Technical Field
[0001] The utility model relates to the field of food processing machinery and equipment, and more specifically, to an electric heating roller for frying and baking food. Background Art
[0002] Most electric heating rollers on the market are generally stainless steel tubes with smooth surfaces. During the baking process, the contact point between the stainless steel roller and the food is relatively fixed, which is prone to problems such as partial burning or only partially cooked. In addition, due to the good thermal and electrical conductivity of stainless steel tubes, not only is the heat preservation effect poor, but there are also safety hazards such as leakage, especially when the food is brushed with oil or drips grease during baking. If leakage occurs, it will cause major safety accidents such as fire. In addition, grease and condiments (such as salt, cumin, chili powder, etc.) are usually added to the food during baking. During the baking process, they will adhere to the roller. On the one hand, it will cause the outer surface of the roller to be dirty or even rusty, posing a food safety risk and affecting consumers' desire to buy. On the other hand, grease will drip everywhere, which is not easy to collect and treat. Not only will it affect hygiene, but the sludge formed will also clog the rotating structures such as the roller, thereby affecting the service life of the equipment. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0034] Most electric heating rollers on the market are generally stainless steel tubes with smooth surfaces. During the baking process, the contact point between the stainless steel roller and the food is relatively fixed, which is prone to problems such as partial burning or only partially cooked. In addition, due to the good thermal and electrical conductivity of stainless steel tubes, not only is the heat preservation effect poor, but there are also safety hazards such as leakage, especially when the food is brushed with oil or drips grease during baking. If leakage occurs, it will cause major safety accidents such as fire. In addition, grease and condiments (such as salt, cumin, chili powder, etc.) are usually added to the food during baking. During the baking process, they will adhere to the roller. On the one hand, it will cause the outer surface of the roller to be dirty or even rusty, posing a food safety risk and affecting consumers' desire to buy. On the other hand, grease will drip everywhere, which is not easy to collect and treat. Not only will it affect hygiene, but the sludge formed will also clog the rotating structures such as the roller, thereby affecting the service life of the equipment.
[0035] Aiming at the defects of the prior art, the utility model provides an electric heating roller for frying and baking food processing, Figure 1-5 As shown, the electric heating drum comprises a rotating shaft 1, a heating tube 2 and a ceramic tube 3 which are sleeved in sequence. The outer wall surface of the ceramic tube 3 is the contact surface between the electric heating drum and the food.
[0036] At least one oil guide groove 31 is provided on the outer wall of the ceramic tube 3. The oil guide groove 31 is a single-path structure. The grease on the food and the grease seeped out during baking can drip into the oil guide groove 31, flow smoothly in the oil guide groove 31, and be discharged from both ends of the oil guide groove 31.
[0037] The parts of the ceramic tube 3 near the ends of the oil guide groove 31 include drainage grooves 32 formed by being concave in the radial direction of the ceramic tube 3. The oil guide grooves 31 and the drainage grooves 32 are connected. The grease enters the drainage grooves 32 through the oil guide grooves 31, drips naturally at the drainage grooves 32, and is smoothly received by the collection container arranged below the drainage grooves 32. For the convenience of description, it can be regarded that the ceramic tube 3 is divided into a heating section 301 and a drainage section 302. The heating section 301 is used to contact and heat the food, the oil guide groove 31 is arranged on the heating section 301, the drainage section 302 is used to draw the waste oil into the collection container, and the drainage groove 32 is arranged in the drainage section 302.
[0038] The inner diameter of the ceramic tube 3 (including the drainage groove 32) is equal to the outer diameter of the heating tube 2, the inner diameter of the heating tube 2 is equal to the outer diameter of the rotating shaft 1, the heating tube 2 is sleeved on the rotating shaft 1, the ceramic tube 3 is sleeved on the heating tube 2, the heating tube 2 is located in the heating section 301 of the ceramic tube 3, and the ceramic tube 3 rotates with the rotation of the rotating shaft 1. The ceramic tube 3 is made of non-conductive, rust-free, and easy-to-clean ceramic material to avoid the risk of leakage, and is convenient for cleaning, avoiding the accumulation of oil and seasonings, and is cleaner and more hygienic; the selected ceramic tube 3 has passed the food safety test and can meet the food grade requirements.
[0039] The oil guide groove 31 includes a first oil guide portion 311 and a second oil guide portion 312 formed by extending the two ends of the first oil guide portion 311 toward the end of the ceramic tube 3. The first oil guide portion 311 is connected to the second oil guide portion 312. The first oil guide portion 311 is located in the middle part of the ceramic tube 3 and extends along the axial direction of the ceramic tube 3. The second oil guide portion 312 is an arc-shaped structure, which can better guide the flow of oil during the rotation of the electric heating drum.
[0040] The bending directions of the two second oil guide portions 312 at both ends of the first oil guide portion 311 are opposite, that is, the second oil guide portion 312 on one side is bent in the clockwise direction, and the second oil guide portion 312 on the other side is bent in the counterclockwise direction, and the oil guide groove 31 forms a structure shaped like "∫". This specific structure can use the centrifugal force during the rotation of the electric heating drum to guide the oil to the drainage groove 32 in a directional manner, thereby preventing the oil from accumulating in the oil guide groove 31. In addition, since the oil guide groove 31 is a single-path curved structure, and the connection between the first oil guide portion 311 and the second oil guide portion 312 is smoothly transitioned, the problem that the existing oil guide grooves are crisscrossed and there are multiple intersections and oil is easily accumulated at the intersections can be effectively avoided.
[0041] In a specific embodiment, the depth of the oil guide groove 31 gradually increases from the first oil guide portion 311 to the second oil guide portion 312, which is equivalent to forming a certain slope, and there is a smooth transition between the first oil guide portion 311 and the second oil guide portion 312, which can make it easier for the oil to flow into the drainage groove 32 along the path of the oil guide groove 31, and after entering the drainage groove 32, it will drip and be collected by the collection container.
[0042] Specifically, Figure 1 As shown, the first oil guide portion 311 corresponds to the position A ( Figure 1 The depth of the midpoint dash line is the midline of the ceramic tube 3 in the radial direction) is the minimum depth of the oil guide groove 31, and the depth of the connecting end B between the second oil guide portion 312 and the drainage groove 32 is the maximum depth of the oil guide groove 31. In order to allow oil to enter the drainage groove 32, the depth of the drainage groove 32 is designed to be greater than the maximum depth of the oil guide groove 31.
[0043] Furthermore, in a specific example, the second oil guide portion 312 is connected to the drainage groove 32 via a drainage slope 33, such as Figure 3 As shown, the drainage slope 33 is inclined from one end of the second oil guide portion 312 away from the first oil guide portion 311 toward the drainage groove 32, so as to connect the second oil guide portion 312 and the drainage groove 32, so that the oil can smoothly flow into the drainage groove 32. Furthermore, the drainage slope 33 can be designed as an integral structure surrounding the drainage groove, so as to avoid dead corners where oil is easily accumulated.
[0044] In one embodiment, Figure 1 As shown, the connection between the first oil guide portion 311 and the second oil guide portion 312 includes a transition structure 313, and the transition structure 313 is a smooth arc structure for connecting the first oil guide portion 311 and the second oil guide portion 312 to avoid the accumulation of oil at the connection between the first oil guide portion 311 and the second oil guide portion 312, thereby ensuring the hygiene and safety of food.
[0045] In a specific embodiment, Figure 5 As shown, the groove wall of the oil guide groove 31 and the outer wall of the ceramic tube 3 are connected by a transition arc surface 310, and the transition arc surface 310 can guide the grease dripping on the surface of the ceramic tube 3 into the oil guide groove 31. In addition, the setting of the transition arc surface 310 can make the outer wall of the ceramic tube 3 smoother, avoid bumping against the food, and ensure the integrity of the food. Correspondingly, the groove wall and the groove bottom of the oil guide groove 31 are also connected by a transition arc surface 310 to avoid leaving dead corners and causing the accumulation of oil stains.
[0046] In one embodiment, the surface of the ceramic tube 3 is provided with a glaze layer, which makes the ceramic tube 3 stronger and more wear-resistant, thus having a longer service life. More importantly, the ceramic tube 3 has fast heat transfer and good heat preservation effect, so that food can be baked faster. In addition, the ceramic tube 3 has good high temperature resistance and will not crack even if used for a long time at high temperature, thus ensuring the service life of the equipment.
[0047] In a specific example, if Figure 1 , 2As shown in Figures 4 and 5, the electric heating drum for frying and baking food processing further comprises oil deflector rings 4 arranged at both ends of the ceramic tube 3. The oil deflector rings 4 are cylindrical boss structures. The inner diameter of the oil deflector rings 4 is equal to the outer diameter of the rotating shaft 1, and the oil deflector rings 4 are sleeved on the rotating shaft 1. The outer diameter of the oil deflector rings 4 is larger than the outer diameter of the ceramic tube 3 to prevent oil from entering the ceramic tube 3 or the transmission device, thereby affecting the service life of the equipment.
[0048] Furthermore, the oil retaining ring 4 includes a sealing portion 41, a first oil retaining portion 42, and a second oil retaining portion 43 arranged in sequence along the axial direction. The outer diameter of the sealing portion 41 is equal to the inner diameter of the drainage section 302 of the ceramic tube 3, and is plug-connected with the drainage section 302 of the ceramic tube 3, fixed to the end of the ceramic tube 3, and is used to seal the internal environment of the ceramic tube 3, seal the heating tube 2 in the ceramic tube 3, prevent oil from entering the interior of the ceramic tube 3, ensure the normal use of the heating tube 2, and improve safety performance.
[0049] The outer diameter of the first oil baffle portion 42 is not less than the outer diameter of the ceramic tube 3, and the outer diameter of the second oil baffle portion 43 is larger than the outer diameter of the first oil baffle portion 42, which can ensure that the oil is collected by the collection container according to the set path, avoid oil from seeping from the end of the rotating shaft 1 to pollute the transmission device, and ensure the stable operation and service life of the equipment.
[0050] In a specific embodiment, from Figure 5 It can be seen that the width of the oil guide groove 31 gradually narrows from the side close to the outer wall of the ceramic tube 3 to the bottom of the groove, forming an inclined groove wall, which is more conducive to the collection of oil in the oil guide groove 31.
[0051] In this embodiment, four oil guide grooves 31 are provided on the outer wall of the ceramic tube 3. The four oil guide grooves 31 are evenly arranged on the outer wall of the ceramic tube 3 with the axis of the ceramic tube 3 as the center. The oil guide grooves 31 do not intersect with each other to avoid the dead corners formed by the intersection of the oil guide grooves to accumulate oil. In other embodiments, the number of oil guide grooves 31 can also be reasonably designed according to needs.
[0052] The electric heating drum for frying and baking food processing provided by the embodiment of the utility model has an oil guide groove with a single path structure, which can guide the oil generated in the process of baking food to a specific position for collection and unified treatment, thereby avoiding the problem of oil accumulation at the intersection of the common oil guide grooves, and avoiding the problem of oil spilling everywhere and entering the inside of the electric heating drum to the greatest extent. The centrifugal force during the rotation of the electric heating drum is used to guide the oil in a direction, without accumulation in the electric heating drum, thereby ensuring the service life and cleanliness of the equipment.
[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
