GRILL, TRAY AND CART SYSTEM TO FREEZE FOODS

Abstract

A rack and carts system to hold salmons, trouts and any other kind of similar fish, in a way that a maximum freezing capacity is reached per tunnel (kilos of frozen product per hour) as well as an excellent product presentation.

Description

APPLICATION FIELD

The present invention refers to rack (trays) cart system and carts for freezing food, preferably fish, so as the products are frozen with high symmetry, also the freezing efficiency (capacity) of a semi-continuous or continuous static tunnel is maximized.

The aforementioned assures a better food presentation to the end consumer, especially in markets which reward the shape (symmetry) of the product, as for instance in Japan and, on the other hand, it allows to increase in about 30% to 40% the product nominal capacity of being frozen.

BACKGROUND OF THE INVENTION

Nowadays, there are several ways of freezing salmon, trout and other similar fish, whole gut fish, all those ways having different efficiency levels both in the freezing speed (equipment consistent capacity) and in the end-product quality (symmetry, aesthetics)

The present invention discloses a type and trays for freezing, preferably Salmon Hg type (gutted fish without head), also applicable to the freezing of any food product so as to achieve the maximum freezing capacity in a classic semi-continuous tunnel but keeping a good symmetrical and aesthetic presentation which makes it much more attractive for sophisticated markets.

Currently, in the salmon farming industry there is no plant achieving maximum freezing capacity, and at same time obtaining an impeccable product presentation, one aspect must be always compromised in order to benefit the other. By means of this innovation it is feasible to combine both aspects reaching record freezing capacity levels and a presentation which makes the end product much more attractive, especially for demanding end consumers.

In the salmon farming industry, the freezing capacity of gutted fish without head, has historically been a struggle among the systems freezing large volume of kilos per hour (productivity of the process) and those allowing the aesthetic of the end product to be impeccable (selling price maximization). There are markets which recognize the importance of the second aspect and this has resulted in that, at an industrial level the freezing capacity has been compromised for the sake of a symmetrical product accepted by those markets.

This innovation consists of a freezing system of the product which combines both aspects, that is, maximum capacity and an excellent product presentation. Once this is achieved, a substantial competitive advantage would be obtained by means of the existing alternative technology to that end, which also results in an important reduction of the freezing costs which besides making this innovation more competitive allows to reduce the required power to that end, and consequently the detrimental effect produced, by said technology in the environment.

The created technology considers a rack and carts system to hold salmons, trouts and any other kind of similar fish, in a way that a maximum freezing capacity is reached per tunnel (kilos of frozen product per hour) as well as an excellent product presentation.

DETAILED DESCRIPTION OF INVENTION

In order to carry out the previously mentioned objectives, as well as others is that according to a practical embodiment, as shown in FIG. 1, the freezing device comprises the rack, preferably made of stainless steel in which the frame supporting the whole tray has a tubular shape with a square section. (FIG. 2). Inside of said frame, there is a series of units which can serve as a base for the product to be frozen. Said structures, also preferably made of stainless steel are formed by a solid in-tube which protrudes the tray in a close-curve shape (FIG. 3) with a protruding end which supports, for instance, previously gutted fish without head. The same configuration contains a curved-laminar section which can be used as a support for the tail section of a fish-like type (FIG. 4). Both the length of the support section and the angle of the section previously described are relative and will depend on the product to be frozen. With this Innovation, the fish are vertically arranged with respect to the ground (FIG. 5). Particularly, for freezing salmon, 9 arrangements by side are suggested of a total of 18, achieving an appropriate distance between one and the other, thus avoiding contact among the units to be frozen, which means they do not stick to each other, thus allowing that the whole mass to be frozen is uniformly and independently subject to the effects of cold, obtaining an uniform and even freezing.

The previously described curve and tail support configurations are arranged on the tray so as the tail supports are arranged (placed) inwards alternately in order to optimize the load capacity of each tray (FIG. 6).

Then, on the one hand, the curved solid section has a length such it allows to fit the fish or the like being held by their weight and collar bone which divides the ventral body cavity from the head zone and, on the other hand, the curved laminar surface has an extension such that it allows supporting the tail or lower side of the fish or the like without leaving a mark of said support, and allowing to vertically hold the unit so as this is not laid on one of its sides.

According to one practical use of the first embodiment of the invention, the part of the curved solid preferably has a length of 190 mm, while the tail support preferably has a length of 100 mm and the space between them is of about 100 mm (FIG. 7) thus forming in this position a compact group which reaches 390 mm of total length.

These and other objectives, characteristics and advantages of the present invention can easily noticed in the detailed description which leads the best way of carrying out the invention when taken in combination with the attached drawings.
