Automatic control system for heating static state maintenance of soy sauce

Abstract

The invention discloses an automatic control system for heating static state maintenance of soy sauce, which comprises a maintaining tank, a pressure transmitter, a temperature sensor and a controller, wherein the maintaining tank is connected with a feeding pipe and a discharging pipe; a feeding control valve is arranged on the feeding pipe; a discharging control valve is arranged on the discharging pipe; the pressure transmitter is mounted at the bottom of the maintaining tank; the temperature sensor is mounted in the maintaining tank; and the pressure transmitter, the temperature sensor, the feeding control valve and the discharging control valve are respectively connected with the controller. Compared with the prior art, the automatic control system for the heating static maintenance of the soy sauce provided by the invention has the advantages that the operation of the heating static state maintenance is automatically controlled, the quality fluctuation caused by personal faulty operation is reduced and the product quality is increased.

Description

technical field [0001] The invention relates to the field of soy sauce production, in particular to an automatic control system for heating and statically maintaining soy sauce. Background technique [0002] Heating and static maintenance means that after the soy sauce is sterilized by high temperature, it enters the storage tank and maintains it for a period of time, and then it is discharged and cooled. The usual operation is that a system has three storage tanks, one for feeding, one for maintaining, and one for discharging, and they are constantly switched in turn. Therefore, higher requirements are put forward for the operation of the staff. During the heating process, the operator needs to pay attention to the liquid level of the maintained tank at all times. When the liquid level is full, the feed valve must be closed, and at the same time, another maintenance tank should be opened to discharge the material. valve, while keeping the temperature of the heating steady....

AI Technical Summary

Problems solved by technology

And so on, such operators need to pay attention to the maintenance time, the liquid level of the storage tank, and the opening and closing of the corresponding valves. The operation is more cumbersome, the spirit needs to be highly concentrated, and it is easy to cause quality problems due to misoperation.
