Description

Technical Field

[0001] The present invention relates to the field of oil extraction equipment, and in particular to a stir-frying machine for rapeseed oil processing. Background Art

[0002] A vertical steaming and frying pan is a layered steaming and frying equipment formed by stacking several single steaming and frying pans up and down. Its specific process is to wet and heat the green billets made by an oilseed rolling machine to turn them into cooked billets. The function of heating and stir-frying is to further destroy the oilseed cell tissue or change the internal structure of the oilseed by means of the action of moisture and temperature, which is more conducive to extracting the oil in the cell tissue and increasing the oil yield. At the same time, the chemical changes occurring during the stir-frying process are also conducive to improving the quality of the oil.

[0003] The vertical steaming and frying pan is formed by stacking multiple layers of pot bodies. Rapeseed enters from the top and falls layer by layer. Each layer realizes the wet heat treatment through steam heating and mechanical stirring. The specific process can generally be divided into two stages. One is the steaming stage, which occurs in the upper layer of the steaming and frying pan. In this stage, the moisture of the material embryo is increased by steam or water, and the rapeseed is softened and the protein is denatured by steam heating.

[0004] The other stage is the stir-frying stage, which still heats the material embryo with steam as the medium and reduces the moisture of the material embryo.

[0005] Currently, the following problems exist;

[0006] Due to the different processes to be carried out at different levels, the humidity and temperature of the steam are also different in a specific level. However, in the specific steaming and stir-frying process, due to the differences in the material embryos, the residence time in the specific processing stage is also different. Once the material embryo is transferred from this layer to another layer during the processing, except for forcibly stopping the operation of the equipment, it is impossible to return the material embryo in the equipment to the previous stage for continuous processing. This means that when processing different material embryos, once the residence time of the material embryo in a certain level is insufficient, it will lead to the failure of the entire batch of material embryos in processing.

[0027] In the following description, many specific details are set forth to fully understand the present invention.

Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0029] Furthermore, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment from other embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1 to 8 , this embodiment provides a rapeseed oil processing steaming and frying machine, including a steaming and frying pot 100. The steaming and frying pot 100 is integrally a hollow cylinder. A plurality of groups of partitions 101 are arranged inside the steaming and frying pot 100. An air inlet pipe 102 and an air outlet pipe 103 are connected to each group of partitions 101; a frying mechanism 200, the frying mechanism 200 includes a second driving device 201. The second driving device 201 is fixed to the bottom of the outer wall of the partition 101. The output end of the second driving device 201 is connected to a central roller 202. The central roller 202 is hollow inside. A plurality of groups of frying blades 203 are fixedly connected to the outer wall of the central roller 202. A valve block 204 is movably connected to the outer wall of the frying blade 203; a reflux mechanism 300, the reflux mechanism 300 includes a third driving device 301. The third driving device 301 is fixedly connected to the top of the steaming and frying pot 100. The output end of the third driving device 301 is connected to a screw rod 302. The screw rod 302 is rotatably connected inside the central roller 202.

[0032] The number of groups of the stir-frying blades 203 is the same as that of the partition layers 101. There are two partition layers 101 in each group. Second valve openings 202a are provided on the outer wall of the central roller 202 at the positions of the stir-frying blades 203, and the second valve openings 202a are blocked by valve blocks 204. The stir-frying blades 203 have a certain inclination angle. During the normal steaming and frying process, the second driving device 201 drives the central roller 202 and the stir-frying blades 203 to rotate. The stir-frying blades 203 rotate inside the partition layer 101 to stir-fry and agitate the material embryos inside the partition layer 101, so as to make the processing of the material embryos more uniform. In this state, the valve block 204 always blocks the second valve opening 202a. When the second driving device 201 starts to reverse, the valve block 204 at the level of the material embryo to be refluxed and the target level is separated from the second valve opening 202a through the control of the fourth driving device. Due to the certain inclination angle of the stir-frying blades 203, the material embryos to be refluxed are collected by the rotating stir-frying blades 203 and fall into the central roller 202, and are transported upward by the rotation of the screw rod 302 and overflow through the second valve opening 202a at the target level. Therefore, the specified reflux of the material embryos from bottom to top is completed for reprocessing, so as to handle the failure of the material embryo processing caused by the insufficient residence time of different material embryos at their respective levels.

[0033] A first valve opening 101a is provided at the bottom of each group of partition layers 101. A treatment box 106 is arranged outside the steaming and frying pan 100. A first driving device 106a is installed inside the treatment box 106. The output end of the first driving device 106a is connected with a valve 106b, and the valve 106b is rotatably connected to the first valve opening 101a. When the material embryos inside the first valve opening 101a need to be lowered to the next level, the first driving device 106a controls the valve 106b to rotate at the first valve opening 101a, so that the first valve opening 101a at this level is in an open state, so that the material embryos at this level are lowered to the next level.

[0034] Chute grooves are provided on the outer wall of the stir-frying blades 203. A fourth driving device is arranged inside the valve block 204. The valve block 204 is slidably connected to the outer wall of the stir-frying blades 203. The sliding range of the valve block 204 is from the second valve opening 202a to the inner wall of the steaming and frying pan 100. The opening and closing of the second valve opening 202a are controlled by the sliding of the valve block 204. In this embodiment, the specific structures of the stir-frying blades 203 and the valve block 204 are as follows: Two groups of chute grooves are penetrated through the outer wall of the stir-frying blades 203, and internal gear teeth are arranged in both groups of chute grooves. The valve block 204 is divided into two parts and is connected by a driving shaft. The driving shaft is matched with the output end of the fourth driving device. A gear is arranged in the middle of the driving shaft. The fourth driving device drives the driving shaft and the gear to rotate inside the chute groove, and then drives the valve block 204 to slide on the outer wall of the stir-frying blades 203.

[0035] Several groups of outlet pipes 103 are all connected to the main pipe through branch pipes, while several groups of inlet pipes 102 are independent of each other. The independent inlet pipes 102 enable more accurate temperature and humidity control at the corresponding levels.

[0036] The top of the cooking and steaming kettle 100 is provided with a feed inlet 104, and the bottom of the outer wall of the cooking and steaming kettle 100 is provided with a discharge outlet 105.

[0037] Furthermore, in the first driving device, the second driving device, the third driving device, and the fourth driving device in this embodiment are all servo motors.
