Description

Technical Field

[0001] The utility model relates to the field of frying machines, in particular to a frying machine with uniform oil temperature. Background Art

[0002] A frying machine is a device used to fry instant noodle cakes. In the instant noodle production line, the instant noodles are placed in oil boxes with cake accommodating grooves driven by a machine. The machine drives the oil boxes to move in the strip-shaped oil pan, and the oil boxes will pass through the strip-shaped oil pan along the strip extension direction. When the oil box enters from one end of the strip-shaped oil pan and moves to the other end of the strip-shaped oil pan, the cakes in the oil box can be fried just right.

[0003] In the prior art, there is a snack food fryer disclosed in Chinese patent application No. 201420454322.9, which provides a specific structure of a fryer, as well as its working and use methods.

[0004] The outlet of the oil inlet pipe cannot be arranged along the strip extension direction of the strip oil pan, but can be arranged directly above the oil pan to make the oil temperature on both sides of the oil pan uniform. Because the instant noodle cakes will float on the oil surface during frying, a structure is required to press down the cakes in the oil box so that the cakes can be immersed below the liquid level of the oil in the oil pan. This downward pressing structure is arranged directly above the oil pan. The downward pressing structure will affect the oil inlet pipe from directly filling oil from the top of the oil pan. Therefore, the existing fryers all fill oil from one side of the oil inlet pipe.

[0005] One-sided oil inlet means that hot oil is added into the oil pan from one of the two sides of the strip-shaped oil pan in the strip-shaped extension direction, through a plurality of oil inlet pipes connected to the inside of the oil pan; and although the strip-shaped oil pan is long and has a large length-to-width ratio, the wide side of the oil pan has width after all. The oil temperature on the other side of the oil pan far from the oil inlet pipe outlet will be lower than the oil temperature on the side where the oil inlet pipe outlet is set, which leads to uneven oil temperature. Along the length of the wide side of the oil pan, a plurality of noodle holding grooves will be set in the oil box. Therefore, the noodle holding grooves are at different distances from the oil inlet, so the temperature is different, which leads to uneven frying of the noodles. Utility Model Content

[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. It should be noted that the terms used in the present utility model are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application.

[0022] The following describes the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] The noodle cake of fried instant noodles is a process in the production process of instant noodle cakes. In an instant noodle production line, a frying machine is a device used for the frying process of instant noodle cakes. Existing frying machines all feed oil from one side of the oil pan, which results in a higher oil temperature for the noodle cake on the side of the oil inlet close to the oil pan, while a lower oil temperature for the noodle cake on the side of the oil pan far from the oil inlet. As a result, the noodle cakes in the same batch are subjected to different oil temperatures, leading to different frying effects of the noodle cakes and large differences in the finished products. For industrial finished products, large differences in the noodle cakes as the same product are unqualified. To solve the above problems, the frying machine with uniform oil temperature provided in Embodiment 1 of the present utility model is as Figures 1 to 4 shown, and includes a strip-shaped oil pan 1 and a double-sided oil feeding device; the strip-shaped oil pan 1 includes a long strip-shaped cavity 11; a plurality of oil inlets 12 are formed on the strip-shaped oil pan 1; the oil inlets 12 are distributed on both sides of the long strip along the strip-shaped oil pan 1; the oil inlets 12 communicate the inside and outside of the cavity 11; the double-sided oil feeding device includes a hot oil providing device 21 and a plurality of oil delivery pipes 22; the oil delivery pipes 22 are communicated with the hot oil outlet of the hot oil providing device 21; one oil delivery pipe is communicated at each oil inlet.

[0025] When the frying machine with uniform oil temperature provided in Embodiment 1 of the present utility model is in use, it is necessary to first add oil into the strip-shaped oil pan 1 so that there is sufficient oil in the strip-shaped oil pan 1 to fry the flour cakes (the frying machine is a prior art, and the specific structure of the frying machine is disclosed in the Chinese patent application No. 201420454322.9 in the background art. This embodiment is an improvement based on its structure, and the rest of the structure of the frying machine will not be elaborated here). Control the frying machine to fry the flour cakes. During the frying process, it is necessary to timely supplement hot oil into the strip-shaped oil pan 1. In this embodiment, the hot oil is provided by the hot oil supply device 21 and enters the strip-shaped oil pan 1 through the oil inlet 12 on both sides of the strip-shaped oil pan 1 through the oil pipeline 22. Therefore, compared with the single-side oil inlet of the prior art, the device provided in this embodiment makes the distance between the flour cake and the oil inlet 12 more uniform for the strip-shaped oil pan 1 of the same size. Because of the single-side oil inlet structure of the prior art, the flour cake farthest from the oil inlet 12 has the width length of a strip-shaped oil pan 1, while in this embodiment, the flour cake farthest from the oil inlet 12 only has half of the width length of a strip-shaped oil pan 1. Therefore, each flour cake in this embodiment is evenly heated, the frying effect is similar, and the difference in the finished products is small.

[0026] For the frying machine with uniform oil temperature provided in the embodiment of the present utility model, during the frying process of the flour cake, the problem that the finished products vary greatly due to frying with oils at different temperatures can be solved, and the flour cake can be fried with hot oil at a uniform temperature, so that the difference in the finished products of the flour cake is small.

[0027] As a preferred solution, in this embodiment, the oil inlets 12 are symmetrically distributed on both sides of the strip-shaped oil pan 1 in the bar extension direction.

[0028] For the convenience of controlling the on-off of the oil circuit at each oil pipeline 22, as a preferred solution, in this embodiment, the oil pipeline 22 includes an oil outlet valve 221 and several pipelines 222; the inlet end of the oil outlet valve 221 is connected to the hot oil supply device 21 through the pipeline 222; the outlet end of the oil outlet valve 221 is hermetically connected to the oil inlet 12 through the pipeline 222. By controlling the oil outlet valve 221, the on-off of one oil pipeline 22 can be opened and closed, which is convenient for the maintenance of this oil pipeline 22 and the oil inlet 12 connected thereto when a problem such as blockage occurs in a single oil pipeline 22.

[0029] The frying machine needs to be cleaned and maintained periodically. To facilitate the maintenance of the frying machine, in this embodiment, an oil drain port 223 is provided on the oil delivery pipeline 22; the oil drain port 223 is provided on the pipeline 222 communicating between the outlet end of the oil outlet valve 221 and the oil inlet 223; the oil drain port 223 is provided at the bottommost of the pipeline 222; an oil drain valve 2231 is provided at the outlet of the oil drain port 223. By opening the oil drain valve 2231, the oil remaining in the oil delivery pipeline 22 will be discharged from the oil drain valve 2231 preferentially, avoiding the spraying of the oil remaining in the oil delivery pipeline 22 when the oil delivery pipeline 22 is disassembled and cleaned, so that the waste oil falls to the ground or onto the staff, affecting the movement of the staff and the progress of the maintenance work of the staff.

[0030] As a preferred solution, in this embodiment, the oil delivery pipeline 22 and the oil inlet 12 are connected by a flange 3. Flange connection is a common form of connection between pipelines. In this embodiment, the oil delivery pipeline 22 and the oil inlet 12 are connected by the flange 3, so that the oil delivery pipeline 22 and the oil inlet 12 are communicated; when the oil inlet 12 is blocked, the connection at the flange 3 can be disconnected to clean the oil inlet 12. When the blockage in the oil delivery pipeline 22 is serious, an oil delivery pipeline 22 can be directly replaced to enable the frying machine to complete the maintenance quickly and resume production.

[0031] As a preferred solution, in this embodiment, the hot oil supply device 21 includes a heat exchanger 211, a drain pipe 212, an oil tank 213 and a pump; the heat exchanger 211 includes a cold oil inlet 2111 and a hot oil outlet 2112; a pump is provided at the oil outlet of the oil tank 213; the oil outlet of the pump is connected to the cold oil inlet 2111 through a pipeline; the hot oil outlet 2112 is connected to the drain pipe 212; the drain pipe 212 is connected to the oil pipeline 22. There are many ways to provide hot oil, such as directly heating cold oil. In this embodiment, a heat exchanger 211 (preferably a steam heat exchanger) is used to quickly heat the oil. The heat exchanger 211 is a prior art and will not be elaborated here. In this embodiment, the pump is used to move the oil in the oil tank 213 into the heat exchanger 211 for heating (the specific structure and method of the pump, the oil tank, and the pump pumping out the oil in the oil tank are prior arts and will not be elaborated here). The heated oil flows out from the hot oil outlet 2112 and enters the drain pipe 212, and the hot oil is transported through the drain pipe 212 (in the drain pipe 212, the oil is in a closed environment and the oil temperature changes slowly, while above the oil pan, the oil pan is open, so the oil temperature changes quickly. Therefore, the distance of the oil in the drain pipe 212 from the heat exchanger 211 has little effect on the temperature, and after entering the strip-shaped oil pan 1 from the oil inlet 12, the distance from the oil inlet 12 has a great impact on the oil temperature change). In this embodiment, the drain pipe 212 is arranged vertically above the strip-shaped oil pan 1, and the drain pipe 212 is arranged along the strip extension direction of the strip-shaped oil pan 1. The drain pipe 212 is connected to the oil pipeline 22. The oil pipeline 22 first extends perpendicular to the extension direction of the strip-shaped oil pan 1, then extends vertically downward, and finally extends along the direction perpendicular to the extension direction of the strip-shaped oil pan 1 to set the pipeline 222, and is connected to the cavity 11 of the strip-shaped oil pan 1 from the side of the strip-shaped oil pan 1. Such a setting of the oil pipeline 22 is to avoid affecting the mechanism for pressing the dough cake of the fryer; in this embodiment, the drain pipe 212 is preferably arranged vertically above the midline of the strip-shaped oil pan 1, which makes the oil pressures at the two symmetric oil inlets 12 similar. By controlling the oil outlet valve 221, the oil flow rate at the oil inlet 12 can be further adjusted, so that the oil flowing out from the symmetric oil inlets 12 converges at the midline of the selected oil pan 1, thereby minimizing the oil temperature difference received by the dough cake in the strip-shaped oil pan 1.

[0032] In summary, the present utility model provides a frying machine with uniform oil temperature, which relates to the field of frying machines and includes a strip-shaped oil pan and a double-sided oil inlet device; the strip-shaped oil pan includes a long strip-shaped cavity; a plurality of oil inlets are provided on the strip-shaped oil pan; the oil inlets are distributed on both sides of the long strip along the strip-shaped oil pan; the double-sided oil inlet device includes a hot oil providing device and a plurality of oil delivery pipes; the oil delivery pipes are communicated with the hot oil outlet of the hot oil providing device; one of the oil delivery pipes is communicated at each oil inlet.
