Abstract

The invention discloses a vegetable fermentation system based on PLC, which is characterized in that it includes a PLC controller and an EM235 analog input module connected with the PLC controller, and the PLC controller is also connected with a valve, a configuration host computer, a touch screen, and a stirring motor , The magnetic pump is connected with the diaphragm pump, and the input terminal of the EM235 analog input module is connected with the temperature sensor, pressure sensor, PH sensor, dissolved oxygen sensor, and liquid level sensor. The present invention uses PLC control combined with a touch screen to monitor and modify production parameters on site in real time, with flexible control, and applies mechanical automation to semi-solid vegetable fermentation, which not only shortens the time for vegetable fermentation, but also effectively ensures the flavor quality of finished fermented vegetables .

Description

technical field [0001] The invention relates to the technical field of vegetable fermentation devices, in particular to a PLC-based vegetable fermentation system. Background technique [0002] At present, most of the traditional fermented vegetable production adopts manual workshops, and the microorganisms are wild lactic acid bacteria, yeast and mold contained in the raw materials themselves. Due to the open natural fermentation and pickling, the vigor and quantity of beneficial microorganisms cannot become the advantages of the fermentation system in a short period of time, the fermentation cycle is long, and the product quality is unstable. In order to prevent the proliferation of harmful microorganisms, a large amount of salt must be added, and a high-salt diet has been proven to be one of the main causes of cardiovascular and cerebrovascular diseases such as hypertension. do not match. At the same time, the natural fermentation process is extensive, even if high salt ...
