Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food processing, and particularly relates to an oil feeding device. Background Art
[0002] With the change of consumers' flavor requirements, high-melting-point oils such as lard, chicken oil and peanut oil are more and more widely used in foods and seasonings. As Figure 3 shown, in the processing process, the conventional oil feeding method is that the input end and the output end of a rotor pump 7 are respectively connected with a raw material tank 5 and a reaction tank 15 through a material hose 6, and the oil in the raw material tank 5 is pumped into the reaction tank 15 through the rotor pump 7.
[0003] However, in colder seasons, the physical states of oils such as lard and chicken oil will become thick. It is necessary to pre-heat the raw material tank and the oil in it together in a drying room until it is heated to a fluid state and then pumped into the reaction tank 15.
[0004] For the above feeding process, the following problems exist:
[0005] 1. During the heat drying of the oil in the raw material tank in the drying room, the heat needs to gradually conduct from the outer wall of the raw material tank to the inside of the oil. The heat conduction rate is poor. Therefore, it is necessary to heat dry at a high temperature of 90 - 95 °C for 24 - 48 h to restore the physical state of the oil from outside to inside to a fluid state for subsequent material pumping of the oil. It can be seen that it takes a long time for heat drying and the efficiency is low;
[0006] 2. When the oil is heat dried in the drying room, the temperature is high and the time is long, which easily causes the unsaturated fatty acids in the oil to react with oxygen to generate lower fatty acids, hydroxy acids, esters, aldehydes, etc. These compounds will further decompose into smaller molecules such as aldehydes, ketones, acids, alcohols, etc. These changes not only reduce the quality of the oil (such as darker color, lower smoke point, higher peroxide value), but also produce rancid odors, which have an adverse impact on the nutrition and safety of foods.
[0007] 3. In addition, after the oil pumping is completed, about 30 L of oil will remain in the material hose. It is necessary to manually disassemble the material hose, recover and weigh it, and after supplementing the process loss, manually put the supplemented oil into the reaction tank. Each time it takes about 0.5 h. If 8 tanks of oil are fed at a time, then it takes a total of 4 h to process the residual oil in the pipeline. The processing process is relatively cumbersome and time-consuming. Content of the Utility Model
[0008] The purpose of the utility model is to provide an oil feeding device, which avoids the risk of oil quality deterioration, improves the efficiency and saves costs.
[0009] The purpose of the utility model is achieved by the following technical solutions:
[0010] An oil feeding device, which includes a rotor pump. A material hose for connecting with a raw material tank is arranged at the input end of the rotor pump. It is characterized in that: it further includes a feeding pipe, a heat-conducting oil tracing pipe, an oil pump and a heat-conducting oil tank with a heating function. The feeding pipe is arranged at the output end of the rotor pump and is used for connecting with a reaction tank. The heat-conducting oil tracing pipe is wrapped around the feeding pipe. A liquid channel is formed between the inner wall of the heat-conducting oil tracing pipe and the outer wall of the feeding pipe. A heat-conducting oil return port and a heat-conducting oil input port communicating with the liquid channel are respectively arranged at both ends of the heat-conducting oil tracing pipe. The heat-conducting oil return port, the heat-conducting oil tank, the oil pump and the heat-conducting oil input port are connected in sequence. The heat-conducting oil in the heat-conducting oil tank will be circulated through the liquid channel under the drive of the oil pump.
[0011] During use, the utility model can heat the heat-conducting oil in the heat-conducting oil tank to a set temperature, and then circulate the heat-conducting oil through the liquid channel under the drive of the oil pump, and heat the feeding pipe through the heat-conducting oil, so as to quickly heat the oil entering the feeding pipe to a fluid state and realize continuous feeding.
[0012] On the basis of the above structure, the utility model can further add the following structure: the oil feeding device further includes a purging pipe. An air inlet is arranged at one end of the feeding pipe connected with the output end of the rotor pump. The air outlet end of the purging pipe is connected with the air inlet of the feeding pipe. A ball valve is arranged at the air outlet end of the purging pipe. The air inlet end of the purging pipe is used for connecting with an external air source.
[0013] Further, a filter is arranged at the air inlet end of the purging pipe.
[0014] Further, the filter includes a three-stage filter and a sterile filter.
[0015] Further, a check valve is arranged at the position where the feeding pipe is connected with the output end of the rotor pump, so that the oil can only flow from the rotor pump to the feeding pipe through the check valve.
[0016] Further, the feeding pipe and the heat-conducting oil tracing pipe are hard pipes or flexible hoses. The preferred solution is to select hard pipes.
[0017] Further, the heat-conducting oil return port and the heat-conducting oil tank are connected through a return oil pipe, and the oil pump and the heat-conducting oil input port are connected through an inlet oil pipe.
[0018] Compared with the prior art, the utility model has the following beneficial effects:
[0019] 1. The utility model heats the feeding pipe with heat-conducting oil heated by a heat-conducting oil tank, so that the grease in the feeding pipe can be heated to a fluid state, directly reducing the process of sending the grease into the drying room for hot drying, realizing continuous pumping of the grease, saving the hot drying time (about 24-48 hours each time), improving the efficiency, and reducing the production delivery time of 3 days to 1 day in actual use.
[0020] The utility model conducts heat by the contact of the heat-conducting oil with the outer wall of the feeding pipe, with a large contact area and high heat conduction efficiency. The grease entering the feeding pipe can quickly turn into a fluid state at a temperature of 50-85 °C and within 3-5 seconds, with low energy consumption, thus reducing the cost, and approximately reducing the energy consumption cost by 50 yuan per ton.
[0021] The utility model can reduce the process of sending the grease into the drying room for hot drying, can heat the grease at a lower temperature in a short time, and avoids the quality deterioration risks of the grease such as color and flavor caused by long-term high-temperature placement of the grease.
[0022] 2. The utility model can further add a purge pipe to purge the feeding pipe, and purge the grease remaining in the feeding pipe into the reaction tank. The purge operation can be basically completed within 1 minute, thus eliminating the need for pipeline disassembly, recovery weighing and other work, improving the efficiency, and ensuring the accuracy of the grease input. During the processing, about 4 hours of production processing time can be saved for each batch (8 cans of grease). BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment:
[0033] As Figure 1 shown is the grease feeding device of this embodiment, which includes a rotor pump 7, a material hose 6, a feeding pipe 10, a heat-conducting oil tracing pipe 11, an oil pump 14, a heat-conducting oil tank 13, a purging pipe 3, a three-stage filter 1 and a sterile filter 2.
[0034] A material hose 6 is arranged at the input end of the rotor pump 7, and the material hose 6 is connected to the raw material tank 5 during use. The feeding pipe 10 is arranged at the output end of the rotor pump 7, and the output end of the feeding pipe 10 is connected to the reaction tank 15 during use. A check valve 8 is arranged at the position where the feeding pipe 10 is connected to the output end of the rotor pump 7, and through the check valve 8, the grease can only flow from the rotor pump 7 to the feeding pipe 10.
[0035] As Figure 2 shown, the heat-conducting oil tracing pipe 11 is wrapped around the feeding pipe 10, and the heat-conducting oil tracing pipe 11 basically encloses the feeding pipe 10 inside, and only both ends of the feeding pipe 10 penetrate out from both ends of the heat-conducting oil tracing pipe 11. Both ends of the heat-conducting oil tracing pipe 11 are sealed, and a liquid channel 16 is formed between the inner wall of the heat-conducting oil tracing pipe 11 and the outer wall of the feeding pipe 10, and the liquid channel 16 is used for the circulation of the heat-conducting oil.
[0036] Both ends of the heat-conducting oil tracing pipe 11 are respectively provided with a heat-conducting oil return port 17 and a heat-conducting oil input port 18, and the heat-conducting oil return port 17 and the heat-conducting oil input port 18 are respectively communicated with both ends of the liquid channel 16. Among them, the heat-conducting oil return port 17 is connected to the heat-conducting oil tank 13 through a return oil pipe 9, the outlet of the heat-conducting oil tank 13 is connected to the input end of the oil pump 14, and the output end of the oil pump 14 is connected to the heat-conducting oil input port 18 through an inlet oil pipe 12, so as to connect the heat-conducting oil tank 13, the oil pump 14 and the liquid channel 16 into a circulation channel for heat-conducting oil circulation. Driven by the oil pump 14, the heat-conducting oil in the heat-conducting oil tank 13 will circulate through the liquid channel 16, so as to heat the feeding pipe 10.
[0037] Among them, the heat-conducting oil tank 13 is filled with heat-conducting oil, and the heat-conducting oil tank 13 is provided with a conventional heating device, which has a heating function and can heat the heat-conducting oil therein.
[0038] Both the feeding pipe 10 and the heat-conducting oil tracing pipe 11 in this embodiment are hard pipes. The setting of the hard pipes can make the feeding pipe 10 and the heat-conducting oil tracing pipe 11 better nested together, better ensure that the feeding pipe is in the central position of the heat-conducting oil tracing pipe, and the heating is more uniform.
[0039] In this embodiment, an air inlet 19 is provided at one end of the feeding pipe 10 connected to the output end of the rotor pump 7. The air inlet 19 is located outside the heat-conducting oil tracing pipe 11. The air outlet end of the purging pipe 3 is connected to the air inlet 19 of the feeding pipe 10. A ball valve 4 is provided at the air outlet end of the purging pipe 3 to control the opening and closing of the purging pipe 3. The three-stage filter 1 and the sterile filter 2 are sequentially arranged at the air inlet end of the purging pipe 3. The three-stage filter 1 in this embodiment includes three stages: a coarse filter, a fine filter and an activated carbon filter. During use, the air inlet end of the purging pipe 3 is connected to an external air source, and the air source will provide compressed air. The compressed air first passes through the three-stage filter 1 to filter impurities and moisture, and then passes through the filtration of the sterile filter 2.
[0040] The usage method of the grease feeding device in this embodiment is as follows:
[0041] Before feeding, the output end of the feeding pipe 10 needs to be connected to the reaction tank 15. When feeding is required, first turn on the heat-conducting oil tank 13 and heat the temperature of the heat-conducting oil to 50 - 85 °C. The specific temperature can be set according to the actual usage situation; then start the oil pump 14. The oil pump 14 will extract heat-conducting oil from the heat-conducting oil tank 13. The heat-conducting oil will enter the liquid channel 16 after passing through the inlet oil pipe 12 and the heat-conducting oil input port 18. The heat-conducting oil in the liquid channel 16 will heat the feeding pipe 10. After the heat-conducting oil flows through the liquid channel 16, it will flow back to the heat-conducting oil tank 13 through the heat-conducting oil return port 17 and the return oil pipe 9 to form a cycle. During the process of the heat-conducting oil circulation, the effect of heating the feeding pipe 10 and maintaining a constant temperature is achieved. Among them, the flow rate of the heat-conducting oil flowing through the liquid channel 16 is generally 3 - 7 m / s.
[0042] After circulating and heating with heat-conducting oil for 5 - 10 minutes, insert the material hose 6 into the raw material tank 5 and connect it to the raw material tank 5. Then start the rotor pump 7. The pump speed of the rotor pump 7 is 1 - 3 m / s. The rotor pump 7 will extract grease from the raw material tank 5 and continuously pump the grease into the feeding pipe 10. The grease in the feeding pipe 10 will be heated and become a fluid state, and finally enter the reaction tank 15.
[0043] After completing the pumping of the grease, stop the rotor pump 7. Under the action of the one-way valve 8, the grease in the feeding pipe 10 will not flow back and will stay in the feeding pipe 10. Then open the ball valve 4. The compressed air will first pass through the filtration of the three-stage filter 1 and the sterile filter 2, and then enter the feeding pipe 10 to purge the feeding pipe 10, and purge the remaining grease in the feeding pipe 10 into the reaction tank 15. After completing the purging, close the ball valve 4, and close the heat-conducting oil tank 13 and the oil pump 14.
[0044] The above embodiments of the present utility model do not limit the protection scope of the present utility model. The implementation manners of the present utility model are not limited thereto. All kinds of modifications, substitutions or changes made to the above structure of the present utility model according to the above content of the present utility model, in accordance with the common general technical knowledge and customary means in the art, without departing from the above basic technical idea of the present utility model, shall fall within the protection scope of the present utility model.
