AUTOMATIC ANNEALING

Automatic Tempering Machine is a very important tool in flour mills and ensures that the cleaned wheat has the desired moisture before milling with high precision. It provides a homogeneous exit moisture level regardless of the moisture content of the wheat received. Offering maximum hygiene, safety and ease of use, the machine has high performance and high yield capacity. With low periodic maintenance, minimum spare part replacement time and low energy consumption, the Automatic Tempering Machine is long-lasting and has high precision.

Tanis AUTOMATIC ANNEALING: Smart and Controlled Pre-Processing

Optimized Conditioning for Seeds, Grains, and Legumes

In seed, grain, and legume processing lines, pre-processing is critical for final product quality. Proper conditioning (annealing) balances shell hardness, optimizes internal moisture, and reduces breakage in subsequent machines.

The Tanis AUTOMATIC ANNEALING Machine performs this process in a fully automatic, precisely controlled, and sustainable way, ensuring minimal losses and maximized processing efficiency.


What is Annealing and Why It Matters?

Annealing is the process of adding controlled moisture to seeds or grains to achieve an ideal moisture balance between the shell and interior.

Benefits:

  • Softened Shells: Easier for peeling, cracking, or hulling machines.

  • Reduced Losses: Minimizes breakage, embryo damage, and dust formation.

  • Lower Energy Consumption: Less force required for hard shells.

  • Improved Processing Quality: More homogeneous, evenly moistened product.

Ideal for: Chickpeas, lentils, beans, sunflower, soy, flax, and hybrid seeds.


Working Principle: Controlled Moisture + Timed Resting

  1. Moisturizing Stage:

    • PLC-controlled dosing system applies precise water or steam amounts.

    • Nozzles or steam injectors distribute moisture evenly across product surfaces.

  2. Annealing Chamber:

    • Product rests in specially designed drum or screw chamber for a set period.

    • Shell softens while internal structure gradually absorbs moisture.

  3. Prepared Product Output:

    • Product exits in optimal condition for crackers, peelers, or selectors.

    • Ensures maximum efficiency with minimal energy.


Application Areas

  • Legumes: Chickpeas, lentils, beans, kidney beans

  • Oil Seeds: Sunflower, soy, flax, canola

  • Grains: Wheat, barley, rye (hard-shelled types)

  • Hybrid Seeds: Specialized and certified seed groups

  • Pre-Processing Lines: Before peeling, cracking, or hulling
