Amino Acid Ribbon Mixer is a horizontal mixer that thoroughly mixes amino acid powder materials. It is primarily suitable for solid-solid mixing processes between amino acid powders and excipients, as well as between different types of amino acids. It is an indispensable core piece of equipment in amino acid production lines. Compared to ordinary powder mixers, the amino acid ribbon mixer is specifically optimized for the characteristics of amino acid powders, such as large differences in specific gravity, easy agglomeration, and poor flowability. The product can complete mixing in 3-15 minutes and can evenly mix different types of additives.
Amino acid powder materials exhibit a series of typical characteristics that distinguish them from ordinary powders during the mixing process. Different types of amino acids exhibit significant differences in particle morphology and true density. Lysine hydrochloride, threonine, and methionine, for example, have varying specific gravities, making them prone to segregation and stratification during mixing. This places high demands on the forced convection capability of the mixing equipment. Amino acid powders generally possess a certain degree of hygroscopicity and surface adhesion, easily leading to agglomeration and clumping during mixing. Therefore, the equipment needs to possess gentle yet effective shear dispersion capabilities. Amino acids are mostly heat-sensitive substances; frictional heating during mixing can cause crystal structure damage or loss of active ingredients. This necessitates that the mixer possess both high-efficiency mixing and low-shear characteristics, achieving uniform mixing in a short time while effectively controlling temperature rise.
The Amino Acid Ribbon Mixer mainly consists of four parts: a U-shaped cylinder, a double-layer spiral ribbon stirring rotor, a transmission system, and a discharge device. Each component works collaboratively to ensure the normal operation of the entire machine.
Cylinder: Typically designed as a U-shaped or cylindrical structure, with a feed inlet at the top, which can be equipped with a spray dispensing device as needed. The discharge device is installed at the center of the bottom.
Mixing Rotor: Mounted on a horizontal main shaft inside the cylinder, it consists of a shaft, cross braces, and helical ribbons. The helical ribbons are generally made with a double or triple layer structure. The outer helix gathers material from both sides towards the center, while the inner helix conveys material from the center outwards.
Transmission System: Includes a motor, reducer, and couplings. The motor is directly connected to the mixing main shaft via a cycloidal pinwheel reducer, resulting in a simple structure and reliable operation.
Auxiliary Configuration: The equipment can be made into a hot and cold jacket type to meet the needs of vacuum mixing and drying operations; the cylinder cover can be made into an open door structure for easy cleaning and maintenance.
The working principle of the Amino Acid Ribbon Mixer can be summarized as bidirectional convection mixing. When the motor drives the mixing main shaft to rotate through the reducer, the inner and outer double-layer helical ribbons mounted on the main shaft rotate synchronously: the outer helical ribbon gathers and pushes the amino acid powder from both sides of the cylinder towards the center in a certain direction, while the inner helical ribbon conveys the material from the center outwards in the opposite direction, forming two circulating material systems. In this repeated cyclical flow, materials are continuously lifted, dispersed, and remixed by the ribbon, accompanied by mutual diffusion and shearing between material particles. This allows amino acid powders of different types and specific gravities to achieve a highly uniform mixture in a short time.
A ribbon mixers are chosen for amino acid production because they offer high mixing uniformity and speed, capable of uniformly mixing multiple amino acid powders with significant differences in specific gravity in a short time, achieving a mixing uniformity of up to 1:10,000. Secondly, they have a high loading coefficient, typically exceeding 70%, allowing for large batch throughput to meet the needs of large-scale production. Furthermore, they exert gentle shearing force on the materials, preventing damage to the structure of amino acid crystals and active ingredients. The U-shaped cylinder bottom, combined with a large-diameter discharge gate, allows for discharge within 1-2 minutes, avoiding cross-contamination between different batches.

Does the amino acid mixer need to be made of stainless steel?
Yes. Amino acid powder is sensitive to metal contamination, and the production process has strict hygiene and safety requirements. 304 or 316L stainless steel has good corrosion resistance and easy cleaning properties, preventing material contamination and equipment rust.
How much can the amino acid ribbon mixer mix at a time?
The mixing capacity per batch depends on the equipment model and specifications. Commonly used models have loading capacities ranging from tens of liters to tens of thousands of liters. Specific capacity can be customized according to production needs.
Can the ribbon mixer mix multiple amino acids?
Yes. The ribbon mixer has bidirectional convection forced mixing capabilities, effectively overcoming problems such as large differences in specific gravity and varying flowability between different amino acids, mixing multiple amino acid powders and their excipients uniformly in a short time.
