Inline BRIX or refractometer tofu and soy milk l Inventech

Tofu contains many necessary nutrients for humans, while soy milk is a liquid produced when soybeans are cooked and crushed. The protein in soy milk is said to be nutritious and of high quality.To produce tofu, soybeans are soaked in water for a while and then, as more water is added, the beans are ground to make a paste (Namago). This paste is then boiled and strained, separating it into soy milk and "okara", or bean curd/tofu. Bittern (a coagulant) is added to the soy milk. After baking or frying, fried tofu is created.

Concentration measurement of Namago (bean paste) with inline BRIX

Namago (bean paste) can vary in concentration depending on the amount of moisture soybeans contain and how much water is absorbed during the soaking process. The concentration is adjusted by adding water depending on its hardness. While immersing and soaking the bean paste, a BRIX or concentration measurement is immediately performed.Soy milk can be divided into unadjusted, prepared soy milk and soy milk drinks, depending on the amount of soy remaining as a solid. This makes monitoring the soy concentration one of the important factors.

Inline BRIX measurement during tofu and soy milk mixing process

The mixing ratio feedback system of the in-line BRIX or refractometer measures the mixing ratio in real time and responds by changing the flow volume.

Inline BRIX or refractometer during bottling

A final check of the product before bottling is carried out to ensure it is within specifications. Controlling the switch between different fluids can help reduce fluid loss.When switching to a new liquid on the production line, it can be checked whether the concentration has changed or not.

Tip: concentration control cleaning solution

The inline BRIX meter can also be used to monitor the correct concentration level of the caustic soda or peracetic acid used to disinfect the piping system.
