMENTS
A bag packaging comprising a filter capable of isolating and retaining at least some of the material packed.
A bag packaging preventing part of the packaged material from borrowing the same exit path than the rest of the material when in use.
Filtration of the residues of the material packaged in said packaging.
A tank accumulating the residues of the material packed in the said packaging.
Isolation of part of the packaged material from the rest of the packed material.
The fields of application is in the food industry for agri-food materials packed in bag. To cite only a part of these, there are among others, the field of packaging cereals, there is also the packaging of potato chips, cookies, bulk materials, etc.

Claims (10)

1.A process to filter the food industry material inside bag packaging, including construction of a plastic, paper or aluminum filter allowing to isolate a party from the solid agro-food material packed in a bag. By inserting or forming filters inside the bags pack the food-processing material, we create compartments capable of retain agro-material desired food without it coming out. 2. A method, as defined in claim 1, wherein the filter is attached or formed from the bag during the stages of packaging of the agro-food material. 3. A method, as defined in claim 2, wherein the filters the inside of the bags to be packed are placed so as to constitute at least one side of at least one other compartment. 4. A method as defined in claim 3, wherein the part desired agro-material food is isolated in at least one other compartment, following its passage through said filters. 5. Any method, as defined in claim 4, employing a filter element or separating the solid food material inside the food packaging bags food. 6.Any method, as defined in claim 5, using a plastic filter, paper mill or aluminum inserted or formed from the food packaging bags allowing to filter or separate the solid food material desired inside the bag packaging. 7.Any process, as defined in claim 6, using the cutting or punching of a component of the packaging so as to allow material to pass bagged in at least another compartment to separate or isolate at least one agro-material food of agro-materials packaged food. 8.Any process, as described in claim 7, isolating the desired material, residues or deposits of the rest of the packaged food material. 9.Any process as described in claim 8, using at least one compartment accumulating the desired material, residues or deposits of agro-materials packaged food. 10. Any method as described in claim 9, using in whole or in part at the stages previously listed to arrive at filtering the desired material to inside a bag package can imports the material involved in the same process.
