The production technology process and features of equipment of Semi-dry wet soymilk production
A The technics characteristic of Semi-dry wet soymilk production:
( a ) The semi-dry wet soymilk technics adopts the internationally production technology, such as soymilk pulping equipment produced by Tetra Pak.
( b )The technics characteristic of Semi-dry wet soymilk production:
1.    Soybeans are dehulled after cleaned and dried to reduce the bitterness taste and remove contaminants and bacteria that adhere to the skin.
Soybeans require no soaking. After softening and inactivation, dehulled soybeans are immediately ground. Combining blanching with hot grinding effectively minimizes beany odor. This method produces no wastewater, supporting environmental sustainability and lowering expenses related to water waste management.
3.    The purification and odor removal stage uses high-temperature short-time treatment to thoroughly eliminate Thermophilic Bacillus, a heat-sensitive microorganism found in soybeans, and eliminates bean odors through vacuum flash distillation. This ensures soybean milk retains its natural freshness and delivers a superior, more pleasant flavor
4.    The entire production line is continuously produced and the materials are in the pipeline, which reduces the secondary pollution in the production process..
B  The production technology process
( a )Soybean pre-pretreatment production process: Soybeans undergo cleaning, drying, cooling, detritus and iron removal, followed by dehulling using a dehulling machine. The resulting dehulled soybeans are transported to the pulping stage via a lifter.
The main purpose of the pre-treatment is to remove impurities and remove the skin.


         


According to the technical requirement the burdening and homogenizing equipment can be placed before or after sterilization and deodorization.
Raw dehulled soybeans are transported via bucket elevator to a precision feed system, where the flow rate is finely tuned to ensure the correct water-to-raw material ratio for optimal processing. → Proceed to the inactivation and softening stage: a measured amount of alkaline water, monitored by a flow sensor, is introduced during steam heating to deactivate key lipase enzymes. This reduces the beans’ natural smell and makes them easier to crush. Hot water is then blended with the treated soybeans in a coarse grinder, guided by flow meter readings—this step helps dissolve proteins without requiring soaking, thus cutting energy use and enhancing safety. Following grinding, the resulting soy milk moves into a separation chamber to divide the liquid from the solid residue. To maximize protein yield, the initial bean pulp is rehydrated and fed into a second separation stage, while the second-stage slurry is recycled back into the grinding process. The first-stage slurry is pumped via a centrifugal pump to a holding tank, and the clarified soy milk is then sent to the pasteurization and deodorization unit. Here, purified steam is directly combined with the mixture, raising the temperature to 130–140 °C for 10–20 seconds before entering a vacuum deodorizer to remove volatile odorous compounds. The mixture is then cooled to 90–95 °C and discharged through a plate cooler—ensuring rapid cooling below 30 °C to preserve the ideal taste and appearance of the final product. The processed soymilk is then routed to the formulation stage.
C  The main production equipment features:
Harbin Modern Dairy Machinery Co., Ltd. specializes in machinery for producing semi-dry wet soymilk. Through over two decades of development and innovation, the company has refined key components and systems. The overall efficiency and functionality of the production line have been significantly enhanced.
( a )Characteristics of soybean pre-processing section equipment:
1.    Soybean Continuous Dryer: This unit is specifically designed as a high-efficiency continuous soybean dryer, unlike most local counterparts that rely on batch processing or basic box and fluidized bed systems. While batch and standard box dryers offer lower initial investment, they suffer from inconsistent heat distribution—leading to some soybeans not drying fully and others being exposed to excessive heat, causing scorching and compromising final quality. Fluidized bed dryers face limitations due to extremely short soybean exposure times, necessitating very hot inlet air. Our continuous dryer features a high throughput capacity, incorporating a multi-stage angled diversion system within the drying chamber to constantly redistribute and blend the material as it moves. This ensures broad and uniform heat exposure, achieving superior drying results with reduced operational expenses. Energy efficiency is further enhanced through integrated cold and hot air recycling.
2.    Soybean hull removal and separation system (Patent No.: ZL201320223568.0): This soybean hulling and separation unit from our firm is designed for high-pulp production lines and offers either single-stage or dual-stage hulling based on user needs. It features a hulling crusher, a hulling unit, and a screening component, ensuring efficient hulling performance.
3.    Basic structure and characteristics of soybean dehulling and separating equipment:
The system includes a peeling section, a crushing chamber, a bean coat separation screen, and additional components. Soybeans smaller than 10mm in diameter are processed to remove their outer layer and crack. Once cracked, any bean hull stuck to the bean valves within the crushing area is removed via a blowing mechanism, followed by the detachment of the hull from the system.
Once dried, soybeans are transported to the peeling section. The peeling process occurs through the combined effect of static and dynamic fluted discs. The bean fragments proceed directly to the impact chamber, while others go to the skin processing area, where residual skin clinging to the beans is easily removed. These beans and their skins reach the bean skin separation vibrating screen. On the screen, both beans and skins spread out uniformly in a thin, even layer. The skin is drawn off via a cyclone system, while the cleaned beans exit through the discharge port. In this process, soybean peeling efficiency reaches over 90%.
The unit is currently a relatively new device, designed and manufactured under the innovative ideas.
The machinery meets its intended objectives, boosting soybean shell removal during soy milk and soybean milk manufacturing, thereby enhancing the quality of both soy milk and soy milk powder.
( B )The Characteristics of pulp section equipment:
Precise control: Because of the non-linear relationship between the inclined screw's rotational rate and the material input, we have developed a dedicated feeding system for the metering feeder. The exact feed volume needed for production is achieved by adjusting the transmission speed. Using flow sensors in the deactivation softening unit, the proportions of soybeans, water, soy, and alkali water can be smoothly modified.
Soybean deactivation and softening unit: Consists of three main components—deactivation system, alkaline water system, and hot water system. The deactivation section uses stainless steel bearings, while both ends of the deactivated cylinder feature quick-release (clamp) connections, facilitating efficient cleaning and sterilization. The alkaline water setup includes two agitated low-level tanks and one high-level balancing tank. These tanks take turns receiving alkali to maintain uninterrupted operation and consistent alkaline water concentration. Hot water is generated via a plate heat exchanger to guarantee a steady flow. Both alkaline and hot water systems are fitted with flow sensors.
Stainless steel coarse grinder: All components that come into direct contact with materials are constructed from stainless steel. The transmission bearings use a single-piece design, maintaining precise alignment between the two bearing centers on the drive shaft, ensuring seamless operation. This design offers extended service life and minimal upkeep requirements. The spacious hollow crushing chamber guarantees thorough and effective material reduction.
The refining mill features a pelletizing unit that achieves fine material processing through high-speed pendulum motion. This process yields a particle size marginally larger than that produced by a colloid mill, which enhances slurry and slag separation. Specifically designed for soybean milk and soy milk manufacturing, this machine offers straightforward operation and reliable upkeep.
The user has the option to select a horizontal sedimentation slagging unit. This model outperforms the vertical version in performance, offers smooth uninterrupted operation, and handles higher throughput.
