High-Low Dual Shaft Vacuum Mixer

Product Overview
The High-Low Dual Shaft Vacuum Mixer is special vacuum mixing equipment for meat products and pastry fillings. It adopts a staggered high-low parallel dual-shaft inclined paddle mixing structure, equipped with dual-speed dual-power motors. Mixing under vacuum negative pressure eliminates air bubbles inside fillings and fully precipitates meat protein, delivering finished products with excellent elasticity and bright color.
The whole machine is controlled by a microcomputer program, featuring pneumatic automatic lid opening and pneumatic discharge gate. Optional water-cooled refrigeration jacket and liquid nitrogen injection device are available on demand. It is suitable for processing air-dried sausages, meatballs, ham, dumpling & wonton fillings, pet meat slurry and other products, with complete CE and FDA export certifications.
Core Advantages
Staggered High-Low Dual Shaft Inclined Blades, Mixing Efficiency Increased by Over 60%
The rotation tracks of the two mixing shafts cross each other. Inclined paddles drive materials to tumble and circulate circumferentially at the same time, realizing dead-corner-free mixing. It automatically alternates forward and reverse rotation, cutting mixing time by 60% in actual tests. Dry powder, meat batter, ice water and fruit & vegetable additives blend evenly without agglomeration or stratification.
Dual-Speed Dual-Power Drive, Adaptable to Diverse Filling Processes
Single motor with dual-speed design allows switching between high and low speeds according to meat batter viscosity and production craft: low-speed gentle mixing fits delicate pastry fillings for dumplings and wontons; high-speed powerful mixing is ideal for air-dried sausages, ham, high-viscosity meat batter and wet pet food.
Vacuum Negative Pressure Mixing, Freshness Lock & Improved Elasticity, Pore-Free Fillings
The vacuum system puts materials under expanded negative pressure, completely removing internal air bubbles and maximizing the precipitation of meat protein. It improves water retention, elasticity and finished product yield, resulting in smooth cross-sections and bright color of final products.
Full Pneumatic Automatic Control, Labor-Saving Operation
Microcomputer programmable control system; both vacuum top lid and discharge gate open/close automatically by pneumatic power without manual operation. Multiple mixing formulas can be stored, and forward rotation / pause / reverse rotation cycles are automatically controlled to reduce labor intensity.
Easy-Disassembly Sealing Structure, Compliant with Food Hygiene Standards
High-strength nylon shaft heads with quickly detachable and replaceable shaft seals. The mixing chamber is fully made of SUS304 stainless steel without sanitary dead corners, which can be cleaned and maintained by direct water flushing.
Expandable Refrigeration & Liquid Nitrogen Injection System (Optional for Premium Craft)
A water-cooled refrigeration jacket can be installed on the machine body to maintain low temperature during mixing and prevent temperature rise & deterioration of meat batter. A matching liquid nitrogen injection device is also available for ultra-low temperature freshness locking, perfect for premium fresh sausages, high-end pet meat batter and top-grade prepared fillings.
