SU1383062A1 - Container for underwater storage of food products - Google Patents

Abstract

The invention relates to means for storing and transporting perishable foodstuffs, primarily to methods of transporting chilled products of wild reindeer in permafrost conditions. The purpose of the invention is to expand the functionality by providing adjustment of the depth of the immersion and transportation to the place of consumption. The containers with products are immersed in the natural reservoir of navigable waterways at a depth with water temperature of 6 ° C, provided, for example, by permafrost conditions, and the product is contacted with running water through an intermediate waterproof shell. The container has floats 6 placed in housing 1, the mass of which can be adjusted during storage to change the immersion depth and, consequently, the storage temperature. The container is equipped with towing elements 10 for connection to the vehicle. 1 il. (Ls

Description

The invention relates to the storage ι of food products.

The purpose of the invention is the expansion of functionality by providing regulation of the depth of immersion and transportation to the place of consumption.

The drawing shows a container for products of slaughter processing of animals in permafrost areas.

The container consists of a cylindrical rigid body 1, made, for example, of a metal pipe, the streamlined shape of the covers 2 with through holes 3, floats 4 connected to the housing 1 by cables 5 · and additional floats 6 with an adjustable mask made of elastic material. Floats 6 are installed in compartments formed by partitions 7 and are equipped with individual pneumatic systems, including hoses 8, valves and compressor (not shown). Transported products are placed inside the housing 1 in sealed elastic shells 9. The movement of the container along the route is reported from a mechanized craft with traction elements 10.

Work with the container is as follows.

An empty container is installed at the point of primary processing of carcasses of animals, for example, wild reindeer in permafrost areas on the banks of the navigable river. In this case, the housing 1 is almost completely immersed in water and only one end with the open cover 2 is raised and rests on the river bank. Opposite cover is closed. Using floats 4 and 6 provide alignment of the housing 1 for the period of loading the container with hermetic shells 9 with the product. Mooring the container to the shore is carried out using traction elements

10. With this position of the container, it is easily loaded on the inclined surface of the housing 1 in the water inside it. After loading, the lid 2 is closed and the container is moved to the bottom of the river, installing in a stream of cold water until the arrival of a mechanized craft, such as a boat. The container is connected to it by means of traction elements 10. Then the pneumatic hoses 8 are connected to the pneumatic system mounted on the boat. Turn on the air supply from the compressor through the valves installed on the vessel, and carry out individually adjustable air filling of additional floats 6 in compartments separated from each other by partitions 7. At the same time, the trim of the container is eliminated (the difference in draft of the stern and bow of the container is zero) and set it to the depth corresponding to the minimum water temperature (0.6 ° C), taking into account the location of the navigable river or lake.

Since the container moves underwater, its location is visually determined by the outer floats 4, which simultaneously allow you to adjust the depth of immersion of the container and determine its trim. When approaching shallow water, air is supplied to the additional floats 6 in advance, which increases their volume and displaces the water ballast, due to whereupon the container pops up and acquires minimal draft (less than 1 m). After passing through the shallow water, the air in the additional floats 6 is partially removed and the container is again immersed to the required depth.

Unloading is carried out in the port by crane. After disconnecting the hoses and traction elements 10, the container is lifted out of the water, the lid 2 is opened, and the load along the inclined plane of the housing 1 arbitrarily enters the car body.

In the proposed device for maintaining a low temperature of chilled products of slaughter of animals, the natural cold of permafrost is used for rivers and lakes of natural reservoirs. Thus, absolutely no energy is required to maintain a low temperature of the products. While known transportation methods require the use of energy-intensive sources of artificial cold.

Since the product is hermetically sealed and, besides, it is under water, its contact with atmospheric oxygen is completely excluded and losses from natural loss (drying) are excluded, which significantly contributes to its preservation during transportation.
