Description

Food tray support pull-out rotary hot/refrigerated catering car {CATERING CART}

According to the present invention, food trays (food trays) are accommodated and can be moved to a specific place, and food trays are placed in the space of the cabinet in a state where food that needs to be kept warm and food that needs to be kept cold are stored in the food tray. It is about a hot/cooled hot/refrigerated catering car that can maintain the appropriate temperature for the food by operating the corresponding module when stored in the food tray. Technology related to a pull-out rotatable hot/refrigerated food tray support for food trays that can be rotated at a certain angle to facilitate hygienic management by cleaning the inside of the cabinet as well as the configuration of the pull-out and rotated supports to be.

In general, when group meals are provided for a large number of people such as large restaurants, schools, military, training centers, campsites, hospitals, etc. Since the food must be delivered directly, the food prepared in the food service room is placed on a plate for each tens of servings, stored in a multi-layered stacking state in a food distribution car with multi-layered shelves, and prepared for distribution. Distributed food is distributed to each ward while transporting and moving food trucks to each ward at once. At this time, cooked food is usually placed on the delivery car and then supplied to the final patients, taking as little as 1 hour and as long as 2 hours. It takes a while.

And in the process of waiting for a long time, for example, soup, rice, or baked, boiled, or fried food that should be kept in a warm state is easily cooled, and conversely, for example, fruit, milk, or vegetable food that should be kept in a cold state. As it heats up easily, its freshness deteriorates, so there is a problem of nutritional loss, as well as not providing enough nutrients to patients with poor appetite.

To improve this, food trays with hot and cold functions have begun to appear, and these cold and hot food trays function as a central partition wall, that is, to insulate between the cold room and the hot room, as well as a partition wall that serves as a support for the plate to sit on. This crossbar or crossbar has a disadvantage in that it is firmly fixed to both walls and has a structure that is not easy to detach, so it is difficult to clean and sanitary is poor when used for a long period of time.

In order to solve the above-mentioned problem, as a technology for easily cleaning the plate support of the food tray and its surrounding area,
