Description

[Detailed Description of the Invention] The present invention relates to a convenient roaster capable of uniformly roasting potatoes, chestnuts, ginkgo nuts, etc., and its construction will be detailed as follows with reference to the accompanying drawings.

A flame cylinder 2 is arranged upwardly in the center of the bottom of a cast metal container 1, and a series of protrusions 3 and grooves 4 are alternately formed on the bottom of the container 1, the inner surface of the peripheral wall, and the outer peripheral surface of the flame cylinder 2. Form radially.

The center of this container 1 is recessed downward, and this recessed portion 5
A heavy metal lid 7 also made of cast iron and formed into a curved surface 6 on the upper side is fitted between the upper side and the outer peripheral edge.

In the figure, 8 is a handle of the container 1, 9 is a handle of the metal lid 7, 10 is an annular heat shielding wall, and 11 is a pressure release hole.

Since the present invention is constructed as described above, when potatoes are placed on the bottom surface around the flame cylinder 2 of the container 1, the metal lid 7 is fitted, and the present invention is placed on a gas stove and burnt, the second flame is generated. As shown by the arrow shown in the figure, the flame enters from the flame tube 2, hits the top of the metal lid 7, and the flame that hits the lid 7 moves outward along the curved surface 6, and then downwards along the inner surface of the peripheral wall of the container 1. The flame moves to the top, passes through the bottom, and rises again, causing the flame to circulate inside the pot.

Therefore, the heat effect is good, and the heat is not wasted.
Since the back side is steamed and baked evenly, the whole thing will be baked evenly.

In particular, in this case, a series of protrusions 3 and grooves 4 are alternately formed radially on the bottom surface of the container 1, the inner surface of the peripheral wall, and the outer surface of the flame tube 2, so that the potatoes do not stick tightly to the bottom surface. The flame is placed on the convex strip 3, and the flame passes through the concave strip 4, and the flame is circulated very smoothly and there is almost no stagnation of the flame, which further prevents scorching and creates a uniform flame. It will be baked.

By making this metal lid 7 heavy, such as cast metal, it has good adhesion to the container 1 and can be expected to have a heat retention effect, so there is no waste of energy and the heat penetrates into the core of the potatoes, allowing them to be baked well. Moreover, since the metal lid 7 itself is heavy, it will not be lifted by steam pressure even during use, and will be in a steamed state.

Of course, this product can be used as a regular pot, and by adding water and a perforated plate, it can also be used as a steamer with excellent thermal effects. .
