Tetra Alwin® Soy
Soya extraction unit

Highlights

Application

•t Lower bean cost thanks to high protein
extraction yield

A flexible production system for continuous extraction of both
beany and low-beany soya base from soya beans. The soya
base is blended, UHT-treated and packaged in subsequent
processing equipment.

•t Good flexibility to produce desired taste
•t Quick conversion from bean to product
•t Lower water consumption
•t Less product loss
•t Less environmental impact
•t Easy to clean with CIP
•t High production-to-footprint ratio
•t Consistent quality
•t Easy operation, with less risk of error

Working principle
Soya beans (whole or dehulled) are fed into a silo tank in the
grinding section. No prior soaking is required. The beans are
transferred by gravity via a dosing valve into a hopper, to which
hot water is added via a control valve. A positive pump transfers the beans and water to two grinders – a perforated disc
mill followed by a colloid mill – where they are ground to a
slurry for transfer to the fibre separation section. By controlling
the grinding temperature, a soya base with either a beany or
a low-beany taste profile can be achieved. In the latter case,
sodium bicarbonate may be added to further reduce the
beany taste.
