Description
Technical Field
The invention relates to the technical field of food processing, in particular to a ventilating device for preventing rice dumplings from being half-cooked.
Background
The traditional festival of China is in the morning festival, the traditional custom of the festival is to eat the rice dumplings in the afternoon festival, the rice dumplings are food prepared by wrapping sticky rice and stuffing with bamboo leaves, the rice dumplings have the rice fragrance of the sticky rice and the faint scent of rice dumpling leaves, and the rice dumplings are favorite food. With the development of the times, the rice dumplings are not only eaten by people in the morning festival, but also become daily food for people, and people select the rice dumplings to not only require rich mouthfeel, but also require the natural raw materials and comprehensive and balanced nutrition, so that the rice dumplings are healthful to eat, and therefore, the improvement and innovation of the rice dumpling making are new subjects for people to make continuous efforts.
Along with the continuous improvement of the requirements of people on the rice dumplings, the very big rice dumplings gradually become the focus of attention of people. When banquet, activities or celebration festival, the very big zongzi not only can be appreciated by people, can also supply many people to eat together, shares the delicious taste of zongzi together. The zongzi must make the rice steam thoroughly through the processing of cooking in the manufacturing process, but the phenomenon that inside rice is not steamed easily appears in the zongzi in-process of cooking, and the zongzi presss from both sides the phenomenon of growing promptly, influences the taste of zongzi.
For solving above-mentioned problem, patent application No. CN201310609325.5 discloses a zongzi molding evaporates frame, including a disc, the periphery is impartial below the disc is equipped with three supporting legs, evenly all is equipped with a plurality of conical containers in the middle of above the disc, and disc and conical container are all evenly all equipped with the bleeder vent, the peripheral impartial fixed screens that corresponds with following three supporting legs that is equipped with above the disc, evaporate the frame and can be one deck or multilayer. Although this steam rack can avoid the zongzi to press from both sides the phenomenon of growing, its cooking that only is applicable to the zongzi of conventional size, nevertheless because the size of very big zongzi is great, and need to evaporate ripe rice and compare the quantity of conventional zongzi more, when adopting the steam rack to boil, the inside rice of big zongzi central authorities still can appear not steamed ripe phenomenon, has reduced the taste and the edible quality of big zongzi.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art, and provides the ventilating device which has simple structure and convenient use and can prevent the rice dumplings from being half-cooked.
The technical scheme adopted by the invention for solving the technical problems is as follows: the ventilation device comprises a pipe body, wherein the pipe body is prism-shaped or round table-shaped, the pipe body is of a hollow structure, a hollow cylindrical pipe is arranged in the center of the pipe body, a plurality of ventilation holes are formed in the pipe body and the cylindrical pipe, the bottom end of the cylindrical pipe extends into the pipe body, and the top end of the cylindrical pipe extends out of the pipe body.
Through being equipped with the bleeder vent on body and cylinder pipe, make this breather be located in the middle of the zongzi grain of rice when using, the steam that produces when making the zongzi cook can be followed this bleeder vent and effused to the zongzi inside, makes the zongzi inside be heated evenly, avoids the zongzi to appear pressing from both sides the phenomenon of growing in the in-process inside of cooking, has improved the taste of zongzi.
Further, the inner diameter of the pipe body is gradually reduced from the bottom surface to the top surface.
Further, the body is triangular prism shape.
Further, the pipe body is welded with the cylindrical pipe.
Further, the pipe body and the cylindrical pipe are detachably connected.
Further, the top of body still is equipped with the sleeve, be equipped with the internal thread on the sleeve, the bottom of cylinder pipe be equipped with internal thread assorted external screw thread.
Further, the height of the pipe body and the distance ratio between the top of the pipe body and the top of the cylindrical pipe are 1: 1.5, this proportion is applicable in cooking of very big zongzi, avoids the body to occupy the middle more area of zongzi, improves the content of the grain of rice in the zongzi to improve the taste and the comprehensive edible value of zongzi.
Further, the wall thickness of the pipe body is 1-3 mm.
When the wall thickness is less than 1mm, the pipe body is easily deformed by the expansion and extrusion of the rice grains outside in the cooking process of the big rice dumpling, so that the service life of the pipe body and the cooking quality of the big rice dumpling are reduced; when the wall thickness is larger than 3mm, the ventilation speed of the ventilation holes is reduced in the same time, the cooking efficiency is reduced, and the overall weight of the ventilation device is improved.
Preferably, the wall thickness of the tube body is 2 mm.
Further, the pipe body and the cylindrical pipe are made of stainless steel material.
The ventilation device for preventing the rice dumplings from being half-cooked has the beneficial effects that: according to the invention, the pipe body and the cylinder are arranged, and the air holes are formed in the pipe body and the cylinder pipe, so that the air ventilation device is positioned in the middle of rice grains of the rice dumpling when the air ventilation device is used, steam generated during cooking of the rice dumpling can be diffused into the interior of the rice dumpling through the air holes, the interior of the rice dumpling is uniformly heated, the phenomenon of half-cooked rice dumpling in the cooking process is avoided, and the taste of the rice dumpling is improved.
