Device for quickly detecting vegetable oil inspiratory capacity at normal temperature and normal pressure

Abstract

The invention relates to the field of detection, in particular to a device for quickly detecting the vegetable oil inspiratory capacity at normal temperature and normal pressure, which comprises a motor, an output shaft arranged on one side of the motor, a driving bevel gear arranged on the left side of the output shaft, a driven bevel gear is meshed with the driving bevel gear, a transmission shaft fixed at the upper end of the driven bevel gear, and a non-full-tooth gear is fixed at the upper end of the transmission shaft, the outer side of the non-full-tooth gear is meshed with a hollow inner tooth frame, a fixing rod is installed on one side of the hollow inner tooth frame, an oil barrel is fixed to the other side of the fixing rod, at least two sets of stirring rods are installed on the right portion of the output shaft, and stirring bowls are fixed to the other sides of the stirring rods. A sliding rail is installed at the lower end of the oil drum and slidably connected with a sliding way. Through the arrangement of the output shaft, the stirring rod, the stirring bowl, the driving bevel gear, the driven bevel gear, the transmission shaft, the non-full-tooth gear and the hollow inner gear frame, while oil in the oil drum moves up and down and left and right, the stirring bowl lifts part of the oil out of the oil liquid level and falls down, the oxidation reaction of theoil is greatly accelerated, and the detection progress is accelerated.

Description

Technical field [0001] The invention relates to the field of detection, in particular to a rapid detection device for vegetable oil inhalation under normal temperature and pressure. Background technique [0002] Vegetable oils, especially newly refined refined vegetable oils, are oxidative and instability in aspiration; food grade packaging material PET is polyethylene terephthalate, currently on the market for beverage or vegetable oil filling bottles, PET packaging After the bottle is filled and capped, the oil bottle becomes a sealed system. In addition to the change in the temperature of the vegetable oil that affects the deformation of the bottle, the inhalation of the gas or oxidation reaction of the vegetable oil in the upper part of the bottle will also affect the pressure change in the bottle, which will cause the bottle body to deform and lift. The above phenomenon greatly affects the quality of products in the terminal market. The industry mainly adopts nitrogen-filled...

Problems solved by technology

[0002] Vegetable oil, especially the newly refined refined vegetable oil, has oxidation and gas absorption instability; food-grade packaging material PET is polyethylene terephthalate, currently on the market for beverage or vegetable oil filling packaging bottles, PET packaging After the bottle is filled and capped, the oil bottle becomes a sealed system. In addition to the deformation of the bottle due to the temperature change of the vegetable oil, the vegetable oil itself absorbs the gas above the bottle or the oxidation reaction will also affect the pressure change in the bottle, which will cause deformation of the bottle body. The above phenomena greatly affect the quality of products in the terminal market. The industry mainly adopts the nitrogen-filled fresh-keeping method to ensure the appearance quality of oil products and bottles; at present, there is no device for quickly detecting the nitrogen-filled fresh-keeping effect. Therefore, it is urgent to develop one. A scientific and simple detection device for the suction capacity of PET-packed vegetable oil

[0003] After retrieval, Chinese Patent No. is CN109738327A patent, discloses a kind of vegetable oil under normal temperature and pressure rapid detection device for air absorption, including a test bottle, the test bottle includes a glass bottle body and a bottle cap. There are holes; the stirring mechanism is used to stir the vegetable oil in the test bottle; the transparent air pipe, one end of the transparent air pipe is inserted into the glass bottle, and the other end is provided with a water column; wherein, the stirring mechanism stirrer stirs the bottle Vegetable oil in the bottle, the gas content in the vegetable oil in the bottle will change or oxidize, and the volume of the gas at the top of the bottle will increase or decrease, thereby pushing the water column to move, and the air absorption of the measured vegetable oil can be quickly observed and calculated through the moving distance of the water column, and timely Adjust the nitrogen filling process of different batches of vegetable oil filling, save the cost of nitrogen filling, and improve the efficiency of production and detection; The area is only a cross section of the bottle, which does not effectively promote the oxidation reaction
