[0058] The working principle and use process of the present invention: when preparing monobutyrin, the raw materials need to be mixed and stirred. First, the raw materials are added to the top preparation barrel 12 through the feed pipe 21, and the stirring motor 18 drives the stirring shaft 19 and the stirring rod 20 to rotate to stir the raw materials. After the stirring is completed, the raw materials are input into the bottom preparation barrel 2 through the conveying pipe 15;

[0059] Then the solenoid valve 5 of the delivery pipe 15 is closed, the top preparation cylinder 12 continues to add raw materials through the feed pipe 21, and the bottom preparation cylinder 2 performs subsequent preparation operations, which not only can clearly divide the steps, but also can perform multiple steps at the same time, saving time, and the bottom preparation cylinder 2 and the top preparation cylinder 12 are stacked to save space;

[0060] When the bottom preparation cylinder 2 is opened, the clamping cylinder 11 can be moved upward and removed from the top of the bottom preparation cylinder 2 by rotating the rotating stopper 8 and the threaded block 9 to separate them from the threaded ring 7 and rotating the clamping ring 14 to separate them from the threaded ring 7;

[0061] When cleaning the clamping tube 11, the top preparation tube 12 and the top cover 16, the water inlet pipe 23 is moved toward the inside of the clamping tube 11, so that the clamping half ring 28 is clamped on the outside of the guide arc plate 26, and the limiting short block 27 is clamped between the two guide arc plates 26, until the water distribution pipe 24 completely enters the inside of the clamping tube 11, and the water is transported to the water distribution pipe 24 through the water inlet pipe 23, and finally sprayed to the inside of the clamping tube 11, the top preparation tube 12 and the bottom of the top cover 16, and then the stirring shaft 19 and the stirring rod 20 are driven by the stirring motor 18 to rotate, and the water is stirred and cleaned;

[0062] After cleaning is completed, the water inlet pipe 23 is pulled outward to make the limiting sealing block 25 fit the inner wall of the clamping tube 11 and cover the mounting hole 22. The movement of the water inlet pipe 23 does not affect the use of the device or the cleaning of the device.

[0063] During the preparation process, when it is necessary to sample and inspect the inside of the top preparation cylinder 12, first pull the metal cover 39 to pull the sealing cleaning block 34 and the pushing thin rod 35 outward by one end. At this time, the sealing cleaning block 34 is separated from the sampling inlet 33, and then the supporting spring 46 is squeezed downward by the toggle piece 45 to make the movable baffle 43 move downward and separate from the indicator plate 37. Then, the sampling inclined tube 30 is rotated 180° upward to rotate the sampling inlet 33 to the inside of the top preparation cylinder 12 and is in an open state. The mixture inside the top preparation cylinder 12 enters the sampling inclined tube 30 through the sampling inlet 33, and then the toggle piece 45 is pressed to rotate the sampling inclined tube 30 downward 180°. After the sampling inclined tube 30 is reset, the toggle piece 45 is released, and the supporting spring 46 pushes the toggle piece 45 and the movable baffle 43 to reset, and limits the indicator plate 37. At this time, the sampling The inlet 33 is also rotated downward to close, and finally the sealing cleaning block 34 and the pushing thin rod 35 are completely pulled out from the sampling inclined tube 30. The sample obtained in the sampling inclined tube 30 flows along the sampling inclined tube 30, and is finally collected from one end outside the sampling inclined tube 30. After the collection is completed, the sealing cleaning block 34 is inserted into the sampling inclined tube 30 for cleaning. Finally, after the sealing cleaning block 34 is cleaned, the sealing cleaning block 34 and the pushing thin rod 35 are inserted into the sampling inclined tube 30, and the card and groove 40 at the bottom of the metal cover 39 are clamped with one end of the indicator plate 37. The metal cover 39 is magnetically attracted to the magnetic ring 38, and sampling is achieved through the sampling inclined tube 30. There is no need to open the top preparation cylinder 12, nor is there any need to stop the preparation operation, which makes sampling more convenient, and the internal mixture can be checked in time to better grasp the preparation of monobutyrin.
