Abstract

Vat (1) for reheating cooked food in bags (7), said vat (1) being filled with hot water maintained at an approximately constant temperature in which the bags (7) are immersed, the vat being characterised in that beneath the bottom (2) of the vat (1) there are means (3) for generating a revolving field and in that in the bottom of the vat is a free magnetic bar (4) which is driven round by the revolving field. Faster reheating of bags (7) and a hygienic apparatus.

Description

Food reheating tank provided with means for stirring hot water.

 The present invention relates to a tray for reheating cooked dishes contained in pockets, said tray being filled with hot water maintained at a substantially constant temperature in which the pockets are immersed.

 The cooked dishes contained in the pockets are thus reheated without being annealed.

 The water is brought to a constant temperature which can be 680C for example for fish and red meats and 750C for other meats or other dishes.

 However, the inventors have observed that thin air bubbles are deposited around the pockets, thus constituting a true insulating film.

 The container according to the invention making it possible to break this film and to ensure a faster reheating of the pockets, is characterized in that under the bottom of the container are arranged means generating a rotating field and in that in the bottom of the tray is arranged a free magnetic bar rotates by the rotating field.

 In addition, this system allows very good hygiene since in the event of a pocket rupture the food is not entrained out of the tray and the bar is very easy to clean.

 According to a preferred embodiment of the invention, the bar is covered with P.T.F.E (teflon R) and the tank is provided with a grid disposed above the bottom and preventing the magnetic bar from coming into contact with bodies immersed in hot water.

 The invention will now be described in more detail with reference to two particular embodiments cited by way of nonlimiting example and shown in the accompanying drawings.

 Figure 1 shows a container according to the invention in section.

 FIG. 2 represents a top view of FIG. 1.

 Figure 3 shows a tray with a basket containing pockets to reheat.

 FIG. 4 represents a variant of the container according to the invention.

 The tank 1 of parallelepiped shape shown in Figures 1 to 3, is a stainless steel tank filled with hot water at 680C for example and maintained at this temperature by a circuit not shown.

Under the bottom 2 of the tank 1 are arranged four electromagnetic coils 3 used to generate a rotating horizontal field
At the bottom of the tank 1 is disposed a small teflonized magnetic bar 4 under a grid 5 parallel to the bottom 2 of the tank 1. This grid prevents objects immersed in hot water coming into contact with the bar.

 These objects are for example baskets 6 in which there are the pockets 7 containing the cooked food (see Figure 3).

 When the coils 3 are fed, the generated field entrains the bar 4 in rotation (see FIG. 2) and the water is agitated preventing the formation of a vapor film on the surface of the pockets 7. The cleaning of the tank 1 thus that the bar 4 and the grid 5 is very easy (bar 4 and grid 5 passing through a washing machine) which allows perfect hygiene.

 According to a variant shown in FIG. 4, the four electromagnetic coils are replaced by a motor 8, the axis of which is fitted with a horizontal N'S 'magnetic bar 9.
