Description

Technical Field

[0001] This utility model relates to the field of oil pressing equipment technology, specifically to a roasting mechanism for a small automatic oil press. Background Technology

[0002] Existing small-scale commercial automatic oil presses are all equipped with automatic roasting mechanisms to roast the raw materials before pressing, thereby increasing the oil yield. However, the roasting process generates smoke and moisture, which need to be removed to prevent pollution of the working environment. Current practices typically involve installing the roasting pan inside a box-type frame of the equipment, with an open top. An exhaust hood is installed above the pan, connected to an exhaust pipe and a fan, which actively exhausts the fumes and moisture outdoors. However, due to environmental protection requirements, the exhaust pipe is quite long and usually needs to extend to the roof. This not only increases the energy consumption of the fan but also affects the smoke extraction efficiency. If the smoke and moisture cannot be removed in time, the temperature around the roasting pan will rise rapidly, which will affect the stability of the control system mounted on the box-type frame and create safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide an improved stir-frying mechanism to improve smoke extraction and achieve better stir-frying results.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A roasting mechanism for a small automatic oil press includes a closed housing with an installation cavity inside. The housing has an air inlet for external air intake, which can be opened or closed to regulate airflow within the housing. A roasting pot is housed within the installation cavity, with a gap between the roasting pot and the inner wall of the housing. This gap reduces heat transfer from the roasting pot to the outside of the housing and creates a negative pressure space. A lid is provided on top of the roasting pot, and the lid and the roasting pot are connected in a non-sealed manner, allowing gas flow. An air outlet pipe connects to the lid or the roasting pot, passing through... The housing extends to the outside of the housing, and the outer wall of the exhaust pipe is sealed to the housing to guide the moisture and smoke in the frying pan to the outside of the housing. The housing is equipped with an exhaust device to exhaust the heat and gas inside the housing. When the air inlet is closed and the exhaust device is running, the gap space is under negative pressure through the exhaust device, preventing the moisture and smoke in the frying pan from being discharged from the exhaust pipe. When the air inlet is open, the housing forms an airflow channel with the exhaust pipe through the air inlet, and the exhaust pipe discharges the moisture and smoke in the frying pan to the outside of the housing through the chimney effect.

[0006] In a preferred embodiment, the air inlet is an openable and closable door located on the housing.

[0007] In a preferred embodiment, the door is equipped with an automatic opening device, which includes a motor drive structure. The motor drive structure is used to drive the door to open after the stir-frying time has reached a set time, so as to release the water vapor and smoke in the stir-frying pot.

[0008] In a preferred embodiment, a heat insulation layer is provided between the inner and outer surfaces of the stir-fry pot and the pot lid to reduce heat dissipation.

[0009] In a preferred embodiment, the air outlet duct is vertically positioned at the rear end of the outer casing to enhance the airflow guiding capability of the chimney effect.

[0010] In a preferred embodiment, the exhaust device is an electric exhaust fan installed on the side wall of the box, the air volume and speed of which are adjustable, and is used to adjust the airflow state inside and outside the box according to the roasting stage.

[0011] The beneficial effects of this invention are as follows: During the stir-frying process, the air inlet can be closed and the exhaust device turned on, creating a negative pressure state inside the chamber. This prevents moisture from escaping through the exhaust pipe. Combined with the lid, the chamber forms a closed space, resulting in a steaming effect on the dough. Compared to existing stir-frying mechanisms, this steaming method allows the dough to reach the desired doneness in a shorter time, and the dough is heated more evenly. This not only increases the oil yield but also minimizes heat loss, shortens the stir-frying time, and is more energy-efficient. After a certain steaming time, the air inlet is opened to release the negative pressure. At this point, airflow enters the chamber through the air inlet and flows out... The lid enters the roasting pot and then the exhaust duct, creating a chimney effect that quickly exhausts the moisture and smoke inside the roasting pot to the outside. This not only ensures that the raw material meets the required dryness for pressing, but also eliminates the need for a fan to exhaust smoke and moisture compared to existing technologies. The chimney effect of the exhaust duct effectively increases the exhaust speed, and the higher the exhaust duct outlet, the faster the exhaust speed. In addition, the roasting pot is sealed by a lid, and there is a gap between the lid and the inner wall of the box. The heat inside the roasting pot is not easily conducted to the box and affects the control system. When the exhaust device is on, the heat in the gap can also be discharged in time, thereby eliminating safety hazards. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] Figure 1 This is a schematic diagram of the overall structure of the stir-frying mechanism in the embodiment. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] This embodiment uses the roasting mechanism of a small automatic oil press as an example for illustration. (Refer to...) Figure 1 The internal structure of the frying mechanism can be seen. The schematic diagram of the frying mechanism is a simplified diagram. In the actual equipment, the top of the box 1 is usually equipped with a feeding hopper, which extends into the box 1 and is connected to the frying pot 4. The feeding port of the hopper is equipped with an openable and closable baffle. The bottom of the frying pot 4 is connected to the screw pressing device, and there is also an openable and closable baffle between the frying pot 4 and the screw pressing device. The stir-frying mechanism includes a closed housing 1, with an installation cavity 100 inside. A control panel 2 for the loading control system is located on the outer wall of the housing 1. An air inlet 3 for external air intake is provided on the housing 1, and the air inlet 3 can be opened or closed to regulate airflow within the housing 1. A stir-frying pot 4 is installed within the installation cavity 100, and a gap space is formed between the stir-frying pot 4 and the inner wall of the housing 1. This gap space is used to reduce heat transfer from the stir-frying pot 4 to the outside of the housing 1 and to create a negative pressure space. A lid 5 is provided on the top of the stir-frying pot 4, and the lid 5 is connected to the stir-frying pot 4 via a non-sealed connection that allows gas flow. An exhaust pipe 6 is connected to the lid 5 or the stir-frying pot 4. The air outlet duct 6 passes through the housing 1 and extends to the outside of the housing 1, and the outer peripheral wall of the air outlet duct 6 is sealed to the housing 1 to guide the water vapor and smoke in the stir-fry pot 4 to the outside of the housing 1. The housing 1 is provided with an exhaust device 7 to exhaust the heat and gas in the housing 1. When the air inlet 3 is closed and the exhaust device 7 is running, the gap space is formed by the exhaust device 7 to form a negative pressure state, so that the water vapor and smoke in the stir-fry pot 4 cannot be discharged from the air outlet duct 6. When the air inlet 3 is open, the housing 1 forms an air flow channel with the air inlet 3 and the air outlet duct 6, and the air outlet duct 6 exhausts the water vapor and smoke in the stir-fry pot 4 to the outside of the housing 1 through the chimney effect.

[0016] During the stir-frying process, the air inlet 3 can be closed and the exhaust device 7 turned on to create a negative pressure state inside the housing 1. Since the lid 5 and the stir-frying pot 4 are not sealed, this negative pressure state will affect the air pressure inside the stir-frying pot 4, making its internal air pressure less than or equal to the air pressure at the outlet of the air outlet pipe 6. The water vapor inside the stir-frying pot 4 cannot be discharged from the air outlet pipe 6. In addition, the lid 5 makes the stir-frying pot 4 a closed space, and the raw material is stir-fried in the stir-frying pot 4 in a simmering effect. Compared with the existing stir-frying mechanism, the raw material can be stir-fried to the required degree of doneness in a shorter time, and the raw material is heated more evenly. This not only improves the oil yield of the raw material, but also reduces heat loss, shortens the stir-frying time, and is more energy-efficient. After stir-frying for a certain period of time, the air inlet 3 is opened to release the negative pressure. At this time, the airflow enters the box 1 through the air inlet 3 and enters the roasting pot 4 through the lid 5 to the air outlet 6, forming a chimney effect to quickly discharge the water vapor and smoke in the roasting pot 4 to the outside. This not only ensures that the raw material meets the required dryness for pressing, but also eliminates the need for a fan to discharge smoke and water vapor compared to existing technologies. The chimney effect of the air outlet 6 can effectively increase the exhaust speed, and the higher the outlet of the air outlet 6, the faster the exhaust speed. In addition, the roasting pot 4 is closed by the lid 5 and there is a gap between it and the inner wall of the box 1, so the heat in the roasting pot 4 is not easily conducted to the box 1 and affects the control system. When the exhaust device 7 is turned on, the heat in the gap space can also be discharged in time, thereby eliminating safety hazards.

[0017] In a preferred embodiment, the air inlet 3 is an openable and closable door disposed on the housing 1. The door can be used not only to open and remove raw materials from the frying pan 4, but also as the air inlet 3, thus simplifying the structure. In other embodiments, the air inlet 3 can also be a through hole disposed on the wall of the housing 1, and a valve structure for opening and closing the through hole, etc.

[0018] Furthermore, the door in this embodiment is equipped with an automatic opening device 31, which includes a motor drive structure. This motor drive structure drives the door to open after the stir-frying time has reached a set duration, thereby releasing moisture and smoke from the stir-frying pot 4. The motor drive structure can employ existing technologies such as a gear transmission structure or a lead screw transmission structure driven by a motor. With the automatic opening device 31 installed, the control system can control the motor drive structure to open the door at a set time, completing the automated operation from stir-frying to venting, further improving the level of automation.

[0019] In a preferred embodiment, a heat insulation layer (41, 51) is provided between the inner and outer surfaces of the stir-fry pot 4 and the pot lid 5 to reduce heat dissipation. The heat insulation layer (41, 51) can further reduce heat loss inside the stir-fry pot 4 and lower the temperature of the gap space, thereby further improving safety.

[0020] In a preferred embodiment, the air outlet duct 6 is vertically positioned at the tail end 61 outside the housing 1 to enhance the airflow guiding capability of the chimney effect.

[0021] In a preferred embodiment, the exhaust device 7 is an electric exhaust fan installed on the side wall of the box 1, with adjustable air volume and speed, used to adjust the airflow state inside and outside the box 1 according to the stir-frying stage.

[0022] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
