Abstract

The present invention consists in a method for packing meat products, where an outer basket and an inner basket are used, this latter element having suitable characteristics to be located within the outer basket. The application of this method is intended to preserve the product during the normal conditions of manipulation in the transportation thereof, for example, from the supplier facilities to the distributer facilities, avoiding a sudden opening of the packing, which may generate condensation and degradation of the products or the contact with external agents and pollutants. In such a manner the invention facilitates the product to be subjected to freezing air currents in the surface zone and the bottom of a lower basket where it is stored. The aforementioned process is achieved by the presence of windows arranged in the perimeter bottom walls of the basket, which are aligned for allowing the freezing air streams to flow in a free manner. Said method allows the inner baskets to b e reused while these preserve the integrity of the packing, avoiding the generation of rubbish and disposal of materials with no added value for the packed product.

Description

PACKAGING METHOD FOR MEAT PRODUCTS j TECHNICAL FIELD OF THE INVENTION.

The present invention relates to a method of packing perishable products, specifically a packaging method for meat products arranged in bulk or in trays of a certain volume. j OBJECTIVE OF THE INVENTION.

The purpose of this invention is to dispose in perishable containers, perishable products, such as meat, which ensure the [í 'integrity of the envelope, avoiding the premature degradation of the product.

BACKGROUND. | Methods for packing meat products are known, such as for example I those where an external basket and an internal box are used, where the box I j internal is of low cost material, therefore of disposable and recyclable materials such as cardboard; in other words, the internal box consists of a cardboard box, in which the product is placed either in bulk or in smaller volume trays, so that a package is integrated that is entered into a cooling tunnel for freezing of the product, to later wrap it in a cover that protects it from undesired factors during its trampling and dispose it in an appropriate way to the final distributor.

TECHNICAL PROBLEM TO BE RESOLVED.

Although methods for the packaging of perishable products such as meat products are known, said methods expose the product to degradation conditions, because they are arranged in cardboard boxes to enter the freezing tunnel, with this, the cooling currents the tunnel does not reach the totality of the products inside the cardboard box, besides that it must be taken into account that the cardboard is an aijslarite material i thermal, so it requires more time for the cooling process, which does not mean that the total product has been processed uniformly. In addition to the above, cardboard boxes must be dispensable for the packaging company, so to reduce costs, a material of low cost and short useful life is available, which results in an expense that does not provide added value. to the product, having to be recycled since its structure would hardly be able to be reused. In addition to the above, the deterioration of the cash the cardboard box by said condensation.; i BRIEF DESCRIPTION OF THE INVENTION ! To solve the problem of ensuring a uniform cooling of packaged meat products, a process has been developed to favor the flow of cooling currents through the packages, thereby avoiding condensations that could degrade the product or the container carrying packages. , as well as the reuse of said containers with a management that procures their integrity during the packaging process. i The method consists of using an external basket and an inner basket, made of durable material such as plastic, with aligned openings for the flow of cooling streams in a cooling tunnel.

DETAILED DESCRIPTION OF THE INVENTION.

The method of packing meat products consists of having an external basket (10) and an internal basket (20). i The outer basket (10) is shown in Figures 1 and 2, is a friction-resistant plastic material with a suitable configuration to be moved) in a? i: belt conveyor (not shown), with a bottom wall (10a), perimeter walls (10b) and with an array of reinforcements (10c) on the walls; said basket and external (10) has a geometry that allows to stack a basket on another, Thus, both the perimeter walls (10b) and the bottom wall (10a) have a series of windows (10d) of a suitable geometry to allow the passage of the cooling currents and at the same time of sufficient dimension to provide resistance to the structure of the basket and allow the stacking of one over another in a certain number for palletizing.

The internal basket (20) is shown in Figures 3 and 4, is made of a friction-resistant plastic material such as plastic, with a bottom wall (20a), perimeter walls (20b) and with a reinforcement arrangement (20c) in the walls; said internal basket (20) has a in an external basket (10), stacked one on top of another, such perimetric (20b), form an inverted truncated pyramid, which slidably fits the internal faces of the walls (10b) of the outer basket (10). Similarly, both the bottom wall (20a) and the perimetric areas (20b) have a series of windows (20d), which align with the windows (10d) of the external basket (10), of a suitable geometry to allow the passage of cooling currents and sufficient to allow a structural resistance to said inner basket (20). ! i BEST WAY TO CARRY OUT THE INVENTION.

The method of packing meat products comprising the present invention is illustrated in Figures 11 A through Figure 11 E, which consists of placing an external basket (10) on a belt conveyor, which will lead it to a tunnel of cooling (not illustrated). Next, an internal basket (20) is placed inside the outer basket (10); this operation of the internal basket (20) with the belt conveyor, eliminating generate alterations in the external surface of the inner basket (20), where said alterations may damage the wrapper that is provided, so that any damage that may occur during the transfer in the belt conveyor, will be made to the basket external (10). Once this is done, the meat product is placed inside the inner basket (20), either in trays or in bulk, in the desired quantity as shown in Figures 5 and 6. It should be ensured that the quantity of product in the interior of the internal basket (20) does not exceed the capacity of the inner basket, that is, at a higher level than i indicates the maximum capacity of the inner basket (20); with the above, a package is integrated as shown in Figure 5, which is entered into the cooling tunnel, by means of the belt conveyor. ' I: Once the package is inside the cooling tunnel, submit the package to a series of streams (X) of cold air, which is at a temperature that generates the freezing of the product as shown in Figure 6 The windows (20d) in the inner basket (20) aligned with the windows (10d) of the outer basket (10), allow the passage of the cooling streams (X) towards the interior of the inner basket (20), to the product that is close to the bottom wall (20a) of the inner basket (20) which is subjected to the freezing streams (X) by the passage of these through the windows in the walls of the baskets thus, not only are these streams (X) exposed to the surface product, but the entire product is exposed to freezing conditions.; Once the period of exposure of the product to the cooling currents has been fulfilled. { X) to comply with the freezing treatment in the product, a wrapping material (¾), by means of known elements, such as automatic wrapping machines or by a wrapping process [manual; the above depends on the condition of the product, that is, in case the product in the internal basket (20) is in bulk, the process of enunciation will be manual; in the event that the product inside the inner basket (20) presents trays, the wrapping can be made in automatic machines1 for this purpose. The casing (y) in the internal basket (20) is completely adhered to the shape of the inner basket (10) as shown in Figure 7, so the importance of the internal basket body (20) not suffering alterations, and the wrapping material (and) being so resistant that rips are avoided in the next stage, for handling.

Once the internal basket (20) is wrapped, it is again placed inside the outer basket (10) to shape the package again as shown in Figure 8, hence, the wrapping material (y) it is suitable to avoid tears when sliding it into the outer basket (10).

The process is repeated for each of the packages with frozen product, to subsequently place a series of packages in a first level of external baskets (10) in a transport pallet, to subsequently subsequently stack more packages on the external baskets ( 10), each with an internal basket (20) and product frozen inside as can be seen in Figure 9. The number of levels of the stack of external baskets (10) will depend on the volume desired for a batch to be transported on a transport platform (50). i: With the above, the packaging is prevented. { W) of the pallet is made on the internal baskets (20) and said packaging (W) is made in the outer baskets (10), as shown in Figure 9; in addition, the load of the stack falls on the outer baskets (10) which are more resistant to the internal baskets (20), with which the fortuitous affectation of the wrapping is prevented (and realized to the internal baskets (20), avoiding currents of air that can generate condensations, and with this get to degrade the product, as well as the entrance of foreign agents to the products in bulk, which can represent a rejection factor who receives the shipment, generating waste due to inadequate. I Once in the premises of a distributor, the packaging of the transport pallet is opened to dispose the packages unitarily and once they are close to a temporary warehouse, such as a refrigeration tank, the inner basket is extracted (20). ) from the external basket (10) to place it properly in said temporary warehouse, with which the condition of hermeticity in the product is sought and in this same condition store it for as long as it is necessary for its subsequent disposal.

When you get to demand product, take one of the internad baskets (20) with frozen product and until then the wrapper of this internal basket (20) is opened, under hygienic conditions and proper for the handling of this type of products, determined by the person responsible for the subsequent handling.

? The above is carried out until the internal basket (20) is emptied, said inner basket (20) remaining under the guard of the person responsible for the subsequent handling, and then returned to the supplier of meat products or company.

I t packing through mechanisms defined between the client and the supplier. i: Once the internal basket (20) is returned to the supplier of meat products, it is subjected to a washing process to eliminate factors that may affect the product or its wrapping, and then return to the beginning of the packaging process
