Definitions

  • the present invention relates to the technical field of furniture, showcases or stalls in the general sense for the refrigerated presentation of food products and more specifically to a display stand for food products especially fresh and especially fish, meat or cheese.
  • a stall comprising a presentation tray supported by a base and having a bottom from which rises a peripheral rim forming a box for receiving on a bed of ice, fresh products such as fish .
  • This stall offers an optimized presentation of fresh produce sold by dedicated personnel.
  • the hygrometry of such a stall must be controlled to prevent fresh products from being dried or drenched with water.
  • the patent EP 1 138 230 describes a refrigerated display of products, particularly food products, of the type comprising an enclosure delimited by side walls and a bottom to form a tank provided with a discharge outlet, the enclosure containing a presentation tray products part of a containment tank, forming part of a containment tank for a cooling material, provided with an outlet for liquid products, this presentation tray separating said enclosure into an upper zone of exposure of the products and a functional lower refrigeration zone of the air circulating in a loop thanks to a ventilation system forming part of an evaporator, of a refrigerating installation, with a flow of air flowing over the plate and a return air flow circulating below the plateau.
  • the lower area below the tank is free of any functional objects in order to maximize its air holding capacity so that the fan can blow moist air at the beginning of the cooling cycle, in order to avoid the drying of fresh products.
  • Such a stall allows, at the beginning of the cooling cycle, to maintain at a storage temperature exclusively fresh food products presented on a bed of ice and cooled by a refrigeration system dimensioned accordingly.
  • a refrigerated showcase comprising an enclosure delimited by side walls and a bottom to form a tank provided with a discharge outlet.
  • the enclosure contains a mobile product presentation tray, separating said enclosure into a higher area of fresh packaged product exposure and a functional lower refrigeration zone of circulating air through a ventilation system, with a flow of air flowing over the plateau and a return airflow flowing below the plateau.
  • the functional lower zone is adapted to house an evaporator forming part of a refrigeration installation and mounted downstream of the ventilation system in consideration of the direction of flow of the air flow.
  • a refrigerated showcase is particularly suitable for presenting packaged food products available in self-service. These food products which are enclosed for example in trays, do not present any risk of degradation by drying.
  • the upper zone of exposure of packaged fresh products has a uniform temperature throughout its volume due to the ventilation of cold air at a temperature suitable for the preservation of products.
  • More and more sales areas include a refrigerated display of fresh products on a bed of ice, but also a refrigerated display of fresh produce packaged to meet the needs of consumers for purchases of fresh products at a time.
  • self-service and assisted sales leads to difficulties in managing supplies of products intended to be marketed on an ice bed or in a packaged manner. It also turns out that these stalls occupy a large sales area while the quantities of purchases of fresh products in self-service and assisted sales are very variables according to the days of the week.
  • the marketing mode of fresh products in self-service concerns a sale which requires competent personnel difficult to find whose skills should be optimized as close as possible to the commercial activity.
  • the patent application JP 2011 169590 describes a stall equipped with a refrigeration plant whose power is modulated according to the food products present in the stall.
  • the present invention therefore aims to overcome the drawbacks of the prior art by proposing a new refrigerated display to present on demand, fresh products available either self-service or assisted sales, while keeping these products at the temperature required with a hygrometry rate adapted to preserve all the qualities with these fresh products.
  • Another object of the invention is to provide a refrigerated stall for moving quickly and easily from a fresh produce sales stand to a sales stand for self-service products, and vice versa.
  • refrigerated stall according to the invention allows a sale of fresh products self-service Monday through Thursday for example and an assisted sale, from Friday to Sunday.
  • the object of the invention relates to a refrigerated display of products, particularly foodstuffs, of the type comprising an enclosure delimited by sidewalls and a bottom to form a tank provided with an outlet of evacuation, the enclosure containing a presentation tray of the products forming part of a containment tank for a cooling material, provided with an outlet for liquid products, this presentation tray separating said enclosure into an upper exposure zone products and a functional lower zone of refrigeration of the air circulating in a loop thanks to a ventilation system forming part with an evaporator, of a cooling system with a flow of air flowing over the plateau and a return airflow flowing below the plateau.
  • the stall according to the invention allows a versatile organization of the sale of fresh products either self-service at certain times of the week or assisted sales at other times of the week. This switching from one mode of sale to another being very simple and easy to achieve, the stall can be transformed into the beginning, in progress or at the end of the day.
  • the offer for sale makes it possible to respond to significant variations in sales volumes by adapting to the needs of consumers and by optimizing the needs for personnel dedicated to marketing.
  • the stall according to the invention has for each mode of sale, optimized conditions to keep the fresh products in the best conditions of temperature and hygrometry.
