Description

Technical Field

[0001] The utility model relates to the technical field of oil pressing, in particular to a vegetable oil cold pressing device. Background Art

[0002] Cold pressing of vegetable oil mainly involves extracting oil from oil crops through physical pressing at a lower temperature (usually below 60°C). Compared with traditional hot pressing or solvent extraction, cold pressing can better retain the natural nutrients, color, aroma and bioactive substances in oil crops. Therefore, research on cold pressing technology for various raw materials is becoming more and more extensive, especially for some vegetable oil varieties with high vitamin content. It is particularly important to improve their cold taste and oil extraction rate.

[0003] However, compared with the oil pressing method after frying, the oil yield of the cold pressing method is relatively low and the cost is higher. Therefore, the impact of the oil yield is particularly important in the research process. At the same price, it can improve the efficiency of the enterprise. For this reason, we proposed a vegetable oil cold pressing equipment to solve the above problems. Utility Model Content

[0004] The present application provides a vegetable oil cold pressing device, which solves the problems of low cold pressing oil yield and slow equipment preheating.

[0005] The present application provides a vegetable oil cold pressing equipment, including a cold press, a spiral feed pipe is installed at the feed port of the cold press, a steam pipe connected to the spiral feed pipe is provided on the spiral feed pipe, a discharge pipe is installed at the feed port of the spiral feed pipe, a support frame is installed on the cold press through a support plate, a discharge bin is installed on the support frame, a weighing unit is provided between the discharge bin and the support frame, the discharge bin and the discharge pipe are connected by a connecting hose, a discharge valve is installed between the discharge bin and the connecting hose, and a temperature sensor is installed at the bottom of the oil outlet of the cold press.

[0006] Preferably, the weighing unit includes a weighing sensor installed on the support frame, and the lower hopper is provided with a supporting ear, and the supporting ear is mounted on the weighing sensor.

[0007] Preferably, a protective cover is provided on the cold press.

[0008] Preferably, a material level meter is also installed in the discharge pipe.

[0009] Preferably, a water supply pipe communicating with the spiral feed pipe is further provided on one side of the spiral feed pipe.

[0010] Preferably, the steam pipe and the water supply pipe are both connected to the spiral feed pipe through a connecting hole.

[0011] Preferably, the connecting holes are evenly distributed on the spiral feeding pipe.

[0012] Preferably, the spiral feeding pipe is arranged at an angle.

[0013] Preferably, guide grooves are provided at the bottom of both sides of the protective cover, and drainage grooves are provided at one end of the two guide grooves.

[0014] It can be seen from the above technical solution that the present application provides a vegetable oil cold pressing equipment. When in use, the present application sends the oil to the discharge bin. The discharge valve can be closed during the normal loading process of the discharge bin. After the loading is completed, the weighing unit is measured and then discharged. Before discharging, steam is introduced into the spiral feed pipe through the steam pipe. After the measured values of the temperature sensor are all greater than 70°C, the discharge valve is opened for discharge processing, and the spiral feed pipe is used to feed the material into the cold press. At the same time, the steam pipe introduces saturated water vapor into the spiral feed pipe. The water vapor partially condenses while heating the oil, and enters the cold press together with the oil to press the oil. The amount of saturated steam water injected is 20-35% of the mass of the oil. The calculation method is to calculate the weight once for each batch of material under the discharge valve and observe the amount of water vapor used.

[0016] 1. Through the setting of the discharge pipe, discharge valve and weighing unit, the oil usage, oil pressing efficiency and oil output rate can be obtained, and the working condition of the cold press can be monitored in real time;

[0017] 2. The spiral feed pipe can stably feed the material into the cold press, stabilize the operating power of the cold press, and improve the stability of oil pressing and the stability of the motor;

[0018] 3. Through the setting of steam pipe and temperature sensor, the cold press can be preheated quickly, the fluidity of oil can be improved, and the oil pressing efficiency can be further improved.

[0019] In summary, the present application can stabilize the delivery volume of oil pressing by weighing, and can also stably control the ratio of oil and water to avoid the influence of too much or too little water addition on the oil output. In addition, the application mainly introduces hot steam, which can further preheat the oil, improve the fluidity of the oil, and further increase the oil output. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] See also Figure 1-5, a vegetable oil cold pressing equipment, this application mainly uses the method of adding water and improving the fluidity of oil to increase the oil yield, through the transformation of the cold press, in order to achieve the above purpose, specifically, including a cold press 1, the cold press 1 in this application is not limited, because this application adopts the steam method, so the cold press 1 is provided with a protective cover 2, which can prevent steam from moving in other directions, and specifically, condensate collection structures are provided on both sides of the protective cover 2. The condensate collection structure is located on both sides of the oil roller and does not affect the normal oil output and dripping of the cold press 1. A spiral feed pipe 4 is installed at the feeding port of the cold press 1. In this application, in order to stabilize the feeding, the spiral feed pipe 4 is used for feeding. Setting the spiral feed pipe 4 for feeding can not only stabilize the feeding, but also can adjust the feeding according to the different oil materials. The characteristics before, adjust the feeding amount to achieve the purpose of squeezing different oils. It is worth noting that the addition amount of different oils is not the content protected by this application and will not be disclosed in detail here. The spiral feeding pipe 4 is provided with a steam pipe 3 connected to the spiral feeding pipe 4. It should be understood that the steam pipe 3 of this application is connected to the steam generating device to provide steam. In this application, when the equipment is preset, high-temperature and high-pressure steam can be introduced, which can be preheated with the equipment in a short time. During the feeding process, low-pressure saturated steam is introduced and hot water is added to the oil. In this application, the amount of saturated steam water injected is 20-35% of the mass of the oil. The amount of steam added is controlled according to the ambient temperature. When the indoor temperature is high in summer, the steam amount is reduced so that the steam only achieves the purpose of heating.

[0029] The feeding port of the spiral feeding pipe 4 is equipped with a discharge pipe 8, which is used to temporarily store materials. The oil is first stored in the discharge pipe 8, and the material is stably transported to the spiral feeding pipe 4 through the discharge pipe 8 to avoid material shortage. Specifically, the discharge can be monitored by regularly conveying materials or setting a material level sensor. A support frame 13 is installed on the cold press 1 through the support plate 5. A discharge bin 7 is installed on the support frame 13. A weighing unit is provided between the discharge bin 7 and the support frame 13. The weighing unit is used to weigh the material quality in the discharge bin 7. By monitoring the quality of the oil passing through the discharge bin 7 per unit time, the cold press 1 can be monitored. The oil pressing efficiency is improved, and the steam volume is adjusted. The discharge bin 7 and the discharge pipe 8 are connected by a connecting hose 15. A discharge valve 14 is installed between the discharge bin 7 and the connecting hose 15 to control the discharge of the discharge bin 7. When the discharge bin 7 is loaded, the discharge valve 14 needs to be closed to reduce the measurement error of the weighing unit. A temperature sensor 6 is installed at the bottom of the oil outlet of the cold press 1 to monitor whether the preheating temperature of the cold press 1 reaches the working temperature. It can also monitor whether the water vapor temperature is too high or too low. In the specific monitoring process, the oil outlet temperature needs to be lower than 55 degrees and the preheating temperature needs to reach 75 degrees.

[0030] In the present utility model, the weighing unit includes a weighing sensor 10 installed on a support frame 13, and a supporting ear 12 is installed on the lower hopper 7. The supporting ear 12 is mounted on the weighing sensor 10. Specifically, 3 or 4 weighing sensors 10 can be set at equal intervals. The weighing quality of the oil can be obtained through the central control connection control.

[0031] In some embodiments, in order to further improve the stability of oil discharge, a level meter 11 is also installed in the discharge pipe 8. The level meter 11 is installed in two ways. The first installation method is to install it below the discharge pipe 8. When the material reaches the level meter 11, the discharge valve 14 opens, and the discharge is completed within the set time. It is opened when the material reaches the level meter 11 again. The second method is to install it above the discharge pipe 8. When the material in the discharge pipe 8 reaches the top of the level meter 11, the discharge is closed. After the set time, the discharge valve 14 opens for discharge and waits for the material to be closed again for discharge.

[0032] In some embodiments, a water supply pipe 16 connected to the spiral feed pipe 4 is also provided on one side of the spiral feed pipe 4. When the steam cannot meet the water supply requirements, water supply operation can be performed through the water supply pipe 16. The steam pipe 3 and the water supply pipe 16 are both connected to the spiral feed pipe 4 through the connecting hole 9. The connecting holes 9 are evenly distributed in the spiral feed pipe 4. During the process of transporting oil, water is evenly supplied.

[0033] In some embodiments, the spiral conveying pipe 4 is arranged at an angle, and when the length of the spiral conveying pipe 4 is constant, the length and height after installation can be reduced.

[0034] In some embodiments, guide grooves 21 are provided at the bottom of both sides of the protective cover 2, and a drainage groove 22 is provided at one end of the two guide grooves 21. While the protective cover 2 prevents water vapor from running around, the guide grooves 21 can collect water droplets condensed on the side walls of the protective cover 2 and discharge them through the drainage grooves 22. It is worth noting that the guide grooves 21 and the oil discharge area do not overlap, so no oil will enter the guide grooves 21. The water vapor leaving the cold press 1 condenses in the protective cover 2 and is discharged, which can effectively reduce the mixing of the squeezed oil and water.

[0035] It can be seen from the above technical solution that when the present application is in use, the oil is delivered to the discharge bin 7. The discharge valve 14 can be closed during the normal loading process of the discharge bin 7. After the loading is completed, the weighing unit is measured and then discharged. Before discharging, steam is introduced into the spiral feed pipe 4 through the steam pipe 3. After the measured values of the temperature sensor 6 are all greater than 70°C, the discharge valve 14 is opened for discharge processing, and the spiral feed pipe 4 is used to feed the material into the cold press 1. At the same time, saturated water vapor is introduced into the spiral feed pipe 4 by the steam pipe 3. The water vapor partially condenses while heating the oil, and enters the cold press 1 together with the oil for oil extraction. The amount of saturated steam water injected is 20-35% of the mass of the oil. The calculation method is to calculate the weight once for each batch of material under the discharge valve 14 and observe the amount of water vapor used.
