Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to edible oil vacuum cleaning equipment. Background Art

[0002] Acid value is an important indicator for measuring the quality of oils and fats, reflecting the degree of rancidity of the oils and fats. When the acid value exceeds the standard, it means that the oils and fats have deteriorated and may produce pungent tastes (such as rancid taste), which not only affects the taste of the food, but also reduces its safety. Oils and fats are prone to oxidation reactions under high temperature, oxygen, light and other conditions, generating harmful substances such as free fatty acids and peroxides. These substances further decompose to produce small molecular compounds such as aldehydes and ketones, which pose a threat to human health. The rancidity of oils and fats will lead to a decrease in their nutritional value, because the rancidity process will destroy the unsaturated fatty acids, vitamins and other nutrients in the oils and fats. Long-term consumption of edible oils with excessive acid value cannot meet the human body's needs for essential fatty acids and vitamins. For this reason, a edible oil vacuum cleaning device is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The oil inlet pipe 1 is fixedly connected to a valve 2, and the end of the oil inlet pipe 1 away from the valve 2 is fixedly connected to a vacuum tank 3. The bottom of the vacuum tank 3 is fixedly connected to an air inlet pipe 4, and the air inlet pipe 4 is fixedly connected to a one-way valve 5. The end of the air inlet pipe 4 away from the vacuum tank 3 is fixedly connected to a steam generator tank 6, and the steam generator tank 6 is fixedly connected to a water inlet pipe 16, and the water inlet pipe 16 is fixedly connected to a valve 4 17. An air outlet pipe 14 is fixedly connected to the top of the vacuum tank 3, and a valve three 15 is fixedly connected to the air outlet pipe 14. An oil outlet pipe 9 is fixedly connected to the vacuum tank 3, and a valve two 8 is fixedly connected to the oil outlet pipe 9. The end of the oil outlet pipe 9 away from the vacuum tank 3 is fixedly connected to the oil extraction system 10. By operating the control system 13, the one-way valve 5 is opened to introduce water vapor into the vacuum tank 3, so that volatile substances such as free fatty acids in the oil evaporate together with the water vapor. The water vapor with volatile substances such as free fatty acids is discharged through the air outlet pipe 14 to obtain edible oil with a lower acid value, thereby completing the cleaning of the edible oil and protecting human health from damage.

[0025] The heating system 7, the oil pumping system 10, the low-temperature heating system 11, and the vacuum system 12 are electrically connected to the control system 13. The valve 1 2, the one-way valve 5, the valve 2 8, the valve 3 15, and the valve 4 17 are electrically connected to the control system 13. The heating system 7 includes a heater, a temperature controller, a sensor, a distribution box, and power distribution equipment. The oil pumping system 10 includes an oil pumping unit, an oil pump, and a connecting rod string. The low-temperature heating system 11 includes a heating element, a temperature controller, a fluid circulation system, and a safety protection system. The vacuum system 12 includes an air pump, a piping system, a vacuum valve, a vacuum measuring device, and a control system 13. The control system 13 includes detection elements, transmitters, controllers, actuators, and other auxiliary equipment as well as control strategies and algorithms. The vacuum system 12 is controlled by the control system 13 to adjust the vacuum degree in the vacuum tank 3 to a state of -0.098 MPa. Then, the low-temperature heating system 11 is activated by operating the control system 13 to heat the edible oil to 240-260 degrees Celsius to prevent the edible oil from coming into contact with oxygen or excessively high temperatures, which would cause oxidation reactions and unnecessary conversions and damage the quality of the edible oil.

[0026] Working principle: First, the control system 13 is operated to control the vacuum system 12 to adjust the vacuum degree in the vacuum tank 3 to -0.098MPA. Then, the control system 13 is operated to open the valve 12 to transfer an appropriate amount of edible oil to be processed into the vacuum tank 3 through the oil inlet pipe 1. Then, the low-temperature heating system 11 is started by the control system 13 to heat the edible oil to 240-260 degrees Celsius. Then, the control system 13 is operated to open the valve 4 17 to input an appropriate amount of water into the steam generating tank 6 through the water inlet pipe 16. After the input is completed, the valve 4 17 is closed and the heating system is started by the control system 13. System 7 converts water into water vapor with a water vapor pressure of 0.01-0.02 MPa. The one-way valve 5 is opened by operating the control system 13 to introduce the water vapor into the vacuum tank 3, so that volatile substances such as free fatty acids in the oil evaporate together with the water vapor. The valve three 15 is opened by operating the control system 13 to allow the water vapor containing volatile substances such as free fatty acids to be discharged through the outlet pipe 14. The oil extraction system 10 is started by operating the control system 13 to open the valve two 8, so that edible oil with a lower acid value is extracted from the vacuum tank 3 through the oil outlet pipe 9 to obtain edible oil with a lower acid value, thereby completing the cleaning of the edible oil.
