9. The remote automatic oil sleeving system for soy sauce production as claimed in claim 1, wherein the first pressure transmitter is mounted at the bottom of the fermentation cylinder and used for detecting the material pressure in the fermentation cylinder;
the second pressure transmitter is arranged at the bottom of the brine tank and used for detecting the brine pressure in the brine tank.
10. The system of any one of claims 1 to 9, which realizes a remote automatic oil casing method in soy sauce production, is characterized by comprising the following steps when oil casing is required:
(1) after initializing the system, setting the oil sleeving amount in the control box by a user;
(2) the first pressure transmitter detects the pressure of the material in the fermentation cylinder and sends a material pressure signal to the control box, and the second pressure transmitter detects the pressure of the brine in the brine cylinder and sends a brine pressure signal to the control box;
(3) in the control box, firstly, calculating and converting a material pressure signal into a material stock in the fermentation cylinder, and then calculating the residual capacity of the fermentation cylinder by using the material stock; meanwhile, calculating and converting the saline pressure signal into the saline storage in the saline cylinder;
(4) comparing and analyzing the residual capacity of the fermentation cylinder with the set oil covering amount, and simultaneously comparing and analyzing the salt water storage of the salt water cylinder with the set oil covering amount;
(5) when the analysis result shows that the residual capacity is greater than or equal to the oil sleeving amount and the salt water storage is greater than or equal to the oil sleeving amount, starting a corresponding salt water pump and a corresponding air valve, and pumping the salt water in the salt water tank into the fermentation tank until the oil sleeving amount is reached; otherwise, the corresponding saline pump and the pneumatic valve cannot be started, and the user is reminded to carry out manual treatment.
