Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, and in particular to a dual-circulation oil pan system. Background Technology
[0002] In the food processing industry, some products require deep-frying. The oil in the oil pan flows and is heated in a circulation pipe, then enters the oil pan to fry the products inside. After frying, the oil flows back into the circulation pipe, is filtered, reheated, and then returned to the oil pan.
[0003] Products need to be introduced into different temperature zones sequentially during frying to achieve optimal frying results. However, the aforementioned oil fryer systems typically only have a single oil inlet and outlet, making it difficult to achieve zoned oil temperature control throughout the entire fryer.

Detailed Implementation
[0013] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0014] Example 1: like Figure 1 As shown: This utility model provides a dual-circulation oil pan system, including a pan body, a first oil circulation component, and a second oil circulation component. The internal space of the pan body includes a first frying chamber 1 and a second frying chamber 3, wherein: the first frying chamber 1 corresponds to the front stage of the dual-circulation oil pan system; the second frying chamber 3 corresponds to the rear stage of the dual-circulation oil pan system; the first frying chamber 1 and the second frying chamber 3 are connected front and rear in the production direction; the first oil circulation component is circulatedly connected to the first frying chamber 1; the first oil circulation component is used to circulate hot oil to the first frying chamber 1; the second oil circulation component is circulatedly connected to the second frying chamber 3; the second oil circulation component is used to circulate hot oil to the second frying chamber 3.
[0015] When using the dual-circulation oil pan system provided by this utility model to fry products, the products first enter the first frying chamber 1 from the front. The oil temperature in the first frying chamber 1 is mainly controlled by the first oil circulation component. The oil in the first frying chamber 1 circulates in and out of the first oil circulation component. The first oil circulation component filters and heats the incoming oil before discharging it back into the first frying chamber 1. While frying, the products in the first frying chamber 1 continuously move along the production direction to the second frying chamber 3. In the prior art, the movement of the products generally uses a conveyor belt or a propulsion device. Since the method of product movement in the oil pan is prior art, it will not be elaborated further here. When the products enter the second frying chamber 3, the oil temperature there is relatively higher than that in the first frying chamber 1. The oil temperature in the second frying chamber 3 is mainly controlled by the second oil circulation component. The oil in the second frying chamber 3 circulates in and out of the second oil circulation component. The second oil circulation component filters and heats the incoming oil before discharging it back into the second frying chamber 3. After completing the frying process in the second frying chamber 3, the products enter the next processing stage.
[0016] This invention provides a dual-circulation oil pan system that uses a first oil circulation component and a second oil circulation component to heat different areas within the pan. This allows for precise control of the oil temperature differences between the first frying chamber 1 and the second frying chamber 3, meeting the varying oil temperature requirements of products during frying. Furthermore, the dual-circulation structure accelerates oil circulation and, through more circulation inlets and outlets, covers a wider area within the pan, ensuring that areas with slower oil circulation can effectively participate in the circulation process. This prevents oil buildup and carbonization, effectively improving oil lifespan and frying results.
[0017] As a specific implementation of the first oil circulation component, in a preferred embodiment, the first oil circulation component includes a first oil inlet pipe 2, a first oil outlet pipe 11, a first filter component 12, and a first heating component 13, wherein: the oil outlet end of the first oil inlet pipe 2 is connected to the first frying chamber 1; the oil inlet end of the first oil outlet pipe 11 is connected to the first frying chamber 1; the oil inlet end of the first oil inlet pipe 2, the first heating component 13, the first filter component 12, and the oil outlet end of the first oil outlet pipe 11 are connected in series and form a first circulating oil circuit with the first frying chamber 1.
[0018] When the first oil circulation assembly operates, the oil in the first frying chamber 1 first enters the inlet of the first oil outlet pipe 11 (the first oil circulation assembly is equipped with a pump body, which can provide suction to draw in the oil; this is prior art and will not be described further, the second oil circulation assembly works similarly), then flows sequentially from the outlet of the first oil outlet pipe 11 into the first filter assembly 12 and the first heating assembly 13 for filtration and heating, and finally flows back to the first frying chamber 1 from the first oil inlet pipe 2. The inlet of the first oil inlet pipe 2, which connects to the first frying chamber 1, can be located on both sides of the first frying chamber 1. By allowing oil to enter from both sides simultaneously, the uniformity of oil temperature can be further improved.
[0019] To facilitate adjustment of the oil temperature gradient, in a preferred embodiment, the oil outlet of the first oil inlet pipe 2 includes a first oil outlet 21 and a second oil outlet 22; the first oil outlet 21 and the second oil outlet 22 are arranged sequentially along the production direction. The first oil outlet 21 and the second oil outlet 22 are spaced reasonably according to the length of the oil pan and the requirements of the frying process, and both the first oil outlet 21 and the second oil outlet 22 are equipped with temperature detection points, providing a wider temperature detection range, which can be adjusted in real time according to the detected temperature.
[0020] The dual-circulation oil pan system provided by this utility model can improve the uniformity of oil temperature and make it easier to adjust the oil temperature gradient by setting the first oil outlet 21 and the second oil outlet 22 at intervals.
[0021] In a preferred embodiment of this invention, the second oil circulation assembly includes a second oil inlet pipe 4, a second oil outlet pipe 31, a second filter assembly 32, and a second heating assembly 33. The oil outlet of the second oil inlet pipe 4 is connected to the second frying chamber 3; the oil inlet of the second oil outlet pipe 31 is connected to the second frying chamber 3; the oil inlet of the second oil inlet pipe 4, the second heating assembly 33, the second filter assembly 32, and the oil outlet of the second oil outlet pipe 31 are connected in series and form a second circulating oil path with the second frying chamber 3. When the second oil circulation assembly is working, the oil in the second frying chamber 3 enters the circulation path from the second oil outlet pipe 31, and is filtered and heated sequentially by the second filter assembly 32 and the second heating assembly 33, finally flowing back to the second frying chamber 3 from the second oil inlet pipe 4.
[0022] Since the product needs to avoid uneven oil temperature leading to excessively high local temperatures during the frying stage in the second frying chamber 3, the distribution of the oil path needs to be further refined. In a preferred embodiment, the oil outlet of the second oil inlet pipe 4 includes a third oil outlet 41, a fourth oil outlet 42, and a fifth oil outlet 43; the third oil outlet 41, the fourth oil outlet 42, and the fifth oil outlet 43 are arranged sequentially along the production direction. The third oil outlet 41, the fourth oil outlet 42, and the fifth oil outlet 43 are arranged sequentially at a set interval. By introducing oil into the second frying chamber 3 at multiple points, the uniformity of oil temperature can be effectively improved. Since the second frying chamber 3 requires a longer frying time, the stroke is longer. Therefore, compared to the first oil inlet pipe 2, the second oil inlet pipe 4 is provided with more oil outlets to match the long stroke frying process.
