Batches can be blended in 2 to 20 min, depending on nature of the material and degree of dispersion required. Because Matcon container system discharges material on a "mass flow" (first-in-first out) basis, there is no separation of product after mixing or during the discharge operation. This guarantees that homogeneous blend of product is retained during storage and throughout the discharge process until the container is empty. Blenders are ruggedly built to ensure safety and can be made fully automatic under the control of a PLC. Available in a range of sizes and can be supplied in mild-steel or stainless construction.

Xactablend continuous-processing blender has computer control for metering by weight loss. System is menu-driven with all variables such as process rate and individual ingredient volume entered through a simple function-key terminal. Memory for 25 different recipes makes repeat setups simple. Messages and instructions displayed on easy-to-read backlit An LCD screen that has its own light source from the back of the screen, making the background brighter and characters appear sharper.  LCD. Continuous analog weight-loss signals from each material hopper mounted on an individual load cell are received by a computer, allowing precise blends by weight regardless of bulk-density variations. Process rate is accurately matched by constant monitoring of the mixing chamber's high-level proximity sensor. When mixing chamber initiates a demand signal, the computer runs all ingredient feeders at required rates until satisfied.

Xactabatch weigh-scale batch blender is for two to six ingredients. Micro-processor control, utilizing two load cells mounted on a single weigh-scale hopper, weighs each ingredient dispensed and deposits the total batch into a mixing chamber. Programmable logic controls standard.
