Description

Technical Field

[0001] The present application relates to the technical field of food processing machinery, and in particular to a spray mechanism for a fryer. Background Art

[0002] Deep-frying is a cooking method. Over-frying produces polycyclic aromatic hydrocarbons (PAHs). Whether it's fried dough twists, spring rolls, and meatballs enjoyed during festivals, or the fried dough sticks, fried cakes, and flatbreads we eat for breakfast every day, or the French fries, fried bread, and fried chicken wings in fast food popular with children, or the potato chips and fried biscuits we eat as snacks, all are fried foods.

[0003] Due to the growing demand for food, deep-frying equipment has emerged. Existing deep-frying equipment is mostly assembly-line equipment, with stainless steel mesh cages attached to conveyor chains or cold dough dough placed directly on a conveyor chain, the middle of which is submerged in the frying chamber. The cold dough dough is then transported by the conveyor chain into the hot oil for frying and then drained. However, during frying, the cold dough dough is completely submerged in the hot oil in the frying chamber, resulting in a high amount of residual oil in the dough dough, which fails to meet the growing demand for healthier, less oily foods. Furthermore, this fully submerged frying method can easily result in a large amount of dough residue remaining in the hot oil. This method of frying often requires prolonged use of hot oil, which can rapidly produce substances such as acrylamide, trans fats, and benzopyrene. Excessive acidity can seriously harm human health.

[0004] Therefore, there is an urgent need in the art for a device that can fully fry the cold embryos of fried food without filling the frying box with enough hot oil to completely immerse the cold embryos of fried food. Utility Model Content

[0005] In order to realize frying of fried food without immersing the whole cold dough in hot oil, and reduce the possibility of residual fried oil residue in the frying box to produce harmful substances that affect human health.

[0006] The present application provides a fryer spray mechanism that adopts the following technical solution:

[0007] A spray mechanism for a fryer includes a hot oil tank, a suction pump, and a hot oil spray assembly.

The spray branch pipes extend into the frying box. Each spray branch pipe is located in a section inside the frying box and is evenly spaced along its own length direction. The spray heads are arranged toward the conveyor chain for the fryer.

[0009] Furthermore, two spray main pipes are arranged at intervals above and below, a fryer conveyor chain is arranged between the two spray main pipes, and the two spray main pipes are connected to the liquid outlet of the suction pump through a connecting pipeline.

[0010] Furthermore, a stop valve is connected between the suction pump, the hot oil tank and the spray main pipe.

[0011] Furthermore, a flow sensor is provided between the spray main pipe and the stop valve.

[0012] Furthermore, the hot oil tank is provided with an oil inlet connected to the frying box body, and a plurality of heating tubes are arranged in the hot oil tank. The heating tubes are provided with heating wires, and the heating wires are electrically connected to an external power supply.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meanings understood by persons having ordinary skills in the field to which this application belongs. The words "a" or "an" and the like used in the patent application specification and claims of this application do not indicate a limitation on quantity, but rather indicate the presence of at least one.

[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The embodiment of the present application discloses a spray mechanism for a fryer.

[0026] Reference Figure 1 and Figure 2A spraying mechanism for a frying machine includes a hot oil tank 1, a suction pump 2 and a hot oil spraying assembly 3. The liquid inlet of the suction pump 2 is connected to the hot oil tank 1, and the hot oil spraying assembly 3 is connected to the suction pump 2. The hot oil spraying assembly 3 extends into the frying box 13 and sprays hot oil on the cold food embryo in multiple directions and throughout the entire conveying process in the conveying direction of the cold food embryo. The frying box 13 is a ventilated box and the temperature inside is high due to the action of the hot oil. Through the action of hot oil spraying and high-temperature hot air, the food is fried into a crispy finished product, while the interior can maintain the moisture and nutrition of the ingredients, which is healthy and low in oil.

[0027] Reference Figure 1 and Figure 2 The hot oil spray assembly 3 includes a spray main pipe 31, a spray branch pipe 32 and a spray head 33. The spray main pipe 31 is installed with at least one and is connected to the liquid outlet of the suction pump 2. The spray branch pipes 32 are evenly spaced and connected to the spray main pipe 31 along the direction of conveying the cold food embryo. The spray branch pipes 32 and the spray main pipe 31 are integrally formed. In actual use, a plug hole is opened on the frying box 13, and the spray branch pipes 32 are inserted into the frying box 13 through the plug hole. At the same time, the spray main pipe 31 and the frying box 13 can also be fixed. A section of each spray branch pipe 32 is located in the frying box 13 and is evenly spaced along its own length. A plurality of spray heads 33 are installed. The spray heads 33 are arranged toward the conveying chain for the fryer. Specifically, the spray heads 33 are spray structural members installed by threaded connection. It is a prior art and will not be described in detail.

[0028] Furthermore, in this embodiment, two spray main pipes 31 are arranged at intervals above and below, and the fryer conveyor chain is located between the two spray main pipes 31. The two spray main pipes 31 are connected to the liquid outlet of the suction pump 2 through a connecting pipe 4. The suction pump 2 is connected to the hot oil tank 1 and the connecting pipe 4 through a stop valve 5 installed by a flange, which is convenient for controlling the on-off and flow rate of the suction pump 2. The arrangement of the upper and lower spray main pipes 31 can synchronously spray the fried food in the upper and lower directions through the spray head 33, so that the fried food is fried more evenly and fully.

[0029] Furthermore, a flow sensor 6 is installed on the communication pipe 4 between the spray main pipe 31 and the stop valve 5 to monitor the circulation flow of the hot oil so that the operator can adjust the hot oil flow through the stop valve 5 at any time.

[0030] Reference Figure 1 and Figure 2The hot oil tank 1 is provided with an oil inlet 11 which is connected to the frying box 13. The oil inlet 11 can be connected to the frying box 13 through a pipeline, or can be directly provided on the top of the hot oil tank 1 to receive the hot oil discharged from the frying box 13. It is set according to the needs, which is all existing technology and will not be described in detail. In this embodiment, taking the oil inlet 11 on the top of the hot oil tank 1 as an example, a plurality of heating pipes 7 are installed and arranged in the hot oil tank 1. The heating pipe 7 is a U-shaped heat exchange pipe. A heating wire 8 is installed in the heating pipe 7, and the heating wire 8 is electrically connected to an external power supply.

[0031] When in use, the power supply is supplied, and the current flows through the heating wire 8 to generate heat and then transfer the heat to the heating tube 7. The heating tube 7 heats the edible oil in the hot oil tank 1 to provide the hot oil required for frying.

[0032] Furthermore, a refueling port 12 is integrally formed on the hot oil tank 1, and the refueling port 12 is used to connect to an external automatic refueling device. A liquid level sensor 9 is installed in the hot oil tank 1. During the frying of cold pasta dough, the hot oil will be consumed due to the frying of the pasta, so the hot oil in the hot oil tank 1 will become less and less. Through the setting of the liquid level sensor 9 and the refueling port 12, edible oil can be automatically replenished during the food processing process, thereby greatly improving the processing efficiency.

[0033] Reference Figure 1 and Figure 2 The spray main pipe 31 is connected to a waste pipe 10. Specifically, the waste pipe 10 is installed on the connecting pipe 4. A sealing cap 101 is screwed on the waste pipe 10. The setting of the waste pipe 10 can discharge the waste oil through the suction of the suction pump 2 after the hot oil has been used for a period of time, thereby ensuring the safety of fried food. At the same time, when the hot oil in the hot oil tank 1 is emptied, the staff can also pull the hot oil tank 1 out from the bottom of the frying box to facilitate cleaning of the oil residue stains in the hot oil tank 1.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
