Seed Dryers
Seeds must be properly treated to prevent mold or bacteria, and then fully dried to remove any remaining moisture and prepare the seeds for packaging.
Providing consistent and improved overall outcomes requires maintaining the right temperature and airflow in the seed drying process.
Air Monitor equipment can monitor burners on furnaces for efficient combustion and on blower feeds to monitor airflow rate and temperature, allowing users to tune the seed dryer system for energy efficiency.

Maintain Seed Viability
Ensure that air temperature and humidity never exceed the range necessary to ensure good germination rates for each specific type of seed.Improve Combustion Efficiency
Airflow measurement equipment can improve the process efficiency of seed drying equipment like furnaces and blowers.Accurately Measure Airflow
Air Monitor flow stations can be installed with little to no straight pipe run and measure accurately across a wide range of velocities.VOLU-probe SS – Stainless Steel Traverse Probe with Transmitter
The VOLU-probe/SS unique dual offset static pressure sensor and patented chamfered total pressure sensor design permit accurate measurement of the airflow rate in highly turbulent flow locations without the need for upstream air straightening means.
Applications include fluidized bed seed dryers/coaters, rotary drum dryers/coaters, thermal oxidizers, stack flow measurement, and more.
VELTRON DPT
The VELTRON DPT transmitter is a differential & multivariable transmitter with an automatic zeroing circuit. The circuit is capable of electronically adjusting the transmitter zero at predetermined time intervals while simultaneously holding the transmitter output signal. For transmitters operating in a moderately steady temperature location, this automatic zeroing function essentially produces a “self-calibrating” transmitter.
The transmitter is designed to maintain an accuracy of ±0.5% of natural span. It can maintain linear output signals on applications requiring velocity or pressure turndown of 5 to 1.
VELTRON DPT-Plus
This microprocessor-based ultra-low range pressure & flow “smart” transmitter is designed to convert the low magnitude pressure signal generated by an airflow station or probe and a temperature input into 4-20mA signals proportional and linear to flow (or pressure) and temperature. It is suitable for use in indoor and outdoor NEMA Type 4X hazardous locations.
The VELTRON DPT-Plus onboard microprocessor performs the functions of operating parameter selection, transmitter configuration, input/ output and display signal scaling, and transducer calibration. Embedded software performs span, flow, and 3-point “K” factor calculations. It comes equipped with a multi-line, backlit, graphical LCD for use during transmitter configuration and calibration, and to display multiple measured processes.
VELTRON II Transmitter
The VELTRON II is an ultra-low differential pressure “smart” transmitter designed to convert the low magnitude pressure signals generated by airflow stations and probes, or static pressure sensors into dual transmitter output signals (4- 20mA, 0-5VDC or 0-10VDC) linear to pressure or flow. With its ±0.1% of natural span accuracy, it is intended for the most critical and demanding industrial applications requiring the utmost accuracy and long-term stability.
The VELTRON II transmitter is furnished with an automatic zeroing circuit, which eliminates all output signal drift due to thermal, electronic, or mechanical effects. In a temperature-controlled space, the circuit essentially produces a “self-calibrating” transmitter.
More Details About Seed Dryers
Fluidized bed dryers are used to treat seeds with pesticides, fungicides, or other treatments to protect them from pests or diseases. The seeds are mixed in a slurry and then sent through a fluidized bed dryer to remove the moisture and prepare the seeds for packaging.
Failure of the airflow equipment to fully dry the seeds can lead to mold growth, toxin production, or discoloration and can reduce the shelf-life of the seeds. At the same time, failure to maintain the proper air temperature can cause problems since exposing seeds to high temperatures may force premature germination.
Airflow measurement systems can be used to monitor and control the fluidized bed drying process to optimize airflow and temperature and improve process drying accuracy and efficiency.
