Description

Technical Field

[0001] The invention relates to the technical field of ancient tea oil pressing, and in particular to an automatic tea oil pressing device and a pressing method. Background Art

[0002] Tea oil is the common name for camellia oil, also known as camellia oil and camellia seed oil. It is a pure natural high-grade edible vegetable oil extracted from the mature seeds of common camellia (Camellia oleifera Abel) of the Theaceae family Camellia genus. At present, there are roughly two methods for pressing tea oil. One is industrial pressing, which uses automated equipment for oil pressing. It has a high degree of automation and high efficiency. Raw tea powder can be directly heated and pressed, or cooked tea powder can be cold pressed. For example, the Chinese invention patent with publication number CN114381332A discloses a tea oil pressing device and a pressing method for improving the recovery rate of oil vapor, which belongs to the field of tea oil processing technology, including a press body composed of a box body, a box door, a support leg and a stable seat, and also includes: an oil vapor collection mechanism, the oil vapor collection mechanism is provided Placed on the top of the box, to realize the collection of oil vapor; oil-gas-liquid separator, the oil-gas-liquid separator is fixedly connected to the right end of the box, to realize the separation of oil, gas and water, and the oil vapor collection mechanism is connected to the oil-gas-liquid separator to realize the transmission of oil vapor; first oil leakage hole, the first oil leakage hole is provided with multiple; there is also an ancient method of pressing tea oil, which has a low degree of automation, but in the ancient pressing, straw and tea cakes are used to make cakes and press, such tea oil will have the natural aroma of straw, which is obviously different from industrial pressing, so the tea oil pressed by the ancient method is irreplaceable in the market, but the production of tea oil pressed by the ancient method has the following defects:

[0003] Many processes of the traditional method of pressing tea oil require manual operation, and the degree of automation is low. The main steps are grinding, steaming, making cakes with straw and pressing out oil. Among them, grinding, steaming and pressing out oil can all be automated with existing equipment, but making cakes with straw is difficult to automate. It is necessary to manually put the straw in the mold and pour the tea powder in. The edge of the straw will stand up due to the pressure of the tea powder, but it will tilt outward. If the tea powder is directly pressed in this way, the straw on the edge will not be able to cover the surface of the tea powder. It is necessary to manually pull the straw inward by hand and then press it, and remove both hands at the right time, which makes it difficult to automate. In addition, when the tea cake is pressed again, the tea powder oil at the edge is easy to squeeze out, and the oil in the middle of the tea cake is easy to fill into the tea powder at the edge after being squeezed out, which is difficult to squeeze out, resulting in incomplete oil extraction and loss.

Example 3

[0050] See also Figure 1-11, which is the third embodiment of the present invention, and is based on the above two embodiments, a pressing method of a tea oil automatic pressing device, comprising the following steps:

[0051] Step 1: Grinding: Dry the tea seeds, peel them and add them into an automated grinding device to grind them into powder to obtain tea seed powder;

[0052] Step 2: Steaming: Steam the tea seed powder obtained in step 1 for half an hour to obtain tea powder, and pour the tea powder into the hopper 143 in the feeding structure 14;

[0053] Step 3: Making cakes: Spread dry rice straw on the top surface of the mold shell 131, then the linear sliding assembly 12 sends the die structure 13 to the position of the material discharge structure 14, then the pressing block 148 presses down to press the middle of the dry rice straw into the mold cavity 132, then the tea powder is added into the mold cavity 132 through the pushing auger 1413, then the pressing block 148 returns to its position, the linear sliding assembly 12 sends the die structure 13 to the position of the cake pressing structure 15, then the four arc strips 134 move inwards. The template 154 is moved so that the dry straw at the edge is tilted toward the center of the mold cavity 132. Then the template 154 is pressed down. Under the action of the spiral groove 155, the template 154 will rotate slightly, so that when it contacts the top of the dry straw, it can generate a torsion force on the dry straw. Then, the template 154 is pressed down so that the dry straw crosses each other. When the template 154 continues to be pressed down into the mold cavity 132, the four arc-shaped strips 134 return to their positions, and the template 154 continues to be pressed down to press the tea powder into a tea cake.

[0054] Step 4: Oil extraction: put the tea cake obtained in step 3 between multiple pressing components 26, then start the second oil cylinder 27 to push the force plate 28 to move, apply pressure to the multiple pressing components 26, and maintain it for fifteen minutes after reaching the maximum pressure.

The squeezed oil falls into the oil guide groove 222 and flows into the oil bin 220, and tea oil is obtained in the oil bin 220. Example 4

[0055] See also Figure 1-11, which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments. When the present invention is used, the tea seeds are dried and shelled and added to the automatic grinding equipment to be ground into powder to obtain tea seed powder; the tea seed powder is steamed for half an hour to obtain tea powder, and the tea powder is poured into the hopper 143 in the feeding structure 14; dry rice straw is spread on the top surface of the mold shell 131, and then the linear sliding component 12 sends the pressing mold structure 13 to the position of the feeding structure 14, and then the pressing block 148 is pressed down to press the middle part of the dry rice straw into the mold cavity 132, and then the tea powder is added to the mold cavity 132 through the pushing auger 1413 The pressing block 148 returns to its original position, and the linear sliding assembly 12 sends the pressing mold structure 13 to the position of the cake pressing structure 15. Then, the four arc-shaped strips 134 move inward, so that the dry straw at the edge tilts toward the center of the mold cavity 132. Then, the template 154 is pressed down. Under the action of the spiral groove 155, the template 154 will rotate slightly, so that when it contacts the top of the dry straw, it can generate a torsion force on the dry straw, and then cooperate with the downward pressure to make the dry straw cross each other. When the template 154 continues to be pressed down into the mold cavity 132, the four arc-shaped strips 134 return to their original positions, and the template 154 continues to be pressed down. The tea cake is placed between the plurality of pressing components 26, and then the second oil cylinder 27 is started to push the force plate 28 to move, and pressure is applied to the plurality of pressing components 26. After reaching the maximum pressure, it is maintained for fifteen minutes, and then the high-pressure air pump 218 is started, the valve 219 is opened, and the air cavity 263 is inflated. The diaphragm 264 is used to apply pressure to the middle of the tea cake for fifteen minutes, and the squeezed oil falls into the oil guide groove 222 and flows into the oil bin 220, and tea oil is obtained in the oil bin 220. The present invention adopts the mold shell 131 to load straw and tea powder for cake making When making cakes, the four arc-shaped strips 134 can push the straw inward, so that the straw originally inclined outward can be inclined inward, replacing the method of gathering the straw by hand. After that, when the template 154 is pressed down again, the straw can be pressed on the surface of the tea powder. Automation is achieved under the premise of adopting the ancient method of oil pressing of making cakes with straw. In the present invention, the oil pressing mechanism 2 presses the tea cake to press the oil through the pressing component 26, and a diaphragm sheet 264 is provided for the middle part of the tea cake, and the pressure in the middle part of the tea cake is further increased by air pressure, so that more oil in the middle part of the tea cake is squeezed out, reducing the loss.
