Technical Field
[0001] This utility model relates to the field of roasting machines, specifically an anti-stick roasting machine. Background Technology
[0002] Non-stick pans for stir-frying are a type of cookware and accessories specifically designed for cooking. Their core function is to reduce the sticking of food to the surface of the pan through special materials or technologies. Non-stick pans for stir-frying typically consist of a base pan body, a non-stick coating, and auxiliary structures. They are used in home kitchens, the catering industry, food processing, outdoor cooking, and other scenarios.
[0003] For example, Chinese patent CN208925213U, entitled "A Roasting Machine," includes a cylinder, a motor, rollers, and spiral blades. The cylinder is composed of an inlet section, a middle section, and an outlet section connected sequentially. The inlet section has a feed port at the top, and the outlet section has several discharge ports at the bottom. The middle section is composed of several pipe fittings connected end to end. Each pipe fitting includes an inner wall, an outer wall, and a connecting wall connecting the inner and outer walls. The inner wall, outer wall, and connecting wall form a cavity. Each pipe fitting cavity is equipped with an external power supply. The heating wire is connected to an automatic pressure relief device and a liquid injection pipe on the outer wall opposite to the heating wire, which are connected to the cavity. The roller is rotatably installed in the cylinder and is connected to the main shaft of an external motor. The outer wall of the roller is provided with helical blades along its axial direction. The automatic pressure relief device includes a pressure relief pipe connected to the cavity and a pressure relief valve slidably installed on the pressure relief pipe. The bottom end of the pressure relief pipe is provided with a pressure relief hole. The pressure relief valve moves up and down along the pressure relief pipe under the action of air pressure in the cavity to open or close the pressure relief hole.
[0004] While the existing technology can achieve the stir-frying of roasted goods, in actual use, on the one hand, the roasted goods tend to stick to the cylinder wall. Usually, the sugar in the roasted goods tends to melt when heated, causing the melted roasted goods to stick to the cylinder wall, thus affecting the production quality of the roasted goods. On the other hand, the stir-frying effect of the roasted goods is not good enough. Usually, the roasted goods are only stirred by the internal spiral protrusions, which makes it difficult for the spiral protrusions to turn and stir the roasted goods. Therefore, it does not meet the current needs. In response, we propose an anti-stick pan roasting machine. Utility Model Content
[0005] The purpose of this invention is to provide a non-stick pan roasting machine to solve the problems mentioned in the background art, such as the easy sticking of roasted goods to the cylinder wall and the insufficient stir-frying effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-stick pan roasting machine, comprising a base, a box body fixedly mounted on the upper end of the base, a stir-frying chamber inside the box body, the front end of the stir-frying chamber being an open structure, a stir-frying cylinder inside the stir-frying chamber, the front end of the stir-frying cylinder being an open structure, a sliding groove being provided inside both sides of the box body on the stir-frying chamber, the sliding groove communicating with the stir-frying chamber, a lead screw being provided inside the sliding groove, the lead screw being rotatably connected to the sliding groove, a connecting seat being sleeved at both the front and rear ends of the lead screw, one side of the connecting seat extending into the stir-frying chamber, a fixing ring being fixedly mounted between the connecting seats, and a rotating cavity being provided inside the fixing ring, the rotating cavity being an open structure.
[0007] Preferably, the front and rear ends of the stir-frying cylinder are fixedly provided with limiting rings, which extend into the interior of the rotating cavity and are rotatably engaged with the rotating cavity.
[0008] Preferably, servo motors are fixedly installed on both sides of the rear end of the housing, and the output shaft of the servo motor extends into the interior of the slide groove and is fixedly connected to the lead screw.
[0009] Preferably, a fixing frame is fixedly provided at the rear end of the fixing ring, and a drive motor is fixedly provided at the rear end of the fixing frame. The output shaft of the drive motor extends to the front end of the fixing frame and is fixedly connected to the stir-frying cylinder. A through hole is provided at the center of the rear end of the box, which communicates with the stir-frying cavity, and the drive motor extends to the outside of the box through the through hole.
[0010] Preferably, the inside of the stir-frying cylinder is fixedly provided with several stirring plates, which are distributed in a ring at equal intervals.
[0011] Preferably, a spiral protrusion is fixedly provided on the inner wall of the stir-frying cylinder, and an anti-stick coating is provided on the inner wall of the stir-frying cylinder, the spiral protrusion, and the surface of the stirring plate.
[0012] Preferably, a control panel is fixedly installed at the front end of the housing above the opening of the stir-frying chamber, and the control panel is electrically connected to the servo motor and the drive motor.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model uses a lead screw and a fixed ring to drive the stir-frying cylinder to move back and forth inside the box. When stir-frying the food, the stir-frying cylinder is in a rotating state. At this time, the operator turns on the servo motor through the control panel, so that the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the connecting seat to move slowly and uniformly inside the slide groove. At the same time, the fixed ring, which is fixedly connected to the connecting seat, moves together with the stir-frying cylinder until the stir-frying cylinder is moved to a suitable position. At this time, the rotation direction of the servo motor is changed through the control panel, so that the stir-frying cylinder moves in the opposite direction until the stir-frying cylinder is moved to a suitable position. The above steps are repeated so that the stir-frying cylinder moves back and forth in the stir-frying chamber, thereby preventing the food from sticking to the cylinder wall.
[0015] (2) This utility model can turn the roasted goods inside the stir-frying drum by using a drive motor and a stirring plate. When the roasted goods are being stir-fried, the operator turns on the drive motor through the control panel, so that the output shaft of the drive motor drives the stir-frying drum to rotate. At the same time, the limiting ring on the stir-frying drum rotates inside the fixed ring. During the rotation of the stir-frying drum, the stirring plate inside the stir-frying drum lifts the roasted goods from the bottom of the drum, throws them down and gathers them towards the center of the stir-frying drum, forming a compound motion of ring and longitudinal. This ensures that the roasted goods can fully contact the heat source and avoid uneven heating caused by accumulation. At the same time, the stirring plate can shear and disperse the roasted goods during the rotation process, breaking up any possible lumps or adhesions, thereby improving the stir-frying effect of the roasted goods.
[0016] (3) This utility model can reduce the adhesion of raw materials to the cylinder wall through the anti-stick coating. The anti-stick coating can prevent sticky substances such as sugar and starch from adhering, and can prevent roasted goods from sticking to the inner wall when stir-frying at high temperature. It can also prevent the raw materials from sticking due to sugar and oil seepage or softening due to heat. At the same time, the anti-stick coating can reduce the loss caused by sticking and avoid the need to stop the machine for cleaning due to the sticking of roasted goods, thereby improving the efficiency of roasted goods production.
