Sesame oil is classified into a water-substitution method, also called a small grinding method, and a pressing method according to the preparation process, and the water-substitution method originates in the three-kingdom. The squeezing is firstly formed by pestle and pound in stone mortar, and then stone grinding is gradually used, so that the efficiency is improved, the quality is improved, and the prepared sesame oil is commonly called ground sesame oil. The oil preparation flow is as follows: sesame, screening, rinsing, seed frying, smoke raising, pulping, pulp stirring, shaking and oil skimming, crude oil treatment and finished oil treatment. Description: the sesame is rinsed and soaked for 1-2 hours, and the water content after soaking is 25% -30%. The seeds are fried with strong fire, after the surfaces of the sesame are swelled, the sesame seeds are fried with slow fire, 3 percent of cold water is added after the sesame seeds are fried, the sesame seeds are fried for 1 minute, and the sesame seeds are discharged from the pot after the tobacco leaves are discharged. Immediately cooling after taking out of the pot, and removing smoke dust, coke dust and broken skin. The grinding temperature should be kept at 65-75 ℃, and boiling water which is 80% -100% of the weight of sesame pulp is added for 4 times. The slurry stirring oil utilizes the specific gravity difference to enable sesame oil to float on the upper layer, and crude oil is produced.
The oil extraction process by the sesame squeezing method comprises the following steps: sesame, screening, rinsing, seed frying, smoke raising, blowing, squeezing, crude oil, precipitation and filtration, and sesame oil. The sesame cake obtained in the sesame squeezing process of the oil press can be squeezed for the second time.
Whether the sesame oil is produced by adopting a water substitution method or a squeezing method, after seeds are fried by using a roasting machine, the fried sesame oil is required to be smoked to remove smoke dust, coke powder and broken skin, and the sesame oil is aired into a flat tray for rapid cooling. In the current stage, all the smoke is blown by a fan, the dustpan is used for dumping cooked sesame above the flat tray manually, the wind blown out by the fan is wrapped with the wind to remove impurities, and the smoke dust, the coke dust and the broken skin are removed. However, due to the nonstandard manual operation, such as different pouring speeds and pouring heights, the impurity removal is often not thorough. The residual quantity of smoke dust, coke powder and broken skin is large, no matter which process is adopted, the subsequent oil outlet can be influenced, the quality of sesame oil is not only influenced, and the oil outlet rate can be reduced to a certain extent due to the adsorption effect of impurities.
In order to overcome the above problems, a new sesame impurity removal process is required.

Through setting up main shaft 3 as the hollow tube and outer end use rotary joint 13 to connect cold water supply unit, when stir-fry sesame needs to water cold water and take place the time, can be even throw into cold water, guaranteed the accuracy of cold water supply volume, for artifical water addition simultaneously, avoided the cold water to splash on the stir-fry cylinder 2 outer wall.
The working process of the roasting machine in the embodiment comprises the following steps: sesame seeds are added into the frying roller 2 from a material port, a heat source is started for heating, and a speed reducing motor drives the frying roller 2 to roll. The sesame is dehydrated and dried by using big fire at the beginning, in the process, the first electric control valve 8 is communicated with a positive pressure air source, the air bag ring 9 is inflated to block the ventilation gap, and the rolling sesame materials are prevented from entering the wind buckle cover 5 from the ventilation gap to cause waste. After the surface of the sesame bulges, the sesame is dried fully by slow fire, and the coke powder and the fragments are increased. At this time, when the first electric control valve 8 is communicated with the negative pressure air source, the air bag ring 9 is contracted, the ventilation gap is fully opened, the air valve 7 is also in an opened state, the exhaust pipe 6 starts to work, and negative pressure air carries coke dust and broken skin to be smoothly pumped away. After sesame is fried, cold water with mass specific gravity of 3% is added into the inner cavity of the frying roller 2 through the rotary joint 13, the main shaft 3 and the nozzle 14, the air suction mechanism continuously sucks air to enter a smoke discharge stage, and the smoke is discharged from the pot after 1 minute.
Example 3
As shown in fig. 5 and 6, an exhaust gas treatment system for connecting the exhaust pipe 6 in the above embodiment 2 includes a dust remover 15, an exhaust fan 16 and a drying seat 17 which are sequentially connected back through an air pipe, wherein the drying seat 17 is used for placing a drying basket 18, and the drying basket 18 contains cleaned sesame.
Specifically, as shown in fig. 6, the air-drying seat 17 includes an air-drying seat body and an air inlet pipe joint 171, the air-drying seat body includes a flat cuboid cavity structure, the air inlet pipe joint 171 is disposed at one end of the air-drying seat body, the other end of the air-drying seat body is opened, and the air inlet pipe joint 171 is connected with an air outlet of the exhaust fan 16 through an air pipe. A plurality of circular placing ports 173 are formed in the top plate of the main body of the airing base, and the airing basket 18 is placed on the placing ports 173. The bottom of the airing basket 18 adopts a gauze structure.
