Abstract
Description

[0002] Edible vegetable oil filling equipment is one of the core equipment in the food processing industry. It is mainly composed of oil storage tanks, delivery pipelines, filling heads, bottle positioning mechanisms and control systems. Its function is to achieve accurate and quantitative filling of vegetable oil.
[0003] However, the existing equipment has exposed serious cleaning and maintenance defects in long-term use, the specific defects are as follows: Firstly, the filling heads and pipelines are mostly fixed by welding or bolts, which not only require special tools for disassembly and are time-consuming, but also cause thread wear and seal aging due to frequent disassembly and assembly. Secondly, traditional one-way high-pressure flushing can only remove surface oil stains, but is not efficient for cleaning highly viscous oils such as palm oil. Dead corners such as the valve cavity and bends inside the filling head are prone to residual oil stains and the breeding of microorganisms. Residual moisture may cause an increase in acid value after mixing with oil. Although intermittent pressurized water flow to impact the pipeline can improve the cleaning power, it has a greater impact on the internal structure of the filling head, resulting in a shortened component life.

[0028] Among them, the bottom of the oil storage tank 1 is connected to an oil drain pipe 2, and an oil drain valve 3 is installed on the oil drain pipe 2. A mixing component 40 is arranged in the oil storage tank 1, which is used to stir the edible oil in the oil storage tank 1 to prevent the edible oil from settling in the oil storage tank 1. The oil storage tank 1 is connected to an oil supply pipe 41, and an oil supply valve 42 is installed on the oil supply pipe 41. The oil storage tank 1 is also installed with a pressure detection sensor 43 for detecting the gas in the oil storage tank 1.
[0029] Specifically, the mixing assembly 40 is composed of a mixing motor and a mixing frame.

[0031] Specifically, by starting the reflux positioning cylinder 11, the output end of the reflux positioning cylinder 11 can drive the reflux positioning column 10 to move, and adjust the state of the reflux positioning column 10. When the edible oil is poured, one side of the air pipe 12 needs to be connected to the air pump, and the treated clean gas is introduced into the air pipe 12 through the air pump. When the reflux positioning column 10 is in the backwash state, the gas in the air pipe 12 can enter the oil discharge pipe 2.
[0032] Among them, a boosting pipe 38 is connected between the gas supply pipe 12 and the oil storage tank 1, and a boosting valve 39 is installed on the boosting pipe 38. When the reflux adjustment column 10 is in the filling state, the boosting valve 39 is opened, and the gas supply pump can fill the gas into the oil storage tank 1 through the boosting pipe 38. The air pressure in the oil storage tank 1 is detected by the pressure detection sensor 43. By filling the oil storage tank 1 with air pressure, the edible oil in the oil storage tank 1 can be discharged more quickly.
[0033] As mentioned above, the oil delivery pipe 4 is connected and arranged on the side of the oil discharge pipe 2 away from the oil storage tank 1. The oil delivery pipe 4 is provided with a filling head group 002 with longitudinal adjustment movement. The filling head group 002 includes a filling pipe 5. A filling adjustment column 6 is sealed and slidably arranged in the filling pipe 5. The filling adjustment column 6 is in a backwashing state and a filling state in the filling pipe 5.

By heating the water in the clean water tank 23, the heated water flows through the water supply cavity and the return water cavity, and the oil pipeline 4 can be heated.
[0044] When pouring edible oil, the filling adjusting column 6 is driven to move by the output end of the flushing adjusting cylinder 15. When one side of the filling adjusting column 6 is in sealing contact with one end of the filling adjusting elbow 14, and the flushing area and the filling area are not connected to the filling adjusting elbow 14, the edible oil in the filling adjusting elbow 14 can be cut off.

[0045] When the filling is about to be completed, the oil discharge valve 3 is closed, and the reflux adjustment column 10 is moved to the backwashing state. By connecting the air pump on one side of the air pipe 12 and filling the air pipe 12 with clean gas through the air pump, the edible oil temporarily stored in the oil pipe 4 can be discharged through the filling pipe 5. After the edible oil in the oil pipe 4 is discharged, the oil pipe 4 is backwashed, and the flushing adjustment cylinder 15 is started to put the filling adjustment column 6 in the backwashing state, and then the return valve 1 20 is closed, and the return valve 3 29 is opened. The moisture in the clean water tank 23 can flow through the water supply cavity, the water supply pipe 17, the flushing area, the filling adjustment elbow 14, the oil pipe 4, the oil discharge pipe 2, the reflux pipe 9, and the return pipe 3 28 into the clean water tank 23, thereby realizing the circulation of clean water.
[0046] After the clean water dissolves and cleans the edible oil in the oil pipeline 4, close the clean water pump 26, the water supply valve 18 and the return valve three 29, start the clean water pump 33, the clean water valve 22 one and the clean water valve 22 two, and the water in the clean water tank 30 will be discharged from the clean water pipe two 34 through the clean water cavity, the clean water pipe one 21, the flushing area, the filling adjustment bend 14, and the oil pipeline 4 to flush the oil pipeline 4.
[0047] After the cleaning of the oil pipeline 4 is completed, the filling adjustment column 6 can be moved to the filling state, and gas can be blown into the oil pipeline 4 through the gas pipeline 12 to air dry the inside of the oil pipeline 4.
