Description

MULTI-PLATE ROTARY DISPLAY

It is known that the evolution of attitudes and consumption patterns tends towards a minimum of intervention of the personnel of the restoration and the reduction of the times of consumption for the majority of the populations.

Thus, for all those involved in catering, the aim is to facilitate and minimize meal preparation times, staff interventions in the service and consumption time for the clientele.

These developments, whether they are positive or negative, are undeniable facts and facts that all players in the catering sector of today's society must adapt to.

Some who have understood their interest in this evolution have adopted the fastfood mode which, as its name suggests, is geared towards speed of consumption, sometimes even at the expense of the nutritional quality of the food offered.

Thus, to adapt and meet the imposed evolution criteria, lunch and / or dinner were restricted to the sandwich whether in the form of Hamburger or any other form.

Thus, in this type of consumption, the restaurant owner has adapted and designed all the technical means to go fast and the consumer has agreed to transform his usual breakfast including most often an appetizer, a main course, a cheese and a dessert, a sandwich of fries and a pastry.

Although it is difficult to challenge the nutritional quality of food itself because it is seriously analyzed and controlled, it is the consumption pattern of the populations that seems to be changing very badly, the consumer not limiting himself more to eat a meal three times a day but several sandwiches throughout the day and without the slightest regularity.

Although the Fastfood mode offers the consumer, in a very short time, a set of products that can constitute a meal, it should be noted that the food is prepared in series at a specific place in the restaurant and maintained at a temperature close to the temperature of consumption (hot or cold) in equipment provided for this purpose on the place of preparation. Food are then delivered to the customer at a temperature close to the consumption temperature and resume the ambient temperature during consumption. Hot foods cool down and cold foods warm up depending on the duration of consumption. The consumer therefore has every interest in consuming quickly to consume at a good temperature. This characteristic is however not very felt by the consumers because the concerned food is far from the gastronomic kitchen and the time saving criterion takes precedence over the quality of consumption.

In order to adapt to changing consumption patterns, some actors have preferred to act in the direction of accelerating service and consumption, but by offering food that is closer to the one most often consumed at home as for example, ready-to-go pasta, rice in take-away sauce, soups etc.

This way obviously satisfies the criterion of speed but restricts the consumable to a single type of preparation and a single recipe even if the product can be embellished in a different way thanks to the sauces and condiments.

This particular mode of distribution and consumption of food in turn has the same disadvantages as the consumption mode previously exposed but also the inconvenience of being able to consume only one dish between two services.

Other restaurant operators have focused their development on the preparation and distribution of national specialties such as Pizzas, Chinese dishes and other sushi. If this culinary orientation brings the approval to be able to consume food of various and varied countries, it does not escape the drawbacks of all the modes of consumption to date proposed either:

The preparation and temperature setting of the dishes in a specific place and reserved to deliver them cooked at the consumer's table in another place, involving the multiplicity of services and the degradation of consumption temperatures during the meal.

We know that equipment intended to maintain food temperatures exist, are implemented and exploited for many years in agribusiness. The evolution of sanitary standards has led to the creation of many fixed facilities, particularly in the presentation and marketing of foods in specialized stores such as refrigerated display cases or display counters in large-area stores.

Much progress has been made in this particular sector, but almost all of the equipment offered concerns the provision of food or prepared meals to the public in self-service.

Thus, it is common to find in the catering sector, refrigerated or compartmentalized cabinets with hot compartments and associated cold compartments in which consumers can take the dish of their choice to the optimum temperature of consumption or conservation. These cabinets are sometimes even equipped with moving means such as for example wheels.

In this respect, mention may also be made of the PFEFFER patent filed in France on June 2, 1976, which was the subject of an addition of December 3, published on June 30, 1978 under the number FR 2 372 611, which mentions a display for toasts, pastries and analogous foods. This patent relates mainly to the method of manufacturing different trays designed to partially fit into each other. It is further characterized in that each tray is made to receive directly food such as amuse-mouths fixed on peaks provided for this purpose.

In a different mode, it can be noted the French patent THIERCELIN published April 23, 2010 under the number FR 2 937 234, which relates to a mobile display consisting of rotating elements around a central column, each element being made to hold a plate.

It can also be noted the Korean International Patent HWANG published under the number W09322949 which mentions a rotating display.

As a complementary state of the art, mention may be made of JP2004173896, WO2011 / 026535, EP1522240 and US1478217.
