Soybean Processing Machinery

Soybeans are processed for their oil (see uses below) and meal (for the animal feed industry). A smaller percentage is processed for human consumption and made into products including soy milk, soy flour, soy protein, tofu and many retail food products. Soybeans are also used in many non-food (industrial) products. Blanching of soybean is carried out to remove anti-nutritional ingredients. It is essentially a water heater with the provision for inserting and removing the containers of soybean. It has a central cylinder through which the hot flue gases pass to heat the water, which is stored in a concentric outer cylinder. The outer cylinder is insulated with asbestos rope to conserve heat. Soybean is placed in stainless steel perforated cages and immersed in the hot water. It consists of central heating cylinder, outer cylinder, asbestos rope insulation, stainless steel perforated cages, grate, stand and gate valve. A batch of 20 kg soy dal in four perforated cages is dipped into annular space for I hour at 100 °C. After treatment, the dal is air dried.
