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 deactivation, dehulled soybeans are immediately ground. Combining blanching with hot grinding effectively minimizes beany odor. This method produces no effluent, supporting eco-friendly practices 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 bacterium common 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 to a precision feed system via bucket elevator (this feed system regulates material flow by adjusting the conveyor speed, ensuring the correct water-to-soybean ratio is maintained for optimal processing) → Proceed to the inactivation and softening stage: Introduce a measured amount of alkaline water (monitored by an alkaline flow sensor) during steam heating to deactivate key lipase enzymes. This step reduces the beans' natural smell and makes them more pliable for processing. Hot water is introduced into the coarse grinder in accordance with flow meter readings, combining with the treated soybeans (the heat helps dissolve proteins efficiently; soaking is unnecessary, resulting in energy savings and improved safety). Following grinding, the resulting soy milk moves into a separation chamber where liquid and solid residues are divided. To maximize protein yield, the initial bean residue is rehydrated and fed into a second separation stage, while the second-stage slurry is then ground again. The first-stage slurry is pumped via a centrifugal pump to a holding tank, and the clarified soy milk is then moved from there to the pasteurization and deodorization unit. Here, purified steam is directly introduced to heat the mixture to 130–140°C for 10–20 seconds, after which it enters a vacuum deodorizer to remove volatile odor-causing vapors. The material is then cooled to 90–95°C and discharged through a plate cooler (to preserve ideal taste and appearance, the soymilk must be rapidly chilled below 30°C). Finally, it is directed 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 soy 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 delivers superior throughput, featuring a multi-stage angled diversion system within the drying chamber that constantly redistributes and blends the material as it moves. This ensures broad and uniform heat contact, achieving excellent drying results with minimal operational expenses. Integrated cold and hot air recovery systems significantly reduce energy consumption.
2.    Soybean hull removal and separation system (Patent No.: ZL201320223568.0): This soybean processing unit, developed by our firm, efficiently handles high-volume pulp production lines and offers either single-stage or dual-stage hulling based on user needs. It integrates a hulling crusher, a hulling unit, and a screening component to ensure optimal 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 under 10mm in diameter are processed to remove their outer layer and crack. Once cracked, the bean hulls stuck to the bean valves within the crushing area are removed using a blowing bar, followed by the detachment of the hulls 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. Both the beans and their skins reach the bean skin separation vibrating screen. On the screen, the beans and skins spread out uniformly in a thin, even layer. The skin layer is drawn off by the cyclone system, while the cleaned beans exit through the discharge port. At this stage, the 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:
To ensure precise control, we've developed a dedicated feeding system for the metering feeder, allowing production needs to be met by simply adjusting the transmission speed. This system, equipped with flexible flow sensors in the deactivation softening unit, enables smooth and reliable regulation of soybean, water, soya, and alkali water proportions.
Soybean deactivation and softening unit: Consists of three main components—deactivation system, alkaline water setup, and hot water circuit. 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 measurement devices.
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, enabling seamless operation. This design also delivers extended service life and minimal upkeep requirements. The spacious hollow crushing chamber guarantees thorough and effective material reduction.
The refining mill employs 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, enhancing slurry and slag separation. Specifically designed for soybean milk and soy milk manufacturing, this machine offers straightforward operation and low maintenance requirements.
The user has the option to select a horizontal sedimentation slagging unit. This model outperforms the vertical design in performance, offers smooth uninterrupted operation, and handles higher throughput volumes.
6. The sterilizing and deodorizing equipment (patent number: ZL201220390580.6):
The unit's sterilizer is based on the design and operating method of a protein isolation sterilizer. Steam and the product combine within the piping system, ensuring a secure and dependable process.
b. The unit produced by our company adds a static mixer to make the steam and material mix more evenly.
c. Steam is filtered through a titanium alloy filter to ensure the purity of the steam.
d. The feed pump uses an adjustable flow volumetric pump that can regulated flow based on production needs.
e. The use of flashed secondary steam to preheat the material saves energy.
