There is no absolute understanding of what matters. After all, it is small craft brewing equipment, not large brewery equipment. It will be subject to the consideration of sensor cost and installation space. The saccharification process starts from the raw material silo transporting to the silo weighing, and then to the opening of the valve entering the pulverizer. The crushed malt powder is transported to the powder silo, and then the valve of the powder silo is opened and put into the saccharification pot. This process can be applied to equipment of more than 1 ton to reduce labor intensity and save labor. It can be automated, and the technology is mature.
The steam heating pots in the saccharification system can control the temperature, add water to control the flow, the mixed water can be controlled by the confluence valve, the pneumatic valve position feedback, and the empty material level detection are more practical. But some tests are also flashy, especially for craft brewing equipment. For example, the liquid level sensor measures the real-time liquid level in the pot. Water is added to the mashing pot by a flow meter. After the material is used up, there is an empty material level detection. It is a general look at how much is left in the pot, which is not as reliable as a liquid level gauge.
The diaphragm of this micro-pressure sensor is particularly vulnerable to damage and must be protected. The liquid level gauge in the boiling pot is even more difficult to use. The current capacity can be known before the pot is opened, and the liquid level will not be calm after the pot is opened. It’s not easy to see how much evaporated. You can only stop the heating and observe after calming down. This is all done by the liquid level gauge. The turbidity during wort filtration is generally seen with the eyes, followed by sampling and testing. If you want to detect real-time data online and control it, the cost is too high, the cheap is inaccurate, and the accurate is as low as 50,000 to 60,000. With such a system, you don’t know whether to sell equipment or sensors. The cost of sensors is far more than the device itself.
When the temperature of the automatic mashing system rises , the corresponding stirring will start according to the preset frequency, and the corresponding valve on the pipeline will open when the mash is poured. The pump starts . After the material is discharged, the valve and the pump are judged to be shut down according to the signal of the material level sensor. The temperature of the fermentation tank and the ice water tank is still controlled.
