Flexible Capacity
Flexible equipment configuration to match small workshops and large-scale factories, with a wide range of capacity options from 2,000 to 30,000 bottles per hour to meet different investment scales.
- Convenient Maintenance: The food-grade stainless steel body is easy to clean and corrosion-resistant, with universal spare parts and low later maintenance cost. The fully matched CIP cleaning system ensures long-term hygienic and stable production operation.
Classification of Plant Protein Raw Materials by Production Process
Process-oriented Classification for Beverage Production Lines
Different plant raw materials differ greatly in oil, starch, tannin and anti-nutritional substances, which directly determine pre-treatment, grinding, homogenization and stabilization processes. We divide raw materials into four categories based on processing difficulties and matching equipment solutions, to match customized production lines for various plant protein drinks.
High-Oil Hard-to-Homogenize Type
High oil content leads to easy separation of oil and water after grinding, so supporting high-pressure homogenizers, deoiling equipment and emulsification blending systems are required. Oil tends to float and cause layering; roasting, fine grinding, secondary homogenization and emulsification blending systems are equipped to maintain stable liquid system.
Raw materials: Walnut, almond, peanut, coconut meat, macadamia nut, etc.
High-Starch Sediment-Prone Type
Rich in starch substances, prone to sedimentation and tank sticking at low temperature, gelatinization and enzymatic liquefaction processes are essential. Starch will agglomerate and sink after cooling; starch hydrolysis, high-temperature blending and sterilization procedures are matched to reduce bottom sediment.
Raw materials: Soybean, oat, brown rice, millet, quinoa, etc.
Main Packaging Formats
The production line features strong compatibility and flexible switching between packaging formats, meeting demands of supermarkets, catering, distribution and other market channels:

Plant Protein Beverage Production Line & Production Process Guide
Plant protein beverages, represented by soymilk, coconut milk, almond drink and walnut milk, feature rich plant protein, natural nutrients and smooth taste, enjoying growing demand in the global healthy beverage market. Zhonglian Machinery supplies fully automatic plant protein beverage production lines integrating water treatment, pulping, blending, homogenization, sterilization, filling and packaging. With mature deodorization and homogenization technology and stable dual sterilization process, the lines are compatible with multiple packaging formats and cover capacities from small-batch to large-scale manufacturing, widely applied in mass production of various plant protein drinks.
The six core processes
- Raw Water Treatment Raw water undergoes multi-stage filtration, reverse osmosis and UV sterilization to produce high-purity water, avoiding impurities that affect beverage emulsion stability and flavor.
- Raw Material Pulping & Filtration Raw nuts and beans go through soaking, dehulling, fine grinding and slurry-residue separation to extract fine protein slurry with full retention of nutrients.
- Blending & Homogenization Mix protein slurry with sugar, additives and pure water per formula, then process vacuum deodorization and two-stage high-pressure homogenization for smooth and stable texture.
- UHT Instant Sterilization Ultra-high temperature tubular sterilization eliminates all bacteria and spores in seconds, maximally preserving protein activity and original flavor of raw materials.
- Filling & Secondary Sterilization Complete automatic filling and sealing in enclosed environment, then send to retort for secondary sterilization to greatly extend product shelf life.
- End-of-Line Packaging Defect removal via light inspection, air drying, date coding, labeling, film wrapping, case packing and palletizing to finish finished product packaging.
