Method for heat-treating food materials
The invention provides a method for heat-treating food materials by using a food material heat-treating device. According to an embodiment of the invention, the method comprises: placing the food material to be heated on a food material bearing surface; injecting water into the water tank; and opening the heating component so as to carry out heat treatment on the food material to be heated, wherein the water tank surrounds the food material bearing surface and is in a spiral annular structure from inside to outside. Water in the water tank can be heated together in the process of heating the food materials, and water vapor formed by heating can supplement water lost by heating the food materials in time, so that the phenomenon of dehydration and hardness of the food materials is avoided. The water tank is arranged to be of a spiral annular structure, so that the heating area of water in the water tank is increased, evaporation is accelerated, and control is facilitated. Therefore, the method for heating the food material is simple, convenient and quick to operate, low in cost and suitable for wide application.
According to an embodiment of the present invention, referring to fig. 1, the food material heat treatment apparatus comprises: a body in which a heating space 100 is formed, wherein the heating space 100 includes: a food material bearing surface 110, the food material bearing surface 110 being disposed at the bottom of the heating space 100; a heating part 120 for heating the food material loaded on the food material loading surface 110; and a water tank 130, wherein the water tank 130 surrounds the food material carrying surface 110 and has a spiral ring structure from the inside to the outside.
The food material bearing surface is used for containing food materials to be heated, the water grooves are arranged around the food material bearing surface, water in the water grooves is heated together in the process of heating the food materials, the water in the water grooves is heated to form water vapor, the water lost by heating the food materials is supplemented in time, and the phenomenon that the food materials are dehydrated and hardened is avoided. Furthermore, the water tank is arranged to be of a spiral annular structure, so that the heating area of water in the water tank is increased, volatilization is accelerated, and control is facilitated. Therefore, the food material heat treatment device provided by the embodiment of the invention is ingenious and reasonable in structural design, is easy to realize, and has a great application prospect.
For convenience of understanding, the spiral annular structure of the water tank is divided into a plurality of annular parts, the annular part is marked as an annular part along a path which is rotated by a preset angle along the spiral annular structure by taking an inner side end as a starting point, then an end point of the annular part is used as a starting point of a new annular part, and the like, and when the annular part exceeds an outer side end of the water tank after the spiral annular structure is rotated by the preset angle by the starting point (the rotating direction of the whole spiral annular structure is consistent), the annular structure formed between the starting point and the outer side end is used as a last annular.
The heating member may be disposed on the upper portion or the side portion of the food carrying surface, as long as the food on the food carrying surface can be heated. The heating means is not limited to a strict heating method, and may be an electric heating method, such as microwave or infrared heating, a gas heating method, a wood or coal heating method, or any other heating method as long as it can heat the food material.
According to an embodiment of the invention, referring to fig. 2, the shortest distance D1 between the water trough and the outer edge of the food carrying surface is 1 cm. Therefore, water in the water tank is heated together in the food heating process, and the water in the water tank can contact food materials as soon as possible after being heated to form water vapor, so that the moisture can be supplemented to the food materials. If the distance is too large, more water vapor is lost in the process of diffusing to the surface of the food material, so that the food material cannot supplement water fully and timely, and the dehydration and hardening phenomena are easy to occur.
The shape of the food material bearing surface is not strictly limited, and the food material bearing surface may be a regular shape, such as a circle, a triangle, a polygon, or an irregular shape, and specifically, the shape may be flexibly selected according to actual conditions, and is preferably a circle. When the food material bearing surface is circular, D1 is the distance between the ring part at the innermost side of the water tank and the outer edge of the food material bearing surface; when the food bearing surface is triangular, polygonal or irregular, D1 is the distance from the vertex of the food bearing surface closest to the ring part of the innermost side of the water tank to the ring part.
According to an embodiment of the present invention, the shortest distance D2 between the water bath 130 and the side wall of the heating space 100 is 1 cm. Therefore, the water vapor formed by heating can be fully diffused to the surface of the heated food material. If D2 is too small, the formed moisture is easily diffused to the surface of the side wall, and condensed into water droplets after cooling, and thus cannot be diffused to the surface of the heated food material.
According to an embodiment of the invention, the distance D4 between two adjacent annuli of the sink is 0.5 cm. Therefore, the water in the water tank can be guaranteed to have a large enough heating area, and the formed water vapor can fully and timely supplement the lost part of the food material heating.
It should be noted that, the distance between each ring portion in the water tank may be equal or unequal, the present invention is not strictly limited, and may be flexibly selected according to the actual situation, as long as the distance between two adjacent ring portions is 0.5 cm.

Therefore, the position of the opened water outlet can be determined according to the surface humidity of the food material to be heated, so that sufficient water is effectively guaranteed to be heated and evaporated to form water vapor, the water lost by heating the food material is supplemented, and the phenomenon of dehydration and hardness is avoided.
As mentioned above, the spiral ring structure of the water tank is divided into a plurality of ring portions, each ring portion can be provided with a water outlet, all the water outlets on the water tank are sequentially marked as the 1 st water outlet, the 2 nd water outlet, … and the nth water outlet from inside to outside along the spiral ring structure, and N is an integer from 1 to N.
